In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...

For choice with deterministic consequences, the standard rationality hypothesis is ordinality, i.e., maximization of a … weak preference ordering. For choice under risk (resp. uncertainty), preferences are assumed to be represented by the … objectively (resp. subjectively) expected value of a von Neumann-Morgenstern utility function. For choice under risk, this implies …

This paper studies the evolution of peoplesʼ models of how other people think – their theories of mind. This is formalized within the level-k model, which postulates a hierarchy of types, such that type k plays a k times iterated best response to the uniform distribution. It is found that,...

Harstad and Selten’s article in this forum performs a valuable service by highlighting the dominance of optimization-based models over boundedly rational models in modern microeconomics, and questioning whether optimization-based models are a better way forward than boundedly rational...

This paper highlights a previously unnoticed property of commonly-used discrete choice models, which is that they …

We test the effectiveness of self-help peer groups as a commitment device for precautionary savings, through two randomized field experiments among 2,687 microentrepreneurs in Chile. The first experiment finds that self-help peer groups are a powerful tool to increase savings (the number of...

This paper analyzes the effects of network positions and individual risk attitudes on individuals' strategic decisions in an experiment where actions are strategic substitutes. The game theoretic basis for our experiment is the model of Bramoullé and Kranton (2007). In particular, we are...

This paper experimentally analyzes the effect of network structures on individualsʼ decisions in a game of strategic substitutes. The theoretical basis for our experiment is the model of Bramoullé and Kranton (2007). As predicted, we find that individuals are able to coordinate on equilibria,...
