- Description: The goal of this study was to determine whether asymmetric price transmission (APT) exists between the prices of South African UG-2 Chrome ore, Charge Chrome, Nickel and Chinese Domestic 304 Stainless steel Cold Rolled Coil prices. Monthly time series data for the period January 2009 to July 2019 was analysed. The Non-Linear Autoregressive Distributive Lag (NARDL) model was applied to test for the presence of price asymmetry between the four variables. Firstly, it was observed that the four variables are cointegrated in the long-run. Secondly, no evidence of price asymmetry was found to be present within the Stainless steel supply chain. The reason for this is most likely due to the extremely close-knit and highly concentrated nature of this industry at each level within the supply chain. The industry can be very opaque to external observers even though the distribution of pricing information is very efficient for participants within the industry.

- Description: This study explores the impact incentive effects have on the level of effort exerted by professional men and women tennis players. Understanding what impact incentives have on tennis players can allow for greater understanding of the impact incentives have in the workplace and how employees react to different incentive schemes. The study makes use of data from both the ATP and WTA tour of every tournament played during the 2016 season. This includes player statistics, tournament statistics and in-game statistics from the quarter-finals, semi-finals and finals of each tournament in an attempt to account for initial seeding effects. This provides a total of 440 ATP matches and 389 WTA matches for an overall sample size of 829 professional tennis matches. The findings from this study illustrate in the last three rounds of all the tournaments played, for both male and females, money is not considered to be a key motivator for players. The ATP and WTA results suggest that competitors do not alter their effort levels depending on the level of the tournament. This illustrates that players exert similar effort levels regardless of the amount of money or ranking points available. The outcome of the findings supports that of the capability effect of heterogeneity on players’ performance. This means that the outcome of a match is linked more to the abilities of the competitors involved as opposed to the incentives available. Thus, players will adjust their effort levels according to their opponent and not because there are more money or ranking points available. This suggests that both the ATP and WTA should aim to reduce the differences in abilities amongst the players in an attempt to raise the attractiveness of the sport. Overall, the findings from this study illustrate that the capability effect outweighs that of the incentive effect.

- Description: A key economic issue for government is the ability to effectively match electricity supply to electricity demand, because of the substantial economic losses in the case of where there is too little supply, or the waste of scarce resources where there is too much supply. In the case of South Africa, this issue, the importance of which was highlighted by the power shortages and associated “rolling blackouts” experience in 2008, has led to the creation of the Integrated Resource Plan (IRP) as a means to decide how energy policy will be developed. Recently, however, the IRP 2010 and its subsequent 2013 and 2016 (draft) updates have been criticised as being too optimistic in regards to their projections of economic growth and electricity demand, making the recommendations in these documents to be flawed. Using monthly data from January 1990 to May 2017, together with Autoregressive Distributed Lag (ARDL) bounds testing for cointegration, this paper measures changes in the elasticity of electricity demand as a result of the massive price hikes over the past decade. Thereafter, the implications of changed electricity as well as possibly lower Gross Domestic Product (GDP) growth in the future for forecasts of possible future demand for electricity are examined. From these revised forecasts, it is possible to make appropriate recommendations in regards to electricity supply policy for South Africa including what possible energy mix is needed as well as the requirements for creating new supply to meet possible future demand. It is concluded that future electricity demand is likely to be much lower than forecast in the IRP 2010 and IRP 2013 documents. The degree of uncertainty in electricity demand growth suggests that large-scale increases in supply capacity taking years to construct, such as coal or nuclear, should be avoided. Small, incremental increases in supply that are able to come on stream swiftly, such as gas, solar and wind power, are likely to be more appropriate for meeting South Africa’s future needs.

- Description: Suicide is a major public health issue and imposes substantial economic cost on society every year. For example, the World Health Organisation has estimated that there are over one million completed suicides every year, of which about 75% occur in middle and low income countries. In South Africa, suicide is one of the leading causes of non-natural death, but remains under-researched from an economic point of view due to limited data availability. Using monthly data for the period 2006-2015, this study explores whether there is a relationship between suicide and the South African business cycle. This is further broken down to examine how, if at all, this relationship with the business cycle differs across age-, gender-, and racial groups. The primary source of data for suicide and demographic groups were obtained from Statistics South Africa’s Mortality and Causes of Death Data from Death Notification released since 2006. The coincident indicator was used as a proxy for the business cycle as it represents the business cycle in real time. Using an autoregressive distributed lagged model (ARDL), a long run relationship was established with suicide being a function of the coincident indicator, divorce and fertility rate. The findings of this paper show that the overall suicide rate moves with the South African business cycle (i.e. pro-cyclical relationship) in the long run. This relationship holds for males, the black population group and the 15-29 and 30-44 age categories. In addition, the divorce rate had a positive and significant relationship with the overall suicide rate, as well as suicide among the black population group and for the 30-44 age category, whereas fertility rates had no significant relationship with suicide.

- Description: This study explores the impact of good news and bad news on South Africa’s sectoral stock return volatility using an asymmetric GARCH analysis. Understanding the different impact of news on stock return volatility in different economic sectors has important implications for investors’ risk management practices, portfolio allocation strategies and asset pricing. The study employs data of daily closing prices for nine sectors and three benchmark indices for the period 2nd January 1997 - 17th August 2016. The data was split into sub-samples of pre-, during and post-global financial crisis, as well as the overall sample period. The incorporation of sub-samples was to help explain the outcomes of the overall sample period. To capture the different impact of good news and bad news on stock return volatility for each sector, asymmetric GARCH models namely, TGARCH and EGARCH were employed. The findings from this study revealed that volatility asymmetry was present in all sectors and benchmark indices of South African equity market. Bad news had more impact on stock return volatility for all sectors except the Oil and Gas sector, than good news of the same magnitude. In the Oil and Gas sector, good news was found to have an amplified effect on return volatility compared with bad news of the same magnitude. High volatility persistence was also found to be present in the Consumer goods, Financials, Industrials, All-share index and Mid-cap index. High differential impact of good and bad news were found in the Industrials, Financials, Basic materials, Consumer goods and the All-share index. Since the main objective of this study was to provide explanations of volatility asymmetry found in the South African sectors, the following were proposed as possible explanations of the findings. Within sectors, volatility asymmetry was explained by financial leverage, the role of the media, loss-averse investors and the behaviour of traders (overconfidence and extrapolation bias). Volatility asymmetry across sectors was explained by information flow, the uneven distribution of information by the media, investor sentiments, investor expectations and trading volumes. Overall, the results indicate that the stock return volatility of individual sectors of the South African equity market is driven mainly by bad news (except for Oil and Gas) and that leverage effects exist in all the sectors and in the benchmark indices.

- Description: This thesis investigates the nature and strength of the relationship between short-, medium-, and long-term real interest rates and capital investment spending at both the aggregate and disaggregate levels in South Africa in order to determine whether changes in the real interest rate affect the level of capital investment in the economy. This thesis used quarterly data for the period 1987 to 2013. VAR modelling, variance decompositions, impulse response functions and Granger causality tests are used to explore the nature and strength of the relationship between interest rates and investment spending. It is found that interest rates explain very little of the variation in investment spending and seem to have little impact on investment (of any type). Furthermore, short-, medium- and long-term interest rates have different effects on the level of investment spending. A rise in short-term interest rates appears to decrease the level of investment spending in the long-run, whereas a rise in long-term interest rates results in an increase in investment.

Water service delivery in Harare: a willingness to pay (WTP) analysis

- Description: In 2008-2009, Harare (Zimbabwe) was the centre of the worst cholera outbreak in Africa in the past fifteen years. A key reason cited was the lack of adequate water service delivery by the Harare City Council (HCC). Harare requires an optimum supply of 1 400 mega litres (ML) of water daily but the HCC has capacity to produce 650ML and after leakages and theft, only 400ML reaches consumers. This inadequacy compromised the hygiene of residents and forced them to resort to unsafe water sources. Coupled with a failing healthcare system, the outbreak resulted in over 4 000 deaths and further affected 100 000 people. The HCC attributes its poor service delivery to the lack of funds rendering them unable to adequately increase capacity and refurbish existing infrastructure (treatment plants and pipelines). This thesis serves to explore whether the residents of Harare (and surrounding satellite towns) would be willing to pay monthly contributions towards the USD$2.5 billion needed for various water capacity and infrastructure projects to ease the water crisis in Harare. The study analyses the water problem using a framework on the typical stages of water provision. The research also places an emphasis on the key social, economic and political factors that are contributing to the problem in Harare. Upon closer inspection, it was seen that the financial problems that the HCC is having are not only due to the economy, but poor management and transparency structures are also to blame. For various reasons, the government has largely lost its credibility with its citizens, leading some to conclude that the government’s actions reflect those of a predatory state. The contingent valuation method (willingness to pay-WTP) was used in conjunction with the dichotomous choice referendum. The binary probit model was used to help assess the degree to which different variables influenced the respondent’s decision to contribute to the needed funds. In spite of the seeming lack of trust, it was found that approximately 66.19% of the respondents were willing to pay. Amongst those willing, the mean willingness to pay amount was approximately USD$7 monthly per household.

- Description: Since its inception, consumption behaviour theory has developed to account for the important social aspect that underpins or at least to some extent can be used to explain consumption behaviour. Modern consumption behaviour theory is anthropocentric in nature, with people and societal influence at the forefront of the theory. To date, empirical studies on consumption behaviour of cultural activities (for example, music and arts), entertainment and sport have used Bourdieu’s (1984) omnivore/univore theory to suggest that consumption of leisure activities is bound up in social ties. To date, no such investigation has been conducted in the context of sport in South Africa. The aim of the study therefore is to investigate whether South African cricket spectators are sporting omnivores or univores, thus, essentially investigating whether sports consumption behaviour in South Africa is bound up in social ties. A number of positive economic and social ramifications could result from gaining a holistic understanding of sports consumption behaviour in South Africa. Given these ramifications, the secondary goal of the research is to identify motives for consumers making specific sport consumption decisions, and determining whether certain characteristics can be attributed to these consumption decisions. Recommendations based on the findings of the research could help various stakeholders understand sports consumption patterns in South Africa, which could in turn lead to the realization of positive economic and social benefits. The study made use of a questionnaire, administered at four different limited overs cricket matches in the 2012/13 cricket season, to obtain a range of responses reflecting specific types of consumption behaviour as well as motives for consumption decisions of cricket spectators in the Eastern Cape. Using individual binary probit models and post estimation F-tests, the results indicate that consumption behaviour of sport within South Africa predominantly differs on the grounds of education and race. This suggests that there are aspects of social connotations underpinning sports consumption behaviour within South Africa

- Description: This study analyses whether the advent of strike action has an effect on the value and volatility of the South African Rand compared with the US Dollar. The literature suggests that strike action can have a significant effect on the exchange rate in terms of either value or volatility, and consequences can result that cause inefficiencies in the economy; inhibiting employment and economic growth. Strike action has become common place in South Africa, with 2012 alone recording 99 strikes, 45 of which were “wildcat” or unprotected strikes. This study uses GARCH and Intervention Analyses to determine what the resulting effects of the strikes might be on the exchange rate. The analysis used ZAR/USD exchange rate data for the period January 2000 to October 2013, and covered 72 of the most significant strikes in terms of lost man-days. The results are mixed, suggesting that the effects of strikes do not always conform to expectations (increased volatility and a depreciation in the Rand), and that outside factors affecting the global economy may have a more significant effect on the exchange rate than strikes on their own.

- Description: This study analyses whether the advent of strike action has an effect on the value and volatility of the South African Rand compared with the US Dollar. The literature suggests that strike action can have a significant effect on the exchange rate in terms of either value or volatility, and consequences can result that cause inefficiencies in the economy; inhibiting employment and economic growth.

- Description: There has been a long search for the keys to development and economic growth in Africa. This study investigates the relationship between FDI and economic growth over the period 2000-2012 using data from 48 African countries. On the aggregate regional level FDI and economic growth were found to be positively correlated during this period. Using panel data econometric techniques and the Panel Granger Causality test, results revealed that a bi-directional causality relationship existed between FDI and GDP. Thus, the results suggest that GDP is a requirement for increased investment, and at the same time is the result of increased foreign investment. Thus, the conclusion is that African policy makers are justified in increasing their attempts to create an attractive business environment for foreign investors, as it is beneficial for economic growth.

- Description: This study aims to investigate the relationship between private saving and investment for South Africa using a Vector Error Correction Framework. Saving and investment are considered to be important factors for sustainable economic growth in the country, particularly as these variables have been recorded at significantly lower levels than those of other developing nations. By examining the direction of causality between saving and investment, the most suitable policy measures can be used in stimulating either savings or investment, and as a result aggregate growth. The study found a positive two-way causality to exist between these two variables, proving that both saving and investment-led policies are necessary in raising saving and investment levels. With the inclusion of credit extension as the third variable used to remove any variable bias, the study not only found credit extension to Granger cause private saving, but the reverse relationship was found to be present as well. This relationship was however found to be negative, confirming that lower borrowing constraints may have a negative effect on saving levels. The negative relationship between credit supply and private saving (substitution effect) proves that credit supply will only yield a positive result for savings if channelled through investment expenditure.

Modelling stock return volatility dynamics in selected African markets

- Description: Stock return volatility has been shown to occasionally exhibit discrete structural shifts. These shifts are particularly evident in the transition from ‘normal’ to crisis periods, and tend to be more pronounced in developing markets. This study aims to establish whether accounting for structural changes in the conditional variance process, through the use of Markov-switching models, improves estimates and forecasts of stock return volatility over those of the more conventional single-state (G)ARCH models, within and across selected African markets for the period 2002-2012. In the univariate portion of the study, the performances of various Markov-switching models are tested against a single-state benchmark model through the use of in-sample goodness-of-fit and predictive ability measures. In the multivariate context, the single-state and Markov-switching models are comparatively assessed according to their usefulness in constructing optimal stock portfolios. It is found that, even after accounting for structural breaks in the conditional variance process, conventional GARCH effects remain important to capturing the heteroscedasticity evident in the data. However, those univariate models which include a GARCH term are shown to perform comparatively poorly when used for forecasting purposes. Additionally, in the multivariate study, the use of Markov-switching variance-covariance estimates improves risk-adjusted portfolio returns when compared to portfolios that are constructed using the more conventional single-state models. While there is evidence that the use of some Markov-switching models can result in better forecasts and higher risk-adjusted returns than those models which include GARCH effects, the inability of the simpler Markov-switching models to fully capture the heteroscedasticity in the data remains problematic.

- Description: The finance industry is an extremely fast and complex world dominated by the Efficient Markets Hypothesis (EMH). This theory contains many assumptions which include that investors are rational utility maximisers and that market prices reflect all relevant economic information available to the public. However, over the years, a new form of financial literature known as behavioural finance has been gaining momentum. Behavioural finance seeks to bridge the gap between psychology and economics in an attempt to gain a better understanding of how markets react to different situations. Behavioural finance has also gained much attention in recent years due to the EMH’s inability to explain many economic anomalies. This study first considers the differences between behavioural finance theory and EMH theory before explaining how an individual’s mood has the ability to influence one’s risk taking preferences. Mood changes were also found to be linked to changes in the way an individual reacts to different situations, the way they thinks and processes thoughts. Negative events were also found to have a greater influence on an individual’s mood than positive events did, resulting in an asymmetric relationship between positive and negative results. This study then examines numerous studies indicating how non-economic events can have a statistical and significant influence on stock market returns before analysing previous literature where sport was found to influence market prices. The aim of this study is to determine if South African national sporting performance can influence investors in such a way that it has the ability to impact on market returns. Using standard event study methodology, this study determines the constant mean return using the daily All-Share price index on the JSE for the period of 1 January 1990 to 31 December 2010. This study focuses on three of South Africa’s most popular sports, namely soccer, cricket and rugby and examine if these three sports have the ability to influence market returns. Although there is some evidence of a relationship between stock returns and sporting performance in the descriptive analysis, the regression results indicate that sporting performance in South Africa does not significantly explain abnormal market returns on the JSE. The study provides a number of possible reasons for this finding and concludes by suggesting areas for future research.
