Cellphone banking adoption and continuance of use in an internet banking context : a study of consumers'cross-channel cognitive evaluations
(Stellenbosch : Stellenbosch University, 2013-03) Nel, Jacques; Boshoff, Christo; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Business Management.
ENGLISH ABSTRACT: The convergence of the Internet, wireless technologies, and mobile devices has led to the development of a new paradigm of transacting, namely, mobile commerce. Because banking activities are easily digitised and automated, banks have seized the mobile transacting opportunity and have developed cellphone banking applications that allow more flexibility for bank clients than internet banking in terms of anywhere, anytime banking. For banks, considering the benefits associated with multi-channel customers, the ideal situation would be that bank clients using internet banking also adopt and continue to use cellphone banking in the future. Therefore, to assist marketing managers with the development of marketing strategies to enhance the concurrent use of internet and cellphone banking, this study investigates the influence of internet banking cognitive evaluations on the perceived usefulness and the perceived ease of use of cellphone banking in the formation of the intention to use and the continuance of use intention of cellphone banking. A literature review revealed that two consumer behaviour theories can guide crosschannel cognitive evaluations between the internet banking and cellphone banking channel namely, expectation-transfer theory and status quo bias theory. In the context of this study, expectation-transfer theory can explain cross-channel evaluative synergies from the internet banking channel to the cellphone banking channel, as well as dissynergies; whilst status quo bias underpins only evaluative dissynergies. These theories point to internet banking beliefs that could influence the perceived ease of use and perceived usefulness of cellphone banking. Based on the literature review, a conceptual model was developed of the formation of intention to use and the continuance of use intention of cellphone banking in an internet banking context. To assess the validity of the model empirically, data were collected from 678 users of only internet banking and 491 users of both internet and cellphone banking. The data collected in the empirical phase of the study were analysed using the structural equations modelling (SEM) software program AMOS 20.0. The results revealed that the perceived convenience and time saving of internet banking positively influence the perceived usefulness of cellphone banking for the users of both internet and cellphone banking. On the other hand, only the perceived convenience of internet banking influenced the cellphone banking usefulness perceptions of the users of only internet banking. Furthermore, internet banking trust and risk perceptions only influenced the cellphone banking usefulness perceptions of the users of only internet banking. Expectation-transfer in both cohorts was also confirmed between the ease of use perceptions of internet banking and the perceived ease of use of cellphone banking. The results also confirmed that internet banking facilitating conditions negatively influence the perceived usefulness of cellphone banking (evidence of status quo bias). The theoretical contribution of the study is apparent at three different levels. Firstly, the conceptual model of cross-channel cognitive evaluations extends the Technology Acceptance Model (TAM) with beliefs of a related technology as the determinants of perceived usefulness and perceived ease of use. Secondly, the study provides more insights into how cross-channel cognitive evaluations influence the formation of intention to use and the continuance of use intention of cellphone banking. And lastly, the study identifies additional sources of expectation-transfer and status-quo bias in the multichannel marketing context. The study provides valuable insights into internet – cellphone banking multi-channel consumer behaviour that should be considered by managers in the development of cellphone banking marketing strategies. To facilitate the conversion from internet banking to the concurrent usage of internet and cellphone banking, managers of cellphone banking services must ensure that the internet banking service is reliable and risk free. Equally important, cellphone banking must be marketed as a complementary channel to internet banking. In other words, the usefulness of cellphone banking must be emphasised in situations when the bank client is not near a computer to do internet banking or when he/she does not have the time or money to use a computer for internet banking. And lastly, to enhance the adoption of cellphone banking marketing communications must emphasise the similarities between internet and cellphone banking so that expectation-transfer between the two channels can influence behavioural intentions to adopt cellphone banking. Based on the results of the study, several recommendations can be made to enhance the continuance of use of cellphone banking. Firstly, marketing communications must remind the concurrent users of internet and cellphone banking of why they are using cellphone banking. The most important reason to remind them of is the usefulness of cellphone banking in situations where there is a lack of internet banking facilitating conditions. Marketing managers should also take note that cellphone banking users do not draw on internet banking trust and risk perceptions to form perceptions of the usefulness of cellphone banking. It may be that they only consider trust and risk perceptions directly related to cellphone banking. This conclusion emphasises the importance of cellphone banking trust and risk perceptions in cellphone banking continuance of use behaviour. Finally, the study quantified the influence of internet banking cognitive evaluations on the formation of intention to use and the continuance of use intention of cellphone banking. Considering this result, the study provides valuable information for marketing managers of cellphone services. The methodology employed can also guide future studies exploring cross-channel evaluations in a multi-channel marketing context.
Consumer ethnocentrism and attitudes towards domestic and foreign products : a South African study
(Stellenbosch : Stellenbosch University, 2011-12) Pentz, Christian Donald; Terblanche, N. S.; Boshoff, Christo; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Business Management.
ENGLISH ABSTRACT: The continued growth of international trade has resulted in levels of global product availability that is not only unprecedented, but would have been regarded as impossible not too long ago. Products of almost every conceivable national origin are now readily available in numerous countries throughout the world. Because the “country of origin” label of a product is a factor that could influence the buying behaviour of consumers, prescient international marketers know that they need to investigate consumer attitudes toward both domestic and imported products and the findings of these investigations should be used to formulate more effective marketing strategies. Previous research into the “country of origin” phenomenon has focused on consumer ethnocentrism as a possible reason why consumers would buy a domestic rather than an imported product. The basic premise of the concept of consumer ethnocentrism is that the attitudes and purchase intentions of consumers can be influenced by what could be called nationalistic emotions. In short, consumer ethnocentrism implies that consumers might regard the purchase of foreign products as “wrong”, as it might harm the domestic economy and result in job losses in industries that compete with imports. As a result, consumer ethnocentrism has been actively researched in developed countries in particular, but there seems to be a dearth of knowledge about consumer ethnocentrism in developing countries. This study‟s primary objective is therefore to investigate consumer ethnocentrism in a developing country, in this case South Africa. The study is based on a review of the literature, covering aspects such as marketing, consumer behaviour, globalisation and especially the phenomena of country of origin and consumer ethnocentrism. The literature review was followed by an empirical, survey-based study investigating consumer ethnocentrism in South Africa. A novel contribution of this study is that consumer ethnocentrism was investigated among different racial groups in the same country. This was done to assess whether there are significant similarities and/or differences between different racial groups in terms of consumer ethnocentrism and any of the attitudinal variables relevant to international marketing. A conceptual model (containing sixteen variables) was developed as a guideline from the literature review to investigate consumer ethnocentrism and how it could influence the attitudes of South African consumers (of different races) towards the import of foreign products (Chinese clothing in this case) and ultimately the willingness of these consumers to buy imported clothing. A questionnaire was subsequently developed to collect data from a sample of black and a sample of white South African respondents. An exploratory factor analysis of the data was done and the results indicated that for the samples of both black and white respondents, the original number of variables (excluding demographic variables) that drive consumer ethnocentrism could be reduced to ten. These variables were exactly the same for both sub-samples studied. The proposed theoretical model was also empirically tested by means of the structural equation modelling technique. The result of these tests was the creation of structural models for both sub-samples, illustrating all the variables and indicators of the measurement model and the structural relationships among the different variables. From the results it is clear that even though there were differences in terms of the impact of a number of antecedents on consumer ethnocentrism, the two sub-samples responded in a relatively similar way. The results also indicated that the antecedents, cultural openness, patriotism, individualism, age, income, attitude towards human rights and history of oppression, were regarded as antecedents for consumer ethnocentrism by both sub-samples. The differences confirmed were that the sample of white respondents also regarded nationalism and gender as predictors of consumer ethnocentrism. The results also revealed that black respondents seemed to be more ethnocentric than their white counterparts. From the results it seems that, due to the differences between the two sub-samples of this study, marketing strategies related to consumer ethnocentrism should not be identical for white and black South African consumers. Based on the results, a number of marketing strategies that could be implemented by both local and international marketers for the South African market are proposed.
The development of an instructional design model as a strategic enabler for sustainable competitive advantage
(Stellenbosch : Stellenbosch University, 2008-12) Le Roux, Leonie; Oosthuizen, Hein; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Business Management.
Organisations increasingly operate in an environment of continuous change and turbulence which places new demands on the choice of business and supportive strategies relevant not only to the sustainable competitive advantage (SCA) of the particular organisation, but also countries and the global nature in which they operate. A business-level strategy is to a large extent vested in intangible resources, specifically human resources strategy and capital, including the capabilities embodied in a productive and skilled workforce. In Africa, and South Africa in particular, there is a shortage of a workforce of such a nature. This is amongst others the result of past inequalities but also of shortcomings in current training practices in both the private and public sectors. One way to improve workforce output is though appropriate training aimed at increasing job-specific knowledge and the concomitant skills and productive behaviour. Changes and turbulence in the environment, therefore also create different challenges to training strategies and practices, with a shift from all-at-once to ongoing training with verifiable learning. In this regard instructional design (ID) models are deemed intrinsic to training strategy. In this dissertation an ID model within a particular contextualised situation is offered that broadens, deepens and extends existing ID models by positioning it within business-level strategy and by utilising a multidisciplinary approach pertinent to the new demands on training. To serve as a test-bed for the ID model it is implemented in a case organisation. The aim of the research is to evaluate the impact, based upon action standards, of the ID model on job-specific knowledge and productive behaviour and to provide an explanation of the internal construct relationships of the ID model. The purpose of the research is exploratory and interpretive, culminating in the single-case study tactic, wherein both quantitative and qualitative methods are applied. The case organisation is considered to be representative of a certain type of organisation with comparable characteristics. Where the existing literature supports the results (as in this instance), inductive generalisation facilitates the transferability and exportability of the ID model to other organisations. Results reveal a positive reaction to the ID model and a measurable increase in job-specific knowledge and concomitant productive behaviour. It is considered to be preferable over more traditional training practices. The relationships between the internal constructs of the ID model and improved job-specific knowledge and productive behaviour are seen to be facilitated by the combination and interplay of the components of the ID model. The contribution of this research is in providing and evaluating an ID model aimed at addressing the previous shortcomings in training and ID models and the application thereof in practice. Thus, the significance of the study lies in its extension of existing literature on ID models and specifically their contribution to sustainable competitive advantage, i.e. an academic theoretical contribution that extends the current body of knowledge. Particularly in its South African and African context, given the background of shortages in skills and productive behaviour and the need for fast-tracking the development of a competent workforce, the study is significant in that it provides guidelines for the practical development and implementation of a new ID model. The study makes recommendations to enhance both the formulation of the theoretical ID model as well as its practical implementation. It furthermore recommends extended research to explore the possibility of exporting the ID model to a broader range of private sector organisations as well as its possible transferability to public sector organisations.
Fund and manager characteristics : determinants of investment performance
(Stellenbosch : Stellenbosch University, 2008-12) Brown, Warren Gerhard Pearce; Smit, Eon v. d. M.; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Business Management.
The objective of this study is to provide a new approach to assessing fund management and to establish whether there is empirical support for this approach. The new approach will improve investors’ decision making with respect to the management and investment of their assets. We construct equity-only funds from quarterly equity holdings of unit trusts. The funds are ranked each quarter using various performance measures and segmented into winners and losers; firstly according to the median of the ranks and secondly according to quintile rankings. The funds’ rankings are examined for evidence of persistence. Secondly, a performance attribution method is introduced that identifies the static (“buy-and-hold”) portion and the trading portion of a fund. The funds are examined in terms of characteristics that distinguish between funds according to how the manager has chosen to organise (or construct) the fund. These characteristics are the static portion, the trading portion, the size of the static portion and the extent of the overlap between funds’ holdings and the large, mid and small capitalisation indices. Relationships between winners and losers (based on quartiles) and the fund characteristics are examined. Finally, the trading activities of investment managers, for their funds, are examined. This examination begins with the use of traditional measures that focus on a holistic approach to evaluating trading ability. The examination is enhanced with the introduction of a new reductionism approach, where the success of individual trades is examined. The results of the earlier performance attribution are included in the evaluation of investment managers’ abilities to add value to investors’ assets via trading activities.
The impact of fear appeal advertising on disposition formation in HIV/Aids related communication
(Stellenbosch : Stellenbosch University, 2008-12) Terblanche-Smit, Marlize; Terblanche, Nic S.; Boshoff, Christo; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Business Management.
Research to guide marketing practitioners in social issue-related communication remains underexplored. The increases in various social problems have caused practitioners to return to fear appeals as motivation to influence individuals to think and behave in a certain way. The HIV/AIDS pandemic is a major concern worldwide, as well as in South Africa, and some marketing communication campaigns do not seem to be producing the expected results. During 2007, an alarming 33.2 million people worldwide were infected with HIV. The African continent, and specifically sub-Saharan Africa, is still hardest hit by this pandemic. The high level of new HIV infections occurring daily in South Africa reflects the difficulties faced by HIV/AIDS education and prevention campaigns. Approximately 5.41 million people were living with HIV in 2006. This equates to about 11 percent of the total population and approximately 1 000 AIDS deaths occur every day. The social climate in South Africa has not been conducive to safe sexual messages, and there is a continuing need to encourage safe sexual behaviour, and awareness of the detrimental effects of HIV/AIDS. An estimated 60 percent of all new HIV/AIDS infections in South Africa occur in people between the ages of 15 and 25 years, with young women being more at risk of contracting HIV/AIDS than young men. This trend implies that the impact of the HIV/AIDS epidemic will be felt extensively in the next decade. Additionally, HIV/AIDS prevention programmes for the youth are not having the intended effect to promote partner reduction, consistent condom use and prompt treatment for sexually transmitted infections. These factors confirm that HIV/AIDS marketing communication programmes are of central importance in slowing down the spread of the disease among South African adolescents. Marketing communication is evolving to an era of tailored messages targeted at individuals and more sophisticated segmentation of target audiences. South African young adults reside in a country with diverse racial groups and cultural backgrounds. The more knowledge about their feelings and fears about HIV/AIDS become available, the more effective marketing communication can be developed. Overall marketing communication campaigns must be tailored to the specific needs of adolescents and the promotion of safer sexual behaviour should be at the core of HIV/AIDS programmes, since they are embarking on their sexual lives and are therefore open to behavioural change interventions. This study investigated whether the use of fear increases the likelihood of adopting appropriate behaviour pertaining to HIV/AIDS. Fear, attitude towards the advertisements, severity, susceptibility and efficacy were examined to ascertain the influence of fear appeals. Findings provide encouraging evidence for the persuasive power of fear appeals. Fear appeals can be a strong motivator if accompanied by high efficacy messages, to improve knowledge and to influence attitudes about HIV/AIDS. Susceptibility to the disease among adolescents also influences behaviour, and the importance of individual factors, including racial characteristics and personality, was confirmed. The empirical results of the study reveal that together with message factors like message content and media usage, the goal of changing adolescents’ sexual behaviour in the midst of the HIV/AIDS pandemic can be achieved.
The impact of strategic leadership on the operational strategy and performance of business organisations in South Africa
(Stellenbosch : University of Stellenbosch, 2010-12) Serfontein, Jacob Jacobus; Hough, Johan; University of Stellenbosch. Faculty of Economic and Management Sciences. Dept. of Business Management.
ENGLISH ABSTRACT: The turbulent and rapidly changing world, including South Africa, has created a society craving for speed and action. Future leaders, therefore, face incredible pressures to deliver immediate results, to do more with less and to manage an ever-increasing personal workload. The pace and urgency of daily demands can make it difficult to be more than the step ahead into the future. But in a world of changing conditions and priorities, leaders and individual contributors alike must be able to look beyond the ‘now’ and take a more strategic leadership approach to their work and responsibilities. Global mega-trends are leading to increasing levels of complexity, dynamism and uncertainty in the corporate environment. In an uncertain economy, organisations need effective strategies that will enable them to thrive. Traditional leadership approaches have been rendered insufficient by the rapid changes in the knowledge economy. Businesses need to practise systemic innovation in this fast-changing, knowledge-driven global business landscape in order to remain competitive. Despite heightened awareness and interest by both scholars and practitioners in the field of strategic leadership, the subject will always be an emerging field of inquiry. Furthermore, limited research has thus far been conducted on the impact of strategic leadership on the operational strategy and performance of business organisations in South Africa. A review of strategic leadership literature revealed a research gap that culminated in the following research question: “What is the impact of strategic leadership on the operational strategy and performance of business organisations in South Africa”? To address the research question stated above, a literature review on the impact of strategic leadership on the operational strategy and performance was conducted, and an empirical study was executed. The literature review emphasised the three interrelated strategic leadership constructs of action, coherence and discipline that explored the relationship between strategic leadership and the organisation’s operational strategy and performance. In this study, operational strategy includes strategic orientation as well as the operational excellence of the organisation. The factors which influence strategic orientation were identified as the organisation’s ability to create and formulate their strategy as well as the discipline of all people in the organisation to execute the strategy. Operational excellence, was influenced by product differentiation, cost management and integration. The literature review also emphasised the influence of adaptive leadership, autonomy, communication, knowledge, processes and systems, and values on self reported organisational performance which was directly related to strategic leadership. To address the research problem, empirical cross-sectional telephone surveys were conducted. The sample selected for the study was the top 200 listed organisations for 2008, as published in the Financial Mail. The key respondent was the chief executive officer (CEO), or a member of the executive team. The sample consisted of 200 organisations of which 118 valid responses were received with a response rate of 59 percent. Measurement instruments were adapted, developed and revised where necessary to ensure the reliability and validity of the data. The collected data were analysed using descriptive and inferential statistics. The findings of the study indicated that strategic leadership is directly and indirectly positively associated with operational strategy and organisational performance. It is positively associated with strategy orientation as well as operational excellence of business organisations in South Africa. Furthermore, strategic leadership can also be related to return on assets (ROA) and earnings per share (EPS). Self reported performance is also associated with higher organisational performance. Strategic leadership is unrelated to the size of the organisation, but is more likely to occur in a turbulent business environment. Product differentiation and cost management were also directly linked to strategic leadership. The most important contribution of this study is based on the testing of successful strategic leadership practices in business organisations in the South African context. Competition in the 21st century’s global economy will be complex, challenging and filled with competitive opportunities and threats. This study asserted that effective strategic leadership practices could help business organisations in South Africa to enhance their performance while competing in turbulent and unpredictable environments. Measurement instruments have also been developed, which may be used by executives, consultants and other researchers to measure these phenomena in future.
