Item The effects of individual and organizational factors on ethical behavior in the South African construction industry(2019) Makonye, ChidoEmployees often face many difficult situations that demand ethical decision making from the viewpoint of society and organizations. Various factors influence the outcome of ethical or unethical decision-making and behaviour of employees. This paper briefly examined some of the major factors that may affect ethical behaviour in construction companies. The strength of these factors may vary from individuals to individuals, organizations to organizations, and situation to situation. The factors that were investigated are personal values, corporate ethical values and the organisational climate. Age and gender were used as moderators in this study. South Africa is a developing country in which many private and public organizations are being faced with a lot of fraud and corruption. It is not only in private organization but also the government. This call for an investigation on ethical behaviour but to solve a problem one must find the source of the problem. The study was designed to answer the major question: Are there any significance relationships between personal values, corporate values and organisational climate and ethical behaviour in the South African construction industry? The researcher employed a quantitative research method. Data collection was done by use of questionnaires distributed to various construction companies. A computer programmer called SPSS version 25 and Microsoft excel were used to analyse data. Descriptive statistics was used to interpret data collected from the first section of the questionnaire that is the biographic information. Linear regression and correlations were used to test the proposed hypothesis. Multiple regression was used to test the moderation effect of age and gender. The findings largely confirm previous studies that personal values and corporate values influence ethical behaviour. However contrary to some previous studies, there was no significant relationship between ethical behaviour and organisational climate. Conclusions, findings and recommendations were drawn from the results.Item Impact of oil price shocks on stock returns: evidence from selected Southeast Asian economies(2017) Siddiqui, Ammar AhmedThis paper investigates the impact of oil price shocks on stock market returns in selected Southeast Asian countries. We selected five countries, those are Indonesia, Singapore, Malaysia Thailand and Philippine. We employ autoregressive distributed lag model (ARDL) and VECM model in the analysis. We model both positive oil price shock and negative oil price shock. We find that the real Brent price is positively correlated with all the stock markets in the selected countries. The results of ARDL model indicate that positive oil price shock exhibits a negative impact on the stock market returns while lag one negative oil price shock exhibits a positive impact on the stock market returns in the short run. However, only Indonesia and Singapore exhibit a significant response to positive and negative oil shocks in the ARDL model. The cointegration analysis indicates a long run causal relationship from oil price to stock market returns for Malaysia and Singapore. This result is confirmed by the error correction model with significant and negative but low speed of adjustment.Item Online grocery shopping in South Africa: underlying motivations and challenges(2022) Maja, Kelelo MpananaWhile many countries imposed COVID-19-related restrictions, global online shopping adoption has recently improved, but not at the same rate as fashion and electronics. However, the disparity among the online segments is yet to be established. The study identified and examined factors influencing South African consumers’ intention to use online grocery shopping. A model was proposed to investigate and test hypotheses relating to effects of social influence (SI), word of mouth (WoM), brand intent, convenience, and order fulfilment constructs on customer purchase. Data was collected from 839 respondents via an online questionnaire. The Structural Equation Modelling (SEM) technique was used to evaluate the relationships between the constructs and customer purchase intention. Social influence, WoM, convenience, and order fulfilment significantly influenced customer purchase intentions, while brand intent showed an insignificant impact. Also, COVID-19 was found to significantly moderate the relationship between convenience and purchase intention, but Age and experience were insignificant.Item The perceived impact of video-on-demand services adoption on subscription TV services in South Africa(2022) Njomo, FannaDigital disruption in the media and entertainment industry has changed how subscribers acquire, distribute, and consume content. Technological innovation facilitated the evolution of television to the introduction of services that compete for viewership from the same subscriber base. The main aim of this study was to establish the impact of the introduction of video-on-demand services on the subscriber base of traditional subscription TV services that previously had a monopoly in South Africa. Following the study’s objectives, theoretical constructs were derived from literature to understand subscribers’ expectations and competitiveness of both services, the technological innovations driving both services, how satisfied are subscribers with each service as they choose their preferred service. The study used a cross-sectional quantitative method, and primary data were collected using a self-administered questionnaire from 233 subscribers who have an active media and entertainment subscription. The study found that video-on-demand services are adopting disruptive technologies that are changing subscriber content watching behaviour, subscribers are technologically savvy and adapting to digital transformation in the industry and use devices that were not used to consume content and introduced additional screens and not limited by linear scheduling. The study's findings showed that subscribers are cord-cutting and cord-shaving while others are cord-nevers as they never subscribe to traditional subscription services. Therefore, the new video-on-demand (VOD) services negatively impacted the traditional subscription TV service subscriber base. Traditional subscription TV services must implement innovations in broadcasting to be competitive and retain some of their subscribers as they acquire new subscribers.
