Asset Pricing with Distorted Beliefs: Are Equity Returns Too Good To Be True?

We study a Lucas asset pricing model that is standard in all respects representative agent's subjective beliefs about endowment growth are distorted. Using constant-relative-risk-aversion (CRRA) utility a CRRA coefficient below ten that exhibit, on average, excessive pessimism over expansions and excessive optimism over" contractions, our model is able to match the first and second moments of the equity premium and" risk-free rate, as well as the persistence and predictability of excess returns found in the data."

Testing Volatility Restrictions on Intertemporal Marginal Rates of Substitution Implied by Euler Equations and Asset Returns

The Euler equations derived from a broad range of intertemporal asset pricing models, together with the first two unconditional moments of asset returns, imply a lower bound on the volatility of the intertemporal marginal rate of substitution. We develop and implement statistical tests of these lower bound restrictions. We conclude that the availability of relatively short time series of consumption data undermines the ability of tests that use the restrictions implied by the volatility bound to discriminate among different utility functions.

Income Risk and Portfolio Choice: An Empirical Study

This paper investigates the relationship between portfolio choice and labor income risk in the National Longitudinal Survey of Youth 1979 Cohort. Permanent income risk (variability of shocks to income that have permanent effect) significantly reduces the share of risky assets in the household's portfolio, while transitory income risk (variability of shocks with no lasting effect) does not. This result provides strong evidence that households' portfolio choices respond to labor income risks in a manner consistent with economic theory.

Testing Volatility Restrictions on Intertemporal Marginal Rates of Substitution Implied by Euler Equations and Asset Returns.

The Euler equations derived from intertemporal asset pricing models, together with the unconditional moments of asset returns, imply a lower bound on the volatility of the intertemporal marginal rate of substitution. This paper develops and implements statistical tests of these lower bound restrictions. While the availability of short time series of consumption data often undermines the ability of these tests to discriminate among different utility functions, the authors find that the restrictions implied by a number of widely studied financial data sets continue to pose quite a challenge to the current generation of intertemporal asset pricing theories.

Asset Pricing with Distorted Beliefs: Are Equity Returns Too Good to Be True?

We study a Lucas asset-pricing model that is standard in all respects, except that the representative agent's subjective beliefs about endowment growth are distorted. Using constant relative risk-aversion (CRRA) utility, with a CRRA coefficient below 10; fluctuating beliefs that exhibit, on average, excessive pessimism over expansions; and excessive optimism over contractions (both ending more quickly than the data suggest), our model is able to match the first and second moments of the equity premium and risk-free rate, as well as he persistence and predictability of excess returns found in the data.
