Donations, risk attitudes and time preferences: A study on altruism in primary school children

We study in a sample of 1070 primary school children, aged seven to eleven years, how altruism in a donation experiment is related to children's risk attitudes and intertemporal choices. Examining such a relationship is motivated by theories of reciprocal altruism that provide a cornerstone for understanding human social behavior. We find that higher risk tolerance and patience in intertemporal choice increase, in general, the level of donations, albeit the effects are non-linear. We confirm earlier results that altruism increases with age during childhood and that girls are more altruistic than boys. Having older brothers makes subjects less altruistic. (C) 2014 Elsevier B.V.
