Abstract
Previous research on the exchange rate affecting foreign direct investment (FDI),
generated mixed results. This study examines the link between real exchange rate
and FDI in the Eurozone, using quarterly data from top investor countries
between 1999 and the second quarter of 2016, subdivided in industry
specifications. In addition, other relevant determinants are investigated to explain
short-run mergers and acquisitions (M&A) flows. Empirical results show no
significant effect of the exchange rate in investor country combined analysis.
However, country-specific results highlight the significant positive correlation
between a depreciating Euro and Canadian high R&D acquisitions in the
Eurozone. Combining empirical evidence and recent literature to date, the firm-
specific asset theory for Canadian M&A in the Eurozone can be confirmed.

1. Introduction
1.1. Research aim and relevance
In recent years, more and more listed- and non-listed European firms fall into foreign hands.
Through mergers and acquisitions (M&A, hereafter) control of these companies is relinquished to foreign
say. According to UNCTAD’s1 World Investment Report 2016, foreign direct investment (FDI hereafter)
flows to Europe show a large increase during the year 2015. FDI went up almost 65 percent in comparison
to the year before, to an inflow of 504 billion Dollar. The expansion of FDI flows to developed countries is
primarily driven by a surge in cross-border M&A activity during the year, since deal making in Europe
went up with 36 percent. Next to the largest target country in Europe, the United Kingdom, Ireland has
become runner-up with M&A sales of 48 billion Dollar and France reached a historical 44 billion Dollar in
value in 2015. Main acquirers of the European assets were multinational enterprises (MNE hereafter) from
developed countries, the majority of which are located in North America, and China.
Multiple studies try to explain causes of swings in M&A flows. Traditional trade theories argue
that FDI is a result of comparative costs when international trade did not equalize factor prices. This theory
dates out of a time where the bulk of MNEs were located in the U.S. and a large portion of their investments
was located in less developed countries with lower costs, according to Blonigen (1997). He argues that
traditional theories concerning FDI are possibly explaining long run flows of FDI, but offer no clear
explanation of short-run movements. In addition, these theories do not explain the recent movements into
Europe, since Europe is not generally seen as a less developed region.
Martynova and Renneboog (2008) observe recurring surges and downfalls in M&As and examine
these different waves and underlying motives. They state that takeovers occur as a result of external
economic, technological, financial, regulatory, and political shocks. The waves usually occur in periods of
economic recovery (following a market crash and economic depression) and accompany rapid credit
expansion, which in turn results from external capital markets that prosper, and stock market booms. These
waves can take length of up to multiple decades and might offer little evidence for short-run fluctuations in
M&A activity in recent years.

While reports point out an increase in European M&A inflows, the value of the Euro compared to
several currencies has declined in recent periods. Figure 1 shows the number of Eurozone acquisitions by
large foreign investor countries and the corresponding bilateral real exchange rates (amount of Euro per
unit of foreign currency). The graph shows short-run movements in Eurozone inward FDI which are
unlikely explained by sudden adjusted comparative costs or transaction costs between countries in the
Eurozone and developed investor countries. However, the fluctuations in the bilateral exchange rate next
to the FDI inflows might suggest some valuable explanatory power.
The declining value of the Euro in recent years and the increasing amount of FDI of foreign firms
in Europe could raise concerns that Eurozone firms can be acquired at bargain prices. Froot and Stein (1991)
explain with their relative wealth effects theory, that depreciation of target companies’ currency, can

provide foreign firms an advantage. A low Euro could increase relative wealth of non-Eurozone companies,
making it easier to invest in Eurozone countries. Blonigen (1997) on the other hand focusses not on the
price of the asset but states that the rate of return of an asset should be relevant when acquiring a firm-
specific asset. These assets can generate returns in several markets and currencies at the same time without
any foreign currency transactions are needed, by enhancing plant efficiency of the acquiring firm for
example.
While a large amount of research tried to supply evidence for the effect of exchange rate variation
or level on FDI, not all studies find an unambiguous significant relationship. This study aims to provide
new information and evidence on the effect of exchange rate level on the amount of cross-border M&A
FDI in the Eurozone, while previous studies focused primarily on U.S. data and to a lesser extent, Japanese
data. Furthermore, time periods in which previous empirical tests have been done are quite outdated. The
effect and coefficients in this relationship found may be specific to the period of time considered. This study
will test if the effect of exchange rate level will be applicable for data concerning countries in the Eurozone
to possibly help explain cross-border M&A flows.
1.2. Problem statement
In order to examine the effect of exchange rate level on FDI, the main research question this study
will try to answer is:
Does the currency exchange rate level affect foreign direct investment mergers and acquisitions into the
Eurozone?
1.3. Research questions
Sub-questions to help answer the main problem statement are:
What are foreign direct investments?
What are the determinants of FDI M&As?
What is the effect of the exchange rate on FDI M&A?
What is the effect of other influencing factors on FDI M&A?
Is the effect of a depreciating Euro on FDI M&A more positive in manufacturing than non-
manufacturing industries?
Is the effect of a depreciating Euro on FDI M&A more positive in high R&D than low R&D
manufacturing industries?

1.4. Outline
The second chapter contains the theoretical framework. This chapter will elaborate on the
dependent variable and will discuss the factors considered in this study. The aim of this chapter is to explain
the research questions and form hypotheses to answer the main problem statement. The third chapter serves
as a pivot where the theoretical section is connected to the empirical research methodology. Furthermore,
research data used to conduct this research, accompanied by the descriptive statistics, are being presented.
Chapter four will consist of the empirical results of the conducted tests. Chapter five will discuss the derived
insights of the research, test the hypotheses formed in chapter two and will analyze these results in contrast
with previous work discussed in the literature review. In addition, the implications and limitations of this
study will be discussed. Finally, this research concludes with chapter six, containing a brief summary and
conclusion.

2. Literature review
2.1. Foreign direct investment
The dependent variable of interest in this study is the number of foreign direct investment mergers
and acquisitions into the Eurozone. FDI is an investment by an individual or firm from one country, in
business assets located in another country. FDI has two primary components: the form of greenfield
investment2 in a foreign country or by acquiring business assets to gain lasting controlling interest or
ownership of the foreign firm. A cross-border M&A is a component of the latter category, as an existing
target firm is obtained by a foreign acquirer.
Where foreign portfolio investment contains solely purchasing equities of foreign-based firms, the
crucial characteristic of foreign direct investment is that the investment made in a company establishes
effective control or substantial influence over the foreign firm.
FDIs are generally categorized as horizontal, vertical or conglomerate direct investments.
Horizontal direct investments indicate that the company conducts the same type of business operation in
the target country as it is engaged in in its home country. In the case of vertical direct investment, the
operation is different than the acquiring firm’s main business but is still related to it. Acquiring and
integrating a foreign supplier of components used in a manufacturing process is an example of foreign
vertical direct investment. In the case of a conglomerate type of FDI however, the investment in a business
is unrelated to the existing main business of the investor and involves entering an unfamiliar industry.
2.2. The link between currency exchange rate and FDI
There have been many theoretical and empirical studies investigating the link between the exchange
rate and FDI. Traditional belief is that the currency exchange rate levels should not affect the incentive to
invest. McCulloch (1991 p. 179) states: “if a U.S. asset is seen as a claim to a fixed stream of future Dollar-
denominated profits, and if those profits will be converted back into the domestic currency of the investor
at the same exchange rate, the level of the exchange rate does not affect the present discounted value of the
investment.” So If exchange rates are considered a random walk and the price to acquire an asset and the
return of that asset are expressed in the same currency, the relative valuation of the asset will stay unaffected
for either domestic or foreign buyers. However, McCulloch (1991) does add to this argument that if profits
are generated by activities that require imported inputs or by exporting outputs to other markets, the value
of the profits in the domestic currency may not typically be independent of exchange rate fluctuations.
2 A greenfield investment is a form of FDI where a parent company builds its operation in a foreign market from the
ground up. Greenfield investments are distinctive as the operation construction is done to its own specifications and
employees are trained focused on the standard of the investing company, so that the fabrication process can be highly
controlled.
J.P. van Doorn 10
At the same time, several empirical studies do reveal a possible correlation between a depreciating
currency and increasing FDI inflows, especially acquisition FDI. The observed correlation tends to confirm
the belief that assets and technology can be acquired at bargain prices by foreign firms when the domestic
currency is weak. Among others, Froot and Stein (1991), Klein and Rosengren (1994), Swenson (1994),
Blonigen (1997) and Georgopoulos (2008), tested and found a link between currency exchange rate level
and FDI inflow. Other studies such as Ray (1989) and Stevens (1998) have included exchange rate as a
factor in their empirical model and found a weaker or no significant effect on movements in FDI.
While the research mentioned above focuses on the effect of exchange rate level, early papers by
Cushman (1985 and 1988) investigates the impacts of long-run exchange rate volatility on FDI. Cushman
(1985) constructs a theoretical firm-level model of international investment where four different forms of
company regimes are examined, distinctive in exchange rate expectations, trade linkages and financing
options. Greater uncertainty or risk due to exchange rate fluctuations would encourage FDI as a substitute
for exports. The empirical research of Cushman (1985) finds a positive relationship of exchange rate
volatility on FDI outflow data from the United States to Canada, France, Germany, Japan and the United
Kingdom. Cushman (1988) analyzes FDI flow into the U.S. from these countries and also finds a positive
impact of exchange rate volatility.
Froot and Stein (1991) were one of the first offering an interpretation for the correlation found
between the exchange rate level and FDI. Their research and reasoning imply a distinct relationship when
capital markets are imperfect. They state (p. 1191): “as the dollar declines relative to its long-run
equilibrium value, the returns on all dollar assets will fall as well, and hence the prices of these assets will
rise. There are no “steals” to be had by foreigners.” We live in a world with high (and even more increasing)
mobility of capital and if a foreign firm has an advantage acquiring a domestic firm with his own currency,
why is it not possible for another domestic investor to borrow the complete amount in the foreign currency
and acquire the firm? Froot and Stein (1991) build their relative wealth effects theory on information
asymmetry and lenders tend to charge a premium for monitoring costs. Because of this asymmetry, it will
be very costly or even impossible for investors to finance an asset entirely with external capital. They state
(p. 1194): “the more net wealth an entrepreneur can bring to such an “information-intensive” investment,
the lower will be his total cost of capital.” Froot and Stein (1991) emphasize the link between an investors’
wealth position and investments, which extends in the relationship between the exchange rate and FDI
acquisitions. Foreign firms hold a majority of their wealth in their own currency denominated form and an
appreciation of this currency compared to for example the Dollar, boosts the relative wealth position of the
foreign firm. This will lower the relative cost of capital of this firm because of the contribution of its own
capital and provides more financial capacity to outbid U.S. domestic firms.
J.P. van Doorn 11
This effect is illustrated by an adjusted example of the one Froot and Stein (1991) use. Both a Dutch
and a U.S. investor take part in the auction of a Dutch windmill park. The turbines will provide revenues
of 100 EURm in the following year. The Dutch and U.S. investor can both get a loan on the same terms,
but the bank will only lend up to 90 percent of the total acquiring price. The Dutch firm holds 7 EURm of
own funds and the U.S. investor has 5 USDm of cash available. With an exchange rate of 1 USD/EUR, the
U.S. investor can bid as high as 50 EURm, while the Dutch Investor can bid up to 70 EURm and will win
the auction. In the case the Euro depreciates and the current exchange rate is 0.5 USD/EUR, the U.S.
investor’s wealth increases to 10 EURm, he can bid up to 100 EURm and will win the bidding. The
depreciation of the Euro has increased the relative wealth of the U.S. investor.
In the example above capital is mobile. The U.S. bidder can access the same external capital as the
domestic Dutch investor. The imperfection lies in the information about the assets that are acquired. This
will not be equal for every type of asset or investment. Passive investment portfolios with bonds and stocks
are not that information sensitive according to Froot and Stein (1991). These investments could practically
exclusively be financed with external capital and therefore, it is expected that portfolio flows are not highly
correlated with exchange rates. In the case of FDI acquisitions however, it is very likely to encounter
information asymmetry. In their empirical section, the exchange rate is regressed on inflows of FDI into
the U.S., for the period 1973 to 1988 in thirteen different industries. For all thirteen separate industries,
coefficients of exchange rate level show negative signs. Five of these coefficients are statistically significant
and the strongest effect is seen in the manufacturing industries, indicating that a depreciating U.S. Dollar
leads to greater FDI inflow.
Not everyone agrees with the statement of Froot and Stein (1991). Stevens (1998) for example,
mimics and criticizes their research. He states that their findings are not robust for subsamples within their
original chosen sample period and when the period is extended to 1991, the exchange rate variable is
insignificant in this relationship. Blonigen (1997) indicates that Froot and Stein (1991) provide an important
first step in linking exchange rate fluctuations to FDI movements, but leave certain important matters
unanswered. He states (p. 450): “First, while their wealth effect need not distinguish the effect of exchange
rate movements on different types of FDI, their empirical findings present evidence that various forms of
FDI respond differently to the exchange rate changes. Second, it may be empirically difficult to distinguish
relative wealth gains from currency movements compared to other factors affecting firm wealth.” Blonigen
(1997) cites the Japanese FDI flow in the U.S. in the late 1980’s. Did Japanese firms experience wealth
gains from the fluctuations in exchange rates or from the speculative bubble in Japanese real estate markets
and stock market? This potential influence will be addressed later on.
The relative wealth theory of Froot and Stein (1991) assumes that the price of the acquired asset is
relevant. Blonigen (1997) presents in his paper theoretical and empirical evidence, showing that not the
J.P. van Doorn 12
price of an asset, but the rate of return of that asset should matter when a foreign firm locates abroad.
Traditional arguments essentially assume that assets acquired in foreign FDI are similar to bonds or
comparable assets where the price and nominal return are both in the same currency. Blonigen (1997) states
that this is not necessarily the case when observing mergers and acquisition FDI, because the target’s assets
are often in the form of firm-specific assets, which can generate returns in several markets and currencies
at the same time, without any foreign currency transactions. The model of Blonigen (1997) leans on the
assumption that the firm-specific assets, such as innovations or technology for example, are easily
transferable within the acquiring company and are able to generate returns in not just the currency the assets
are acquired with. A depreciation of the target country’s currency lowers the bidding price of the asset for
foreign investors, but this depreciation does not affect the returns. Therefore, should the depreciation of the
target firm’s currency, increase FDI inflows into the target firm’s country. While Froot and Stein (1991)
find that imperfections on the capital market cause a link between currency exchange rate movements and
FDI, Blonigen’s theory (1997) assumes the imperfection of goods markets. A domestic target firm has
limited or no access to the foreign market relative to the foreign firm to sell its output. For example, suppose
both a Dutch and a U.S. company have an equal opportunity to acquire a Dutch firm with a valuable
transferable innovation. Depreciation of the Euro compared to the Dollar will increase the net present value
of the firm for the U.S. company, since the cost of purchasing the Dutch firm will decrease. In the case of
imperfection of the goods market, the net present value of the asset for the Dutch bidding firm does not
change, because it has no (or less) access to the U.S. market compared to the bidding U.S. firm.
Blonigen (1997) empirically tests his hypothesis using data on Japanese acquisitions in the United
States across multiple industries from 1975 to 1992. Previous research has provided evidence that Japanese
M&A FDI into the U.S. is strongly driven by technology-related and firm-specific asset acquisition motive.
These useful and valuable technology is more common in high research and development (R&D hereafter)
manufacturing industries, therefore it is likely that Blonigen’s (1997) theory is supported in these industries.
The data on the Japanese acquisitions in the United States in the sample time period confirm the theory,
displaying a strong correlation between periods of a weaker U.S. Dollar and a higher amount of M&A FDI
in the U.S., for industries which more likely involve firm-specific assets. This effect however, is not found
in greenfield FDI. One critique on the analysis of Blonigen (1997) that he mentions in his empirical results
section (p458 – 459): “R&D expenditures may be a proxy for other characteristics of an industry that would
make a Japanese firm more likely to acquire in that industry when the dollar depreciates. Perhaps high R&D
industries are also the ones that are relatively more capital intensive.” This remark connects his theory and
findings with the capital market approach of Froot and Stein (1991), which suggests that industries that are
capital-intensive gain more benefit from depreciation of the exchange rate.
J.P. van Doorn 13
Other researchers re-examine Blonigen’s (1997) theory. Georgopoulos (2008) tests the hypothesis
by linking cross-border FDI acquisition data between U.S. and Canada to the exchange rate level. This
research’ empirical results are consistent with the asset acquisition hypothesis of Blonigen (1997) for high
R&D intensive industries. While Georgopoulos focusses on single country inbound FDI activity, Lee (2013)
examines the proposed link between exchange rate and FDI using M&A FDI data from multiple country
sources that are inbound for various countries in the period 1989 to 2007. The result of Lee’s (2013) study
provides evidence that Blonigen’s (1997) suggested link between the exchange rate level and asset-seeking
acquisition FDI can be confirmed for U.S. inbound acquisition, but not for inbound M&A FDI in other
various developed countries. The analysis of Lee (2013) finds that Blonigen’s (1997) evidence is mainly
driven by U.S. inbound M&A data. When he excludes the U.S. data and only inbound acquisition FDI into
other foreign countries are considered, support for the hypothesis could not be found. This may sound
feasible, since the United States spend the most on R&D in the world (2016 Global R&D Funding Forecast3)
and can be considered the largest marketplace for technology, and may attract asset-seeking cross-border
acquisitions. Lee (2013) states that another explanation might be that the U.S. market is more open to
foreign direct investments in comparison with other countries such as Japan for example.
This study examines the influence of the exchange rate level of the Euro on the amount of M&A
FDI inflows into the Eurozone to see if Blonigen’s (1997) asset acquisition hypothesis will hold for this
sample, as no study did this before. The effect of the currency exchange rate level will be examined instead
of volatility, since interest lies in investments to enrich firms by acquiring valuable firm-specific assets for
a lower price and not acquisitions to mainly diminish exchange rate risk. Blonigen’s (1997) theory depends
on the imperfect goods market assumption as an explanation why domestic firms cannot generate equal
returns in the foreign country where the currency has appreciated. The effect of the exchange rate risk shall
be reduced when assuming that firm-specific assets produce higher profits without the need of additional
exchange rate exposure. However, with a low stable value of target’s currency, firm-specific assets are still
very attractive as it may improve plant efficiency of the acquirer for example.
Previous studies have mostly focused on U.S. inbound FDI or on U.S. outbound FDI. Therefore,
literature primarily tested the exchange rate effects almost exclusively with U.S. data and to a lesser extent,
with Japanese data. Furthermore, the time periods in which previous empirical tests have been done are
quite outdated. Blonigen (1997) for example, tested his theory ranging from 1975 – 1992, Georgopoulus
(2008) 1985 – 2001 and Lee (2013) for the period 1989 – 2007. The effect and coefficients in this
relationship found may be specific to the period of time they considered.

This study will test if the effect of exchange rate level will be applicable for data concerning
countries in the Eurozone. Europe contains multiple well-developed countries, which contribute over 20
percent of global R&D spending (2016 Global R&D Funding Forecast). Therefore, manufacturing and non-
manufacturing industries will be distinguished. Furthermore, manufacturing industries will be divided into
high and low R&D industries to test the firm-specific asset acquisition theory on Eurozone firms.
2.3. Domestic acquisitions by other Eurozone firms affecting FDI inflows
Literature states that even in an increasing international economy, domestic acquisitions are still
the largest portion of mergers and acquisitions. Cross-border M&A inside the Eurozone is likely to take
place due to reduced distance and a similar currency for example. These transactions are not directly
influenced by a depreciation or appreciation of the Euro and can contain other relevant influences on the
FDI inflows from non-Eurozone firms that help to explain the main question of this research.
Without supply, a transaction cannot be accomplished and to capture the industry firm supply
component, Blonigen (1997) includes a variable capturing the amount of domestic acquisitions by other
U.S. firms. This variable should control for the overall domestic M&A activity and target firm supply. If
the of quantity of M&As is large internally, chances are that also internationally the number of incoming
deals will be higher. He expects a positive correlation between the supply variable and number of foreign
acquisitions in an industry. His expectation is confirmed by his empirical results, where the domestic
acquisition coefficients show a positive sign and are statistically significant. Lee (2013) also includes a
domestic acquisition factor in his model, similarly constructed as the main dependent variable: FDI M&A.
The coefficients in his result section also show a (small) positive but strong significant statistical effect.
Dewenter (1995) approaches the potential influence of domestic acquisition activity in another way.
In her research examining the relationship between the value of the dollar on cross-border acquisitions into
the U.S., she tests her variables on both the absolute level of FDI flow and the FDI controlled for overall
level of investment activity. Her relative FDI independent variable is constructed as foreign investment
relative to domestic acquisitions.
This research will take into account the domestic M&A activity in the model since this is an
appropriate control variable. This factor captures a favorable acquisition environment, unrelated to
exchange rate fluctuations and contributes to a stronger explaining model. Internal Eurozone M&A is not
explained by the main explanatory variable, the currency exchange rate. However, by adding this
investment supply variable, the effect of internal cross-border Eurozone M&A activity on the inflow of FDI
out of the Eurozone is taken into account.

2.4. The effect of the real GDP growth rate on FDI
Froot and Stein’s (1991) theory suggests that even appreciating foreign wealth independent of
exchange rate, will generate an increase in FDI. Gross Domestic Product4 (GDP hereafter) is commonly
used as an indicator of the economic health, country’s standard of living, or productivity. When GDP
growth is adjusted for inflation you get the real GDP growth, which can be used to measure nation’s
economic growth (or decline) and is positively related to wealth.
Di Giovanni (2005) estimates the effect of multiple macroeconomic, financial and institutional
factors, to explain cross-border M&A flows. He includes various factors, including real GDP for both the
acquiring and target country to measure a countries economic size. His regression output shows a positive
significant effect for both variables.
While Blonigen’s (1997) uses U.S. domestic acquisitions as a control variable to measure supply
characteristics, his research inter alia controls for Japanese demand for U.S. target firms by including a
variable that captures annual real growth of Japanese GDP. His empirical results show a significant positive
link between the real GDP growth and Japanese acquisitions in the United States and, when looking to the
full sample period, consistent with the expected positive correlation. However, when a distinction is made
between high and low R&D manufacturing firms, the coefficient on GDP real growth rate is only significant
and positive for high R&D manufacturing companies.
In imitation of Blonigen (1997), Lee (2013) includes the real GDP growth rate in his empirical
specification to control for the demand side factor. He expects that appetite for M&A will be higher for
foreign countries with economies that grew over the years. The real GDP growth rate variable in his results
has a positive coefficient and are statistically significant, meaning that higher GDP growth increases the
demand for FDI M&A in his data sample.
According to previous literature, coefficient signs of real GDP growth of the acquirer’s nation on
dependent variable cross-border FDI, are not all equal and significant but seem to be a potential good control
variable complementing the empirical model of this research.
2.5. Growth of stock market price index affecting FDI
Earlier in this study, Blonigen’s (1997) possible alternative explanation for the movements in
Japanese acquisition FDI, especially the large spikes in the late 1980’s and early 1990’s, was cited. The
boom of U.S. firms acquired by Japanese investors could be explained as consequence of the speculative
“bubble” economy during those years, as Blonigen (1997) defines it. The speculative bubble is potentially
4 GDP is the monetary value of all the finished goods and services produced within borders of a particular country in
a specific time period. It includes the private and public consumption, government expenditure, investments and net
exports (the value of total exports minus total imports).

highly correlated with exchange rate fluctuations in the late 1980’s and early 1990’s and therefore, is a
potentially relevant factor. Froot and Stein (1991) mention this development as additional support to their
theory that shocks to wealth, other than exchange rate driven, can help explain U.S. FDI inflows. “Between
the end of 1987 and early 1991, the real value of the yen did not change importantly; yet the rate of Japanese
net FDI inflows increased until the end of 1989 (nearly doubling during those two years), and then fell.”
(Froot & Stein, 1991, p. 1215). Their imperfect capital markets approach explains why internal cost of
capital is lower than borrowing from external capital resources. If a foreign stock market grows, wealth of
the foreign firm will grow and provide more capital to acquire a certain asset.
Klein and Rosengren (1994) measure the relative wealth by creating a factor that represents the
value of the U.S. stock market to an index of the value of the stock market of a foreign country. They find
a significant negative influence of the relative wealth variable on inward U.S. acquisitions when the trend
factor is added in the regression. Their use of time trend allows controlling for increasing presence of
foreign ownership in the U.S.
Di Giovanni (2005) expects that cash is key in financing cross-border transactions, but a rebounding
equity market could increase the use of equity in deal financing. In addition, improving equity prices could
boost confidence among firms’ board to pursue acquisition tactics.
To take this possible relationship into account, Blonigen (1997) includes the annual growth in the
Tokyo Stock Price Index as a regressor, with an expected positive coefficient. When examining the
empirical results, a significant positive sign is found in the “all industries” column, less or no significance
for the (non-)manufacturing subdivision. Lee (2013) mimics the assumption above and constructs a stock
market variable to capture wealth effects from the stock market. The variable contains annual growth rates
of each of the foreign country’s representative stock market price index. Lee (2013) however, finds no
statistically significant effect in his empirical model of the stock market factor on FDI.
Multiple researchers added the foreign stock market index variable to capture wealth effects of
foreign investors from stock market fluctuations. Martynova and Renneboog (2008) examined the large
M&A waves, and state that these usually occur after a market crash and periods of economic depression.
The time period used in this research includes among others a portion of the speculative Dot-com bubble
and its burst and the global financial crisis plus both recovery periods. Adding the stock market factor could
therefore possibly increase the explanatory power of the empirical model.
2.6. Omitted factors
This study focusses primarily on the exchange rate affecting FDI, although certain variables that
are likely to influence FDI due to their economic effects and previous literature, are added. There are many
J.P. van Doorn 17
researchers that try to extend models and add many more different variables in the model that are not
feasible or essential relevant for this study.
Blonigen (1997) tries to control for alternative explanations that account for fluctuations in
acquisition FDI in the United States. He includes an industry-specific U.S. protection variable in his model
to account for tariff-jumping5, because this explanation for incoming FDI may be relevant for Japan in his
sample period. Japan could invest in the U.S. during this period, to avoid the newly established protection
mechanism. But when his empirical estimations are examined, the U.S. protection variable has no
significant effect and seems no explanatory variable. Blonigen (1997) explains this insignificant coefficient
may occur since, in his model, the effect of protection is tested over time, while FDI fluctuations may be
affected by the protection variable only around the time such mechanisms are put into place. Secondly, he
addresses that the U.S. protection may be higher in industries where alternative variables diminish FDI
activity.
Another frequent variable of interest concerning FDI is taxation. There is a large amount of research
that focus primarily on the effect of taxation on FDI and Blonigen (2005) discusses a number of them in
his review of empirical literature on FDI determinants. In summary, there are many varying conclusions
about this relationship. A MNE faces tax rates at a variety of levels and possibly in both the target and
parent country. In addition, there are many tax treaties, which negotiate tax reductions in countries’
withholding rates (Blonigen, 2005), and the empirical approaches and data samples differ considerably in
the literature, stating no clear one minded effect.
The tax variable and import tariff or domestic protection variable are omitted from this research.
The protection variable turned out to have no explicit and significant effect in previous studies, making it
unlikely that this is a primary explanatory variable. Furthermore, it is unavailable and almost impossible to
display all sectoral import mechanisms between the Eurozone countries and the largest investor countries
in the data sample. The same argument applies to the taxes factor, since most tax treaties and their content
are not generally known and, at the level of disaggregation of the data, are unavailable.
2.7. Research hypotheses
In order to answer the research questions in this study, several hypotheses are presented. The
hypotheses have the purpose to mainly clarify the connection between the exchange rate and M&A FDI for
the Eurozone. In addition, the relationship of the control variables is tested on the independent variable: the
number of FDI M&A into the Eurozone.
5 Tariff is a tax imposed on imported goods and services. They are often used to regulate trade by increasing the price
of imported goods. Tariffs can be described as a government tool to shape trade policies and are often used to protect
domestic industries from foreign competition.
J.P. van Doorn 18
Many theoretical and empirical studies have failed to ensure a unanimous opinion on exchange rate
affecting FDI. While traditional theory states that currency fluctuations should not affect the incentive to
invest, Cushman (1985) argues and finds that greater uncertainty due to exchange rate fluctuations would
encourage FDI as a substitute for exports. Froot and Stein (1991) construct their relative wealth effects
theory to offer interpretation for the correlation found between exchange rate level and FDI. Multiple
researchers found mixed results on the relationship of interest. These studies primarily tested the effects
almost exclusively with U.S. data and to a lesser extent, with Japanese data. Furthermore, the effect and
coefficients in this relationship found may be specific to the period of time they considered. Therefore, the
effect of a depreciating Euro on FDI inflows in a more current time period will be tested by the first
hypothesis.
Hypothesis 1: A depreciation (appreciation) of the Euro, increases (decreases) the number of incoming
FDI acquisitions into the Eurozone
M&As inside the Eurozone are not directly influenced by a depreciation or appreciation of the Euro
and may contain other relevant influences on the FDI inflows from non-Eurozone firms that help to explain
the main question of this research. To account for supply of target firms inside the Eurozone and measure
the effect of domestic M&A activity on FDI inflows in the Eurozone of foreign countries, hypothesis 2 is
constructed.
Hypothesis 2: Higher (lower) number of domestic acquisitions, increases (decreases) the number of
incoming FDI acquisitions into the Eurozone
Froot and Stein’s (1991) theory suggests that even appreciating foreign wealth independent of the
exchange rate, will generate an increase in FDI. GDP is commonly used as an indicator of the economic
health, country’s standard of living, or productivity. When GDP growth is adjusted for inflation you get
real GDP growth, which can be used to measure nation’s economic growth and should affect the wealth of
the investor country. When affecting relative wealth of an investor, exchange rate level should have a larger
influence and increase FDI. To test this effect, hypothesis 3 is configured.
Hypothesis 3: Higher (lower) foreign GDP growth rates, increases (decreases) the number of incoming
FDI acquisitions into the Eurozone
J.P. van Doorn 19
Multiple researchers added the foreign stock market index variable to capture wealth effects of
foreign investors from stock market fluctuations. Di Giovanni (2005) argues that a rebounding equity
market could increase the use of equity in deal financing. In addition, improving equity prices could boost
confidence among firms’ board to pursue acquisition tactics. Blonigen (1997) adds the variable to his model
because the boom of U.S. firms acquired by Japanese investors could be explained as consequence of the
speculative “bubble” during the years covered in his sample. The sample period covered in this study
contains the recession following the Dot-com bubble and the global financial crisis. Therefore, hypothesis
4 examines whether stock market shocks affect FDI.
Hypothesis 4: Higher (lower) growth rate of the acquirer’s stock market price index increases
(decreases) the number of incoming FDI acquisitions into the Eurozone
Blonigen’s (1997) firm-specific asset acquisition hypothesis argues that with a low value of the
target’s currency firm-specific assets such as technology, are very attractive. Easily transferable technology
is acquired at a discount due to a depreciation of the target country’s currency and can provide more
efficiency or return for the acquiring firm. The multiple well-developed countries in the Eurozone,
contribute to a large part of global R&D spending. To test if depreciation of the Euro, increases the foreign
incentive to buy technology more “cheaply”, this study will distinguish manufacturing and non-
manufacturing industries and, in manufacturing industries, distinguish high and low R&D industries. To
test the firm-specific asset acquisition theory on Eurozone firms, hypotheses 5 and 6 are constructed.
Hypothesis 5: The effect of a depreciating (appreciating) Euro on the number of incoming FDI
acquisitions, is more positive (negative) for manufacturing industries than non-manufacturing industries
Hypothesis 6: The effect of a depreciating (appreciating) Euro on the number of incoming FDI
acquisitions, is more positive (negative) for high R&D manufacturing industries than low R&D
manufacturing industries

3. Research methodology
3.1. Empirical model
To test the hypotheses mentioned in the previous chapter and be able to answer the main research
question of this study, the determinants of the dependent variable are specified in a relationship estimation
equation. The basis of this study’s model relies on the equation relationship projected in equation 1.
3.1.1. Empirical specification

3.1.2. Variable definition
3.1.2.1. The number of FDI M&As into the Eurozone
Number of FDI M&As into the Eurozone is the variable of interest in this research. The number of
acquisitions is chosen rather than the value because deal value is often not necessarily disclosed. The
dependent variable in this study is measured as FDI acquisitions of firms in the initial Eurozone6 countries,
from the time stock prices are indicated in terms of the Euro. Therefore, period of interest in this research
is 4 January 1999 up to 30 June 2016. The top investor countries considered in the analysis are Australia,
6 The countries which acceded to the Eurozone at establishment in 1999 are: Austria, Belgium, Finland, France,
Germany, Ireland, Italy, Luxembourg, Monaco, the Netherlands, Portugal, San Marino and Spain. Vatican City has
been omitted due to deficiency of data available.

Canada, China, Japan, the United Kingdom and the United States, as they represent the economies with
highest values of net purchases of cross-border M&As, that are not included in the Eurozone.7 This study
includes deals in the dataset when the investing firm owns at least 10 percent in the Eurozone based
company after de purchase. According to the Organisation for Economic Co-operation and Development
(OECD), FDI is an investment that reflects the objective of establishing a lasting interest from a firm in one
economy in a firm that is located in another economy. The investment implies a long-term interest of the
investor in the acquired assets and a significant degree of influence on the management. The ownership of
10% or more of the voting power of an enterprise is the threshold for establishing a controlling interest,
according to OECD guidelines8.
To see if Blonigen’s (1997) firm-specific asset theory is applicable to the Eurozone and current
time period, the model will be tested on different industry data samples. Aside from total all industry FDI
M&As, a distinction between non-manufacturing and manufacturing industries is made. Furthermore, high
and low R&D manufacturing industries are disaggregated to test if the theory of Blonigen (1997) will hold.
Greenfield investments are disregarded from this study because the interest is in (non-)tangible transferable
technological or licensable assets. In addition to acquiring proprietary assets, acquiring a domestic firm
might accelerate the gain of market presence for the foreign company, which is not the case in greenfield
investments.
3.1.2.2. Real exchange rate
The main independent explanatory variable is the quarterly logged real exchange rate level
expressed as the domestic currency of the Eurozone, the Euro, per unit of foreign currency. The real
exchange rate is explicitly used instead of nominal exchange rate because price levels could also affect
investment decisions. The real exchange rate is corrected for differences in price level between the two
countries, while the nominal exchange rate is not. In imitation of Lee (2013), this study uses logarithms of
the quarterly individual real exchange rates, allowing for the percentage changes of different exchange rates
to be comparable, interpretable and less influenced by potential outliers.
The Eurozone is seen as a developed economic area with a relatively high amount of high
technology firms. According to the firm-specific asset theory, a foreign firm could acquire valuable assets
at a lower price when the domestic currency devaluates. The real exchange rate variable, denominated in
Euro per foreign currency, is therefore expected to have a positive effect.

J.P. van Doorn 22
3.1.2.3. Domestic M&As inside the Eurozone
To capture industry and country supply characteristics, the number of domestic acquisitions inside
the Eurozone by Eurozone countries is implemented in the model. This variable represents overall M&A
activity in the Euro area in an industry and includes the aspects of a convenient acquisition environment,
which are not related to the real exchange rate.
An area, with high M&A activity and a sufficient supply of targets, is likely to attract foreign
investors. The relationship between domestic M&A and incoming FDI in the Eurozone is expected to be
positive.
3.1.2.4. Real GDP growth
Real GDP is an inflation-adjusted measure of the value of all goods and services produces in an
economy during a specific period. Unlike nominal GDP, real GDP is corrected for changes in price level
of a country and therefore provides a more accurate measurement of economic growth. The real GDP
growth is used in the model so that growth rates of the different countries are easier to compare.
The real GDP growth variable is used to measure demand for FDI. Higher economic growth should
increase the demand for investments and M&A. Therefore, a positive relationship between the real GDP
growth of the investor country and FDI M&A into the Eurozone is expected.
3.1.2.5. Stock market price index growth
Growth of the investor country’s stock market price index is added to the model to capture demand
for FDI, which is not necessarily generated by real exchange rate changes. This independent variable
measures the wealth effect of stock price changes of the leading stock market index of every country and
also controls for possible effects of stock market bubbles and crashes that might affect the FDI acquisition
decisions of firms located in one of the investor countries. Stock market price index growth is used in the
model to compare growth rates of the different leading stock markets of each country.
The stock market growth variable is included to control for its influence on demand and is
expected to have a positive relationship with the dependent variable of this research.

3.2. Data and variable construction
3.2.1. Number of FDI M&As into the Eurozone
Number of FDI M&As in the Eurozone by foreign firms is constructed from data retrieved from
SDC Platinum. This database provides extensive information on deals such as target and acquirer nation,
allowing to narrow the deals down to Eurozone target nations and the large investing countries as acquiring
nationality. In this way, the effects can be measured over the full time period used in this model. The time
period 4 January 1999 to 30 June 2016, contains 119,549 M&A deals with Eurozone target nations. As
foreign out-of-Eurozone acquiring firms, companies located in the six large investor countries are used.
When filtering out other acquiring nations than the six mentioned earlier, 14,563 deals remain.
Furthermore, the database yields information of the percent of shares owned after the transaction.
Accounting for the OECD threshold of 10% mentioned before, results in a remaining 10,969 FDI take-
overs in the Eurozone.
In addition, SDC Platinum also specifies the target firm’s SIC9 code for each deal enabling to break
down the deals into four-digit SIC level industries and distinguish 3,936 manufacturing industry deals and
6,909 non-manufacturing industry deals10. Within the manufacturing industries, subdivision gives 2,240
high R&D industry acquisitions and 1,696 low R&D acquisitions.11
9 Standard Industrial Classification (SIC) codes are four-digit numerical codes assigned by the U.S. government to
business establishments to identify the primary business of the establishment. The first two digits of the code identify
the major industry group, the third digit identifies the industry group and the fourth digit identifies the industry. 10 Manufacturing and non-manufacturing deals do not add up to total deals, because not all SIC codes in the dataset
are compliant. 11 Following Blonigen (1997), SIC codes between 2000 and 3999 are manufacturing industries, which can be
subdivided into high and low R&D industries. High R&D industries are SIC 2810-2899, 3510-3599, 3650-3679, 3710-
3729, 3760-3769 and 3810-3899. Low R&D industries are all other manufacturing industries. High R&D industries
are determined as those where expenditures on R&D as percentage of sales, are at or above average of the
manufacturing industry.

J.P. van Doorn 24
When categorizing the deals into the quarters of each year, the dependent variable data at industry
subdivision level and country pair for each quarter in the relevant time period of this research is constructed.
3.2.2. Real exchange rate
Main independent explanatory variable in this research, the real exchange rate, is constructed using
the quarterly nominal exchange rate of the foreign currencies to one Euro. Share prices on the stock
exchanges of initial Eurozone countries are displayed in the Euro since 4 January 1999. Therefore, the first
quarter of 1999 is the starting period of this study. The exchange rates used are the WM/Reuters closing
spot rates, retrieved from Thomson Reuters Datastream. To adjust them to Euro per unit of foreign currency,
1 is divided by the extracted nominal exchange rates. The interest is in the logged real exchange rate and is
calculated with formula 2.
𝑙𝑛𝑅𝐸𝑅𝑖𝑗𝑡 = 𝐿𝑛 (𝑒𝑡 ∗ 𝑃𝑗𝑡
𝑃𝑖𝑡) (2)
Where:
𝑙𝑛𝑅𝐸𝑅𝑖𝑗𝑡 = Logged real exchange rate of the currency of country 𝑖 for country j at time 𝑡
𝑒𝑡 = Nominal exchange rate at time 𝑡
𝑃𝑗𝑡 = Consumer price index of country 𝑗 at time 𝑡
𝑃𝑖𝑡 = Consumer price index of the Eurozone at time 𝑡
The quarterly consumer price index (CPI, hereafter) with base year 2010, for every investor country
and the Eurozone, are obtained from OECD Data.12
3.2.3. Number of domestic Eurozone M&As
The number of domestic M&As in the Eurozone is constructed with a similar approach as the
dependent variable of this study, the number of FDI M&As into the Eurozone. As mentioned before, SDC
Platinum provides 119,551 deals with a Eurozone company as target firm. 90,060 of these deals are closed
between two initial Eurozone parties. Correcting for the FDI threshold of at least 10 percent owners stake
leaves 64,609 of total domestic Eurozone M&As in the relevant time period.
Using the industry SIC codes to split the deals, 43,374 Non-manufacturing industry acquisitions
during the sample period are found and manufacturing industry deals sum up to a total of 20,549.
Subdivision of the manufacturing industry counts 7,700 high R&D and 12,849 low R&D take-overs. When
categorizing the deals into the quarters of each year, the independent variable data at industry subdivision
level and country pair for each of the 70 quarters between 1999 and 2nd quarter of 2016 is constructed.

3.2.4. Real GDP growth
Investor countries’ quarterly real GDP are retrieved from Thomson Reuters Datastream for the
period 4th quarter 1998 to 2nd quarter 2016. The GDP data seasonally adjusted prices with constant prices
are selected to obtain the real GDP growth, unaffected by price changes. To adjust the data to growth of
real GDP, formula 3 is used:
𝑅𝐺𝐷𝑃𝐺𝑗𝑡 =𝑅𝑒𝑎𝑙 𝐺𝐷𝑃𝑗𝑡−𝑅𝑒𝑎𝑙 𝐺𝐷𝑃𝑗𝑡−1
𝑅𝑒𝑎𝑙 𝐺𝐷𝑃𝑗𝑡−1
(3)
Where:
𝑅𝐺𝐷𝑃𝐺𝑗𝑡 = Real GDP growth of country 𝑗 at time 𝑡
𝑅𝑒𝑎𝑙 𝐺𝐷𝑃𝑗𝑡 = Real GDP of country 𝑗 at time 𝑡
𝑅𝑒𝑎𝑙 𝐺𝐷𝑃𝑗𝑡−1 = real GDP of country 𝑗 at time 𝑡 − 1
3.2.5. Stock market price index growth
Quarterly leading stock market price indices of the relevant investor countries are retrieved from
Thomson Reuters Datastream from the 4th quarter of 1998 to 2nd quarter of 2016. For Australia, data of the
All-ordinaries Stock Index, a stock index comprised of common shares from the Australian Stock Exchange,
is used. The All-Ordinaries Index is the most quoted benchmark for Australian equities. S&P/TSX
Composite Index is used to observe the stock market in Canada. This index contains stocks of the largest
companies on the Toronto Stock Exchange. China’s stock market is measured by the Shanghai Stock
Exchange Composite, made up of all the A-shares and B-shares listed on the largest stock exchange in
mainland China, to get a broad overview of the performance. Tokyo Price Index (TOPIX) is used as a
metric for stocks on the Tokyo Stock exchange. The TOPIX provides an appropriate representation of the
Japanese stock markets. For United Kingdom’s stock market data, the Financial Times Stock Exchange
(FTSE) All Share price index is included. This index is used as data for broad measuring the stock market
fluctuations on the London Stock Exchange. Finally, representing the United States stock market, the S&P
500 Composite price index is included. This index is seen as a leading indicator of the performance of
United States equities. To adjust the stock market indices to growth numbers, formula 4 is used.
𝑆𝑀𝑃𝐼𝐺𝑗𝑡 =𝑆𝑡𝑜𝑐𝑘 𝑀𝑎𝑟𝑘𝑒𝑡 𝑃𝐼𝑗𝑡− 𝑆𝑡𝑜𝑐𝑘 𝑀𝑎𝑟𝑘𝑒𝑡 𝑃𝐼𝑗𝑡−1

Table 3
Descriptive statistics
Table 3 displays the descriptive statistics of the main variables used in this study. All variables are constructed by
using quarterly data from 1999Q1 to 2016Q2 for the six investor countries. N = 420, n = 6 and T = 70. All estimates
are rounded to 3 decimals.
Note: SIC codes between 2000 and 3999 are manufacturing industries, all other are non-manufacturing industries.
High R&D industries are SIC 2810-2899, 3510-3599, 3650-3679, 3710-3729, 3760-3769 and 3810-3899. Low
R&D industries are all other manufacturing industries.
J.P. van Doorn 27
3.2.6. Descriptive statistics
Table 3 presents the summary statistics of the datasets, which contain the 6 investor countries with
70 quarters of data. The summary statistics show that the overall standard deviation of the FDI M&As into
the Eurozone is larger than its mean in all industries. However, most of the variation in the dependent
variable is caused by deviation between investor countries rather than within a country. The table shows
that on average more non-manufacturing firms are acquired rather than manufacturing firms. Furthermore,
on average more high R&D firms are targeted compared to low R&D firms, which can probably be
explained by the relatively technological well developed Eurozone.
The logged real exchange rate deviation is larger between countries, which is expected since the
price level of the multiple currencies are at different heights compared to each other. (e.g. Japanese Yen
per Euro is considerably higher than American Dollar per Euro)
The standard deviation of the Eurozone domestic M&As variable is equal to zero between the
investor countries, because the panel variable investor country does not influence the number of acquisitions
in the Eurozone.
3.3. Statistical procedures and analysis
The variables constructed with the data mentioned in the previous section are merged in a strongly
balanced panel dataset. The panel variable in this model is country, representing the investor country, and
time variable is expressed in quarters, from 1999 to the second quarter of 2016. The panel nature of the
dataset allows for the distinguishing of the variables on country level. This empirical study starts with the
construction of a scatter plot of the dependent variable and the main explanatory variable.
Before the effects of the independent variables on number of FDI M&As are examined, the
statistical soundness of this study’s regression model is investigated. The error terms of the empirical model
are assumed to be identically and independently distributed (I.I.D.). To test if this assumption holds, the
presence of different common statistical problems in regression analyses are investigated and controlled
for.
The first problem examined is serial correlation or autocorrelation, which shows smaller estimated
standard errors of the coefficients than they actually are. Autocorrelation occurs when the error terms in a
panel data model are correlated with each other and thus are not independently distributed. This study
examines different investor countries over multiple quarters and it is most likely that different observations
of an investor country are correlated. To test for serial correlation, a Wooldridge test for autocorrelation in
panel data (Wooldridge, 2002) is performed.
If error terms do not have a constant variance and are non-identically distributed, heteroskedasticity
occurs. Heteroskedasticity does not result in biased coefficient estimates, but causes biased standard errors.
J.P. van Doorn 28
This affects the test statistics and confidence interval for interpretation of the measured effects. To test for
heteroskedasticity for the fixed effects model a modified Wald test is conducted, for the random effects
model a Likelihood-ratio test for heteroskedasticity, based on Breusch and Pagan (1979) is performed.
In addition to the potential statistical complications mentioned above, a too strong correlation
between two or more predictor variables can be problematic. Multicollinearity can be the cause of skewed
biased results regarding the coefficients of the independent variables that explain the dependent variable.
Presence of multicollinearity can increase standard errors of the correlated independent variables, which
can cause problems when interpreting the results. First, a correlation matrix is produced to monitor the
dependence between the multiple variables considered in this model. For properly testing if predictor
variables in the model are highly correlated to one another, a Variance Inflation Factor (VIF, hereafter)
matrix is constructed. “a VIF of 10 indicates that (all other things being equal) the variance of the 𝑖th
regression coefficient is 10 times greater than it would have been if the 𝑖th independent variable had been
linearly independent of the other independent variable in the analysis.” (O’brien, 2007 p. 684). So, the VIF
measures how much the variance of the regression coefficients estimated in the model, are inflated because
of the linear dependence with other independent variables.
To analyze the panel data, as starting point an ordinary least squares model (OLS, hereafter) is
assumed to measure the effect of the independent variables on the dependent variable as Wooldridge (2002)
suggests. Table A.1. in the Appendix displays the yearly FDI acquisitions into the Eurozone per investor
country. With the exception of the year 1999, when the Dot-com bubble did not yet burst and there was
substantial market overconfidence, the early years in the period of interest show a smaller amount of
acquisitions than the more recent years. Especially Chinese investments grew considerably during this
study’s observed time period. In this research time trend is added to the model to control for movements in
the number of FDI M&As into the Eurozone developed over time that are not explained by the independent
variables in the model. This could be due to technological development, of the internet for example, which
increases the information availability or the increased open economy. Furthermore, monitoring costs
decreased and could influence foreign investing decisions. However, this is hard to measure and the time
trend captures this assumption.
Furthermore, time dummies for each year are included to absorb year-specific effects that are not
explained by the regressors. As mentioned before, this study’s data period includes multiple crises which
may or may not affect investor confidence. Additionally, certain unobserved tariff agreements or
implementation of tax regulations for example, can influence FDI M&A. Therefore, time dummies are
implemented in this model.

𝛽𝑆𝑀𝑃𝐼𝐺 𝑆𝑀𝑃𝐼𝐺𝑗𝑡 + 𝜆𝑡 + ∑ 𝜏𝑙 𝑇𝑙𝑇−1𝑙=1 + 𝜀𝑖𝑗𝑘𝑡 (5)
Where:
𝛼𝑖𝑘 = The intercept in Eurozone 𝑖 in industry 𝑘
𝛽𝑥 = The coefficient for independent variable 𝑥
𝜆 = The coefficient for the time trend 𝑡, increasing with equal steps
𝜏𝑙 = The coefficients for time dummies 𝑇𝑙
𝑇𝑙 = Time dummy, equal to 1 for the year evaluated 𝑙, zero elsewhere
𝜀𝑖𝑗𝑘𝑡 = The error term
If individual country or time specific effects do not exist, pooled OLS conducts consistent
coefficient estimates. However, if individual effects are not zero, specific characteristics that are not
captured in the regressors of the model may influence the core assumptions of OLS. This results in the
conclusion that the model is no longer the best unbiased linear estimator. Disturbances may have different
variances across different countries (heteroskedasticity) and are related to each other (autocorrelation).
Different panel data models examine these unobserved effects across countries and account for individual
heterogeneity. Wooldridge (2002) labels two different estimation methods, random effects estimation and
fixed effects estimation, to deal with these unobserved effects.
The fixed effects model controls for individual specific effects that are time invariant and
considered as part of the intercept. This model assumes the same slopes, constant variance across countries
and allows the fixed effect to be correlated with other regressors in the model. The fixed effects model is
designed to study causes of changes within an investor country and the use such a model could help to
determine the net effect of the regressors, since the estimated coefficients of the model are not biased by
omitted time-invariant characteristics. The fixed effect model is displayed in formula 6.
𝐹𝐷𝐼𝑀&𝐴𝑖𝑗𝑘𝑡 = (𝛼𝑖𝑘 + 𝑢𝑖𝑗𝑘) + 𝛽𝑙𝑛𝑅𝐸𝑅 𝑙𝑛𝑅𝐸𝑅𝑖𝑗𝑡 + 𝛽𝐷𝑜𝑚𝑀&𝐴 𝐷𝑜𝑚𝑀&𝐴𝑖𝑘𝑡 +

Where:
𝑢𝑖𝑗𝑘 = is a fixed effect specific to a country 𝑗 and industry 𝑘, not included in the other variables
𝜀𝑖𝑗𝑘𝑡 = The error term
A random effects model considers that the unobserved effects are not correlated with the regressors
in the model and estimates the error variance as country specific. Thus, the random effects model assumes
that differences among individuals arises from its individual specific error and not in their intercepts. The
random effects model has a composite error term, which contains the conventional error term and a random
intercept. Random variable 𝑢𝑖𝑗𝑘 measures the random deviation of each entity’s intercept term from the
‘global’ intercept term 𝛼𝑖𝑘 (Brooks, 2014, p. 536).
J.P. van Doorn 30
The random fixed effect model is displayed in formula 7.
𝐹𝐷𝐼𝑀&𝐴𝑖𝑗𝑘𝑡 = 𝛼𝑖𝑘 + 𝛽𝑙𝑛𝑅𝐸𝑅 𝑙𝑛𝑅𝐸𝑅𝑖𝑗𝑡 + 𝛽𝐷𝑜𝑚𝑀&𝐴 𝐷𝑜𝑚𝑀&𝐴𝑖𝑘𝑡 + 𝛽𝑅𝐺𝐷𝑃𝐺 𝑅𝐺𝐷𝑃𝐺𝑗𝑡 +
𝛽𝑆𝑀𝑃𝐼𝐺 𝑆𝑀𝑃𝐼𝐺𝑗𝑡 + 𝜆𝑡 + ∑ 𝜏𝑙 𝑇𝑙𝑇−1𝑙=1 + (𝑢𝑖𝑗𝑘 + 𝜀𝑖𝑗𝑘𝑡) (7)
Where:
𝑢𝑖𝑗𝑘 = is a random effect uncorrelated with the predictors and not included in the other variables
To test if fixed and/or random effects exist in the data and dismiss the OLS as unbiased linear
estimator, the assumption that individual effects are zero has to be rejected. An F-test is conducted to see if
fixed effects improve the goodness of fit of the model relative to the pooled OLS. Random effects are
examined by the Breusch-Pagan Lagrange Multiplier test (Breusch and Pagan, 1980). If in both tests, the
null hypothesis is not rejected, the pooled OLS is preferred. In the case of rejection of the hypotheses of
both tests, to decide whether to use fixed or random effects, a Hausman specification test (Hausman, 1978)
is conducted. This tests whether the unique 𝑢𝑖 errors, or between entity errors, are correlated with the
regressors in the model. The random effects assumes that the unobserved effects are uncorrelated with the
independent variables, while the fixed effects does not. If this assumption is wrong the random effects
model will be inconsistent and fixed effects model is the best fit. However, if there is no significant
difference between the two estimates, the random effects estimator is more efficient and thus the appropriate
choice.
Most of the comparable studies previously done, used annual frequency of data. Because of the
quarterly data available and limited observations when using annual data, this research measures the effects
of the variables at quarterly frequency. The model regression is done separately for the total dataset,
subdivision of non-manufacturing and manufacturing and for high and low R&D industries, to test if
Blonigen’s (1997) firm-specific asset theory holds for FDI into the Eurozone. To see the effects of the
independent variables on the amount of FDI M&As in the subdivided industries for the different investor
country specific, individual regressions are conducted.

4.1. First impression
To visually investigate the effect of a descending Euro value on the number of FDI acquisitions
into the Eurozone, a plot of the main independent and the dependent variable of this study is created. Figure
2 shows the scatter plots of the dependent variable, number of FDI M&As into the Eurozone, and the logged
real exchange rate, for every investor country of interest in this study. The red trend line or line of best fit
in the subfigures, shows an initial upward slope for the Australian (panel A), Canadian (panel B), Chinese
(panel C) and United Kingdom-based (panel E) investors. This can be interpreted as a potential positive
relationship between a higher logged exchange rate, which means more Euro per foreign currency, and the
amount of incoming FDI into the Eurozone from these foreign investors. However, subfigures for Japan
(panel D) and the United States (panel F) show a downward line, so no clear unanimous relationship is
examined. In addition, the scatterplots show some considerable deviation from the line of best fit, which
might be problematic for the significance in the analysis of this study. Comprehensive statistical analysis
could provide more evidence on the relationship, taking into consideration the independent explanatory and
control variables.
4.2. Statistical soundness
As mentioned in the previous chapter, the statistical soundness of the model has to be investigated
before turning to the regression model. The potential problems will be discussed in this section.
To investigate the presence of autocorrelation: the interdependence between the error terms, a
Wooldridge test for autocorrelation in panel data (Wooldridge, 2002) is performed on the data of this study.
Table A.2. in the Appendix presents the results of this test for each industry subdivision. The null hypothesis
of the test of no autocorrelation is rejected on at least a 0.05 significance level for all parts and for all
industries, manufacturing and high R&D industries even at 0.01 significance level. Therefore, it can be
concluded that there is a presence of autocorrelation among the error terms in the dataset.
The second statistical problem to be investigated is heteroskedasticity. Table A.3. of the Appendix
contains the results of the Likelihood-ratio test for heteroskedasticity for each industry subdivision, where
the null hypothesis of the test is homoskedasticity of the error terms.13 The null hypothesis is strongly
rejected for all parts, indicating that there is indeed heteroskedasticity and errors are not identically
distributed for all industries.
13 The modified Wald test for heteroskedasticity in fixed effects model is not included in this research because a
random effects estimation model is used in this study and the Wald test cannot be used in the case of random effects
model estimation. The Hausman specification test (Hausman, 1978) presented later on in this chapter will support this
choice.
J.P. van Doorn 33
The first two statistical problems discussed, the presence of autocorrelation and heteroskedasticity,
influence the standard errors of the model. To ensure the unbiasedness of the test statistics and standard
error estimates are robust to disturbances of both problems, Rogers clustered robust standard errors are used
as explained by Hoechle (2007, p.4). The panel identifier “investor country” is the cluster variable that
makes the Rogers standard errors heteroskedasticity and autocorrelation consistent.
The potential existence of multicollinearity is first monitored by looking at the correlation matrices
of Table A.4. in the Appendix. These matrices show per part, the correlation between the five main variables
in this study for each industry. The positive significant correlation between the real exchange rate and FDI
M&As in each part gently confirms the expected positive relationship between the two variables. However,
the correlation coefficient is not extremely high. Surprisingly the real GDP growth variable and FDI show
a significant negative correlation coefficient. In addition, the real GDP growth variable is significantly and
positively correlated with the stock market price index growth, which is in line with expectations. The other
independent variables however, show no fierce and/or significant correlation with each other and it is
therefore unlikely that a large multicollinearity problem will occur.
To formally investigate the presence of multicollinearity, Table A.5. presents the VIFs of the
independent explanatory variables in the regression model. The VIF measures how much the variance of
the regression coefficients estimated in the model, are inflated because of linear dependence with other
independent variables. O’brien (2007) discusses the VIF examines the rules of thumb with respect to the
cut-off values, which vary significantly between studies. A common but strict rule of thumb is a cut-off
value of 4. Analyzing the results of the VIF matrices, show that there are no major differences in VIFs for
the variables among the different industry parts of Table A.5. The Eurozone domestic acquisitions variable
has the highest VIF, which takes values between 2.02 in non-manufacturing industries (part B) and 2.05 in
manufacturing (part C) and High R&D (part D) industries. The values for the remaining explanatory
variables fluctuate between 1.08 and 1.67, indicating no excessive multicollinearity problem in the study’s
model and no variables have to be excluded.
4.3. Panel regression model
The next step is to determine the appropriate regression methodology for this research. As
mentioned in the previous chapter, starting position shall be the pooled OLS. Because unobserved effects
are likely to influence the number of FDI M&As in this study, tests are conducted to see if the fixed effects
or random effects regression give a better estimation of the relationship between the variables.
Table A.6. contains the F-test for each industry subdivision, which tests the null hypothesis that the
unobserved fixed effects are equal to zero. For every industry the null hypothesis is strongly rejected,
indicating that the fixed effects model is a better estimator than the simple pooled OLS. Table A.7. presents
J.P. van Doorn 34
the results of the Breusch-Pagan Lagrange Multiplier test. The null hypothesis of the LM test is that that
the variances across entities are equal to zero. Since that hypothesis is also strongly rejected for all industries
and it can be concluded that variances across entities are significantly non-zero, it is clear that the random
effects model is preferred relative to the pooled OLS model.
Previous findings suggest that both the fixed effects and random effects model are a better
estimation model for this study’s dataset compared to the pooled OLS. To formally test which estimation
method fits best, a Hausman specification test is conducted. The null hypothesis is that individual effects
are not correlated with other regressors in the model. If this hypothesis is rejected, a fixed effect model is
recommended instead of the random effects. If this hypothesis is not rejected, the random effects model is
the consistent and efficient estimation method. Table A.8. presents the results of the Hausman specification
test for each industry. The null hypothesis cannot be rejected in any of the industries, so the random effects
estimation is the appropriate choice for this research.
4.4. Determinants of foreign direct investment into the Eurozone
This section analyzes the regression results of the independent variables mentioned in the previous
chapters, on FDI M&As into the Eurozone of all considered investor countries in the time period 1999Q1
to 2016Q2. Table 4 presents the regression results and shows the estimates of the determinants of for each
specification, where industries are subdivided. The results obtained from the estimation model and effects
of the independent explanatory variables are briefly considered.
The main explanatory variable and regressor of interest in this study, the real exchange rate, does
not have a statistically significant effect in either of the specifications. Even though, the expected positive
sign of the coefficient is displayed, because of high standard errors no interpretation of the relationship can
be made.
Domestic acquisitions in the Eurozone show a positive and weakly significant effect in the all
industry, non-manufacturing and low R&D specifications. While significant, the economic magnitude is
limited; if the variable Eurozone domestic acquisitions increases with one standard deviation (165.153) in
the all industries specification, the number of FDI M&As increase with 2.312.
In the manufacturing industry specification, investor real GDP growth has a positive and weak
significant coefficient. One standard deviation increase in the Real GDP growth variable (0.010), results in
an increase of 0.506 FDI acquisitions into the Eurozone.

In both the all industry and non-manufacturing specification, the Stock market price index growth
variable shows a negative coefficient at the 0.1 significance level. The economic magnitude of this
coefficient shows that if stock market price index grows one standard deviation (0.096), the dependent
variable of this study decreases with 0.721 for non-manufacturing industries.
The time trend coefficient in this regression is only significant for the high R&D specification in
this regression, while the constant is significant for all the industries subdivisions.
Table 4
Regression Results – Determinants of FDI M&A into the Eurozone
Table 4 presents the regression results of the explanatory and control variables on the number of FDI M&As into
the Eurozone with the random effects model (7) defined in chapter 3. The table contains the estimations for the
separate defined subdivided industries. All variables are constructed by using quarterly data from 1999Q1 to
2016Q2. All regressions are obtained with the xtreg command with random effects, using Stata. Rogers clustered
standard errors are included in parentheses. ***, ** and * show the level of significance of 0.01, 0.05 and 0.1
respectively. Estimates are rounded to 3 decimals.
Note: SIC codes between 2000 and 3999 are manufacturing industries, all other are non-manufacturing industries.
High R&D industries are SIC 2810-2899, 3510-3599, 3650-3679, 3710-3729, 3760-3769 and 3810-3899. Low

J.P. van Doorn 36
Sigma_e represents the standard deviation of the overall error term 𝜀𝑖, while Sigma_u shows the
standard deviation of the residuals between the panels 𝑢𝑖. For every specification except low R&D, the
standard deviation of 𝑢𝑖 is higher. Rho shows the ratio of variance due to individual specific error variance
to the complete composite error variance in the model and may be interpreted as a goodness-of-fit indicator.
The high rho in all the specifications indicates that individual specific errors accounts for a large proportion
of the composite error variance.
The random effects estimator used in this study is a matrix weighted average of the estimates
produced by the between and within estimators. None of the R² estimates shown in the output, corresponds
directly to the relevant R². Therefore, Theta (𝜃) is added as an additional measure of goodness-of-fit. “Theta
is a function of 𝜎𝑢2 and 𝜎𝜀
2 . If 𝜎𝑢2 = 0, meaning that 𝑢𝑖 is always 0, 𝜃 = 0 and the relationship can be
estimated by OLS directly. Alternatively, if 𝜎𝜀2 = 0, meaning that 𝜀𝑖 is 0, 𝜃 = 1 and the within estimator
returns all the information available”. (StataCorp LP, 2015, p. 403) The high theta in all specifications,
indicates that there is indeed a considerable amount of variation in the model because of variation in 𝑢𝑖.
4.5. Investor country-specific determinants of FDI into the Eurozone
Previous section discussed the effect of the independent variables on the number of FDI
acquisitions into the Eurozone for all top investor countries. The observed overall relationship might
however be blurred by investor countries that show deviating or abnormal values. As mentioned in chapter
2, Lee (2013) finds that the suggested link between exchange rate level and the asset-seeking acquisition
FDI can only be confirmed for U.S. inbound acquisitions. When U.S. data is excluded, no support for the
hypothesis could not be found. To test the regressors on the investor country specific level, regressions are
run for each individual top investor country. Since the analysis is no longer on a panel dataset, OLS
regressions are performed. This section discusses the regression results of the country specific data in each
industry. In order to better interpret the outcome of the regressions, the mean and standard deviation of the
variables on investor country level are presented in table A.9. in the Appendix. Since not all investor country
regressions show admissible significant results, the less relevant output is located in the appendix. Table 5
presents the regression results of the investor countries; Canada, Japan and the United States and are briefly
considered.
The real exchange rate has a positive and significant effect on the number of Canadian FDI
acquisitions in the manufacturing (0.05 significance level) and high R&D (0.01 significance level)
industries. Because of the logarithmic modification of the independent variable, the interpretation is
different than other variables. If the variable logged real exchange rate increases with one percent, the
number of Canadian FDI M&As in Eurozone increases with 0.11949 for high R&D industries.
J.P. van Doorn 37
While the real exchange rate in the Canadian panel shows a positive relationship, the Japanese and
United States panel show significant negative signs in some specifications. In the non-manufacturing
industries, one percent increase of the logged real exchange rate decreases the number of Japanese FDI with
0.083 Japan and US acquisitions with 0.805.
The variable Eurozone domestic acquisitions shows a significant negative sign in the Canadian
high R&D panel, while positive in the Japanese manufacturing and all industry specification of the U.S.
panel. However, the economic magnitude is not large; if the all industry Eurozone domestic acquisitions
variable increases with one standard deviation (166.148), the number of U.S. FDI into the Eurozone
increases with 5.815.

The United States real GDP growth appears to have a (weak) significant positive effect on the
amount of low R&D industry acquisitions in the Eurozone by bidders with a registered office in the U.S.
When the real GDP growth variable increases with one standard deviation (0.006), the number of United
States’ FDI M&As into the Eurozone increases with 1.007.
In the manufacturing industry specification, the stock market price index growth variable appears
to have a statistically significant negative effect on incoming Japanese FDI in the Eurozone. One standard
deviation (0.103) increase of the independent variable, depreciates the number of acquisitions with 0.605.
Time trend is not significant in any of the specifications of the investor countries. The constant on
the other hand appears to be significant and positive for the United States’ panel, but shows no unanimous
outcomes across the Canadian and Japanese regression results. The F-test in the regression output tests
whether the coefficients on the regressors in the model are all jointly non-zero. F-tests of the estimators in
the Japanese panel are all significant and indicate adequate models. Finally, also the within R² is presented
below the coefficient section. While the regressions on the complete panel dataset, none of the R² give the
appropriate measure, in this case the within estimator gives the correct estimation. The subdivision of the
panel data into investor countries neutralizes the panel nature of the date, without random effects, allowing
the within estimator to present an interpretable R². The R² shows the portion variable variation that is
explained by the linear model in all specifications. While in some specifications the estimator takes
considerable large values, there are specifications across countries where the model shows moderate
explanation which might be caused by the small amount of observations available.

5. Discussion
5.1. Hypotheses testing and interpretation
The empirical results presented in chapter 4 of this study, are used to test the hypotheses formulated
in chapter 2. Each hypothesis is discussed in detail, the findings are interpreted and compared with previous
research and the current state of literature.
Hypothesis 1: A depreciation (appreciation) of the Euro, increases (decreases) the number of incoming
FDI acquisitions into the Eurozone
While scatter plots for multiple investor countries would suggest a positive relationship, Table 4
presents the coefficient of the logged real exchange rate which seems to have no significant effect in any
of the specifications in the complete investor countries’ regression. Coefficients show a positive sign, but
because of high standard errors no interpretation of the relationship can be made. In addition, Table 5 panel
B shows analyses for the Eurozone acquisitions of the U.S. firms, where the coefficient in multiple industry
specifications has a significantly negative sign. These results are line with Lee (2013), who finds that the
enhancing effect of a devaluating domestic currency on the amount of FDI, is mainly driven by U.S.
inbound acquisitions. The United States market is probably more open to foreign firms and is most likely
the leading marketplace for innovation and technology in the world. Even though the Eurozone contains
multiple well-developed countries, the U.S. is considered to be the vanguard in technological development.
The significant negative coefficients in the U.S. panel (C) seem to indicate that a devaluating Euro only
negatively affects Euro denominated profits for the U.S. firms, while no real high-value technological assets
can be acquired that provide value without the need of additional exchange rate exposure. Hypothesis 1 is
therefore rejected for U.S. acquisitions in the Eurozone.
Table 5 panel A however, displays a positive significant effect of the real exchange on the number
of Canadian FDI acquisitions in the manufacturing and high R&D industries. Although not for every
industry subdivision the coefficient is significant, this result seems consistent with an extensive number of
studies on this relationship (e.g. Blonigen, 1997; Frood & Stein, 1991). Hence the hypothesis cannot be
rejected for the Canadian data, meaning that Canadian incentive for FDI acquisitions in the Eurozone is
positively influenced by the decreasing value of the Euro in the manufacturing and high R&D industries.
Hypothesis 2: Higher (lower) number of domestic acquisitions, increases (decreases) the number of
incoming FDI acquisitions into the Eurozone
The total FDI M&A into the Eurozone analysis of Table 4, reveals a positive effect of number of
domestic acquisitions on the amount of foreign incoming acquisitions for all specifications except
manufacturing and high R&D industries. In addition, the Japanese manufacturing and U.S.’ all industry
J.P. van Doorn 41
specification show a positive and significant coefficient in panel B and panel A of Table 5 respectively.
Coefficients derived from this research, confirm previous findings of Blonigen (1997) and Georgopoulos
(2008) of domestic acquisitions as proxy accounting for M&A supply. It should be noted however, that
Canadian analysis shows a negative sign for its high R&D specification.
Although the economic magnitude seems limited, an active domestic M&A environment boosts
the number of FDI acquisitions for the overall, non-manufacturing and low R&D industries and for
Japanese acquirers, in the manufacturing industry. Conclusively, the hypothesis cannot be rejected, for the
mentioned industry and investor country specifications.
Hypothesis 3: Higher (lower) foreign GDP growth rates, increases (decreases) the number of incoming
FDI acquisitions into the Eurozone
The manufacturing specification of Table 4 shows a positive relationship between investor real
GDP growth and the amount of FDI into the Eurozone. In addition, the United States real GDP growth
appears to confirm the positive relationship between these factors in the low R&D industry specification of
Table 5 panel C. Di Giovanni (2005) and Blonigen (1997) findings are confirmed in this research for these
specifications. The supply control variable accounts for economic growth of the investor country, which
should positively influence the demand of foreign investors for FDI in the Eurozone. Although not
unanimously for all specifications, the positive effect found is significant for the manufacturing industry
for all investors and in low R&D industries for the U.S. Therefore, the hypothesis cannot be rejected for
the mentioned specifications.
Hypothesis 4: Higher (lower) growth rate of the acquirer’s stock market price index increases
(decreases) the number of incoming FDI acquisitions into the Eurozone
Table 4 presents in both the all industries and non-manufacturing specification, a negative effect of
the acquirer’s main stock market price index growth and amount of FDI M&As into the Eurozone. In
addition, Japanese incoming FDI is also negatively influenced by an increase in stock market price index
growth for the manufacturing specification. Interestingly, findings of this study contradict research findings
and assumptions of Frood and Stein (1991) and Blonigen (1997) for certain specifications. They expect a
flourishing stock market to increase wealth of the potential acquirer and enhance demand for FDI. Instead
of the positive relationship, a significant negative effect is found in this study. Therefore, the hypothesis is
rejected for the all industry, and non-manufacturing specification of all investors analysis and for Japanese
acquisitions in the manufacturing industry. Since the significant negative effect is especially seen in the all
industry and non-manufacturing markets, a possible explanation might be that foreign investors prefer to
invest their wealth in a bullish domestic market instead of acquiring assets abroad.
J.P. van Doorn 42
Hypothesis 5: The effect of a depreciating (appreciating) Euro on the number of incoming FDI
acquisitions, is more positive (negative) for manufacturing industries than non-manufacturing industries
As mentioned before, the real exchange rate shows no significant effect in the complete all investor
regression. Table 5 panel A however, does only show a significant relationship between the real exchange
rate and FDI for the manufacturing industry specification. This means that the real exchange rate does not
influence the number of FDI M&A in non-manufacturing industries and therefore it seems confirmed that
a depreciating Euro has a more positive effect on FDI in manufacturing than non-manufacturing industries.
Thus, hypothesis 5 cannot be rejected for Canadian acquisitions in the Eurozone. This provides support for
among others, Froot and Stein’s (1991) and Blonigen’s (1997) findings, that acquiring manufacturing firms
is beneficial when the Euro devaluates.
However, analyses on Japanese and United States’ data show no significant effect in the
manufacturing specifications, while a significantly negative coefficient for the non-manufacturing
industries. Because in the mentioned specifications, the relationship is negative for non-manufacturing
industries while there is no significant influence on manufacturing acquisitions, here too the hypothesis
cannot be rejected.
Hypothesis 6: The effect of a depreciating (appreciating) Euro on the number of incoming FDI
acquisitions, is more positive (negative) for high R&D manufacturing industries than low R&D
manufacturing industries
To test if Blonigen’s (1997) firm-specific asset theory holds, effects in high and low R&D
manufacturing industries are compared. Analyses of determinants of Canadian FDI in the Eurozone show
an insignificant coefficient in low R&D industries while a highly significant positive relationship for high
R&D industries. This is consistent with the findings of Georgopoulos’ (2008) and Lee’s (2013) concerning
the firm-specific asset theory. The hypothesis can therefore not be rejected for the Canadian acquisitions.
Thus, Blonigen’s (1997) theory on acquiring high technology firms seems to be confirmed for the Canadian
FDI into the Eurozone.
However, it should be noted that the complete manufacturing specification shows a larger positive
(but less significant) coefficient than for high R&D industries, which slightly contradicts the theory behind
acquiring high technology assets more cheaply.
5.2. Implications
The previous section interpreted the results of this study and briefly compared the outcome with
the current state of literature on the subject. This section discusses the potential useful implications of this
research for different relevant practitioners. To determine the academic, theoretical and practical
J.P. van Doorn 43
implication of this study, the main results of both the multiple investors analysis and investor country
specific are compared and examined with previous findings in existing literature.
The empirical section of this research examines effects of determinants of foreign direct
investments M&A into the Eurozone. Main determinant of interest, the real exchange rate, seems to have
no significant effect in the specification of all investor countries combined. This is similar to the findings
of Lee (2013), who argues that the overall effect found by Blonigen (1997) is likely more U.S. data bound.
In addition, the number of domestic acquisitions seems to demonstrate a positive M&A environment,
attracting FDI as the literature prescribed. However, foreign stock market growth seems to have a negative
effect on the number of incoming FDI in the all industry and non-manufacturing specification. This might
be explained by that foreign investors prefer to invest their wealth in a bullish domestic market instead of
acquiring foreign non-manufacturing assets that do not have any potential technological value. One
interesting additional observation is that there seems to exist a time trend in the overall high R&D industries,
which seems to indicate that more and more high tech companies in the Eurozone are acquired by foreign
firms.
Subsequently, the determinants are analyzed on investor country-specific level to determine
specific investor country effects on the determinants. The main variable of interest, the real exchange rate
shows a significant and positive effect in the manufacturing and high R&D specifications for Canadian FDI.
The positive effect on high R&D industry acquisitions, and no significant effect in non-manufacturing and
low R&D industries, imply that Blonigen’s (1997) firm-specific asset theory can be confirmed for Canadian
investment in the Eurozone. However, the opposite effect is found for the U.S. investors. Depreciation of
the Euro has a negative effect on the U.S. acquisitions in the total industries, non-manufacturing and high
R&D industries. Again, this seems to confirm Lee’s (2013) claim of U.S. inbound specific.
Altogether, empirical results found in this study provide support for interesting areas of future
research. Even though not one determinant had a significant effect in all specifications across all countries,
it seems that the real exchange rate does influence the number of FDI and even confirms the asset acquiring
theory for Canada. Furthermore, an interesting area of future research could be, describing the negative
effect of the investor country’s stock market on the amount of FDI found. In addition, the analysis of
Chinese data did not give great significant results, while the scatter plot showed an upward sloping line and
the Chinese Yuan increased in value compared to the Euro in recent years. Absence of empirical evidence
on this expected relationship, while the amount of incoming Chinese acquisitions increased significantly,
could be explained by their recent investment appetite compared to a low amount of deals in the early period
of date sample investigated in this study (Table A.1 of the Appendix). Future research could investigate the
effect on a shifted time period.
J.P. van Doorn 44
As stated above and in chapter 4 of this study, evidence for the firm-specific asset theory for
Canadian investors is provided. Finding a positive effect of the depreciating Euro on FDI incentive for
certain countries, alongside domestic acquisitions and GDP growth for some industries, could be valuable
information for business owners and M&A advisors. Findings help professionals understand differences in
M&A incentive across investing countries and help in the search of a potential foreign buyer when
analyzing the determinants applicable to specific countries. In addition, the depreciating Euro might yield
a higher bidding price in negotiations with a foreign bidder compared to a domestic one because of the
higher relative wealth, or high-tech firm-specific assets which are more valuable to the foreign firm. Finally,
the results help understand what can drive short-term mergers and acquisitions fluctuations and predict
future flows.
5.3. Limitations
Several limitations of research have to be acknowledged. This empirical study relies on the
availability of data. The first limitation is that only the occurrence of a deal is included because deal value
is often not public information and omitted. In addition, this data dependence also means that undisclosed
deals due to unavailability or measurement error can occur because of for example secret data from certain
less open economies. Secondly, M&A is more common in the United States market, which provides more
data available compared to European countries. This makes it harder to find effects of the determinants.
Thirdly, in the case of a merger, there is no real acquiring firm. This problem is not dealt with in this
research since the dataset always provides a target and an acquiring firm. Di Giovanni (2005) notes the
same problem but states that what often is announced as a merger, afterward turns out to be an acquisition.
Fourth issue is the cut-off value of 10% ownership stake after transaction to count as true FDI. This research
uses the threshold established by the OECD, but there are cases where less than 10% of company’s voting
shares established effective ownership. This assumption limits the number of (FDI) M&As taken into the
M&A variables of this study. Fifth, the choice of the specific investor countries also influenced the study,
just like the assumption to use the first initial Eurozone countries. The Eurozone countries examined are a
diverse mix of multiple countries, which are in principle considerably well developed and seem open
economies because of the Euro, but may differ significantly in technological advancement and business
operation. The final limitation is briefly discussed in section 2.6; omitted factors. Introduction of new taxes,
tariffs or other economical protection methods for example, may influence FDI decisions but are not
available on this level of data disaggregation. But also elections, the Brexit or determinants that are not
investigated, might have an impact. Further investigation could reveal new effects of certain new elements
of explanation.
J.P. van Doorn 45
6. Conclusion
The increasing amount of Eurozone firms acquired by foreign firms in recent year, accompanied
by a decreasing Euro, attracted attention. Dissension in empirical findings of previous literature on the link
between currency exchange rate and cross-border FDI, which is mainly U.S. bound, is the rationale for new
research on this relationship. In search for an explanation that clarifies short-run M&A fluctuations, this
study examines the link between the real exchange rate and FDI M&A into the Eurozone by using quarterly
data between the introduction of the euro on 4 January 1999 and 30 June 2016. To investigate if Blonigen’s
(1997) firm-specific asset acquisition theory may apply to the Eurozone, a subdivision between
(non-)manufacturing and high R&D and low R&D industries is made in the empirical analysis. In addition,
other potential determinants mentioned in relevant literature are included in the model to account for supply
and demand of cross-border M&As.
To investigate if a decreasing Euro value positively affects the number of FDI acquisitions into the
Eurozone, this study first analyzes the top 6 investing countries outside of the Eurozone. Results of this
analysis provide no clear evidence for a positive effect of the real exchange rate when examining all investor
countries combined. However, the output shows that Eurozone domestic acquisitions and investor country’s
real GDP growth, positively affect the number of incoming FDI in multiple industries. In contrast to the
predicted relationship by previous literature, investor stock market price index growth seems to have a
significant negative effect on FDI acquisitions. This might indicate that in a bullish stock market, investor
firms prefer to put their wealth in domestic investments rather than acquiring foreign assets.
These results confirm previous findings of Lee (2013), who states that the effects found of a
devaluating domestic currency on the amount of FDI, is mainly driven by U.S. inbound M&A data. When
he excludes the U.S. data and only inbound acquisition FDI into other foreign countries are considered,
support for the hypothesis could not be found. This might sound feasible since the U.S. spend the most on
R&D and are considered the birth nation of many high-tech innovations. Another explanation might be that
the U.S. market is more open to FDI investments.
To shed a light on if the relationship might be investor country specific, results per investor country
are presented. Although, for some countries no real significant effect of any determinants can be found,
Canadian, Japanese and U.S. data show interesting results. A depreciating Euro has a strong significant
positive effect on the number of Canadian acquisitions in the Eurozone in the high R&D industry, while no
significant effect in the low R&D specification. Therefore the Canadian data seems to confirm Blonigen’s
(1997) theory of high-tech assets that are acquired more cheaply and generate returns that are not necessarily
denominated in the target currency, but for example increase efficiency of the acquirer’s plant. However,
the U.S. panel shows a (weak) significant negative relationship in the high R&D specification, so the effect
indeed appears to be country specific.

Variance Inflation Factor
Table A.5. presents the Variance Inflation Factor matrices of the independent explanatory variables in the
regression to formally test for multicollinearity. Variance Inflation Factors measure how much the variance of the
regression coefficients estimated in the model, are inflated because of the linear dependence with other
independent variables. Each part describes the VIFs in a different industry. The dependent variable is the number
of FDI M&A into the Eurozone in each industry and the independent variables are the logged real exchange rate,
Eurozone domestic acquisitions in each industry, investor country real GDP growth and investor country stock
market growth. All variables are constructed by using quarterly data from 1999Q1 to 2016Q2. Estimates are
rounded to 4 decimals.
Note: SIC codes between 2000 and 3999 are manufacturing industries, all other are non-manufacturing industries.
High R&D industries are SIC 2810-2899, 3510-3599, 3650-3679, 3710-3729, 3760-3769 and 3810-3899. Low
