Feedback systems are claimed to be a crucial component of the success of electronic marketplaces like eBay or Amazon Marketplace. This article aims to compare the effects of various feedback systems on trust between anonymous traders, through a set of experiments based on the trust game. Our...

We study antisocial preferences in simple money-burning tasks. A decision maker can choose whether or not to reduce another person's payoff at an own cost. We vary across tasks the initial endowment of the decider and the victim. We find that most conventional expectations are refuted: Subjects...

We study the relationship between inequality and inter-groups conflicts (riots), focussing on social inequality. Disadvantaged societal groups experience discrimination and thus have limited access to some social and labour resources like education or employment. First, we experimentally...
