Pre- and Post-Global Financial Crisis Policy Multipliers#

Abstract: This paper estimates the change in policy multipliers in the U.S. relative to their pre-2008 financial crisis levels. It also estimates the likely impact of the 2020 stimulus packages implemented to address COVID-19. The analysis is based on an augmented Blanchard-Perotti model that allows for the dynamic effects of shocks to the central bank balance sheet, real interest rates and debt levels on economic activity. The results suggest that expenditure multipliers have fallen post-2008, mostly because of higher government debt, implying that the effectiveness of fiscal policy has declined. They also suggest that the impact of quantitative easing is beneficial, but requires sizable interventions to have noticeable effects on real GDP. Because of rising debt stocks, dealing with a crisis is becoming more and more costly despite the current low interest rate environment.
