- Description: The study examines exchange rate volatility and inflation in South Africa over the period of 1987- 2012 using annual data. With the use of VAR, ADF unit root testing and Johansen for cointegration the study examines the relationship between exchange rate volatility and inflation in South Africa. The study also examines other variables, which are Money Supply, Trade Openness, Real Interest Rate and Real Gross Domestic Product (RGDP), if they had an impact on inflation and had contributed significantly to inflation during the period under review. All macroeconomic variables were identified to have an impact on inflation in the long-run. Exchange rate volatility was identified as the main variable that had substantial impact on inflation rate. The study recommended the current system used by the authorities was working well, as they can pursue a countercyclical macro policy, but also continue to manage the float by intervening to stabilize the exchange rate. The reason for this recommendation was that because one of the advantages of floating exchange rate is freeing internal policy, with a floating exchange rate, balance of payments disequilibrium would be rectified by a change in the external price of the currency. However, with a fixed rate, curing a deficit could involve a general deflationary policy resulting in unpleasant consequences for the whole economy such as unemployment.

- Description: The fact that South Africa has a floating exchange rate policy as well as an open trade policy leaves the country’s import, producer and consumer prices susceptible to the effects of exchange rate movements. Given the central role that inflation targeting occupies in South Africa’s monetary policy, it becomes necessary to determine the nature of influence of exchange rate changes on domestic prices. To this end, this thesis examines the magnitude and speed of exchange rate pass-through (ERPT) to import, producer and consumer prices in South Africa. Furthermore, it explores whether the direction and size of changes in the exchange rate have different pass-through effects on import prices, that is, whether the exchange rate pass-through is symmetric or asymmetric. The paper uses monthly data covering the period January 1980 to December 2005. In investigating ERPT, two main stages are identified. The initial stage is the transmission of fluctuations in the exchange rate to import prices, while the second-stage entails the pass-through of changes in import prices to producer and consumer prices. The first stage is estimated using the Johansen (1991) and (1995) cointegration techniques and a vector error correction model (VECM). The second stage pass-through is determined by estimating impulse response and variance decomposition functions, as well as conducting block exogeneity Wald tests. The study follows Wickremasinghe and Silvapulle’s (2004) approach in estimating pass-through asymmetry with respect to appreciations and depreciations. In addition, the thesis adapts the analytical framework of Wickremasinghe and Silvapulle (2004) to investigate the pass-through of large and small changes in the exchange rate to import prices. The results suggest that ERPT in South Africa is incomplete but relatively high. Furthermore, ERPT is found to be higher in periods of rand depreciation than appreciation which supports the binding quantity constraint theory. There is also some evidence that pass-through is higher in periods of small changes than large changes in the exchange rate, which supports the menu cost theory when invoices are denominated in the exporters’ currency.
