Abstract

In the present research I examine the implications of heterogeneous beliefs about the expected equity premium in a life-cycle portfolio choice model with background income risk. While subjective and dispersed expectations have become a popular mechanism to explain asset pricing phenomena, introducing belief heterogeneity in a standard framework generates an additional puzzle: the sensitivity of risky asset holdings to expected returns is far greater than observed in the data. Incorporating a direct utility component over the safe asset mitigates this excess sensitivity, producing asset allocation responses that are consistent with empirical evidence. The extended model also replicates realistic patterns of stock market participation and conditional risky shares across wealth and age profiles.
