文章摘要：

Ambiguity aversion (also known as uncertainty aversion) describes an attitude of preference for known risks over unknown risks. It is demonstrated in the Ellsberg paradox(i.e. that people prefer to bet on an urn with 50 red and 50 blue balls, than in one with 100 total balls but where the number of blue or red balls is unknown). We study this problem with a novel design and show that subjects’ choices violate the predictions of the prominent expected utility theories　 and are consistent with the non-expected utility model CEU.

Time permitting, Dr. Yang will also talk about an experiment on Public Goods Provision with Voting for Exclusion, Exit, and Mergers.
