Abstract

This paper examines the contribution of Economic Policy Uncertainty (EPU) to the persistence of shocks to stock market volatility. The study applies an innovative approach that compares the half-life of a shock in the context of a bivariate V AR model that includes the volatility of stock returns and EPU, with the half-life of the equivalent univariate ARMA model for the stock return volatility. Based on daily data for the UK and the US, the empirical results corroborate that EPU contributes to the persistence of shocks to stock market volatility for both countries. This contribution is higher for the US, where 14.3% of the persistence of shocks to stock market volatility can be attributed to the EPU index.
