Abstract
A fundamental implication of asset pricing theory is that investors must earn risk-premiums for bearing exposure to systematic risk. The two-pass cross-sectional regression is a popular approach for risk-premium estimation. The empirical literature has found that this approach often delivers estimates that significantly differ from their time-series counterparts. The paper explores a test of model misspecification that exploits the difference between cross-sectional and time-series risk-premium estimates. The suggested approach complements traditional misspecification tests and may be applied as an alternative to the deployment of misspecification-robust standard errors to test risk-premium significance.
