Macroeconomic Announcement Premium by Hengjie Ai, Ravi Bansal & Hongye Guo

Abstract
The paper reviews the evidence on the macroeconomic announcement premium and its implications on equilibrium asset pricing models. Empirically, a large fraction of the equity market risk premium is realized on a small number of trading days with significant macroeconomic announcements. We review the literature that demonstrates that the existence of the macroeconomic announcement premium implies that investors’ preferences must satisfy generalized risk sensitivity. We show how this conclusion generalizes to environments with heterogeneous investors and demonstrate how incorporating generalized risk sensitivity affects economic analysis in dynamic setups with uncertainty.

Abstract
We show that asset prices behave very differently on days when important macroeconomic news is scheduled for announcement. In addition to significantly higher average returns for risky assets on announcement days, return patterns are much easier to reconcile with standard asset pricing theories, both cross-sectionally and over time. On such days, stock market beta is strongly related to average returns. This positive relation holds for individual stocks, for various test portfolios, and even for bonds and currencies, suggesting that beta is after all an important measure of systematic risk. Furthermore, a robust risk–return trade-off exists on announcement days. Expected variance is positively related to future aggregated quarterly announcement day returns, but not to aggregated non-announcement day returns. We explore the implications of our findings in the context of various asset pricing models.
