Rural Windfall or a New Resource Curse? Coca, Income, and Civil Conflict in Colombia
研究哥伦比亚古柯价格飙升对农村经济与内战的影响，发现经济收益有限但暴力显著增加，表明冲突由古柯的金融机会驱动，寻租行为限制了经济收益。
We study the consequences of an exogenous upsurge in coca prices and cultivation in Colombia, where most coca leaf is now harvested. This shift generated only modest economic gains in rural areas, primarily in the form of increased self-employment earnings and increased labor supply by teenage boys. The rural areas that saw accelerated coca production subsequently became considerably more violent, while urban areas were affected little. These findings are consistent with the view that the Colombian civil conflict is fueled by the financial opportunities that coca provides and that rent-seeking by combatants limits the economic gains from coca.
