Constant risk aversion means that adding the same constant to all outcomes of two distributions, or multiplaying all their outcomes by the same positive constant, will not change the preformence relation between them. In this paper we prove several representation theorems, where constant risk...

Our major claim is that when people behave strategically,it is wrong to interpret the betting rates they announce as their subjective probabilities of the different events. Instead, these rates should be understood as the prices at which subjects are willing to trade certain goods (simple...

A social policy is a rule which assigns each possible set of endowments an allocation of these endowments among members of society. This paper assumes that individuals have preferences over private consumption and preferences over all possible social policies.

This paper discusses two ways in which decision makers facing sequential choices can make themselves invulnerable to Dutch books.

This paper assumes that in addition to the conventional (selfish) preferences over outcomes, players in a strategic environment have preferences over strategies. In the context of two-player games, it provides conditions under which a player's preferences over strategies can be represented as a...

A key feature of the rank dependent model for decision making under risk is that the weighting of an outcome depends on its relative rank. This theory received numerous axiomatizations, however, all these sets of axioms need to make an explicit reference to the ranking of the outcomes. This...
