Background Risk and Small-Stakes Risk Aversion

Speaker: Luciano Pomatto, Caltech
Location: Online Event

Abstract: 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.

Written with Xiaosheng Mu, Philipp Strack, and Omer Tamuz.
