This article examines innovation in the securities industry with the central objective of identifying factors that separate innovators from non-innovators. Akira Iwamura and Vijay Jog report results based on their survey of corporate finance vice presidents or CEO's of 43 investment houses from around the world. They conclude that innovative companies seem to be larger and have a well-defined strategy, with management defining the focus of the business. In addition, the firms have developed better communication channels, both internally and with their customers. Yet, the most significant difference that separates innovators from non-innovators is their management of the idea generation process, including concept generation and management's support. Innovators tend to approach idea generation in the following ways: they employ a variety of idea sources, both internal and external; they assign a specific person or group to be in charge of developing new ideas; they encourage employees at all levels to generate new ideas; they use a variety of innovative techniques to stimulate creativity; they reward their employees by non-monetary means; and they encourage group-level participation in evaluation decisions. 相似文献

If a tax on energy affects the demand for a nondurable good, the stock of a durable good, and the proportion of the energy consumption per unit of service of the durable good, an integrated approach for investigating consumer demand for durables and nondurables is required. The purpose of this paper is to employ the concept of a variable expenditure function with quasi-fixed durable goods as arguments in order to derive a demand system for nondurable goods in prices of the nondurables, in the stocks of durables, and in variable expenditure. From the envelope condition desired stocks of durables can be calculated and investment demand for durables can be determined. For an application we choose a variable expenditure function based on the almost ideal demand specification, and evaluate alternative environmental policy measures using the equivalent variation for comparing the welfare effects. 相似文献

Abstract. A recent article in this journal (Hsieh, Ferris, and Chen, 1990) presents evidence demonstrating that financially distressed firms that terminate overfunded pension plans experience significantly positive abnormal returns, while nondistressed terminating firms experience returns not different from zero. The article concludes from this evidence that the market regards the property rights to excess assets as residing fully with the sponsoring firm prior to termination, particularly when the sponsoring firm is not financially distressed. Accordingly, the reporting requirements of Statement of Financial Accounting Standards (SFAS) No. 88, which require immediate recognition of gains resulting from termination, are inconsistent with the market's view of the ownership rights to excess plan assets. Similarly, the article suggests that the excise tax imposed on asset reversions is “punitive” because property rights to fund assets resided with the company prior to termination. This paper questions three aspects of the Hsieh, Ferris, and Chen article: (1) the plausibility of the theory explaining differential reaction to the announcement to terminate for distressed and nondistressed firms; (2) the effect of the distressed/nondistressed classification criteria, event date specification, and event window length on the results; and (3) the appropriateness of using the empirical results, if reliable, to evaluate accounting treatment or federal tax policy. Résumé. Dans un récent article paru dans cette même publication, Hsieh, Ferris et Chen (1990) soumettaient des faits démontrant que les entreprises en difficulté financière qui mettent fin à un régime de retraite surprovisionné enregistrent des rendements anormaux positifs importants, tandis que les entreprises qui mettent fin à un régime de retraite sans être en difficulté financière enregistrent des rendements qui ne sont pas différents de zéro. De là, les auteurs concluaient que le marché estime que les droits à l'excédent d'actif appartiennent exclusivement à l'entreprise responsable du régime avant la cessation, en particulier lorsque cette dernière n'est pas en difficulté financière. Par conséquent, les exigences de la norme SFAS No. 88 en matière d'information à fournir, qui prévoient la constatation immédiate du produit de la cessation du régime, ne sont pas conformes à la façon de voir du marché relativement aux droits à l'excédent d'actif du régime. De la même façon, selon les auteurs, la taxe d'accise imposée en cas de retour de l'actif est “punitive”, étant donné que les droits à l'actif du régime appartenaient à l'entreprise avant la cessation du régime. Les auteurs s'interrogent ici sur trois aspects de l'article de Hsieh, Ferris, et Chen: 1) la pertinence de la théorie expliquant la réaction marginale à l'annonce de la cessation d'un régime pour les entreprise qui sont en difficulté financière et celles qui ne le sont pas; 2) l'incidence sur les résultats des critères permettant de classer les entreprises comme étant en difficulté financière ou ne l‘étant pas, de la précision de la date de l’événement et de la longueur de la période pré-post relative à l‘événement; et 3) l'opportunité de l'utilisation des résultats empiriques, s'ils sont fiables, pour évaluer le traitement comptable ou la politique fiscale fédérale. 相似文献

Statement of Financial Accounting Standards (SFAS) No. 96, “Accounting for Income Taxes,” issued by the Financial Accounting Standards Board (FASB) in December 1987 changed accounting for income tax recognition and accrual. The original deadline for implementation of SFAS No. 96 was December 15, 1988, and earlier adoption was encouraged. This study examines empirically the stock price impact of four pertinent announcement dates regarding SFAS No. 96 for 19 banks that adopted the statement in late 1987 and early 1988. Our results suggest that these early bank adopters have different characteristics from other banks that cause them to benefit from the changes in accounting for deferred taxes and explain their voluntary adoption of the standard. 相似文献

Abstract. We experimentally investigate the effects of a mandatory increase in education on the market for professional labor services when several service qualities are assumed to exist. We show that when suppliers have insufficient incentives to offer high-quality services in a free market, an increase in mandatory education can improve the coordination of supplier decisions and increase efficiency. If suppliers voluntarily provide a sufficient quantity of high-quality services, an education constraint can have the opposite effect. In both instances, however, an increase in the mandatory level of education can be expected to reduce the price of high-quality services while increasing the price of lower service qualities. Résumé. Les auteurs ont procédé à une analyse expérimentale des conséquences qu'aurait une hausse imposée du niveau d'études sur le marché des services professionnels, si l'on suppose l'existence de plusieurs qualités de services. L'analyse démontre que lorsque les stimulants sont insuffisants pour inciter les fournisseurs à offrir des services professionnels de qualité supérieure dans un marché libre, une hausse imposée du niveau d'études peut améliorer la coordination des décisions des fournisseurs et augmenter l'efficience. Si toutefois les fournisseurs offrent de leur propre chef une quantité suffisante de services de qualité supérieure, le fait d'imposer un niveau d'études supérieur peut avoir l'effet contraire. Dans les deux cas, on peut s'attendre à ce qu'une hausse du niveau d'études obligatoire réduise le prix des services de qualité supérieure tout en augmentant le prix des services de qualité plus faible. 相似文献

Great variation in nursing resource use is documented within DRGs. Much of this variation may be explained by patient severity of illness. Variance in nursing resource use within DRGs can be reduced by using a severity of illness instrument to score patients. 相似文献

An individual's tendencies in purely personal relationships seem to lead to related tendencies in consumer relationships. The following article presents a study that illustrates how individual differences in personal relationship attachment style can be used to predict the likely success of consumer relationships. In addition, it illustrates how the success of consumption versus nonconsumption relationships can be explained by the effect of attachment style on the individual's perception of qualities of the relationship. © 2006 Wiley Periodicals, Inc. 相似文献
