The sound of silence in prisoner's dilemma and dictator games
نویسندگان
چکیده
Communication increases contributions to public goods. Our experimental results indicate that communication is not always required. Silent identification suffices to raise solidarity in prisoner's dilemma and dictator games. Increases in solidarity are not only due to expectations of reciprocity. While mutual identification induces individuals to converge to the social norm, the spread of the distribution of choices increases with one-way identification and with communication. As others are no longer faceless entities, one-way identification decreases social distance, inducing interaction-specific solutions. Communication allows more information to be transferred and, therefore, more scope for abandoning the norms. # 1999 Elsevier Science B.V. All rights reserved. JEL classi®cation: A13; C72; C91

Learning to be fair
We study the process of equilibrium selection in games when players have "sophisticated" preferences of the type discussed, among others, by Rabin [16] and Segal and Sobel [17]. To this end, we employ standard noisy version of the best response dynamics. We obtain several results concerning some popular games such as the Prisoner's Dilemma, the Battle of the Sexes and the Dictator Game. For exa...
متن کاملHierarchical Bayesian analysis of outcome- and process-based social preferences and beliefs in Dictator Games and sequential Prisoner's Dilemmas.
In this paper, using a within-subjects design, we estimate the utility weights that subjects attach to the outcome of their interaction partners in four decision situations: (1) binary Dictator Games (DG), second player's role in the sequential Prisoner's Dilemma (PD) after the first player (2) cooperated and (3) defected, and (4) first player's role in the sequential Prisoner's Dilemma game. W...
متن کاملERC A Theory of Equity, Reciprocity and Competition
We demonstrate that a simple model, constructed on the premise that people are motivated by both their pecuniary payoff and their relative payoff standing, explains behavior in a wide variety of laboratory games. Included are games where equity is thought to be a factor, such as ultimatum, two-period alternating offer, and dictator games; games where reciprocity is thought to play a role, such ...
متن کاملEmergence of Super Cooperation of Prisoner’s Dilemma Games on Scale-Free Networks
Recently, the authors proposed a quantum prisoner's dilemma game based on the spatial game of Nowak and May, and showed that the game can be played classically. By using this idea, we proposed three generalized prisoner's dilemma (GPD, for short) games based on the weak Prisoner's dilemma game, the full prisoner's dilemma game and the normalized Prisoner's dilemma game, written by GPDW, GPDF an...
متن کاملEscaping Prisoner's Dilemmas: From Discord to Harmony in the Landscape of 2x2 Games
Changes in payoffs can transform Prisoner's Dilemma and other social dilemmas into harmonious win-win games. Using the Robinson-Goforth topology of 2x2 games, this paper analyzes how payoff swaps turn Prisoner's Dilemma into other games, compares Prisoner's Dilemmas with other families of games, traces paths that affect the difficulty of transforming Prisoner's Dilemma and other social dilemmas...
