Aspiring for Change: A Theory of Middle Class Activism
构建了一个政权更迭模型，分析中产阶级为何更倾向于参与集体行动推翻现有政权，因为相比穷人，他们对好政府的前景更乐观，并预期他人会持相同看法。
We propose a regime change model in which people are uncertain about both the quality of a specific regime and governance in general. The poor perceive the current regime as bad, rationally infer that all governments are bad, and therefore believe mass movements are futile. The middle class are more sanguine about the prospect of good government, and believe that collective action is effective because they expect many fellow citizens to share the same view. This coordination game with incomplete information does not admit monotone equilibrium but exhibits multiple interval equilibria, where middle class people are more likely to attack the regime.
