Abstract:
We estimate risk aversion from investors' portfolio choices on a person-to-person lending platform. Our method obtains a risk aversion parameter from each investment and generates a panel that we use to disentangle the elasticity of risk aversion to wealth from heterogeneity in risk attitudes across investors and changes in beliefs. We find an average income-based Relative Risk Aversion of 2.85, a median of 1.62, and substantial heterogeneity and skewness across investors. Risk aversion increases after a negative housing wealth shock, consistent with Decreasing Relative Risk Aversion. We show that ignoring heterogeneity and changes in beliefs would lead to biased estimates.
