Wars and State Capacity
构建了一个简单模型，研究不同类型武装冲突如何影响国家从税收中获取收入的财政能力，发现内战会减少财政能力投资，而外部战争则促进投资，国际数据基本支持这一预测。
The article builds a simple model to investigate how different types of armed conflict shape fiscal capacity: the state's ability to raise revenue from taxes. It starts from the simple observation that external war tends to generate common interests across groups in society, whereas internal, civil war entails deep conflicting interests across groups. Our model predicts that—compared to a society without conflict—civil wars lead to smaller investments in fiscal capacity, whereas prospects of external war generally lead to larger investments. Correlations in international data on conflicts and taxation are, by and large, consistent with these predictions.
