This paper investigates how the size of co-ethnic networks at the time of arrival affect the economic success of immigrants in Germany. Applying panel analysis with a large set of fixed effects and controls, we isolate the association between initial network size and long-run immigrant outcomes....

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,...

The presence of foreign multinational enterprises may benefit local economies. In particular, highly productive foreign-owned firms may promote technological catch-up of local firms. Such channel of spillovers is defined as "Veblen-Geschenkron" effect of Foreign Direct Investments and is...

In this paper I first analyze the wage effects of immigrants on native workers in the US economy and its top immigrant-receiving states and metropolitan areas. Then I quantify the consequences of these wage effects on the poverty rates of native families. The goal is to establish whether the...

I show that a CES production-function-based approach with skill differentiation and integrated national labor markets has predictions for the employment effect of immigrants at the local level. The model predicts that if I look at the employment (rather than wage) response by skill to...

Using the large variation in the inflow of immigrants across US states we analyze the impact of immigration on state employment, average hours worked, physical capital accumulation and, most importantly, total factor productivity and its skill bias. We use the location of a state relative to the...

As of 2004 California employed almost 30% of all foreign born workers in the U.S. and was the state with the largest percentage of immigrants in the labor force. It received a very large number of uneducated immigrants so that two thirds of workers with no schooling degree in California were...

We show that the Roy model has more precise predictions about the self-selection of migrants than previously realized. The same conditions that have been shown to result in positive or negative selection in terms of expected earnings also imply a stochastic dominance relationship between the...

In this paper, we estimate the effect of increasing the share of foreign-born Master graduates on the creation of innovative start-ups in the US. We combine information on international students graduating from Master's programs by university cohort with data on start-ups created in the US...

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...
