Stochastic Replicator Dynamics
研究存在冲击时的复制子动力学，证明即使扰动不消失，被严格占优策略迭代剔除的策略也会在长期被淘汰，并给出一个例子说明其均衡选择性质与文献中其他动力学不同。
This article studies the replicator dynamics in the presence of shocks. I show that under these dynamics, strategies that do not survive the iterated deletion of strictly dominated strategies are eliminated in the long run, even in the presence of nonvanishing perturbations. I also give an example that shows that the stochastic dynamics in this article have equilibrium selection properties that differ from other dynamics in the literature.
