We refine the understanding of individual preferences across social lotteries, whereby the payoffs of a pair of subjects are exposed to random shocks. We find that aggregate behavior is ex-post and ex-ante inequality averse, but also that there is a wide variety of individual preferences and...

Recent evidence suggests that nudges, i.e. alterations in the decisional context, can have large effects on decisions and can improve individual and public welfare. This paper presents the results of a controlled experiment that was designed to evaluate not only the effectiveness of a default...

We study the coexistence of strategies in the indirect reciprocity game where agents have access to second-order information. We fully characterize the evolutionary stable equilibria and analyze their comparative statics with respect to the cost-benefit ratio (CBR). There are indeed only two...
