Multiple aspect testing for case-control designs

When testing for the equality of two distributions in a case-control design with treatment effects presumed to act possibly on more than one aspect, different tests may be properly considered for testing for different features of a null hypothesis, leading to the multiple aspect testing issue. Two different aspects are therefore of interest: the location-aspect, based on the comparison of location indexes, and the distributional-aspect, based on the comparison of the empirical distribution functions. A simulation study shows that the combined testing procedure exhibits a good robust overall performance, and an application in biomedical research is also presented.     

Linking performance drivers in production planning and inventory control to process choice

This study investigates how process choice relates to production planning and inventory control decisions. We empirically examine the validity of deductively derived patterns about these types of decisions. More importantly, we look for normative insights by exploring how production planning and inventory control decisions affect operations performance. Our findings show that production line and continuous flow plants use more of a level production strategy, and carry less raw material and work-in-process inventory. The performance drivers for these plants, through which the operations function excels, are effective utilization of equipment, reduced finished goods inventory, and reduced setup down time. To gain forward demand visibility and batching economies, job and batch shops rely much more on backlogs in their planning process. These plants use more of a production chase strategy and position inventory lower in the bills of materials. Four performance drivers for top-performing job and batch shops are to find ways that better anticipate customers' orders, have a more responsive chase strategy, carry less raw material or purchased inventory, and shorten production planning horizon, partly through less reliance on backlogs. It is intriguing that top-performing plants not only do the expected things, given their choice of process, but also excel in selected dimensions—some of which fit the profile normally associated with a different process choice. To monitor and continuously improve operations, evaluation ‘scorecards’ should pay particular attention to performance drivers, which change depending on the plant's process choice.     

中外管理者收购融资的比较与启示

国资委、财政部正式公布了《企业国有产权向管理层转让暂行规定》,对MBO的实施范围作了界定,对实施主体提出了规范化要求。文章比较研究了国内外MBO不同的融资模式,认为我国企业管理者收购受有关法律和金融制度的限制存在融资工具和融资机构单一,融资渠道和退出渠道不畅等问题,其潜在的法律和金融风险不可忽视。最后,笔者对改进我国管理者收购融资提出了新的政策建议。

中小企业研发困境的博弈分析

知识经济时代，企业自主研发是增强其竞争力的必经途径。而在国内，众多中小企业对研发投入持消极态度，尽管政府多方鼓励，但收效不大，且企业在自主研发的投入方面与发达国家有着较大的差距。可从严格保护研发成果、协作研发与加大政府的政策优惠力度等方面对中国中小企业的研发投入情况进行改进。     

国外并购绩效评价方法研究综述

20世纪全球经历了5次企业并购浪潮,并购已经成为现代企业尤其是大型企业和高成长企业快速扩张和整合的重要手段之一.企业并购的之后的效果如何,如何来评价并购的绩效,国外学者从不同角度做了大量的研究,但数十年的研究至今没有一个统一的结论.本文总结了30多年以来国外学者有关企业并购绩效研究的重要文献,在此基础上将国外并购绩效的评价方法分为财务评价、股票评价和其他评价三类,并指出了并购绩效评价方法中存在的问题.
