We study the problem of elicitation of subjective beliefs of an agent when the beliefs are ambiguous (the set of beliefs is a non-singleton set) and the agent's preference exhibits ambiguity aversion; in particular, as represented by alpha-maxmin preferences. We construct a direct revelation...

This paper extends Savage's subjective approach to probability and utility from decision problems under exogenous uncertainty to choice in strategic environments. Interactive uncertainty is modeled both explicitly, using hierarchies of preference relations, the analogue of beliefs hierarchies,...

Human utility embodies a number of seemingly irrational aspects. The leading example in this paper is that utilities often depend on the presence of salient unchosen alternatives. Our focus is to understand <i>why</i> an evolutionary process might optimally lead to such seemingly dysfunctional features...

Morris (1996, 1997) introduced preference-based definitions of knowledge and belief in standard state-space structures. This paper extends this preference-based approach to unawareness structures (Heifetz, Meier, and Schipper, 2006, 2008). By defining unawareness and knowledge in terms of...

Substantial evidence in field, lab and thought experiments in multiple disciplines, shows that decision makers often choose a dominated strategy, which contradicts with current economic theory. To bridge this gap between theory and evidence, first, we propose two alternative axiomatic...

We examine voluntary disclosure when the firm (“sender”) is risk-averse and uncertain about audience preferences. We show that some firms stay silent in equilibrium, in contrast to classic “unravelling” results. Silence reduces the sensitivity of a firm's payoff to audiences'...
