摘要

我分析了一个社会进化模型，在这个模型中，存在一种非排他性的公共利益，可以减少灾难发生的可能性。我的研究表明，虽然在固定的人口中，生产公共产品的有弹性的类型无法与其他更自私的类型进行正面竞争，但如果灾难减少了人口，它们就能生存下来。

The evolution of resilience

I analyze a social evolutionary model in which there is a non-excludable public good that reduces the chances of catastrophe. I show that while resilient types that produce the public good cannot survive head-to-head competition with other more selfish types in a fixed population, they do if catastrophes reduce population.
