众所周知，禀赋效应（禀赋效应）是对理性选择的背离，它倾向于认为拥有比不拥有更有价值，并在许多情况下得到了复制。本文探讨了禀赋效应的普遍性、演化意义及其对环境因素的依赖性。我们在坦桑尼亚北部的哈扎布须曼人（Hadza Bushmen）这一孤立的、与进化相关的狩猎采集者群体中，对禀赋效应进行了实验测试。我们发现，生活在偏远地区的哈扎人没有表现出禀赋效应，而生活在现代社会和市场接触程度较高的地理区域的哈扎人则表现出禀赋效应。
The endowment effect, the tendency to value possessions more than non-possessions, is a well-known departure from rational choice and has been replicated in numerous settings. We investigate the universality of the endowment effect, its evolutionary significance, and its dependence on environmental factors. We experimentally test for the endowment effect in an isolated and evolutionarily relevant population of hunter-gatherers, the Hadza Bushmen of Northern Tanzania. We find that Hadza living in isolated regions do not display the endowment effect, while Hadza living in a geographic region with increased exposure to modern society and markets do display the endowment effect.
