We study credible information transmission by a benevolent Central Bank. We consider two possibilities: direct revelation through an announcement, versus indirect information transmission through monetary policy. These two ways of transmitting information have very different consequences. Since...

We study credible information transmission by a benevolent short-lived central bank. We consider two possibilities: direct revelation through an announcement, versus indirect transmission through monetary policy. We show that, in the presence of externalities creating a wedge between private and...

Emissions trading mechanisms have been proposed, and in some cases implemented, as a tool to reduce pollution. We explore the similarities between emission-trading mechanisms and monetary mechanisms. Both attempt to implement desirable allocations under various frictions, including risk and...

We consider a standard cash in advance monetary model with flexible prices or prices set in advance and show that there are interest rate or money supply rules such that equilibria are unique. The existence of these single instrument rules depends on whether the economy has an infinite horizon...

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

In this paper, we derive principles of optimal cyclical monetary policy in an economy without capital, with a cash-in-advance restriction on household transactions, and with monopolistic firms that set prices one period in advance. The only distortionary policy instruments are the nominal...

Can both short and long-term interest rates be targeted independently? Can the target of the term structure help solve the problem of multiplicity of equilibria that occurs when only the short rate is targeted? Both questions are addressed, and the answer is yes to both.

We show that short and long nominal interest rates are independent monetary policy instruments. The pegging of both helps solving the problem of multiplicity that arises when only short rates are used as the instrument of policy. A peg of the nominal returns on assets of different maturities is...
