Abstract

We show that human subjects are sensitive to the influence of both the risks associated with investments and the influence of relatedness when deciding whether or not to invest in relatives. However, there were significant differences between subjects, with some preferring to emphasise risk while others preferred to emphasise kinship. Subjects who were better at assessing probabilities were more likely to identify risky investments, while those who were better at handling conjoint probabilities were more likely to take both kinship and risk into account.
