It Takes Two: An Explanation for the Democratic Peace
解释民主和平假说，即民主国家之间很少开战。模型显示，在信息不对称和战略互补下，两个民主国家间的互动不同于其他组合，和平解决冲突的概率最高，但和平需要双方都是民主国家。
In this Paper, we provide an explanation of the democratic peace hypothesis, i.e., the observation that democracies rarely fight one another. We show that in the presence of information asymmetries and strategic complements, the strategic interaction between two democracies differs from any other dyad. In our model, two democracies induce the highest probability of peaceful resolution of conflicts. But it takes two for peace; one democracy involved in a conflict does not necessarily increase the probability of a peaceful resolution compared to a conflict between two non-democratic regimes.
