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...

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...

In this paper we analyze the response of career, employment and wage of native Europeans to immigration. We then ask how individual country's policies affect these responses. We use data on 11 EU countries, over the period 1995-2001. We also use the 1991 distribution of immigrants by nationality...

This paper presents a simple Chamberlinian agglomeration model which, like the canonical core-periphery (CP) model, contains two agglomerative forces. However, in contrast to that model, the present model is analytically solvable. Moreover, the present model exhibits a 'supercritical pitchfork...

How many "American jobs" have U.S.-born workers lost due to immigration and offshoring? Or, alternatively, is it possible that immigration and offshoring, by promoting cost-savings and enhanced efficiency in firms, have spurred the creation of jobs for U.S. natives? We consider a multi-sector...

Recent European Legislation on immigration has revealed a particular paradox on migration policies. On the one hand, the trend of recent legislation points to the increasing closure of frontiers (OECD 1999, 2001,2004), also by using immigration quotas. On the other hand, there is an increase of...
