Policy Uncertainty and the Demand for Money in Korea: An Asymmetry Analysis

Previous studies included money supply volatility as well as output volatility as measures of uncertainty in estimating the demand for money. However, a more comprehensive measure of uncertainty is now constructed for many countries and is known as policy uncertainty. When we included this new measure in the formulation of the demand for money in Korea and relied upon a nonlinear specification of the money demand which allows us to assess the asymmetric effects of changes in the policy uncertainty measure, we found asymmetric long-run effects of policy uncertainty on the demand for cash in Korea. Our conjecture is that increased uncertainty induces Koreans to hold less cash in favor of safer assets and decreased uncertainty has opposite effects, though at different rate.
