Estimating Monetary Policy Rules when the Zero Lower Bound on Nominal Interest Rates is Approached

Abstract
Monetary policy rule parameters estimated with conventional estimation techniques can be severely biased if the estimation sample includes periods of low interest rates. Nominal interest rates cannot be negative, so that censored regression methods like Tobit estimation have to be used to achieve unbiased estimates. We use IV-Tobit regression to estimate monetary policy responses for Japan, the US and the Euro area. The estimation results show that the bias of conventional estimation methods is sizeable for the inflation response parameter, while it is very small for the output gap response and the interest rate smoothing parameter. We demonstrate how IV-Tobit estimation can be used to study how policy responses change when the zero lower bound is approached. Further, we show how one can use the IV-Tobit approach to distinguish between desired policy responses, that the central bank would implement if there was no zero lower bound, and the actual ones and provide estimates of both.

The Extreme Risk Problem for Monetary Policies of the Euro-Candidates
Hubert Gabrisch, Lucjan T. Orlowski
Abstract
We argue that monetary policies in euro-candidate countries should also aim at mitigating excessive instability of the key target and instrument variables of monetary policy during turbulent market periods. Our empirical tests show a significant degree of leptokurtosis, thus prevalence of tail-risks, in the conditional volatility series of such variables in the euro-candidate countries. Their central banks will be well-advised to use both standard and unorthodox (discretionary) tools of monetary policy to mitigate such extreme risks while steering their economies out of the crisis and through the euroconvergence process. Such policies provide flexibility that is not embedded in the Taylor-type instrument rules, or in the Maastricht convergence criteria.

Estimating Monetary Policy Rules for South Africa
Tobias Knedlik
South African Journal of Economics,
2006
Abstract
The paper combines the estimation of the Monetary Conditions Index (MCI) with the theoretic modelling of optimal monetary policy in South Africa. The idea that monetary policy is not only interested in optimal monetary conditions but also in external stability, provides the basis for the analysis. The paper introduces the concept of the MCI and estimates the relative influence of interest rates and exchange rates on the output gap. The estimated weights are 1.9:1. This estimation result is used to specify operating target rules for South African monetary policy.

Abstract
THE AIM OF THIS PAPER is to combine the estimation of the Monetary Conditions Index (MCI) with the theoretic modelling of monetary policy rules for open and emerging market economies using the example of South Africa. The idea that monetary policy is not only interested in optimal monetary conditions but also in external stability, constitutes the basis for the analysis. This idea emerged from studying currency crises that are caused by inadequate monetary policy and in particular from the experience of the Asian crisis of 1997/98 and its worldwide spread also to South Africa. The Monetary Conditions Index is a potentially useful tool for the development of monetary policy rules.
