We consider the problem of selecting a subset of a feasible set over which each agent has a strict preference. We propose an invariance property, converse reduction-consistency, which is the converse of reduction-consistency introduced by Yeh (2006), and study its implications. Our results are...

Psychologists report that people make choices on the basis of "decision utilities" that routinely overestimate the "experienced utility" consequences of these choices. This paper argues that this dichotomy between decision and experienced utilities may be the solution to an evolutionary design...

We provide a new interpretation of mixed strategy equilibria that incorporates both von Neumann and Morgenstern's classical concealment role of mixing as well as the more recent Bayesian view originating with Harsanyi. For any two-person game, G, we consider an incomplete information game, IG,...

Why did evolution not give us a utility function that is offspring alone? Why do we care intrinsically about other outcomes, such as food, and what determines the intensity of such preferences? A common view is that such other outcomes enhance fitness and the intensity of our preference for a...

Why did evolution not give us a utility function that is offspring alone? Why do we care intrinsically about other outcomes, food, for example, and what determines the intensity of such preferences? A common view is that such other outcomes enhance fitness and the intensity of our preference for...

The starting point of this paper is a simple, regular, dynamic game in which a subgame-perfect equilibrium fails to exist. Examination of this example shows that existence would be restored if players were allowed to observe the output of a public-randomization device. The main result of the...

We investigate the startling but real possibility that a reduction in calories can lead to a increase in longevity. In perhaps the simplest model, it may be evolutionarily optimal for a permanent reduction in the food supply to cause such an increase in longevity. However, it is impossible to...
