The Political Boundaries of Ethnic Divisions
利用印尼的政策实验，研究重新划分地方行政边界如何影响族群紧张与冲突，发现按族群划界可减少冲突，但若增加族群极化则适得其反，且极化在赢家通吃的选举中更易引发暴力。
We use a policy experiment in Indonesia to show how local political boundaries affect ethnic tension. Redrawing district borders along group lines reduces conflict. However, the gains in stability are undone or even reversed when new boundaries increase ethnic polarization. Greater polarization leads to more violence around majoritarian elections but has little effect around lower-stakes, proportional representation elections. These results point to distinct incentives for violence in winner-take-all settings with contestable public resources. Overall, our findings illustrate the promise and pitfalls of redrawing borders in diverse countries where it is infeasible for each group to have its own administrative unit.
