Economic policy uncertainty and stock market volatility

Abstract

This paper investigates the predictability of economic policy uncertainty (EPU) to stock market volatility. Our in-sample evidence suggests that higher EPU leads to significant increases in market volatility. Out-of-sample findings show that incorporating EPU as an additional predictive variable into the existing volatility prediction models significantly improves forecasting ability of these models. The improvement is robust to the model specifications.
