- Description: This study examined whether or not financial intermediation can explain the variations in the savings-investment ratio in South Africa during the period 1990 to 2012. The study specifically tests the McKinnon Conduit Effect hypothesis which states that increasing interest rate raises the capacity of financial savings via financial intermediaries based on data from South Africa. Apart from informal graphical test, this study employed formal tests such as the Augmented Dickey-Fuller and Phillips Perron stationarity tests to test the properties of the variables considered, including interest rates, for stationarity. In order to ascertain the long-run and short-run dynamics between its variables, the Johansen co-integration test is utilized, while the Error Correction Mechanism is also employed. Results from the study state that financial assets (a proxy for financial intermediation), income and real interest rate all positively impact the savings-investment ratio. Additionally, short-run analysis results showed that income, financial assets and real interest rates positively influence the savings-investment ratio. Real interest rates were seen as being both positive and statistically significant. Therefore the study recommended that the financial services sector and the South African Reserve Bank (SARB) should work together as this will result in the improvement of efficiencies in price discovery with regards to bank charges, access to banking facilities and the timely provision of services in order to encourage savings (for investment purposes) in the South African economy.

Value and size investment strategies: evidence from the cross-section of returns in the South African equity market

- Description: Value and size related equity investment strategies are supported by a large body of empirical research that shows a persistent premium, both longitudinally and crosssectionally. However, the competing rational and behavioural finance explanations for the success of these strategies are a subject of debate. The rational explanation is that the premium earned on value shares or shares of small companies can be attributed to higher risk. Behaviouralists argue that such shares are not riskier and attribute the premium to cognitive errors and biases in human decision making. The purpose of this study is to determine, firstly, whether the value and size premium exist in South Africa during the period July 2006 to June 2012, which includes one of the worst equity market crises in history. Secondly, this study sets out to determine whether the premium earned on value and size strategies are adequately explained by the principles of rational finance theory. To provide evidence regarding the existence of the value premium and size effect, returns are analysed, cross-sectionally, on portfolios of shares sorted by value and size. For evidence of a rational explanation, returns are regressed on value and size variables, and the relative riskiness of value and small companies is analysed. The results show evidence of a value premium in portfolios of small companies, but not big companies. The size effect is found not to be statistically significant. While regressions do show significant relationships between value and size variables and returns, these variables are found not to be associated with higher levels of risk. The conclusion is that the evidence does not support a rational, risk based explanation of the returns

The impact of capital flows on real exchange rates in South Africa

- Description: The neoclassical theory suggests that free flows of external capital should be equilibrating and thereby facilitating smoothening of an economy's consumption or production patterns. South Africa has a very low savings rate, making it highly dependent on capital inflows which create instability and volatility in global markets. A policy dilemma is undoubtedly evident: capital inflows help to cater for the domestic low savings and at the same time the inflows pose instability, a threat on competitiveness and volatility challenges to the same economy due to their impact on exchange rates. The question is: are all forms of capital flows equally destabilizing? Since studies based on South Africa considered only the relationship between aggregate capital flows and real exchange rate, modelling individual components of capital flows could enlighten policy formulation even further. The composition of the flows and their effects on the composition of aggregate demand determine the evolution of real exchange rate response to surges in capital flows. Through co-integration and vector error correction modelling techniques applied to South African data between 1990 and 2010, the study found out that foreign portfolio investment exerts the greatest appreciation effect on the South African real exchange rate, followed by other investment and finally foreign direct investment. Thus the impact of capital flows on real exchange rate in South Africa differs by type of capital. This presents varied policy implications.

The impact of real exchange rates on economic growth: a case study of South Africa

- 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.

Volatility and the risk return relationship on the South African equity market

- Description: The volatility of stock markets has important implications for investment decision making, financial stability and overall macroeconomic stability. This study examines the risk-return relationship as well as the behaviour of volatility of the South African equity markets using both aggregate, industrial level and sector level data. The study is divided into three parts. The first part investigates the behaviour of volatility in each of the industries, sectors and the benchmark series focussing on whether volatility is symmetric or asymmetric. Subsequently we investigate which, among the GARCH family of models appropriately captured the riskreturn relationship under which distributional assumption. The second part examines the riskreturn relationship on the SA stock market. The third part examines the long term trend of volatility and whether volatility significantly increases during financial crises and during major global shocks. The GARCH-M, EGARCH-M and TARCH-M models under the Gaussian, Student –t and the GED are used. The findings this study makes are as follows: firstly, there is no clear relationship between risk and return. Secondly, volatility is asymmetrical, implying that bad news has a greater effect on volatility than good news in the South African equity market. Thirdly, the TARCH-M model under the GED was found to be the most appropriate model. Fourthly, volatility increases during financial crises and major global shocks. Overall, volatility is generally not priced on the South African equity markets. Thus, both local and international investors need to consider other factors that influence returns such as skewness. The general increase in volatility during financial crises and major global shocks poses a major concern for policy makers as this may cause financial instability. Thus policy makers need to be mindful of the behaviour of volatility in the South African equity market in response to external shocks.
