In many cases individuals benefit differently from the provision of a public good. We study in a laboratory experiment how heterogeneity in returns and uncertainty affects unconditional and conditional contribution behavior in a linear public goods game. The elicitation of conditional...

Most studies find no collusion in tournaments. This result suggests that social preferences are irrelevant in this context. We investigate the impact of social preferences in a tournament using data from a laboratory experiment with two treatments. In a conentional tournament, an agent receives...

This paper analyzes which type of intrinsic preferences drive an agent’s behavior in a sequential public good game depending on whether the agent is first or second mover. Theoretical predictions are based on heterogeneity of individuals in terms of social and risk preferences. We modelize...

In tournaments, the large variance in effort provision is incompatible with standard economic theory. In our experiment we test theoretical predictions about the role of envy and loss aversion in tournaments. Our results confirm that envy implies higher effort while loss aversion increases the...
