Young highly educated workers developed in the 70 s and 80 s a preference for working in larger cities. As a consequence highly educated young workers in 1990 were over-represented in cities, in spite of the lower wage premium they earned for working in crowded metropolitan areas if compared to...

The diffusion of knowledge in the world generates positive externalities if knowledge flows increase the productivity of R&D. Our work analyzes knowledge diffusion and knowledge externalities in generating innovation and in determining productivity. We first estimate the determinants of...

In an interesting and influential paper Robert Lucas (1993) considering the experience of East Asian small economies, suggests that 'on the job' learning could be the principal engine of their miraculous growth in the last 20 years. In this paper I develop an overlapping generation model where...

Using a comprehensive and newly organized dataset the present article shows that the human capital content of emigrants from Italy significantly increased during the 1990 s . This is even more dramatically the case if we consider emigrating college graduates, whose share relative to total...

Using an originally constructed dataset that follows 30,000 Italian individuals from high school to the labor market, we analyze whether the gender composition of peers in high school affected their choice of college major, their academic performance and their labor market income. We exploit the...

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...

We use data on wages and rents in different U.S. cities to assess the amenity effects on production and consumption of cultural diversity as measured by diversity of countries of birth of city residents. We show that US-born citizens living in metropolitan areas where the share of foreign-born...
