Abstract:
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 well as asymmetric. The main findings are that the monetary authorities react in a passive manner when inflation is within the target band and become increasingly aggressive when it deviates from the target band and that they react with the same level of aggressiveness regardless whether inflation overshoots or undershoots the inflation target band, that is, the monetary authorities’ response towards inflation is zone symmetric. The second major finding shows that the monetary authorities’ response to output fluctuations is asymmetric such that they react more aggressively to negative deviations of output from the potential, therefore weighing more business cycle recessions versus expansions.
