Fiscal Policy Effectiveness in Japan

Abstract

The effectiveness of fiscal policy in Japan over the past decade has been a matter of great controversy. We investigate the effectiveness of Japanese fiscal policy over the 1976-1999 period using a structural VAR analysis of real GDP, tax revenues, and public expenditures. We find that expansionary fiscal policy, whether in the form of tax cuts or of public works spending, had significant stimulative effects. Using a new method of computing policy multipliers from structural VARs, we calculate that the multiplier on tax cuts is about 25% higher at a four-year horizon than that on public works spending, though both are well in excess of one. A historical decomposition reveals that Japanese fiscal policy was contractionary over much of the 1990s, and a significant proportion of the variation in growth can be attributed to fiscal policy shocks; accordingly, most of the run-up in public debt is attributable to declining tax revenues due to the recession. Examining savings behavior directly, we find limited evidence of Ricardian effects, insufficient to offset the short-term effects of discretionary fiscal policy.
