Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model we show that the...

Conventional methods for analysing worker flows often focus on gross flows or transition probabilities. This is not necessarily informative for identifying the scale of labour ‘adjustment’ in an economy in the sense of the expansion and decline of industries. We develop a method that relates...

The economic literature has largely overlooked the importance of repeat and circular migration. The paper studies this behaviour by analyzing the number of exits and the total number of years away from the host country using count data models and panel data from Germany. More than 60% of...

We investigate the determinants of the remarkable increase in intra-regional migrations since the 1980’s in Spain, using a large administrative micro dataset on migrants. Conditional migration probabilities are identified by comparing the migrants’ joint distribution of characteristics to...

While the literature has established that there is substantial and highly selective return migration, the growing importance of repeat migration has been largely ignored. Using Markov chain analysis, this Paper provides a modelling framework for repeated moves of migrants between the host and...

There are concerns about the attachment of immigrants to the labor force, and the potential policy responses. This paper uses a bi-national survey on immigrant performance to investigate the sorting of individuals into full-time paid-employment and entrepreneurship and their economic success....

The numbers of migrants from the accessions countries have clearly increased since the enlargement of the EU in 2004. Following enlargement, the net inflow of EU8 immigrants has become 2.5 times larger than the four-year period before enlargement. Poles constitute the largest immigrant group...

It is widely believed that the integration of European economies will have little impact on labour mobility. This does not mean, however, that European labour markets will be unaffected by the process of economic integration. In this paper we show that with increased competition from closer...

This paper studies the effect of economic integration of two regions on the mobility of skilled and unskilled workers across regions and on the resulting location of industrial activity. In particular, it studies what happens when wages in both regions are set by the unions of the ‘West’ –...

This paper examines the degree of persistence of regional relative unemployment. A theoretical model is built to explain the role of migration, labour-force participation, and real wage flexibility at the regional level, in determining such persistence. The model is used to account for the...
