背景风险和小风险规避

Background risk and small-stakes risk aversion

Xiaosheng Mu, Luciano Pomatto, Philipp Strack, Omer Tamuz

摘要:

我们表明,在合理的背景风险水平下,没有风险下的选择理论--如期望效用理论、前景理论或等级相关效用--可以同时满足以下三个经济假设:(1)决策者对小赌博是风险厌恶的,(2)他们尊重随机优势,(3)他们考虑背景风险。

英文摘要:

We show that under plausible levels of background risk, no theory of choice under risk -- such as expected utility theory, prospect theory, or rank dependent utility -- can simultaneously satisfy the following three economic postulates: (i) Decision makers are risk-averse over small gambles, (ii) they respect stochastic dominance, and (iii) they account for background risk.
