Fiscal Spending Multipliers over the Household Leverage Cycle

New paper by Roland Winkler, Mathias Klein and Hamza Polattimur in European Economic Review


This paper investigates household leverage-dependent fiscal policy effects in a two-agent New Keynesian DSGE model with occasionally binding borrowing constraints. Our model successfully replicates empirical evidence showing that fiscal policy’s effectiveness differs significantly across the household leverage cycle. Fiscal multipliers are persistently above unity when government spending rises at the peak of the household leverage cycle. In contrast, increases in government spending at the trough of the household leverage cycle imply fiscal multipliers below unity. We test the model’s predictions on post-WWII U.S. data. www.sciencedirect.comExternal link
