The persistence property of inflation is an important issue for not only economists, but, especially for central banks, given that the degree of inflation persistence determines the extent to which central banks can control inflation. Also, not only is the level of inflation persistence that is...

We examine the high-frequency response of the rand-dollar nominal rate within ten-minute intervals around five minutes before, five minutes after) official inflation announcements, and show that the rand appreciates (respectively, depreciates) on impact when inflation is higher (respectively,...

Based on a representation of policymaker’s preferences that capture inflation zone targeting behaviors, we estimate a flexible model of the monetary policy reaction function of the South African Reserve Bank (SARB). To address the current debate on the importance of financial asset prices in...

This paper estimates the optimal monetary authorities’ response to deviations of inflation and output from their target values for South Africa over the inflation targeting era. This is achieved using an empirical framework that allows the central bank’s policy preferences to be zone-like as...

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...

In order to address practical questions in credit portfolio management it is necessary to link the cyclical or systematic components of firm credit risk with the firm’s own idiosyncratic credit risk as well as the systematic credit risk component of every other exposure in the portfolio. This...

A simple empirical nonlinear framework is used to analyse monetary policy between 1983 and 2007 in South Africa, focusing on the policy of in?ation targeting introduced in Feb 2000, more precisely when the South African Reserve Bank (SARB) announced that an inflation zone targeting regime of...

In this paper we provide an in-sample assessment of how the South African Reserve Bank (SARB) sets policy rate in the context of both linear and nonlinear Taylor type rule models of monetary policy. Given the controversial debate on whether central banks should target asset prices for economic...

This paper is the ?rst one to analyze the ability of linear and nonlinear monetary policy rule specifications as well as nonparametric and semiparametric models in forecasting the nominal interest rate setting that describes the South African Reserve Bank (SARB) policy decisions. We augment the...

Research on tax elasticities in South Africa mainly employs linear models and shows that taxes evolve symmetrically irrespective of the economic cycle. This study extends this research to show that taxes behave asymmetrically and nonlinearly during expansions and contractions. Estimated linear...
