Information Technology Adoption Across Time: A Cross-Sectional Comparison of Pre-Adoption and Post-Adoption Beliefs
The process of information technology adoption and use is critical to deriving the benefits of information technology. Yet from a conceptual standpoint, few empirical studies have made a distinction between individuals' pre-adoption and post-adoption (continued use) beliefs and attitudes. This distinction is crucial in understanding and managing this process over time. The current study combines innovation diffusion and attitude theories in a theoretical framework to examine differences in pre-adoption and post-adoption beliefs and attitudes. The examination of Windows technology in a single organization indicates that users and potential adopters of information technology differ on their determinants of behavioral intention, attitude, and subjective norm. Potential adopter intention to adopt is solely determined by normative pressures, whereas user intention is solely determined by attitude. In addition, potential adopters base their attitude on a richer set of innovation characteristics than users. Whereas pre-adoption attitude is based on perceptions of usefulness, ease-of-use, result demonstrability, visibility, and trialability, post-adoption attitude is only based on instrumentality beliefs of usefulness and perceptions of image enhancements.
Value-based Adoption of Mobile Internet: An empirical investigation
This study examines the adoption of Mobile Internet (M-Internet) as a new Information and Communication Technology (ICT) from the value perspective. M-Internet is a fast growing enabling technology for Mobile Commerce. However, despite its phenomenal growth and although M-Internet essentially provides the same services as stationary Internet, its adoption rate in many countries is very low compared to that of stationary Internet. The well-known Technology Adoption Model (TAM) has been used for explaining the adoption of traditional technologies. Most adopters and users of traditional technologies (e.g., spreadsheet, word processor) are employees in an organizational setting who use the technology for work purposes, and the cost of mandatory adoption and usage is borne by the organization. In contrast, adopters and users of M-Internet are individuals who play the dual roles of technology user and service consumer. Most of them adopt and use it for personal purposes, and the cost of voluntary adoption and usage is borne by the individuals. Thus, the adopters of new ICT, especially M-Internet, are also consumers rather than simply technology users. By adopting the theory of consumer choice and decision making from economics and marketing research, this study develops the Value-based Adoption Model (VAM) and explains customers' M-Internet adoption from the value maximization perspective. The findings demonstrate that consumers' perception of the value of M-Internet is a principal determinant of adoption intention, and the other beliefs are mediated through perceived value. The theoretical and practical implications of VAM related to M-Internet are discussed.
Social Networks and Technology Adoption in Northern Mozambique
Despite their potentially strong impact on poverty, agricultural innovations are often adopted slowly. Using a unique household dataset on sunflower adoption in Mozambique, we analyse whether and how individual adoption decisions depend upon the choices of others in the same social networks. Since farmers anticipate that they will share information with others, we expect farmers to be more likely to adopt when they know many other adopters. Dynamic considerations, however, suggest that farmers who know many adopters might strategically delay adoption to free-ride on the information gathered by others. We present empirical evidence that shows that the relationship between the probability of adoption and the number of known adopters is shaped as an inverse-U. In line with information sharing, the network effect is stronger for farmers who report discussing agriculture with others. The data contains information which is needed to ameliorate the identification issues that commonly arise in this context. In particular social networks are precisely identified, and in addition we can control for village heterogeneity and endogenous group formation.
Literature Review of Information Technology Adoption Models at Firm Level
Today, information technology (IT) is universally regarded as an essential tool in enhancing the competitiveness of the economy of a country. There is consensus that IT has significant effects on the productivity of firms. These effects will only be realized if, and when, IT are widely spread and used. It is essential to understand the determinants of IT adoption. Consequently it is necessary to know the theoretical models. There are few reviews in the literature about the comparison of IT adoption models at the individual level, and to the best of our knowledge there are even fewer at the firm level. This review will fill this gap. In this study, we review theories for adoption models at the firm level used in information systems literature and discuss two prominent models: diffusion on innovation (DOI) theory, and the technology, organization, and environment (TOE) framework. The DOI found that individual characteristics, internal characteristics of organizational structure, and external characteristics of the organization are important antecedents to organizational innovativeness. The TOE framework identifies three aspects of an enterprise's context that influence the process by which it adopts and implements a technological innovation: technological context, organizational context, and environmental context. We made a thorough analysis of the TOE framework, analysing the studies that used only this theory and the studies that combine the TOE framework with other theories such as: DOI, institutional theory, and the Iacovou, Benbasat, and Dexter model. The institutional theory helps us to understand the factors that influence the adoption of interorganizational systems (IOSs); it postulates that mimetic, coercive, and normative institutional pressures existing in an institutionalized environment may influence the organization’s predisposition toward an IT-based interorganizational system. The Iacovou, Benbasat, and Dexter model, analyses IOSs characteristics that influence firms to adopt IT innovations. It is based on three contexts: perceived benefits, organizational readiness, and external pressure. The analysis of these models takes into account the empirical literature, and the difference between independent and dependent variables. The paper also makes recommendations for future research.
Dead Or Alive? The Development, Trajectory And Future Of Technology Adoption Research
Research on individual-level technology adoption is one of the most mature streams of information systems (IS) research. In this paper, we compare the progress in the area of technology adoption with two widely-researched streams in psychology and organizational behavior: theory of planned behavior and job satisfaction. In addition to gauging the progress in technology adoption research, this allows us to identify some fruitful areas for future research. Based on our comparison, we conclude that there has been excellent progress in technology adoption research. However, as a next step, we call for research focused on interventions, contingencies, and alternative theoretical perspectives (to the largely social psychologybased technology adoption research. Also, we believe it would be important to use the comparisons discussed here as a basis to develop a framework-driven set of future research directions to guide further work in this area.
Technological Opportunism and Radical Technology Adoption: An Application to E-Business
Using the resource-based view of the firm, the authors hypothesize that differences in adoption of radical technologies among firms can be attributed to a sense-and-respond capability of firms with respect to new technologies, which is termed technological opportunism. Using survey data from senior managers in business-to-business firms, the authors study the adoption of e-business, a radical technology with the potential to alter business models. The authors first establish the distinctiveness of technological opportunism from related constructs, such as organizational innovativeness, and show that it offers a significantly better explanation of technology adoption than existing constructs do. In a follow-up survey of senior managers, the authors investigate the antecedents of technological opportunism and find that organizations can develop technological opportunism by taking specific actions such as focusing on the future, by having top management advocate new technologies, and by becoming more of an adhocracy culture and less of a hierarchy culture. The proposed technological opportunism construct can inform theory development on the relative emphasis on internal (research and development) versus external (buying, licensing) development of technologies and the complementarities in technology orientation and market orientation in the firm. The results can be used by managers who seek to develop the technological opportunism capability of their firms and by those in technology vendor firms who seek to develop segmentation strategies based on the technological opportunism capabilities of their customer firms.
Technology Adoption in the Presence of Constraints: The Case of Fertilizer Demand in Ethiopia
Using a nationally representative dataset, and information on why farmers did not purchase fertilizer, the authors estimate a double-hurdle fertilizer adoption model for Ethiopia. Access is an overriding constraint in four zones. Credit is shown to be a major supply-side constraint, suggesting that household cash resources are generally insufficient to cover fertilizer purchases. On the demand side, household size, formal education of the farmer, and the value-to-cost ratio have the largest impact on adoption and intensity of fertilizer use. The results underline the importance of increasing the availability of credit, developing labor markets, and reducing the procurement, marketing and distribution costs of fertilizer. The authors conclude that current large-scale transport, health, and education investment programs will positively impact smallholder productivity and household welfare. The price sensitivity of farmers suggests that an urea subsidy could be useful in redressing the nutrient imbalance currently observed in Ethiopia.
