Most purchasing professionals generally agree that the acceptance of significant gratuities is inappropriate and should be discouraged. Managers need effective methods of monitoring and controlling such activities. This study examined the impact of certain individual and organizationally controlled variables on the acceptance of gratuities. Consequently, the study was able to identify some approaches that can be used by management for control purposes. The results indicate that formal, written policies do have a significant impact on reducing the acceptance of gratuities. However, if these policies are not also applied to sales personnel in the same organization, their impact may be diminished significantly, if not lost altogether. The engagement of upper level management in questionable activities was found to be positively related to the acceptance of gratuities by buyers and purchasing supervisors. Ironically, while it seems logical that input from purchasing personnel in the development of purchasing ethics policies should reduce the propensity to accept gratuities by department personnel, the study produced no evidence that supported this conclusion.  相似文献

The Four C approach defines a method to assist human resource development professionals design strategic global training in a multinational environment. The method was developed from an analysis of published global HRD articles and two books. Four common elements were discovered during the review of the design and development of global HRD. Cooperation, collaboration, communication, and culture are the Four Cs that form the backbone of any global HRD organization. This approach is at the conceptual level with the mechanics of implementation left up to the HRD professional. Each section of the Four Cs presents the definition, discuss application, and summarize implementation. The opinion of the author is presented in the context of instructional system design to facilitate understanding the Four Cs.  相似文献

We examine how the Affordable Care Act's dependent coverage mandate (DCM) affected young adults' time allocation. Exploiting more accurate measures from the American Time Use Surveys, we find that the DCM reduced labor supply. The question then arises, what have these adults done with the extra time? Estimates suggest a reduction in job‐lock, as well as in the duration of the average doctor's visit, including time spent waiting and receiving care. The latter effect is consistent with substitution from emergency‐department utilization toward more routine care. Estimates suggest that the extra time has gone into socializing, and into educational and job‐search activities. (JEL I1, J2, H0)  相似文献

This study analyzes the effects of state bankruptcy asset exemptions and foreclosure laws on mortgage default and foreclosure rates across different segments of the mortgage market. We found that the effects of these legal provisions are larger for subprime than for prime mortgages and larger for adjustable rate mortgages than for fixed rate mortgages. These results demonstrate that the effect of variation in bankruptcy exemptions and foreclosure laws is most pronounced in the most risky segments of the mortgage market, which are those that have been most affected by the continuing housing slump in the United States.  相似文献

On August 21, 2000, the Singapore Exchange (SGX) adopted the call market method to open and close the market while the remainder of the day’s trading continued to rely on the continuous auction method. The call method significantly improved the price discovery process and market quality. A positive spillover effect is observed from the opening and closing calls. Day-end price manipulation also declined after the introduction of the call market method. However, the beneficial impact from the call market method is asymmetric, benefiting liquid stocks more than illiquid stocks.  相似文献

Earnings according to GAAP do a notoriously poor job of explaining the current values of the most successful high‐tech companies, which in recent years have experienced remarkable growth in revenues and market capitalizations. But if GAAP earnings fail to account for the values of such companies, are there other measures that do better? The authors address this question in two main ways. They begin by summarizing the findings of their recent study of both the operating and the stock‐market performance of 169 publicly traded tech companies (with market caps of at least $1 billion). The aim of the study was to identify which of the many indicators of corporate operating performance—including growth in revenues, EBITDA margins, and returns on equity—have had the strongest correlation with shareholder returns over a relatively long period of time. The study's main conclusion is that investors appear to be looking for signs of neither growth nor efficiency in using capital alone, but for an optimal mix or balancing of those goals. And that mix, as the study also suggests, is captured in a cash‐flow‐based variant of “residual income” the authors call “residual cash earnings,” or RCE. In the second part of their article, the authors show how and why RCE does a much better job than reported net income or EPS of explaining the current market value of Amazon.com , one of the best‐performing tech companies in the world. Mainly by treating R&D spending as an investment of capital rather than an expense, RCE reveals the value of a company that is distinguished by both the amount and the productivity of its ongoing investment—both of which have been obscured by GAAP.  相似文献

The publicly traded Boston Celtics Limited Partnership shares provide a unique means of studying the impact of information on equity prices. The results of the Celtics’ basketball games significantly affect partnership share returns, trading volume, and volatility. Controlling for the expectedvalue of the signal using betting-market point spreads has little effect on these relations. Investors respond asymmetrically to wins and losses, and playoff games have a larger impact on returns than regular-season games. Opening prices do not fully reflect game results, consistent with previous findings that significant volatility is caused by traders acting on private information.  相似文献
