Estimating the effects of fiscal policy under the budget constraint

Abstract

I reconsider the short-term effects of fiscal policy when both government spending and taxes are allowed to respond to the level of public debt. I embed the long-term government budget constraint in a VAR, and apply this common trends model to US quarterly data. The main finding is that fiscal consolidation has expansionary effects on output and inflation. Non-Keynesian effects also dominate when debt expands. The expectation of policy adjustments to guarantee fiscal sustainability by future tax rises or spending cuts contracts output today.Fiscal policy, sustainability, spending, taxes, common trends, SVAR
