Abstract：
In the data, stock market volatility weakly or even negatively predicts short-run equity and variance risk premia, challenging traditional risk-return trade-offs at the heart of leading asset pricing models. I show that a puzzling negative volatility-risk premia relationship concentrates in high-uncertainty states, which occur about 20% of the time. While at other times, the relationship is strongly positive. I develop a micro-founded learning model in which investors underreact to structural breaks in high-volatility periods and overreact to transitory variance shocks in normal times. The model can successfully explain the novel time-varying volatility-risk premia relationship at short and long horizons. The model can further account for many other data features, such as a robust positive correlation between equity and variance risk premium, the leverage effect, and negative observations of equity and variance risk premia at the onsets of recessions or market distresses.
