Hayek’s approach to cultural and institutional evolution has been frequently criticized because it is explicitly based on the controversial notion of (cultural) group selection. In this paper this criticism is rejected on the basis of recent works on biological and cultural evolution. The...

Inspection games are 2x2 games in which one playermust decide whether to inspect the other player, who in turnmust decide whether to infringe a norm or a regulation.Inspection games have a single, mixed strategy Nashequilibrium, which has counter-intuitive comparative staticsproperties. This...

When contracts are not enforceable, or property rights are not clearly defined, individuals may 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 may be less dramatic than...

The Nash Demand Game (NDG) has been widely employed to model the emergence of moral norms such as property rights. We criticize this use because it neglects the important role played by incentives. Since in a NDG players are assumed to divide a windfall, there is no way to model the idea that...

We discuss the emergence of cooperation in repeated Trust Mini-Games played by finite automata. Contrary to a previous result obtained by Piccione and Rubinstein (1993), we first prove that this repeated game admits two Nash equilibria, a cooperative and a non-cooperative one. Second, we show...

We study the process of equilibrium selection in games when players have social preferences of the type discussed, among others, by Rabin (1993) and Segal and Sobel (2007). To this end, we employ a standard noisy version of the best response dynamics. We obtain several results concerning some...
