This Paper compares the social efficiency of monetary targeting and inflation targeting when central banks may have private information on shocks to money demand and, because of verifiability problems, the transparency solution is not feasible. Under inflation targeting and monetary targeting,...

This paper addresses two important questions that have, so far, been studied separately in the literature. First, the paper aims at explaining the high volatility of long-term interest rates observed in the data, which is hard to replicate using standard macro models. Building a small-scale...

We provide algorithms to solve a linear-quadratic optimal control problem with commitment. By extending to the case of imperfect information a procedure outlined in Ljungqvist and Sargent (2002), we make the results of Svensson and Woodford (2000) easy to implement. We provide a Mat-lab package...

We determine optimal monetary policy under commitment in a forwardlooking New Keynesian model when nominal interest rates are bounded below by zero. The lower bound represents an occasionally binding constraint that causes the model and optimal policy to be nonlinear. A calibration to the U.S....

This Paper studies an advantage of commitment over discretion when a central bank observes only noisy measures of current inflation and output, in the context of an optimizing model with nominal-price stickiness. Under a commitment regime, if current policy turns out to be too expansionary...

Commitment in monetary policy leads to equilibria that are superior to those from optimal discretionary policies. A number of interest rate reaction functions and instrument rules have been proposed to implement or approximate commitment policy. We assess these optimal reaction functions and...

We review the recent work on interest rate setting, which emphasizes the desirability of designing policy to ensure stability under learning. Appropriately designed expectations-based rules can yield optimal rational expectations equilibria that are both determinate and stable under learning....

We determine optimal monetary policy under commitment in a forwardlooking New Keynesian model when nominal interest rates are bounded below by zero. The lower bound represents an occasionally binding constraint that causes the model and optimal policy to be nonlinear. A calibration to the U.S....

We compute the optimal non-linear interest rate policy under commitment for a forward-looking stochastic model with monopolistic competition and sticky prices when nominal interest rates are bounded below by zero. When the lower bound binds, the optimal policy is to reduce the real rate by...

This paper demonstrates how a target for money growth can be beneficial for an inflation targeting central bank acting under discretion. Because the growth rate of money is closely related to the change in the interest rate and he growth of real output, delegating a money growth target to the...
