There is growing evidence that the empirical Phillips curve within the US has changed significantly since the early 1980’s. In particular, inflation persistence has declined sharply. The paper demonstrates that this decline is consistent with a standard Dynamic New Keynesian (DNK) model in...

The authors examine the inflation take-off of the early 1970s in terms of the expectations trap hypothesis, according to which fear of violating the public’s inflation expectations pushed the Fed into producing high inflation. This interpretation is compared with the Phillips curve hypothesis,...

A study of the effect of disinflation policies on monetary velocity, which shows a systematic relation between unexpected changes in the money-income relationship and changes in the trends of inflation rates, and which concludes that the failure to commit to a stable price policy tends to...

What inflation rate should the central bank target? The authors address determinacy issues related to this question in a two-sector model in which prices can differ in equilibrium. They assume that the degree of nominal price stickiness can vary across sectors and that labor is immobile. This...

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

Macroeconomic and microeconomic data paint conflicting pictures of price behavior. Macroeconomic data suggest that inflation is inertial. Microeconomic data indicate that firms change prices frequently. We formulate and estimate a model which resolves this apparent micro - macro conflict. Our...

This paper demonstrates that in a standard monetary model with a cash-in-advance constraint on consumption there exists real indeterminacy whenever the nominal interest rate moves too closely with the real rate. A particular example of such a policy is an inflation rate target. This is not a...

An examination of a standard sticky-price monetary model whose conditions are perturbed relative to the canonical real-business-cycle model by two varying distortions: marginal cost and the nominal rate of interest. The paper explores the implications of two monetary policies that are frequently...

An argument supporting zero inflation as the sole objective of monetary policy, with particular emphasis on the Bank of Canada's commitment to an explicit, low inflation target.

This paper uses a model of a small, open economy to address two monetary policy issues: 1) What restrictions on the policy rule ensure that the central bank does not introduce real indeterminacy into the economy? and 2) What is the optimal long-run rate of inflation? The model's simplicity makes...
