Abstract
This study examines the impact of macroeconomic announcements on the risk premium and its sources under time-varying preference. We propose a novel method to decompose risk premium changes into the risk and preference components, which are estimated from option prices immediately before and after the announcement using the Recovery Theorem. The results of the empirical analysis for the United States stock market indicate that (1) the negative (positive) macroeconomic announcement surprise increases (decreases) the risk premium; (2) the risk component mainly drives the increase (decrease) in the risk premium; and (3) the preference component has limited influence on the risk premium.
