Abstract
This paper examines the migration and labor mobility in the European Union and elaborates on their
importance for the existence of the EU. Against all measures of success, the current public debate
seems to suggest that the political consensus that migration is beneficial is broken. This comes with
a crisis of European institutions in general. Migration and labor mobility have not been at the origin
of the perceived cultural shift. The EU in its current form and ambition could perfectly survive or
collapse even if it solves its migration challenge. But it will most likely collapse, if it fails to solve
the mobility issue by not preserving free internal labor mobility and not establishing a joint external
migration policy.

1. Introduction
Peace and prosperity have been the guiding objectives of the European integration process. Although
challenging, free labor mobility has been among the core principles from the beginning. It was
understood that the free movement of people would need a much longer path, but it would
nevertheless be unavoidable to meet the preferences of the people, the demands of the economies and
the political vision for Europe without it. For decades, the enlargement and integration process has
been moving ahead. While slowing down at times, or being delayed, it also experienced larger jumps,
as it happened for instance after the end of socialism. Over the years, the number of countries involved
and the integration ambitions have increased substantially. The quantity and quality of European
country-members have exhibited a bright perspective for the continent, at all political, social and
economic levels. European hearts and brains were on the same track.
But looming EU-skepticism1 among the citizens in the member-countries with the larger
challenges of the integration process became transparent as in the case of the Maastricht economic
criteria, the economic shocks caused by the Great Recession and the rise of anti-globalism. The
troubles around the Euro rose with the helpless actions of European policy-makers. Therefore, parts
of societies started feeling that they were left behind and wrongly associated this with EU integration.
At the same time, political decisions chose to ignore the economic and social potential benefits of a

the currency.

united Europe. A world-wide cultural shift moved societies from evidence-based policy-making to
evidence-ignoring policy-making. Nationalistic movements, a desire for strict ethnic homogeneity
and anti-European sentiments became stronger and stronger. Brexit is only one of the consequences.
Migration and labor mobility have not been at the origin of the cultural shift. But nowhere can
the puzzle be better demonstrated than on free human movements. Free mobility is a central part of
the human dream; it is cherished individual right. It is beneficial economically because it brings
workers to the place where they are needed most, it creates welfare and fights poverty. With the right
skill mix it contributes to the upward mobility of natives. During the period after the EU-East
enlargement as well as during the Great Recession we saw labor mobility to increase substantially,
as was predicted and hoped for. This mobility enabled also the absorption of asymmetric shocks. In
fact, intra-EU labor mobility during the recent economic crisis helped attenuate disparities in the
levels of unemployment between EU country-members (European Commission, 2016). Neither intraEU cross-country labor mobility nor external immigration caused any considerable economic
problems. Instead they fostered economic development. There was no relevant welfare tourism in
Europe. So against all facts, migration was claimed to cause damages to natives either through losses
of jobs, income or misuse of the welfare state.
An egregious example of mismatch between facts and politics is the Brexit decision. Refugees
are another one. While refugees exhibit challenges for policy-making, they were never a relevant
economic challenge for Europe, even at the relatively high levels of inflows in 2015 and 2016, which
were mostly absorbed by Germany. Despite the apparent rising political wish to strengthen Fortress
Europe, the EU needs more not less migration in the middle and longer future due to a declining and
aging population.
As a consequence, the free mobility of people and labor is under threat, and with it peace and
economic prosperity. Europe is at the crossroads to either collapsing to single, egotistic and
nationalistic states or finding the political resolve to stabilize and continue the integration process.
3
The solution of the migration issue will be largely associated with this outcome and strongly enforcing
it. Namely, without free internal labor mobility and a joint external migration policy, the likely
outcome is the breakdown of Europe.
The paper elaborates on the relevance of labor mobility and migration and provides a brief
history of labor mobility in the European institutional settings. Then the options for Europe's
migration and mobility policy are discussed. The essay ends with conclusions.
2. The Relevance of Migration and Labor Mobility
There is abundant empirical evidence showing huge benefits from free intra-EU mobility and
migration in general, and negative partial findings are scarce.2 But why is labor mobility economically
beneficial? The core answer is that it contributes to an optimal allocation of resources, and therefore
generates higher and better output and more welfare. Hence, migration economics is an important
part of economics in general. Mobility helps labor markets to adjust in disequilibria, particularly after
asymmetric regional shocks. It supports higher total income, creates more jobs, and hence reduces
unemployment. Therefore, the Single European Labor Market project has been top on the European
agenda, although it is still incomplete.
Building up a European tradition, already the Treaty of Paris in 1951 allowed for free
movement of workers in the coal and steel industries. The Treaty of Rome in 1957 established the
right of free movement of workers throughout the European Economic Community. And the
Maastricht Treaty in 1992 established free labor mobility as a core value of the European Union (EU).
Hence, for a long time, the political (and not only economic) consensus has been that fostering growth
through a more efficient allocation of labor can create greater economic welfare, increase European
social-cultural integration, and strengthen a shared European identity.

Zimmermann (1996) and (2014) and Blau and Mackie (2016). The handbook edited by Constant and Zimmermann (2013)
provide further contributions. The following analysis in this section draws also on Constant (2017) and Zimmermann
(2016).

What are the facts? In 2014, among the 15 to 64 years old EU-born, 4% were living in an EUstate other than their birth-country. This is fewer than 15 million mobile people in a Union of about
500 million. Among non-EU nationals migration was much larger with roughly twice as many (28
million) moving. However, there is substantial variation in the stocks of migrants across EU-States.
As a share of the total population migrants exceed 32% in Ireland and Luxembourg, while they are
10% in Cyprus and below 0.5% in Bulgaria, Romania, the Baltic States and Poland. Germany, Spain,
France, Italy and the UK absorb 70% of all EU-citizen migrants and more than 70% of non-EU
migrants. Among native Europeans, about 4% work in an EU member-country other than their
country of birth. Non-EU workers are more mobile with 6.6%. Migrants exhibit lower employment
rates than natives, but these rates depend on the time of arrival in the host country, improving with
additional years of residence (European Commission, 2016b). Jauer et al. (2016) concur that migrants
from outside the EU are typically more mobile also within Europe. Overall, mobile workers in EU28
are young and well-educated following opportunities where unemployment is low. In general, they
have higher employment rates and better job prospects than comparable natives (Constant, 2017).
Unfortunately, the situation in 2017 suggests that the political consensus that migration is
beneficial is broken, or at least it is in substantial danger. But this is not new to the 60 year old EU.
Already before, large-scale international migration was viewed by some as a threat to the sovereignty
of national borders, to economies and their societies. Rising concerns about even intra-EU mobility
in the political debates before and after the Brexit vote in many European member-states suggest
insufficient understanding of the substantial benefits of migration and a convoluted understanding of
the value of the EU in general.
The core of the European migration challenge, however, is not too much labor migration, but
too little mobility of workers. For many decades, and with some exceptions, migration across regions,
within a country and between countries within Europe were even declining. It is well-known that
intra-EU mobility is lower than interstate mobility in the U.S. Traditionally, interregional migration
5
has played a much smaller role in economic adjustments in Europe than in the U.S. Only recently has
Europe become more flexible and mobile, a consequence of the EU Eastern-enlargements and
following the economic divergence of European countries during and after the Great Recession.
Workers in the Eurozone countries have become more mobile than those in countries outside this
zone (Beine et al., 2013; Arpaia et al., 2014). More worker mobility to foster economic adjustments
would be certainly beneficial.
Further forthcoming European labor challenges are technological change (automation), a shift
in demand from low-skilled to highly-skilled workers, population aging and a shrinking of the native
European workforce. Europe therefore faces the rising need to attract appropriate, in particular skilled
labor from the international markets. Given the comparative disadvantage Europe has on the issue,
compared to traditional immigration countries such as the U.S., Canada and Australia, the too low
but still falling understanding of the challenges in Europe causes long-term damages to the
competitiveness of the entire continent.
3. Labor Mobility in the Evolution of Europe
The precursors of the EU go as far back as 1944 when the governments of Belgium, Netherlands and
Luxembourg formed the Benelux Customs Union, while still in exile. The ensuing monetary
agreement, economic union and foreign affairs cooperation of Benelux became the background of the
European integration. European countries that experienced the calamitous 1st and 2nd World Wars
and their visionary leaders understood the power and peace that comes with unity and proposed to
confederate into a European entity. Winston Churchill already spoke about it in 1946. After the
legendary speech of Robert Schuman in 1950, Benelux, along with France, Italy and West Germany
(EU6) signed the Treaty of Paris in 1951, forming the European Coal and Steel Community (ECSC).
Symbolically, ECSC was rendering the raw materials of war into a Community of peace and
reconciliation. ECSC formally opened and started operations in 1953.
6
These successful steps prompted the EU6 to sign the Treaties of Rome on March 25, 1957,
establishing the European Economic Community (EEC) and the European Atomic Energy
Community (Euratom) in order to foster deeper economic cooperation. While EEC was first and
foremost a customs union, Article 3(c) of the treaty already proposed the abolition of obstacles to
freedom of movement for persons, services and capital between member states. The treaties are thus
considered to be the cornerstone of the European Union.
The 1965 Merger Treaty that combined the EEC, ECSC, and Euratom into a single
institutional structure, paved the way to the EU. During this first decade some migration is recorded,
but always in close substitutability to trade. The EEC expanded in 1973 to include Denmark, Ireland
and the UK. The EEC survived the oil crises of the 1970s peacefully and added new member-states
in the 1980s. Greece joined in 1981 as the tenth member. Spain and Portugal joined in 1986 forming
the set of 12. Along with the Schengen agreements abolishing internal border controls,3 the EEC
materialized the free mobility of its people.
In 1986, with the Single European Act the EU12 set off to transform the common market into
a single European market by December 31, 1992, amending the Treaty of Rome and allowing for
political integration, economic and monetary union. This Act was a much needed momentum to the
EU-skepticism and the economic recession of the 1980s. In spite the turbulence caused by the fall of
the Berlin Wall and the ensuing fall of the Soviet Union, EEC remained united, embraced the German
unification in 1990, and was ready to move on to the next level of integration.
The EU12 signed the Treaty on European Union (TEU) as plenipotentiaries in Maastricht in
1992 and created the EU as we know it today. Historians argue that the boost of the EU creation stems
from the uncertainty of the fall of the USSR in 1991, and the unification of Germany in 1990, which
deemed intergovernmental cooperation pertinent. The Treaty brought under one umbrella three

The first Schengen Agreement was signed by Belgium, Netherlands, Luxembourg, France, and Germany in 1985.

pillars: (i) Euratom, ECSC, and EEC (ii) Common Foreign and Security Policy and (iii) police and
judicial cooperation in criminal matters. It introduced the concept of European citizenship, over and
above the national citizenship and along with it the right to circulate and reside freely in the
Community; it expanded and reinforced the role of the European Parliament; and it launched the
economic and monetary union (EMU). EU’s expansion in 1995 to Austria, Finland and Sweden
created the EU15.4
The 1997 Dublin Convention aiming to harmonize refugee policies stipulated that the first
member-country of entry was responsible for the asylum seekers. The idea was to avoid the case
where no member-state accepts responsibility for the asylees who would in turn orbit around the EUstates and file multiple applications.5 The Treaty of Amsterdam (1997), as an amendment to the TEEU
created an employment policy for the Community departing from intergovernmental handling and
bringing the EU closer to its citizens. It incorporated the Schengen agreements and established the
free movement of EU and non-EU citizens.
After the Treaty of Nice (2001) that took care of institutional issues, the Eurozone was created
in 2002 and 12 of the EU15-States adopted the Euro as their new currency.6 The largest expansion of
EU15 came in 2004 with the accession of eight Eastern European countries (the Czech Republic,
Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, Slovenia or EU8) plus Cyprus and Malta. In
2007, Bulgaria and Romania joined the EU25 while Croatia joined the EU27 in 2013. Irrational fears
of mass migration, welfare tourism and domestic labor displacement led many of the EU15 to
introduce 7-years transitional arrangements or the ‘2+3+2’ mobility scheme to the Easterners. Hard
evidence soon showed that the EU15-States that closed their borders experienced adverse outcomes,

The no-border control, free mobility Schengen area includes 26 countries; only 22 are in the EU28. While Ireland and
UK are not part of Schengen, Cyprus, Croatia, Romania and Bulgaria are candidates. On the other hand, Iceland,
Lichtenstein, Norway, and Switzerland are in Schengen (but not in EU28).
5
Dublin’s recasts (in 2003 and 2013) allowed for “readmission” of asylees and used specific criteria for admission. The
EU asylum fingerprint database, EURODAC was created. In light of the refugee surge in the fall of 2015, additional
revisions were proposed.

Denmark, Ireland and the UK opted out. Today, only 19 of the EU28 use the euro as their common currency.

while those countries that opted for early free mobility had beneficial outcomes (Kahanec and
Zimmermann, 2009; 2016). Croatian workers will be under this scheme until 2020, if these EU-states
can prove that restrictions are needed to protect their labor markets. Naturally, Croatia imposed
equivalent restrictions to workers from these EU-States (Constant, 2017).
It became obvious that the enlarged EU needed to amend the TEU, make it simpler and more
efficient. This culminated in the Treaty of Lisbon (singed in 2007 and enacted in 2009) that brought
sweeping reforms. Namely, it changed the EU’s architecture, made new allocations of competencies
between EU and Member-States, and let the institutions legislate. The Treaty is considered a
landmark of free mobility as Article 2§2 specifies: “The Union shall offer its citizens an area of
freedom, security and justice without internal frontiers, in which the free movement of persons is
ensured in conjunction with appropriate measures with respect to external border controls, asylum,
immigration and the prevention and combating of crime.” Both TEU and the Treaty on the
Functioning of the European Union (TFEU) safeguard the right of every EU-citizen to move and live
in another EU-state. TFEU (Article 45) specifically guarantees the free movement of workers in the
EU287 as a fundamental principle. Workers can stay in the host country after their employment ends
and receive equal treatment with nationals.
It is important to note however, that while there is some progress in aligning social and formal
qualifications, health and unemployment benefits or the transferability of skills are still not aligned
among member-states, and constitute impediments to free mobility. Additional mobility limitations
are often in place such as working in the public sector because countries reserve public-sector jobs
for their own citizens. Language barriers and cultural differences add to the divergence between de
jure and de facto mobility.
An analysis of bilateral migration flows by Vargas-Silva (2012) shows that EU-nationals who
migrated to another EU-State in 2010 accounted for 35% of the total migrant stock in the EU as a

whole. This number masks substantial variation among the states. While in Luxembourg and the
Czech Republic they accounted for over 80%, they were only 31.7% in the UK. This is not the mass
migration that some politicians claim.
The June 2016 referendum in the UK resulted in a majority vote to leave the EU. This is an
example, where people dissatisfied with their country’s direction blame the Union. The UK was one
of the first EU-States to open up to the Easterners in 2004 and benefited from them. But UK was also
hit hard from the economic crisis and terrorist acts. It was this, along with political cunning that led
the majority of some socioeconomic strata to vote for Brexit. While there is serious evidence that
upon its exit from the EU Britain will experience negative economic outcomes with respect to trade,
it is not obvious how migration will play out. It is also interesting that the Brexit argument was based
on migration when in fact the UK had the lowest immigrant stock from other EU-States and received
very few refugees (Constant and Zimmermann, 2016).
Unfortunately, the avalanche of refugees to Europe from Syria, Afghanistan, Iraq, etc. that
started in 2014 provided an opportunity to the populist nationalistic parties to surface and threaten
the Union from within. Reacting out of fear and in confusion between migration and terrorist attacks,
some EU-States8 resorted to a special clause of Schengen and closed their borders temporarily,
claiming serious threats to public policy or internal security. A study commissioned by the European
Parliament (2016) calculating the costs to Schengen shows that the introduction of ID-checks would
cost the EU citizens and firms between 7 and 14 billion Euros. Direct cumulative macroeconomic
costs due to the termination of Schengen may even be between 14 to 64 billion Euros per year (0.1%

For example, Denmark (from March, 4 to June, 2, 2016) from the sea and land bordering Germany; Norway (from

2016) an emergency state due to the terrorist attacks in Paris. In the context of Recommendation of the Council on May,

Slovenia and Hungary (from May, 16 to November, 12, 2016) http://ec.europa.eu/ dgs/home-affairs/what-wedo/policies/borders-and-visas/schengen/reintroduction-border-control/index_en.htm.

- 0.4% of EU GDP). Lastly, if border controls are permanently re-introduced the costs would be much
higher.9
4. Europe at the Crossroads
Given the rich institutional basis of European labor mobility and the evidence of its economic benefits
it is difficult to argue that the last decades have been dominated by a false vision for the future of the
continent. Nevertheless, voters in an evidence-ignoring society have the right to object and to abandon
potential welfare for something else they value. This is the backside of democracy. However, it is
also part of the democratic tradition to fight and argue for evidence-based policy-making and for an
open society by pointing at the huge costs such ignorance would cause. The EU in its current form
and ambition could perfectly survive or collapse even if it solves its migration challenge. But it will
most likely collapse, if it fails to solve the mobility issue.
Hence, there are two base scenarios.10 The first scenario is the “my country first” approach.
This is the current path for the UK under Brexit and for the U.S. under President Trump. Other
countries in the EU are on this way, or may be after the upcoming elections. This is equivalent to the
isolationist view of “fencing ourselves in” pretending we keep others out. The second scenario is
more complex. It is the political and economic union, “a kind of United States of Europe”, in the
vision of Winston Churchill and Robert Schuman, equipped with mechanisms to balance the interests
between the member-states. Such a Europe will be able to withstand the current rocky road and deal
with migration properly, providing flexibility and security to its peoples.
What are the potential strategies for solving the mobility issues? Europe needs answers and
action for internal labor mobility, long-term labor immigration and the refugee challenge. It currently
assumes that each country can deal with the migration issues in its national interests alone, and Europe

A recent paper by the European Commission (2017) discusses 5 scenarios assuming the continuation of the union.

11
could even restrict internal cross-country labor mobility without substantial economic consequences.
But those migration restrictions are labor market constraints, which may negatively affect all
economies in a chain reaction. This is in particular true for the countries in the Eurozone. Hindering
labor mobility there may cause additional problems with the Euro, while improving internal
adjustments through the labor markets could reduce problems with the single currency. Hence, free
labor mobility is a pre-condition for a well-functioning European economy.
To enhance intra-EU labor mobility among EU-nationals the following steps can help:
offering language courses (currently only available to third-country nationals) can alleviate language
barriers; harmonizing the recognition of professional qualifications and instituting something like the
European Professional Card for health professionals would be a useful tool; aligning pension rights
would be a welcoming step.
As a factor of production, labor cannot be viewed and judged in isolation. Labor mobility goes
together with the free mobility of goods and services. The service sector in the EU is still regulated
impeding some professionals from offering their services in some EU-States. Such are the accounting,
legal, telecommunications and construction sectors which are regulated in some countries.
Further, short-term and long-term labor migration with non-EU countries needs a common
basis.11 Points systems could provide transparency for migrants and the host countries and have been
shown to be effective to screen and guide mobility; this can also lead to or imply permanent residency.
The criteria may explicitly include integration indicators such as education, language proficiency, job
characteristics and social activities. An even better, but more controversial, approach for short-term
mobility is to use the labor market as a filter for migration. Those who have a job offer can come and
stay, as long as the work relationship persists. Those who can no longer find a job have to leave, at
least after a transition period, if they do not obtain a permanent residence permit. Circular migration
11
See for the rest of this section also Zimmermann (2016) for a more intensive discussion of the issues in particular in
the context of refugee migration. As has been shown early by Constant and Zimmermann (2005), the entry channel upon
immigration may be crucial for the forthcoming economic performance.
12
contracts between countries may ease such relationships, which are very useful to meet demands for
flexibility in host countries. Offering successful foreign students who graduate the option of staying
if they find a job after some transition period is the most effective long-term immigration policy to
keep high-skilled workers. Lastly, the Blue Card scheme should be modernized and become more
attractive to international migrants by simplifying procedures.
It should be obvious that the refugee burden needs to be fairly shared within a workable EU,
because membership in a union involves both rights and obligations. This implies solutions for the
reception of asylum seekers as well as the labor market integration of refugees taking into account
their skills. Current labor market regulations on asylum seekers and refugees are partly responsible
for their weak performance in the labor market. For instance, a refugee or asylum seeker could better
receive the right to move to the employment channel in a points-based admission system as soon as
she/he gets a decent job offer. Those could be allowed to work as quickly as possible and not be
restricted to a particular region within the country, or after recognition as a refugee even in their initial
host EU-State. This would improve their long-term labor market attachment and their financial
contribution to the public coffers.
5. Conclusions
Current public debates in Europe suggest that the long-term political consensus that migration is
beneficial is broken or at least it is in substantial challenge. Still shared largely by the elites, it gets
declining support in elections. This correlates with a rising disinterest in evidence-based policy
making and in looking at hard facts. However, the free movement of citizens has been an essential
part of the European dream of a better and more equal society of diverse people. Restricting labor
mobility would come in the long-run at large economic and social costs. This would become
eventually transparent to voters, who then may reconsider. Hence, the answer to the crisis of Europe
13
must be “more, not less Europe” by re-installing the vision and creating more efficient and flexible
structures dealing with it. European brains and hearts should work again in parallel.
