I had a great time at the Pacific Conference for Development Economics this weekend. Sendhil Mullainathan really stole the show with an amazing keynote on his new book, Scarcity (which looks like essential reading for anyone interested in poverty issues), but there were also a number of fascinating studies on the political economy of conflict and post-conflict recovery.
- Tarek Ghani presented some of his joint work with Michael Callen and Josh Blumenstock on the use of mobile money for salary payments in Afghanistan. Given the amount of violence ongoing in the south of the country, there’s a premium on liquidity in case one has to suddenly flee, and the authors were interested in whether cash or mobile accounts better met this need. They found that respondents who believed that higher rates of violence would occur in the future were less likely to hold a balance on their mobile accounts, preferring cash instead. For all the potential of mobile money, there’s still a lot that implementors don’t understand about why people do (or don’t) decide to adopt it.
- Bilal Siddiqi discussed results from a justice sector intervention in Liberia (joint with Justin Sandefur). They framed the study with the observation that, while most Liberians prefer customary forms of dispute resolution to (expensive, inefficient) state courts, women are actually more likely to go to state courts when they’re suing men. The implicit idea is that customary courts are less likely to rule in their favor. The authors look at the effects of a legal aid program which made it easier for people to access state courts, and found that respondents who participated in the program were happier with their judicial outcomes and had better food security.
- Guy Grossman had an interesting piece on connections between political beliefs and exposure to violence amog Israeli soldiers (joint with Dan Miodownik and Devorah Manekin). Using physical health at the time of recruitment as an instrument for combat exposure, he found that previously liberal soldiers were much more likely to oppose concessions to Palestine after their time in the military. Earlier research on this topic had found that exposure to wartime violence and crime victimization often make people more politically engaged, but doesn’t say much about how it might change their political beliefs, so this is an important line of work.
