This paper evaluates the existence of a resource curse on political regimes using the Synthetic Control Method. Focusing on 12 countries, we compare their democracy level with the weighted democracy level of countries that have not experienced oil shocks and have similar pre‐event characteristics. We find that the exogenous variation in oil endowment does not have the same effect on all countries. In most cases, the event has a negative effect in the long run, but countries with a pre‐existing high level of democracy are not negatively affected.

石油发现对民主的异质影响

本文使用综合控制方法评估了政治体制资源诅咒的存在。我们以12个国家为重点，将其民主水平与未经历过石油冲击并具有类似事前特征的国家的加权民主水平进行了比较。我们发现，石油end赋的外源性变化并没有对所有国家产生相同的影响。在大多数情况下，该事件从长远来看会产生负面影响，但是先前拥有高度民主水平的国家不会受到负面影响。
