Abstract

We propose a new predictor of real economic activity (REA), namely the representative investor's implied relative risk aversion (IRRA) extracted from S&P 500 option prices. IRRA exploits the forward-looking information in option prices. It increases as risk averse investors enter the market, leading to a decrease in market risk premium thus predicting a REA improvement. In line with our hypothesis, IRRA predicts U.S. REA even when we control for well-known REA predictors. Results hold over both short and long horizons and regardless of the way we conduct inference. Moreover, IRRA forecasts REA out-of-sample over the 2008-2009 great economic recession peak.
