We use the strategy method to classify subjects into cooperator types in a large-scale online Public Goods Game and find that free riders spend more time on making their decisions than conditional cooperators and other cooperator types. This result is robust to reversing the framing of the game...

This paper reports an experimental investigation of a trust game using either cash or class credit as incentives to participants. We recruit from two auditorium classes. In one class, each token has cash value; in the other, each token is worth extra-credit points added to the students’ overall...

We examine the effect of single-sex schooling on students’ competitiveness by studying middle school students in Seoul who were randomly assigned to either single-sex or coeducational schools within their school districts. Contrary to popular belief and existing studies, our results suggest...

Entry decisions in market entry games usually depend on the belief about how many others are entering the market, the belief about the own rank in a real effort task, and subjects’ risk preferences. In this paper I am able to replicate these basic results and examine two further dimensions:...

How do people react to a mix of good deeds to a third party and bad deeds against them? A modified ultimatum game shows that previous good deeds make responders substantially more tolerant to unfair proposals.

Arad and Rubinstein (2012a) have designed a novel game to study level-k reasoning experimentally. Just like them, we find that the depth of reasoning is very limited and clearly different from that in equilibrium play. We show that such behavior is even robust to repetitions; hence there is, at...
