- The role of neuromodulators in the enforcement of cooperation is still not well understood. Here, we provide evidence that intranasal applied oxytocin, an important hormone for modulating social behavior, enhances the inclination to sanction free-riders in a social dilemma situation. Contrary to the notion of oxytocin being a pro-social hormone, we found that participants treated with oxytocin exhibited an amplification of self-reported negative social emotions such as anger towards free-riders, ultimately resulting in higher magnitude and frequency of punishment of free-riders compared to placebo. Furthermore, we found initial evidence that oxytocin contributes to the positive effects of a punishment institution by rendering cooperation preferable in the oxytocin condition for even the most selfish players when punishment was available. Together, these findings imply that the neural circuits underlying altruistic punishment are partly targeted by the oxytonergic system and highlight the importance of neuromodulators in group cohesion and norm enforcement within social groups.

- Evidence of gender differences in cooperation in social dilemmas is inconclusive. This paper experimentally elicits unconditional contributions, a contribution vector (cooperative preferences), and beliefs about the level of others' contributions in variants of the public goods game. We show that existing inconclusive results can be understood when controlling for beliefs and underlying cooperative preferences. Robustness checks of our original data from Germany, based on data from six countries around the world, confirm our main empirical results: Women are significantly more often classified as conditionally cooperative than men, while men are more likely to be free riders. Beliefs play an important role in shaping unconditional contributions, supporting the view that these are more malleable or sensitive to subtle cues in women than in men. (c) 2020 Elsevier B.V.
