We investigate the derivation of optimal interest rate rules in a simple stochastic framework. The monetary authority chooses to minimise an asymmetric loss function, where the monetary authority places positive weight on negative (positive) deviations of output (inflation) and zero weight on...

We propose a new interest rate rule that implements the optimal equilibrium and eliminates all indeterminacy in a canonical New Keynesian model in which the zero lower bound on nominal interest rates (ZLB) is binding. The rule commits to zero nominal interest rates for a length of time that...

I give necessary and sufficient conditions under which interest-rate feedback rules eliminate aggregate instability by inducing a globally unique optimal equilibrium in a canonical New Keynesian economy with a binding zero lower bound. I consider a central bank that initially keeps interest...

The mainstream inflation-targeting literature makes the strong assumption that the central bank can exactly target the interest rate which affects investment and consumption decisions and hence the money supply plays no role in the monetary policy strategy. This assumption is equivalent to...

This note takes part in the debate on the topic “a macroeconomics without LM”. It shows that, when the central bank does not control directly the interest rates on the money and financial markets, LM curve has another role to play than to determine in an endogenous way the money supply when...

The paper analyzes the experience with unconventional measures to cope with the Zero Lower Bound. It argues that forward guidance and quantitative easing are the natural extension of optimal monetary policy within the New Keynesian Framework, facing a Lower Bound. Unconventional policy had...

In a model with forward-looking expectations, the paper examines communication of central bank forecasts when the inflation target is subject to unobserved changes. It characterizes the effect of disclosure of forecasts on inflation and output stabilization and the choice of an active versus...
