In this study, we estimate unadjusted and adjusted gender gap in time preference, risk attitudes, altruism, trust, trustworthiness, cooperation and competitiveness using data on 1088 high-school students from 53 classes. These data, collected by running incentivized experiments in Hungarian...

We report experimental findings on the role of charitable promises in bargaining settings. We vary the enforceability of such promises within variants of ultimatum games where the proposer suggest a split between himself, the responder and a char-itable donation. By reneging on initial pledges,...

What makes people willing to pay costs to help others, and to punish others’ selfishness? Why does the extent of such behaviors vary markedly across cultures? To shed light on these questions, we explore the role of formal institutions in shaping individuals’ prosociality and punishment. In...
