M.Comm. / The South African investment management sector is considered well-developed with local fund managers managing approximately ZAR2.1 trillion in assets as at the end of June 2009. These assets grew to approximately ZAR2.4 trillion as at the end of June 2010. The majority of these assets are made up of institutional funds which include retirement funds. Retirement-fund investment savings have a profound impact on the country’s economic welfare not only because it provides income to a large number of aged people in South Africa, but also because it contributes to the country’s overall economic wellbeing. Therefore, one of the biggest challenges within the retirement fund industry is to ensure that retirement-fund savings are invested in an optimal way.

Recently socio-hydrology models have been proposed to analyze the interplay of community risk-coping culture, flooding damage and economic growth. These models descriptively explain the feedbacks between socio-economic development and natural disasters such as floods. Complementary to these descriptive models, we develop a dynamic optimization model, where the inter-temporal decision of an economic agent interacts with the hydrological system. We assume a standard macro-economic growth model where agents derive utility from consumption and output depends on physical capital that can be accumulated through investment. To this framework we add the occurrence of flooding events which will destroy part of the capital. We identify two specific periodic long term solutions and denote them rich and poor economies. Whereas rich economies can afford to invest in flood defense and therefore avoid flood damage and develop high living standards, poor economies prefer consumption instead of investing in flood defense capital and end up facing flood damages every time the water level rises like e.g. the Mekong delta. Nevertheless, they manage to sustain at least a low level of physical capital. We identify optimal investment strategies and compare simulations with more frequent, more intense and stochastic high water level events.

El impacto de las nuevas tecnologías junto con los nuevos modelos de negocio está cambiando la industria del sector financiero, uno de los nuevos emprendimientos de innovación son las criptomonedas, siendo la Bitcoin la más popular, ya que su principal característica es ser descentralizada pudiendo ser utilizada en diferentes partes del mundo. La presente investigación tiene por finalidad determinar si hay una relación estadística entre el precio de la Bitcoin y los activos de inversión e índices del mercado financiero durante el periodo de Enero 2015-Diciembre 2018, considerando la alta volatilidad del precio en los últimos dos años; y, si las variables hasta ahora conocidas como justificantes del precio serán las mismas para esta actualización del estudio de la criptomoneda considerando la posible presencia de una burbuja financiera en la Bitcoin. Para el desarrollo del modelo se empleó la metodología de investigación cuantitativa mediante un modelo de regresión. EL resultado fue un grado de asociación considerable con el Euro, Yuan, S&P500 y Petróleo WTI; sin embargo, al desarrollar el modelo estadístico se concluyó que las variables seleccionadas nos presentan causalidad sobre el precio de la criptomoneda. / The impact of new technologies along with new business models is changing the industry of the financial sector, one of the new innovation ventures are the cryptocurrencies, being the Bitcoin the most popular, as its main feature is to be decentralized and can be used in different parts of the world. The present investigation has for purpose determine if there is a statistical relation between the Bitcoin´s price and the assets of investment and indexes of the financial market during the period of January 2015-December 2018, considering the high volatility of the price in the last two years; and, if the variables till now known like justifying of the price will be the same for this update of the study of the criptocurrency considering the possible presence of a financial bubble in Bitcoin. For the development of the model there was used the methodology of quantitative investigation by means of a model of regression. The result was a degree of considerable association with the Euro, Yuan, S&P 500 and Oil WTI; nevertheless, on having developed the statistical model concluded that the selected variables us not present causality on the price of the criptocurrency. / Tesis

Thesis (M.M. (Finance & Investment)--University of the Witwatersrand, Faculty of Commerce, Law and Management, Wits Business School, 2016. / Foreign investment, both in the form of direct, long-term and portfolio flows, is necessary for the development of countries. Fund managers are regulated to allocate funds from their portfolios to countries that are in Emerging Market Indices, following the guide laid out by MSCI and Standard & Poor Dow Jones Indices. Accordingly, countries that graduate into these indexes are defined as ‘investable’. This study examined the underlying factors that both foreign direct and portfolio investors consider when making investments. The factors were then regressed against the countries that had graduated into the emerging market indices to determine which characteristics are necessary for qualification into the index. The sample size included 22 countries common to MSCI and S&P Dow Jones Emerging Market Indices and 28 countries that were economically similar but did not qualify for entry into the index. The study revealed that inflation has negatively correlated with the odds of a country’s graduation into the index. Additionally, of the different types of infrastructure considered, human capital had the largest marginal impact on a country’s investability, while taxation laws and foreign exchange were found to be statistically insignificant. Political stability was found to be negatively correlated with the country’s odds of graduation. Lastly, foreign investors preferred investing in countries with higher sovereign credit rankings and placed high emphasis on the size of financial markets. Policy makers of countries that intend to graduate into the emerging market indices should therefore place emphasis on macroeconomic stability of their economies. They should aim to develop resources, through development of human capital. Finally, they should aim to improve and maintain their credit ratings over time. / DH2016

The goal of this paper is to extend the results of Bayraktar and Young (2006) on minimizing an individual's probability of lifetime ruin; i.e. the probability that the individual goes bankrupt before dying. We consider a scenario in which the individual is allowed to invest in both a domestic bank account and a foreign bank account, with the exchange rate between the two currencies being modeled by geometric Brownian motion. Additionally, we impose the restriction that the individual is not allowed to borrow money, and assume that the individual's wealth is consumed at a constant rate. We derive formulas for the minimum probability of ruin as well as the individual's optimal investment strategy. We also give a few numerical examples to illustrate these results.

Submitted in accordance with the requirement for the degree of Doctor of Philosophy In Business Administration At the University of the Witwatersrand Johannesburg / Generating sufficient domestic revenues to finance economic growth has been a critical hurdle for many African countries and, for decades, foreign capital has complemented domestically generated resources to finance growth. However, global financial crises over the past few decades tend to curtail, if not dry up the flow of capital to African governments. The unreliability of foreign capital with its attendant strings and sudden stops in the event of economic and political crisis has spurred the need for alternative sources of financing development. Despite the realisation that bond markets provide a viable source of funds for the African continent, the literature on the importance of bond market development and its interaction with other sources of funding remains underexplored. Moreover, the sparse empirical literature about bond market development in Africa is vague and largely overlooked. At the same time, knowledge of African bond markets is vital for channelling funds not only to efficient agents in particular, but also for fostering transparency and the flow of information within the continent’s capital markets. This thesis endeavours to address the vacuum apparent in extant literature and proposes a theoretical framework through a thorough assessment of the determinants of bond market development in African emerging market economies. The thesis examines four critical pillars of bond market development: (a) the environment for the creation of bond markets; (b) the relative performance and characteristics of bond markets across and within developing and developed economies; (c) the modelling of bond markets and (c) the institutional factors that underpin the efficient functioning of bond markets. Using macroeconomic, social, institutional and historical data on local currency bond markets from 26 African economies and 49 listed firms, this thesis extends previous studies on bond market determinants through tighter robustness measures by accounting for downside risk in a generalized methods of moments (GMM) and a feasible generalized least squares estimator (FGLSE) framework. Further, differential analysis of government and corporate bond markets are carried out, given their different investment horizons and issuance. The results suggest that from a macroeconomic perspective, inflation, central government debt, GDP, external debt, GDP per capita and fiscal balance are important drivers of local currency bond market development in African economies. Moreover, political unrest, governance, religion, former colonial ties and culture are institutional factors that exert statistically significant effects on local currency bond market performance in Africa. From a demand viewpoint, the study finds that firm level factors that influence bond market performance are firm risk, size, profitability and age. The results from this study are of importance to capital market participants, investors, regulators and policy makers who seek to address the perennial constraints to development occasioned by lack of capital. A number of policy measures for boosting bond market performance such as stable macroeconomic environments, reform of capital market rules and cross listing are discussed in the final chapter.

Thesis (M.M. (Finance & Investment))--University of the Witwatersrand, Faculty of Commerce, Law and Management, Graduate School of Business Administration, 2013. / Unit trust investment looks cosy and attractive from the surface, but a detailed understanding of unit trust and its performance can be daunting. Having discussed the evolution of mutual funds in the US and other industrial and financially sound countries; it is concerning that not much has been done in terms of research works on the South Africa unit trust industry’s performance. Several studies have been aimed at investigating the investment in mutual funds relative to mutual fund returns, but an extensive study on the performance of active unit trusts against their bench-marking index is still lacking. This study contributes to the debate by conducting a detailed study of the performances of mutual funds in the last two decades and also what the global investment fund witnessed over this period, with particular interest in the South African market. Another contribution of this study was to provide reasons for the slow growth of investment funds in South Africa; this study attempts to ascribe reasons as to why this has been so. This study used three different performance measures (namely: the nominal returns, Sharpe Ratios and CAPM Alphas) to test the possibility of superior performance by the market or the funds. In order to carry out this detailed analysis of the performance of unit trusts, these performance tests were applied individually to the net returns obtained from a sample of 64 South African domestic general equity unit trusts, covering the 20-year period from January 1st 1992 to December 31st 2011. This 20-year period was further divided into 7 different periods of four 5-year periods, two 10-year periods and the whole 20-year period. This was done to avoid survivorship bias. In all of the periods, strong evidence of superior performance by the domestic general equity unit trust over the market could not be found. Furthermore, several reasons were deduced form the study as to investment funds continue to experience slow growth. Some of the reasons include the following: cost of index fund, investor’s sentiments, and commissions amongst others. Finally, having said all these, outperformance, perhaps may not be the main objective of unit trusts. The findings of this study may not have provided strong evidence of outperformance, it however reveal that there is a need for unit trusts to evaluate the costs and benefits involved in their trading activities in order to provide investors with maximum possible returns for the level of risk they take.

Thesis (M.M. (Finance & Investment))--University of the Witwatersrand, Faculty of Commerce, Law and Management, Graduate School of Business Administration, 2013. / This study investigates the current private equity market in African frontier markets as well as inherent investment opportunities in these African frontier markets. The research includes an analysis of, inter-alia, the following: the development of capital markets in Africa, the classification of African frontier markets, the measurement of liquidity, the relationship between liquidity and asset prices and the history of private equity. This study will highlight to policymakers both in African and in donor capitals the need to implement strategies that will support investment (especially private equity investment) into the continent. The research carried out in this study should contribute to a better understanding of illiquidity risks of African frontier markets and show how these can be mitigated. This study will also provide key information on African frontier markets to investors and fund managers in order for them to understand that a typical investment strategy for investing in developed markets cannot be applied to frontier markets. The study analyses data of listed stocks on selected African stock exchanges and compares this to data for similar stocks listed on developed world stock markets to examine the relationship between liquidity, earnings multiples and market capitalisations for these stocks. Interestingly, results show that, while there is no relationship between the liquidity of stocks and the Price Earnings (PE) multiples of stocks, there is strong evidence to suggest that a relationship exists between the liquidity of stocks and the Enterprise Value to EBITDA (EV/EBITDA) multiples of stocks. Furthermore, we find strong evidence that African frontier market stocks are significantly less liquid and have lower earnings multiples than stocks with similar market capitalisations listed on stock exchanges in the developed world.

Thesis (M.M. (Finance & Investment))--University of the Witwatersrand, Faculty of Commerce, Law and Management, Graduate School of Business Administration, 2013. / The subject of this study posits the profitability of an investment strategy focused on high-dividend yielding securities from the South African stock market over the period of 10 years from 2002 to 2012. The study follows an expected dividend yield model, similar to the model proposed by Hsu and Lin (2010), for the construction of a high-dividend yielding portfolio. Financial data of listed companies’ dividends and other financial information is used to estimate these expected current dividend yields by employing multiple regression analysis. It is suggested that these expected yields better reflect companies’ future profitability than traditional current dividend yields. The results of the study show that the performance differences between the portfolios based on the expected dividend yield model and the benchmark portfolios are significant; however the tests of the model suggest that the model is not a good fit for the data.

This article intends to contribute with the reflection upon the theories that link FDI with social and economical development. For this purpose, the meanings of the expression “human and economical development” will be briefly reviewed, and later it will be approached along the theories on the relation of FDI with development. The theories are used as a support in order to reach this article’s goal of pointing out the FDI impacts on labour conditions on the private security multinational G4S in Mozambique, thus examining the impacts of this sort of FDI towards the country’s human development.
