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...

The paper explores the macroeconomic consequences of fiscal consolidations whose timing and composition - either tax- or spending-based - are uncertain. We find that the composition of the fiscal consolidation, its duration, the monetary policy stance, the level of government debt, and...

We develop the theory of price-level determination in a range of models using both ad hoc policy rules and jointly optimal monetary and fiscal policies and discuss empirical issues that arise when trying to identify monetary-fiscal regime. The article concludes with directions in which...

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...

The paper is organized around the following question: when the economy moves from a debtGDP level where the probability of default is nil to a higher level the "fiscal limit" where the default probability is non-negligible, how do the effects of routine monetary operations designed to achieve...
