Multifactor consumption based asset pricing models using the US stock market as a reference: Evidence from a panel of developed economies

Abstract

In this paper we extend the time series analysis to the panel framework to test the C-CAPM driven by wealth references for developed countries. Specifically, we focus on a linearised form of the Consumption-based CAPM in a pooled cross section panel model with two-way error components. The empirical ndings of this two-factor model with various specifications all indicate that there is significant unobserved heterogeneity captured by cross-country fixed e¤ects when consumption growth is treated as a common factor, of which the average risk aversion coefficient is 4.285. However, the cross-sectional impact of home consumption growth varies dramatically over the countries, where unobserved heterogeneity of risk aversion can also be addressed by random effects.
