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...

We analyse an experimental public goods game in which group members can endogenously determine whether they want to supplement a standard voluntary contribution mechanism with the possibility of rewarding or punishing other group members. We find a large and positive effect of endogenous...

We use randomized program offers and multiple follow-up survey waves to examine the effects of entrepreneurship training on a broad set of outcomes. Training increases short run business ownership and employment, but there is no evidence of broader or longer run effects. We also test whether...

This note argues that a rigorous application of simple game theory may provide unambiguous yet non-trivial theoretical insights about the behaviour of players in simple games. This contrasts with a commonly held view that many predictions in applied game theory are either obvious or...

A central insight of agency theory is that when a principal offers a contract to a privately informed agent, the principal trades off ex post efficiency in the bad state of nature against a larger profit in the good state of nature. We report about an experiment with 508 participants designed to...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...
