Politicians, the media, and the public express concern that immigrants depress wages by competing with native workers, but 30 years of empirical research provide little supporting evidence to this claim. Most studies for industrialized countries have found no effect on wages, on average, and...

Empirical evidence for the US shows that migrants increase the productivity of regions. To explain the impact of migrants on the average firm productivity we construct a general equilibrium model with monopolistic competition a la Melitz (2003). We consider heterogeneous firms with different...

Economic debate about the consequences of immigration in Germany has largely focused on the wage effects for natives at an aggregate level. Especially the role of imperfect substitutability of migrants and natives gained importance. A new topic is to focus on the firm level by estimating...

Studies regarding the migrants' impact upon performance variables and in particular upon productivity growth - which is the focus of this study - are few although there has been an increased interest in this area. This study addresses this issue in a cross-country and regional perspective with a...

We investigate the relationship between migration and productivity in the UK, using an instrumental variable along the lines suggested by Bianchi, Buonanno and Pinotti (2012). Our results suggest that immigration has a positive and significant impact (in both the statistical sense and more...

Switzerland has experienced a substantial influx of immigrants over the last 50 years after World War II, which has led Switzerland to have among the highest share of foreigners in population among all OECD countries. This paper analyses the migration experience of Switzerland. The analysis...

We develop a job-ladder model with labor reallocation across firms and space, which we design to leverage matched employer-employee data to study differences in wages and labor productivity across regions. We apply our framework to data from Germany: twenty-five years after the reunification,...

Switzerland has experienced a substantial influx of immigrants over the last 50 years after World War II, which has led Switzerland to have among the highest share of foreigners in population among all OECD countries. This paper analyzes the migration experience of Switzerland. The analysis...

The purpose of this paper of this paper is to explore the immigration and productivity in Spain. We estimate the effect of immigration on labor productivity from 2004 until 2008 for Spain. Using firms (SABI) and individuals data (Social Security Records) we calculate the effect by sector and...
