The Panzar–Rosse revenue test and market power in banking

The Panzar–Rosse H statistic is a commonly used measure of market power in banking. It is widely believed that $H>0$ is inconsistent with significant market power. This study rigorously disproves that perception. Instead, the possibility of $H>0$ under conditions of substantial market power turns out robust to the timing of banks’ actions, relative costs, choice of strategic variable, degree of product differentiation, strategy (static or dynamic), and degree of heterogeneity in banks’ conduct (collusive versus fringe), and hence may be common in practice.     

市场需求和竞争对供应链绩效的影响

假设市场需求函数是线性的,分析了两种情形下供应链间的价格竞争。在第一种情形中,供应链是集中式决策的;在第二种情形中,供应链是分散式决策的,即制造商和零售商独立进行决策。研究了不同的价格竞争水平和潜在市场需求对供应链成员绩效的影响,结果表明,在一定的价格竞争水平下,潜在的市场需求变异系数能决定分散式供应链是否优于集中式供应链。     

Reconceptualizing competitive dynamics: A multidimensional framework

Competitive dynamics research, despite progress, lacks a conceptual framework that can extend the field's reach to address today's environment. Increasing stakeholder power and globalization are but two of the organizational and economic forces compelling a broader conceptualization of competition. Our framework expands competitive dynamics along five dimensions—aims of competition, mode of competing, roster of actors, action toolkit, and time horizon of interaction—that prove useful for contrasting the rivalrous and competitive‐cooperative modes and a new approach we call relational competition. We draw conjectures about the moderators, such as industry and culture, that determine the appropriateness of these forms of interaction, and conclude by relating our method to three discrete perspectives: the configurational, transaction cost, and stakeholder views.

京津冀地区经济差距及财税政策调控研究

随着社会经济的全球化发展,区域经济一体化成为一种必然趋势,逐渐受到越来越多人的重视,但基于我国国情,各地区经济的不均衡发展也是无法避免的,经济差距过大会给区域经济的发展带来不良影响,进而制约我国社会经济的全面发展。本文通过对京津冀地区经济发展现状进行分析,详细阐述了造成三地经济差距的主要原因。在此基础上,本文通过财税政策对京津冀地区经济差距的影响的深入研究,并针对该区域的财税政策进行分析,提出了缩小京津冀地区经济差距的有效措施。     

中德反不正当竞争法之比较

德国是现代反不正当竞争法的发源地。 1 896年德国制定了世界上第一部专门的《反不正当竞争法》 ,后经若干次修订 ,至今仍对促进德国经济的发展起着举足轻重的作用 ;1 993年中国颁布第一部专门的竞争法律《反不正当竞争法》 ,至今已运行近 1 0年。比较两国在不正当竞争行为的概念和类型、适用除外制度、法律责任等方面的特点 ,给我们有益的启示 ,我国在完善《反不正当竞争法》的同时 ,应协调好与《反垄断法》的关系     

孤东油田水平井打捞优化技术

长期以来,孤东由于水平井特殊的井身结构,作业打捞井下落物这个"疑难杂症"一直被视为作业施工中难啃的硬骨头,水平井水平段内的落鱼打捞(特别是滤砂管打捞)作业是一个难题,由于造斜段的原因,井口上提力、扭矩等无法全部传递到井下水平段内,因此常规打捞措施无法实施。为了突破水平井作业施工中的"瓶颈",从现场出发,对水平井管柱受力及打捞难点进行分析,对打捞工具选择、工具尺寸进行优化,管柱进行了优选,满足现场打捞需要。     

China's Emergence and Its Implications for Europe's Economies

Abstract

This paper assesses how the competition between China and the EU in export markets has affected the trade performance of European countries. It first draws on a comparison between Germany and France before turning to discuss the economic and social impact of China's internationalization on Europe's economies. The results suggest that even in the recent years when China has gained prominence, it should not be blamed for more than half of the measured effects for emerging countries.     

产品市场竞争与代理成本

通过构造以Hotelling价格竞争模型为基础的多阶段博弈模型,首先分别分析了在信息对称与信息不对称情况下管理者的努力程度与所有者激励管理者存在的代理成本,然后讨论了在信息不对称情况下外部产品市场的竞争程度对于代理成本的影响。通过分析我们认为外部产品市场竞争程度越高,代理成本越低,外部产品市场能够成为一项促进公司治理绩效的工具。     

零售商自有品牌及其竞争效应

目前,零售商开发自有品牌已经成为全球零售业发展的一个显著的特征。自有品牌有助于零售商驱除在位竞争对手或阻止潜在进入,同时也提高零售商在纵向竞争结构中的议价势力,并产生促进竞争效应和反竞争效应。
