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...

Whether Europe will be able to stand up to its internal and external challenges crucially depends on its ability to manage its internal mobility and inflows of international migrants. Using a unique expert opinion survey, we document that Europe needs skilled migrants, and skill mismatch is to...

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...

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...

European Union economies are pressed by (i) a demographic change that induces population ageing and a decline of the workforce, and (ii) a split labour market that is characterized by high levels of unemployment for low -skilled people and a simultaneous shortage of skilled workers. This lack of...

The paper studies the demand for foreign university graduates at the firm level. Using a unique dataset on recruitment policies of firms in four European countries, the determinants of demand for internationally mobile highly skilled employees are established. I investigate the number, origin,...

The process of matching between firms and workers is an important mechanism in determining the distribution of wages. In a labor market characterised by large dispersion of workers' productivity and worker-firm complementarity, high quality firms have strong incentives to screen for the quality...
