While most countries welcome (and some even subsidise) high-skilled immigrants, there is very limited evidence of their importance for domestic firms. To guide our empirical analysis, we first set up a simple theoretical model to show how foreign experts may impact on the productivity and wages...

This paper tests whether marriage to a native affects the probability that an immigrant is employed. We provide a theoretical background which explains how marriage to a native may positively or negatively affect an immigrant's employment probability. Utilizing the 2000 U.S. Census, we first...

In this paper we propose a model for constructing neighbourhoods based on georeferenced data and administrative data. The 431,233 inhabited hectare cells in Denmark are clustered into 9,404 small and 2,296 large neighbourhoods, inhabited on average in 2004 by 572 and 2,343 persons respectively....

Different U.S. states have been affected by immigration to very different extents in recent years. Immigration increases available workers in a state economy and, because of its composition across education groups, it also increases the relative supply of less educated workers. However,...

In the first part of this paper, we present a stylised model of the labour market impact of immigration. We then discuss mechanisms through which an economy can adjust to immigration: changes in factor prices, output mix and production technology. In the second part, we explain the problems of...

This paper uses data from the New Zealand Census to examine how the supply of recent migrants in particular skill groups affects the geographic mobility of the New Zealand-born and earlier migrants. We identify the impact of recent migration on mobility using the "area-analysis" approach, which...

In this paper we document a strong positive correlation of immigration flows with changes in average wages and average house rents for native residents across U.S. states. Instrumental variables estimates reveal that the correlations are compatible with a causal interpretation from immigration...

This paper examines the impact of migration on educational attainments in rural Mexico. Using historical migration rates by state to instrument for current migration, we find evidence of a significant negative effect of migration on schooling attendance and attainments of 12 to 18 year-old boys...

Recent theoretical and empirical studies have emphasized the fact that the prospect of international migration increases the expected returns to skills in poor countries, linking the possibility of migrating (brain drain) with incentives to higher education (brain gain). If emigration is...

In the past 25 years immigration has re-emerged as a driving force in the size and composition of U.S. cities. This paper describes the effects of immigration on overall population growth and the skill composition of cities, focusing on the connection between immigrant inflows and the relative...
