Tightening corrections budgets, the lack of a legal right to in-person prison visitation, and the increasing availability of video visitation have led many prison and jail administrators to consider limiting opportunities for in-person visitation. This is concerning given the large literature which argues inmates receiving in-person visits are less likely to recidivate upon release. On the other hand, these studies have not determined whether this relationship is causal or is instead driven by the correlation between receiving visits and having a network of family and friends that can offer support upon release. In this article, I estimate the causal effect of in-person visitation on recidivism using unique, administrative data from the Iowa Department of Corrections. I find that visitation itself, as currently implemented in Iowa, has no impact on recidivism. Instead, my results suggest prison policies that create meaningful support networks available to prisoners upon release may yield significant benefits.

We exploit a highly competitive environment in which elite‐female athletes are exposed to the presence of men, but without being in direct competition with them. Specifically, we use variation in how fast the fastest man runs in the New York City Marathon to identify the potential influence of men on female performance while holding constant female‐runners' marginal incentives to perform. Our results suggest that as the men overtake the female runners, the performance of female runners declines differentially across ability, with the largest declines concentrated among lower ability runners.

In the past decade, pirates from Somalia have carried out thousands of attacks on cargo ships sailing through the Gulf of Aden and the Indian Ocean, causing what others have identified as significant damage to maritime trade. In this paper, we use variations in the spread and intensity of Somali piracy to estimate its effect on the volume of international trade. By comparing trade volume changes along shipping routes located in pirate waters to those that are not, we estimate that Somali piracy reduced bilateral trade passing through the Gulf of Aden by 1.7-1.9 percent per year from 2000 to 2010. In addition, we find larger reductions for trade in bulk commodities, which are generally shipped by sea and are more likely to fall prey to piracy attacks. While our estimates suggest that the trade costs of piracy are much lower than what has been suggested in the existing literature, we find that they remain significant and unevenly distributed, with five countries and the European Union shouldering 70% of the total costs.
