An examination of the effects of self-regulatory focus on the perception of the media richness: the case of email

Communication is a key element in organizations’ business success. The media richness theory and the channel expansion theory are two of the most influential theories regarding the selection and use of communication media in organizations; however, literature has focused little on the effects of self-regulation by managers and employees in these theories. To analyze these topics, this study develops an empirical investigation by gathering data from 600 managers and employees using a questionnaire. The results suggest that the perception of media richness is positively affected when the individual shows a promotion focus or strategy.Peer ReviewedPostprint (author’s final draft

Evolution of the knowledge economy: a historical perspective with an application to the case of Europe

The goal of the article is to explore the evolution of original concept of knowledge economy based on science intensive production sectors toward service type economies which significantly changed the role of scientific research and technological innovation for economic growth. The paper argues that this transition is due not only to the structural changes in global production, but the theoretical evolution and aradigmatic shift of the concept of “knowledge economy” in general and “knowledge” in particular has played a significant role. The paper examines the different interpretation of knowledge within new types of intangible economies (e.g., new/Internet, weightless, service, creative, cultural economies) where knowledge is perceived to be generated not as a product of scientific research but as a service or creative activity and critically examined the role of scientific research in a service led knowledge economy. Additionally the paper argue how these phenomena, which marked the global economy in the last decades, enable the transition of the standard concept of knowledge economy originated from industrial production and manufacturing to a knowledge economy equalized with various types of expanding intangible economies, primarily those based on service and creative industries

Economic Analysis of Knowledge: The History of Thought and the Central Themes

Following the development of knowledge economies, there has been a rapid expansion of economic analysis of knowledge, both in the context of technological knowledge in particular and the decision theory in general. This paper surveys this literature by identifying the main themes and contributions and outlines the future prospects of the discipline. The wide scope of knowledge related questions in terms of applicability and alternative approaches has led to the fragmentation of research. Nevertheless, one can identify a continuing tradition which analyses various aspects of the generation, dissemination and use of knowledge in the economy

Resolving the productivity paradox

Solow [R. Solow, We'd Better Watch out, New York Times Book Review, 1987, p. 36] made the statement that 'we see computers everywhere except in the productivity statistics'. This has come to be known as the "productivity paradox". Whether this is in fact a paradox or a direct implication of the diffusion of technical change is the focus of this paper. In particular, the implications of two different theoretical treatments of technology diffusion in an economy are considered; the traditional model of [R. Solow, A contribution to the theory of economic growth, Q. J. Econ., 70 (1956) 65-94] and the alternative view of [R.G. Lipsey, K.I. Carlaw, C.T. Bekar, Economic Transformations: General Purpose Technologies and Long Term Economic Growth, Oxford University Press, Oxford, 2005]. These two distinct views articulate two general empirically testable hypotheses that are captured in a number of specific tests including measures of the diffusion of information and communication technologies (ICT). Although weak, the evidence supports the view of [R.G. Lipsey, K.I. Carlaw, C.T. Bekar, Economic Transformations: General Purpose Technologies and Long Term Economic Growth, Oxford University Press, Oxford, 2005]. © 2008 IMACS

Is there still a productivity paradox? two methods for a transatlantic comparison

Economic activity accelerated in the United States, in the second part of the cycle, after 1995, within an environment of decreasing inflation. France has followed a qualitatively similar path since 1997, also clearly suggesting the effects of a positive supply shock. The spread of new information and communication technologies (NICT) partly explains these singular events. On one hand, a calculation of contributions to output growth suggests that they would explain about half of the increase in activity in the United States and one-fifth in France. On the other hand, a trend/cycle decomposition reveals that the structural acceleration in output and productivity gains in the United States are very much restricted to industries producing NICT and there is a rather small break in productivity gains. In France, where differences between sectors are not so clear-cut, the diffusion of NICT has been accompanied by a slowdown in trends in productivity gains. In both cases, there is little room left for the effects of the diffusion of technical progress associated with NICT.New economy, Growth, Productivity paradox, Trend/cycle decomposition,
