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...

We estimate a model in which fiscal and monetary policy behavior arise from the optimizing behavior of distinct policy authorities, with potentially different welfare functions. Optimal time-consistent policy behavior fits U.S. time series at least as well as rules-based behavior. American...

This case study compares the importance of prevailing market factors against that of COVID-19 dynamics and policy responses in explaining the evolution of Eurozone (EZ) sovereign spreads during the first half of 2020. Focusing on daily Eurozone CDS spreads, we adopt a multi-stage econometric...

We outline two divergent exit strategies of the U.S. from the post COVID-19 debt-overhang, and analyze their implications on Emerging Markets and global stability. The first strategy is the U.S. aiming at returning to the 2019, pre-COVID mode of loose fiscal policy and accommodating monetary...

Monetary policy decisions tend to be based on systematic analysis of alternative policy choices and their associated macroeconomic impacts: this is science. Fiscal policy choices, in contrast, spring from unsystematic speculation, grounded more in politics than economics: this is alchemy. In...

We develop a rational expectations framework to study the consequences of alternative means to resolve the "unfunded liabilities'' problem---unsustainable exponential growth in federal Social Security, Medicare, and Medicaid spending with no plan to finance it. Resolution requires specifying a...

Slow moving demographics are aging populations around the world and pushing many countries into an extended period of heightened fiscal stress. In some countries, taxes alone cannot or likely will not fully fund projected pension and health care expenditures. If economic agents place sufficient...

Increases in government spending trigger substitution effects--both inter- and intra-temporal--and a wealth effect. The ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior. Studies that impose active monetary policy and passive fiscal policy...

The paper presents the fiscal theory of the price level in a variety of models, including endowment economies with lump-sum taxes and production economies with proportional income taxes. We offer a microeconomic perspective on the fiscal theory by computing a Slutsky-Hicks decomposition of the...

This paper estimates regime-switching rules for monetary policy and tax policy over the post-war period in the United States and imposes the estimated policy process on a calibrated dynamic stochastic general equilibrium model with nominal rigidities. Decision rules are locally unique and...
