This paper explores the implications of e‐commerce transactions and the lack of consumer protection regulation on consumer educators and curricula. The discussion is divided into five sections: conceptualizing e‐commerce; the juggernaut of e‐commerce; consumer education defined, especially consumer protection in the electronic market‐place; the Organization for Economic Co‐operation and Development (OECD) 1998 Ottawa conference on electronic commerce; and the implications of this fluid market and policy context on consumer educators. Empowerment of the consumer, the ultimate objective of consumer education, is a total challenge in the global electronic market‐place, but a challenge that must be embraced by staying informed, becoming a consumer advocate, as well as educator, and remaining ever vigilant as curricula are developed for the domestic consumer transacting in an electronic global market. 相似文献

Personalization is a key component of an interactive marketing strategy. Its purpose is to adapt a standardized product or service to an individual customer's needs. The goal is to create profit for the producer and increased value for the consumer. This goal fits nicely into traditional notions of segmentation. Applications of personalization have advanced greatly in conjunction with the Internet, since it provides an environment that is information rich and well suited to interactivity. This article reviews past research on personalization and considers some examples of personalization in practice. We discuss what we believe are key problems and directions for personalization in the future. 相似文献

Implications of Realization Uncertainty on Random Utility Models: The Case of Lottery Rationed Hunting 总被引:1,自引:0,他引:1

Conditional multinomial logit (MNL) models are often used to estimate the value of nonmarket resources under the assumption that consumer choices will be realized with certainty. The conditional MNL may not be appropriate when choices made may not be realized with certainty, such as when rationing mechanisms are used as a means of managing nonmarket resources. Two models that address this issue, developed by Boxall (1995) and Rouwendal (1989), are compared here to estimate welfare measures for moose hunting in Newfoundland. The results from these two models differ significantly from the results of a simple conditional MNL model .
Les modèles logit multinomiaux conditionnels (MNL) sont souvent utiliés pour calculer la valeur de ressources non marchandes, dans une hypothèse de départ voulant que les choir du consommateur sont assurés d'être réalisés. Ce genre de modèle peut toutefois ne pas convenir lorsque les choix fait ne sont pas assurés d'être pleinement réalisés, comme dans les cas où des mécanismes de rationnement sont imposés comme moyen de gérer ces ressources non marchandes. Nous comparons deux modèles conçus et mis au point, l'un par Boxall (1995), l'autre par Rouwendal (1989), pour estimer les mesures des effets socio-économiques d'une réglementation de la chasse de l'orignal a Terre-Neuve. Il apparaêt que ces deux modèles aboutissent à des résultats significativement différents de ceux obtenus par un modèle MNL conditionnet simple . 相似文献

The article describes how the external forces of Japanese culture, industrial organization, and government intervention support managerial and organizational learning. It provides an overview of the culturally explicit philosophies that govern and stimulate learning in Japan, then explains how these philosophies are exhibited in Japanese management practice today. A model is presented which demonstrates the relationships among external forces, philosophical origins, management practice, and managerial and organizational learning. The conclusion is that managerial and organizational learning constitute one of Japan's most valuable competitive advantages. © 1998 John Wiley & Sons, Inc. 相似文献

This paper analyzes the decision of mid-career personnel to voluntarily leave the U.S. military in response to a financial incentive program. A model of the separation decision is tested using data on Navy and Air Force enlisted personnel who were targeted for the buyout in 1992. Two alternative estimates are provided, one from a fixed effects model and one from a structural, annualized cost of leaving model. Our basic results indicate the financial incentive had a modest effect in inducing additional quits. The impact of the separation bonus, however, was much larger for occupations facing a threat of involuntary layoff. 相似文献

This paper explores bond immunization for additive term structure models. This class of term structures contains many models that are commonly used in the duration and immunization literature. We establish the necessary and sufficient conditions for immunization and prove the existence of a bond portfolio that satisfies the immunization condition. Based upon the immunization condition, we develop a general definition of duration that applies to any additives term structure model. 相似文献

Two possible patterns for the organization of advanced technological education can be detected in Britain since 1945. The dominant assumption links training closely to fundamental advances in the sciences, and centralizes teaching at a small number of specialist institutions. The influence of such a policy is seen in the decisions which limited the numbers of Colleges of Advanced Technology in 1956, and in the continuing pressure from science advisory circles for the establishment of a few high-level training centres. The alternative pattern seeks to respond to the diverse range of industrial demands at local level in a decentralized system of technological training whose goals and standards are readily influenced by the technical and manpower demands of neighbouring industry. Neglect of this alternative can be explained from persistent trends in British professional organization, but the economic consequences may well be momentous. 相似文献
