Macroeconomic Risks and Characteristic-Based Factor Models

We use multivariate GMM models to show that book-to-market, size, and momentum capture cross-sectional variation in exposures to a broad set of macroeconomic factors identified in the prior literature as potentially important for pricing equities. The factors considered include innovations in economic growth expectations, inflation, the aggregate survival probability, the term structure of interest rates, and the exchange rate. Factor mimicking portfolios constructed on the basis of book-to-market, size, and momentum therefore serve as proxy composite macroeconomic risk factors. Conditional and unconditional cross--sectional asset pricing tests indicate that most of the macroeconomic factors are priced. The performance of an asset pricing model based on the macroeconomic factors is comparable to the performance of the Fama and French (1993, 1992) model. However, the momentum factor is found to contain incremental information for asset pricing
