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...

Could policy changes boost economic growth enough and at a low enough cost to meaningfully reduce federal budget deficits? We assess seven areas of economic policy: immigration of high-skilled workers, housing regulation, safety net programs, regulation of electricity transmission, government...

The Global Financial Crisis and the COVID-19 pandemic were two major shocks to the world economy in the 21st century. In this study, we analyze the patterns of recessions and recoveries of 101 advanced and developing economies. We identify the turning points of recessions and expansions between...

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...

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...

We build a tractable New Keynesian model to jointly study four types of monetary and fiscal policy. We find quantitative easing (QE), lump-sum fiscal transfers, and government spending have the same effects on the aggregate economy when fiscal policy is fully tax financed. Compared with these...

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...

This paper revisits the relationship between federal debt and interest rates, which is a key input for assessments of fiscal sustainability. Estimating this relationship is challenging due to confounding effects from business cycle dynamics and changes in monetary policy. A common approach is to...

We conduct a systematic analysis of the costs and benefits of large-scale securities purchases, using the Federal Reserve's QE4 program as a concrete example. This program was initiated at the onset of the pandemic in March 2020 and continued for two years, leading to a doubling of the Fed's...

We develop a unified framework for optimally managing public portfolios for a class of macro-finance models that include widely-used specifications for households' risk and liquidity preferences, market structures for financial assets, and trading frictions. An optimal portfolio hedges...
