Risk Aversion and Wealth: Evidence from Person-to-Person Lending PortfoliosDaniel ParavisiniLondon School of Economics & Political Science (LSE); Columbia Business School - Finance and Economics Veronica RappoportLondon School of Economics & Political Science (LSE) Enrichetta RavinaColumbia Business School - Finance and Economics January 14, 2013 Abstract: We estimate risk aversion from investors’ portfolio choices on a person-to-person lending plat- form. 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.
