This essay aims to explain the nature of monetary and fiscal policy interactions and how those interactions could inform the fiscal rules that countries choose to follow. It makes two points: (1) monetary policy control of inflation requires appropriate fiscal backing; (2) European fiscal...

Basic economic reasoning tells us that monetary and fiscal policies always interact to jointly determine aggregate demand and the overall level of prices in the economy. This paper interprets Sweden's explicit monetary and fiscal frameworks in light of this reasoning, bringing recent Swedish...

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...

When Roosevelt abandoned the gold standard in April 1933, he converted what had been effectively real government debt into nominal government debt to open the door to unbacked fiscal expansion. We argue that he followed a state-contingent fiscal rule that ran nominal-debt-financed primary...

An asset-pricing perspective on inflation reveals that it depends on current and expected monetary and fiscal policies. There are three ways to carry $1 today into the future: money, bonds, and real assets. That dollar's purchasing power varies inversely with the price level. Expected money...

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...

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 use a rational expectations framework to assess the implications of rising debt in an environment with a "fiscal limit." The fiscal limit is defined as the point where the government no longer has the ability to finance higher debt levels by increasing taxes, so either an adjustment to fiscal...

Changes in fiscal policy typically entail two kinds of lags: the legislative lag--between when legislation is proposed and when it is signed into law--and the implementation lag--from when a new fiscal law is enacted and when it takes effect. These lags imply that substantial time evolves...

This paper presents a macroeconomic model that is both a completely specified dynamic general equilibrium model and a probabilistic model for time series data. We view the model as a potential competitor to existing ISLM-based models that continue to be used for actual policy analysis. Our...
