Combining the methodologies of experimental economics and molecular genetics, we report a genetic association between sex-hormone genes and ultimatum game (UG) behavior in a discovery sample from China and a replication sample from Israel. The androgen receptor gene is found to be associated...

This article identifies the common characterizing property, the comonotonic sure-thing principle, that underlies the rank-dependent direction in non-expected utility. This property restricts Savage's sure-thing principle to comonotonic acts, and is characterized in full generality by means of a...

Empirical studies of voting behavior provide evidence of bandwagon effects. Some voters, believing that a particular candidate will win, vote for this candidate even though they prefer the alternative. This paper provides a non-expected utility explanation of such behavior by positing that...

Building on the Ramsey-de Finetti idea of event exchangeability, we derive a characterization of probabilistic sophistication without requiring any of the various versions of monotonicity, continuity, or comparative likelihood assumptions imposed by Savage (1954), Machina and Schmeidler (1992),...
