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

This study was undertaken to investigate the inclusion of a kosher claim in an advertisement for a familiar and unfamiliar brand of breakfast cereal. Results showed that, as hypothesized, for the familiar brand a kosher third party endorsement led to significantly more kosher attribute-related thoughts, more favorable product attitude and greater purchase intention. For the unfamiliar brand, no significant impact upon these dependent measures was observed given a kosher endorsement. Findings are interpreted from a cognitive perspective regarding the salience of the kosher attribute in a product familiarity context. Managerial implications are discussed.  相似文献

This study examines the long memory behavior in gold returns during the post-Bretton Woods period using a new rescaled range technique. Unlike the conventional rescaled range analysis, the new rescaled range analysis is robust to short-term dependence and conditional heteroscedasticity found in the gold data. Statistical results suggest that the long memory behavior in gold returns is rather unstable. When only few observations corresponding to major political events in the Middle East, together with the Hunts event, in late 1979 are omitted, little evidence of long memory can be found.  相似文献

In this research we use a continuous payment formula for duration to examine the price behavior of a fixed-rate level payment mortgage. In the case where the mortgage is held to maturity, duration increases monotonically as term-to-maturity increases, regardless of changes in the market rate of interest. In the case where the mortgage is prepaid prior to maturity, there exists a unique market interest rate below which duration is a monotonically increasing function of time of prepayment, but above which duration has a global maximum at some time of prepayment prior to the term-to-maturity.  相似文献

Considering the characteristics of banks that do and do not report interest rate swaps, the long-term interest rate exposure of a bank and the likelihood and extent of swap market participation are found to be positively related. Key to the finding is the inclusion of variables related to the provision of swap market intermediary services, which significantly explain both the likelihood of swap market participation and the notional value of outstanding swaps. The results suggest that the likelihood and extent of swap market participation by low-capitalized banks is less than for other banks.  相似文献
