Molecular genetic endowments related to cognition, personality, health, and body shape, established at least half a century prior, predict an individual’s risk aversion, beliefs regarding the distribution of expected equity returns, and equity market participation. We estimate that approximately half of the relation between equity market participation and risk aversion, or beliefs regarding the distribution of expected equity returns, arises from the portion of risk aversion, or beliefs, associated with these genetic endowments. Molecular genetic endowments are also strongly associated with many of the variables (e.g., trust, sociability, wealth) shown to explain heterogeneity in equity market participation.
