Accounting scandals and concerns about the quality of financial statements have led to many calls for improved audit committee effectiveness. Prior research indicates that audit committee independence is positively related to effective oversight of the financial reporting process. Unfortunately, prior research has not provided an answer as to how much independence on the audit committee is enough. This is an important unanswered question because while Section 301 of the Sarbanes-Oxley Act of 2002 (SOX) currently requires all listed companies to maintain an audit committee that is 100% independent there has been much debate regarding easing the SOX requirements for smaller and foreign companies. In this paper we examine whether the regulatory requirements of a completely independent audit committee are necessary to obtain the monitoring benefits related to audit committee independence that have been documented in prior literature. Our results suggest that the benefits of audit committee independence are consistently achieved only when the audit committee is completely independent. These results provide support for the SOX requirement of 100% independent audit committees.  相似文献

Forecasting performance of December corn and November soybean futures contracts during the previous spring was evaluated using the commonly specified price-level and percent-change models. These models invoke different assumptions regarding stationarity. Using Stein's analytical framework, results for the price-level model suggest avoidable social loss existed in the soybean market since 1973, because November futures provided biased forecasts. Regression R2s for both corn and soybeans declined substantially between 1952–1972 and 1973–1997, suggesting total social loss increased. By contrast, results from the percent-change model suggest only unavoidable social loss existed in the corn and soybean markets, because the futures provided unbiased forecasts. R2 increased for corn but declined for soybeans, suggesting unavoidable social loss declined for corn, but increased for soybeans. The important, conflicting nature of the results from the two models underscores the importance of examining alternative model specifications when evaluating price forecasting performance. © 1999 John Wiley & Sons, Inc.

The demographic imbalance is aggravating, and by 2060 the old-age dependency ratio will double to approximately 70%. This development has consequences for the state pension system: growing contribution rates to social security coupled with lower pension levels, but at the same time a higher retirement age. The German pension scheme is mandatory for all wage and salary earners, but since 2001, no reasonable indicator for measuring the pension level exists any more. As a consequence of this, old-age pension has lost its traditional function as a replacement for earnings. The recent pension reforms have dropped the pension level sharply. Further reductions have been announced with the consequence of increasing old age poverty. Against this background it is proposed to raise the pension level so that the pensioners can maintain their standard of living. But any pension reform involves issues of distribution between and often also within generations, which cannot be addressed without explicit equity criteria. Some authors consider the past reforms as a mistake, others suggest adjustments.  相似文献

Despite significant scholarly debate about knowledge production in the management discipline through the peer-review journal processes, there is minimal discussion about the ethical treatment of the research subject in these publication processes. In contrast, the ethical scrutiny of management research processes within research institutions is often highly formalized and very focused on the protection of research participants. Hence, the question arises of how management publication processes should best account for the interests of the research subject, both in the narrow sense of specific research participants and in the broader understanding of the subject of the research. This question is particularly pertinent in light of significant codification of research ethics within academic institutions, and increasing self-reflection within the management discipline about the “good” of management research and education. Findings from a survey and interviews with management journal editors (and others involved in journal publication) reveal a complex scenario; many editors believe that a formalized requirement within the journal publication process may have detrimental outcomes and, in fact, diminish the ethical integrity of management scholarship. Building on these findings, this paper argues that ethical concern for the research subject merely in terms of institutional rule compliance and avoidance of harm to individual participants is insufficient, and calls for explicitly positive engagement with both the individual and the collective subject of management research should receive due ethical consideration. An alternative model involving reflexive ethical consideration of research subjects across the publication process—with implications for role of authors, reviewers, editors, and research subjects—is outlined.  相似文献

Modality analysis is a text analysis methodology that affords comparisons of how people from distinct cultural contexts differ in their accounts of why one or more of their numbers find specific activities possible, impossible, inevitable, or contingent. The technique is built around a two-part semantic grammar, the application of which involves the identification of modal clauses in texts, the classification of these clauses according to their modal forms, and the identification of rationales associated with the clauses’ modalities. We show that with sufficient training the method affords high interrater agreement. After providing a few tips on data-collection strategies, results are presented from a modality analysis of editorials sampled from the Arab newspaper, Al Riyadh, and the Hindi newspaper, Hindustan. The analysis illustrates how modal expressions can be used in locating well-known (e.g., Islamic and Hindu) cultural characteristics from among the vast quantities of discourse that societies continuously generate.  相似文献

Despite wide recognition of the central role of knowledge and its transfer, extant research has focused much on some important aspects of knowledge transfer and paid little attention to others. We focus on two underexplored issues in the knowledge transfer literature, namely: (a) compatibility of new knowledge with recipients’ needs, interpretations of its past experiences and its existing norms, and (b) organizational unlearning, which moderates the relationship between compatibility and extent of successful knowledge transfer. We examine different types and dimensions of knowledge compatibility and organizational unlearning within our proposed knowledge transfer process framework. We situate our discussion primarily within knowledge transfer in cross-border mergers and acquisitions. Based on the proposed model, we also offer propositions future research can test.  相似文献

The importance of the industrialized countries – including the USA – for world production has been declining for a long time. By contrast, China’s share in particular has increased significantly. Nevertheless, the US dollar has largely fulfilled the criteria for a leading currency function so far, even if this is increasingly criticised due to the protectionist rhetoric of the US. Accordingly, central banks worldwide hold their reserves primarily in US dollars and transactions are largely conducted in US currency. This position brings great advantages–such as making it easier for the US to monitor and enforce sanctions, among other things–and therefore great incentives for the US to maintain its position as the leading currency. Whether other currencies, especially the renminbi, will be able to fulfil the lead currency function is questionable. Similarly, it does not seem realistic that market participants will be able to engage in a global currency.  相似文献

Media communication has become a crucial part of crisis communications due to the rapid dissemination of information along with its immense impact on consumers and other stakeholders. Based on a structured content analysis of electronic media reports on restaurant-associated food safety crises from 1993 to 2015, this study examined media reporting patterns focusing on three elements: instructing information, crisis response strategies, and stakeholders. This study also identified the effect of situational factors (severity of risk and crisis type) on the media reporting patterns using Chi-square tests. The results indicated that restaurant firms were more likely to use proactive than passive response strategies, and identified primary stakeholders during a food safety crisis such as regulatory agencies, victims, and customers. Finally, two situational factors were found to influence the pattern of media reporting. The media reporting patterns were found to vary by risk severity and crisis type.  相似文献

Aims: To develop a budget impact model (BIM) for estimating the financial impact of formulary adoption and uptake of calcipotriene and betamethasone dipropionate (C/BD) foam (0.005%/0.064%) on the costs of biologics for treating moderate-to-severe psoriasis vulgaris in a hypothetical US healthcare plan with 1 million members.

Methods: This BIM incorporated epidemiologic data, market uptake assumptions, and drug utilization costs, simulating the treatment mix for patients who are candidates for biologics before (Scenario #1) and after (Scenario #2) the introduction of C/BD foam. Predicted outcomes were expressed in terms of the annual cost of treatment (COT) and the COT per member per month (PMPM).

Results: At year 1, C/BD foam had the lowest per-patient cost ($9,913) necessary to achieve a Psoriasis Area and Severity Index (PASI)-75 response compared with etanercept ($73,773), adalimumab ($92,871), infliximab ($34,048), ustekinumab ($83,975), secukinumab ($113,858), apremilast ($47,960), and ixekizumab ($62,707). Following addition of C/BD foam to the formulary, the annual COT for moderate-to-severe psoriasis would decrease by $36,112,572 (17.91%, from $201,621,219 to $165,508,647). The COT PMPM is expected to decrease by $3.00 (17.86%, from $16.80 to $13.80).

Limitations: Drug costs were based on Medi-Span reference pricing (January 21, 2016); differences in treatment costs for drug administration, laboratory monitoring, or adverse events were not accounted for. Potentially confounding were the definition of “moderate-to-severe” and the heterogeneous efficacy data. The per-patient cost for PASI-75 response at year 1 was estimated from short-term efficacy data for C/BD foam and apremilast only.

Conclusions: The introduction of C/BD foam is expected to decrease the annual COT for moderate-to-severe psoriasis treatable with biologics by $36,112,572 for a hypothetical US healthcare plan with 1 million plan members, and to lower the COT PMPM by $3.00.  相似文献
