    Using 3D Printing Technology for Manufacturing Interior Aesthetic Components for Customisation in the Automotive Industry
    (University of the Witwatersrand, Johannesburg, 2024) Mbambo, Nondumiso
    The research is a business venture proposal focusing on exploring the concept of automobile interior customisation through a 3D printing. The research gap of inclusivity in the current offering of the automobile interior was articulated. Theories of digital transformation, digital maturity, innovation, lean innovation and entrepreneurship were used to inform this study. The conceptual framework was developed using the variables of age, gender, customisation, connectedness and purchasing intent. The qualitative research strategy was adopted for the research and probability sampling was used to sample random respondents. Reliability and validity were determined using CFA and SEM. The findings of the study revealed that the concept of customisation is not dependent on age and gender therefore an inference drawn was that market segmentation ought to be done by needs and preferences as opposed to demographics. The findings further revealed that there is a need for this customisation offering as both customisation and connectedness were found to be drivers of purchasing intent. The business case for Mageza 3D printing was advised by the findings of the study where the target market was identified. The business strategy focused on the market penetration, the staggered approach in the operations rollout to 2035 as well as the marketing plan for the concept of customisation. The business showed profitability of 15% from the first year reaching 26% by the fifth year. The main limitation of the study was in the research methodology adopted whereby the inclusion of a qualitative research strategy would have offered a more holistic understanding of concept buy-in across the value chain. In this regard, future research was recommended to assist in solidifying this business case

    Crypto Connections: Unravelling African Stock Markets and Cryptocurrencies in the COVID-19 Era
    (University of the Witwatersrand, Johannesburg, 2024) Marcus, Howard; Odei-Mensah, Jones
    Since their introduction in 2019, cryptocurrencies have become increasingly popular in the African markets. Cryptocurrencies are seen as disruptive technology based on cryptographical technologies and do not share features related to the real economy. Based on this characteristic, one hypothesises that these assets are a perfect diversification instrument during periods of high volatility, particularly as portfolio managers look for new avenues to manage risk. The main aim of this study was broadly focused on the interdependence and co-movement relationship of cryptocurrencies and African stock markets during periods of severe market stress, such as during the COVID-19 pandemic. This study was mainly concerned with those aspects of connectedness that relate to transmission through financial markets. This study sought to examine the co-movement relationships, determine the extent of integration and establish the direction of spillover by replicating modelling techniques proposed by Diebold and Yilmaz (2009; 2012) and Barunik and Krehlik (2018). These techniques measure connectedness using a spillover index, which follows a variance decomposition approach of a vector autoregressive model. The second technique allows for the estimation of connectedness to variables because of heterogeneous frequency responses to shocks. By studying the connectedness of Bitcoin, Ethereum, Tether, Binance Coin, and XRP and the five largest African stock markets based on market capitalisation (South Africa, Nigeria, Morocco, Egypt, and Kenya), the study observed that the COVID-19 sub-sample period contributed most to connectedness at 31.79% relative to the pre-COVID period at 23.67%. The highest contributors to connectedness in both periods are Bitcoin and Ethereum, with Tether being the lowest. These results indicate that information flow mostly comes from the stock markets rather than cryptocurrencies. Also, from the frequency-domain results, across both periods, the most significant contributor to connectedness is observed in the short-term being frequency 1, accounting for 17,74% and 24.77%, and frequency 2, 4.35% and 5.16% in the pre-COVID and COVID periods respectively, while the medium- term and long-term accounting for relatively more minor proportions. Thus, contagion is highest in the short term given connectedness results, thus leading to lower diversification across the short term; however, diversification benefits are noted across more extended term periods. In addition, in the longer-term period, the change in connectedness is relatively tiny. The findings of this study suggest that cryptocurrencies could be an alternative to diversifying risk in African equities. Diversification is essential for long-term investors and regulators as they build resilience in the financial markets during a crisis. This study informs policymakers and governments on the need to regulate markets to optimise diversification, safe haven, and hedging benefits across varied market conditions
