Abstract

Business & Economics Business, Finance Social Sciences
This study examines the impact of changes in economic policy uncertainty (Delta EPU) on the Japanese (excess) stock return. Evidence of a negative Delta EPU coefficient implies that heightened economic policy uncertainty (EPU) will cause a decline in stock returns; however, a positive effect in the lagged coefficient of EPU suggests an increase in stock returns. This phenomenon also displays with a rise in uncertainties for fiscal policy, monetary policy, trade policy, global EPU or total uncertainty in Japanese market. Testing of asymmetrical impacts for an upward or downward shift in uncertainty indicates the presence of inverse relations between uncertainty changes and stock returns. Yet, the degree of asymmetry of uncertainty changes on stock returns is more significant from the Japanese own market as compared with U.S. influence.
