This paper investigates patterns and determinants of temporary labour migration in Armenia, Belarus, Georgia, Moldova and Ukraine after EU enlargement in 2004. Migration incidence, destination choices and migration determinants differ between poorer and better-off countries. Although broadly in...

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in an another one) affect the size and human-capital structure of current migration flows. Our...

This paper reconsiders the (self-)selection of international migrants. In an extended Roy-model we analyse the factors which affect the selection bias of migrants. In particular, we find that migrants need not necessarily be (un-)favourably self-selected if the inequality of earnings is higher...

We examine environmental factors as potential determinants of international migration. We distinguish between unexpected short-run factors, captured by natural disasters, as well as long-run climate change and climate variability. Building on a simple neo-classical model we use a panel dataset...

In simple static models, migration increases with the wage differential between host and home country. In a dynamic framework, and if migrations are temporary, the size of the migrant population in the host country depends also on the migration duration. This paper analyses optimal migration...

If migrants return to their origin countries, two questions arise which are of immediate economic interest for both immigration and emigration country: What determines their optimal migration duration, and what are the activities migrants choose after a return. Little research has been devoted...

Die Geschichte der Menschheit ist eine Geschichte der Wanderung. Die Migrationsbewegungen der Gegenwart bestätigen diese Binsenwahrheit. Migration ist grundsätzlich wohlstandsfördernd. Allerdings haben Herkunfts- und Zielländer unterschiedliche Interessen. Eine internationale Organisation...

The scale of international migration flows depends on moving costs that are, in turn, influenced by host-country policies and by the size of migrant networks at destination. This paper estimates the influence of visa policies and networks upon bilateral migration flows to multiple destinations....
