A target for the short-term nominal interest rate does not pin down realized inflation. Neither does it pin down the term premia. Short and long rates are threrefore independent monetary policy instruments. A target of the term structure is equivalent to a peg of the returns on state-contingent...

This paper assesses the relevance of the exchange rate regime for stabilization policy. Using both fiscal and monetary policy, we conclude that the exchange rate regime is irrelevant. This is the case independently of the severity of price rigidities, independently of asymmetries across...

We revisit the issue of multiplicity of equilibria when monetary policy is conducted with either the interest rate or the money supply as the sole instrument of policy. We show that in standard monetary models there are interest rate feedback rules, and also money supply rules, that implement a...

How can a particular allocation and prices be implemented? Under what conditions does a policy deliver a unique competitive equilibrium? How many degrees of freedom there are in the determination of the policy variables, or how many are the instruments of policy? In this paper we analyze a...

What instruments of monetary policy must be used in order to implement a unique equilibrium? This paper revisits the issues addressed by Poole (1970) and Sargent and Wallace (1975) on the multiplicity of equilibria when policy is conducted with either interest rate or money supply rules. We show...

In contrast to previous literature, we show that it is possible to use interest rate rules in standard monetary models to implement equilibria that are globally unique. This is a contribution to a literature that either concentrates on conditions for local determinacy, or criticizes that...
