An earlier paper by the author investigated the quantitative implications, for the effectiveness of fiscal and monetary policies, of a model treating the determination of long-term interest rates by explicitly imposing the market clearing equilibrium condition that the quantity of bonds issued...

The prevailing view of the economic consequences of financing government deficits, as reflected in the recent economics literature and in recent public policy debates, reflects serious misunderstandings. Debt-financed deficits need not "crowd out" any private investment, and may even "crowd in"...

The textbook optimal policy response to an increase in government debt is simple--monetary policy should actively target inflation, and fiscal policy should smooth taxes while ensuring debt sustainability. Such policy prescriptions presuppose an ability to commit. Without that ability, the...

This paper takes a step toward providing a general equilibrium framework within which to study the nub of the current fiscal debate around the world: what are the tradeoffs between short-run stabilization and long-run sustainability when the perceived riskiness of government debt depends, in...

Dynamic stochastic general equilibrium models that include policy rules for government spending, lump-sum transfers, and distortionary taxation on labor and capital income and on consumption expenditures are fit to U.S. data under a variety of specifications of fiscal policy rules. We obtain...

This paper contributes to the debate about fiscal multipliers by studying the impacts of government investment in conventional neoclassical growth models. The analysis focuses on two dimensions of fiscal policy that are critical for understanding the effects of government investment:...

Dynamic rational expectations models imply that the real value of debt in the hands of the public must be equal to the expected present-value of surpluses. We impose this equilibrium condition on an identified VAR and characterize the way in which the present-value support of debt varies across...

Single-equation estimates of fiscal reaction functions, which relate primary surpluses to past debt-GDP ratios and control variables, are subject to potentially serious simultaneity bias that can produce misleading inferences about fiscal behavior. Biases arise from failure to model the general...

Every economy faces a "fiscal limit" that delivers the maximum government debt-GDP ratio that can be sustained without appreciable risk of default or higher inflation. But governments in advanced economies issue substantial nominal debt and nominal debt is a commitment to repay in nominal units....

The paper explores the macroeconomic consequences of fiscal consolidations whose timing and composition are uncertain. Drawing on the evidence in Alesina and Ardagna (2010), we emphasize whether or not the fiscal consolidation is driven by tax rises or expenditure cuts. We find that the...
