We document the return to investing in U.S. nonpublicly traded equity. Entrepreneurial investment is extremely concentrated, yet despite its poor diversification, we find that the returns to private equity are no higher than the returns to public equity. Given the large public equity premium, it is puzzling why households willingly invest substantial amounts in a single privately held firm with a seemingly far worse risk-return trade-off. We briefly discuss how large nonpecuniary benefits, a preference for skewness, or overestimates of the probability of survival could potentially explain investment in private equity despite these findings.

The paper presents empirical evidence based on the US Consumer Expenditure Survey that accounting for limited asset market participation is important for estimating the elasticity of intertemporal substitution (EIS). Differences in estimates of the EIS between assetholders and non-assetholders are large and statistically significant. This is the case whether estimating the EIS based on the Euler equation for stock index returns or the Euler equation for T-bills, in each case distinguishing between assetholders and non-assetholders as best possible. Estimates of the EIS are around 0.3-0.4 for stockholders and around 0.8-1 for bondholders, and are larger for households with larger asset holdings within these two groups.
