We study the effects of immigration on native welfare in a general equilibrium model featuring two skill types, search frictions, wage bargaining, and a redistributive welfare state. Our quantitative analysis suggests that, in all 20 countries studied, immigration attenuates the effects of...

This paper shows that different labor market policies can lead to differences in technology across sectors in a model of labor saving technologies. Labor market regulations reduce the skill premium and as a result, if technologies are labor saving, countries with more stringent labor regulation,...

Using longitudinal data on the universe of workers in Denmark during the period 1991-2008 we track the labor market outcomes of low skilled natives in response to an exogenous inflow of low skilled immigrants. We innovate on previous identification strategies by considering immigrants...

A controversial issue in the US is how to reduce the number of illegal immigrants and what effect this would have on the US economy. To answer this question we set up a two-country model with search in labor markets and featuring legal and illegal immigrants among the low skilled. We calibrate...

Scientists, Technology professionals, Engineers, and Mathematicians (STEM workers) are fundamental inputs in scientific innovation and technological adoption, the main drivers of productivity growth in the U.S. In this paper we identify the effect of STEM worker growth on the wages and...

In this paper we analyze whether the gender composition of classmates in high school affects the choice of college-major by shifting it towards those majors preferred by the prevalent gender in the class. We use a novel dataset of 30,000 Italian students graduated from high school between 1985...

In this chapter we analyze immigration and its effect on urban and regional economies focusing on productivity and labor markets. While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that their...

What are the economic consequences to U.S. natives of the growing diversity of American cities? Is their productivity or utility affected by cultural diversity as measured by diversity of countries of birth of U.S. residents? We document in this paper a very robust correlation: US-born citizens...

In this paper we estimate the dynamic relationship between employment in R&D and generation of knowledge as measured by patent applications across OECD countries. In several recently developed models, known as `idea-based' models of growth, the afore mentioned "idea-generating" process is the...

The recent literature on local schooling externalities in the U.S. is rather mixed: positive external effects of average education levels are hardly to be found but, in contrast, positive externalities from the share of college graduates can often be identified. This paper proposes a simple...
