Abstract: This paper investigates the dynamic impacts of uncertainty shocks to oil prices on Chinese real GDP (Gross Domestic Product) and investment. Two measures, sample standard deviation and conditional standard deviation of forecast errors estimated from a GARCH (1,1) model of monthly oil prices, are constructed to characterize uncertainty in oil prices. We find that an increase in volatility of oil prices tends to reduce real GDP and investment, which in turn encourages Chinese government to stabilize the economy via expansionary fiscal and monetary policies. Furthermore, a symmetric result arises when we differentiate impacts of increase and decrease in oil price uncertainties. An increase in volatility of oil prices in the uncertainty-increasing sample suppresses real GDP and investment, while a decrease in volatility of oil prices in the uncertainty-decreasing sample boosts macroeconomy. We ascribe the boosting effect of decreasing uncertainty to the combined factor of falling uncertainty and (concomitant) expansionary monetary and fiscal policies. A cross-section check related to economic geography indicates that uncertainty shocks to oil prices generate a significantly greater negative impact on real GDP and investment in East China, where the economy is more industrialized and depends more heavily on oil.
