We test the concept of the Opportunistic Approach to monetary policy in South Africa post 2000 inflation targeting regime. Our findings support the two features of the opportunistic approach. First, we find that the models that include an intermediate target that reflects the recent history of...

We explore how the ECB sets interest rates in the context of policy reaction functions. Using both real-time and revised information, we consider linear and nonlinear policy functions in inflation, output and a measure of financial conditions. We find that amongst Taylor rule models, linear and...

A new test for non-linearity in the conditional mean is proposed using functions of the principal components of regressors.  The test extends the non-linearity tests based on Kolmogorov-Gavor polynomials (Thursby and Schmidt, 1977, Tsay, 1986, and Terasvirta, Lin and Granger, 1993), but...

It has been argued that the effect of a change in the monetary policy interest rate on aggregate demand may be larger at higher levels of indebtedness through its impact on cash flows. However, the extent of credit constraints may be at least as important, if not more so. In particular, monetary...

A new test for non-linearity is developed using weighted combinations of regressor powers based on the eigenvectors of the variance-covariance matrix. The test extends the ingenious test for heteroskedasticity proposed by White (1980), but both circumvents problems of high dimensionality and...

Recent work on policy rules under uncertainty have highlighted the impact of output gap measurement errors on economic outcomes and their importance in the formulation of appropriate policy rules. This paper investigates the reliability of current estimates of the output gap in Canada. We begin...

This paper presents empirical evidence on the behaviour of interbank lending in Germany after a monetary policy impulse. Our VAR analysis shows that following a monetary contraction, the banking system as a whole attracts additional funds from foreign banks. Whereas small cooperative and savings...

The current study examines the relationship between the world oil price and aggregate demand in a developing country, Ghana, via the interest rate channel by means of cointegration analysis. Results of the study indicate that oil price—by impacting the price level positively—negatively...
