Research with Keynesian-style models has emphasized the importance of the output gap for policies aimed at controlling inflation while declaring monetary aggregates largely irrelevant. Critics, however, have argued that these models need to be modified to account for observed money growth and...

In this paper, we analyze the relation between interest rate targets and money supply in a (bubble-free) rational expectations equilibrium of a standard cash-in-advance model. We examine lump-sum injections of money aimed to implement interest rate sequences that satisfy interest rate target...

Price-level determination requires co-ordination of monetary and fiscal policy to ensure a unique rational expectations equilibrium (REE). This paper derives a number of implications for simple interest rate rules resulting from various fiscal strategies. We show that fiscal choices under either...

Bernanke's strategies for integrating forward guidance into conventional instrument rules anticipate that effective lower bound (ELB) episodes may become part a regular occurrence and that monetary policy should recognize this likelihood (Bernanke (2017a); Bernanke (2017b)). Bernanke's first...

The Fiscal Theory of the Price Level (FTPL) rejects the fundamental 'Ricardian' proposition, that the government budget constraint must hold identically, that is for all admissible values of the variables entering the budget constraint. Accordingly, if the government is to meet its contractual...

This paper argues that the 'fiscal theory of the price level' (FTPL) is fallacious. The source of the fallacy is an elementary economic misspecification. The FTPL denies a fundamental property of any model of a market economy, that the budget constraint of any agent, private or public, must be...

We consider monetary-policy rules with inflation-rate targets and interest-rate or money-growth instruments using a flexible-price, perfect-foresight model. There is always a locally-unique target equilibrium. There may also be below-target equilibria (BTE) with inflation always below target and...

In this paper, I examine what I call Milton Friedman's Monetary Instability Hypothesis. Drawing on Friedman's work, I argue that there are two main components to this view. The first component is the idea that deviations between the public's demand for money and the supply of money are an...
