In this paper, we examine the impact of government enforcement of the U.S.-Mexican border on wages in the border regions of the United States and Mexico. The U.S. Border Patrol polices U.S. boundaries, seeking to apprehend any individual attempting to enter the United States illegally. These...

We examine illegal immigration in the United States from Mexico over the period 1976-1995. One challenge is that we do not observe the number of individuals that attempt to enter the United States illegally; we only observe the number of individuals apprehended attempting to cross the...

Empirical evidence on the relationship between democracy and economic reforms is limited to few reforms, countries, and periods. This paper studies the effect of democracy on the adoption of economic reforms using a new dataset on reforms in the financial, capital and banking sectors, product...

Do generations growing up during recessions have different socio-economic beliefs than generations growing up in good times? We study the relationship between recessions and beliefs by matching macroeconomic shocks during early adulthood with self-reported answers from the General Social Survey....

In this paper, we present a model where trade is motivated both by preference for variety and comparative advantages. We use this framework to analyze the welfare implications of trading blocs among countries with different endowments with and without transportation costs. In this framework, we...

We juxtapose the effects of trade and technology on employment in U.S. local labor markets between 1990 and 2007. Labor markets whose initial industry composition exposes them to rising Chinese import competition experience significant falls in employment, particularly in manufacturing and among...

This paper explores the geographic overlap of trade and technology shocks across local labor markets in the United States. Regional exposure to technological change, as measured by specialization in routine task-intensive production and clerical occupations, is largely uncorrelated with regional...

We use data from the NSF Survey of Earned Doctorates to examine the post-degree location choices of foreign-born students receiving PhDs from US universities in science and engineering. Over the period 1960 to 2008, 77% of foreign-born S&E PhDs state that they plan to stay in the United States....

An increasingly influential "technological-discontinuity" paradigm suggests that IT-induced technological changes are rapidly raising productivity while making workers redundant. This paper explores the evidence for this view among the IT-using U.S. manufacturing industries. There is some...
