Information Cascades and Revolutionary Regime Transitions
结合两个经典模型，分析信息不对称下民主如何和平出现、革命后出现或寡头制持续，揭示经济因素通过信息级联影响政权更迭的微观基础。
We combine Acemoglu and Robinson's model of the economic origins of democracy with Lohmann's model of political mass protest. This allows us to analyse the economic causes of political regime change based on the microfoundations of revolution. We are able to derive conditions under which democracy arises peacefully, when it occurs only after a revolution and when oligarchy persists. We model these possibilities in a world of asymmetric information, where information cascades are possible, and where these cascades may involve errors in the sense that they make everyone worse off.
