Pricing Model Performance and the Two-Pass Cross-Sectional Regression Methodology

Deskripsi

Over the years, many asset pricing studies have employed the sample cross-sectional regression (CSR) R2 as a measure of model performance. We derive the asymptotic distribution of this statistic and develop associated model comparison tests, taking into account the inevitable impact of model misspecification on the variability of the two-pass CSR estimates. We encounter several examples of large R2 differences that are not statistically significant. A version of the intertemporal CAPM exhibits the best overall performance, followed by the "three-factor model" of Fama and French (1993). Interestingly, the performance of prominent consumption CAPMs proves to be sensitive to variations in experimental design..Printed Journal
