Shortcomings of the U.S. Antitrust Agency Guidelines method of market definition include failure to focus on competition, the need for cost data, and discontinuities. Two alternative approaches are presented which avoid these problems and the Guidelines' inclusion of substitutes on an all-or-nothing basis. One alternative focuses on the size of a change in capacity of a substitute that would be needed to have the same effects as a unit change in capacity of an initial item. The second proposed alternative offers a simple operational method of giving practical content to the “reasonable interchangeability” concept which is a prominent feature of U.S. Supreme Court decisions. The alternative approaches are evaluated in comparison to that of the Guidelines and some modified versions of the latter. 相似文献

This editorial discusses the issues and challenges of Ph.D. student supervision. Several academic colleagues with much experience in Ph.D. supervision were asked to contribute their thoughts on this important task. We present the tasks of supervision, including how these may be adapted depending on student characteristics such as extent of managerial experience. Then we explore the challenges faced by Ph.D. students, and discuss how these can be addressed. Following that, we examine the role of the supervisor in helping build student capabilities in publishing and teaching. Furthermore, we address the benefits of taking on supervisory responsibility. In the conclusion, the co-authors of this editorial provide retrospectives on their own experiences as Ph.D. supervisors. 相似文献

欧美是世界上最大的纺织品及服装进口国和地区,同时也是我国的纺织品出口的主要市场。长期以来,我国纺织服装出口受其配额的限制,通过长期艰苦的谈判,我国已正式成为世界贸易组织成员。作为目前世界上最大的纺织品服装出口国,一旦取消配额,会不会像人们预期的那样我国纺织品服装在欧美市场的份额大幅提升,甚至翻番?笔者认为,中国的纺织品出口将面临新的发展机遇与挑战,挑战大于机遇。鉴于机遇已有大量文章论述,本文将就我国纺织品出口将遇到的挑战作一专门的论述,以期抛砖引玉。 1.《纺织品服装协议》(以下简称ATC)执行不… 相似文献

近几年来,我国输美产品日渐增多。在这些输美产品中,凡外包装的色彩符合美国人需求的,进入美国市场后便容易销售;而一些外包装色彩不符合或不完全符合美国人需求的,则往往销路不畅。事实已充分说明,输美产品是否受欢迎,在很大程度上,取决于外包装的色彩。因此,研究美国人对包装色彩的需求,不断改进输美产品的包装色彩,是至关重要的。美国人对包装色彩有哪些特殊的心理追求与爱好呢主要有以下几点:一是庄重商品的包装色彩,宜采用红、蓝、白三种颜色。红、蓝、白三色是组成美国国旗的颜色。因此,美国人对其特别有感情。二是季节… 相似文献
