The basic puzzle about the so-called Fisher effect, in which movements in short-term interest rates primarily reflect fluctuations in expected inflation, is why a strong Fisher effect occurs only for certain periods but not for others. This paper resolves this puzzle by reexamining the...

In this paper we examine how target ranges work in the context of a Barro-Gordon (1983) type model, in which the time-inconsistency problem stems from political pressures from the government. We show that target ranges turn out to be an excellent way to cope with the time-inconsistency problem,...

Why is it that inflation is persistently high in some periods and persistently low in other periods? We argue that lack of commitment in monetary policy may bear a large part of the blame. We show that, in a standard equilibrium model, absence of commitment leads to multiple equilibria, or...

We present a model embodying moderate amounts of nominal rigidities which accounts for the observed inertia in inflation and persistence in output. The key features of our model are those that prevent a sharp rise in marginal costs after an expansionary shock to monetary policy. Of these...

This paper examines what strategies policymakers have used to both reduce and control inflation. It first outlines why a consensus has emerged that inflation needs to be controlled. Then it examines four basic strategies: exchange rate pegging, monetary targeting, inflation targeting, and the...

This paper provides new evidence that models of the monetary transmission mechanism should be consistent with at least the following facts. In response to a contractionary monetary policy shock, the aggregate price level responds very little, aggregate output falls, interest rates initially...
