How Internet Security Breaches Harm Market Value

Internet security in stock market was the topic in this paper. Decision-tree induction is effective for examining the factors influencing abnormal stock market returns after a public security breach announcement. Extending a previous study, the authors identify new relationships between abnormal returns and firm and attack characteristics and subject them to statistical testing.

Effects of firm and IT characteristics on the value of e-commerce initiatives: An inductive theoretical framework

We explore the theoretical foundations on how firm and IT characteristics explain the market value variations in e-commerce initiatives by examining the announcements of 946 e-commerce initiatives in the public media. Our approach combines the Event study methodology and Decision tree induction to examine the main and interaction effects of IT and firm characteristics on Cumulative Abnormal Returns (CAR). In particular, we generate complex interaction models that can guide e-commerce investment decisions so managers can know, for example, which combination of IT and firm characteristics are more likely to be viewed positively by investors. The selected study variables as well as explanation of the proposed framework are informed by innovation, resource-based view, transaction cost economics and complementarity theories. We have inductively developed a set of propositions that can be deductively tested to assess the validity of our proposed theoretical framework. Hence our study provides an initial roadmap for theory development on e-commerce and CAR.

Examining Online Banking Initiatives in Nigeria: A Value Network Approach

The central banks of several developing nations have encouraged financial institutions to provide strategic online banking services and products to remain competitive. This is in recognition of the cheaper cost of information and communication technologies (ICT) that support the delivery of such products and services. In this paper, we use a value network theoretical model to examine the electronic banking services and products provided by banks in Nigeria. We visited the websites of banks and identified the different services they provide using Southard and Siaus [24] framework. We also interviewed operations managers of these banks to validate the data collected from the websites. We discuss the implications of our findings using the value network model as a lens, and suggest appropriate strategies that will enable banks provide competitive products and services, and create value for the banks and their customers.

An Exploratory Study Of The Contextual Factors That Influence Success Of Ict Projects In Developing Nations: A Case Study Of A Telecommunications Company In Ghana

Abstract Organizations use various information and communication technologies (ICTs) to support business operations. In the developing world, ICT has promise for socio-economic development of the people. Successful project implementation is necessary in order to obtain the needed benefits from ICT endeavors. Factors that contribute to the successful implementation of ICT projects are well known. However, the implementation of ICT projects in developing countries is a more recent phenomenon that has not been well researched. In this paper we use a case study of ICT project implementation within one company in Ghana to highlight factors that underlie the implementation of ICT projects and how these factors collectively impact project success. The study shows that some of the factors identified as important in developed nations were relevant in the developing nation environment. However, the relative ranking of the importance of the factors was different between developed and developing nations. The study also identified additional factors that were relevant in the developing nation context. Our study is informed by the diffusion innovation theory, Hofstede’s cultural theory and DeLone and McLean’s IS success model. We present a framework that ties the ICT project success factors together and can serve as a guideline in ICT implementations in similar environments.

An exploratory study to examine the success of electronic banking systems implementation in a developing nation

This exploratory study examines the success of electronic banking systems implementation in a developing nation environment. We use the DeLone and McLean (D&M) Information System (IS) success model as a theoretical framework to examine the success of IS implementations in one national bank and one international bank in Ghana. Results indicate that the D&M model is only partially applicable in a developing economy environment. Specifically, only 6 of the 12 paths were found to be significant. System quality, service quality and intent to use/use influence user satisfaction.

ICT Capacity as the Investment and Use of ICT: Exploring its Antecedents in Africa

In this paper, we investigate the extent to which economic, human development endowment, political, and population conditions influence information and communication technology (ICT) capacity in African nations using ordinary least squares. We use five variables to measure ICT capacity: ICT expenditure as a percent of GDP (ICTE), ICT expenditure per capita in US dollars (ICTEP), investment in telecoms with private participation (INVTE), Internet users per 100 people (INTUS), and mobile phone subscribers per 1000 people (MOBPS). Unlike ICT adoption and diffusion that focuses on the use of ICT, ICT capacity measures public and private investments in ICT and the use of ICT. The results indicate that ICT capacity of a nation increases with increased (high) corruption index. Further, ICT investment by the private sector depends mainly on human development factors and is not influenced by the perceptions of corruption about a nation. We present theoretical and practical implications of the findings for developing nations in general and African nations in particular.

Architecture for Managing Knowledge on Cybersecurity in Sub-Saharan Africa

In this paper, we present architecture for managing knowledge on cybersecurity in Sub-Saharan Africa. This architecture captures the critical contextual factors in the Sub-Saharan African region. The architecture enables the creation, storage/retrieval, transfer and application of knowledge on cybersecurity especially for home users while providing awareness and enforcement mechanisms to help home users protect themselves against cyber threats. The architecture can facilitate the building of expertise on cybersecurity among the stakeholders. The implications of the proposed architecture are presented.

A hybrid decision tree based methodology for event studies and its application to e-commerce initiative announcements

The event study methodology has been applied in various business disciplines. This methodology typically has two goals: (1) to determine whether an event such as the announcement of an e-commerce initiative in the public media leads to cumulative abnormal returns (CAR); and (2) to examine the factors that influence the observed CAR. Most studies have used parametric statistical analysis in estimating CAR and regression for achieving the second goal. In this paper, we propose a hybrid methodology that involves using nonparametric statistical analysis to obtain the first goal, and the use of Decision Tree (DT) induction as a novel approach to reach the second goal. We apply the hybrid methodology to e-commerce announcements. The use of nonparametric analysis enables us to address some of the prior concerns of event study research in the e-commerce domain with regard to the limitations of short run event windows. The use of the novel DT-based approach leads to additional insights beyond what is reported in the literature through the examination of contingency effects. Specifically, our results indicate that the impact of Governance, Customer Type and Firm Type on CAR is contingent on the innovativeness of the e-commerce initiatives. Our study makes both methodological and theoretical contributions regarding the use of DT induction and nonparametric analysis in event studies especially in situations where prior studies present mixed results and where there are concerns about return variability. We present both research and managerial implications of the findings.

Towards standardisation of E-zwich implementation: mapping SWOT analysis to management framework models approach

The Central bank of Ghana has recently supervised the implementation of E-zwich, an innovative common payment platform to unify the payment systems of all banks and other financial institutions in the country, and a biometric smartcard for secure payment of goods and services. Despite the several advantages that E-zwich promises, there are challenges that need to be addressed to enable the stakeholders receive the full benefit that the system has to offer. In this paper, we perform SWOT analysis on the implementation of the E-zwich system, and map the findings from the SWOT analysis to PPT and GTZ management frameworks models. The mapping can serve as standards to enhance the successful implementation of such systems.

An exploratory analysis of internet banking adoption using decision tree induction

Although internet banking promises several benefits to bank customers, the adoption of online banking services continue to be low especially in developing countries. Prior research has examined internet banking adoption as a classification problem with a focus on adopters and non-adopters using traditional statistical approaches. In this paper we extend the problem by including partial adopters and used decision tree induction as the analytical method. Our results on data from customers in 20 countries show that household income is the most important variable in separating those who do not adopt IB or partially adopt IB from those who fully do. Education and age are the most important variables in separating partial adopters from non-adopters. While exploratory, our results provide opportunities for further theory development on internet banking adoption while practically contributing to discussions on how practitioners can develop specific strategies to targeted customers to become fully adopters of online banking services.
