Abstract:   The microstructure literature models the mechanisms through which fundamental information is incorporated into market prices. This paper extends previous models by endogenising information production and analysing incentives for costly information production. In contrast to the existing literature, increasing the number of informed traders can result in reduced price informativeness. When prices have an allocative role this has welfare consequences: the regulatory implications of a dichotomy between private and public incentives for information gathering are discussed.  相似文献

This article reports results of a 1993 questionnaire survey of how UK companies have been innovating technologically in response to environmental pressures. The survey sought to identify factors stimulating UK firms to innovate more environmentally friendly products and processes, and to investigate the changes in R&D activity they have undertaken to facilitate such innovation. In devising the questionnaire and interpreting the results, we have been strongly influenced by the theoretical frameworks developed over the past 15 years which describe technological developments in terms of ‘selection environments’ and ‘technological trajectories’. Useful though such frameworks are, we conclude that they need to be supplemented by concepts derived from the sociology of technology and from studies of corporate strategies.  相似文献

A conceptual framework of anonymity in Group Support Systems   总被引:2,自引:2,他引:0  
As the development and use of automated systems for collaborative work grows, the need for a better understanding of these systems becomes more important. Our focus is on one type of system, a Group Support System (GSS) and, in particular, on one important aspect of a GSS—anonymity. A conceptual framework for the study of anonymity in a GSS is presented, which describes the general classes of variables and their relationships. These variables include the factors that influence anonymity in a GSS, types of anonymity, and the effects of anonymity on a message sender, receiver, group process, and outcome. Each of these variables is discussed with working propositions presented for important group process and outcome measures. The objectives of this article are to highlight the importance and complexity of anonymity, to act as a guide for empirical investigations of anonymity, and to influence future GSS development and use.  相似文献

This paper examines moral issues concerning a firm's use of genetic information about a prospective employee's predisposition to contract occupational and other illnesses. It critically reviews leading social construction literature on genetic abnormality and genetic screening, and it examines the relevance of arguments from justice and meritocratic principles. It concludes that there is a strong moral presumption against genetic screening in employment.Alan Strudler is Research Scholar at the Institute for Philosophy and Public Policy at the University of Maryland, College Park.

Empirical studies provide compelling evidence that economic agents do not adopt the complete range of energy-efficient technologies that are cost-effective under prevailing prices and market conditions. Analysts commonly attribute this anomaly to the use of high discount rates in energy-related decisions-an interpretation that is difficult to reconcile with standard models of rational choice. This paper recasts the controversy from the perspective of economic theory and finds that market failures related to asymmetric information, bounded rationality, and transaction costs are major contributors to the so-called "efficiency gap."  相似文献

At present, our society and its social security system are not prepared to cope with the challenges resulting from the continuous increase of life expectancy. The traditional concept of disease has to be modified for serving the special needs of the elderly. The optimistic compression of disease theory is an intriguing model, but lacks prove by available data. The anti-aging boom diverts the focus from the social and financial burden that will be unevitably caused by long-term care in the future. If there will not be an — up to now unforeseeable — breakthrough in research, particularly dementia will have an enormous impact on social cost which is often underestimated.  相似文献
