摘要翻译:
在持续收益异质性存在的情况下,在许多演化动态下,总体策略的演化在很大程度上依赖于潜在的策略组合,而在标准BRD下的总体动态退化为均质光滑BRD,其中持续收益异质性平均为均质短暂收益冲击。在本文中,我们考虑了异质种群中的确定性进化动力学,并通过对持久收益异质种群的鲁棒性,发展了更强的局部稳定性概念。众所周知,如果在给定的演化动态中,切换速率与切换的收益相关,则非聚集性一般成立。为了参数化一个演化动态的收益敏感性,我们提出使用有界支持切换成本的回火最佳响应动态。

英文摘要:
In the presence of persistent payoff heterogeneity, the evolution of the aggregate strategy hugely depends on the underlying strategy composition under many evolutionary dynamics, while the aggregate dynamic under the standard BRD reduces to a homogenized smooth BRD, where persistent payoff heterogeneity averages to homogeneous transitory payoff shocks. In this paper, we consider deterministic evolutionary dynamics in heterogeneous population and develop the stronger concept of local stability by imposing robustness to persistent payoff heterogeneity. It is known that nonaggregability holds generically if the switching rate in a given evolutionary dynamic correlates with the payoff gain from a switch. To parameterize the payoff sensitivity of an evolutionary dynamic, we propose to use tempered best response dynamics with bounded support of switching costs.
