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 intertemporal choices. Examining such a relationship is motivated by … theories of reciprocal altruism that provide a cornerstone to understand human social behavior. We find that higher risk …
