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...

The 2004 accession of Eastern European countries (EU8) to the European Union has generated concerns about the influx of low-skill immigrants to the Western member states (EU15). Only three countries, namely Ireland, Sweden, and the UK, did not impose restrictions to immigration from Eastern...

Programs aimed at reducing the presence of unauthorised immigrants are often at the core of the migration policy debate in host countries. In recent years, a growing body of empirical literature has attempted to understand the effect of lacking legal status on immigrants' outcomes and behaviour....

Fluency in (or ease to quickly learn) the language of the destination country plays a key role in the transfer of human capital from the source country to another country and boosts the immigrant's rate of success at the destination's labor market. This suggests that the ability to learn and...

Recent empirical evidence seems to show that temporary migration is a widespread phenomenon, especially among highly skilled workers who return to their countries of origin when these begin to grow. This paper develops a simple, tractable overlapping generations model that provides a rationale...

In deliberating whether to pursue an undergraduate education in the US, a foreign student takes into consideration the expected probability of securing US employment after graduation. The H-1B visa provides a primary means of legal employment for collegeeducated foreign-nationals. In October...

Are U.S. immigrants' English proficiency and social outcomes the result of their cultural preferences, or of more fundamental constraints? Using 2000 Census microdata, we relate immigrants' marriage, fertility and residential location variables to their age at arrival in the U.S., and in...

In this paper, we investigate how changes in the skill mix of local labor supply are absorbed by the economy. We distinguish between three adjustment mechanisms: through factor prices, through an expansion in the size of those production units that use the more abundant skill group more...
