US—Soviet grain embargoes: Regulating the MNCs

The US government has often attempted to regulate commercial interaction between US grain MNCs (multinational corporations) and the Soviet Union. The US government tried to prohibit the sale of grain to the Soviet Union prior to 1971, to swap US grain for Soviet oil in 1975, and to embargo all grain sales to the Soviets in 1980. Distinctive characteristics of grain MNCs and grain as a commodity, however, have made such efforts at national regulation by the US government a difficult administrative task. These characteristics include the secrecy surrounding grain trading, the fungibility of grain, the use of ‘optional origins’ contracts, and the possession of a considerable number of foreign subsidiaries by the grain MNCs.     

汽轮油泵出口圆球故障对调节系统的影响

60 0 0kW汽轮机多数都将汽轮机启动用的离心式油泵与一微型小汽轮机的转子同轴装配成一体 ,称汽轮油泵 ,半埋于机组的主油箱中。这种结构具有紧凑、漏点少、操作方便、不易发生故障等优点。特别是由于半埋于主油箱中 ,运行时的热量传递给透平油的速度比较快 ,油温易建立 ,不需增设加热装置 ,故机组也易启动。但这种结构往往也易被人们所忽视 ,C6-3 .43 /0 .981型汽轮机所配置的BL -5 .5 -2 4型半埋式汽轮油泵出口圆球发生故障的情况就是较典型的一例。一、故障现象某日 ,因电气系统原因 ,1# 汽轮发电机组从电网解列、停机。电气故障处理完…

Regulating the European Labour Market: Prospects and Limitations of a Reflexive Governance Approach

This article reviews developments in European Union employment policy from the perspective of reflexive governance. Reflexive governance instruments have a procedural orientation and provide a structural framework or steering mechanism to facilitate a process of self‐regulation. Recent developments in relation to the Employment Framework Directive, the European Employment Strategy and the Working Time Directive highlight some of the prospects and limitations of this reflexive approach to regulating employment relations and the potential impact on the UK labour market. These developments indicate that the hopes invested in the reflexive approach remain to be fulfilled.

全球纺织品取消配额的几个月来,欧美联手同步对我国纺织品进行合围,我国纺织企业必须认真研究并调整后配额时代的长期战略,有效地保护与提高企业的国际竞争能力。     

建立有效且有限的政府规制机构

在我国转轨的过程中,市场经济还不成熟。此时,自然垄断产业引入竞争的市场化改革成功与否的一个关键问题就是政府规制机构能否真正发挥作用。因此,在自然垄断产业改革过程中,要加快自然垄断产业规制机构改革,建立一个有效且有限的政府规制机构。这个规制机构主要职责是创造良好的市场竞争环境,以充分调动市场主体的积极性,发挥其潜力。

Regulating prices in two-sided markets: The waterbed experience in mobile telephony

The distinguishing feature of two-sided markets is that the pricing structure, that is, the relative prices charged to each side, matters. Regulators need to understand and account for the interdependence of prices in both sides. Some interventions that lower the prices on one side can result in higher prices on the other side of such markets. This article reviews the recent literature analyzing this waterbed phenomenon in mobile telephony and draws some more general lessons for policy interventions in two-sided markets.     

进场费的政府规制效果分析——基于权力范式的渠道研究

近年来,进场费问题始终是零售商与供应商矛盾冲突的焦点,也是理论界和政策制定者关注的热点。本文基于经济学研究的权力范式,构造了以政府规制强度为外生变量的供应商与零售商博弈模型,从理论上分析了进场费的作用及限制进场费对零售商、供应商的决策行为和消费者福利的影响。结论是:进场费作为渠道利益分配调节机制,客观上具有传递零售终端竞争压力的作用。限制进场费会减少零售商的利润,但不一定增加供应商的利润,且有可能削弱供应商改进产品的动机和刺激零售商扩张销售网络。

Regulating B2B online reverse auctions through voluntary codes of conduct

In response to real and perceived abuse by market makers, buyers, and sellers, some industry trade groups representing suppliers have developed voluntary codes of conduct, white papers, and other forms of guidance for online reverse auction participants. The intent of these guidelines is to improve both the reverse auction process and relationships between buyers and sellers. This paper examines the rationale for creating guidelines and codes of conduct, and examines their efficacy in regulating reverse auctions to achieve improved outcomes for market makers, buyers, and sellers. Data from primary and related secondary sources indicate that industry-specific codes of conduct and guidelines have not had a favorable impact.     

非工资性收入分配：国有部门收入调控的新视角

本文基于"中国居民健康和营养调查"(CHNS)数据,研究所有制性质与非工资性收入分配问题。通过对中国非工资性收入结构和差异格局的长时段考察、研究发现,在津贴、补贴和医疗保险等非工资性收入方面,国有部门都明显高于其他部门,非工资性收入差异造成了我国不同所有制部门间收入差距的扩大,非工资性收入的不平等程度高于工资收入,而且呈不断上升的趋势。进一步利用Panel Data模型及Logit模型分析非工资性收入差异扩大的原因,研究表明,受教育程度、年龄和职业等因素对非工资性收入的影响程度较低,引起非工资性收入差异扩大的主要原因是所有制性质因素。因而,防止非工资性收入差异扩大,规范国有部门非工资性收入应成为当前收入分配制度改革的重点。
