The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al. (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

This Paper takes a new look at the long-run dynamics of inflation and unemployment in response to permanent changes in the growth rate of the money supply. We examine the Phillips curve from the perspective of what we call ‘frictional growth’, i.e. the interaction between money growth and...

This paper integrate microfoundations of wage staggering into a simple dynamic general equilibrium model with rational expectations. In this context we show that a permanent increase in money growth leads to a permanent increase in the rate of inflation and a permanent reduction in the level of...

In this Paper we analyse how monetary policies will be affected in a cashless society. Our main conclusions are that the central bank will lose its traditional instruments of monetary policy. Open market operations and advances to banks will become ineffective as instruments to control the...

In monetary policy strategies geared towards maintaining price stability, conditional and unconditional forecasts of inflation and output play an important role. In this Paper we illustrate how modern sticky-price dynamic stochastic general equilibrium (DSGE) models, estimated using Bayesian...

This paper explores the influence of wage and price staggering on monetary persistence. We show that, for plausible parameter values, wage and price staggering are highly complementary in generating monetary persistence. We do so by proposing the new measure "quantitative persistence," after...

We develop a theory that rationalizes the use of a dominant unit of account in an economy. Agents enter into non-contingent contracts with a variety of business partners. Trade unfolds sequentially in credit chains and is subject to random matching. By using a dominant unit of account, agents...

This paper studies monetary policy in models where multiple assets have different liquidity properties: safe and "pseudo-safe" assets coexist. A shock worsening the liquidity properties of the pseudo-safe assets raises interest-rate spreads and can cause a deep recession cum deflation. Expanding...

We study the interplay between competition and trust as efficiency-enhancing mechanims in the private provision of money. With commitment, trust is automatically achieved and competition ensures efficiency. Without commitment, competition plays no role. Trust does play a role but requires a...

Cross-country evidence on inflation and inequality suggests that they are positively correlated. I explore the hypothesis that this correlation is the outcome of a distributional conflict underlying the determination of fiscal policy.
