Item Sustainable community development and corporate social investments by a platinum mining company in South Africa(University of the Witwatersrand, Johannesburg, 2024) Motaung, Lelentle; Mati, Jacob MwathiSouth African mining companies implement corporate social investment (CSI) projects meant to benefit host communities by addressing various development needs. However, constant conflicts arise between these communities and mining companies despite these CSI projects. Using a qualitative case study approach, this study sought to understand reasons for the persistence of this conflict. The study applied the Ladder of Citizen Participation (Arnstein, 1969) in analysing the design and implementation of CSI programmes of one platinum mining company in South Africa. Findings suggest that existing conflicts reflect a dissonance between the mining company’s CSI objectives and community development needs, illustrated by the poor quality of engagement with local communities in determining CSI priorities. Specifically, inferior quality community consultations, lack of communication about forums for consultation and poor community representation in consultation processes hinder successful prioritisation of community needs in CSI objectives. In addition, the mining company seems to always act in its own interest by prioritising exclusionary elitism in its community engagement strategies. This, coupled with a lack of regular monitoring and evaluation, leads to misalignment between the CSI and sustainable community development objectives, and impedes the successful implementation of CSI initiatives.Item Senior Managers’ perception of their role in facilitating digital transformation in the public sector – South Africa(University of the Witwatersrand, Johannesburg, 2024) Mosia, Emanuel Mmuelli; Craffert, LeonaDigital transformation is a new phenomenon in the public sector. Previous studies have also found that public sector is performing poorly compared to private sector in their endeavours to transform. The study was intended to establish how senior managers perceive their role in facilitating digital transformation of the Department, excluding the actual assessment of digital maturity. The study drew guidance from Unified Model of Digital Maturity and Dynamic Capabilities Framework which both demonstrate the role of senior managers in the rapid changing environment due to technological disruptions. The study used semi- structured interviews to collect data from the population of 386 senior managers, where 15 senior managers were interviewed either face-to-face or virtually. The study finds that senior managers understanding of their role in facilitating digital transformation is fair to average. Their understanding of digital transformation is a simple switch from paper to paperless. Additionally, silo approach was found to be one of the impeders of digital transformation in the Department. The Department should be developing digital transformation strategy to guide the senior managers, coalesce all the efforts and be intentional in investing in digital transformation of the Department.Item The Influence of Regulatory Interventions on Consumption Behaviour of Sugar-Sweetened Beverages in South Africa(University of the Witwatersrand, Johannesburg, 2024) Mosenogi, Kgomotso; Saruchera, SannyThe increasing rates of chronic diseases as a result of weight gain, which lead to increased mortality rates, are linked to consuming processed foods and are progressively becoming a growing concern in South Africa. In response, the South African government imposed a sugar tax to control the consumption of sugar-sweetened beverages (SSBs), as these beverages are associated with health issues such as diabetes and obesity. However, research on the influence of regulatory interventions, such as sugar taxes, on SSB consumption behaviour is lacking. Through the assessment of the three marketing mix components, namely, product, price, and promotion, this study investigated the influence of various regulatory interventions on SSB consumption behaviour in South Africa. Using the Consumption Behaviour theory as a framework that acknowledges that internal and external factors can influence a purchase decision, the study explores how Product Reformulations, Product Size, Product Packaging, Price, and Promotion affect SSB consumption behaviour among South African consumers. The exploratory study's methodology was quantitative conducted through a self- administered survey. Data was collected from 297 South African participants between the ages of 18 and 59, and the results were analysed using SPSS version 28. The results validated the hypothesis that Product Formulation Regulation, Price Regulation and Promotion Regulation significantly influenced SSB consumption behaviour. On the other hand, there was insignificant effect from Product Size Regulation. The study excluded the hypothesis on Product Packaging Regulation because of concerns about its validity. The study enhances the existing body of knowledge and comprehension of how regulatory interventions influence consumption behaviour. Furthermore, it offers practical recommendations for consumers, policymakers, SSB manufacturers and healthcare practitioners. The enhanced understanding can impact policy decisions and public health initiatives aimed at addressing the detrimental health effects associated with high SSB intake in South Africa.Item Technological and economic catch up in the biotechnology sectoral innovation system in South Africa(University of the Witwatersrand, Johannesburg, 2024) Moonsamy, Ghaneshree; Soumonni, OgundiranBased on the global drive to move towards knowledge-based economies, several countries have identified biotechnology as a sector of interest for economic development. South Africa too, has identified this sector as a means to stimulate economic growth, bridge the inequality gap and reduce unemployment. Despite significant efforts to date, the impact and performance of the biotechnology sector on the socio-economic status of South Africa has been uninspiring. This study aims to evaluate the existing biotech-based sectoral system of innovation and assess potential pathways that may be undertaken to achieve technological and eventual economic catch-up by the country. Windows of opportunity that may entail technological, demand and institutional/public policies were also evaluated. This study used a mixed method approach, which firstly assessed the performance of the South African biotech sectoral system of innovation (SSI) in comparison to five other countries of interest. Thereafter, semi-structured interviews were conducted with 20 participants involved in the biotech triple helix system of innovation. Key findings indicated that South Africa performed poorly in comparison to other countries evaluated, which included the USA, Germany, Mexico, India and Singapore. Regardless of having pockets of excellence and enabling mechanisms such as supporting policies and available infrastructure, organisational capabilities and a highly fragmented national system of innovation are major limitations of the sector. These findings present a key message in that further, significant efforts are required to build on existing capabilities such that the country is able to increase its global standing in terms of biotech-based innovation. As a developing, upper middle income county, South Africa is unfortunately way of the mark in terms of economic catch up, however pathways of catch-up, specifically technology, demand and policy windows of opportunity do exist and need to be harnessed.Item The successful implementation of LNG aggregation for market development(University of the Witwatersrand, Johannesburg, 2024) Moodley, Letitia Anthia; Young, BruceIn the context of the global transition towards sustainability, most countries still grapple with energy security issues and a heavy reliance on fossil fuels as an energy source. Natural gas is proposed as a significant source of energy within global future efforts to diversify the energy system. The development of the natural gas market is therefore imperative to achieve the global energy transition goals as LNG has been identified as an ideal transitionary fuel (Hafeznia, Pourfayaz, & Maleki, 2017; Mohammad, Mohamad Ishak, Mustapa, & Ayodele, 2021; Safari, Das, Langhelle, Roy, & Assadi, 2019). This research report assesses the types of LNG aggregation implemented by countries and the effectiveness of the implementation of LNG aggregation as an energy policy instrument. The determinants of the identified criteria, based on the 4-As framework, were collected, and normalised via the unitization method. Multi-criteria analysis was utilized for the aggregation of the determinants, allowing for the analysis of the function which, in this research report, is the success of LNG aggregation implementation as energy policy. The analysis provides for the top performing country based on the indicators identified for each criterion of the 4As framework, from which, the success factors of LNG aggregation are unpacked. Sixty-four countries are identified as trading in LNG, of which, eleven were identified as having implemented LNG aggregation strategies. The criteria of the 4A’s framework, affordability, availability, acceptability, and applicability, are utilised to define a set of indicators which allowed the eleven countries to be ranked based on a performance score. The United States, ranking first, implements a block aggregation strategy which has been complimented by the country’s success factors. The country has a mature legal environment which has provided reassurance to the global market and resulted in the attraction of investment, transforming the country into a net exporter of energy. The United States has flexibility in its policies which allowed for the production of non- conventional Shale gas. Russia, ranking second, implements single buyer and brokerage aggregation strategies which has enabled the country to become a significant participant within the global LNG market. This successful implementation of the aggregation strategy is underpinned by the vertical integration of the state-owned gas company. The third ranked country, Trinidad and Tobago, has successfully implemented a single buyer, single seller aggregation strategy which allowed the infant market to develop over time. The country strives towards the ease of doing business for global participants, provides Created by Terri Carmichael at Wits Business School; terri.carmichael@wbs.ac.za iii government support and the ability to absorb market fluctuations. Lastly, Singapore implements a single-buyer aggregation strategy. The success factors, of which, have been the countries complimentary incentives for investment and trade, government support, policy driven incentives, a well-developed legal system and agility within policyItem Data centralisation as a key enabler of digital transformation in South African banks(University of the Witwatersrand, Johannesburg, 2024) Monyamane, Keitumetse Lucy; Magida, AyandaThis research report investigates the inhibitors of data centralisation in digital transformation. The study focuses on retail banks in South Africa, as these institutions aim to become customer-centric. However, the adoption of digital technologies and data strategy implementation are cumbersome due to legacy systems. The existing theoretical framework is that organisations undergoing a transformation need to understand how to adopt and implement new technology. It leverages emerging technologies, strategic organisational direction, and competitive factors as drivers for adoption. Literature specifies that there needs to be an informed digital culture and data operating model championed by leadership to ensure organisational change. Retail banks face challenges as they hold valuable customer data to offer exceptional user experience but have challenges becoming data-driven organisations due to silos, bureaucracy, and implantation capabilities. Qualitative research, in the form of semi-structured interviews, was conducted with executives and middle management from the top three retail banks in South Africa. The study found that there is a gap in data strategy formation to address a digital strategy, silos in the operating model, data roles and skills, data-driven culture and implementation challenges to manage data and integrate to new technologies. It was found that data centralisation requires the support of a leadership drive. Several challenges were highlighted in line with the research questions, and recommendations were proposed: lead a data-driven strategy, adopt a customer- centric culture, expand data capabilities, centralise data management, and modernise architecture and technologyItem Indigenous knowledge and science, technology, and innovation-driven systems for the healthcare industry in South Africa(University of the Witwatersrand, Johannesburg, 2024) Moloto, Kagiso Christopher; Ramoroka, KgaboThe National Innovation System (NIS) of South Africa, which is predominantly driven by Science, Technology, and Innovation (STI) is entrusted to help elevate the developmental challenges faced by many South Africans. The integration of Indigenous Knowledge System (IKS) into the STI-driven NIS particularly for the healthcare sector could potentially provide solutions to eradicate the triple challenges of poverty, unemployment, and inequality. There is, therefore, a need for a robust institutional support system for a sustainable integration of STI and IKS which could ultimately help increase grassroots innovations. It is worth noting that there is a general agreement between and amongst policymakers, scholars, and industry role payers that the performance of a country’s economy, in a globalising knowledge economy depends to a large degree, on innovation and knowledge. In order to transform and enhance the responsiveness of the STI-driven NIS of South Africa, there is a need to explore additional mechanisms on how to incorporate Indigenous Knowledge (IK) and IKS into the formal STI knowledge systems. With proper policy formulation around this incorporation, South Africa can set itself on a path of development, driven by grassroots innovation for effective medicinal products that can be of benefit for the healthcare sector and South African citizens at large. This research study aims to explore the extent to which IK, which is the main ingredient of African traditional medicines Research, Development, and Innovation (RDI) is integrated in the South African STI-led NIS for the healthcare system as part of addressing the socio-economic challenges faced by South Africans. The study also explores some of the challenges that that hinder the integration of IKS in the NIS of South Africa, particularly around African traditional medicine. By the use of document analysis and semi-structured interviews, the study suggests that, although there is room for improvement, there is to some extent integration of IKS in the NIS of South Africa from a policy point of view. Numerous challenges that hinder full integration of the IKS in the NIS are also discussed. The study recommends that in order for South Africa to speed track the integration of IKS in the NIS particularly for the healthcare sector, the National 3 Indigenous Knowledge System Office (NIKSO) could perhaps be upgraded into a full, independent institute or science council that primarily focusses on IKSItem Forecasting Stock Prices: Do Taylor Rule Fundamentals Matter?(Malikane, Christopher, 2024) Molefe, ThaboWe build on studies by Ince et al. (2016), and Dladla and Malikane (2019) to explore the role of Taylor rule fundamentals in forecasting stock market returns in a small open economy. We investigate a mix of 11 countries from 1970 to 2022. We derive a stock return forecasting model using the dividend yield interest rate spread and introduce Taylor rule fundamentals into our model using Taylor’s (1993) rule. We compare the performance of our model to the autoregressive with lag-2 benchmark model and the historical average using Theil’s U, Diebold and Mariano’s (1995) MSE-T, and Harvey et al.’s (1998) ENC-T statistics to test for relative forecast accuracy, equal forecast ability, and model encompassing. Since the models are linear and nested, we follow McCracken (2007) in using asymptotic critical values for MSE tests and proceed to also follow Clark and McCracken (2007) in using asymptotic critical values for ENC tests. We split the data 50-50 and conduct an OLS regression on the in-sample portion of the data to obtain parameters. We obtain in-sample results that show the signs of the coefficients for most of our endogenous variables to be as per literature. The sign of the coefficient of inflation is negative in line with studies by Sousa, Vivian, and Wohar (2016), and Cooper and Priestley (2009) among others, and the output gap has ambiguous signs in line with Good News Case (GNC) and Bad News Case (BNC) by Blanchard (1981). However, the sign of the coefficient of the real effective exchange rate is positive for most countries in contrast to the reviewed literature by Wong (2017), and Hau and Rey (2006). We conduct out-of-sample forecasting using the recursive method due to its sensitivity to data structure changes and adaptability to data patterns. The results of the out-of- sample analysis show our model outperforming the autoregressive-lag 2 benchmark model for the 3-month horizon US and Brazil, and the 12-month horizon for most countries. It also outperforms the 3-month horizon Australia, and the 12-month horizon Poland historical average benchmarksItem Examining the influence of digital payment adoption on the digital divide in Kagiso township, South Africa(University of the Witwatersrand, Johannesburg, 2024) Mokgwatsane, Malengolo; Godspower-Akpomiemie, EuphemiaDigital payment systems have become increasingly popular and a vehicle for financial inclusion and access to financial services. However, as technological advancements progress, there remains a population segment that is left behind in terms of adoption and access. Digital payment systems are generally not adopted by township residents in South Africa. This is due to the uneven telecommunications infrastructure in South Africa and its limited availability in the townships. This study investigates the influence of tap-to-pay digital payments on the existing digital divide in Kagiso township and the factors that impact adoption and usage of this technology. This study adopted a qualitative research methodology that involved conducting face-to-face interviews with 12 respondents from Kagiso township. The respondents’ feedback was consolidated and analysed to uncover key findings. The findings revealed the presence of a digital divide in access and availability within Kagiso township, characterised by challenges stemming from poor infrastructure and limited access to technology, worsened by an uneven distribution of ICT. Furthermore, this study revealed lack of awareness and understanding of tap-to-pay, safety and security, unemployment and socioeconomic challenges as significant barriers to the adoption and usage of tap-to-pay payment systems in the township. Therefore, it is advisable for the South African government to increase investment in infrastructural upgrades to improve the accessibility and availability of digital technologies in the townships while also collaborating with the private sector to support initiatives aimed at addressing the digital divide in the townships. The collaboration with the private sector, particularly the telecommunications companies is crucial in driving these efforts. By leveraging market opportunities, telecommunication companies can implement strategies that accelerate the adoption of new technologies. One such strategy is investment in fiber optic networks to provide high-speed internet access in townships.Item Digital literacy, perceived risk, and purchase intention in the South African online retail sector(University of the Witwatersrand, Johannesburg, 2024) Mokgoko, Keetse Hazel; Anning, Thomas DorsonOnline purchase behavior, while steadily growing, is not as prevalent in South African as in other, developed countries. Although South Africa has a significant population of internet users and widespread internet access, it has not resulted in a corresponding rise in the adoption of online commerce. This study aimed to establish whether certain factors, namely digital literacy, perceived risk, ease of use and usefulness, influence consumers’ intention to adopt online retail purchasing in South Africa. Data was gathered from 215 participants in South Africa through an online questionnaire survey. Perceived risk and perceived ease of use were found to be positively and significantly correlated with digital literacy. In contrast to earlier studies, the results suggest that digital literacy does not have a significant influence on an individual’s perception of the usefulness of technology. The study also found no substantial correlation between perceived ease of use and an individual’s online purchasing intentions. Perceived usefulness was found to be a key determinant of consumer’s purchase intentions. The results of this study are highly significant to retailers, government bodies, and other industries, as they emphasise the significance of taking appropriate actions to improve the digital literacy skills of the general public to drive the adoption of e-commerce. The results also, demonstrate the importance of raising awareness regarding risk perception in the context of online shopping. This can be achieved by marketing campaigns that focus on promoting online security awareness.
