This paper studies the relation between changes in financial investment opportunities and changes in the macroeconomy. States variables, such as the lagged production growth rate, the default premium, the term premium, the short-term interest rate, and the market dividend-price ratio, are shown to be indicators of recent and future economic growth and positively correlated with expected future economic growth. These results offer straightforward interpretations of recent evidence on the forecasts of the market excess return by state variable via their forecasts on the macroeconomy.

The authors examine differences in structural characteristics that lead firms of different sizes to react differently to the same economic news. They find that a small firm portfolio contains a large proportion of marginal firms–firms with low production efficiency and high financial leverage. The authors construct two size-matched indices designed to mimic the return behavior of marginal firms and find that these return indices are important in explaining the time-series return difference between small and large firms. Furthermore, risk exposures to these indices are as powerful as log(size) in explaining average returns of size-ranked portfolios.
