This paper studies a simple New-Keynesian model of fiscal and monetary policy coordination when the policymaker acts under commitment. With a New Keynesian Phillips curve it is optimal to control inflation only through the use of monetary policy. But, when price-setters use a Steinsson (2003)...

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 surveys the research in the past decade on imperfect information models of aggregate supply and the Phillips curve. This new work has emphasized that information is dispersed and disseminates slowly across a population of agents who strategically interact in their use of information....

Recent cross-country studies on the globalization and output-inflation tradeoff correlation find openness has no significant effect on OECD countries. Those studies assume parameter constancy across countries. In this paper, we argue that this assumption does not hold for major industrialized...

We study optimal price setting by a monopolist in an infinite horizon model with stochastic costs, moderate inflation, and costly price adjustment. For realistic parameters, chosen to replicate observed frequencies of price changes, the model fits numerically several empirical regularities. In...

This paper estimates the NAIRU (standing for the Non-Accelerating Inflation Rate of Unemployment) as a parameter that varies over time. The NAIRU is the unemployment rate that is consistent with a constant rate of inflation. Its value is determined in an econometric model in which the inflation...

This article is related to the large recent literature on Phillips curves in sticky- price equilibrium models. It differs in allowing for the degree of price stickiness to be determined endogenously. A closed-form solution for short-term inflation is derived from the dynamic stochastic general...

Recently, the Bank of Japan outlined a “two perspectives” approach to the conduct of monetary policy that focuses on risks to price stability over different time horizons. Interpreting this as pertaining to different frequency bands, we use band spectrum regression to study the determination...

The present Paper provides an overview of recent developments in the analysis of monetary policy in the presence of nominal rigidities. The Paper emphasizes the existence of several dimensions in which the recent literature provides a new perspective on the linkages among monetary policy,...

This article complements the structural New-Keynesian macro framework with a no-arbitrage affine term structure model. Whereas our methodology is general, we focus on an extended macro-model with unobservable processes for the inflation target and the natural rate of output which are filtered...
