We estimate tax multipliers in a ""Blanchard-Yaari"" consumption model where Ricardian equivalence is broken because the private sector discounts the future at a faster rate than the real rate of interest. The model fits U.S. data since 1955 extremely well-entailing a discount wedge of around 20...

This paper explores the hypothesis that the propensity to consume out of income is not constant but varies, perhaps in a nonlinear fashion, with fiscal variables. It examines whether there is any empirical evidence to support the hypothesis that households move from non-Ricardian to Ricardian...

Would population aging affect the effectiveness of fiscal stimulus? Despite the renewed focus on population aging, there are few empirical studies on the output effects of fiscal policy in aging economies. Our study fills this gap by analyzing this issue in OECD countries. We find that, as...

This paper uses the IMF''s Global Integrated Monetary and Fiscal Model to compute shortrun multipliers of fiscal stimulus measures and long-run crowding-out effects of higher debt. Multipliers of two-year stimulus range from 0.2 to 2.2 depending on the fiscal instrument, the extent of monetary...

Evans (1991) has demonstrated that Blanchard’s (1985) finite-horizon model obeys approximate Ricardian equivalence. We show that this result is determined largely by an unrealistic assumption that labor income grows monotonically over a consumer’s entire lifetime. Introducing more realistic...

This paper examines the macroeconomic implications of life-cycle and dynastic saving behavior for closed and small, open economies. Using an extended version of Blanchard’s overlapping agents model, the analytical framework nests these two competing views, treating agents as either dynastic...

This paper develops an overlapping agents model with age-specific mortality rates. The analytical framework also nests Blanchard''s (1985) ""perpetual youth"" model as a special, though perhaps not realistic, case. With age specific mortality rates, youth is ""fleeting."" Using standard...
