Evaluating Infrastructure Development
Investment in infrastructure is a key lever for economic growth in developing countries; to this end, World Bank financing for infrastructure is roughly 40% of its total commitments. Knowing the impact of these investments is therefore crucial for policy, but estimating the impact of these investments is difficult: Infrastructure is frequently targeted towards regions where growth is anticipated and coupled with complementary investments. Therefore, separating the impacts of any one investment from others or even from pre-existing growth trends is hard. This explains why development economists are pretty obsessed with finding ways to estimate the causal impact of infrastructure projects, which has led to many creative solutions. One possible option is to use spatial jumps.

Evaluating the contact hypothesis in an authoritarian society: can visits by democratic neighbors increase support for democracy? Guest post by Andreas Stegmann

This is the fifth in this year's series of posts by PhD students on the job market.
How should democratic governments interact with their authoritarian counterparts? The options include initiating a trade war or facilitating access to foreign media. Throughout history, a number of democratic governments have focused on engagement policies, specifically on promoting more interactions between citizens that live in democratic and authoritarian societies. However, the effects of such policies are largely unexplored: It is unclear whether attitudes of individuals living in non-democratic societies change when they meet with individuals that are socialized in democratic societies. Moreover, it is unclear whether these engagement policies strengthen the support for democracy during democratic transitions. These questions are important: a recent theoretical literature in political economy suggests that the degree of support for democracy within a society is critical in determining whether countries transition to democracy or experience autocratic reversals (Besley and Persson, 2018).
Natural Experiment & Empirical Strategy
 In my job market paper, I study a policy that was implemented during the Communist dictatorship in East Germany to address these questions. In 1972, the East German regime agreed to reduce restrictions for private visits, specifically for West Germans travelling to East Germany to visit family and friends.

Justin Wolfers had a nice piece in the Upshot about new work on how growing up in a bad neighborhood has long-term negative consequences for kids. The key point of the new work is that the benefits of moving from bad neighborhoods may be particularly high for kids whose parents won’t voluntarily move, but only move because their public housing is demolished.
