- Description: It is the purpose of this study to examine the interplay of supply and demand factors for the South African economy, and to relate this to the functional, personal, and racial distribution of incomes. On the one hand, it appears that a concentration of incomes in the hands of those who possess both the ability and willingness to save, and to utilize the savings for productive investments, is a crucial determinant for the enhancement of economic growth. On the other hand, an excessive income concentration may severely limit the purchasing power of the major part of the population, thus inhibiting domestic investment. The study is developed, partly in terms of a theory of economic development, and partly in terms of a theory of economic growth. The analysis covers the period from 1918 to the present time. Periods during which the actual economic growth would have been faster had the distribution of incomes favoured work income receivers at the expense of other income receivers, are identified by employing a short-term post-Keynesian model of functional income distribution. Periods during which an acceleration of economic growth would have been achieved had the opposite condition prevailed, are also shown. An analysis is made both of the division by race of aggregate income, and of racial wage differentials in particular economic sectors. A noticeable identity between the economic growth performance and racial wage differentials is evidenced both for the mining and manufacturing sectors. It appears that in the long-term, there is regularity in respect of correlations between measures of the inequality in the size distribution of income on the one hand, and the rates of investment and economic growth on the other. From this observation, it becomes evident that inequality in the distribution of personal income has been a necessary condition for the attainment of economic growth in South Africa. It is obvious that a study of this sort necessitates the use of much statistical data. In order to avoid major disturbances in the flow of the theoretical and analytical arguments through the discussion of the statistical material, the work is submitted in two volumes, viz.,Volume 1 dealing with the Theory and Analysis, and Volume II with the Statistical Foundations.

- Description: Emotional Intelligence and Leadership are two very important constructs to organizations. Likewise concepts like OCB, conflict handling and intention to quit of employees are equally important constructs to organizations. The primary aim of the present study was to determine how well Organisational Citizenship Behaviour and intention to quit as well as the conflict handling style of subordinates could be predicted by means of leadership style, and the emotional intelligence of leaders. A secondary aim was to determine whether a causal model could be built to represent the relationships among the variables included in the study. Relationships among these constructs were investigated in a South African sample of employees (N=470) working for various organisations. The construct validity and internal consistency of the measuring instruments were investigated. The finally accepted factor structure of not one of the measuring instruments matched the original structure as found by the authors/developers of the measuring instruments. It was therefore decided that in all cases the factor pattern as determined on the responses of the present sample would be used in further analyses of the data. Emotional intelligence of leaders as seen by subordinates and the self - perceived conflict handling styles of subordinates seem to be related in the case of Integrating and Obliging conflict handling styles and both the emotional intelligence sub-scales, i.e. Motivation and Vigilance. The Multiple Regression analysis indicated that the emotional intelligence sub-scales scores played a minor role in the prediction of Organizational Citizenship Behaviour. Models of the relationships among the variables were built by studying the results of v previous as well as the present study. The model, in which emotional intelligence is depicted as a causal variable influencing - through leadership behaviour – organizational citizenship behaviour and the integrating style of handling interpersonal conflict represented a good fit with the data. These results seem to provide some structure for thinking about the relationships among the variables and can possibly serve as frames of reference in future studies.

- Description: This research deals with socially responsible investing (SRI) in its broadest context in South Africa and includes an analysis of the risk-adjusted performance of local SRI funds. SRI refers to an investment strategy whereby investors integrate moral as well as environmental, social and governance (ESG) considerations alongside conventional financial criteria in evaluating investment opportunities. Typical SRI strategies include screening, shareholder activism and cause-based (targeted) investing. The primary objective of this research was to obtain a deeper understanding of SRI in South Africa as it represents a powerful means whereby private sector capital can be channelled into areas of national priority. Data and methodological triangulation strategies were adopted to investigate the research problem, respond to the research questions and test the research hypotheses of this study. The phenomenological component of the research consisted of an extensive literature review as well as in-depth, face-to-face interviews conducted with twelve SRI fund managers and industry experts. The positivistic dimension of this research centred on the construction of the first complete database of SRI funds in South Africa, the sourcing of quantitative primary data and the testing of eight pairs of null and alternative hypotheses. Risk-adjusted performance was evaluated by means of the Sharpe, Sortino and Upside-potential ratios during three sub-periods, namely 1 June 1992 to 31 August 1998, 1 September 1998 to 31 March 2002 and 1 April 2002 to 31 March 2006. Forty-three SRI funds have been launched in South Africa since June 1992 and it is estimated that SRIs constitute approximately 0.7 percent of the total investment capacity in the country. It was found that most local SRI funds combine a cause-based investment strategy with a positive or best-of-sector screening approach. ESG screens were found to focus on the promotion of broad-based Black Economic Empowerment and the development of social infrastructure in South Africa. The FTSE/JSE SRI Index and the Financial Sector Charter were identified as the most prominent drivers of SRI in South Africa, whereas a lack of skills and a shortage of new SRI opportunities, asset classes and funds were seen as impediments to the growth of the local SRI sector. The empirical evidence shows that: - local SRI funds underperformed relative to their respective benchmark indices during the first two sub-periods but significantly outperformed them during sub-period three (the resurgence period of SRI in South Africa); - local SRI fund performance is not significantly different from that of a matched sample of conventional (non-SRI) funds; and - local SRI funds significantly underperformed relative to the general equity market in South Africa during sub-period two (the decline period of SRI in South Africa) but performed on a par with the FTSE/JSE All Share Index during sub-periods one and two. The findings of this research therefore suggest that investors can consider SRI funds as part of a well-diversified investment strategy. It is strongly recommended that a Social Investment Forum be established in South Africa to address the educational needs of stakeholders in the local SRI sector. It is also recommended that local asset managers adopt a focused differentiation strategy to take advantage of the growing SRI sector in South Africa.

- Description: Given the predicted increase in the number of family businesses owned and/or managed by siblings (Sibling Partnerships), as well as the lack of understanding and research attention given to such sibling teams, the purpose of this study was to contribute to the more effective functioning of such family businesses in South Africa by identifying the factors that impact on their success. With this purpose in mind, the primary objective was to identify, investigate and empirically test the possible influences of, and relationships between, various factors and the Perceived success of Sibling Partnerships. This study sets out to integrate prior findings and theories on team effectiveness and family relationships, to find support for these theories in the family business literature, and to incorporate these findings into a comprehensive model. The literature study revealed 5 main categories (context, composition, structure, processes, and people) of constructs influencing the Perceived success of sibling teams. Within these 5 main constructs, 13 underlying independent variables were identified and hypothesised to influence measures of effectiveness of sibling teams, namely the dependent variable Perceived success, and the 2 intermediate variables Financial performance and Family harmony. Of the 13 underlying independent variables, 6 were categorised as task-based and 7 as relational-based factors. In addition, hypotheses were formulated for possible relationships between the various task-based constructs (context, composition and structure) and the processes and people constructs. Each construct was clearly defined and then operationalised. Operationalisation was done by using reliable and valid items sourced from tested measuring instruments used in previous studies, as well as several self-generated items based on secondary sources. A structured questionnaire was made available to respondents identified by means of the convenience snowball sampling technique, and the data collected from 371 usable questionnaires was subjected to various statistical analyses. An exploratory factor analysis was conducted, and Cronbach-alpha coefficients were calculated to confirm the validity and reliability of the measuring instrument. The 6 task-based latent variables were confirmed by the exploratory factor analysis. However, all the other latent variables, as originally intended in the theoretical model, could not be confirmed. Instead, 3 dependent variables were identified, namely Financial performance, Growth performance and Satisfaction with work and family relationships, and 6 relational-based constructs, with some changes, did emerge. Structural Equation Modelling (SEM) was the main statistical procedure used to test the significance of the relationships hypothesised between the various independent and dependent variables. Because of sample size restrictions the conceptual model could not be subjected to SEM as a whole; consequently 10 submodels were identified and subjected to further analysis. The following independent variables were identified as influencing the dependent variables in this study: • Internal context • Complementary skills • Leadership • Shared dream • Fairness • Sibling relationship • Non-family members • No other family members (spouses and non-active siblings) In addition, the factors Complementary skills, Leadership, Past parent involvement, No present parent involvement, and No other family members, were identified as significantly influencing the relationship between the siblings involved in the Sibling Partnership. Furthermore, an Analysis of Variance (ANOVA), Multiple Linear Regression analysis and t-tests were undertaken to determine the influence of demographic variables on the dependent variables. How ownership is shared in a family business involving siblings, the shareholding between the siblings themselves, and the nature of leadership between the siblings, has been found to influence the iv dependent variables in the present study. In addition, a Sibling Partnership is likely to perform most effectively when it is composed of a relatively young sibling team that has a small age gap between the members, and business performance will improve as the siblings gain work experience together, and as the number of employees increase. This study has added to the empirical body of family business research by investigating a particularly limited segment of the literature, namely Sibling Partnerships in family businesses. By identifying and developing various models that outline the most significant factors that influence the success of such family business partnerships, this study offers recommendations and suggestions for managing family businesses involving siblings, in such a way as to enrich their family relationships and to improve the financial performance of their businesses.

- Description: Standard practice dictates that mobile telephone service providers remain accurately aligned with the dynamic expectations structure of the target mobile telephone service users they serve. To comply with this requirement, literature sources assert that service providers need to adopt a candid marketing research orientation to understand what the users expect and in-build it in their service designs. Theory further contends that if such a business stance is diligently applied, any service provider is bound to gain a competitive edge in the market place. Notwithstanding the aforementioned, service providers continue design services without sufficient understanding of what users expect. This mindset has led to disparities in both the designed and the recieved service. Despite the pioneering works of earlier reserachers on the Gaps model, evidence shows that no research had been carried out to measure users' and providers' service quality perceptions in the mobile telephone branch of industry in Uganda. Much remains unknown as regards users' perceptions of expected and actual service quality and any potential disparity thereof. In the same spirit, much remains unknown as regards providers' perceptions of users' expectations and users' real expectations and potential disparity thereof. In order to measure the aforementioned disparities, the Gaps model was used in which Gaps 1 and 5 were measured for providers and users of mobile telephone services in the branch industry in Uganda.

- Description: Women remain notably underrepresented in management and leadership positions despite the enactment of Equal Opportunity and Affirmative Action policies. A critical literature review yielded evidence of a multitude of barriers inhibiting women’s career advancement beyond an apparent glass ceiling, but not which of the factors constitute the major barriers. A knowledge gap was further identified in research pertaining to characteristics of successful professional women and the environments that enable them to succeed in their professions. The purpose of the current study is to expand the empirical body of research and knowledge on factors contributing to the success of professional women, and of factors inhibiting the career progression of women in business. The study extends that of Punnett, Duffy, Fox, Gregory, Lituchy, Monserrat, Olivas-Luján and Santos (2006) and of Duffy, Fox, Punnett, Gregory, Lituchy, Monserrat, Olivas-Luján, Santos and Miller (2006), conducted in the Americas, to the South African context. The study suggests a conceptual framework for investigating factors that influence professional success of women. The developed conceptual framework of factors perceived to influence professional success was employed to empirically test the relationships between the variables presented. The empirical data collected was subjected to a series of statistical tests and the results considered in testing the hypotheses. Statistica 10 was employed to analyse the empirical data collected. Univariate and multivariate tests (MANOVA) were employed to determine whether sufficient evidence existed to make conclusions about hypotheses one to five of the study, relating to differences between two success groups of women based on their demographics and the selected variables. Pearson Product Moment Correlation (Pearson r) was employed to determine whether sufficient evidence existed to make conclusions about vi hypotheses six to ten, relating to significant relationships between the selected independent variables for the study and the professional success of women. Professional success was measured as job seniority level. For the pipeline success group, professional success was measured as seniority in relation to years in the employment sector and age. The contribution of the study to management science and possible limitations are discussed and recommendations made for future research. Recommendations for the development of women and for the social transformation of organisations are made. The study identifies a number of internal organisational support factors and government interventions which are recommended for inclusion in development initiatives for the achievement of gender equity.

The developed conceptual framework of factors perceived to influence professional success was employed to empirically test the relationships between the variables presented. The empirical data collected was subjected to a series of statistical tests and the results considered in testing the hypotheses. Statistica 10 was employed to analyse the empirical data collected. Univariate and multivariate tests (MANOVA) were employed to determine whether sufficient evidence existed to make conclusions about hypotheses one to five of the study, relating to differences between two success groups of women based on their demographics and the selected variables. Pearson Product Moment Correlation (Pearson r) was employed to determine whether sufficient evidence existed to make conclusions about vi hypotheses six to ten, relating to significant relationships between the selected independent variables for the study and the professional success of women. Professional success was measured as job seniority level. For the pipeline success group, professional success was measured as seniority in relation to years in the employment sector and age. The contribution of the study to management science and possible limitations are discussed and recommendations made for future research. Recommendations for the development of women and for the social transformation of organisations are made. The study identifies a number of internal organisational support factors and government interventions which are recommended for inclusion in development initiatives for the achievement of gender equity.

Money attitudes and materialism among generation Y South Africans: a life-course study

- Description: Materialism has long been a subject of interest to researchers. More negative than positive consequences have been reported from studies on the lifestyles of materialists. For example, increased consumer and credit card debt, shrinking saving rates, increased number of consumers filing for bankruptcy, lower levels of life satisfaction and the depletion of natural resources are reported to be emanating from the increasing levels of materialism in societies. It is thus important to investigate the factors that can be implicated for the growth of materialism. Most of the studies attempt to explain materialism at a given point in time in isolation of the events people have experienced in their early life or childhood. Realizing that this practice is a shortcoming in consumer research, there is a call that consumer behaviour, such as materialism, be studied as a function of past life experiences using the life-course approach. While few studies have applied this approach to understanding materialism, little is known about the psychological processes that link childhood family structure to materialism. It is against this background that this study used the life-course approach to study how childhood family structure affects materialism through psychological processes of perceived family resources (tangible and intangible), perceived stress from the disruptive family events, and money attitudes of Generation Y South Africans. The study also assessed the moderating role of money attitudes on the relationship between childhood family experiences and materialism. Money attitude dimensions of status, achievement, worry, security and budget were introduced to broaden the life-course study of materialism because they are reported to begin in childhood, to remain in adulthood and they function in the background of every behavioural intention and action. Generation Y (commonly reported to be born between 1977 and 1994) were the subject of this study, because the literature reviewed revealed that these emerging consumers are not only numerous (about 30 percent of South Africans are Generation Y), have considerable influence and spending power, but most have been raised in disrupted single-parent/income families. With reports from family sociologists on the outcomes of divorce and single-parenthood (for example, stress, inadequate family resources, and low self-esteem) questions were raised as to how these outcomes would affect Generation Y money attitudes and materialistic values. Ten hypotheses were formulated to empirically answer the research questions. Using quantitative methodologies based on the nature of the research questions and problems, data were collected through online questionnaire from 826 business undergraduate students from the Nelson Mandela Metropolitan and Western Cape Universities. University-aged respondents were appropriate for this study since they are ideally suited to remember their past family circumstances and must have already formed consumption habits, attitudes and values at their age. The first research problem was to evaluate how two of the life-course theoretical perspectives (i.e., family resources and stress) selected for this study would explain the materialistic values of Generation Y South Africans raised in non-intact (did not live with both biological parents before 18th birthday) and intact (lived with both biological parents before 18th birthday) family structures through the money attitudes adopted. The results showed that even though a significant difference in perceived family resources (both tangible and intangible) and stress was found between subjects raised in non-intact (or disrupted) and intact families, the difference in materialism as a whole was not significant. In terms of the three materialistic values of success, happiness and centrality, subjects raised in disrupted families significantly scored higher in the happiness dimension. For the money attitude dimensions of status, achievement, worry, budget and security they significantly scored higher in the worry money attitude. Results of the correlation analyses showed that perceived decrease in tangible (food, clothing and pocket money) family resources was a childhood factor that affected later worry money attitude to significantly and positively influence all of the three materialistic values. Perceived decreases in intangible family resources (for example, love and emotional support) negatively affected the symbolic money attitudes of status and worry, which in turn, positively affected only the happiness dimension of materialism. Perceived increase in stress positively affected all of the symbolic money attitudes of status, worry and achievement. These, in turn, positively influenced only the success and happiness materialistic values. The second research problem was based on an assessment of the moderating role of money attitudes on the childhood family experiences to materialism relationship. Using hierarchical regression analyses, it was found that only the achievement and worry money attitude dimensions moderated the family resources to materialism relationship. This means that when subjects hold higher worry and achievement money attitudes, an increase in family resources (tangible and intangible) will have less effect in reducing materialistic tendencies. For the stress to materialism relationship, only the worry money attitude dimension had a moderating effect, meaning that when higher worry money attitude is held, an increase in stress from family disruptions would have a greater effect in increasing materialistic tendencies. None of the five money attitude dimensions did, however, moderate the childhood family structure to materialism relationship. The results of this study do not only have theoretical implications, but also provide valuable information to consumer-interest groups, banks and retailers, especially in terms of the money attitudes of Generation Y consumers in South Africa.

- Description: Despite decades of gender research and public action by civil society, policy makers continue to neglect the role of women as breadwinners who work at improving the socio-economic conditions in rural areas such as Wooldridge, a traditional rural village in the Amathole district of the Eastern Cape Province. The apartheid system created an environment that continues to perpetuate both poverty and gender inequality in rural areas. Hence, rural women in Wooldridge still experience poverty, despite welfare benefits. They are located in a poverty-stricken area without basic infrastructure and with little or no access to economic assets. They use primitive methods and indigenous knowledge to develop survival strategies. This study argues that unemployed rural women in Wooldridge cannot survive without assistance from government. Indigenous knowledge and agricultural as well as non-agricultural activities are critical to household livelihoods in Wooldridge. These activities are an important route through which these rural women can escape poverty. The primary objective of this research was to obtain a better understanding of how unemployed rural women survive in Wooldridge. Furthermore, the necessary conditions required to sustain livelihood in the rural areas were identified. This was mainly done to help alleviate the plight of rural women in Wooldridge and to improve the quality of life of the rural population. The aim is to generate a policy response to rural women that is economically development-oriented. The study was based on five research objectives. The first objective was to identify the survival strategies of unemployed rural women in Wooldridge; the second to ascertain what can be done to alleviate the plight of rural women in Wooldridge. The third objective was to ascertain what has been v done to address the needs of rural women in the Wooldridge area by actors of development, such as government and non-governmental organisations. The fourth objective was to identify the constraints faced by unemployed rural women in Wooldridge in achieving food security and generating income, with the last objective to make recommendations regarding policies that can enhance rural economic development and assist unemployed rural women to reduce poverty. The main finding in terms of the first research objective is that the survival strategies of unemployed rural women are welfare benefits, the selling of assets, remittances, handicraft production and vegetable gardens. In terms of the second research objective, the main finding is that investment in human capital through the empowerment of women will assist them in improving the quality of life of the Wooldridge community. Empowerment involves skills and training, education and access to basic services, expertise regarding credit, land, the growing of vegetables and income-generating projects. The main finding in terms of the third research objective is that the Peddie Women Support Centre that is located in the city centre of Ngqushwa does not have the capacity to reach out to rural areas. Rural women in Wooldridge have not received responses to their plights from government or from development practitioners. These actors of development play an important role in empowerment. In terms of the fourth research objective, the main finding is that structural constraints hinder the economic activity of rural women in Wooldridge. Government policy that encourages investment in infrastructure using labour-intensive methods will eliminate service backlogs in underserviced areas such as Wooldridge. The main finding in terms of the fifth research objective is to ascertain the impact that new legislation can have to ensure that rural women have the same access and entitlement to land and resources as women from urban areas. Furthermore, service-improvement programmes should be developed and micro-enterprises and agricultural and non-agricultural activities that will generate income and employment should be encouraged in order to reduce poverty in Wooldridge.

An estimate of the cost of electricity outages in Zimbabwe

- Description: This thesis estimates the cost of electricity outages in Zimbabwe for the year 2009. Much reference is made to government, the power utility - Zimbabwe Electricity Supply Authority (ZESA) and other countries in the Southern African Power Pool (SAPP), also experiencing electricity outages. An electricity outage is a complete loss of power supply to an area. An outage may result from planned or unplanned load shedding or faults. Load shedding is accelerated by power supply shortages. The shortages are experienced during peak demand times. In 2009, Zimbabwe’s peak demand was about 1574MW. ZESA had the capacity to supply 1080MW and imported 100MW (guaranteed from Mozambique), leaving a shortfall of 394MW. This shortfall is worsened by transmission losses (about 108MW) and consumption by ZESA properties (about 200MW) bringng down the supply to customers of about 700MW. The supply shortage is the result of a lack of investment in the power sector by government for expanded generation capacity, incorrect pricing, droughts, internal conflicts, skills flight, government energy sector regulation, vandalism of equipment and under supply of coal to thermal power stations. Consumers in all sectors are experiencing power outage incidences of different duration. The severity of the inconvenience depends on the load shedding time table, preferences of the power utility and arrangements that can be made with the utility. Power outages negatively affect (and result in cost to) the productive sectors (industry, mining and farming) and households. The main objective of the thesis is to estimate the cost of power outages to the sectors. Sub-objectives of the study include: to identify the main features of power crisis in Zimbabwe and government response to it with a regional power generated setting; to formulate a model that clearly identifies the different cost components of power outages in Zimbabwe; to identify appropriate methods by which to estimate these cost components; to estimate the cost of power outages to the productive sectors (mining, agriculture and industrial) and households of Zimbabwe; to critically analyse the credibility of these estimates, and to consider the saving of the costs of outages achieved through increased investment in generating capacity in Zimbabwe. ZESA undertook reforms (institutional and tariff) in order to improve management efficiencies and supply. It was divided into five entities resulting in management and financial improvement, but its reform of tariffs has been stiffled by subsidies and price regulations. ZESA adopted the cost plus rate of return pricing strategy in 2004 but regulation kept the tariff below cost. The regulation is pro-poor in aim but it encourages wasteful consumption. Similar supply shortages are affecting the whole SAPP group. The power pool load shed 758MW in 2009. In Zimbabwe alone load shedding was 315MW. In an attempt to solve the problem, member utilities engage in bilateral contacts and short-term trading through Short Term Energy Markets (STEM). A number of Southern African countries have to load shed - the average frequency being three to five (3-5) times per week for the region. A number of studies have been carried out by different scholars attempting to assess the impact and cost of outages. The general conclusion is that power outages cause significant costs to consumers, both direct and indirect. From a global perspective, the increase in the quality of electricity supplied has fallen behind the increase in quantity demanded, causing an increase of incidence in power outages. An analysis of Sub-Saharan Africa shows that the causes of supply shortages are natural (drought), oil price shocks, conflict and the lack of investment in generation capacity. This generates two outage cost estimates – a direct cost (welfare loss) and indirect cost (backup cost). The sum of these estimates is the total outage cost. The direct cost estimate is based on direct loss incurred during the power outages - lost production, lost materials, and lost time or leisure. In order to derive an estimated direct cost, it is necessary to obtain an accurate respondent self-assessment, which, in turn depends on the keeping of good records of hours of outages and losses incurred during outage times. The estimated indirect cost (backup cost) is derived from the cost of investment in backup sources and running of these sources as a mitigating measure during a power outage. The expected gain from self-generated kWh is assumed to be equal to the expected loss from the marginal kWh electricity not supplied by the utility (the outage). The annualised capital cost of backup source plus the variable cost of generating electricity by the backup source are another element of the cost of power outages. The prices of backup sources were obtained from the two leading retailers, Tendo Power and Ellis Electronics. To the extent that the captive generation includes investment in emergency or optional plant (as part of normal production infrastructure), it may overestimate cost.

- Description: Psychological capital (PsyCap), work engagement (WE) and organisational citizenship behaviour (OCB) are all positive constructs which research has indicated will have a positive impact on the bottom line. In light of Positive Organisational Behaviour, this has become increasingly important, particularly in the service industry where good service leads to satisfied customers and ultimately repeat purchases. This research took on the form of a cross- sectional design, using a composite questionnaire to measure PsyCap, WE and OCB. This was a self-report electronic questionnaire which was distributed via email to customer service representatives (N=276) from a national automotive company with dealerships in Gauteng and the Western Cape. The measurement models were revalidated for the South African sample of customer service representatives through conducting Exploratory Factor Analysis. PsyCap remained a four-factor structure, however lost items in the elimination process. Both the UWES and OCB instruments lost items and became two-factor structures. This makes the notion that these instruments are portable to the South African situation questionable. To confirm these structures, item parcelling was utilised and Confirmatory Factor Analysis was conducted. The results indicated that the new measurement models were better suited to the South African sample. Demographic groups had significant differences in the means for PsyCap, WE and OCB. Further to this, relationships between the constructs were tested through multiple regression and structural equation modeling. The most significant relationship was found between PsyCap and work engagement. Finally, PsyCap (barring optimism) and WE were found to load onto a single factor when testing for factorial independence, while OCB came out as a separate factor.

- Description: Grounded in the positive psychology paradigm the recently recognised core construct of psychological capital was focussed in a South African study. A non-experimental, correlational study (n=204) examined the relationship between authentic leadership, psychological capital, psychological climate, team commitment and intention to quit. The present study was exploratory in nature and the pattern of relationships being investigated had not been previously tested in a South African context. A self-administered composite questionnaire consisting of five psychological scales were distributed to employees in the junior to senior management level at a global tyre manufacturing organisation based in Port Elizabeth, South Africa. The five scales were the Authentic Leadership Questionnaire by Walumbwa, Psychological Capital Questionnaire by Luthans, Psychological Climate by Koys and DeCotiis, Team Commitment by Bennett and the Intention to Quit Scale by Cohen. All the measures applied on the South African sample were developed outside South Africa and model equivalence had to be established. The content and structure of the measures were investigated through confirmatory factor analysis and exploratory factor analysis. With the exception of the Cohen scale of intention to quit, all other measures changed their factorial structures to suit the present data. The propositions in the study were tested through descriptive statistics, t-tests, ANOVA, post hoc tests, Cohen’s d, Pearson product-moment correlation and multiple regressions. Structural equation models were built to test the relationships between the scales and sub scales of authentic leadership, psychological capital, psychological climate, team commitment and intention to quit. Results of the analyses carried out, show significantly strong relationships between the variables. Of note is the marked relationship between authentic leadership and psychological climate. Most of the propositions were accepted in light of the relationships that emerged. The proposition indicating structural equation models was rejected because none of the models built in the study successfully produced an adequate fit on the data. Contributions of the study were in terms of the portability of the measurement instruments applied in the study as well as the relationships that emerged. Re-validation of the measures is required to enable clarity on how the variables in the study are interpreted across cultural contexts. Directions for future research include extending the study to other samples and other cultures. Measuring social desirability of the instruments could possibly provide clarity on how the different samples respond to the measures. Studies that compare the reading ability as well as the ability to comprehend the items in the measures would provide valuable information.

- Description: The study is on the influence of comprehensive servicescape on shopping behaviour of road and rail travelling shoppers. The comprehensive servicescape is referred to as synchronization of the multidimensional servicescape dimensions, which are the physical environment, social environment, socially symbolic and the natural dimensions into one entity that the travellers encounter during the shopping exercise. The servicescape cues that include shoppers and the physical set-up of the service firm are important in influencing service quality evaluation and consumer satisfaction. The aim of this study was to establish the impact of servicescape on travelling shoppers’ buying behaviour and shopping motivations amongst different shoppers that were identified within the South African bus and railway stations. The bus and railway station environment induces an interesting type of shopping behaviour amongst the travelers. The purpose of the study was also to explore the travelling shoppers’ expectations and perceptions on the comprehensive servicescape within the bus station’s retail environment. Additionally the study attempted to address important gaps in the South African literature in respect of the influence of socialservicescape on the buyer behaviour and hedonic motivation of travelling shopper. The questionnaires used in the study were constructed along five dimensions of service quality containing statements linked to a five-point Likert-type interval scale anchored by “strongly agree” and “strongly disagree. Self administered questionnaires were used for data collection from the travelling shoppers through “mall intercept technique” and 300 questionnaires were collected from respondents. The academia benefits from this study from the comprehensive servicescape model of the South African bus and railway stations that was developed. The study built on literature by nvestigating the influence of the comprehensive servicescapes as perceived by travelling shoppers within the South African retail environment. Additionally it was shown both theoretically and empirically, that, that service quality in high contact service environment like the bus and railway station can best be explained by an analysis of the comprehensive servicescape or the multidimensional and hierarchical model. As a result of this study retailers will have a full picture on the specific needs, perception and expectations of road and rail travellers in relation to the quality of the stations’ servicescape, which retailers have to improve in order to increase customer patronage. It is assumed that retailers will be aware that store image and the store ambience should meet the challenges of the perceptions, motivations and consumer behaviour of travellers within the comprehensive servicescape of the station. This study provides a trigger effect to spatial planners to design high quality servicescape that will attract travellers for both hedonic and utilitarian shopping. Hirschman and Holbrook (1982) believed that shoppers derive pleasure from the experience of shopping itself, regardless of the joy from acquiring goods, this more so with travelling shoppers. A bus station can be both a growth node and a tourist attraction, if its features are attractive, therefore planners can benefit from this study. In this study theory that forms the bases of the influence of social servicescape on the behaviour of travelling shoppers that frequently visit and participate in shopping at various South African bus station retail outlets is provided. Additionally, this study provided empirical information on the relationships that exist amongst the characteristics of the South African Park Stations’ physical retail environments, user perceptions and interpersonal encounters. The behaviour of shopping travellers was extensively discussed to provide the background of theories and various models concerning shopping behaviour of travellers. Through this work, clarity on consumer behavioural trends of travelling shoppers in the South African retail sector is provided, which assist in differentiating retail products, services and segmentation of markets in a way that could enhance marketing effectiveness amongst the travelling shopping segment. Special attention was paid to factors that motivate road travellers’ choice of stores; the type of products they purchase and their decision making processes. Effort were made to identify, categorize and segment shopper typologies and their shopping behaviours. Effort was also made to discuss extensively the social and physical influences of environments in a retail environment such as that of the bus and railway station. The discussions in this study focussed on describing the comprehensive servicescape model dimensions which shoppers encountered during their shopping activity. The study also indicated the significance of the interaction of service staff with the customers in determining the service quality, customer satisfaction and the future intention of travelers. Additionally this study emphasised the importance of social encounters and perceptiveness to cues within the station, which determine whether they actively or passively are involved in the shopping encounter. The research findings reveal that, travellers perceive the servicescape within the bus station as unattractive and lack appropriate facilities. Furthermore travelers considered the two dimensions (store image and store ambience) of the store’s servicescape as one composite unit of the servicescape. This position is supported in literature, where it is argued that people respond to their environment holistically, rather than to individual stimuli. The travelling shoppers reveal that although they always find the shops from the bus station clean and neat, consumers expect a certain level of ambient environmental conditions to be present. The empirical findings in this study indicate that travelling shoppers are not interested in visiting the stores at the bus and railway station for shopping because merchandise from the bus station stores is poor in quality and unreliable; the surroundings at the station as unpleasant and the bus and railway station stores are congested. Thus, hasty shopping and spending more time or stay longer than planned for shopping at the bus and railway station is not useful to travelling shoppers. Therefore, travellers feel strongly that the shopping environment of the station is not conducive to shopping. These facilities (stations) are only used for travelling purposes; therefore there is a need for improvement in the retail and station facilities in order to increase shopping activities within this servicescape. The research findings reveal that shopping at the bus station seems to be driven by traditional needs such as functional and experiential motivations as well as travelrelated needs such as busstation-atmosphere-related and bus station-infrastructurerelated motivations. It was difficult to deduce a particular typology of shoppers in this environment, but due to the stress related to travelling. Passive shopping was observed amongst travellers, which is not a positive shopping behaviour for retailers.

- Description: Two developments that may impact house prices have dominated the residential property landscape in South Africa in recent years, namely government’s planned social housing developments and residential property value assessments carried out by local municipalities across South Africa for property tax purposes. Social housing developments are often plagued by “local opposition”, who argue that subsidised housing units may have a negative effect on adjacent non-subsidised residential housing. Negative preconceptions of social housing form the basis of this argument, which is commonly referred to as the “not-in-my-backyard” (NIMBY) syndrome. International studies conducted have, however, produced mixed results with some concluding that social housing developments lead to a reduction in nearby property prices, whilst others conclude that they lead to an improvement in surrounding property values. Currently, the state of the South African economy and demographics are limiting previously disadvantaged, poor peoples’ access to affordable and safe housing, and for this reason the basis of the NIMBY rationale deserves closer attention. In order to test the validity of the NIMBY rationale, this study examines, by means of the hedonic price method, the effect of an existing housing establishment catering for low-income earners (the Walmer/Gqebera Township) on adjacent property values in the suburb of Walmer, Port Elizabeth, Nelson Mandela Bay in the Eastern Cape. The study concludes that the low-cost housing development exerts a negative impact on the property values of nearby houses - the average owner of a non-subsidised residential property in Walmer would be willing to pay between R38 033 and R46 898 to be situated 200 metres further away from the Walmer Township. This conclusion is subject to three qualifications. The first is that the Walmer Township is not a recognised social housing development but merely a proxy for one. The second qualification is that a relatively small data set was used in this study and only one social housing development was considered. The third qualification is that the study period is from 1995 to 2009, which necessitated the adjustment of market prices to constant 2009 rands. For this purpose, data from the Port Elizabeth and Uitenhage section of the ABSA house price indices were used. It was not possible to disaggregate the indices further to obtain a Walmer-specific index. It is possible that an imperfect correlation exists between the Walmer property trend and the metropolitan (Port Elizabeth and Uitenhage) trend used in this study. Based on the results of this doctoral investigation it is recommended that a monthly rebate on property rates of between R269.40 and R332.19 be implemented for affected Walmer residents. This amount could be sufficient to mitigate the capital loss associated with proximity to the Walmer Township. In terms of the management of social housing projects, it is strongly recommended that the following occur in order to alleviate the NIMBY syndrome: existing dwellings should be renovated, tenants should be monitored, dwellings should be appropriately designed and maintained, the composition of the host neighbourhood should be assessed and the image of social housing should be improved. With regard to the renovation of dwellings, social housing site preference should be given to existing structures in need of renovation, as positive externalities are associated with the renovation of such properties. The monitoring of tenants needs to take place in order to ensure that the financial and behavioural obligations of the tenants are met, and that informal “shack dwellings” do not materialise on site, and finally, that tenant default rates remain low. The appropriate management of these projects will also aid in combating the perception that social housing developments lead to private residential property devaluation. In respect of residential property value assessments, many homeowners have recently argued that there is very little equivalence between the municipality’s valuations and true market values. This study uses, inter alia, the hedonic price model to investigate the accuracy of the Nelson Mandela Bay Municipality’s 2007/2008 valuation roll. The investigation was limited to the valuation roll applicable to the Walmer neighbourhood. The study finds that there is, on average, a 13.89 percent difference between market prices and the 2007/2008 municipal assessed values. In addition, this study finds that an attributebased hedonic price model produces property price predictions that are more in line with true market values. This finding is subject to two qualifications. The first qualification is that only the Walmer neighbourhood’s assessed values were considered, thus limiting the findings. The second qualification is that a relatively small data set was used.

- Description: This study provides an analysis of public debt dynamics with a view to assess the optimal size and composition of public debt in Zimbabwe that is consistent with maintaining public debt at sustainable levels. The analysis was performed by applying public debt data for Zimbabwe over the period 1980 to 2012. Robustness checks were conducted, using data for selected low income countries in the sub-Saharan Africa. The study was motivated by the public debt management concerns caused by the 2008/09 global financial crisis and the European sovereign debt crisis as well as the external public debt overhang experienced by Zimbabwe since the year 2000. The findings of the study complement existing research findings and information on public debt management of the International Monetary Fund (IMF) and other researchers. The major contribution of this thesis is the determination of optimal public debt thresholds for Zimbabwe. The optimal public debt thresholds were estimated from a joint analysis of the macroeconomic variables that affect public debt and the reaction of fiscal policy to changes in debt. The classical linear regression and Bayesian Vector Auto Regression (BVAR) models were applied to examine the drivers of debt accumulation and to assess the sensitivity of debt to macroeconomic shocks. The information from the drivers of public debt accumulation, together with the fiscal response mechanism was used to calibrate the long-run stable (optimal) public debt target. The optimal public debt threshold was also determined by assessing the link between public debt and economic growth. This assessment was carried out to establish the tipping point beyond which public debt adversely affects growth. Such a tipping point provides valuable information on the optimal size of public debt. The study also applied simulation approaches to determine the optimal composition of public debt. The results show that public debt dynamics in Zimbabwe largely comprised extensive stock flow adjustments emanating from extra budgetary expenditures to meet social and political related needs. The results of the assessment on the sensitivity of public debt to macroeconomic shocks show that Zimbabwe‟s public debt has been more vulnerable to economic growth, exchange rate and interest rate shocks. The significant influence of these variables highlights the role of automatic debt dynamics in public debt management. The results from the fiscal reaction function show that government has been responding positively to increases in public debt. This analysis also shows that government‟s policies are a-cyclical; as explained by the negative and insignificant response of the primary balance to the output gap. The dynamic stochastic simulation analysis suggests that Zimbabwe‟s public debt could follow an array of potential paths depending on the policy stance implemented by government. The simulated risk to public debt dynamics is larger, with an upper bound public debt to GDP ratio of 100 per cent and a lower bound public debt ratio of 32 per cent. The simulated lower bound provides a measure of a natural debt limit, which the government could adopt without fearing the risk of default. The results suggest that the main risks to public debt sustainability lie in growth shocks, whose volatility have been high for the period under study. The results from the analysis of growth and debt confirm the existence of an optimal growth maximising public debt ratio depicted by an inverted U-shaped relationship between public debt and economic growth. The optimal size of public debt was found to be at public debt levels of between 45-50 per cent of GDP. This means that higher public debt ratios have been associated with lower economic growth rates at debt levels above 50 per cent of GDP. The results are consistent with empirical findings for low income countries which suggest the existence of a debt laffer-curve. The results from an analysis of an optimal composition of public debt show a trade-off between a debt composition with more external concessional debt and one with more domestic debt. While a composition with more concessional borrowing was found to be desirable from a cost perspective, it proved to be less desirable from a risk perspective after taking into consideration stock flow adjustments due to changes in cross exchange rates. The findings of the study point to a need for the Zimbabwean government to swiftly respond to increases in public debt to control the swings in debt dynamics caused by macroeconomic shocks. The inverted U-shaped relationship between debt and growth suggests that government borrowing must be done in a way that simultaneously entrenches debt sustainability and ensures sustained economic growth rates in the medium to long-term. The study also highlights the need for counter-cyclical macroeconomic policies to avoid explosive debt dynamics emanating from frequent changes in the business cycle, and to minimise the interest/growth rate differential to ensure sustainable public debt dynamics. There is also a need for authorities to ensure a true balance between external and domestic borrowing to minimise the volatility in debt service costs caused by macroeconomic shocks. Generally, the findings from this study can assist in informing the policy agenda to address the imperatives of debt resolution, fiscal consolidation and economic growth acceleration.

This means that higher public debt ratios have been associated with lower economic growth rates at debt levels above 50 per cent of GDP. The results are consistent with empirical findings for low income countries which suggest the existence of a debt laffer-curve. The results from an analysis of an optimal composition of public debt show a trade-off between a debt composition with more external concessional debt and one with more domestic debt. While a composition with more concessional borrowing was found to be desirable from a cost perspective, it proved to be less desirable from a risk perspective after taking into consideration stock flow adjustments due to changes in cross exchange rates. The findings of the study point to a need for the Zimbabwean government to swiftly respond to increases in public debt to control the swings in debt dynamics caused by macroeconomic shocks. The inverted U-shaped relationship between debt and growth suggests that government borrowing must be done in a way that simultaneously entrenches debt sustainability and ensures sustained economic growth rates in the medium to long-term. The study also highlights the need for counter-cyclical macroeconomic policies to avoid explosive debt dynamics emanating from frequent changes in the business cycle, and to minimise the interest/growth rate differential to ensure sustainable public debt dynamics. There is also a need for authorities to ensure a true balance between external and domestic borrowing to minimise the volatility in debt service costs caused by macroeconomic shocks. Generally, the findings from this study can assist in informing the policy agenda to address the imperatives of debt resolution, fiscal consolidation and economic growth acceleration.

- Description: The role of institutions – economic freedom – is a critical determinant of economic growth, yet the global distribution of economic freedom is skewed. Economic freedom focuses on personal choice, the ability to make voluntary transactions, the freedom to compete and the security of property rights. The SADC is attempting to alleviate poverty and achieve sustainable development and economic growth. This thesis illustrates that economic freedom, in aggregate, and on an individual component basis, drives economic growth. The annual data for the 12 SADC counties from 2000 to 2009 are used to construct a panel data model to conduct the empirical analyses. Cross-sectional effects, as well as time (period) effects, are valid; and thus, a two-way error-component model is estimated. The Hausman test showed the regressors to be endogenous and correlated with the error term. The Pesaran CD test, suitable for dynamic panels, determined that cross-sections are interdependent; and the cross-correlation coefficient indicated a relatively weak, yet substantial, correlation. The LSDV two-way error-component model is re-estimated using the Driscoll and Kraay standard errors and time-demeaned data to correct for cross-sectional dependence. Given the endogeneity between the idiosyncratic disturbance term and the regressors, the presence of heteroskedasticity and serial correlation, as well as the interdependence amongst the cross-sections, the econometric model is then estimated using the two-step system general method of moments with forward orthogonal deviations – instead of differencing. The results meet all the post-estimation diagnostic requirements: the Arellano and Bond test for second-order serial correlation fails to reject the null hypothesis of no autocorrelation; theSargan test for over-identification fails to reject the null hypothesis that the over-identification restrictions are valid, and the difference-in-Hansen test fails to reject the null hypothesis that the instrument subsets are strictly exogenous. The empirical results confirm the a priori expectations. Economic freedom is a positive and significant driver of economic growth. Investment and economic openness are positively related to growth, whereas government debt decreases growth. Government consumption is an insignificant driver of a country’s growth. The Granger causality test confirmed the direction of causality; economic freedom precedes economic growth; and it is possible for the SADC to improve their growth rates by becoming economically freer. The coefficient of adjustment derived from the error-correction model indicates that the dynamic system takes approximately two years to adjust to the long-run structural level. The Koyck Transformation indicates that the relationship between economic freedom and growth is intertemporal, requiring a lag structure. An impulse-response function shows that a permanent, positive ‘shock’ to economic freedom results in an increase in economic growth, although the extent differs for each country, as well as for the different freedom components. The five individual economic freedom components are all highly significant and positive drivers of growth; however, the magnitude of the elasticity parameters varies. The causality amongst the components indicates that bidirectional causality is present. Therefore, improving economic freedom in one area improves economic freedom in another, creating a multiplier effect.

- Description: Businesses have been criticised for their contribution towards the ever-increasing rate of destruction of the natural environment. Although businesses have responded by adapting their management practices, production processes and products, they still face a number of challenges in reducing their environmental impact. One way in which businesses have responded to the environmental crisis is by implementing environmental management systems. Despite the importance of environmental management implementation, researchers have neglected to identify the antecedents that could lead to environmental management system implementation in South African small and medium-sized businesses. Indeed, much of the research on environmental management has concentrated on large business in Europe or the United States. The limited research that has been conducted on environmental management in small and medium-sized businesses has been descriptive in nature, and fails to produce results that are generalisable and that advance the understanding on this topic. Given this situation, the objective of this study was to develop and empirically test a theoretical model to explain the implementation of environmental management systems in small and medium-sized businesses. A quantitative survey methodology was adopted in this study to test the proposed theoretical model empirically. In total, 417 small and medium-sized businesses participated in the survey; 326 of these were not implementing an environmental management system, and 91 were implementing such a system. Descriptive statistics were used to summarise the sample data. The findings of this analysis suggest that the respondents had a favourable attitude toward environmental management systems; they were aware of environmental issues; they perceived themselves and their businesses as able to deal with the barriers to environmental management system implementation; they felt personally obligated to reduce their business‟ environmental impact; and they perceived actions aimed at reducing their businesses‟ environmental impact as socially desirable. To test the hypothesised relationships in the theoretical model, correlation and multiple regression analyses were used. The hypotheses dealing with the relationship between the environmental antecedents and the owner-manager‟s intention to implement an environmental management system, and the actual implementation of an environmental management system, were supported in this study. Thus, the environmental antecedents were found to be positively related to the small and medium-sized business owners‟ intention to implement an environmental management system; to their formal and informal implementation of an environmental management system; and to their practices related to waste management and legal compliance. Empirical evidence to support the hypothesised effect of resource constraints as a moderating variable was found in this study. In terms of environmental values, support was found for the moderating effect of egoistic, altruistic, and biospheric values. In terms of the biographical characteristics of the business owners, significant moderating effects were found for gender and age, but not for education. Gender influenced the relationships between the environmental antecedents, attitude towards an environmental management system and personal pro-environmental norms, and the intention to implement an environmental management system. Age moderated the relationship between subjective pro-environmental norms, waste management, and legal compliance. Given the empirical evidence provided in this study, it is recommended that greater awareness of environmental issues be fostered among small and medium-sized business owners as well as the individuals who influence their decision-making. There is also a need to reinforce the positive business outcomes of environmental management system implementation, as well as the personal and social obligations to protect the natural environment among small and medium-sized business owners.

- Description: This research deals with achieving and maintaining price stability in Sub-Saharan Africa (SSA) through the practice of monetary-policy transparency (MPT). On the one hand, MPT refers to a monetary strategy whereby the central bank is insulated from political influence and made accountable to society through disclosure of its policies, procedures, economic models, data and forecasts, operations and political practices (such as objectives, personnel independence, and the like). On the other hand, price stability refers to achieving and maintaining low and stable levels of inflation conducive for long-term planning and poverty alleviation. The primary objective of this research was to investigate MPT in SSA as it represents a powerful means whereby economic agents’ expectations may be coordinated and managed by the central bank to achieve its societal, objective function of low inflation. The empirical evidence shows that, first, a dependent central bank is more likely to slip into hyperinflation. Second, a SADC (2008) model central bank law is not independent enough to be used as a benchmark for any central bank or as a charter for a regional central bank. Third, the degree of central bank independence in SSA is relatively lower than that in industrialised economies. Fourth, the determinants of MPT in SSA are trade openness, and financial depth that are important factors influencing policy-makers to adopt monetary-policy transparency. Fifth, MPT is associated with a decline in the inflation rate. Sixth, MPT had no significant effect on economic output, whilst trade openness was positively associated with real GDP.

- Description: This research attempts to evaluate the stability of money demand functions and estimate monetary inflation models in the East African Community (EAC), using quarterly aggregate data that range from 2000Q1 to 2012Q3. We used Johansen co-integration analysis to estimate and analyse the stability of the M3 money demand model for each country member of the EAC. From this estimation, we derived a country-specific measure of money overhang. We compared its forecasting power of future inflation with that of money stock growth, and money stock available in the economy. Regarding country-specific money demand functions, with the exception of Uganda, we identified a reasonable and stable country-specific M3 money demand model. Also, for predicting future inflation, the estimation results showed that M3 money stock growth is more reliable in Burundi and in Kenya, while M3 money overhang is preferable in Rwanda and M3 money stock in Tanzania. As both country-specific and regional (EAC area) information on monetary quantity growth and its impact on price level is important to know in a monetary union, we considered the EAC area as a single market and attempted to estimate the aggregate (EAC area) demand functions for broad money M2 and M3 using Johansen co-integration analysis. The estimated long-run aggregate money demand models M2 and M3 appeared to be stable over the sample period. However, the aggregate M2 and M3 at the EAC level were proven to be weakly exogenous, which should discard them for consideration at the EAC level as the intermediate targets variables in order to achieve the overall objective of price stability in the EAC region. Instead, short-term interest rate should be given a prominent role in monetary policy framework at the EAC level.

Financial literacy training in the small, medium and microenterprises sector : effect on business growth in the Eastern Cape, South Africa

- Description: The centrality of financial literacy to business performance is increasingly becoming established in the literature, with several studies attributing business failures, especially in the small, medium and microenterprises (SMME) sector, to the failure of entrepreneurs to acquire needed levels of formal financial training. This emphasis represents a paradigm shift: small business failures were conventionally blamed on lack of access to capital, infrastructural deficits, lack of markets for SMME goods and services, regulatory constraints, and crime. In South Africa, and elsewhere in the developing world, this new orthodoxy has spurned new policy interventions aimed at improving the financial literacy levels in the SMME sector. Such is the drive to entrench formal literacy provisioning in the SMME sector that some microcredit providers now bundle financial management training into their SMME loan packages. However, there is a dearth of empirical studies that demonstrate, in any conclusive way, the effect of financial literacy training on small business growth and sustainability. The question, therefore, about whether formal financial literacy training actually leads to significant improvements in turnover levels and growth appears to be answered more as advocacy rather than on the basis of empirical evidence. It is against the backdrop of these arguments that the thesis adopted a quasi experimental design to study the business performance of a sample of SMME entrepreneurs who had received financial literacy training (the “treatment group”) at least two years before the study’s commencement and those who had had no financial literacy training at all (the “control group”). The objective was to determine whether any differences in business growth could be attributed to exposure to formal financial management training or the lack thereof. A survey was conducted with 40 respondents from each of the two groups (n = 80). The survey was triangulated with in-depth interviews of a randomly selected sample 10 of SMME operators from each of the two groups. The interviews sought to uncover the entrepreneurs’ narratives regarding the sources and salience of financial literacy in the sector. The study was conducted among SMME operators in Port Elizabeth, East London and Mthatha – the Eastern Cape’s major centres of commerce and industry. Data estimation was conducted using the Difference In Difference (DID) estimation model to determine whether financial literacy training has had any effect on the turnover of training recipients’ businesses (the treatment group) over that of non-training recipients (the control group). Also, the DID coefficient was used as a growth rate indicator to determine whether growth has occurred in training recipients’ businesses over non-training recipients businesses as a result of having received financial literacy training. The Propensity Score Matching (PSM) was used to estimate the average treatment effect (ATE) and the average treatment effect on the treated (ATET). Quantile DID correlations with covariates were also run to reveal the relationship between turnover (a growth variable) and the covariates as possible influencers of firm performance. The key findings of the study were that based on the specific financial variables tested, some basic financial management knowledge existed among members of the two groups of SMME operators, but there was very minimal application of the knowledge in the day-to-day running of the business. Operators utilise both formal financial literacy training and informal knowledge sources in the operation of their businesses. The study also found that in comparison, the difference in turnover between the treatment and control group at follow-up period was significant at a P value of 0.000. This gave rise to an overall DID P value of 0.000 in the estimation. However, the significance was in favour of control group businesses as the business of respondents in the “control group” (with no financial literacy training) performed better than that of respondents in the “treatment group” (who had received financial literacy training). Finally, the study found that financial literacy training had no effect on the growth of businesses in the short term as the growth rate of turnover of the treatment group was lower than that of the control group and the difference between the two rates was significant at a P value of 0.025. Also, compared to itself, the change in turnover levels of the treatment group was not significant in the pre- and post-training periods as revealed by the PSM ATET estimation result. Minimal changes in turnover of the treatment group was not significant at a P value of 0.124. The study concludes from these findings that while financial literacy remains a salient factor in business, scholarship about the real significance of financial literacy training on small business performance in the short term stands on a relatively shaky empirical foundation, especially when viewed against the background that many SMME entrepreneurs also rely on informal knowledge sources to make everyday business decisions. The study thus highlights the imperative of ensuring that knowledge-related interventions in the SMME sector draws on both formal and informal sources of knowledge.
