How much does disease depress development in human capital and income around the world? I discuss a range of micro evidence, which finds that health is both human capital itself and an input to producing other forms of human capital. I use a standard model to integrate these results and suggest...

We 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 at these...

Using U.S. Census microdata, the authors show that, on average, workers change occupation and industry less in more densely populated areas. The result is robust to standard demographic controls, as well as to including aggregate measures of human capital and sectoral mix. Analysis of the...

Using plausibly exogenous variation in demand for federal funds created by daily shocks to reserve balances, we identify the supply curve facing a bank borrower in the inter-bank market, and study how access to overnight credit is affected by changes in public and private measures of borrower...

Through designs akin to difference-in-differences, Bleakley (2007) produces evidence that the cam- paign to eradicate hookworm from the American South circa 1910 boosted school enrollment in childhood and income in adulthood. This comment works to replicate and reanalyze that study. Innovations...
