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...

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...

This paper uses census and survey data to identify the wage earning ability and the selectivity of recent Romanian migrants and returnees. We construct measures of selection across skill groups and estimate the average and the skills-specific premium for migration and return for three typical...

This paper revisits the magnet hypothesis and investigates the impact of the welfare generosity on the difference between skilled and unskilled migration rates. The main purpose of the paper is to assess the role of mobility restriction on shaping the effect of the welfare state genrosity. In a...

The wage impact of immigration depends crucially on the elasticity of substitution between similarly skilled immigrants and natives and the elasticity of substitution between high school dropouts and graduates. This paper revisits the estimation of these elasticities. The U.S. data indicate that...
