A new continuous distribution and two new families of distributions based on the exponential

Recent work on social status led to derivation of a new continuous distribution based on the exponential. The new variate, termed the ring(2)-exponential, in turn leads to derivation of two closely related new families of continuous distributions, the mirror-exponential and the ring-exponential. Both the standard exponential and the ring(2)-exponential are special cases of both the new families. In this paper, we first focus on the ring(2)-exponential, describing its derivation and examining its properties, and next introduce the two new families, describing their derivation and initiating exploration of their properties. The mirror-exponential arises naturally in the study of status; the ring-exponential arises from the mathematical structure of the ring(2)-exponential. Both have the potential for broad application in diverse contexts across science and engineering. Within sociobehavioral contexts, the new mirror-exponential may have application to the problem of approximating the form and inequality of the wage distribution.

“Going to market”: Changing patterns in the organisation and character of process research

This paper explores a meta level question in process research: the implications of the move to a more market based mode of research now evident for the production of process knowledge. It first of all examines the implications for the changing organisation of process research. For example, there has been the emergence of a group of contract process researchers. These researchers may also form alliances with researchers from other disciplines within multidisciplinary teams. Second, it examines implications for the changing character of process knowledge in relation to criteria of internal and external validity. Different effects are evident at different stages at the research cycle, but it is argued that there is no inherent threat to concepts of validity. These trends are exemplified by a project on which the authors are currently engaged. The article concludes with a discussion about the possible future for process research.     

学习能力影响下供应链企业间知识交易的最优合约配置!

在知识买方——供应链中的供应商的学习能力为其私人信息的情况下,知识卖方——制造商通过设计将知识交易量与原材料产品折扣价格相结合的合约菜单来甄别供应商的学习能力类型。在此基础上,建立信息不对称情形下的知识交易模型,通过模型求解得出最优的合约配置,并结合信息对称情形下的基准情形对合约菜单的相关性质进行了分析。最后利用数值算例对上述相关性质进行了说明。

Technological character,function type,and the longevity of standardized knowledge

This study seeks to determine the validity of the current de jure standards management system. The de jure standard is an important tool for innovation policy. However, its review interval has been fixed in the management system and maintained without the use of empirical analysis to guide its development. Therefore, this study (1) examines the factors that affect the longevity of the standards, and (2) outlines methods for improving how the de jure standards are managed. Results indicate that design and mark standards influence the longevity of standardized knowledge. This is notable, given that design for innovation is an emerging area of research that is commonly studied through the analysis of design patent data. Taken together, this study’s major findings are twofold. First, different technological categories have significantly different effects on longevity. Because the longevity of some technological sectors is naturally longer than others, there exists a need for a more flexible interval system. Second, the longevity of the mark and design standard is longer than the longevity of other types of standards. Both developing and developed countries utilize the de jure standard, so the policy implications of these findings are widely applicable.     

PERFORMANCE‐BASED FEE CONTRACT AND RISK‐TAKING STRATEGY IN ASSET MANAGEMENT TOURNAMENT

This paper investigates how performance‐based fee (PBF) contracts affect strategic risk‐taking behaviours of fund managers in an asset management tournament. In the perfect equilibrium, managers with better mid‐year performance will hold the risky asset with a higher probability in the remaining of the year, compared to managers with poorer mid‐year performance. If the volume of the cash flow into the winner fund is contingent on its level of success, the winning fund will take a more aggressive approach. When the PBF contract pays more heed to relative performance against the benchmark, managers are more likely to adopt aggressive strategies.

独立董事比例、产权性质与长期债务融资契约

独立董事比例越高则长期债务融资比重越大,这一现象只在民营上市公司样本中有稳定表现,原因在于独立董事比例越高,监督能力越强,民营公司独立董事承担的监管风险相对更高,监督动力更强。监管当局应该适当提高上市公司独立董事比例,严格独立董事责任机制,以进一步改进独立董事制度效率。
