Evolutionary Origins of the Endowment Effect: Evidence from Hunter-Gatherers
研究在坦桑尼亚北部的哈扎狩猎采集者中进行实验，发现与世隔绝的群体不表现禀赋效应，而接触现代社会的群体则表现该效应，表明禀赋效应受环境影响。
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.
