Inflation Targeting, Exchange Rate Distortion and Output Stabilisation A Case of Zimbabwe Disinflation

Abstract

Inflation targeting (IT) is practised in many countries and the real effects of strict inflation targeting were investigated on several occasions and less on other variants of IT. The study investigates the effects of inflation targeting lite on output. In particular, the compatibility of inflation targeting lite with managed exchange rate regime on output stabilization. The inflation targeting regime, the operating environment and exchange rate regimes were reviewed for Zimbabwe. An ARDL model was adopted as the empirical strategy to investigate the compatibility problem and the real effects of IT lite. Modelling output as output gap, inflation targeting lite and the exchange rate regimes were found to be inconsistent with output stabilization. IT lite and exchange rate premium increased the output gap, however the interaction between IT lite and exchange rate premium had negative effects on output. These results hold for both the short run and long run. However, considering the official rate and parallel rate separately, parallel rate has a negative effect but its interaction with IT has positive effects. The study recommends that developing countries should consider the exchange rate systems before the adoption of IT as a monetary policy framework. A floating exchange rate seemed to be compatible with IT lite.
