Mobility of workers involves flows of labour, human capital and other production factors and thus contributes to a more efficient allocation of resources. Besides these effects on allocative efficiency, migrant flows affect relative wages and also change the international and national...

The 2004 and 2007 enlargements of the European Union were unprecedented in a number of economic and policy aspects. This essay provides a broad and in-depth account of the effects of the post-enlargement migration flows on the receiving as well as sending countries in three broader areas: labour...

This paper estimates the effects of immigration on wages of native workers at the national U.S. level. Following Borjas (2003) we focus on national labor markets for workers of different skills and we enrich his methodology and refine previous estimates. We emphasize that a production function...

This paper explores the influence of the economic cycle on labour mobility within the EU, focusing on the likely impact of the present economic crisis. To do so, we use an econometrically calibrated simulation and a case study of Ireland. We find that, in the short run, the crisis is likely to...

This paper assesses macroeconomic determinants of labour mobility and its role in the adjustment to asymmetric shocks. First, the paper develops stylised facts of mobility at the national and sub-national levels in the EU. Then, it explores the macroeconomic determinants of bilateral migration...

This paper concisely reviews what we know about the experience of an enlarging European Union with free movement of workers within its borders. We focus on the two most recent, Eastern, enlargement waves of 2004 and 2007. We first assess the actual migration flows following the enlargements...

We use data on 11 EU countries, over the period 1995-2001. We also use the 1991 distribution of immigrants by nationality...
