We study monetary policy in a New Keynesian model with a variable credit spread and scope for central bank asset purchases to matter. A novel financial and labor market interaction generates an endogenous cost-push channel in the Phillips curve and a credit wedge in the IS curve. The "divine...

This work describes the main characteristics of an inflation targeting regime and derives the optimal solution for interest rates according to an original methodology for two models based on the Phillips and IS curves containing general exogenous variables and a complete loss-function

In a canonical staggered pricing model, monetary discretion leads to multiple private sector equilibria. The basis for multiplicity is a form of policy complementarity. Specifically, prices set in the current period embed expectations about future policy, and actual future policy responds to...

Using an empirical New-Keynesian model with optimal discretionary monetary policy, we estimate key parameters - the central bank's preference parameters; the degree of forward-looking behavior in the determination of inflation and output; and the variances of inflation and output shocks - to...

We discuss the Taylor rule near low inflation and interest rates. Using an additional option like term in the loss function, our approach extends the simple Taylor rule to one with an asymmetric response near very low inflation rates. Once calibrated, this payoff profile gives an exact, and...

The timelessly optimal monetary policy proposed by Woodford (2003) may be dominated by alternative timeless policies. We provide a formal justification for these alternative policies. We demonstrate why discount rates do not matter and establish that optimizing over the unconditional expectation...

A monetary economy comprises a vast array of market-clearing interest rates. Central banks exert a direct influence over only a narrow subset of these rates: the rate at which they supply marginal funds to the commercial banking system. Accordingly, the market interest rates which impinge upon...

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...

This paper assesses the importance of the zero lower bound on nominal interest rates for the interest-rate channel of monetary policy. We simulate several interest-rate setting policy rules with either high or low inflation targets. We determine the extent to which the zero bound prevents real...

This paper studies the performance of monetary policy under alternative fiscal regimes in a dynamic New Keynesian optimizing general equilibrium model with wealth effects. The interactions between fiscal policy and interest rate rules are shown to have relevant implications for the existence of...
