Even allowing for substantial uncertainty regarding projections, current US fiscal policies are almost certainly unsustainable. Therefore, policymakers must decide when and in what ways to change policies. Changing policies sooner rather than later would put debt on a lower trajectory and...

We study cointegrating relationships among fiscal variables and output and use them to introduce a new measure of the government's fiscal position. In the US since World War II, we find that the primary surplus-GDP ratio and the government debt-GDP ratio are nonstationary, which invalidates...

We study the effects of debt-financed fiscal transfers in a general equilibrium, heterogeneous-agent model of the world economy. In the long run, increases in government debt anywhere raise the world interest rate and increase private wealth everywhere. In the short run, a country with a...

We develop a new class of general equilibrium models with partially unfunded debt to propose a fiscal theory of trend inflation. In response to business cycle shocks, the monetary authority controls inflation, and the fiscal authority stabilizes debt. However, the central bank accommodates...

The fall in the U.S. public debt/GDP ratio from 106% in 1946 to 23% in 1974 is often attributed to high rates of economic growth. This paper examines the roles of three other factors: primary budget surpluses, surprise inflation, and pegged interest rates before the Fed-Treasury Accord of 1951....

The fiscal theory states that inflation adjusts so that the real value of government debt equals the present value of real primary surpluses. Monetary policy remains important. The central bank can set an interest rate target, which determines the path of expected inflation, while news about the...

Fiscal support measures in response to the COVID-19 pandemic varied in their targeted beneficiaries. Relying on variability across 10 large economies, we study differences in the inflationary effects of fiscal support measures targeting consumers or businesses. Because conventional measures of...

Most of the focus of recent stabilization policy research and practice has been on monetary rather than fiscal policy. This paper explores how, given the limits on monetary policy, fiscal policy could play a larger role. It explores the use of quasi-automatic stabilizers, i.e. changes in taxes...

We calculate impulse response functions from regime-switching models where the driving variable can respond to the shock. Two methods used to estimate the impulse responses in these models are generalized impulse response functions and local projections. Local projections depend on the observed...

As a result of the BoJ's large-scale asset purchases, the consolidated Japanese government borrows mostly at the floating rate from households and invests in longer-duration risky assets to earn an extra 3% of GDP. We quantify the impact of Japan's low-rate policies on its government and...
