We extend the notions of evolutionary stability and neutral stability to asymmetric games played between two populations. Assuming that a single strategy is initially played in each population, we consider the simultaneous entry of small proportions of mutants into both populations. The originally played strategy pair is called neutrally stable if the mutants cannot spread. For bimatrix games, ...
We study coordination in dynamic global games with private learning. Players choose whether and when to invest irreversibly in a project whose success depends on its quality and the timing of investment. Players gradually learn about project quality. We identify conditions on temporal incentives under which, in sufficiently long games, players coordinate on investing whenever doing so is not do...
Stochastic games are a general model of interaction between multiple agents. They have recently been the focus of a great deal of research in reinforcement learning as they are both descriptive and have a well-defined Nash equilibrium solution. Most of this recent work, although very general, has only been applied to small games with at most hundreds of states. On the other hand, there are land...
Abstract Background: This study aimed to investigate the effects of addiction to computer games on physical and mental health of students. Methods: The study population includes all students in the second year of public guidance schools in the city of Isfahan in the educational year of 2009-2010. The sample size includes 564 students selected by multiple steps stratified sampling. De...
Background. The cadets experienced particular difficulties in a pandemic period because due to isolation and faced a number of unanticipated challenges like stress, anxiety, and low learning outcomes. Objectives: The aim of the study was to evaluate the effectiveness of sport and traditional games to improve cadets’ learning performance and motivation to learning activities and future service ...
Recently, the study of evolutionary games on networks has attracted great interest, focused mainly on the problem of the emergence of cooperation. A well studied framework for this problem is the Prisoner’s Dilemma game on fixed, evolving or growing networks. In this paper we present a complete picture of the behavior of another important social dilemma, the Stag Hunt game, under an evolutionar...
Experiments that investigate the spontaneous emergence of money in laboratory societies rely on indefinitely repeated helping games with random matching (Camera et al., 2013; Camera and Casari, 2014). An important open issue is lack a general proof existence an equilibrium capable supporting efficient allocation under private monitoring, without money. Here, we fill this gap by offering proof, ...
Hypergraphical games provides a compact model of a network of self-interested agents, each involved in simultaneous subgames with its neighbors. The overall aim is for the agents in the network to reach a Nash Equilibrium, in which no agent has an incentive to change their response, but without revealing all their private information. Asymmetric Distributed constraint satisfaction (ADisCSP) has...
Previous work shows that reputation results may fail in repeated games between two long-run players with equal discount factors. We restrict attention to an infinitely repeated game where two players with equal discount factors play a simultaneous move stage game where actions of player 2 are imperfectly observed. The set of commitment types for player 1 is taken as any (countable) set of finit...
I design an experiment to interpret the observed Lk behavior. It distinguishes between the “Lkb” players, who have high ability and best respond to Lk belief, and the “Lka” players, who could use, at most, k steps of reasoning, and thus could not respond to L(k+1) or higherorder belief. The separation utilizes a combination of simultaneous and sequential ring games. In the sequential games it r...
