Thesis (MDF)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Immigrant remittances have received increasing attention over the last couple of decades, due to the substantial financial inflows into developing countries, as their size and impact on the economies have experienced significant growth over a period of time. This study has investigated the relationship between financial development, specifically for the banking sector, and remittances for eight Sub-Saharan African (SSA) countries by utilising panel estimation techniques from 1993-2011. In this particular study, the investigation was focused on the association between remittances and the aggregate level of bank deposits (M2) and domestic credit to the private sector that represented financial development. For M2, the results showed that remittances are negatively correlated with money supply and it was not statistically significant for this equation. However, in terms of domestic credit to the private sector, a positive and significant determinant was found for remittances and financial development in these eight Sub-Saharan countries. It is recommended that policymakers should develop and implement sustainable policies to facilitate uninterrupted flow of remittances, strengthen financial institutions and sound macro-economic policies in order to attract more remittances through the banking sector.

Doctoral thesis submitted in fulfilment of the requirements for the award of Doctor of Philosophy The Graduate School of Business Administration, Wits Business School University of the Witwatersrand June, 2017 / Financial sector development has been projected to play a very significant role in economic growth through the provision of improved quality and quantity of financial services. While financial development–growth nexus has received much attention in the literature, important research gaps still remain largely in areas such as financial–real sector interaction in growth trajectory, threshold effects, finance–volatility–shocks linkages; and legal system–information asymmetry nexus. Knowledge of these relationships is extremely crucial in regulating the financial sector and conducting prudent macroeconomic policy more generally. Using sub–Saharan Africa (SSA) as a case, this thesis consists of four self–contained empirical essays each investigating a critical gap relying on several advanced econometric techniques. In the first essay, we examine the effect on economic growth when financial sector growth outstrips the solvency needs of the real sector. In this context, we find that more than two–thirds of our sampled countries in SSA have experienced at least one episode of excessive credit growth relative to real sector needs. While financial development supports economic growth, the extent to which finance helps growth depends crucially on the simultaneous growth of real and financial sectors. The elasticity of growth to changes in either size of the real sector or financial sector is higher under balanced sectoral growth. We also show that rapid and unbridled credit growth comes at a huge cost to economic growth with consequences stemming from financing of risky and unsustainable investments coupled with superfluous consumption fuelling inflation. However, the pass–through excess finance–economic growth effect via the investment channel is stronger. A good understanding of the optimal level of credit consistent with long run economic growth is needed as existence of an undisturbed equilibrated growth of real and financial sectors is a necessary condition for a smooth economic growth. By introducing a previously missing link, our findings resolve the seemingly conflicting and highly contested results in the finance–growth literature. The second essay investigates whether the impact of finance on growth is conditioned on the initial levels of countries‟ income per capita, human capital and financial development. While financial development is positively and significantly associated with economic growth, our evidence suggests that, in almost all the threshold variables, below a certain estimated threshold, financial sector development is positively and insignificantly related to growth. In other words, below the threshold level of per capita income, human capital and the level of finance, economic growth is largely insensitive to financial development while significantly influencing economic activity for countries above the thresholds. The main conclusion drawn is that higher level of finance drives long run growth and so is the overall level of income and human capital. In the third essay, we disaggregate volatility into its various components in examining the effect of financial development on volatility as well as channels through which finance affects these volatility components. What emerged is that while financial development affects business cycle volatility in a non–linear fashion, its impact on long run fluctuation is imaginary. More specifically, well–developed financial sectors dampen volatility. The findings also revealed that while monetary shocks have large magnifying effect on volatility, their effect in the short run is minuscule. The reverse, however, holds for real shocks. The channels of manifestation shows that financial development dampens (magnifies) the effect of real shocks (monetary shocks) on the components of volatility with the dampening effects consistently larger only in the short run. A key implication emanating from this essay is that, strengthening financial sector supervision and cross–border oversight may be very crucial in examining the right levels of finance and price stability necessary to falter economic fluctuations. In the final essay, the study re–interrogates the role of law in financial development in the light of evolving legal systems in SSA as well as how legal origin explain cross–country differences in economic volatility through its effect on information asymmetry. Our evidence suggests that legal origin significantly explains cross–country differences in financial development and economic volatility. More importantly, relative to civil law, English common law countries and those in Southern Africa have higher financial sector development both in terms of financial activity and banking efficiency on the back of lower volatility. While private credit bureau positively (negatively) affects financial development (economic volatility) with economically large impact for English legal legacy countries, the latter effect is contingent on the form of legal origin suggesting that, the establishment of information sharing offices per se may be insufficient in taming growth vagaries. The effectiveness of law is exceedingly relevant. At the policy front, maintaining more agile and effective legal systems that are responsive to changing financial landscape while forcing economic agents to improve information infrastructure is healthy for both financial sector development and macroeconomic stability. / MT2017

A thesis submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand in fulfilment of the requirements for the degree of Doctor of Philosophy. Wits Business School 4 November 2016 / Sub-Saharan Africa faces severe infrastructure deficits including in power generation, water facilities, transportation, and telecommunications. These deficits compound the socio-economic challenges of the most impoverished region in the world. It is estimated that funding of US$ 90 billion per annum is required to address infrastructure deficiencies. Other developing regions including Asia, the Middle East, and South America, have with varying degrees of success utilised the project finance framework to address similar infrastructure deficiencies, and also develop other commercial ventures. Africa has lagged behind in this respect, and still accounts for less than 3% of international project finance flows. The ability to attract and access international and domestic project finance capital, and execute the underlying ventures is an important opportunity to address the challenges noted above. The study contributes to knowledge by deepening our understanding of project finance in South Africa, Mozambique, and Zimbabwe in the following ways. Firstly, it offers a model through which to monitor key contextual factors that influence the success, failure, and shaping of project and infrastructure ventures. Secondly, it interrogates the main capital structure theories including the static trade off and pecking order theories, and their applicability and relevance for project and infrastructure finance in the selected jurisdictions. It then compares capital structure theory with actual practice of capital structure formulation in the 7 cases studies investigated. This yields important insights as to the most important factors influencing capital structure in project finance in the three selected countries. In particular the constrained supply of capital is observed as the top factor determining capital structure. It further enhances our understanding of why ventures using project finance in these countries may have significantly lower leverage than other similar ventures in developed regions of the world. Thirdly, the study extracts key insights into how stakeholder interactions evolve in the projects by applying stakeholder agency theory to project sponsors, managers, contractors, state institutions, and community organisations. Collectively these insights should contribute to attracting increased capital to project finance in Sub-Saharan Africa, and arranging projects with greater prospects of operational success. / MT 2017

The literature investigating the relationship between stock market returns and inflation is long and has produced diverse findings. This thesis examines the nature of stock–inflation relations in Sub-Saharan countries whose stock markets were established before 1992. Evidence in this thesis shows that in the short term there is a positive relationship between stocks and inflation. Using the Johansen (1988) evidence, a long-run stock–inflation relationship is confirmed only in Nigeria and South Africa, where it is found to be negative. However, accounting for structural breaks provides evidence for a long-run relationship in Botswana, Ghana and Kenya. The evidence of the effects of regimes in the relationship is further supported by a nonparametric cointegration analysis which finds a long-run relation in countries where the Johansen (1988) method had failed. Unexpected inflation is also found to be related to stock returns in Botswana, Ghana, Kenya, Nigeria and Mauritius, which raises concerns about the use of month-end stock data in analysing this relationship. The thesis confirms the existence of hidden inflation in Kenya, Mauritius, Nigeria and Zimbabwe. Imported inflation, interest rates and the exchange rate are found to have useful information about inflation movements in Sub-Saharan Africa.
