Migration and economic development: The
unintended consequences for technological
innovation and, thus, the development of societies
arising from barriers to high-skilled immigrants
Sofia Nunes
ABSTRACT
Over the years, high-skilled immigration has been fundamental for the development of
societies, either from an economic or social perspective, but its value has been potentially
underestimated and neglected as a factor of utmost importance. In fact, numerous and
fascinating discoveries have been made by immigrants as it is the case of Scottish scientist
Alexander Graham Bell that created the telephone in 1876 while he was living in the United
States of America. However, a relatively recent wave of populism in different countries
around the world has appealed for anti-immigration policies, which generates controversy

as it raises several questions regarding its advantages and disadvantages. So, this
dissertation aims to understand the link between high-skilled immigration and technological
development, namely in advanced economies, and its impact in the development of
societies. For that matter, it was used an instrumental variable in the regression adopted,
in order to rectify eventual endogeneity problems in the high-skilled immigrants variable as
it might have a both way causation with technological innovations. Thus, the analysis done
has demonstrated that there is, in fact, a statistically significant relationship between high-
skilled immigrants and technological innovation. Placing more obstacles to the entrance of
talented non-natives will have negative consequences, namely with having less patent
applications by around 9%. On the other hand, it was also taken into account the impact that
this increase in the talent pool would have in the development of societies by doing a
multivariate regression with a quadratic transformation. Indeed, the results were that it was
necessary an employment rate of highskilled immigrants higher than around 81,67% to see
a decrease in income or wealth inequality. Thus, policymakers need to see the whole picture
when considering engaging in more restrictive immigration policies as there are
repercussions to it that can be sometimes overlooked.
1. Introduction
For decades, migration has been a topic of constant debate, namely regarding what should
be the best approach as it is a phenomenon that characterizes most societies. Both migrants
from developed and developing nations go to advanced countries, particularly those from
the Organisation for Economic Co-operation and Development (OECD), hoping to achieve

a better life and have more opportunities1, but those from poorer territories have an even
bigger motivation as they have a bigger economic gap (OECD, 2001, p. 71). So, the pursuit
for a higher quality of life in advanced countries, for the most part, has increased economic
migration of both high and low skilled immigrants, which, in turn helps to turn around the
ageing trend that is currently happening in most developed countries (Niebuhr, 2006, p. 1).
Indeed, the impact that it has in the communities is often viewed just from an economic
perspective regarding wages and employment, but the fact is that high-skilled immigration,
especially, can potentially provoke profound changes in its development through
entrepreneurship and technology innovations. However, this effect is often underestimated,
as it can help not only the host country, but also the country of origin to be more prosperous.
After the World War II, the computer revolution marked the beginning of an era that
revolutionized the world and prompted globalisation, which increased the need for
specialised workers particularly in the OECD countries coming from both developed and
developing countries (Chiswick, 2005, p. 2). The internet period facilitated the connection
between countries either by having faster transportation or the propagation of information in
seconds, for example. So, this ease in movement from nation to nation and, with it, the
disclosure of the best opportunities worldwide made people prone to move around and
pursue their dream. But, economic globalisation and the emergence of international
institutions that regulate global trade, economic relations and international monetary
cooperation, such as the International Monetary Fund, the World Bank or the International
Trade Organisation, have fuelled the argument about the global “brain drain”2. Therefore,
this revolution made societies realise the need to constantly adapt and the importance of
1 Sen, A. (2009) considers that the search for a better quality of life at a worldwide level can also be viewed as a matter of justice, in the sense that justice is beyond fairness and that it should be interpreted at a global level and not only from the point of view of a particular society, namely a developed one (p. 56). 2 “Brain Drain” is understood as “the assertion that migration tends to strip the sending nation of all its best workers” (Boeri, 2012, p. 11).

talent and specialised skills, namely the demand for specialised individuals with different
capabilities, reason why multiple countries are starting to understand the advantages of
having a friendlier policy towards high-skilled immigrants, as in those “with a degree or
equivalent qualification” (Gagliardi, 2015, p. 777), so that they would have a competitive
advantage worldwide. Indeed, from a traditional neoclassic perspective, seizing the chances
available in the market seem evident for an entrepreneur, foreign or not, especially with the
need for constant adaptation deriving from nonstop innovation, which, in turn, would
eventually equilibrate the market and, thus, benefit society (Kloosterman & Rath, 2001, p.
189). But, when an entrepreneur is an alien3, governments do not always see it from this
perspective and it is the national identity that usually comes to mind, or the change that
would happen to it. In fact, more restrictions are taking place as issues with the economic
perspectives of nationals and their national identity are getting more relevance, making
citizens unsure of the decision that should be made. And while most of the research made
on this topic is about the macroeconomic effects of migration, recent analysis has proven
that there are relevant positive spillover effects into society by the inflow of talented migrants,
namely from a demographic perspective, in which young migrants balance the demographic
transition of developed societies with an obvious impact, for instance, in financial
contributions to social security. The objective of this dissertation is to understand to what
extent high-skilled immigration has an impact on technology innovations and, thus, the
development of societies. So, it is organised as follows. Firstly, in section 2, it is going to be
done an overall revision of the literature regarding the relationship between specialised
immigration and innovation and its contribution to economic growth. Then, section 3
discusses the methodology used to estimate the effect in question and its limitations, while
taking into consideration two parts of the analysis: a first one to understand the actual impact
3 Immigrants are often referred to as ‘aliens’, not necessarily with a bad connotation (Carens, 1987).

of high-skilled immigrants in technological innovation and a second part to comprehend its
impact in the improvement of a society. Finally, some recommendations are going to be
made in terms of the best approach for immigration policy, having the appendix more details
about the analysis done.
2. Literature Review
This section has the objective of going over key aspects of this topic, which were discussed
over the years by multiple authors, starting with explaining how high-skilled immigrant and
technological innovation are interconnected, followed by a description of its role in the
development of societies.
2.1 The alliance between immigration and technology:
In the last few decades, the United States of America (USA) has become one of the most
powerful nations around the world, owing it specially to its superiority in the scientific and
technological sector through the attraction of technological entrepreneurs, as Wadhwa, V.
(2012, p. 162) suggests. In fact, a great number of innovations that completely revolutionized
the world as we know it were the work of exceptional immigrants, from Alexander Graham
Bell, with the telephone, to Elon Musk, with PayPal and SpaceX (Wadhwa, 2017), having
these boosted the acquisition of “patents at double the rate of highly educated US natives”
(New American Economy, 2011, p. 7). According to the New American Economy (2011, p.

7), an immigrant4 or its descendent create substantial new jobs, being responsible for more
than 40% of those in the Fortune 500 in 2010, which is why Tim Cook, Chief Executive
Officer of Apple Inc., admitted that “Apple would not exist without immigration, let alone thrive
and innovate the way we do” (Business Insider UK, 2017), having Microsoft Corporation
taken the same position (see Appendix A for more details about one of the leading
companies in technology, which had an important voice in the migration debate in recent
years). Therefore, companies have a unique position here as they can be the decisive factor
for a visa to be granted, namely in the case of the USA, in which these firms decide which
immigrants are more suitable to work there in order to sponsor them (Kerr, 2013, p. 17).
However, tech companies have started to protest against all the barriers in place as their
foreign employees contemplate moving to their countries of origin, which allows for these
countries to catch-up in the technological field (Warton, 2017). Wadhwa, V. (2012, p. 182)
argues that countries such as China and India are becoming prime competitors in the
scientific and technological market, whilst offering more attractive conditions to live and start
businesses. In the USA, almost two-thirds “of H-1B petitions approved in FY 2014 were for
workers in computer-related occupations” (U.S. Citizenship and Immigration Services report
to Congress, cited in Warton, 2017), so it is thought that if these restrictions take place, the
progress of tech industries would damper as these would seek the best conditions possible
and not necessarily give the jobs to American citizens (Warton, 2017). In fact, recent
immigration policies in the USA cause so much trouble in getting a visa that this nation is
not seen any more as having the best career opportunities for entrepreneurs comparing to
their home countries, where benefits and higher quality of life captivates them (Wadhwa,
4 Throughout the text, it is going to be assumed that “immigrants” refer to economic/employment-based immigration (to search for better work conditions or higher quality of life), although, in the international migration debate, it may also refer to family migration (to reunite families in destination country) and humanitarian migration (to those that were at risk in their home countries due to war, striking social conditions or political reasons) (Shachar, 2006, p. 150).

2012, p. 441). This competition for global talent comes from the economic advantages that
it can provide to a nation as human’s aptitudes are distinctive and cannot be replaced easily,
making the countries consider different programs to attract the best ones and, thus, be at
the top of the race (Shachar, 2006, p. 152). So, immigration policy is no longer seen as just
revolving around domestic preferences, but rather combining it with the strategies of other
nations, although not necessarily from a collaborative perspective, but to have the upper
hand, as Shachar, A. (2006, p. 155) argues. However, Chellaraj, et al. (2005, p. 1) assumes
that the terrorists’ attacks of September 11, 2001, in the USA had a profound alteration in
the way immigration is dealt with, which also affects the rest of the world, being in permanent
discussion how open the borders should be. Indeed, a worry with “sovereignty and
protection of domestic labour markets, including wages of nationals, the sustainability of
social security systems and social cohesion” (OECD, 2001, p. 83) has started to change this
phenomenon, namely in the USA, as more restrictive immigration policies are taking place5,
not allowing the permanent capture of highskilled immigrants as much as before, especially
for those from STEM (Science, Technology, Engineering and Mathematics) backgrounds,
reason why this situation has been entitled as the “reverse brain drain” (Wadhwa, 2012, p.
162). However, the question regarding the differences between immigrants and natives
and, thus, their uniqueness in this sector may arise. Hart, D. & Acs, Z. (2011, p. 118) claim
that their background and experiences in different cultures give migrants the perception of
society in a different light and, with that, the awareness needed to detect the best
opportunities. So, it should not come as a surprise that “16% of high-impact, high-tech
companies” (Hart & Acs, 2011, p. 120) had, minimum, one immigrant as its founder. Even
regarding innovation at the university level, colleges have a huge role in attracting talents,
while linking individuals and organisations with open-minded environments (Florida, 2006).
5 In the USA, there has been a proposal to lessen the amount of H-1B visas given in the beginning of 2017,
which are destined for foreigners employed in a specialised occupation (Business Insider UK, 2018).

The positive externalities that come from it should also be taken into consideration as it
becomes a more propitious climate for new ideas “coming from the re-combination of new
and pre-existent local knowledge” (Audretsch & Feldman 2004, cited in Gagliardi, 2015, p.
778). The brain drain from developing countries is usually a main argument that comes up
on the international migration debate, but there are two components that can undermine it.
Firstly, from an economic perspective, the remittances sent back to the home countries help
the migrant’s family to have a higher quality of life and even to invest in new properties and
businesses (Chiswick, 2005, p. 6). Indeed, the World Bank has concluded that “remittances
can be sizeable relative to per capita income in their home countries” (The World Bank,
2011, p. 16), which allows the local community to benefit from it. In addition, those that return
to their home nations after getting experience abroad will help towards the “brain gain” and
it opens the possibility of creating a relationship between richer and poorer countries, which
helps growing the economies (Chiswick, 2005, p. 6).
2.2 Boosting economies through immigration:
Nowadays, the idea of free movement of workers for those of specific countries is gaining
force. The case of European Union (EU) nationals travelling freely in the European
Economic Area is the most known since around half a century (European Commission).
Even emerging regions are starting to understand its benefits, reason why it was established
in 2015 the Association of Southeast Asian Nations (ASEAN) Economic Community which
has the intend of promoting the free flow of skilled labour (Association of Southeast Asian
Nations) and this is happening due to the increase in demand for these workers as the own
digital economy intends. However, different thoughts have put a damper in strengthening

these ties, as it is the current case of the United Kingdom wanting to leave the EU, commonly
known as Brexit, which risks the mutual access to these markets, without knowing what its
real effects are going to be. So, the question arises if the countries that decide to leave the
free movement area, assuming here that this implies putting barriers to the entrance of non-
natives, will suffer in terms of growth, development and equality. While this is uncertain,
there have been multiple researches expressing the benefits of free movement, namely
regarding positive outcomes on wages and employment (OECD, 2012, p. 4).

It is natural to question the repercussions that these flows of human capital have in society,
namely in the lives of the natives. Indeed, national security should not be put at risk for freely
opening the borders, being needed some restrictions in place to prevent this. However, there
are times in which these restrictions come mostly from fear, without the right information
backing it, which can undermine the prospects for the progress of a particular society.
Indeed, the present time is marked by the beginning of the “Fourth Industrial Revolution”, in
which both governments and businesses need to foresee potential risks and constantly
adapt to the endless changes (World Economic Forum & INSEAD, 2016, p. v). It is by
accepting that the world is changing with the information and communication technologies
(ICTs) that countries can grow the most (World Economic Forum & INSEAD, 2016, p. v).
But, all sectors of the economy need to be interconnected as it is mainly the “global IT
industry” that is going to provide the new technology for the other sectors, especially for the
government with its adaptation to the “Digital Era Governance”6 (Dunleavy, et al., 2007, p.
2). Thus, there is a big dependence on ICTs (as well as, in the near future, of robotics,
artificial intelligence or quantum computing, for example) throughout all the economy and
6 “Digital Era Governance” is viewed as the progression from the “New Public Management”, in which there is a deep connection with the private sector regarding the implementation of new systems and the presence of egovernment (Dunleavy, et al., 2007, p. 4).

not acknowledging the promoters of these innovations can put a dent in the progress
achieved and the future of the country. Naturally, the progress of a society is normally looked
at from an economic perspective, but a social change also has to accompany it to actually
present results in its development. In fact, Jacobs & Šlaus (2011, p. 98) argue that it is the
unique capabilities of human capital that makes development sustainable in the long-term,
being indispensable for human to be concious and aware of their choices, such as the Social
Development Theory suggests. So, the main focus of policymakers should be the humans
and their exclusive skills as it is the engine for the viable development of societies. Indeed,
the New Growth Theory affirms that knowledge is the motor for economic growth, assuming
that its foundation is not technology but the mechanism behind it which produces unique
creations (Cortright, 2001, p. 2). So, Cortright, J. (2001, p. 25) believes that this knowledge-
based economy is basically a cycle of unlimited ideas and, thus, unlimited growth prospects,
needing, for that matter, the individuals that hold those skills. In fact, it has been argued that
if the innovation capacity is restrained, then productivity is going to be negatively affected
as “productivity growth (…) has been generated largely by advances in technology” (Basu
et al., 2001; Basu, et al, 2003; Gordon, 2004a, 2004b, cited in Chellaraj, et al., 2005, p. 1),
which was why the USA had a 34,7% GDP growth derived from IT industries in 1996, already
taking inflation into consideration (US Department of Commerce, 1998, cited in Pohjola,
2001, p. 270). Moreover, it is regularly undervalued the way that specialised immigration
can help economies, without the need for the usual new cuts or taxes, while boosting it as
it was already mentioned before (New American Economy, 2011, p. 5). Indeed, besides the
benefit of generating jobs and wealth, high-skilled immigrants build important ties between
host and home countries, which is an asset that other competitors do not have as, for
instance, a business relationship can be created without the language barrier (Saxenian,
2002, p. 28). So, immigration and economic development should be thought as
interconnected (Saxenian, 2002, p. 29). In fact, poorer countries have benefited from it as
CEDIS Working Papers | VARIA | Nº 6 | julho 2019

“many goods previously produced primarily by lower-skilled factory workers in the OECD
countries are now produced in less developed countries” (Chiswick, 2005, p. 3). Wadhwa,
V. (2012, p. 542) believes that these nations, which do not have their technological market
as matured, can attract their natives home by being a niche and not full of competitors.
Furthermore, it is often argued that immigration hurts employment opportunities for native
citizens and the fact that STEM graduates completely disrupt the job market does not help
to change this perspective. In fact, Borjas, G. (2005, p. 59) discovered that non-native
doctoral recipients had a negative impact in the earnings of their opposing workers. In the
same line of thought, Kerr, W. (2013, p. 16) assumes that older native employees have a
higher probability of being substituted by younger foreigners in STEM areas due to “higher
elasticities of substitution by age” in these fields. Thus, it was discovered that immigrants
are more inclined to graduate from courses with “quantitative and analytical skills” than
natives, whom prioritize “interactive and communication skills” (Peri and Sparber, 2001,
cited in Kerr, W., 2013, p. 16), dividing both groups even further. This was also demonstrated
by Hibbs & Hong (2015, p. 655) with the use of the Gini Index to show that there is an
increase in inequalities with a higher immigration flow. However, several reports contradict
this view. In 2011, the New American Economy (2011, p. 4) found that there was no evidence
backing it up, guaranteeing that high-skilled immigrants create more jobs in the economy
and that they have a bigger burden in taxes than benefits received, while also consuming
and investing more, thus, not undermining the rate of employment of native-born citizens in
the USA. Kahanec & Zimmermann (2014, p. 8) also proved the same result as they argued
that more high-skilled immigrants in society will lead to reducing the differences in wages
between citizens with different skills. So, these authors confirmed that there is a negative
relationship between inequality7 and specialised migration (Kahanec & Zimmermann, 2014,
7 In this dissertation, by inequality it is meant inequality in wealth or income and not regarding any social phenomenon.
CEDIS Working Papers | VARIA | Nº 6 | julho 2019

p. 9). And, although nowadays information is easily disseminated and, thus, new inventions
as well, the region with the breakthrough has a competitive leverage compared to the rest
of the world (Chiswick, 2005, p. 4). So, the usual argument that high-skilled immigrants take
the jobs of natives is often overrated as it is demonstrated by the testimonial of Bill Gates in
Congress in 2008, in which he declares that “H-1Bs have special, innovative skills and that
technology firms on average hire five additional employees to support each new H-1B
worker” (National Foundation for American Policy, 2008, cited in Doran, et al., 2014, p. 1).
Furthermore, the Compete America Coalition has estimated that about 500.000 jobs would
not be created in 2014 as a result of the limit of visas granted each year, being necessary a
reform of immigration policy, in order to continue being a global leader (Microsoft
Corporation Blog, 2014). Even though tech companies sponsor these specialised migrants,
in the USA, there are still a lot of restraints in getting a visa, namely due to the “per-country
limits”8, which means that Chinese and Indian immigrants face a lot more pressure in getting
the right to stay permanently compared to smaller countries (Smith, 2017).
3. Quantitative Analysis
The analysis done in this section is divided into two parts. Firstly, it is going to be studied
the impact that highly skilled immigrants have in technological innovation. Secondly, it is
going to be estimated the way that high-skilled immigration influence the development of
societies, namely through inequality. In order to do that, it is going to be explained the data
and methodology used, which has its foundation in past studies done by some of the authors
8 This limit imposes that there is a maximum of 7% of green cards granted for each country, no matter the dimension and population of it (Smith, 2017).

cited, and the conclusions that can be taken from that analysis, while taking into account
possible limitations that may exist.
3.1. Analysis done by main authors:
Over the last decades, there has been some research dedicated to this subject. Indeed, the
New America Economy (2011, p. 15) used a reduced-form regression to estimate the impact
of immigration in the employment of US-born citizens, with state and year as fixed effects.
Adopting a Two-Stage Least Squares (2SLS)9, the main findings were that employment
rates got higher with immigrants having a higher educational level (New American Economy,
2011, p. 17). On the other hand, Kerr & Lincoln (2010, p. 486) decided to adopt a reduced-
form model to show the effect of immigrants admitted to the USA with the H-1B visa on
science and engineering (SE) employment and innovation, while taking into account the
dependency of the city on this visa program with an interaction term. This author concluded
that “a 10% growth in the national H-1B population corresponded with about a 0,5% higher
growth in total SE employment for each standard deviation increase in state dependency”
(Kerr & Lincoln, 2010, p. 475). Furthermore, Hunt, J. and Gauthier-Loiselle, M. (2010, p. 34)
determined that there was a growth of 9 to 18% in patents per capita with an increase in 1%
of foreign college graduates by doing a probit regression (estimating the probability), while
controlling for “field of study of the highest degree, the highest degree and demographic
variables”. Contrarily, Niebuhr, A. (2006, p. 7) uses R&D personnel, with a lag of 1 year, to
estimate its impact on patent applications, taking into consideration the Diversity Index10 and
9 It was assumed that immigration share was endogenous and, thus, there would be a bias. So, the number of immigrants in the population was used as an instrument. 10 This index is based on the share of foreign employees on the total of employees (Niebuhr, 2006, p. 5).

the following control variables: ratio of service to manufacturing employment, number of
R&D staff at universities and polytechnics per inhabitant, the employment shares of small
and large firms, region type and share of high-skilled employees in total employment. Also
using patent applications as a proxy to innovation in Europe are Ozgen, C., et al., (2011, p.
10), who decided to use an instrument for immigration to estimate its impact on innovation.
So, the distribution of McDonald’s restaurants was the one chosen as an international
company, while controlling for “average population, GDP growth rate, regional specialisation
in services/industry ratio, stock of human capital in S&T fields in the regions”, which resulted
in evaluating that it is the differentiation between immigrants that significantly impacts
innovations (Ozgen, et al., 2011, pp. 14-16). Regarding the measurement of inequalities,
Kahanec & Zimmermann (2014) decided to use the Gini coefficient to estimate the
relationship with high-skilled immigration. For that matter, they decided to use an Ordinary
Least Squares (OLS) regression, accounting for share of postsecondary or higher
education, share of foreign labour force inflation rate, share of population 15-64 years of
age, unemployment rate, women’s unemployment rate, participation rate, women’s
participation rate, share of labour force in agriculture, government size and GDP per capita
(1000s USD) (Kahanec & Zimmermann, 2014, p. 4). This resulted in estimating that
“inequality decreases with a higher labour force quality” (Kahanec & Zimmermann, 2014, p.
9). On the other hand, Hibbs & Hong (2015, p. 656) contradict this finding by using a different
methodology as they came to the conclusion that immigration has a negative impact in
inequality. These authors decided to see the changes in the Gini coefficient by dividing
immigrant inflow by population in a certain metropolitan area and year, while taking into
account the manufacturing share and college-graduate share (Hibbs & Hong, 2015, p. 654).
3.2. Data used:

Estimations in social sciences deal with various challenges, namely the difficulty in gathering
all the data required for the evaluation as it concerns humans. So, although the total number
of immigrants for each country and each year is known, the same does not apply to the
education level of these. In fact, Kerr, et al., (2017, p. 4) discusses precisely the deficiency
of migration data and the unsuccessful attempt of researchers in encouraging governments
in getting the necessary data, as it has implications in the policies adopted. In order to
overcome this obstacle, it was assumed that employment rates by place of birth and
educational
11
attainment (25-64) would be a suitable proxy for high-skilled immigration as it demonstrates
those specialised migrants that are actively contributing to society. This data was extracted
from the OECD Statistics for a sample of 31 countries from 2000 to 2015 (Appendix B shows
the complete list of countries), having been selected only the data from high educational
attainment and foreign-born.

Graphic 1: Average employment rates of high-skilled immigrants for some specific countries (%)
(Data Source: OECD Statistics)
As it can be seen by graphic 1, the average employment rates of high-skilled immigrants in
almost two decades has been relatively high in industrialised countries. This sample shows
that each nation chosen has a rate above 70%, with more than half of these having a rate
higher than 80%. The fact that the average rate does not change drastically from one
advanced country to another demonstrate the constant fight for specialised migrants, in
order to get the economic advantage. Indeed, graphic 2 displays the data compiled for all
the countries and years, in which we can see that the median is, approximately, 78%, while
25% of the sample is in between the rates of around 81% and 91% (fourth quartile).
However, it also reveals that there are outliers below roughly the 61% rate, which could be
explained by the lack of support from the local community to integrate these individuals,
assuming, of course, that we are dealing, in these cases, with immigrants that do not need
a job to get the visa to enter the host-country or that lost their job recently.

On the other hand, it was already mentioned that the technological revolution had a deep
impact around the world, so it is only normal that this effect is displayed through the years
with the continuous appearance of new technologies. Thus, patents applications (residents)
was chosen as the variable capable of capturing technological innovations, such as multiple
researchers have previously done, as patents represent the right for the development of an
idea (World Intellectual Property Organisation). The data was obtained from the World Bank
– World Development Indicators from 2000 to 2015 for advanced economies (the list of
countries can be seen in Appendix B). This period shows the advancements in the industry
with the average patent applications going from around 11.000 in 2000 to approximately
14.300 in 2015, with a slight decrease in 2007 due to the economic crisis that affected the
world, as shown in graphic 3. However, after the financial world crisis in 2007, the number
of inventions increased significantly as there was the need for the improvement of all sectors

of the economy. Furthermore, graphic 4 demonstrates the privileged position of the United
States of America with the highest average of patent applications of around 13%, which
illustrates one of the reasons for this country to be a dominant nation.
Moreover, the development of societies can be viewed through multiple and distant
perspectives, from an economic one to a social one. In order to measure this, a variable
often used is the Gross Domestic Product of a nation, but it was decided to use the Gini
Index in this case as it demonstrates the inequality that exists in a particular society through
the dispersion of income or wealth (OECD, 2006). Although there has been contradictory
research regarding the impact of inequality on economic growth, the International Monetary
Fund (2014, p. 26) has concluded that decreasing inequality leads to sustainable growth,
but extreme income or wealth equality will do the opposite. Therefore, this data was
extracted from the World Bank – World Development Indicators for 31 countries, which can
be seen in Appendix B, for the period between 2000 and 2015. As it can be perceived by

graphic 5, inequalities have been rising throughout the years as the average Gini coefficient
went from around 31,411 in 2000 to approximately 32,9 in 2015. This increment could, of
course, be due to the economic crisis that affected the world in 2007 as higher taxes and
more unemployment took its told in the wealth of individuals, which is precisely shown by
the values above the line in the graph during that period.

As it was mentioned before, multiple authors used instrumental variables (IV) for their
analysis as it was thought that high-skilled immigration had endogeneity issues. Therefore,
the methodology chosen in this dissertation for the first part of the analysis is mainly based
on the work of Ozgen, C., et al., (2011) with the use of an IV model to understand the impact
of specialised immigration in technological innovations, assuming that this last one could be
captured in patent applications. The main problem regarding measuring the effect of
immigration in innovation is the fact that what attracts the most specialised migrants to a
specific territory could be the benefits brought by innovation itself as it stimulates the
economy, in terms of innovation centres and higher incomes, for instance (Ozgen, et al.,
2011, p. 10). It was discussed previously that the number of McDonald’s restaurants was
thought to ascertain the openness of a society and, thus, the residence of immigrants,
without having that much connection with innovation (Ozgen, et al., 2011, p. 10). Therefore,
and going with the same reasoning, it was assumed that the attitudes towards immigration
would reflect the openness of the nation, having been discussed by Roots, et al., (2016, p.
2) the measurement of this by using social surveys.
So, the instrument selected was the variable ‘Immigrants make country worse or better place
to live’ from the European Social Survey, circulated every two years from 2002 to 2016,
which was used for most countries (Appendix B has the full list of countries). By
instrumenting highskilled immigration with this exogenous variable, it is presumed that the
potential endogeneity bias is dealt with. A favourable attitude towards immigrants would
supposedly make the region more prone to accepting them, especially in terms of the policy
adopted without as much restrictions, while not having a direct effect on patent applications.
This variable, which is expressed as a percentage of the total number of responses,
contained answers from 0 (worse place to live) to 10 (better place to live), having been
extracted just this last result as it expresses the unambiguous opinion of the citizens. For
the case of the United States of America, this data had to be selected from the General
CEDIS Working Papers | VARIA | Nº 6 | julho 2019
21
VARIA
Julho
2019
Nº 6
Social Survey, in which there were only the years 2004 and 2014 available. In order to have
homogeneous data for this variable, it was necessary to convert it to a percentage by
dividing the actual answers by the total of cases. On the other hand, there was the need to
take into consideration the factors that can also impact patent innovations, in order to control
these. The Innovation Policy Platform argues that being able to get financial means is
fundamental for the creation of innovation, which depends on the funding provided either
privately or publicly, as well as the policy framework, markets and competition, as the
economic environment defines how prosperous innovative minds can be by defining
instruments that can preserve its interests. Thus, the following variables were treated as
control variables, so that the economic system would not bias the final results: New
Businesses Registered (number), Gross Domestic Product (GDP) per capita growth (annual
%), Total Researchers (Full-time equivalent) and Gross Domestic Expenditure on Research
and Experimental Development (GERD) as a percentage of GDP. The data was extracted
from 2000 to 2015 for 31 countries, being the first two from the World Bank – World
Development Indicators and the others from OECD Statistics.
Therefore, the specification of the model used with fixed effects is the following:
𝑥1𝑖t-1= γ𝑖 + δ1IV𝑖 t + δ2𝑥2𝑖𝑡−1+ δ3𝑥3𝑖𝑡-1+ δ4𝑥4𝑖𝑡+ δ5𝑥5𝑖𝑡-1+εit (I)
ln( 𝑦𝑖𝑡)= 𝛼𝑖 + 𝛽1𝑥1𝑖t-1 + 𝛽2𝑥2𝑖𝑡−1+ 𝛽3𝑥3𝑖𝑡-1+ 𝛽4𝑥4𝑖𝑡+ 𝛽5𝑥5𝑖𝑡-1+uit (II)
Although it is demonstrated the two stages of the IV analysis12, specific software made it
possible to do it in one single step, so as to have the right standard errors. So, 𝑦𝑖𝑡 is
patents applications (residents) in country i at time t, 𝑥1𝑖𝑡-1 is employment rates by place of
birth and educational attainment (25-64) in country i at time t-1, which was assumed to be
12 The second stage uses the predicted values of 𝑥1𝑖𝑡-1, obtained through the first stage with an OLS regression, to estimate the dependent variable.

correlated with the error term εit, being necessary, therefore, to be instrumented by IV𝑖 t ,
which is immigrants making country worse or better place to live in country i at time t.
Furthermore, 𝑥2𝑖𝑡−1 is the New Businesses Registered (number) in country i at time t-1,
𝑥3𝑖𝑡−1 is the Total Researchers (Full-time equivalent) in country i at time t-1, 𝑥4𝑖𝑡 is the
Gross Domestic Expenditure on Research and Experimental Development (GERD) as a
percentage of GDP in country i at time t, 𝑥5𝑖𝑡−1 is the Gross Domestic Product (GDP) per

1 and γ𝑖, δ1, δ2, δ3, δ4, δ5, 𝛼𝑖, 𝛽1, 𝛽2, 𝛽3, 𝛽4, 𝛽5 are unknown parameters.
It was decided to log the dependent variable in order to improve the model fit, making it also
more suitable to interpret the final results. On the other hand, it was presumed that
employment rates by place of birth and educational attainment (representing high-skilled
immigration), new businesses registered, total researchers and GDP per capita growth
needed a lag of one year as each one had a memory that might affect the t period. It is
shown in table 1 the summary statistics of each variable as follows.

3.3.2. Second part of analysis
As it was seen above, the main authors researching this topic decided to use the Gini Index
to explore the question of the development of societies through the presence of inequality
in a society. Indeed, it was assumed that the more developed societies would display lower
CEDIS Working Papers | VARIA | Nº 6 | julho 2019
24
VARIA
Julho
2019
Nº 6
levels of inequality compared to developing nations and vice-versa. For that matter, it was
decided to go with the same approach, in which it was tested the impact of high-skilled
immigrants in inequality with the use of the Gini Index in an OLS multivariate regression.
The various contradictory research found made it crucial to think about the possibility of
creating a new variable with a quadratic transformation regarding high-skilled immigrants13,
in order to capture the distinct effects. Just as in the first part of this analysis, employment
rates by place of birth and educational attainment is considered as a proxy for highly skilled
immigrants for lack of superior data in this multivariate regression. Furthermore, basing this
model on the work done by Kahanec & Zimmermann (2014), it was decided to use Gross
Domestic Product growth (annual %) and Urban Population (% of total) as control variables,
so that possible external circumstances would not influence the real impact calculated.
These two variables were selected from the World Bank – World Development Indicators
for the countries explicit in Appendix B and from 2000 to 2015.
Thus, the model used with fixed effects is subsequently:
𝑦𝑖𝑡= 𝛼𝑖 +𝜌𝑦𝑖t -1+ 𝛽1𝑥1𝑖𝑡+ 𝛽2(𝑥1𝑖𝑡)2+ 𝛽3𝑥2𝑖𝑡-1+ 𝛽4𝑥3𝑖𝑡 (III)
Accordingly, 𝑦𝑖𝑡 is the Gini Index (World Bank estimate) in country i at time t14, 𝑥1𝑖𝑡 is e
mployment rates by place of birth and educational attainment (25-64) in country i at time t,
𝑥 2𝑖𝑡−1 is the Gross Domestic Product (GDP) per capita growth (annual %) in country i at
time t -1, 𝑥3𝑖𝑡 is the Urban Population (% of total) in country i at time t and 𝛼𝑖, 𝜌, 𝛽1, 𝛽2,
𝛽3, 𝛽4 are unknown parameters. Furthermore, it was introduced a lag in the dependent
variable Gini Index (% of total) as it was believed that there is a memory that could affect
the year t, which was the same for GDP per capita growth with the inclusion of a lag of one
13 This new variable was created by squaring employment rates of high-skilled immigrants 14 At the right side of the model, the same variable appears at time t-1.

period, because of the assumption that it would not produce effects in that same year. Table
2 specifies the summary statistics of each variable used in the model.
Table 2: Summary Statistics of model III
3.4. Statistical Results:
Regarding the first analysis done, its conclusion is that there is statistical significance in the
link between patent applications and employment rates for highly skilled immigrants, in
which a higher number of specialised immigrants increases the amount of patents. As it can
be seen by table 3, the results for model 2 are already statistically significant without the use
of an instrument (OLS estimation, naïve in this case as it seems to be biased), but
instrumenting high-skilled immigrants in the final model proved to be a better fit as it
increased confidence levels to 98,5% and reduced bias, which increased the suspicion that
there is, in fact, a causation in both ways, meaning that places with a higher technological
innovation would also attract more specialised migrants. Although it is not possible to test
CEDIS Working Papers | VARIA | Nº 6 | julho 2019
26
VARIA

2019
Nº 6
the exclusion restriction of the instrument, as in effecting patent applications only through its
impact on highly skilled immigrants, this instrument proved to be relevant as it was
statistically significant in the first stage of the Two-Stage Least Squares (2SLS) Regression
at a 99,4% of confidence level.
Table 3: Estimations of model I/II
Thus, it was estimated that with employment rates of 100% there would be around 9% more
patent applications as it can be seen by graphic 6. This result also demonstrates the impact
CEDIS Working Papers | VARIA | Nº 6 | julho 2019
27
VARIA
Julho
2019
Nº 6
it has in society. Putting barriers to highly skilled immigration would slow down the progress
already achieved by advanced economies as the competitive edge would be lost. Thus, this
would mean that about 9% of patents applications would be lost without the employment of
specialised immigrants, consequently impacting the economic development of societies,
which would suffer with deeper restraints to migration. This result is just being demonstrated
by an economic perspective, but it is also important to take into account the positive
consequences that this have from spillover effects. Developed countries are being
characterized as having older citizens as a big part of its population, which do not contribute
actively for the economy and, thus, there is a pressure to have policies in place to aid these
individuals and counterbalance this. In fact, the OECD has predicted that active population
is going to go down by 12% in about 10 years in the European countries (2012, p. 3). So,
specialised immigrants would help balance this demand with their active contribution
towards society, while also connecting the host and home countries with the possibility of
having flows of know-how and money between these.

country worse or better place to live. (Data Source: The World Bank - World Development
Indicators, OECD Statistics, European Social Survey and General Social Survey)
On the other hand, the second part of the analysis resulted in the conclusion that there is,
in fact, a statistically significant link between the economic development of a society and
highskilled immigrants. As it was mentioned before, there has been contradictory views
regarding this effect and the outcome here demonstrates precisely that as it can be seen by
table 4 with the last model being the one with a higher confidence level of more than 95%,
which was also the one adopted (Appendix C displays the normal distribution of the error
term, which goes in accordance with the OLS assumptions). This quadratic transformation
is proof that there is a different impact in society depending on the number of specialised
immigrants employed. Thus, inequality rises as a consequence of lower levels of
employment of migrants until a point in which it changes directions and starts to decrease
due to the higher talent pool. This shift goes according to previous research, the only
difference being that it was not considered a linear relationship in here and, instead, it was
took into account the possibility of both perspectives of its effects being correct.

Table 4: Estimations of model III
Consequently, graphic 7 displays this relationship. The Gini coefficient goes from around
29,6 to around 32,1 when the employment rate of high-skilled immigrants is in between 50
and 81,67%15 approximately, which means that inequality in total rises when these foreign
workers are not employed. As these immigrants contribute considerably to taxes and social
security, this increase in inequality might not be that significant as inequality is relative to a
baseline and if the upper income or wealth grows relatively more than the lower income or
wealth, the final equation will be an increase of inequality, however with an increase in the

the following expression: 𝑥1= - 𝛽1 / (𝛽2 * 2) = -0,3740591/(-0,00229*2) » 81,67

quality of live. On the other hand, the situation changes after the turning point of 81,67%, as
higher employment rates will decrease inequality. Although the changes in the coefficient do
not seem that significant, the reality could be different. Thus, if there are not at least 81,67%
of highskilled immigrants employed, this is going to manifest itself in inequality, just as
common sense suggests. Of course, in most countries, a work placement is needed in order
to be allowed to stay in a country and get the visa. But, for those that have the intention of
being entrepreneurs that is not the case. Furthermore, higher economic inequalities are
often correlated with more poverty and, thus, it can put more pressure in the government to
handle crime prevention and public health, which would restrain economic growth. So,
immigration policies needs to take this into account and make sure that the right conditions
are in place to not deepen inequality between citizens, which would compromise the
sustainable development of societies.

3.5. Limitations:
In this section, it is going to be explained some of the flaws that the analysis in question
carries. Firstly, regarding the initial one, not having data about high-skilled immigrants for
each country and year is one of the main limitations of this research as it is its central focus,
being necessary to counterbalance this with the use of employment rates of specialised
migrants, which does not reflect exactly the same effect. Additionally, the country in which
there was the application for the patent may not be the location experiencing the highest
repercussions of it, as it was also mentioned by Ozgen, et al. (2011, p. 7). Furthermore, the
fact that the European Social Survey just happens every two years makes the sample for
model I have less observations and, thus, less statistical power, which is the same for the
General Social Survey, in the case of the USA, that only has data for two years in a period
of a decade and a half. Moreover, in past research, the diversity effect is also taken into
account, namely in the analysis done by Ozgen, et al., (2011, p. 9), in which this
fractionalization index captures the probability of belonging to different cultural backgrounds.
However, it would not be feasible to do so in this case, because of the complexity of the
calculations as it uses the Herfindahl index of concentration (Ozgen, et al., 2011, p. 9). On
the other hand, the second part of the analysis also has the problem regarding the data for
high-skilled immigrants. Naturally, this may compromise the conclusions taken from it as the
data is referring to the employment rates of talented immigrants and not the own individuals.
Although it is expected for the overall results to be the same, the predicted outcomes could
change. Furthermore, it is only tested its impact in the development of a society through the
perspective of income or wealth inequality, while many other factors are not being taken into
account. Indeed, the focus has been only in differences in the labour supply and not in the
changes in spending that inevitable comes attached to it, which could have repercussions
CEDIS Working Papers | VARIA | Nº 6 | julho 2019
32

Nº 6
on the impact already mentioned, just as Hibbs & Hong (2015, p. 7) also note in their
analysis.
4. Further Discussion and Recommendations:
As it was seen before, it is in our interest to advocate for a friendlier immigration policy and,
for that matter, it is going to be enumerated a few approaches for that purpose. In this
discussion, it is adopted a “realistic morality”16, which suggests that immigration policy has
to take into consideration the pressure that this flow exerts on the native citizens as “a
morality that requires people to sacrifice what they regard as basic interests (…) is bound to
fail as a guide of action” (Carens, 1996, p. 163). Although it is advocated a more liberal
immigration policy, limits for open borders can be put in place when national security is at
risk and basic human rights are endangered, which is the case with the prevention of
terrorists attacks.
Indeed, the birth place can be considered to be the lottery of life (Shachar, 2009). It does
not depend on a concrete action of any person to be born in a wealthy country or in a wealthy
family. This might even be considered as a first injustice, for which no one can be
accountable. And to try to solve the problem of a just society that gives a fair opportunity to
everyone, independently of the birth place, John Rawls (1999) makes the philosophical
suggestion, through his two principles of justice, of how a well-organised society can raise
the position of the worst-off group, group that did not have the same luck in life17. This same
16 This is seen as the approach to close the gap between the “ought” and the “is”, as in to apply the ethical standards to public policy (Carens, 1996, p. 157). 17 “Two principles of justice. First: each person is to have an equal right to the most extensive scheme of equal basic liberties compatible with a similar scheme of liberties for others. Second: social and economic inequalities

reasoning might be extended from a particular society to the relationship between different
nations, so that people are able to have the same equality of opportunity, at least the ones
who feel that are entitled to it, such as high-skilled immigrants. Also, the argument that
immigrants might distort the national identity and traditional culture of a community is
questionable, as most countries nowadays have immigrants and, thus, the very own
definition of the term “national identity” does not uphold the purpose intended.
So, sensible rules need to exist without compromising the economic prospects of a particular
society. But, it is the overall mentality of the citizens that sometimes push the acceptable
limits as racial discrimination and xenophobia seem to plague and influence the more
restrictive immigration policies, as it was the case when the current President of the United
States of America Donald Trump mentioned that “open borders means crime” (The
Economist, 2018) (Appendix D exhibits an extract from the mentioned article). Thus, it is this
way of thinking that needs to change. However, the reality is that this is extremely difficult
and a long-term process. So, more practical and realistic measures need to be put into
place.
On the other hand, it should be noticed that, in this new millennium, with the changing global
economic landscape, Asian countries are developing very consistently. China, for instance,
intends to be not only the factory of the world but also the worldwide heart of innovation (Bel,
2015, p. 34). According to a report of PricewaterhouseCoopers (2009, p. 2), China is
transforming itself in the world base of research, innovation and development due to the
structural change from a producer country to a society committed to innovation. Moreover,
both China and India, with more or less 1.4 billion people each (Worldometers, 2018), have
a clear population advantage, meaning that the pool of high-skilled innovators is, at least in
principle, much larger than that of developed countries such as the United States of America
are to be arranged so that they are both (a) reasonably expected to be to everyone’s advantage, and (b) attached to positions and offices open to all” (Rawls, 1999, p. 53).

Nº 6
or the European Union. It might mean that for western developed countries to compete in
the future global economy, they should tackle the issue of allowing qualified immigration,
and therefore, to promote faster technological innovation or the competitive edge will be lost.
Thus, over the years, several politicians in the USA have proposed to create a visa specially
designed for foreign entrepreneurs, but it has not been successful so far (Wadhwa, 2012, p.
967), which is not the case in other countries of the world, such as the United Kingdom, for
instance, which has this kind of permit (UK Government, 2018). Wadhwa, V. (2012, p. 981)
believes that there should be no quota restriction based in the country of origin as it is not
fair for states with a larger population and, thus, a higher talent pool, as it is the case of
China and India, in comparison with those with less citizens. This would mean that the
process is solely based on the skills of immigrants. In fact, the Congressional Budget Office
(Nonpartisan Analysis for the U.S. Congress) has estimated in 2014 that a change to the
USA’s visa program would have positive repercussions, namely the increase of revenues in
118 billion dollars during a decade with the growth of the labour force. With this in mind, it is
also important not to forget the role that families play, being fundamental not to put added
restraints to the unification of families. So, giving permission to the spouse and children to
go to the host country should also be kept in mind.
Moreover, policymakers should look at the bigger picture and strategically plan the course
of action as it is necessary to take into account the best conditions to attract and retain these
immigrants, because it is not only the permission to stay that counts but also their quality of
life. So, helping them to integrate into society by organising explicit programs with the
community would encourage this process, which would also endorse respect among the
different ethnic groups. Furthermore, another measure would be to have specific workers
dedicated to gather information about the progress and productivity of high-skilled
immigrants to understand the real impact that it has in the economy, in order to actually
make special schemes dedicated to it.

5. Conclusion:
International flows of people have always been a controversial topic in policy debates as
there is not a clear optimal solution that would not benefit one side more than the other.
Indeed, worries with national security and identity can influence the opinion regarding
opening the borders of a nation, reason why we have been witnessing more restrictive
immigration policies around the world. Although it is necessary to take this into account, it is
also important to understand the benefits that come with migration as it is the only way to
make an informed decision without bias affecting it. This prejudice can harm societies
without the citizens even realising it. But, from a normative perspective, the place of birth of
a particular citizen is pure luck, which justifies the search and, thus, the permission to obtain
better work prospects and a higher quality of life, namely in more advanced societies. So,
immigrants have been a constant in these nations as the demand for skilled human capital
has been increasing over the years due to the perpetual change in society as a result of
technological innovations. However, it is frequently undervalued the impact that these high-
skilled immigrants have in the progress of technology, which also has repercussions in the
improvement and growth of nations.
On the other hand, almost every sector in society is being affected by technology, which
involves adapting to the changes that are constantly happening. For that matter, more and
more specialised workers are needed, independently of their nationality and background.
Naturally, tech companies have understood this and are competing with each other to attract
and retain the best of the best, reason why these organisations are willing to sponsor
immigrants for their visa as they know the competitive advantage that it would bring,
especially those in STEM fields. These individuals have, most of the times, skills that are
treasured, skills that cannot be found elsewhere as it is their background and individual
experience that shapes it. So, these unique talents allows them to look and find niches that
CEDIS Working Papers | VARIA | Nº 6 | julho 2019
36

2019
Nº 6
could escape the untrained eye, which explains why there are several entrepreneurs
immigrants and why multiple big tech companies nowadays have one of their founders as
such. However, recent worldwide nationalist promulgation threats to undermine this trend of
technological accomplishment, which can stagnate the development of societies. Indeed,
the research done in this dissertation with the adoption of an instrumental variable model
allowed to come to the conclusion that there is a statistically significant and positive
relationship between high-skilled immigrants and technological innovations. So, putting
barriers in the entrance and permission to live in a particular country to talented immigrants
will decelerate the growth of innovations by approximately 9%.
Furthermore, there are various theories that believe in the connection between the three
factors: high-skilled immigrants, technological innovation and economic development. In
fact, the New Growth Theory presumes that it is the knowledge that is behind these
innovations that allows for prosperity to emerge and, over the years, there has been
evidence of an increase in productivity with the adoption of technology in organisations,
boosting the economic prospect of societies. So, this becomes a cycle. More specialised
immigrants modernizes environments and all its sectors. However, the question about its
impacts in the natives can appear, being necessary to see the advantages and
disadvantages towards them. Although, there is the usual argument that immigrants take
the jobs of the natives, there are several reports that contradict this view, as far as creating
even more opportunities for them, while supporting a big part in taxes and social security
which, in turn, helps to contradict the ageing trend that exists in developed countries. The
conclusion of the second part of the analysis done in here expresses both perspectives. The
multivariate quadratic regression allowed to derive that high-skilled immigrants would need
to have an employment rate higher than, approximately, 81,67% to not increase income or
wealth inequalities. But, more specialised immigrants employed suggest less income or
CEDIS Working Papers | VARIA | Nº 6 | julho 2019
37
VARIA
Julho
2019
Nº 6
wealth differences between citizens and, as inequality has been associated with stagnated
economies by some authors, this would stimulate economic development.
Therefore, it is necessary to understand the consequences of restraining the flow of talented
migration as it is a subject that can sometimes be overlooked, which could be particularly
damaging for the competitive edge that advanced nations have. So, less restrictive
immigration policies have been advocated by tech companies namely in the United States
of America as it is becoming clear to them that their country is losing its position at the top
for emerging competing nations, such as India and China. Facilitating the visa process and
allowing for different types of permissions, such as a visa solely for entrepreneurship, would
smooth the overall movement, without interfering with national security. But, it is necessary
to have better data regarding high-skilled immigration in order to have a proper debate and
so that policymakers can make informed decisions based in accurate research.

7.1. Appendix A: The case of Microsoft Corporation
The computer revolution originated a true “Fourth Industrial Revolution” in the beginning of
the 21st Century, namely artificial intelligence (AI) as well as robotics associated with the
general use of the Internet of Things are changing dramatically industrial production,
technology development and even labour relations (World Economic Forum & INSEAD,
2016, p. v). Thus, in order to understand what actually happens inside the IT industry, it was
decided to look deeper into the case of Microsoft Corporation. This American corporation
specialises in computer software systems, gaming, mobile phones, among many others
(Britannica, 2018), being considered to be one of the top 25 technological companies of the
world, raking 3rd in 2017 by Forbes. Founded in 1975 by Bill Gates and Paul Allen, it has
an enormous influence around the world, using this leverage to advocate for some decisive
debates, namely about immigration in the USA as this subject not only influences millions of
people and the economy, but also affects the company itself and its business (Smith, 2018).
Indeed, Brad Smith (2018), the Chief Legal Officer (CLO) of Microsoft, believes that the
achievements of this company are due to immigration as it attracts the best talents from
around the world. The ongoing debate about migration is an important issue for Microsoft
Corporation, coming directly from the top as its current Chief Executive Officer (CEO) is
Satya Nadella, an Indian immigrant that went to America to get higher education in a STEM
subject (Bloomberg, 2017).
Indeed, many of the employees that work at this organisation have, or are in the process of
getting, green cards, but the uncertainty that revolves around the visas makes these
migrants unsure about their future (Smith, 2018), as was the case when, in 2017, the block

to enter the USA for 90 days for citizens of countries such as Iran and Iraq was announced,
in which help was offered by Microsoft to the 76 employees with a temporary work visa that
were in these conditions (The Seattle Times, 2017). Despite the hindrances, the number of
H1-B visa applications approved by Microsoft increased from 1,145 in 2016 to 1,479 in 2017
as the demand for talent was not fulfilled by natives (Statista, 2018, cited in Business Insider
UK, 2018). In 2017, Microsoft Corporation was ranked number 9 in the list of patents
creations with 2.601 patents produced, an increase of 1,7% from the year before (Intellectual
Property Owners Association, 2018), having been estimated that, in 2016, each employee
produced 725.403 U.S. dollars of revenue annually (Statista, 2018). So, from the 77.829
employees in the USA (Microsoft Corporation, 2018), there were 15.000 who were
dependent on a work visa in 2017 (IT Showcase Blog, 2018), which would mean that these
immigrants generated around 906 millions just in one month18.
Moreover, emerging countries are becoming a powerful competition in the tech industry.
Indeed, by integrating the World Trade Organisation in 2001, China has agreed to promote
respect for patent rights as well as prohibiting illegitimate technology transfer, thus, creating
a “level playing field” between China and other global competitors (European Commission,
2018) and India, for instance, has a fast-growing biotech sector that is growing worldwide
(Rezaie, et al., 2012, p. 4). So, these countries are trying to bring their talented natives home
with the promise off multiple benefits, being necessary for advanced countries to take this
into account if they do not want to lose the competitive edge.
18 Assuming that the estimation would be the same for 2017.

7.3. Appendix D: Extract from The Economist’s article
“America could learn from the EU’s open borders
Only libertarians advocate completely free movement, writes Will Wilkinson, yet there is
much to be said for a degree of openness in immigration policy
(…) Steve King, a hardline anti-immigration congressman from Iowa, maintains that
Americans “face an identity crisis, as open-borders politicians are seeking to ‘fundamentally
transform’ our nation through mass immigration policies". And then, of course, there is
President Donald Trump. “The Democrats are for open borders, which means crime,” Mr
Trump recently opined. “It's not a question of, like, what do you think it means. Open borders
means crime.”
You may not be shocked to learn that Mr Trump inverts the truth. Democrats are not
principled advocates of open borders and free movement. Immigrants are less likely to
commit crimes than native-born Americans. And there is definitely a question of what “open
borders” means.
Out of the mouths of Messrs King, Miller and Trump, “border” basically means “the purity of
the national stock” and “open” basically means “defilement.” “If we don't have borders,” Mr
Trump has said, “we don’t have a country.” As it happens, America does have borders, and
is a country. What Mr Trump means, and what his supporters hear, is that a country is a
people of a unified ethnicity, and a drift towards a different, more varied complexion must be
stopped.
This confusion of immigration policy for demographic social engineering has led Mr Trump
to split up families, jail toddlers and terrorise immigrant communities.

But it is important to see that demographic change is only incidentally a matter of “borders”.
If ethno-nationalist population control is the policy goal, then the presence of an already
large multicultural population and declining white birth rates are bigger obstacles than
immigration.
(…) As the EU makes plain, the notion of “open borders” is not all or nothing. Legal entry
and residency can be open to citizens of some countries but not to others. The French are
free to waltz into Spain, but Moroccans aren’t. Moreover, it is a mistake to conflate a
permissive immigration policy with “open borders”, since selective openness is compatible
with overall restrictiveness. A border that is entirely open to the citizens of a few nearby
countries can be, on the whole, less porous than one than that is open to anyone anywhere
who ticks the right boxes. Immigration policy can’t shut down streams of human traffic.
Instead, free and prosperous liberal societies require clear rules that respect and regulate
inevitable migration flows.
An open border between Mexico and America, on the model of the open border between
Spain and France, could fix the problem. It would bring peaceful and productive labour
migration within the rule of law, reduce exploitation and abuse by employers and human
smugglers, and more speedily shrink the gap in living standards that, more than anything,
draws Mexicans north.
Aside from a handful of libertarian idealists, no one is proposing to open borders everywhere
to everyone. But to defend the existing liberal order is to stand up for multicultural societies.
And according to Gallup, a record high 75% of Americans now say immigration is a good
thing. This shift in opinion, should it last, could open up new opportunities for liberalising
immigration reform. A sane debate is impossible, however, if the public mind continues to
be polluted by nativist misdirection.” (The Economist, 2018)
