In this paper we study the existence of the α-core for an n-person game with incomplete information. We follow a Milgrom-Weber-Balder formulation of a game with incomplete information. The players adopt behavioral strategies represented by Young measures. The game unrolls in one step at the ex...

Recently, Askoura et al. (2013) proved the nonemptiness of the α-core of a finite Bayesian game GR with Young measure strategies and nonatomic type spaces, without requiring that the expected payoffs be concave. Under the same hypotheses as theirs, we demonstrate that Scarf’s method (1971)...

We study experimentally a class of pure coordination games as a special case of the Consumer Choice of Prizes game developed by Rapoport et al. (2000). We find a high level of group coordination coupled with considerable switching in the choice of locations. Two models are proposed and tested to...

Empirical studies show that decisions deviate from the predictions of expected utility theory and violate the axiomatic foundations. Hence, many generalizations to non-expected utility theory have been developped. But empirically they did not provide an improvement over the standard approach. In...

We introduce the “relative diffuseness” assumption to characterize the differences between payoff-relevant and strategy-relevant diffuseness of information. Based on this assumption, the existence of pure strategy equilibria in games with incomplete information and general action spaces can...

De Meyer and Moussa Saley explains endogenously the appearance of Brownian Motion in finance by modelling the strategic interaction between two asymmetrically informed market makers with a zero-sum repeated game with One-sided information. In this paper, we generalize this model to a setting of...

This paper presents a neural network based methodology for examining the learning of game-playing rules in never-before seen games. A network is trained to pick Nash equilibria in a set of games and then released to play a larger set of new games. While faultlessly selecting Nash equilibria in...

We examine convergence behavior in simple bimatrix games. We classify possible types of simple games, pick interesting examples of each type, and summarize convergence behavior under various information and player matching protocols.

This paper introduces the concept of firm belief, which is proposed as a new epistemic model for a wide class of preferences. In particular, firm beliefs are shown to have the following desirable properties: (i) they are derived from preferences according to a plausible rule of epistemic...

The paper presents the concept of an "imitation equilibrium" and explores it in the context of some simple oligopoly models. The concept applies to normal form games enriched by a "reference structure" specifying a "reference group" for every player. The reference group is a set of other...
