The celebrated Taylor rule provides a simple formula that aims to capture how the central bank interest rate is adjusted as a linear function of inflation and output gap. However, the rule does not take explicitly into account the zero lower bound on the interest rate. Prior studies on interest...

The standard new Keynesian monetary policy problem is presentable as a set of linearized equations, for values of endogenous variables relatively close to their steady-state. As a result, only three possibilities are admissible in terms of long-term dynamics: the equilibrium may be a stable...

We make a case for the usefulness of an optimal control approach for the central banks’ choice of interest rates in inflation target regimes. We illustrate with data from selected developed and emerging countries with longest experience of inflation targeting.

The standard new Keynesian monetary policy problem is, in its original presentation, a linear model. As a result, only three possibilities are admissible in terms of long term dynamics: the equilibrium may be a stable node, an unstable node or a saddle point. Fixed point stability (a stable...

The paper reviews issues related to the zero lower bound (ZLB) on interest rates and argues that all of the following propositions are invalid: (1) in a ZLB situation, gshaping interest rate expectations is essentially the only tool that central bankers haveh (Bernanke, Reinhart, and Sack...

In recent years state space models, particularly the linear Gaussian version, have become the standard framework for analyzing macro-economic and financial data. However, many theoretically motivated models imply non-linear or non-Gaussian specifications or both. Existing methods for estimating...

The presence of the lagged shadow policy rate in the interest rate feedback rule reduces the government spending multiplier nontrivially when the policy rate is constrained at the zero lower bound (ZLB). In the economy with policy inertia, increased inflation and output due to higher government...

Can the central bank credibly commit to keeping the nominal interest rate low for an extended period of time in the aftermath of a deep recession? By analyzing credible plans in a sticky-price economy with occasionally binding zero lower bound constraints, I find that the answer is yes if...

There is a case, but there are also counter-arguments. With sufficient forward-looking behaviour among firms and households, price-level targeting can act as a powerful built-in stabiliser through automatic shifts in inflation expectations. This stabilisation mechanism reduces the need for large...
