In the United States, eradication of persistent federal deficits has won broad bipartisan support. At the same time, political pressures have mounted to strengthen the Federal Reserve's explicit concern with price stability. Proposals under consideration would require a much narrower focus on the part of Fed policymakers, and could be interpreted as targeting the price level rather than a negli...

A prominent policy issue of the 1970s and one that seems certain to dominate the early 1980s is the appropriate response to a prevailing high rate of inflation. The view that there is a long-run trade-off between inflation and unemployment, widely accepted at the end of the sixties, is now held by only a small minority of economists. It is still widely believed, however, that there is a short-r...

We inspect how inflation target announcements are instrumental in building central bank credibility and shaping the public’s inflation expectations. Investigating the role of announcements in two early adopters of inflation targeting by using a time varying credibility measure, we find that both the accuracy and the frequency of inflation announcements have a positive impact on how much attenti...

We calculate optimal monetary policy rules for several variants of a simple optimizing model of the monetary transmission mechanism with sticky prices and/or wages. We show that robustly optimal rules can be represented by interest-rate feedback rules that generalize the celebrated proposal of Taylor (1993). Optimal rules, however, require that the current interest-rate operating target depend ...

Consider the problem of a government that wants to control its debt-to-GDP (gross domestic product) ratio, while taking into consideration the evolution of the inflation rate of the country. The uncontrolled inflation rate follows an Ornstein-Uhlenbeck dynamics and affects the growth rate of the debt ratio. The level of the latter can be reduced by the government through fiscal interventions. T...

WORK IN PROGRESS We investigate the implications of several key features of mortgage markets for optimal policy for open economy inflation targeters. We show that the existence of fixed mortgage contracts shifts the transmission of monetary policy away from the standard interest rate transmission channel towards direct and indirect exchange rate channels. In addition, contracts that allow for h...

We determine optimal discretionary monetary policy in a New-Keynesian model when nominal interest rates are bounded below by zero. Nominal interest rates should be lowered faster in response to adverse shocks than in the case without bound. Such ‘preemptive easing’ is optimal because expectations of a possibly binding bound in the future amplify the e ects of adverse shocks. Calibrating the mod...

Low-tidal-volume ventilation strategies are clearly beneficial in patients with acute lung injury and acute respiratory distress syndrome, but the optimal level of applied positive end-expiratory pressure (PEEP) is uncertain. In patients with high pleural pressure on conventional ventilator settings, under-inflation may lead to atelectasis, hypoxemia, and exacerbation of lung injury through "at...

This paper uses a New Keynesian framework to study the coordination of fiscal and monetary policies, in response to an inflation shock when the policymaker acts with commitment. We first show that, in the simplest New Keynesian model, fiscal policy plays no part in the optimal policy response, because of the comparative advantage which monetary policy has in the control of inflation. We the...

In a simple dynamic macroeconomic model, it is shown that uncertainty about structural parameters does not necessarily lead to more cautious monetary policy, refining the accepted wisdom concerning the effects of parameter uncertainty on optimal policy. In particular, when there is uncertainty about the persistence of inflation, it may be optimal for the central bank to respond more aggressivel...
