Several models of probabilistic choice under uncertainty allow for deterministic choice if one act state-wise dominates the other. Such models have a natural application in game theory where probabilistic choice corresponds to mixed strategies, deterministic choice — to pure strategies and...

Two related models of oligopolistic price competition with homogeneous products are presented. These models are based on weaker assumptions about consumer behavior compared to a classical Bertrand model. In both models firms do not necessarily face a discontinuous demand at an equilibrium price...

The centipede game is a two-player finite game of perfect information where a unique subgame perfect Nash equilibrium appears to be intuitively unappealing and descriptively inadequate. This paper analyzes behavior in the centipede game when a traditional game-theoretical assumption that players...

Unlike the Nash equilibrium, logit quantal response equilibrium is affected by positive affine transformations of players' von Neumann-Morgenstern utility payoffs. This paper presents a modification of a logit quantal response equilibrium that makes this equilibrium solution concept invariant to...

In imperfectly discriminating contests, the contestants contribute effort to win a prize but the highest contributed effort does not necessarily secure a win. The contest success function (CSF) is the technology that translates an individual's effort into his or her probability of winning. This...

The optimal contest architecture for symmetric imperfectly discriminating contests is shown to be generically the two-stage tournament (rather than the one-stage contest). In the first stage the contestants compete in several parallel divisions for the right to participate in the second stage....

There are at least two reasons why multiple prizes can be optimal in symmetric imperfectly discriminating contests. First, the introduction of multiple prizes reduces the standard deviation of contestants' effort in asymmetric equilibria, when the majority of contestants actively participate in...

Preference reversals occur when different (but formally equivalent) elicitation methods reveal conflicting preferences over two alternatives. This paper shows that when people have fuzzy preferences i.e. when they choose in a probabilistic manner, their observed decisions can generate systematic...
