The proposed method of Stochastic Non-smooth Envelopment of Data (StoNED) for measuring efficiency has to date mainly found application in the analysis of production systems which have exactly one output. Therefore, the objective of this paper is to examine the applicability of StoNED when a ray production function models a production technology with multi-dimensional input and output. In addition to a general analysis of properties required by a ray production function for StoNED to be applicable, we conduct a Monte Carlo simulation in order to evaluate the quality of the frontier and efficiencies estimated by StoNED. The results are compared with those derived via Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA). We show that StoNED provides competitive estimates in regard to other methods and especially in regard to the real functional form and efficiency.  相似文献

This paper is amongst the first to examine coopetition strategy for sustainable development at the network level. Companies who want to successfully implement complex innovative technologies that support sustainable development need to collaborate with other actors of the innovation ecosystem, including their competitors, so that they can develop standards, interoperable products, pool knowledge, and resources and bundle forces to compete against other technologies. Collaboration with competitors brings benefits, but also many risks. We investigated how firms cope with these risks when establishing an innovation ecosystem to implement a new technology in society. We conducted research in the Dutch smart grids sector and explored how these firms minimize inherent risks of coopetition. We found that system‐building actors in the Dutch smart grid field not only minimize inherent risks, but from the start of their collaboration they implement so‐called enablers to prevent these risks upfront.  相似文献

Research on environmental reporting within individual sectors and industries is limited. Generic studies have typically focused on the reporting practices of the world's largest corporates. Some industries and sectors are under‐represented within these studies, limiting the potential for industry‐ or sector‐specific analysis. Forest and paper is one industry frequently under‐represented. This study examines environmental reporting amongst the top 100 forest and paper companies. The scale of environmental report publication is investigated, and the breadth and depth of reporting on the key industry issues of forest management and fibre procurement examined. The results show reporting is more prevalent amongst larger corporates but marked regional variations are evident. Most noticeably, Scandinavian companies are reporting more extensively, both in terms of the number of levels at which they report and the depth of information included on forest management and fibre procurement. Reasons for the marked regional variations in reporting are considered and markets for forest products and preferences within those markets for specific certification schemes identified as potential influencing factors.

Japanese auto makers are reported to enjoy high supplier performance through long-term relationships, specific investments, and sole sourcing. Quality management consultants in the U.S. have been strongly advocating adoption of these practices. But economic and management theorists would predict that the combination of a high level of relationship-specific investments and sole sourcing will lead to problems with supplier performance. In fact the Japanese auto makers use a hybrid form of organization we term parallel sourcing. We present a transaction costs model that shows how parallel sourcing provides incentives for supplier performance associated with multiple sourcing while preserving claimed benefits of sole sourcing.  相似文献

Practice rights legislation in Canada continues to be contested 50 years after its first enactment. In Ontario, one of the earliest provinces to enact restrictive legislation, the challenges have focused on how the legislation has been implemented rather than on whether or not public accounting should be regulated. To better understand the contested issues in this field, we examine the process undertaken by the Public Accountants Council of Ontario to implement the Public Accountancy Act of 1950. Our analysis is based on the first 15 years of the minutes of the meetings of the Public Accountants Council for Ontario, augmented by other archival sources such as court cases, newspaper clippings, correspondence and reports. Our intent is to document the process and “logic of appropriateness” used by the Council to construct its identity and stake out its “regulatory space” in the face of the ambiguity of the law and pressure from interest groups. We also identify the contradictions that were institutionalized in this field resulting in repeated challenges to the Council. We conclude by relating the historical insights from this analysis to the continuing challenges to practice rights legislation in Ontario.  相似文献

Two standard‐setting approaches have emerged globally to guide the choice of accounting for securitizations: the control and components approach (SFAS No. 125 and SFAS No. 140) and the risks and rewards transfer approach (IAS No. 39). A lack of consensus about derecognition accounting is a major impediment to achieving convergence in global standards that must be resolved. Thus, both SFAS No. 140 and IAS No. 39 will be reexamined, and evidence pertinent to the debate is timely and important. In this study, we present evidence consistent with the view of credit‐rating analysts, who view many securitizations as, in substance, secured borrowings. Specifically, for a sample of originators applying sale accounting guidance in SFAS No. 125 / 140 during the period 1997‐2003, we show that off‐balance‐sheet debt related to securitizations has, on average, the same risk‐relevance for explaining market measures of risk (that is, CAPM beta) as on‐balance‐sheet debt. We also find that, in a returns and earnings association framework, the pricing multiple on securitization gains declines as the amount of off‐balance‐sheet debt increases, implying that investors take off‐balance‐sheet debt into account when assessing the valuation‐relevance of such gains. For those who advocate the control and components approach to securitization accounting, our results suggest that, at least for frequent securitizers, the put option arising from implicit recourse is a “missing piece” that is not currently accounted for when calculating securitization gains. Our results challenge the extant measurement standards in SFAS No. 140.  相似文献

This paper describes the results of a mail survey to the educator membership of the American Marketing Association. Data were collected regarding beliefs about both the frequency of occurrence and severity of 59 ethical issues facing marketing faculty. The research questions examined include: What unethical practices are believed to most commonly occur? What practices are most severe? How do these beliefs vary by faculty rank and size and type of school? Implications for both the improvement of marketing education and for future research are provided.  相似文献

Dimensions of quality upgrading   总被引:2,自引:0,他引:2  
The impact of the Central and Eastern European (CEE) economies’ trade integration with European markets on CEE trade structures has been studied extensively. These studies frequently observe a quality upgrading of CEE exports. In this paper we consider three dimensions of quality upgrading: upgrading across industries, upgrading across different quality segments within industries and, finally, product upgrading within quality segments inside industries. For the analysis we partition industries into quality segments based on EU‐15 import unit values. The results for ten CEE countries (comprising the CEE‐5, the Baltics and South East Europe) and thirteen industries suggest fundamental differences, both across country groups and across the three different notions of quality upgrading. The CEE‐5 show no evidence of entering a ‘low‐quality trap’ in all three dimensions. By contrast, while there is a general catching‐up process across industries and inside quality segments, the second notion of low‐quality specialization may be applicable within the high‐tech industries to the performance for the Baltics and South East Europe as a group.  相似文献
