Recently, efficient approximation algorithms for finding Nash equilibria have been developed for the interesting class of anonymous games, where a player’s utility does not depend on the identity of its opponents. In this paper, we tackle the problem of computing equilibria in such games with continuous player types, extending the framework to encompass settings with imperfect information. In p...

The predictions of classical game theory for one-shot and finitely repeated play of many 2x2 simultaneous games do not correspond to human behavior observed in laboratory experiments. The promising results of learning models in tracking human behavior coupled with the growing electronic market and the number of e-commerce applications has resulted in an increased interest in studying the behavi...

Strategic market games model strategic exchange economies as noncooperative simultaneous moves games. A recent paper by Bloch and Ghosal (J. Econ. Theory, 74 (1997), 368{384.) has shown that strategic market games might exhibit a rather counterintuitive comparative statics property: an increase in the number of traders on the own side of the market might increase the equilibrium utility for any...

OBJECTIVE To evaluate television and simultaneous electronic devices use in adolescents with musculoskeletal pain and musculoskeletal pain syndromes. METHODS A cross-sectional study was performed in 299 healthy adolescents of a private school. All students completed a self-administered questionnaire, including: demographic data, physical activities, musculoskeletal pain symptoms, and use of s...

The ability to accurately assess others’ intents, beliefs, and emotions – called Theory of Mind (ToM) – is conjectured to be important for social cooperation. We study the role of ToM ability in fostering cooperation in the simultaneous and sequential prisoners dilemma (PD) games. Our norm-based model predicts that high ToM ability individuals will believe in more cooperation and cooperate at h...

Building on Genicot and Ray (2006) we develop a model on non-cooperative bargaining that combines the two main approaches in the literature of contracting with externalities: the o¤er game (in which the principal makes simultaneous o¤ers to the agents) and the bidding game (in which the agents make simultaneous o¤ers to the principal). Allowing for agent coordination, we show that the outcome o...

This paper compares the leader and follower payoffs in a duopoly game, as they arise in sequential play, with the Nash payoffs in simultaneous play. If the game is symmetric, has a unique symmetric Nash equilibrium, and players’ payoffs are monotonic in the opponent’s choice along their own best reply function, then the follower payoff is either higher than the leader payoff, or lower than even...

Strategic games model the interaction among simultaneous decisions of agents. The starting point of strategic games is a set of players (agents) having strategies (decisions) and preferences on the game’s outcomes. In this paper we do not assume the decisions and preferences of agents to be given in advance, but we derive them from the agents’ mental attitudes. We specify such agents, define a ...

How can a researcher identify the number of levels of reasoning undertaken by players in a game? We focus on the case where the researcher cannot observe players’ beliefs. Instead, the researcher has access to data which serve as a signal of the players’ strategies. In the case of simultaneous-move games, standard results relate levels of reasoning to rounds of elimination of dominated strategi...

It is well-known that non-cooperative and cooperative game theory may yield different solutions to games. These differences are particularly dramatic in the case of truels, or threeperson duels, in which the players may fire sequentially or simultaneously, and the games may be one-round or n-round. Thus, it is never a Nash equilibrium for all players to hold their fire in any of these games, wh...
