###  **Today's Speaker**

 Chris Blattman (University of Chicago), "Gang Rule: Understanding and Countering Criminal Governance" ([link to paper](https://osf.io/preprints/socarxiv/5nyqs/))

###  **Abstract**

 Criminal groups govern millions worldwide. Even in strong states, gangs resolve disputes and provide security. Why do these duopolies of coercion emerge? Often, gangs fill vacuums of official power, suggesting that increasing state presence should crowd out criminal governance. We show, however, that state and gang rule are sometimes complements. In particular, gangs could minimize seizures and arrests by keeping neighborhoods orderly and loyal. If true, increasing state presence could increase incentives for gang rule. In Medellín, Colombia, criminal leaders told us they rule to protect drug rents from police. We test gang responses to state presence using a geographic discontinuity. Internal border changes in 1987 assigned blocks to be closer or further from state security for three decades. Gangs exogenously closer to state presence developed more governance over time. They primarily did so in neighborhoods with the greatest potential drug rents. This suggests new strategies for countering criminal governance.

 *Co-sponsored by FAS and IQSS, the Alberto Alesina Seminar on Political Economy supports research-related activities that integrate the study of economics and politics, whether by studying economic behavior in the political process or political behavior in the marketplace. In general, positive political economy is concerned with showing how observed differences among institutions affect political and economic outcomes in various social, economic, and political systems and how the institutions themselves change and develop in response to individual and collective beliefs, preferences, and strategies*.
