Abstract
Tail risk is a risk factor that investors consider when making investment decisions. This paper
empirically tests the role of tail risk in international market. I find evidence that tail risks are
priced using sample of 40 countries from 1980 to 2014. Across all countries, investors require
lower rate of return to hold asset which are a better hedge to the tail risk. Pricing of tail risk
varies across different countries with different level of integrations into the global financial
market. In addition, I show that tail risk act as a global transmission channel of contagion during
crisis. The findings provide implications for international portfolio diversification as well as
understanding the role of tail risk in asset prices on international financial markets and during the
financial crisis.

A Previously Ignored Risk Factor in International Markets: Tail Risk
Abstract

Tail risk, defined as extreme event risk in asset markets, is an important aspect for investor to
consider when making investment decisions. Recently, various theoretical models have
incorporated the tail risk and shown that heavy-tailed shocks to economic fundamentals help
explain asset pricing behavior (Rietz 1988; Barro 2006; Gabaix 2012; Gourio 2012; Wachter
2013; Bansal and Yaron 2004; Eraker and Shaliastovich 2008; Bansal and Shaliastovich 2010;
Bansal and Shaliastovich 2011; Drechsler and Yaron 2011). Empirically, Bollerslev and Todorov
(2011) find that the compensation for extreme events accounts for a large fraction of US equity
risk premium. Jiang and Kelly (2014) show that tail risk has strong predictive power for
aggregate market returns and also has significant predictive power for cross-section of average
asset returns in the US markets.
Overall, the existing literature provides some supporting evidence in US market that investors
are tail risk averse and require higher return to hold tail risky assets. However, while it is
important to investigate tail risk in international financial markets, there is little empirical
evidence showing tail risk is a globally priced risk factor. Using global markets for the
investigation in tail risk is crucial as the importance of tail risk could be more pronounced in
markets other than US, where tail risk is allegedly high, while the importance of tail risk could
be less pronounced in some markets where tail risk is low. On the other hand, it would also be
possible that tail risk is not important in some markets, unlike the results found in US market.
Hence, extending the study of tail risk to world markets could provide a good opportunity to
evaluate and understand the role of tail risk as a possible source of global systematic risk.
In addition, different countries have different level of integration into the global financial market,
thus the importance of global and local specific tail risk could be different across countries. For
investors in countries with high integration into the global financial market, they might concern
more about global tail risk instead of local specific tail risk. As a result, global tail risk could
have bigger impact on investment decisions than local specific tail risk. On the other hand,
investors from countries with low integration into the global financial market might care more
about local specific tail risk instead of global tail risk when they make investment decisions.

Therefore, using global market makes it possible to investigate such cross-country or cross-
regional variations in the pricing of tail risk, and provide excellent out-of-sample test outside of
US.
Most importantly, extreme events are not restricted to US market, developed markets, or
emerging markets, but they can occur worldwide, making it necessary to investigate all financial
markets together. In addition, during financial crisis, extreme events are more likely to occur in
multiple countries, making it especially important to use international markets to study and
understand the role of tail risk during the period.
In this paper, I examine the role of tail risk, as being a global risk factor, in international
financial markets by using around 60 thousand stocks from 40 countries from January 1980 to
December 2014. I also examine in details about the role of tail risk during the global financial
crisis happened in 2007 and 2009. The crisis started initially in a relatively small segment of the
lending market, the subprime mortgage market, in the United States, then it spreads rapidly and
violently across all economies in the world, both developed and developing, as well as across
economic sectors. During the crisis, equity markets worldwide are affected and the extreme
events happen more frequently than normal period. Many countries experiencing even sharper
equity market crashes than the United States. After the crisis, researchers try to understand how
and why the crisis in a small sector in US has spread so violently and transformed into a global
financial crisis. There are various papers suggesting the possible sources of contagion such as
transmission through banking exposure channel (Kaminsky and Reinhart (2000), Van
Rijckeghem and Weder (2001), Caramazza, Ricci, and Salgano (2004), and Tong and Wei (2010,
2011)), banking policy channel (King (2009)), external exposure/segmentation channel
(Mendoza and Quadrini (2010), Briere, Chapelle, and Szafarz (2012), Fratzscher (2012)),
information asymmetries channel (Albuquerque, Bauer, and Schneider (2009), and Dumas,
Lewis, and Osambela (2011)), domestic macroeconomic fundamentals channel (Ahnert and
Bertsch (2013)), and global/common risk and liquidity channel (Bekaert et al. (2011) and Baker,
Wurgler, and Yuan (2012)).

Although many studies have been done to understand the 2008 financial crisis, little studies ever
investigate the role of tail risk during the time, while it is the perfect time to check how tail risk
impacts asset prices. During the crisis, investors might care more about tail risk as extreme
events can occur more frequently as firms tend to fail together. As a result, examining tail risk’s
role during financial crisis becomes crucial to deepen our understanding about the 2008 global
financial crisis. I contribute to the literature as the first paper that empirically analyzing the role
of tail risk in asset prices during the financial crisis on international financial markets.
Previously the chief obstacle to investigate the effects of time-varying extreme event risk in asset
markets was a viable measure of tail risk over time. There are three current approaches to
measuring tail risk dynamics for stock returns: one based on option price data, one on high
frequency return data, and the other on panel return data. Examples of the option-based approach
include Bakshi, Kapadia, and Madan (2003), who study risk-neutral skewness and kurtosis;
Bollerslev, Tauchen, and Zhou (2009), who examine how the variance risk premium relates to
the equity premium; and Backus, Chernov, and Martin (2011) and Gao and Song (2013), who
infer disaster risk premium from options. Tail estimate from high-frequency data is exemplified
by Bollerslev and Todorov (2011). Panel estimation approach using daily return data is proposed
by Jiang and Kelly (2014), who investigate the effects of time-varying extreme event risk in US
market. All three approaches are powerful but the first two are subject to data limitations. The
third approach can provide a time series of tail risk estimates as long as a large cross-section data
is available, which allows me to construct tail risk estimates for most of the important stock
markets around the world.
In this paper, I examine tail risk as a globally priced risk factor in international asset pricing and
provide empirical evidence that tail risk is a risk that investors are averse to, and it is priced
internationally. In details, I first construct tail risk estimates for each country using stocks daily
return data, and examine the characteristics of tail risks. If tail risk is a risk factor, then investors
shall be averse to it and require high return to hold tail risky assets and portfolios. As a result,
contemporaneously, tail risk should be positively correlated with aggregate market return as
6
investors are tail risk averse and market is subject to its tail risk. In addition, I found that time-
varying tail exponent is highly persistent in some countries such as US, with AR(1) above 0.7.
Therefore, I expect that in these countries, tail risk estimates should have strong predictive power
for future extreme returns of individual stocks as investors might use it to predict future level of
tail risk. To better distinguish the impact of tail risk from global part and local specific part in
each country, I construct global tail risk as the value weighted countries’ tail risk, and local
specific tail risk as the orthogonalized part of country tail risk with respect to global tail risk. I
test weather tail risk is correlated or can forecast aggregate stock market returns using different
types of tail risks constructed. Consistent with expectations that investors are averse to tail risk
and require high return to hold tail risky assets and portfolios, contemporaneous regressions
show that all tail risk measures are positively and significantly correlated with market aggregate
return. Nevertheless, predictive regressions also show that all tail risk measures used can
significantly and positively predict future market return in most of the countries, consistent with
expectations, at the one month and one year horizons.
Next, I test whether assets that better hedge tail risk command a relatively high price and earn
low expected returns. In each country, I estimate individual stock’s sensitivity to tail risk using
past 60 month rolling window, and then form portfolios based stocks’ sensitivities. Among
around 20 countries which account for more than 70% of total market weight, portfolios with
high sensitivity earn significantly higher returns than portfolios with low sensitivity.
Then I empirically examine whether tail risks are significantly priced in international financial
markets, controlling for other risks. I also investigate which type of tail risks is significant in
pricing (global/local tail risk), and in which type of countries that tail risk has significant price. I
employ a cross-sectional regression framework and factor model regressions to investigate this
issue. Overall, in most of the countries (around 30), global tail risk has significant and positive
price, while corresponding local tail risk are only significant in 11 countries, most of which are
classified by MSCI as emerging markets. In addition, global tail risk is shown to be more
important than local tail risk in countries with high integration into the global financial market,
7
which are more open, and more developed countries. On the other hand, local tail risk is more
important in countries with low integration into the global financial markets, which are less open,
and less developed countries.
After showing that global tail risk is a globally price risk factor, I then empirically examine the
role of tail risk during a special time period – 2007 to 2009 financial crisis. I show that tail risk
affects investors’ risk aversion, thus during crisis time, when tail risk is high, investors shun
away risky assets and fly to safety. Following the setting in Bakaert, Ehrmann, Fratzscher, and
Mehl (2014), I found evidence suggesting that tail risk plays an important part in the spread of
financial crisis by testing whether and how the dependence of factor exposures on tail risk
changed during the crisis. The results suggest that tail risk is a possible source of contagion
during 2007-2009 financial crisis though the global/common risk channel.
My findings contribute to several strands of literatures. Researchers have hypothesized that
heavy-tailed shocks to economic fundamentals help explain certain asset pricing behavior that
has proved otherwise difficult to reconcile with traditional macro-finance theory. Examples
include the Rietz (1988) and Barro (2006) rare disaster hypothesis and its extensions to dynamic
setting by Gabaix (2012), Gourio (2012), and Wachter (2013), as well as extensions of Bansal
and Yaron’s (2004) long-run risks model that incorporate fat-tailed endowment shocks (Eraker
and Shaliastovich 2008; Bansal and Shaliastovich 2010, 2011; Drechsler and Yaron 2011). Using
tail risk constructed using method from Jiang and Kelly (2014), mine is the first paper to directly
document time-varying tail risks worldwide, show tail risk is significantly priced internationally,
and provide evidence consistent with two key equity premium implications from above models.
In addition, using international sample helps better investigate tail risk as a globally priced risk
factor and provide more comprehensive out-of-sample test than just examining US markets alone.
It also helps to better understand the cross-country variation of tail risk’s impact on investors’
investment decisions, which depends on the level of integration of local market into the global
financial market. Overall, I show that investors are tail risk averse, increases in tail risk raise the
return required by investors to hold the tail risky assets, such as aggregate market returns. I also
8
show that tail risk affect cross-section of expected returns. High tail risk is associated with bad
states of the world and high marginal utility. Hence, assets that hedge tail risk are more valuable
and have lower expected returns than those that are exposed to tail risk. Consistent with
expectations, the price of tail risk is positive and significant in most of the countries in my
sample.
There is the vast literature on international market integration, shock transmission, and contagion
(Bekaert, Harvey, and Ng (2005), and Bakaert, Ehrmann, Fratzscher, and Mehl (2014)). I add to
the literature by examining role of tail risk during financial crisis and show that tail risk acts as
one of the sources of contagion during the period. In addition, my work also relates the growing
literature on the global financial crisis of 2007 to 2009. This includes articles focusing on the
drivers of the transmission of the crisis across firms and markets within the United States, such
as Tong and Wei (2010), Almeida et al. (2012), and Diebold and Yilmax (2010), or articles
taking a more macroeconomic perspective such as Eichengreen et al. (2012).
The findings of this paper also have important implications for international investment and
portfolio diversification. In the traditional capital asset pricing model, any systematic fluctuation
of asset prices is captured solely by market risk. Therefore, the covariance of stocks returns with
global market returns is the key to the success of international portfolio diversification. However,
the findings in this paper show that the tail risk also systematically affects asset prices, and is a
globally priced risk factor. Hence, investors should take tail risk into consideration when they
seek to diversify away risks in global financial markets. The significant pricing of global tail risk
in developed and open countries implies the importance of global investors and the relatively
high degree of financial market integration in such countries. Supporting this view, Chan, Covrig,
and Ng (2005) show that countries with these properties attract more global investors. The
finding indicates that stocks that perform well when tail risk is high are appreciated by global
investors as tail risk is an important concern, especially when investors rebalance their portfolios
globally in the face of high likelihood of market wide extremes.

The rest of the paper is organized as the following. Section 1 presents the empirical framework
and hypotheses. Section 2 briefly introduces the tail risk measure used in the paper, describes the
data and the sample construction procedure. Section 3 provides empirical evidence on the pricing
of country, and global tail risk in the international financial markets. Section 4 tests whether tail
risk acts as a possible source of contagion during financial crisis. Section 5 concludes.
I. Empirical Methodology
This section describes the main assumption in the paper and empirical approach used to test the
hypothesis. In this paper, the risk factors other than tail risk considered are well-known and well-
studied risk factors such as market factor in CAPM, small-minus-big (SMB) and high-minus-low
(HML) factors in Fama-French factors model (Fama and French 1993), and momentum (MOM)
factor.
Tail risk, constructed each month using daily returns in each country following Jiang and Kelly’s
(2014) method, captures the common time-varying component of return tails based on
assumption that an asset’s return obeys the power law probability distribution. Applied to the
pooled cross-section each month, it takes the form
∑
, (1)
, where is the kth daily return that falls below an extreme value threshold during month
t in country i, and is the total number of such exceedances within month t in country i. The
threshold is chosen by the econometrician and defines where the center of the distribution
ends and the tail begins. It represents a suitably extreme quantile such that any returns below this
cutoff are assumed to obey the specified tail distribution. Following Jiang and Kelly (2014), here
I define as the fifith percentile of the cross-section each month in each country.
After constructing tail risk for each country at each month, I construct global and local specific
tail risks following Bekeart, Hodrick and Zhang (2009) in order to better distinguish the effect of
10
tail risk between global part and local specific part. The global tail risk at each month t, ,
is calculated as the value weighted average of country tail risks:
∑
∑ , in which is country i’s size at time t.
Correspondingly, the local specific tail risk for each country i at time t, , is estimated
from the following regression using whole sample observations:
. As a result, captures the orthogonal/residual component in country tail risk
estimate with respect to global tail risk at each time t. Similarly, I construct country market
factors, and SMB/HML/MOM factors following method described on French’s website, and then
decompose the factors into 2 components, the part correlated with global factor (which is the
value weighted average of factors at each time) and the local specific part for each country.
1.1 Tail Risk in International Financial Markets
The main assumption I have is that investors’ marginal utility is increasing in tail risk. As a result,
the stochastic discount factor is also increasing in tail risk. This assumption has three testable
implications. The first implication is related to time series equity premium time series. As
investors are tail risk averse, an increase in tail risk will increase the return required by investors
to hold any tail risky assets. To test this, I estimate a simple regression of market return on tail
risk, as stock market as a whole is subject to its tail risk, like any other assets:
, (2)
, (3)
in which is tail risk estimated from (1) for country i at time t, and is market return
for country i at time t. In contemporaneous regression (2) I use monthly market returns as
dependent variable, and in predictive regressions (3) I use next one month or one year market
return. All the observations used in the regression are at monthly frequency. To address the
overlapping estimation window problem in the predictive regression, I adjusted statistical
11
inferences using Newey-West standard error correction with lag equal to 1 or 12, respectively.
To be consistent with my assumption, coefficient estimate on tail risk, , in (2) and (3) should
be positive and significant.
As different countries have different level of integration into the global market, investors can be
sensitive to global tail risks in some countries, while investors in other countries can be more
sensitive to local specific tail risks rather than the global tail risks. For example, in a small and
open market like Singapore, which is highly integrated into global market, investors might invest
mainly in global portfolios, thus are more sensitive to global tail risk. On the other hand, in
closed market which lowly integrates with global market, investors might hold portfolios mainly
contain local assets, thus are more sensitive to local specific tail risk. Overall, investors would
demand different returns to hold portfolios with different exposure to global or local specific tail
risk. In order to test this hypothesis, I construct global tail risk, , and local specific tail risk,
, based on g country tail risk, ,and estimate the following regression:
, (4)
, (5)
and,
, (6)
, (7)
in which is global tail risk at time t, and is local specific tail risk for country i at
time t. Global tail risk is constructed as the value weighted average of countries’ tail risks
at time t. And local specific tail risk is the orthogonal component in country tail risk
estimate with respect to global tail risk. Similarly, as investors are averse to tail risk, I expect
coefficient estimate on tail risks, and , in (4), (5), (6), and (7) should be positive and
significant.
12
The second implication is related to cross-sectional stock returns. As investors are averse to tail
risk, they will price assets with better hedge to tail risk higher and require lower expected returns.
To test this, I sort stocks based on their sensitivity to tail risk and compare returns between high
and low sensitivity groups. In line with the aggregate analysis above, I estimate country tail risk
sensitivities and global tail risk sensitivities of individual stocks with regression of the form:
, (8)
, (9)
where is the monthly return for stock j in country i at time t, is tail risk estimated
from (1) for country i at time t, is global tail risk at time t, and is local specific
tail risk for country i at time t. The regression is conducted each month using past 60 months
observations.
In line with the intuition behind aggregate tail risk regressions, I expect that stocks with high
values of are those that most sensitive to tail risk in country j, and are deeply discounted
when tail risk is high and have high expected returns going forward. On the other hand, stocks
with low or negative are good tail risk hedges because, when tail risk rises, their prices rise
contemporaneously, and their expected future returns fall. Overall, I expect that stocks in the
high sensitivity group should on average earn higher returns than stocks in low sensitivity group.
The third implication, closely related to the second, is that tail risk should be priced across time,
even after controlling for other risks. To test this, I conduct Fama-Macbeth regression and I
expect that tail risk should be positively and significantly priced:
∑ , (10)
in which and are loadings on global and local specific tail risks for stock j in country i
at time t estimated from rolling window regression (9). is control variable for stock
13
j in country i at time t. In the regression, the control variables used are size, market to book ratio,
and market/SMB/HML/MOM betas. I expect to be positive and significant in countries
that are highly integrated with world financial market, and to be positive and significant
in countries that are lowly integrated with world financial market.
In order to check whether tail risk can be priced predictively, I also estimate rolling regressions
and obtain predictive loadings on global and local tail risks, at each month t:
. (11)
And then using the predictive loadings obtained from (11), I perform cross-sectional regression
at each month in each country:
∑ . (12)
To be consistent with my expectation, the coefficient estimates should be positive and
significant in countries that are highly integrated with world financial market, and should
be positive and significant in countries that are lowly integrated with world financial market,
with persistent local specific tail risk.
For robustness checks, I also perform cross-sectional regression across countries, developed or
emerging markets, or different regions. When the regression is performed within more than one
country, country dummies are added to control for unknown country-specific effects.
I estimate the following model each month to obtain contemporaneous tail risk price estimates
across all countries, developed/emerging markets, or five different regions:
∑ ∑ (13)
14
, where and are loadings on global and local specific tail risks for stock j in country i at
time t estimated from rolling window regression (9). is the dummy variable for
country i.
To examine whether tail risk can be priced predictively, similar to (12), I use the predictive
loadings obtained from (11) to perform cross-sectional regression at each month across all
countries, developed/emerging markets, or five different regions:
∑ ∑ . (14)
Overall, I expect results from (13) and (14) are consistent with results from (10) and (12), that
is positive and significant in countries that are relatively highly integrated with world
financial market, and is positive and significant in countries that are lowly integrated with
world financial market.
1.2 Tail Risk during Financial Crisis
After investigating whether tail risk is a globally priced risk factor, I then proceed to empirically
examine the role of tail risk during a special time period – 2007 to 2009 financial crisis, during
which tail risk is high and extreme events tend to happen more frequently. First, I examine
whether tail risk, as I expected, is higher during this crisis period:
, (15)
∑ , (16)
in which is a dummy variable which equals to 1 if month t is during the crisis period.
is the dummy variable for country i. If extreme events are more likely to occur during
financial crisis, I expect that estimated from (15) and (16) should be positive and significant.
During the crisis, it is also possible that investors change their risk exposure towards tail risk
accordingly, as investors might shy away from tail risky assets and flee to safe assets. Also,
15
investors might be more averse to tail risk by requiring a higher risk premium during the crisis.
Therefore, I examine whether stocks’ risk exposures are different during the financial crisis, and
whether investors are more averse to tail risk by estimating following regressions:
∑ , (17)
∑ , (18)
∑ , (19)
∑ , (20)
in which and are loadings on global and local specific tail risks for stock j in country i
at time t estimated from rolling window regression (9). is a dummy variable which
equals to 1 if month t is during the crisis period. is the dummy variable for country I
firm j. If investors shy away from risky assets during the financial crisis, I expect that
estimated in (17)-(20) should be positive and significant.
Following the setting in Bakaert, Ehrmann, Fratzscher, and Mehl (2014), investors’ risk aversion
may be influenced by level of global risks, during crisis time. As a result, investors shun risky
assets and flee into safer assets when their risk aversions substantially increase during the crisis.
As tail risk is a globally priced risk factor, it is important to examine the role of tail risk affecting
investors’ investment decisions during the crisis time. In order to test this, I formulate an
international factor model with 4 kinds of factors: global & local market factor, global & local
SMB, global & local HML, and global & local MOM. The full model is the following:
, (21)
, (22)
, (23)
16
, (24)
, where is monthly excess return for stock j in country i at time t (i.e. the return minus the
three-month US T-bill rate in monthly unit). is the dividend yield of the stock j (so that
the expected excess return is a linear function of the lagged excess return and dividend yield).
is a vector of the factors (i.e. global and local market factors, etc). is a crisis dummy at time t.
It equals 1 if time t is in the crisis. and are global and local specific tail risk
variables that is designed to capture time and cross-sectional variation in factor exposure.
When only including global and local market factors, the model potentially embeds 2 CAPMS as
special cases: a domestic CAPM when on the global market factor is set to zero; and a world
CAPM when on the local market factor is set to zero. When including global and local market
factors, as well as global and local SMB and HML factors, the model embeds 2 Fama-French
three factors model as special cases: a domestic Fama-French three factors model when on the
global factors are set to zero; and a world Fama-French three factors model when on the local
factors are set to zero. Similarly, when including global and local market, SMB, HML and MOM
factors, the model embed 2 four factors model as special cases as well: a domestic four factors
(Fama-French three factors plus momentum) model, and a world four factors model.
Following naming convention in Bakaert, Ehrmann, Fratzsher, Mehl (2014), the “contagion
model” is the full model where everything is included. When is excluded from the model for
all time, I refer to it as the “interdependence model”. And when both and tail risks (
and ) are excluded, I refer to it as the “base model” in which factor exposure are the same
no matter in the crisis or not. Under the null hypothesis, the co-movement between various
stocks is determined by the factor exposures and the variance-covariance matrix of the factors.
As the factors are orthogonal, interdependence model can potentially fit the observed increase in
correlations during the crisis through an increase in factor volatilities. The model works because
the correlation between a stock return and a factor is the beta with respect to the factor, times the
ratio of factor to stock return volatility, which can be shown to be increasing in factor’s volatility.
17
As volatilities tend to dramatically increase during crises, increased correlations are thus not
necessarily indicative of contagion (Forbes and Rigobon (2002)).
In the contagion model, in equation (15) captures contagion unrelated to the observable factors
of the model. If is substantially negative for a set of stocks, then these stocks show excess
co-movement during the crisis. In this paper, I used global and local specific tail risk as a
potential channel and test whether risk aversion to tail risk can help to explain the contagion
during financial crisis. If tail risk is a potential channel of contagion during crisis, then we should
observe the following: first, is significantly negative in contagion model; second, adjusted R-
square from contagion model should be highest among three models; third, contagion model
should be able to predict stock returns during crisis time better than other two models.
II. Data
Daily returns are calculated using a daily total return index, which is adjusted for stock splits and
dividend payments, from Datastream for all available stocks from 45 countries for the period of
January 1980 to December 2014. US stock market daily and monthly data are obtained from
CRSP and Compustat during the sample period. According to the MSCI, there are 23 developed-
market and 23 emerging-market countries. The initial sample covers 62552 stocks from 46
countries.
To build a reliable sample, I applied the following screening procedures following to those in
Lee (2011) and Hou, Karoyli, and Kho (2011). For a stock to be included in the sample, it should
have positive market capitalization data, as well as positive shares outstanding and stock price, in
US dollars at the end of previous month. I select only stocks from major exchanges, which are
defined as those in which the majority of stocks for a given country are traded. Most countries in
the sample have a single major exchange except for China (Shenzhen and Shanghai stock
exchanges), Germany (Frankfurt stock exchange and Xetra), Japan (Osaka and Tokyo stock
exchanges), and the US (Amex, NYSE, and Nasdaq). I include only common stocks by
excluding stocks with special features. First I exclude stocks with Datastream defined type as
18
American Depositary Receipt, Closed-End Fund, Exchange-Traded Fund, Genussschein (Profit
Participation Certificate), Global Depositary Receipt, Non-voting Depository Receipt, Preference
Share, Warrant. In addition, I exclude stocks with special features by examining the names of the
securities. Examples of such name filters are as follows. I extracted stocks with names including
“REIT”, “REAL EST”, “GDR”, “PF”, “PERF”, or “PRF” because these terms could represent
real estate investment trusts, global depository receipts, or preferred stocks. In Belgium, stocks
with names including “AFV” and “VVPR” are dropped as they have preferential dividend or tax
incentives. In Canada, income trusts excluded by removing stocks with names including
“INC.FD”. In Mexico, shares of the types ACP and BCP are removed because they are
convertible into series A and B shares, respectively, after one year. In France, ADP and CIP type
of stocks are dropped because they carry no voting rights but carry prefenrential dividend rights.
In Germany, GSH type of shares is excluded because they offer fixed dividends and no voting
rights. In Italy, RSP shares are dropped due to their nonvoting provisions. For US stocks, I only
include stock with share code 10 or 11. To avoid survivorship bias, I retain all data for dead
stocks in the sample and exclude stock observations after the dead date provided by Datastream.
The monthly sample is constructed based on daily data after implementation of all these screens
described above. The proxy for tail risk is calculated following method in Jiang and Kelly (2014),
which calculated using lower 5% daily return data in each month for each country. To make sure
that a country has sufficient cross-sectional distribution of daily data to construct tail risk
estimates, I require that a country should have at least 100 stocks with daily returns available in a
month to be included in the sample from 1980-2014. In addition, a country has to have more than
60 month of tail risk estimates to be included in the sample. As a result, my final sample contains
64799 firms from 40 countries. I use the 30-day US Treasury bill as a risk-free asset, which is
obtained through K. French’s data library.
Table 1 reports countries’ summary statistics. The first 3 columns report countries’ name, market
development, and countries’ region. Next 4 columns report the beginning year of coverage,
number of firms, number of firm-month and firm-day observations included in the sample for
19
each country. In total there are 10428828 firm-month observations and 218459208 firm-day
observations included in the sample. Country US contains the most number of firms, as well as
firm-month/firm-day observations across all countries, while country Austria contains the least.
The total number of stocks in the sample is 64799 and varies across countries and years. During
the sample period, the country with largest number of stocks in the sample is the US (7406 firms
in 1998), and the country with smallest number of stocks is Mexico (101 firms in 1992). The
starting year of sample coverage also varies across countries. Egypt, which has the shortest
sample period, has data beginning with 1999, while the starting year is 1980 for most of the
developed countries. The last four columns of Table 1 show the time series average of cross-
sectional monthly median return, size, and book to market ratio in each country, as well as the
time series average of market total size of each country. The returns are all calculated using total
return index denominated in US dollar. The time series average of cross-sectional median varies
a lot across different countries, with monthly return ranging from -0.60% in India to 0.37% in
China, firm size ranging from 2.13 Million in India to 301.09 Million in Spain, and book to
market ratio ranging from 0.34 in China to 1.62 in Russia. Across all countries, US have the
largest market size over time, and Czech Republic is the smallest market in the sample.
Table 2 reports summary statistics of countries’ tail risk estimates. Tail risk is constructed each
month using daily returns in each country using equation (1), following Jiang and Kelly’s (2014)
method, and it captures the common time-varying component of return tails. The global tail risk,
GTail, is calculated as the value weighted average of country tail risks. The local specific tail risk,
LTail, is the orthogonal component in country tail risk estimate with respect to global tail risk.
Figure 1 plot the time series of global tail risk and tail risk estimated for United States. In the
graph, global and US tail risks appear to fluctuate together. During the technology boom, both
globally and US tail risks retreat sharply but briefly, then rising to the highest post-2000 level.
And bother are high during the recent financial crisis and recessions.
20
Table 2 reports the summary statistics of countries’ tail risk estimates. Across all countries, tail
risk estimates appear to be persistent over time. 33 out of 40 countries have AR(1) coefficient
bigger than 0.5, and can be as high as 0.90 in France and India. Countries’ time series mean,
standard deviation, and median of tail risks are reported in Table 2. Russia and Peru, with mean
of tail risk equal to 1.16 and 1.17, appear to have largest tail risk on average across time in all
countries. These two also have highest standard deviation, and median of tail risks across
countries. The last 6 columns in Table 2 report the correlation coefficient between country tail
risk and global/US tail risks and corresponding p value. All countries’ tail risk estimates
significantly correlate with global tails at 5%. Most developed countries’ tail risk significantly
correlate with US tails at 5% level, except Austria, Israel, and Italy. Among 18 emerging markets,
only 10 have tail risks significantly correlate with US tails.
III. Pricing of Tail Risks
Investors in the market are risk averse and their marginal utility is increasing in risks. I assume
that investors are also averse to tail risk as tail risk is a type of risk in the market. A high tail risk
increases the return required by investors to hold any tail risky portfolios, such as market
portfolio. In addition, as tail risk is quite persistent in most of the countries, investors might only
dynamically adjust their discount rates in response to shocks that are informative about future
level of tail risks. Empirical I test whether tail risk positively correlates with contemporaneous
market return and positively predicts future market return. In addition, assets that better hedge
tail risk will command a relatively high price and earn low expected returns as investors require
higher returns to hold tail riskier portfolios. I tested this implication by comparing average
returns of assets to their estimated tail risk sensitivities cross-sectionally. Last, tail risk should be
positively priced in the market and I test this using Fama-Macbeth approach.
3.1 Tail risk and stock market returns
If investors are tail risk averse, a high tail risk increases the return required by investors to hold
any tail risky portfolios, even market portfolio. As a result, I expect tail risk to be positively
21
correlates with contemporaneous market return. In addition, as tail risk is quite persistent in some
countries, investors might only dynamically adjust their discount rates in response to shocks that
are informative about future level of tail risks, thus tail risk should be able to positively predict
future market return in countries with highly persistent tail risks. I test above hypothesis whether
tail risk positively correlates contemporaneous market return and positively predicts future
market return by estimating contemporaneous regression (2) and predictive regression (3),
, (2)
, (3)
in which is tail risk estimated from (1) for country i at time t, and is market return
for country i at time t. In contemporaneous regression (2) I use monthly market returns as
dependent variable, and in predictive regressions (3) I use next one month or one year market
return.
As different countries have different level of integration into the global market, as well as
development, market quality, and macro conditions, investors can be sensitive to global tail risks
in some countries, while investors in other countries can be more sensitive to local specific tail
risks rather than the global tail risks. As a result, investors would demand different returns to
hold portfolios with different exposure to global or local specific tail risk. In order to test this
hypothesis, I decompose country tail risk, , into global tail risk, , and local specific
tail risk, , and estimate contemporaneous regressions (4) and (6), and predictive
regressions (5) and (7):
, (4)
, (5)
and,
22
, (6)
, (7)
in which is global tail risk at time t, and is local specific tail risk for country i at
time t. Global tail risk is constructed as the value weighted average of countries’ tail risks
at time t. And local specific tail risk is the orthogonal component in country tail risk
estimate with respect to global tail risk. I adjust statistical inferences using Newey-West standard
error correction for the overlapping data in predictive regression (3), (5), and (7).
Table 3 reports the contemporaneous regression results for (2), (4), and (6). Panel A reports the
summary of estimated coefficients across 40 countries in the sample. Panel B results the value
weighted or equally weighted coefficient estimates, , for countries in different regions. In all
countries, country tail risk, , is positively correlated with market return, among which 37
countries have positive and 5% significant coefficients, except Hong Kong, Malaysia, and India.
Global tail risk, , correlated with market returns positively in all countries, and significant
in 39, except China. It is conceivable that investors in China are not so averse to global tail risk
as the stock market in China is highly regulated and protected by the government from the rare
disasters. When controlling for local specific tail risk, global tail risk still correlated with
market returns positively in all countries, and significant in 39. On the other hand, Local tail risk,
, positively correlates with market return in 34 countries, and significant in 24 countries
(9 out of 18 emerging countries, and 15 out of 32 developed countries). In markets like Austria,
Hong Kong, Singapore where market is open and country tail risk is highly correlated with
global tail risk, investors might only averse to global tail risk that significantly correlates with
stock market returns.
Table 4 reports the predictive regression results for (3), (5), and (7). Similarly to Table 3, panel
A reports the summary of estimated coefficients and panel B reports the value or equally
weighted coefficient estimates, , across different country. Overall in 30 countries, country tail
23
risk, , can positively predicts future next one month market return, among which 7
countries (Austria, Portugal, Unite States, Cezech Republic, Peru, Philippines, and Thailand)
have positive and 5% significant coefficients. These 7 countries all have highly persistent
country tail risks, which is the key assumption that we have in order to observe the predictive
power of country’s tail risk. As if tail risk is persistent in a country, investors might only
dynamically adjust their discount rates in response to shocks that are informative about future
level of tail risks.
In addition, global tail risk, , predicts next one month market returns positively in 37
countries, and 5% significant in 8 (Austria, New Zealand, Portugal, Czech Republic, Egypt,
Greece, India, and Philippines). When controlling for local specific tail risk, global tail risk
still predict next one month market return positively in 37 countries, and 5% significant
in 8. On the other hand, Local tail risk, , positively predicts next one month market return
in 28 countries, and 5% significant in 2 countries (United States, and Thailand). United States
has the largest financial market in the world and its investors not only averse to global tail risk,
but also require a compensation to hold local specific tail risky market portfolios. In Thailand,
future one month return can be predicted by local tail risk instead of global tail risk, probably
because its country tail risk lowly correlate with global tails at 0.34.
When predicting next one year market return, loadings on country tail risk is positive in 29
countries, among which 8 are 5% significant (Austria, Hong Kong, Israel, United States, Czech
Republic, Peru, Philippines, and Russia). Global tail risk, , predicts next one year market
returns positively in 38 countries, 10% significant in 17 countries, and 5% significant in 12
(Austria, Canada, New Zealand, Portugal, Spain, Brazil, Czech Republic, Egypt, Greece, Poland,
Russia, and South Africa), When controlling for local specific tail risk, global tail risk
still predict next year month market return positively in 38 countries, and 5% significant in 12.
On the other hand, Local tail risk, , positively predicts next one year market return in 25
countries, and 5% significant in 5 countries.
24
In summary, regression results of (2) – (7) presented in Table 3 and Table 4 are consistent with
my expectations that tail risk is positively correlated with contemporaneous market return as
investors are tail risk averse and require a higher return to hold a portfolio with higher tail risk.
In addition, consistent with expectation, tail risk can predict future market returns in some
countries, most of which have quite persistent tail risk time series, indicating that in these
countries investors might only dynamically adjust their discount rates in response to shocks that
are informative about future level of tail risks.
3.2 Tail risk and cross-section of expected stock returns
I next test whether tail risk helps explain differences in expected returns across stocks, consistent
with the priced tail risk hypothesis. If investors are averse to tail risk, stocks with high loadings
on tail risk will be discounted more steeply and thus have higher expected returns going forward.
On the other hand, stocks with low or negative tail risk loadings serve as effective hedges and
therefore will have comparatively higher prices and lower expected returns.
I estimate country tail risk sensitivities and global tail risk sensitivities of individual stocks with
regression (8) and (9) each month, using the most recent 60 months of data:
, (8)
, (9)
where is the monthly return for stock j in country i at time t, is tail risk estimated
from (1) for country i at time t, is global tail risk at time t, and is local specific
tail risk for country i at time t.
Stocks are then sorted into 10 portfolios in each country based on their estimated country tail risk
loadings or global tail risk loadings. For each month I long portfolios with highest tail risk
loadings and short portfolios with lowest tail risk loadings and track average monthly value-
weighted portfolio returns of this long-short strategy in a twelve-month or one-month post-
25
formation window. Portfolio returns are out-of sample, as there is no overlap between data used
for estimating loadings and data used in the post-formation performance period. To address
the overlapping estimation window problem, I adjust standard error with lag equal to 12 (if post-
formation window is one year) or 1 (if post-formation window is one month) using Newey-West
method.
Table 5 reports the annualized long-short portfolio returns. Panel A reports the summary of
portfolio spreads across countries. Panel B reports detailed value or equally weighted spreads of
portfolios returns across all countries, or in different markets, or in different regions. On average
across all countries, if post-formation window is one year, stocks in the highest global tail risk
loading portfolios earn value-weighted average annual returns 6.35% higher than stocks in the
lowest portfolio, with a t-statistics of 6.64. When post-formation window is one month, stocks in
the highest global tail risk loading portfolios earn value-weighted average annual returns 5.06%
higher than stocks in the lowest portfolio, with a t-statistics of 3.84. Comparing developed
markets and emerging markets, return difference between stocks in the highest and lowest global
tail risk loading portfolios is significant, but always higher in emerging markets. As emerging
markets are in general less developed, vulnerable to global disaster event, and has weaker
enforcement of investor protections, investors might require a higher return to hold stocks with
higher exposure to global tail risk. Among the emerging countries, return difference in emerging
Europe/Middle East/Africa are particular high as investor in these market probably exposed more
to global markets than investors in emerging Asia. The return difference between stocks in the
highest and lowest global tail risk loading portfolios is positive, but not significant in US,
consistent with results from the aggregate analysis.
When sorting stocks based on loadings on country tail risk, on average across all countries,
stocks in highest loading portfolios on average earn 3.60% higher value-weighted annual returns
if post-formation window is one year, or 3.11% is post-formation window is one month, than
stocks in lowest loading portfolios. Comparing developed and emerging markets, the return
difference in both markets are positive but only significant in developed markets. As the country
26
tail risk is the combination of global tail risk and local specific tail risk, results could be
insignificant as stocks with the lowest loadings of country tail risk could be those have high
loadings on global tail risk yet very low loadings on local specific tail risk.
In addition, return difference between stocks in highest and lowest country tail risk loading
portfolios is positive and 5% significant in regions such as developed Europe. It is also
significant in United States, 7.04% if post-formation is one year, or 4.85% if post-formation is
one month.
In summary, results are broadly consistent with expectations and priced tail risk hypothesis, that
tail risk helps explain differences in expected returns across stocks.
3.3 Tail risk and its risk price
Previous results, that tail risk correlates with market aggregate return, tail risk can predict future
market return if persistent and tail risk helps explain cross-sectional differences in expected
returns, are consistent with priced tail risk hypothesis. In the tests, country’s tail risk measure is
not as clean as using global and local specific tail risks, as country’s tail risk captures the mixture
of both global and local specific tail risks. Therefore, in this section, I investigate the pricing of
global and local specific tail risks using cross-sectional regressions.
I employ individual stocks as test assets because an analysis at the level of individual stocks
provides the following benefits. First, the use of individual stocks as test assets helps to avoid
potentially spurious results that could arise when characteristic-based portfolios are used as test
assets (Brennan, Chordia, and Subrahmanyam (1998), Berk (2000)). Second, potential loss of
information contained in each stock can be minimized by performing empirical tests at the level
of individual stock. Third, a stock-level analysis could increase the power of the test by
providing ample observations for empirical tests. It is also suitable for controlling for individual
stock characteristics, such as market capitalization and book-to market ratio. On the cost side, the
loading estimated at the level of individual stock generally have a higher level of noise than
27
those estimated at the portfolio level and possibly decrease the significance of the coefficients
estimates.
The individual stock global and local specific tail risk betas, and , are estimated from
previously mentioned equation (9). To avoid look-ahead bias, I use rolling window of 60 months
to obtain a time series of betas for each stocks. This 5-year rolling window starts at either
January 1980 or the first month in which stocks are present in the sample. The window rolls
forward at monthly interval. A stock should have at least 36 monthly returns within the 5 year
window in order to estimate its betas. Similarly, I obtained stock’s market, SMB, HML, and
MOM betas.
The sample period is relatively short. In addition, unlike the case of US, the quality of data from
other countries is not guaranteed (Ince, and Porter (2006), Bekaert, Harvey, and Lundblad
(2007)). Given these potential problems, I preform the cross-sectional regressions not only
within each country, but also across countries, developed or emerging markets, or different
regions. When the regression is performed within more than one country, I run regression at each
month with country dummy variables to provide an interpretation of the coefficient estimates in
terms of within-country effects and to control for unknown country-specific effects (McLean,
Pontiff, and Watanabe (2009)).
3.3.1 Pricing for tail risks by country
I present the results of the cross-sectional regression by each country in this sub-section. Table 6
reports the summary of time series average of risk price estimated for global and local specific
risk from equation (10),
∑ , (10)
in which and are loadings on global and local specific tail risks for stock j in country i
at time t estimated from rolling window regression (9). is control variable for stock
28
j in country i at time t. In the regression, the control variables used are size, market to book ratio,
and market/SMB/HML/MOM betas.
The first two rows in table 6 reports the averages of tail risks price across all countries. No
matter what control variable is included in the regression, global tail risk is consistently
positively and significantly priced on average across all countries, while local specific tail risk is
not even marginally significant. When average across developed or emerging markets, global
and local specific tail risk are both positively significantly priced in developed markets, while
only global tail risk is significantly priced among emerging markets.
I then average across five different geographic regions: Developed Asia, Developed Europe,
Emerging Asia, Emerging Europe/Middle East/Africa, and Latin America. Countries included in
each group are specified in Table 1. Among Developed countries, only across developed Europe
both global and local specific tail risks are significantly priced. In developed Asia only local
specific tail risk is significantly price. In addition, among emerging markets, global tail risk is
only significant priced in emerging Asia, but not in emerging Europe/Middle East/Africa, which
is conceivable as countries included in this group are very different from each other in terms of
economic, political, and geographic conditions.
I also check whether tail risk can be priced predictively. Table 7 reports the summary of time
series average of predictive risk price estimated for global and local specific risk from equation
(12),
∑ . (12)
in which and are predictive loadings on global and local specific tail risks for stock j in
country i at time t estimated from rolling window regression (11). is control
variable for stock j in country i at time t. Similar to (1), the control variables used are size,
market to book ratio, and market/SMB/HML/MOM betas.
29
The first two rows in table 7 reports the averages of tail risks price across all countries. No
matter what control variable is included in the regression, global tail risk is positively priced, but
only with marginal significance on average across all countries, while local specific tail risk is
not significant and sometime has negative sign. When average across developed or emerging
markets, global and local specific tail risk has similar predictive risk price as across all countries.
The averages across five different geographic regions are also reported. Among Developed
countries, global tail risk has marginally significant risk price in developed Asia. And among
emerging markets, global tail risk only has marginally significant risk price as well.
In summary, the results are consistent with hypothesis that tail risk has positive risk price. And in
some countries, the predictive risk price for tail risk is also positive and significant.
3.3.2 Pricing for tail risks across countries, markets, and regions
For robustness checks, I also perform cross-sectional regression (13) across countries, developed
or emerging markets, or different regions, and I present the results in this sub-section. Table 8
reports the summary of time series average of risk price estimated for global and local specific
risk, from equation (13),
∑ ∑ (13)
, where and are loadings on global and local specific tail risks for stock j in country i at
time t estimated from rolling window regression (9). is the dummy variable for
country i.
No matter what control variable is included in the regression, across all countries,
developed/emerging markets, as well as three different regions, global tail risk is always
positively and significantly priced at 5%, except Developed Asia and Emerging Europe/Middle
East/Africa where countries differ significantly from each other. In most cases, global tail risk
price is always more significant than local specific risk price, except in Developed Europe. In
30
addition, local specific tail risk appears to be significantly priced in Developed Europe and Latin
America, indicating that investors in those countries require compensation to hold local tail risky
portfolios.
Table 9 reports the summary of time series average of predictive risk price estimated for global
and local specific risk from equation (14),
∑ ∑ . (14)
The results are mixed. In most cases, both tail risks don’t have significant predictive risk price,
regardless the cross-sectional regression is performed across all countries, or in different regions.
However, when pooling all countries together, local tail risk price appear to be slightly more
significant than global tail risk price, but is just marginally significant. When comparing between
developed or emerging markets, results are a bit stronger in developed markets than emerging
markets.
In summary, the results are consistent with hypothesis that tail risk is a globally priced risk factor.
It has positive risk price and investors require higher return to hold tail riskier assets/portfolios.
IV. Tail risk as contagion channel during financial crisis
In previous section, I show that tail risk is a globally priced risk factor. In this section, I will
proceed to empirically examine the role of tail risk during a special time period – 2007 to 2009
financial crisis, during which tail risk is high and extreme events tend to happen more frequently.
First, I examine whether tail risk, as I expected, is higher during this crisis period:
, (15)
∑ , (16)
31
in which is a dummy variable which equals to 1 if month t is during the crisis period.
is the dummy variable for country i. If extreme events are more likely to occur during
financial crisis, I expect that estimated from (15) and (16) should be positive and significant.
During the crisis, investors might shy away from tail risky assets and flee to safe assets, and
investors might be more averse to tail risk by requiring a higher risk premium during the crisis.
Therefore, I examine whether stocks’ risk exposures are different during the financial crisis, and
whether investors are more averse to tail risk by estimating following regressions:
∑ , (17)
∑ , (18)
∑ , (19)
∑ , (20)
in which and are loadings on global and local specific tail risks for stock j in country i
at time t estimated from rolling window regression (9). is a dummy variable which
equals to 1 if month t is during the crisis period. is the dummy variable for country I
firm j. If investors shy away from risky assets during the financial crisis, I expect that
estimated in (17)-(20) should be positive and significant.
Table 10 reports results of (15)-(20). Overall, consistent with expectations, estimated from (15)
– (20) are positive and significant. Not only tail risk is relatively higher during the crisis period,
but also the risk price of tail risk is higher during the time.
Following Bakaert, Ehrmann, Fratzscher, and Mehl (2014), during crisis time, investors shun
risky assets and flee into safer assets when their risk aversions substantially increase. Therefore,
investors’ risk aversion may be influenced by level of global risks, as during crisis time tail risk
is high and extreme events tend to happen more frequently, As a result, as tail risk is a globally
32
priced risk factor, it is important to examine the role of tail risk affecting investors’ investment
decisions. In this section, I investigate whether tail risk serves as a possible contagion channel
during the financial crisis.
First I construct 2 types of factors – global factors, and local specific factors. The global factor is
the value-weighted country factors across all countries in the sample, and the local specific factor
is the orthogonal component in a country’s factor with respect to global factor. Similar to
Bakaert, Ehrmann, Fratzscher, Mehl (2014), I formulate the international factor model with 4
kinds of factors: global & local market factor, global & local SMB, global & local HML, and
global & local MOM:
The full model is described in section 1 equation (15) - (18).
When only including global and local market factors, the model potentially embeds 2 CAPMS as
special cases: a domestic CAPM when on the global market factor is set to zero; and a world
CAPM when on the local market factor is set to zero. When including global and local market
factors, as well as global and local SMB and HML factors, the model embeds 2 Fama-French
three factors model as special cases: a domestic Fama-French three factors model when on the
global factors are set to zero; and a world Fama-French three factors model when on the local
factors are set to zero. Similarly, when including global and local market, SMB, HML and MOM
factors, the model embed 2 four factors model as special cases as well: a domestic four factors
(Fama-French three factors plus momentum) model, and a world four factors model.
Following Bakaert, Ehrmann, Fratzsher, Mehl (2014), when is excluded from the model for
all time, I refer to it as the “interdependence model”. And when both and tail risks (
and ) are excluded, I refer to it as the “base model” in which factor exposure are the same
no matter in the crisis or not. Under the null hypothesis, the co-movement between various
33
stocks is determined by the factor exposures and the variance-covariance matrix of the factors.
As the factors are orthogonal, interdependence model can potentially fit the observed increase in
correlations during the crisis through an increase in factor volatilities. The model works because
the correlation between a stock return and a factor is the beta with respect to the factor, times the
ratio of factor to stock return volatility, which can be shown to be increasing in factor’s volatility.
As volatilities tend to dramatically increase during crises, increased correlations are thus not
necessarily indicative of contagion (Forbes and Rigobon (2002)).
In the contagion model, in equation (15) captures contagion unrelated to the observable factors
of the model. If is substantially negative for a set of stocks, then these stocks show excess
co-movement during the crisis. In this paper, I used global and local specific tail risk as a
potential channel that helps to explain the co-movements among stocks during financial crisis.
Mounting evidence suggests that international asset prices are quite sensitive to global measures
of risk aversion, and risk aversion of investors may substantially increase during the crisis,
making them shun risky assets and flee into safer assets. It is shown from the previous results
that investors are averse to global tail risk across all countries, and in some countries, local
specific tail risk is also priced. Therefore, here I test whether risk aversion to tail risk can help to
explain the contagion during financial crisis.
Table 10 reports the model estimation results for base model, interdependence model, and
contagion model (full model). Consistent with expectation, is negative for global tail risk and
significant at 1% level, suggesting that global tail risk serves a potential channel of contagion
during crisis. In addition, factor exposures to global and local financial factors varies with tail
risks, also suggesting tail risks could be a potential channel of contagion during crisis. The
substantial positive correlation between the interdependence and contagion coefficient indicates
that portfolios that were exposed to the factors before the crisis experienced the strongest
contagion during the crisis. This is true both for international and domestic exposure. Note that
global tail risk contributes more to the change in exposure to global financial factor, while local
specific tail risk contribute more to the change in exposure to local financial factor. This is
34
expected as investors who invest in global market care more about global tail risk, while
investors focus on local market are more averse to local specific tail risk. Adjusted r square is
higher in contagion model (12.62%) by 1 basis point, suggesting that contagion model can fit the
co-movement of stock returns the better.
What would the model predict for the crisis? If the model correctly specified, the factor
exposures are sufficient to predict the relative vulnerability across the different stocks across
different countries during the financial crisis. Table 11 reports the how well the base model,
interdependence model, and contagion model can predict stock return performance during
financial crisis across countries. The first column in Table 11 reports the real value-weighted
average excess return during financial crisis for each country. The second to fourth columns
report the deviation between the real excess returns and base model prediction, interdependence
model prediction, and contagion model prediction during financial crisis across different
countries. The computation is straightforward as we obtain estimated return stock each stock i in
country j at time t, and then obtain from these the total predicted return and compare this to the
total actual return during the crisis period.
On average across all countries, stocks monthly returns are negative, -2.88%, during financial
crisis. The countries that affected the most are in Europe and US, as well as most emerging
countries such as South Africa, Taiwan, and Thailand, where countries were affected not only in
terms of equity market performance, but also in terms of economic growth and activity. The
contagion model would predict some of the European countries to be moderately affected or not
affected, while the interdependence model predicts some of the emerging countries to be
moderately affected. The average deviation of base model from actual returns is -0.44%, and the
average deviation of interdependence model from actual returns is -0.44%. Contagion model can
predict stock performance during the crisis period better than the base model and contagion
model, with the average deviation equal to 0.12%. Note that both base model and
interdependence model over-predict the severity of the crisis on average across all countries, but
contagion model under-predicts the severity of the crisis.
35
In summary, the contagion model using global and local tail risks as a possible channel of
contagion during crisis can fit stock returns internationally the best, and also predict stock return
performance better than base model and interdependence model during the financial crisis.
Therefore, the evidence is consistent with the expectation that investors tail risk aversion
increases during the crisis, making them shun risky assets and flee into safer assets such as US
government bond.
V. Conclusion
This paper empirically investigate an equilibrium asset pricing relation with tail risks, using a
large sample of assets covering 64799 stocks from 40 countries around the world during the
period of Jan 1980 to Dec 2014.
The empirical evidence presented in the paper is supportive that tail risks are priced in
international financial markets, even after controlling for size, book-to-market, and other risks
such as market, SMB, HML, and MOM. Specifically, when tail risk is high, the
contemporaneous market return is high as investors require higher return to hold tail risky
portfolios. In the countries where tail risks are persistent, tail risk can predict future market
return as investors only adjust their discounting factors in response to the shocks in tail risks. In
addition, tail risk help to explain cross-sectional return difference as investors require higher
return to hold stocks that are not a good hedge to tail risk when tail risk is high. Results from
cross-sectional regression show that tail risk is positively and significantly priced, especially
global tail risk in more developed markets.
These findings imply that tail risk is an important concern when investors rebalance their
portfolios in the face of down markets or markets with high risk of extreme events. Therefore,
the findings have implications for international portfolio diversification, because tail risk is
another dimension to consider in addition to traditional risks.
36
In this paper, I also try to understand whether tail risk acts as a possible global transmission
channel of the crisis in equity markets. From the perspective of a factor model with global and
domestic factors, I find evidence of tail risk as a source of contagion. In addition to providing
evidence that tail risk is a potential channel of contagion during financial crisis, I also found
evidence that global tail risk is more important when global investors are present – specifically,
their exposure to global financial factor is more correlated with global tail risk than local specific
tail risk. This finding sheds some lights on the importance of possible mechanism where tail risk
is served as source of contagion during financial crisis.

Table 5.Long-short Portfolio Performance.
This table reports performance of long-short value weighted portfolios over time. The portfolios are
created by sorting stocks' sensitivity to tail risks in the market, in which the sensitivity is estimated using
past 60 month rolling window from equation (9). Panel A reports the summary of portfolio spreads across
countries. Panel B reports the spread of portfolios formed based on firms' sensitivity to tail estimates in
the country. The reported return spread is annualized. The sample period is from 1980 Jan 1st to 2014
Dec 31st.

Table 6.FM Regression Results.
This table reports summary of FM regression results with global and local specific tails used in the
regression (10). On each month in each country, I conduct cross-secitonal regression of stock return on its
sensitivity to tail risks in the market, with control variables such as size, market to book ratio,
MKT/SMB/HML/MOM betas included in the regression. The stock’s tail risk sensitivity is estimated
using past 60 month rolling window. The sample period is from 1980 Jan 1st to 2014 Dec 31st.

Table 11.Contagion Estimation Results
This table reports pooled regression results (equation (21)-(24) using all countries observations) results
Following BEFM2014 model. The dependent variable is stock return. The control variables are past
month excess return, past dividend yield, past size, and past market to book ratio. The factors used are
global and local specific factors constructed following Bekeart, Hodrick and Zhang (2009). The tail risks
used are past one month global and local specific tails. Panel A reports results using model based on
CAPM. Panel B reports results using model based on Fama-French 3 factors. Panel C reports results
suing model with risk factors of Fama-French 3 factors and the momentum factor. The sample period is
from 1980 Jan 1st to 2014 Dec 31st.
