The authors investigate the cross-sectional relation between dividend yield and expected return and attempt to include various effects of changing risk measures and changing risk premiums. A stock's risk is measured by its sensitivities to two factors, a market factor and a changing-risk-premium...

A Bayesian approach is used to investigate a sample's information about a portfolio's degree of inefficiency. With standard diffuse priors, posterior distributions for measures of portfolio inefficiency can concentrate well away from values consistent with efficiency, even when the portfolio is...

This article presents a mean-variance framework for likelihood- ratio tests of asset pricing models. A pricing model is tested by examining the position of one or more reference portfolios in sample mean-standard-deviation space. Included are tests of both single-beta and multiple-beta...

The authors find that conditional means and variances of consumption growth vary through time, and this variation appears to be associated with the business cycle. A pricing model with fluctuating means and variances of consumption growth provides implications about conditional moments of...

We investigate the cross-sectional relation between dividend yield and expected return and attempt to include various effects of changing risk measure and changing risk premiums. A stock’s risk is measured by its sensitivities to two factors, a market factor and a changing-risk-premium factor....
