It will be politically difficult to liberalize international migration without protecting host-country workers. Professor Martin Ravallion explores in this work the scope for efficiently managing migration using a competitive market for work permits. Host-county workers would have the option of renting out their citizenship work permit for a period of their choice, while foreigners purchase time-bound work permits. Aggregate labor supply need not rise in the host country. However, total output would rise and workers would see enhanced social protection.
Gangs rule millions worldwide. Professor Chris Blattman studies how gangs govern, why, and whether the state can reclaim dominance. He first interviews dozens of gang leaders and thousands of residents in Medellin, Colombia, documenting this clandestine world. They govern to preserve local monopoly rents, but also because the state is remote. To demonstrate, Professor Blattman first harness exogenous variation in exposure to the state across internal borders. Over the long run, places more distant from police and services increase gang rule.

Dr. Salma Mousa answers this question by randomly assigning Iraqi Christians displaced by the Islamic State of Iraq and Syria (ISIS) to an all-Christian soccer team or to a team mixed with Muslims. She finds that the intervention improved behaviors toward Muslim peers: Christians with Muslim teammates were more likely to vote for a Muslim (not on their team) to receive a sportsmanship award, register for a mixed team next season, and train with Muslims six months after the intervention.
