In nash equilibrium, agents are autarchic in their optimization protocol, whereas in Kantian equilibrium,they optimize in an interdependent way. Typically, researchers into the evolution of homo economicus treat preferences as being determined by selective adaptation, but hold fixed the...

n this paper we propose a pluralistic and multi-dimensional ap- proach to cooperation. Specifically, we seek to show that, in certain settings, less unconditional forms of cooperation may be combined with more gratuitous ones. Starting with the prisoner’s dilemma game, the evolution of...

We study a dynamic process where agents in a network interact in a Prisoner’s Dilemma. The network not only mediates interactions, but also information: agents learn from their own experience and that of their neighbors in the network about the past behavior of others. Each agent can only...

During the last three decades the ascent of behavioral economics clearly helped to bring down artificial disciplinary boundaries between psychology and economics. Noting that behavioral economics seems still under the spell of the rational choice tradition - and, indirectly, of behaviorism - we...

We present a dynamic model of club formation in a society of identical people. Coalitions consisting of members of the same club can form for one period and coalition members can jointly deviate. The dynamic process is described by a Markov chain defined by myopic optimization on the part of...

Saez-Marti and Weibull [4] investigate the consequences of letting some agents play a myopic best reply to the myopic best reply in Young's [8] bargaining model. This is how they introduce ''cleverness'' of players. We analyze such clever agents in general finite two-player games. We show that...

The paper discusses community enforcement in infinitely repeated, two-action games with local interaction and uncertain monitoring. Each player interacts with and observes only a fixed set of opponents, of whom he is privately informed. The main result shows that when beliefs about the...

This paper studies a repeated play of a family of games by resource-constrained players. To economize on reasoning resources, the family of games is partitioned into subsets of games which players do not distinguish. An example is constructed to show that when games are played a finite number of...

It is common in organizational life to be simultaneously involved in multiple collective actions. These collective actions may be modeled using public good dilemmas. The developing social dilemma literature has two perspectives – the “divided loyalties” and “conditional cooperation”...

Consider a situation where players in a prisoner's dilemma game can approve or reject the other's choice such as cooperation or defection. If both players approve the other's choice, the outcome is the one they chose, whereas if either one rejects the other's choice, the outcome is the one when...
