We introduce a game in preference form, which consists of a game form and a preference structure, and define preference rationalizability that allows for each player's ex-post preferences over outcomes to depend on opponents' actions. We show that preference rationalizability is invariant to...

Consider an analyst who observes an agent taking a sequence of actions. The analyst ponders whether the sequence of actions observed could have been taken by a rational, Bayesian agent. Although the analyst observes the chosen actions, he does not have direct access to the agent's information...

In his article 'The Case for a Multiple Utility Function' (Economics and Philosophy, 2, 159-83), Etzioni took the view that moral acts are qualitatively different from acts aimed at the satisfaction of desires. He introduced moral preferences and argued that these cannot be traded off against...

Social identities prescribe behaviors for people. We identify the marginal behavioral effect of these norms on discount rates and risk aversion by measuring how laboratory subjects' choices change when an aspect of social identity is made salient. When we make ethnic identity salient to...

This paper develops a decision-theoretic framework to study rational inattention (Sims [1998, 2003]). We provide an axiomatic characterization that relates rationally inattentive behavior to attitudes towards flexibility (Kreps [1979]) and temporal resolution of uncertainty (Kreps and Porteus...

We present a new choice model. An agent is endowed with two sets of orderings: pro-orderings and con-orderings. For each choice set, if an alternative is the top-ranked by a pro-ordering (con-ordering), then this is a pro (con) for choosing that alternative. The alternative with more pros than...
