We analyze communication about the social returns to investment in a public good. We model two agents who have private information about these returns as well as their own taste for cooperation, or social preferences. Before deciding to contribute or not, each agent submits an unverifiable...

The paper re-examines the idea that a family can be viewed as a community governed by a self-enforcing constitution, and extends existing results in two directions. First, it identifies circumstances in which a constitution is renegotiation-proof. Second, it introduces parental altruism. The...

We analyze the choices between two technologies A and B that both exhibit network effects. We introduce a critical mass game in which coordination on either one of the standards constitutes a Nash equilibrium outcome while coordination on standard B is assumed to be payoff-dominant. We present a...

The mathematical framework of psychological game theory is useful for describing many forms of motivation where preferences depend directly on own or others' beliefs. It allows for incorporating, e.g., emotions, reciprocity, image concerns, and self-esteem in economic analysis. We explain how...

Social dilemmas are among the most puzzling issues in the biological and social sciences. Extensive theoretical efforts have been made in various realms such as economics, biology, mathematics, and even physics to figure out solution mechanisms to the dilemma in recent decades. Although...

We study intra-individual behavioral heterogeneity in an experimental Cournot oligopoly. Previous empirical results in this setting have demonstrated convergence to competitive outcomes, in agreement with theoretical predictions assuming that players imitate successful opponents. We postulate...

Anchoring is one of the most studied and robust behavioral biases, but there is little knowledge about its persistence in strategic settings. This article studies the role of anchoring bias in private-value auctions. We test experimentally two different anchor types. The announcement of a random...

The civil war in Syria has been raging since 2011. We ask whether civil war experience affects voluntary cooperation and its coordination by means of peer punishment. To answer that question, we ran experiments with Syrians and Jordanians, and use a victimization index to measure the individual...

We introduce a reciprocity protocol, an innovative approach to coordinating and sharing rewards in blockchains. Inherently decentralized and easy to implement, it puts emphasis on incentives rather than forcing specific sharing rules from the outset. Analyzing the non-cooperative game the...

Anchoring is a robust behavioral phenomenon modeled predominantly as a bias in individual judgment. We propose a game-theoretic model that considers players' beliefs about others' behavior as a mediator for the effect of the anchor on a player's choice. The results establish that anchoring in...
