This paper analyzes the dynamic interaction between norms - internalized restraints on opportunistic behaviour - and institutions - restraints on such behaviour deriving from external enforcement. When individuals following a norm suffer pecuniary losses to doing so, the norm is eroded....

Community enforcement is an important device for sustaining efficiency in some repeated games of cooperation. We investigate cooperation when information about players' reputations spreads to their future partners through links in a social network that connects them. We find that information...

We study impersonal exchange, and ask how agents can behave honestly in anonymous transactions without contracts. We analyze repeated anonymous random matching games, where agents observe only their own transactions. Little is known about cooperation in this setting beyond the prisoner's...

We study environments in which agents are randomly matched to play a Prisoner's Dilemma, and each player observes a few of the partner's past actions against previous opponents. We depart from the existing related literature by allowing a small fraction of the population to be commitment types....

If institutions are essential for long-run performance, why don’t developing countries adopt institutions in developed countries to become rich? In this dynamic model, culture affects a ruler’s institutional choice, while culture itself evolves endogenously. Multiple stable steady states are...

This paper shows that peer pressure may lead to dynamic convergence to a norm that is skewed with respect to preferences in society, yet is endogenously upheld by the population. Moreover, a skewed norm will often be more sustainable than a representative norm. This may explain the skewness of...

This paper agrees that a suitably generalized Darwinism may help understand socioeconomic change, but finds the most publicized generalization by Hodgson and Knudsen unsuitable. To do better, it generalizes the extension of Neo-Darwinism into evolutionary developmental biology (evo-devo), which...
