The purpose of this paper is to investigate the correlation between income inequality and economic growth in a cross-section of 90 countries from 2002 to 2006. The controversial Kuznets Hypothesis, the economic model that hypothesizes the relationship between inequality and per capita income is an inverted U-shaped curve, is scrutinized and investigated to consider its viability and accuracy. A multiple linear regression model is estimated and the viability of the regression model is supported by several statistical tests. Based on the estimated model, a negative correlation between growth and inequality has been found.

Past research has established that South Africa has a problem of high unemployment rate. This is accompanied by a low entrepreneurship activity that tends to lag far behind that of other developing countries as measured over the years by the Global Entrepreneurship Monitor (GEM) research. Entrepreneurship and small business are well recognised for their role in both economic growth and job creation. This study set out to investigate the informal sector entrepreneurial activity in Emfuleni Local Municipality which has experienced large scale retrenchments over the past decade. A literature survey was conducted to understand the characteristics, successful practices and weaknesses that distinguish the informal sector from the formal sector. The empirical study which was conducted by means of survey questionnaire among the informal sector entrepreneurs indicated that entrepreneurship in the informal sector can provide a form of income for some people that cannot be absorbed in the formal labour market. The findings of the study was that this area of entrepreneurship is dominated by the youth as more than half of the respondents were below the age of 35 years. It was also found that most of the entrepreneurs have never been formally employed which may be problematic when it comes to skills. While most of them recognised the importance of training and skills, they were also positive that they can benefit from training especially in the area of marketing and promoting their product and services. These entrepreneurs however do not seem to be benefiting from government initiatives such as the workshops offered by the local municipality and other assistance offered by the government agencies. The low skills level of most of these entrepreneurs may also hinder their ability to grow their businesses beyond the one–man operations. It is recommended therefore that the organisations such as the National Youth Development Agency double their efforts in helping the youth to become successful small business owners. The government agencies, particularly those targeting the youth should make a conceited effort to provide training in particular to these people if they are to make a lasting impact on job creation. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2011.

The country is currently experiencing a tight electricity schedule. The demand for greater capacity than the country can supply is a reality. Raising unemployment and poverty levels are a situation we contend with daily. The aim of the study is to create a generic framework for right–sourcing in the electricity supply industry. The various phases of strategy creation were analysed to achieve this target. The process of identifying core business processes was discussed. Strategic alignment is important for the success of the Information Technology strategy; this study discussed how this could be accomplished. The various Information Technology sourcing strategies were examined. The probability of a process being outsourced, stemmed from the simplicity and repetitiveness of a transaction or process, and costs involved. An empirical study was done with both quantitative and qualitative analysis. The study looked at Contract Management, Information Technology Strategy and Benchmarking. A comprehensive right–sourcing framework was developed to assist in making the correct decisions. This framework could guide new entrants to the ESI in helping them shape their strategy and formulate a distinct competitive advantage. It could assist them in meeting the growing capacity demands faster and making a significant positive contribution to the economy. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2012.

In 1995, Jeffrey Sachs and Andrew Warner found a negative relationship between natural resources and economic growth, and claimed that natural resource abundance is a curse. The work of Sachs and Warner has been widely cited, and many economists now accept the curse of natural resources as a proven phenomenon (e.g. Papyrakis and Gerlagh, 2004; Kronenberg, 2004). In this thesis, I provide a new framework for evaluating this claim. I begin by providing a summary of the related literature and discussion of possible explanations for the curse. This summary is followed by a critical assessment of the theory underlying previous research. Next, I develop a new model for evaluating the curse of natural resources. I find that natural resource abundance does not directly impact economic development. However, petroleum resources are associated with rent-seeking behaviour that can negatively influence economic development. Finally, I show that my results are robust to various sensitivity analyses. The results from my model provide a deeper understanding of how natural resource abundance affects economic outcomes.

Economists have studied the relationship between population growth and economic growth for a very long time and not found any clear relationships. Recently they have begun to focus on the factors of population growth such as fertility and mortality rates. From this line of study came the age-structure hypothesis. The age-structure hypothesis was founded on the evidence from Asia’s very successful demographic transition and many economists are now wondering whether Sub-Saharan Africa (SSA) will be able to repeat this feat. Hence, this study aims to investigate the relationship between the dependency ratio (a ratio between the dependents (ages 0-14 and 65+) and the number of workers (aged 15-64) in a population (Eastwood and Lipton, 2012)) and economic growth in SSA and search for evidence of a demographic dividend. Not many previous studies have been done focusing completely on SSA and this study therefore aims to shed some light on the subject. The investigation was done by a cross-sectional regression analysis using a sample of 26 sub-Saharan countries and secondary data from mostly the World Bank. The results show a significant relationship between both versions of the dependency ratio and economic growth but do not show evidence of a demographic dividend. Out of the two versions of the age-structure hypothesis, most support was found for the strong version. Furthermore, support was found for the conditional convergence theory and both savings per capita and the initial level of education were found significant. However, the results had problems with severe multicollinearity and it was concluded that the results were not entirely reliable and should not be depended upon.

Economic growth is a goal for countries around the world in order to improve living standards, and the effect of foreign direct investments (FDI) has long been studied. There are today many theories and empirical studies regarding FDI. Many questions being studied but finding a straight answer to these have showed to be anything but easy. The results and conclusions go in different directions and much disagreement on whether or not FDI actually contributes to growth. One of the core triggers to the Chinese high economic growth pattern is attributed to FDI, this thesis investigates the same FDI impact on economic growth but with focus on sub-Sahara Africa. With the help of different theories and empirical studies we have selected our variables believing they will have a significant impact on this question. With the data collected from the World Bank database about the countries and seven different variables, a regression is created. The results show that FDI plays a part when it comes to GDP per-capita growth and also that corruption has a significant negative effect on growth rates. FDI in sub-Saharan Africa is hypothesized to mainly consist of brownfield investments as a potential explanation. The data this study uses is between 2005 and 2013, meaning the results are probably not applicable to be interpreted long-term.

This doctoral thesis contains three essays on the economics of climate change and the electricity sector. The first essay deals with the subject of greenhouse gas (GHG) emissions and economic growth. The second essay addresses the issues of climate change policies, especially the role of the emergent innovative technologies, and the restructuring of the electricity sector. The third essay presents a model of transmission investments in electric power networks. Chapter One studies the impacts of climate change on economic growth in the world economies. The paper contains explicit formalization of the depletion process of exhaustible fossil fuels and the phase of technology substitution. The impacts of climate change on capital flows and welfare across countries are also investigated. The restructuring of the electricity sector is studied in Chapter Two. It also analyzes how climate change policies can benefit from emergent innovative technologies and how emergent innovative technologies can lower GHG emissions. It is shown that the price of electricity is strictly rising before emergent innovative firms with zero GHG emissions enter the market, but strictly declining as the entry begins. In Chapter Three, a model of electricity transmission investments from the perspective of the regulatory approach is formulated. The Mid-West region of Western Australia, a sub-system of the South West Interconnected System is considered. In contrast with most models in the literature that deal only with network deepening, this model deals with both network deepening and network widening. Moreover, unlike the conventional investment models which are static and deal only with the long run, this model is dynamic and focuses on the timing of the infrastructure investments. The paper is a study of an optimal transmission investment program which is part of the optimal investment program for an integrated model in which investments in transmission and investments in generation are made at the same time.

In existing economic literature on finance and economy, it is argued and generally accepted that financial intermediation contributes to economic growth though the contending argument is that financial development is simply a result of economic growth. However, studies on the contribution of financial intermediation of nonbanks (as opposed to banks) to economic growth are relatively scant and too general to clarify the mechanism through which nonbank financial intermediation might help economy to expand and develop. The focus of this study is on whether nonbank financial intermediation contributed to economic growth in the case of Korea where the share of nonbank financial intermediation increased from around 20% in 1970 to more than 60% in the early 1990's. This study is particularly interesting in light of the fact that rapid economic growth in Korea was accompanied by a concomitant increase in the share of nonbank financial intermediation. As a precursor to the empirical analysis, this study shows theoretically that financial intermediation of nonbanks subject to lesser liquidity control is complementary to, rather substitutional for, that of banks. Further, it is shown by optimizing a two-period dynamic model that under certain conditions nonbank intermediation increases an economy's savings mobilization and contributes to the economic growth. For empirical analysis, we used the annual data from 1972 to 1994 which can be considered as a financially repressed period. The empirical results are all consistent with the theoretically expected: nonbanks are complementary to banks in financial intermediation, increased the savings mobilization, and in the end contributed to the economic growth of the Korean economy during the sample period. Further, the estimated allocative efficiencies of nonbanks are almost in phase with business cycles, which may well be interpreted as consistent with the proposition that nonbanks financial intermediation made a significant contribution to Korea's economic growth.
