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...

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....

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...

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...

This Paper studies the effects of mass immigration from the former USSR to Israel in the 1990s on the employment of the native-born. The exogeneity and the size of this inflow make it a ‘natural experiment’ of macroeconomic proportions. An open-economy macroeconomic model is used to analyse...

After unification, real wages in Eastern Germany rose rapidly relative to labour productivity despite high and rising levels of unemployment. This substantial increase in wage levels relative to those in Western Germany is difficult to explain without recourse to models of union behaviour or...

We adopt a general equilibrium approach in order to measure the effects of recent immigration on the Western German labor market, looking at both wage and employment effects. Using the Regional File of the IAB Employment Subsample for the period 1987-2001, we find that the substantial...
