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...

We study with a sample of 1,070 primary school children, aged seven to eleven years,how altruism in a donation experiment is related to children’s risk attitudes and intertemporalchoices. Examining such a relationship is motivated by theories of reciprocalaltruism that provide a cornerstone to...

We study how the distribution of other-regarding preferences develops with age. Based on a set of allocation choices, we classify each of 717 subjects, aged 8–17 years, as either egalitarian, altruistic, or spiteful. We find a strong decrease in spitefulness with increasing age. Egalitarianism...

We investigate how group boundaries, and the economic environment surrounding groups, affect altruistic cooperation and punishment behavior. Our study uses experiments conducted with 525 officers in the Swiss Army, and exploits random assignment to platoons. We find that, without competition...

We study how the distribution of other-regarding preferences develops with age. Based on a set of allocation choices, we can classify each of 717 subjects, aged 8 to 17 years, as either egalitarian, altruistic, or spiteful. Varying the allocation recipient as either an in-group or an out-group...
