We show that a so-called expectations-based optimal monetary policy rule has desirable properties in a standard New Keynesian model augmented with a cost channel and inflation rate expectations that are partly backward-looking. In particular, optimal monetary policy under commitment is...

We argue that it is not necessary for the central bank to react to the exchange rate to have a desirable outcome in the economy. Indeed, when the Taylor rule includes contemporane-ous data on the variables in the rule, the central bank can disregard from the exchange rate as long as there is...

We consider standard monetary-policy rules with inflation-rate targets and interest-rate or money-growth instruments using a flexible-price, perfect foresight model. There is always a locally-unique target equilibrium. There are also below-target equilibria (BTE) with inflation always below...
