The financial effect of cross listing on Sub-Saharan African exchanges for Johannesburg Stock Exchange, (JSE), listed companies

Dabengwa, Vusisizwe Noel January 2017 (has links)
Thesis submitted in fulfillment of the requirements for the degree of Master of Management in Finance & Investment in the Faculty of Commerce, Law and Management Wits Business School at the University of the Witwatersrand 2017 / There are 29 formal stock exchanges on the African continent with 23 based in sub-Saharan Africa. The pace and stage of stock market development has varied among most of the countries as only four stock markets have more than 50 listed stocks; five have at least 20 listed stocks; and the remaining 14 have less than 20 stocks. The Johannesburg Stock Exchange (JSE) stands out in Africa as by far the continent’s largest, most liquid and best regulated market and is home to some of the continent’s largest and most sophisticated companies. Cross listing refers to the listing of ordinary shares of a firm on an exchange other than the stock exchange in its registered jurisdiction. There are 24 JSE listed companies that have cross listed on other Sub-Saharan African stock exchanges. The bulk of these, (14), have cross listed on the Namibia Stock Exchange, 3 cross listed on Botswana Stock Exchange, 1 on the Nairobi Stock Exchange, 1 on the Ghanaian Stock Exchange, 3 on the Malawian Stock Exchange, 1 on the Zambian Stock Exchange and 1 on the Zimbabwean Stock Exchange. The study establishes the possible reasons and benefits of cross listing on other sub-Saharan exchanges for JSE listed companies. The study also provides insight into the possible effects, (financial as well as any others), of cross listing on other sub-Saharan African exchanges that a number of JSE listed entities have experienced. The study uses financial information collected from a public platform, (Sharedata), to compute financial ratio’s to determine the financial implications of the JSE companies cross listing on other sub-Saharan exchanges. The effects of cross listing on the JSE companies are then measured using latent growth curve modelling and a paired t test. The study concludes that there is no evidence to suggest that there are financial benefits for JSE listed companies to cross list on other sub-Saharan exchanges. The study further suggests that JSE listed companies should rather consider cross listing for qualitative reasons rather for any quantitative reasons. / MT2017

The Impact of Mobile Money on Saving in Sub-Saharan Africa

Ruh, Carolyn January 2017 (has links)
Thesis advisor: S. Anukriti / Since the launch of M-PESA in 2007, mobile money has created the potential to increase financial inclusion by providing a safe and convenient place to store wealth. This paper analyzes the impact of mobile money on savings practices in Sub-Saharan Africa. Using 2015 survey data from Uganda, Kenya, and Tanzania, I find that mobile money account holders are 10.9 percent more likely to save than non-account holders, holding constant other characteristics. Mobile money has a positive and significant impact on saving for daily consumption, for protection against income shocks, and for business and education investments. In addition, I find that mobile money is a complement to formal savings (bank accounts) and a substitute for informal savings. By increasing saving, mobile money better enables individuals to rely on savings in the event of a negative income shock. These results are consistent with a policy agenda that promotes financial inclusion by increasing access to mobile technologies. / Thesis (BA) — Boston College, 2017. / Submitted to: Boston College.

Impact of political institutions on electricity generation outcomes in Sub-Saharan Africa

Ngwane, Zamangwane Beryl 02 September 2015 (has links)
A Research Report Submitted to the Faculty of Humanities In partial fulfillment of the requirements for obtaining the degree of Master of Arts in International Relations / Africa’s wave of democratisation since 1990 has transformed political institutions in the region. But while democracy is a desirable end in itself, considerable doubts remain about whether it is contributing to better development outcomes. This study investigates the impact of political constraints on electricity generating capacity, using cross-national data for 46 sub-Saharan African countries. It tests the hypothesis that institutions that restrain arbitrary executive authority result in higher levels of electricity generating capacity. The hypothesis is informed by the theory of credible commitment. This theory holds that political constraints provide a stable political and policy environment that reduces temptations for governments to renege on their commitments. Credible commitments are especially important in attracting investment with a long gestation period, such as investment in electricity generating capacity. In my method I use a combination of statistical analysis and nested case studies to probe the congruence of these outcomes with my hypothesis. For the nested analysis I use the statistically chosen countries of Rwanda and Kenya, which in themselves conform to the pattern of the hypothesis. My central finding is that the presence of democratic political institutions has led to improved electricity generating outcomes in African states. In this way the study contributes to the understanding of the developmental consequences of democratisation in Africa.

Essays on development and biodiversity conservation in Sub-Saharan Africa / Essais sur le développement et la conservation de la biodiversité en Afrique sub-saharienne

Amin, Ariane Manuela 03 December 2014 (has links)
La présente thèse est composée d’un ensemble de travaux de recherche en économie appliquée qui s’inscrivent dans le champ contemporain de l’économie de la biodiversité. La thèse s’intéresse spécifiquement aux liens entre développement économique, bien-être local et conservation de la biodiversité avec comme zone d’étude l’Afrique subsaharienne. Un chapitre introductif présente les questions de recherche débattues dans cette thèse et situe notre contribution dans la littérature.Le reste de la thèse est composé de deux parties regroupées en études macroéconomiques et en études de terrain. La partie 1 (composé du chapitre 2 et du chapitre 3) aborde le lien biodiversité-développement sous un angle macroéconomique en considérant les interactions spatiales entre pays. Le chapitre 2 examine l’impact du développement en Afrique Subsaharienne sur la biodiversité mesuré à partir d’indicateurs récents sur les espèces menacés. Le chapitre 3 s’intéresse aux mécanismes qui soutiennent les politiques publiques de conservation en Afrique Subsaharienne et teste l’effet du tourisme, de l’aide environnementale et des effets transfrontaliers sur l’effort de conservation. La partie 2 (composé du chapitre 4 et du chapitre 5) présente deux études de cas en Côte d’Ivoire. Le chapitre 4 évalue monétairement les coûts et les bénéfices de la conservation pour les populations locales. Le chapitre 5 examine les préférences des populations pour la conservation et identifie les facteurs clés qui déterminent ces préférences locales. Le chapitre 6 fait une synthèse des résultats en tire les implications en termes de recommandations de politiques et présente de potentielles extensions de la thèse. / This thesis is composed of a set of research in applied economics that enroll in the contemporary field of economics of biodiversity. The thesis focuses specifically on the links between economic development, local welfare and biodiversity conservation in sub-Saharan Africa region. An introductory chapter presents the subject of the thesis as well as the research field and situates our contribution.The rest of the thesis is composed of two parts divided into macroeconomic studies and case studies. Part 1 (composed of chapter 2 and chapter 3) addresses the link biodiversity and development under a macroeconomic perspective by taking into account spatial interactions between countries. In chapter 2, we examine the impact of development in sub-Saharan Africa on biodiversity using recent indicators on threatened species. In chapter 3, we focus on the mechanisms that support public conservation policies in Sub-Saharan Africa and tested the effect of tourism, environmental aid and spillover effects on conservation effort. Part 2 (composed of chapter 4 and chapter 5) presents two case studies in Ivory Coast. Chapter 4 presents a cost benefit analysis using contingent valuation and market price method. It evaluates the costs and benefits of conservation for local populations. In chapter 5 we examine people's preferences for conservation and identify key factors that determine local preferences. In the last chapter we draw implications of results and present potential extensions of this thesis.

Enforcement of copyright in the music industry : a critical analysis of the legal and institutional framework on enforcement in Sub Saharan Africa

Ouma, Marisella Nabongo January 2010 (has links)
It is trite to state that law without effective enforcement is of no use to those it seeks to protect. Nevertheless, it must be emphasised that for a law to be effective, there have to be corresponding institutional structures. Enforcement of copyright involves two phases. The first is formulation and enactment of law. The second phase is the implementation of legal provisions that includes interpretation of law and determination of cases by the courts, investigation of copyright violations, prevention of unauthorised exploitation of the rights and the use of sanctions and remedies provided by law. The main problem for rights holders is not so much in written law but in enforcement or lack thereof. Some creative industries in sub Saharan Africa are being threatened due to unauthorised commercial exploitation of copyright protected works. This is despite strengthening of national laws in the region. There are various reasons for the impending demise of such industries, but the crucial factor is lack of or limited enforcement. The thesis looks at the important issue of enforcement from the perspective of the music industry in sub Saharan Africa. Based on an analysis of four sub Saharan countries, namely Kenya, Nigeria, Senegal and South Africa, this thesis illustrates that despite having in place relatively modem copyright laws, these countries still experience high levels of unauthorised commercial use in respect of music. The thesis suggests that a key factor that promotes unauthorised commercial use is lack of effective enforcement." Through a critical analysis, based on the political, social, economic and technological perspectives, the thesis addresses three questions. First, why is copyright enforcement a problem in sub Saharan Africa? Secondly, why has the existing legal regime failed to ensure effective enforcement? Thirdly, what is an effective copyright enforcement regime? Effective enforcement of copyright, from a political, economic, social and technological perspective involves the existence of enforceable law, as well as effective enforcement mechanisms in both private and public sectors. An effective enforcement regime ensures conformity to law, involves a constant review of existing legal regimes and institutional structures (such as enforcement agencies) as well as adoption of new procedures and technologies to reduce incidences of non-compliance. The thesis concludes by suggesting proposals for policy guidelines on enforcement of music copyright in sub Saharan Africa.

The dynamic response process to conflicting institutional demands in MNC subsidiaries - An inductive study in the Sub-Saharan African e-commerce sector

Holm, Alison E., Decreton, Benoit, Nell, Phillip C., Klopf, Patricia January 2017 (has links) (PDF)
In this paper, we examine responses to the conflicting institutional demands faced by an e-commerce subsidiary located in Sub-Saharan Africa and headquartered in Europe. Following an inductive approach, we gathered data from a 6-month participant-observation study and interviews with local managers. Our findings show that the subsidiary managers responded to conflicting institutional demands in a dynamic way, taking one response after the other. In some cases, the subsidiary managers responded in a way that they thought would be satisfactory but subsequent pressures from their headquarters or their local environment pushed them to adopt a new response. In other cases, the subsidiary managers intentionally adopted responses knowing that they would (have to) adopt another response later in the process.

Alleviating Poverty in Sub-Saharan Africa

dubeck, owen 01 January 2019 (has links)
While most of the world has been able to dramatically reduce extreme poverty rates, Sub-Saharan Africa has failed to do so and is the only region in the world with more people living in extreme poverty than thirty years ago. This thesis will develop a policy framework for alleviating poverty by drawing from countries that are performing surprisingly well and poorly in the region. The thesis concludes with an analysis of whether education, health, or agricultural sectors should be receiving more or less funding based on expected rates of return and the feasibility of policy successes.

Sacred Dictators: A Wholly Unholy Relationship between Dictatorships and Religious Leaders

McQuaid, Thomas 20 December 2018 (has links)
How a single party and personal dictatorship survive has been a question of much debate among scholars. Geddes (1999, 2003) creates a model to determine which survives the longest. Within her model, she finds that a single party dictatorship – one with a party apparatus – survives longer than a personal dictatorship – one where a single person has sole policymaking ability. She argues that the fundamental difference between the two is how each treats the opposition. The party apparatus allows a single party dictatorship the means to silence the opposition by coopting it into the party structure whereas a personal dictatorship must rely on the wealthy and military to keep any opposition at bay. With a single party dictatorship being able to coalesce the opposition, this dictatorship is more stable and survives longer. I agree with Geddes’ reasoning and seek to clarify how this situation works in Sub-Saharan Africa. I argue that a single party dictatorship can silence and use religious leaders in the opposition to gain support from the religious leaders’ followers. This additional support from the religious leaders and the followers makes single party dictatorships survive longer than personal dictatorships in Sub-Saharan Africa. In this research, I explain the importance of religion as a variable for dictatorship survival research in Sub-Saharan Africa. I show that religious leaders have a certain level of control over followers and if coopted by a dictatorship, religious leaders’ control garners support among followers. I further explain how religious leaders are in the opposition and therefore can only be coopted by a single party dictatorship. I conclude by showing that religious leaders increase a single party dictatorship’s survival likelihood.

Evaluation and comparison of current legal and regulatory framework for traditional medicines in five selected African countries: A move towards harmonization of regulation of traditional medicines in Africa.

Chikwari, John Ratiso January 2019 (has links)
Masters of Science / Background: In Africa, traditional medicine (TM) practice has been in existence since time immemorial as the major source of pharmacotherapy. However, unlike orthodox medicines TM policies and regulations are not formalised let alone standardised. African nations have different approaches and regulatory requirements whereas in some states policies are even non-existent. Aim: The aim of the mini thesis was to assess the current policies and guidelines for regulation of TM in five selected sub-Saharan African countries relative to the WHO recommendations on traditional medicine policy. Method: The mini thesis was a desk review of current policy frameworks and guidelines for regulation of traditional medicines relative to WHO recommendations on TM policy in sub- Saharan Africa using five selected countries. Result: The results from the five selected countries showed significant difference in the current policies and guidelines on the regulation of TM, but no significant difference in the actual WHO TM policy indicators that the countries implemented. Discussion: Regularisation of TM practice by integrating it into main health systems could make it more acceptable. The complexity of TM/herbal products needs a different yet integrated approach. Harmonisation of regulatory requirements eliminates the need for redundant testing, ensures consistency across regions and improves implementation of WHO TM policy indicators.
