This paper employs stochastic simulations of a small structural rational expectations model to investigate the consequences of the zero bound on nominal interest rates. We find that if the economy is subject to stochastic shocks similar in magnitude to those experienced in the U.S. over the...

This paper attempts at characterising South Korean monetary policy in the period of explicit inflation targeting started in 1999. We explain Korean interest rates in relation to an estimated macro-model, assuming that monetary policy is set optimally. This allows us to obtain the central...

Assigning a discretionary central bank a mandate to stabilize an average inflation rate—rather than a period-by-period inflation rate—increases welfare in a New Keynesian model with an occasionally binding lower bound on nominal interest rates. Under rational expectations, the...

This paper attempts at characterising South Korean monetary policy in the period of explicit inflation targeting started in 1999. We explain Korean interest rates in relation to an estimated macro-model, assuming that monetary policy is set optimally. This allows us to obtain the central bank's...

We identify a novel dimension of monetary policy from high-frequency changes in asset prices around ECB policy events, orthogonal to surprises extracted from risk-free interest rates. We find that it is present in policy events that were interpreted by real-time market commentaries as containing...

In an economy with an occasionally binding zero lower bound (ZLB) constraint, the anticipation of future ZLB episodes creates a trade-off for discretionary central banks between inflation and output stabilization. As a consequence, inflation systematically falls below target even when the policy...

Modifying the objective function of a discretionary central bank to include an interest-rate smoothing objective increases the welfare of an economy where large contractionary shocks occasionally force the central bank to lower the policy rate to its effective lower bound. The central bank with...

We analyse the effectiveness of optimal simple and implementable monetary and fiscal policy rules in stabilising economic activity, inflation and government debt in face of an occasionally binding lower bound on the nominal interest rate in a New Keynesian model. We show that, within the...

This paper assumes that a central bank commits itself to maintaining an inflation target and then asks what measure of the inflation rate the central bank should use if it wants to maximize economic stability. The paper first formalizes this problem and examines its microeconomic foundations. It...

“Forecast targeting,” forward-looking monetary policy that uses central-bank judgment to construct optimal policy projections of the target variables and the instrument rate, may perform substantially better than monetary policy that disregards judgment and follows a given instrument rule....
