Diffusion in computing networks: the case of BITNET

Abstract: Using BITNET as a model, the author examines the adoption pattern of computing networks from the perspectives of innovation diffusion theory and economics.

An Integrative Model of Information Systems Spending Growth

Abstract: This paper develops a model of the growth of information systems expenditures in the United States. The model incorporates two major factors that influence the rate and pattern of spending growth—the diffusion of technological innovation and the effect of price on the demand for computing. Traditional studies have focused on the role of innovation while ignoring the effects of price on the growth process. We show that while information systems expenses initially grew following an S-curve, more recent growth has converged to an exponential pattern. These patterns are consistent with our integrative price-adjusted S-curve growth model.

Government as the driving force toward the information society: National computer policy in Singapore

Abstract: In an attempt to make Singapore an economic power in the post‐industrial information era, the Singaporean government is implementing a series of national computer plans designed to farther the country's efforts to move up the value‐added chain by driving information technology into all sectors of society, these plans can be divided into three distinct phases with the goal of the first phase to computerize the government sector; the goal of the second phase to computerize the country; and the goal of the third phase to turn Singapore into an information society with global connections. In looking at IT (information technology) policy for Singapore, we see that the government has had a high level of involvement in the computerization and informatization of Singapore. The Singaporean government has taken a large participatory role and a smaller but significant regulatory and coordinating role in the development and diffusion of information technology throughout the country. While production and use ...

Institutions and the international diffusion of information technolog

Abstract: The production and use of information technology (IT) in developed countries is wcll established and growing at a rapid pace. Newly industrializing countries are adopting both IT production and use as national goals. Developing countries are beginning to formulate plans to do the same. The institutional role in the international diffusion of IT is not well understood, but it is clear from the literature on innovation that the institutional role is critical. The paper makes four points. First, a traditional and fairly rigorous way of thinking about innovations the economic perspective deriving from Schumpeter and Hicks has been shown by studies from economic history and sociology/communications of innovation to be inadequate for explaining the dynamics of innovative change. The missing element is understanding of differential roles played by institutions. Second, among those promoting the need for institutional intervention there has been a debate about whether innovation is primarily supply-pushed or demand-pulled. The answer to the question has important institutional implications. The evidence, again mostly from economic history, shows it to be both, in iterative fashion. Thus institutions can intervene meaningfully on both sides. Third, there are two major forms of institutional intervention: influence and regulation. The possible intervention actions of institutions can be encompassed by a 2 x 2 matrix with supply-push and demand-pull on one dimension and influence and regulation on the other. Finally, if government wants to intervene, there are six classes of roles that might be pursued to affect innovation.
