- Description: This study is about whether the money supply in South Africa under a monetary policy regime of inflation‐targeting is exogenously or endogenously determined. The proposition of an exogenous money supply has been offered by monetarists, where the Central Bank determines the quantity of money supplied to the economy and this has a causal influence on income and credit extension. The endogenous money theory is a post‐Keynesian proposition whereby the money creation is determined by banks adjusting their responses to demands for credit‐money from economic agents. The data analysis is from 2000Q1 to 2010Q4 and entails the use of the variables monetary base (MB), domestic credit extension (DCE), M3, and gross national product (GDP). All variables are logged. The empirical tests conducted start with the Augmented Dickey‐Fuller unit root test to determine the variables order of integration. Johansen cointegration tests are done followed by Vector Error‐Correction Models (VECMs) and Granger causality tests to determine whether there is unidirectional or bidirectional causality between variables over the long and short‐run. Based on the results of the testing it was discovered that over the inflation‐targeting regime money supply in South Africa was endogenously determined. Furthermore, the data best supports the Accommodationist analysis of endogenous money as opposed to that of Structuralism and Liquidity Preference , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: This study examined the impact of real exchange rates on economic growth in South Africa. The study used quarterly time series data for the period of 1994 to 2010. The Johansen cointegration and vector error correction model was used to determine the impact of real exchange on economic growth in South Africa. The explanatory variables in this study were real exchange rates, real interest rates, money supply, trade openness and gross fixed capital formation. Results from this study revealed that real exchange rates, gross fixed capital formation and real interest rates have a positive long run impact on economic growth, while money supply and trade openness have a negative long run impact on economic growth in South Africa. From the regression results, it was noted that undervaluation of the currency significantly hampers growth in the long run, whilst it significantly enhances economic growth in the short run. As such, the policy of depreciating the exchange rates to achieve higher growth rates is only effective in the short run and is not sustainable in the long run. Based on the findings of this study, the researcher recommended that misalignment (overvaluation and undervaluation) of the currency should be avoided at all costs. In addition, the results of the study showed that interest rates also have a significant impact on growth and since interest rates have a bearing on the exchange rate, it was recommended that the current monetary policy in South Africa should be maintained.

- Description: The effectiveness of monetary policy in achieving its macroeconomic objectives such as price stability and economic growth depend on the monetary policy tools that are implemented by the Central Bank. Monetary aggregates are one of the tools that have been used as indicators of economic activity and as intermediate targets to achieve these economic objectives. Until recently, monetary aggregates have been questioned and criticised on their usefulness in monetary policy. This has been attributed to the economic, financial and technological developments that have distorted the relationship between monetary aggregates and major macroeconomic variables. This study investigates the relevance of monetary aggregation by comparing the traditional simple sum and Divisia index monetary aggregates which was constructed for the first time for South Africa using the Tornquist-Theil method. The Polynomial Distributed Lag model is employed to compare the performance of these monetary aggregates using their relationship with inflation and manufacturing index. Furthermore, the aggregates are compared in terms of their controllability and information content. Overall, the study found a very strong relationship between inflation and all the monetary aggregates. However, more specifically the results suggested that the Divisia indices are superior to the simple sum in terms of predicting inflation. The evidence further suggests that the Divisia aggregates provide higher information about inflation than the simple sum aggregates. Regarding the controllability of the monetary aggregates, the findings suggest that the monetary authorities can hardly control the monetary aggregates using monetary base. Finally, the relationship between manufacturing index and all the monetary aggregates was very weak.

- Description: This study investigates the contribution of bank credit extension to the private sector to inflation in South Africa, covering the period 1970:1-2006:4. The long-run impact of bank credit on inflation is investigated by means of the Johansen co integration model. The short-run ynamics of the inflation is subsequently modelled by means of the Vector Error Correction Model (VECM). Using the Johansen methodology, the study identifies two co integrating equations linking inflation and its eterminants. The results suggest that the long-run relationship between inflation and bank credit to the private sector is negative and statistically significant at 10% level. The determinants that are significant at 5% level are: money supply, real gross domestic product, the money market rate, rand/dollar exchange rate and imports. The results are consistent with previous findings. The speed of adjustment in response to deviation from the equilibrium path was found to be negative at 10.56% per quarter, which is consistent with findings by Ohnsorge and Oomes (2003) for Russia. Both the signs and the magnitude of the coefficients suggest that the co integrating vector describes a long-run inflation equation. The impulse response functions confirm the theoretical expectations except for the import prices. The most persistent and significant shocks observed are on impulse response functions of money supply and bank credit to the private sector. The variance decomposition results also suggest that inflation responds quicker to innovations from money supply and the money market rate. The overall results provide evidence that the surge in inflation is associated with an increase in money supply as well as the instability in exchange rate. The effects of exchange rate fluctuation on inflation are reflected through changes in import prices. Based on the results we conclude that an increase in bank credit during the period 1970:1-2006:4 had a negative mpact on inflation in South Africa.
