In this paper we study the impact of immigration to the United States on the vote for the Republican Party by analyzing county-level data on election outcomes between 1990 and 2010. Our main contribution is to separate the effect of high-skilled and low-skilled immigrants, by exploiting the...

Migration networks are usually captured by the number of people from the migrant's country in the host region. Using Mexican migration data, we analyze the effects of the usual network variable and two additional origin-village-specific variables on migrants' location choice.

This paper addresses the question: Why and where do immigrants cluster? We examine the relative importance and interaction of two alternative explanations of immigrant clustering: (1) network externalities and (2) herd behavior. We advance the theory by presenting a framework encompassing both...

Empirical studies in the migration literature have shown that migration enclaves (networks) negatively affect the language proficiency of migrants. These studies, however, ignore the choice of location as a function of language skills. Using data on Mexican migration to the US, we show that...

We investigate whether entrepreneurs in the network of refugees - from the same country of origin - help refugees' labor-market integration by hiring them in their businesses. We analyze the universe of refugee cases without U.S. ties who were resettled in the United States between 2005 and...

The H-1B program allows skilled foreign-born individuals to work in the United States. The annual quota on new H-1B issuances fell from 195,000 to 65,000 for employees of most firms in fiscal year 2004. This cap did not apply to new employees of colleges, universities, and non-profit research...

Many U.S. businessmen are vocally in favor of an increase in the number of H-1B visas. Is there systematic evidence that this would positively affect firms' productivity, sales, employment or profits? To address these questions we assemble a unique dataset that matches all labor condition...

We empirically analyze the impact of immigration to the U.S. on the share of votes to the Republicans and Democrats between 1994 and 2012. Our analysis is based on variation across states and years – using data from the Current Population Survey merged with election data – and addresses the...

Using U.S. county-level data from 1990 to 2010, we study the causal impact of immigration on the provision of local public goods. We uncover substantial heterogeneity across immigrants with different skills, mainly due to the asymmetric impact immigrants have on the per capita tax base and local...
