Interrelated global crises - climate change, pandemics, loss of ecosystem services and biodiversity - pose risks that demand collective solutions. Uncertainty about others' behavior, coupled with the dependence on some to take collective efforts to mitigate risks for all (e.g. conservation of...

This paper focuses on social dilemma games where players may or may not meet the same partner again in the future. In line with the notion that contagion of cooperation is more likely the higher the likelihood of being re-matched with the same partner in the future, both a novel experiment and a...

The opportunity to tell a white lie (i.e., a lie that benefits another person) generates a moral conflict between two opposite moral dictates, one pushing towards telling always the truth and the other pushing towards helping others. Here we study how people resolve this moral conflict. What...

What is the extent and nature of religious prosociality? If religious prosociality exists, is it parochial and extended selectively to co-religionists, or is it generalized regardless of the recipient? Further, is it driven by preferences to help others or by expectations of reciprocity? We...

Recent experimental research has shown that a policy put in place endogenously (i.e., through their votes) can be more effective at inducing cooperation in dilemma situations. This paper shows that a similar result holds when a mild sanction is implemented in a voluntary contribution dilemma....

Many modern organisations collect data on individuals’ personality traits as part of their human resource selection processes. We test experimentally whether revealing information on personality data impacts on pro-social behaviour as measured in a one-shot modified dictator game and a public...

The conflict between pro-self and pro-social behaviour is at the core of many key problems of our time, as, for example, the reduction of air pollution and the redistribution of scarce resources. For the well-being of our societies, it is thus crucial to find mechanisms to promote pro-social...
