We present an axiomatic model of choice involving two agents, motivated by the experimental evidence on non-selfish preferences. We distinguish two classes of social preferences, depending on whether they are or not separable. Altruism and spite (Andreoni & Miller, 2002; Cox et al., 2007) are...

An often-replicated result in the experimental literature on social dilemmas is that a large share of subjects reveal conditionally cooperative preferences. Cooperation generated by this type of preferences is notoriously unstable, as individuals reduce their contributions to the public good in...

This paper addresses the emergence of cooperation in asymmetric pris- oners' dilemmas in which one player chooses after having observed the other player's choice (Trust Game). We use the finite automata approach with complexity costs to study the equilibria of the repeated version of this game....

A single, long-run policeman faces a large population of myopic would- be criminals. This paper shows that this interaction has counterintuitive comparative static properties. A forward-looking inspector might tolerate more law violations than a short-sighted one.

A freeze-out bond exchange offer can occur when a firm wants to replace an exist- ing bond, issued with a covenant, with a new bond that does not have this type of restriction. If the bondholders are not fully coordinated, the shareholders can make the exchange offer unfair to capture wealth...

When contracts are not enforceable, or property rights are not clearly defined, individuals might lack an incentive to carry out costly investments even when they are socially efficient. Some recent contributions such as Ellingsen and Robles (2002) prove that this problem might be less dramatic...
