We test whether the effect of English proficiency differs between Hispanic and non-Hispanic immigrants. Using 2000 U.S. Census microdata on immigrants who arrived before age 15, we relate labor market, education, marriage, fertility and location of residence variables to their age at arrival in...

Are U.S. immigrants' English proficiency and social outcomes the result of their cultural preferences, or of more fundamental constraints? Using 2000 Census microdata, we relate immigrants' marriage, fertility and residential location variables to their age at arrival in the U.S., and in...

While health affects economic development and wellbeing through a variety of pathways, one commonly suggested mechanism is a "horizon" channel in which increased longevity induces additional education. A recent literature devotes much attention to how much education responds to increasing...

The authors examine portage sites in the U.S. South, Mid-Atlantic, and Midwest, including those on the fall line, a geomorphologic feature in the southeastern U.S. marking the final rapids on rivers before the ocean. Historically, waterborne transport of goods required portage around the falls...

The state of Georgia allocated most of its land to the public through a system of lotteries. These episodes provide unusual opportunities to assess the long-term impact of large shocks to wealth, as winning was uncorrelated with individual characteristics and participation was nearly universal...

Two billion people are infected with intestinal worms. In many areas, the majority of schoolchildren are infected, and the World Health Organization (WHO) has called for school-based mass deworming. The key area for debate is not whether deworming medicine works—in fact, the medical...

We contrast evidence of urban path dependence with efforts to analyze calibrated models of city sizes. Recent evidence of persistent city sizes following the obsolescence of historical advantages suggests that path dependence cannot be understood as the medium-run effect of legacy capital but...
