E‐government adoption in ASEAN: the case of Cambodia

Purpose – The purpose of this paper is to examine the factors that influence e‐government adoption in Cambodia as one of the Association of Southeast Asian Nations (ASEAN) member states.Design/methodology/approach – This study uses the technology acceptance model (TAM), the extended TAM (TAM2), the diffusion of innovations (DOI) theory, and trust to build a parsimonious yet comprehensive model of user adoption of e‐government. The authors test the model with an empirical study. Data are collected from a total of 112 public officers in 12 ministries in Cambodia. The research model is then assessed with multiple regression analyses.Findings – The findings in this study show that the determinants of the research model (perceived usefulness, relative advantage, and trust) are support. At the same time, the important determinants of perceived usefulness include image and output quality.Practical implications – The study would help government policy decision makers design and implement policies and strategies t...

E‐government adoption in Cambodia: a partial least squares approach

Purpose – The purpose of this paper is to investigate factors influencing end‐user acceptance and use of government administration information system (GAIS).Design/methodology/approach – A conceptual structural model of end‐user acceptance and use of the GAIS was developed with technology acceptance model as a theoretical background and tested using a structural equation modeling with partial least squares (PLS) approach on a data collected from a survey among 112 public officers in 12 ministries in Cambodia.Findings – The results indicate that the factors influencing end‐user adoption of the GAIS are significantly affected by perceived usefulness, relative advantage, and trust. Perceived usefulness of the GAIS is directly affected by subjective norm, image, output quality, and perceived ease of use.Practical implications – The results are of practical significance to all those interested in this area, mainly the government policy makers and practitioners in Cambodias public services.Originality/value – ...

Strategic Management of Cloud Computing Services: Focusing on Consumer Adoption Behavior

The emergence of cloud computing services has led to an increased interest in the technology among the general public and enterprises marketing these services. Although there is a need for studies with a managerial relevance for this emerging market, the lack of market analysis hampers such investigations. Therefore, this study focuses on the end-user market for cloud computing in Korea. We conduct a quantitative analysis to show consumer adoption behavior for these services, particularly infrastructure as a service (IaaS). Bayesian mixed logit model and the multivariate probit model are used to analyze the data collected by a conjoint survey. From this analysis, we find that the service fee and stability are the most critical adoption factors. We also present an analysis on the relationship between terminal devices and IaaS, classified by core attributes such as price, stability, and storage capacity. From these relationships, we find that larger storage capacity is more important for mobile devices such as laptops than desktops. Based on the results of the analysis, this study also recommends useful strategies to enable enterprise managers to focus on more appropriate service attributes, and to target suitable terminal device markets matching the features of the service.

Strategic demand forecasts for the tablet PC market using the Bayesian mixed logit model and market share simulations

Since the release of the Apple iPad and the explosion of consumer demand for tablet PCs, a number of companies are entering into the tablet PC market, creating a situation that is becoming more fiercely competitive, complex, and difficult to predict. Under the singularity of the Korean tablet PC market, into which both the iPad and Galaxy Tab (with an Android operating system) were simultaneously released, this study closely analyses consumer preferences for tablet PCs. It uses the Bayesian mixed logit model, which can reflect consumers’ heterogeneous preferences based on data collected from a conjoint method, and using the estimates of the consumer utility function with model verification, it offers forecasts for the tablet PC market under six likely situations.

An empirical analysis on consumer adoption of mobile phone and mobile content in Korea

This paper aims to empirically analyse consumer preference for mobile phone and mobile content. It is concerned with three issues: how users value the attributes of mobile phones; the effects of demographic characteristics on the adoption of mobile content; the relation between the adoption of mobile phone and mobile content. Discrete-choice model is used for analysing consumer choice data collected from the survey. The results show that touch-screen and full web browsers are preferred and the consumption pattern of mobile content is different according to individual characteristics. There are significant correlations between the adoption of mobile phone and mobile content. Mobile phone that supports full browsing has positive correlations with mobile contents. The findings suggest that mobile phone with particular feature is needed to promote use of mobile content.

Digital identity: How users value the attributes of online identifiers

Abstract This paper examines online identifiers from an economic perspective. It uses conjoint analysis survey techniques to develop empirical data on how users value the attributes of online identifiers. It is concerned in particular with three issues: (1) the degree to which identified subjects value increasing the scope of an identifier, i.e., the ability to use a single identifier to access services offered by several organizations; (2) the degree to which users’ choice may be constrained by switching costs; and (3) the value individuals place on privacy and data security relative to other attributes such as cost or scope. The survey population was located in South Korea. The results indicate that e-mail addresses dominate the world of online identifiers for ordinary consumers; that consumers highly value increased scope (e.g., single sign-on capabilities) and the security of their private data; and that switching costs are high.

Technology adoption: A conjoint analysis of consumers׳ preference on future online banking services

Abstract The importance of service delivery technology and online service adoption and usage in the banking industry has received an increased discussion in the literature in recent years. Owing to the fact that Strong online banking services are important drivers for bank performance and customer service delivery; several studies have been carried out on online banking service adoption or acceptance where services are already deployed and on the factors that influence customers׳ adoption and use or intention to use those services. However, despite the increasing discussion in the literatures, no attempt has been made to look at consumers׳ preference in terms of future online banking service adoption. This study used conjoint analysis and stated preference methods with discrete choice model to analyze the technology adoption pattern regarding consumers׳ preference for potential future online banking services in the Nigerian banking industry. The result revealed that to increase efficiency and strengthen competitiveness, banks need to promote smart and practical branded services especially self-services at the same time promote a universal adoption of e-banking system services that add entertainment or extra convenience to customers such as ease of usage including digital wallet, real-time interaction (video banking), ATMs integrated with smart phones, website customization, biometric services, and digital currency. These services can contribute to an increasing adoption of online services.

A practical approach for beginning the process of technology roadmapping

The study addresses the need for a robust yet practical technology roadmapping method that considers four major factors: input from consumers who use the technology; input from engineers who develop the technology; the technological gap between the roadmapped technology and competing technologies; and future changes in consumer preferences. The proposed method begins by using conjoint analysis of survey-derived consumer data to assess consumer requirements. Expert opinion is elicited regarding the relative importance of engineering characteristics, and any technological gaps are assessed. Quality function deployment is used to interconnect the results. The roadmapping method is applied to power line communications.

Using stated-preference data to measure the inconvenience cost of spam among Korean E-mail users

E-mail is an efficient communication tool, but at the same time it is an efficient vehicle for Internet pollution in the form of spam—unsolicited, bulk e-mailings. Spam is a global phenomenon, and debate about possible means of controlling it is lively. Spammers impose a negative externality on users. The volume of spam-type e-mail sent is above the social optimum and thus produces dead-weight. To solve the spam problem and evaluate spam-control measures, one needs to measure the disutility experienced by e-mail users who receive spam. The current study employs conjoint analysis of stated-preference data to estimate e-mail users’ overall inconvenience cost attributable to spam. The results show the inconvenience cost of spam to be about 3.067 won (US
