By most accounts, the Internet and related advances in information technology significantly affect financial services in general and insurance markets and institutions in particular. Coupled with other important trends such as globalization and regulatory reform, these changes are forcing far‐reaching changes upon the insurance industry and making it more competitive. This article focuses specifically on the implications of the Internet for insurance markets and institutions. The conventional wisdom that the Internet constitutes a sufficient condition for the disintermediation of traditional insurance distribution networks is called into question. To the extent that the Internet reduces transaction costs, it will create opportunities for new intermediaries as well as for existing ones. It will also influence product design, in some cases making it economically attractive to unbundle and repackage various forms of coverage. By removing entry barriers and reducing insurance costs, the Internet will also provide a private market solution to a major insurance regulatory concern—enhancing insurance affordability and availability.  相似文献

The purpose of this paper is to examine the various guidelines presented in the literature for instituting an ethics curriculum and to empirically study their effectiveness. Three questions are addressed concerning the trainability of ethics material and the proper integration and implementation of an ethics curriculum. An empirical study then tested the effect of ethics training on moral awareness and reasoning. The sample consisted of two business classes, one exposed to additional ethics curriculum (experimental), and one not exposed (control). For the experimental group, ethics exercises and discussion relevant to each topic were completed. Findings suggested gender differences such that, relative to other groups, women in the experimental group showed significantly improved moral awareness and decision-making processes. An explanation of the underlying cognitive processes is presented to explain the gender effect.  相似文献

This study examines the impact of Regulation Fair Disclosure (FD) on liquidity, information asymmetry, and institutional and retail investors trading behavior. Our main findings suggest three conclusions. First, Regulation FD has been effective in improving liquidity and in decreasing the level of information asymmetry. Second, retail trading activity increases dramatically after earnings announcements but there is a significant decline in institutional trading surrounding earnings announcements, particularly in the pre‐announcement period. Last, the decline in information asymmetry around earnings announcements is closely associated with a lower participation rate in the pre‐announcement period and more active trading of retail investors after earnings releases.  相似文献

In two consumer studies, discrete choice surveys were administered both by telephone and by traditional pencil and paper methods. Study participants responded to discrete choice surveys concerning pizza restaurants in the first study and fast food restaurants in the second. Neither aggregate level estimated utilities for the pizza restaurants, nor market shares for the fast food restaurants differed by method of administration. The results indicate that discrete choice surveys can be successfully administered by telephone. He received his Ph.D. in marketing from the University of Texas at Dallas.

Hypotheses which relate top-level managers' age, years of company and industry service, and education to strategic change are studied with a sample of 855 managers from 27 railroads. Results generally support hypotheses that younger managers and those with less experience are more likely to alter their strategies with changing environmental conditions.  相似文献
