This study quantifies the economic effects of two major immigration reforms aimed at legalizing undocumented individuals that entered the United States as children and completed high school: Deferred Action for Childhood Arrivals (DACA) and the DREAM Act. The former offers only temporary legal...

This paper provides a quantitative assessment of the economic contribution of unauthorized workers to the U.S. economy, and the potential gains from legalization. We employ a theoretical framework that allows for multiple industries and a heterogeneous workforce in terms of skills and...

Using a new composite climate-risk index, we show that population in high-risk counties has grown disproportionately over the last few decades, even relative to the corresponding commuting zone. We also find that the agglomeration is largely driven by increases in the (white) working-age...

This paper explores the relationship between economic openness and income per person using cross-country data. To address endogeneity concerns we extend the instrumental-variables strategy first used by Frankel and Romer (1999). First, we show that bilateral geographic characteristics of...

This paper makes two contributions to the literature on the determinants of international migration flows. First, we compile a new dataset on annual bilateral migration flows covering 15 OECD destination countries and 120 sending countries for the period 1980-2006. We also collect data on...

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...

This paper evaluates the welfare impact of observed levels of migration and remittances in both origins and destinations, using a quantitative multi- sector model of the global economy calibrated to aggregate and firm-level data on 60 developed and developing countries. Our framework accounts...

Many empirical studies on the determinants of international migration flows rely exclusively on macro data, and do not account for migrants' self-selection. We analyze a very interesting episode in international migration for which we are able to gather individual-level data covering all...

We estimate empirically the effect of immigration on house prices and residential construction activity in Spain over the period 1998-2008. This decade is characterized by both a spectacular housing market boom and a stunning immigration wave. We exploit the variation in immigration across...
