On the Merits of Vertical Divestiture

This paper demonstrates that vertical divestiture may increase consumer welfare even when the divestiture eliminates substantial scope economies and precludes only limited sabotage. More generally, the merits of vertical divestiture are shown to vary with: (1) the type and the intensity of competition in the retail market; (2) the locus of scope economies under vertical integration; and (3) the relative social values of consumers’ surplus and profit.     

状态方程计算高分子共混物的比体积

基于一个简单的非均核链流体分子热力学模型,采用不同形式的微扰项,可构筑不同形式的高分子共混物系统的状态方程。方程已被应用于关联聚苯乙烯/聚2,6-二甲基苯醚(PS/PPO)、聚苯乙烯/聚乙烯甲醚(PS/PVME)、聚苯乙烯/聚丁二烯(PS/PBD)、聚醚砜/聚氧乙烯(PESP/PEO)等高分子共混物的比体积。结果显示,用一个与温度无关的二元相互作用可调参数可满意关联所选体系的比体积,并可预测所选体系的比体积。     

峰谷分时电价的现状分析与发展趋势探讨

分时电价以经济学均衡价格为理论依据。它在引导客户合理用电、削峰填谷、优化电力资源配置等方面起了积极的作用。但它也存在分时价差幅度小、时段划分长、缺乏灵活性及实施范围窄等问题。完善分时电价运行机制,由分时电价向实时电价转变。     

关于输配电价几个重要问题的探讨

我国电力企业将要由传统的垂直垄断的模式转变为网厂分开、竞价上网的模式。电网公司作为一个独立的经营实体分离开来,有着独立的收益需求。在市场运营过程中,通过输配电价取得收益就成了电网公司取得收益的主要手段。在输配电价的制订过程之中,管制方式、输配电成本、输电定价方法、价格水平及电网投资、输配电价价区、电网提供的辅助服务等六个问题十分重要。文中就这六个问题的解决作了一些有价值的探讨。     

Social networks in the global banking sector

We show that banks with shared social connections partner more often in the global syndicated loan market and that central banks in the network play dominant roles in various interbank transactions, indicating that social connections facilitate business connections. However, more centralized banks in the network also contribute significantly to the global systemic risk. Moreover, we find the soft information generated by social networks is particularly valuable when potential partners operate under different accounting and regulatory standards. Finally, we show that the recent banking crisis significantly limited the positive soft information effects of social networks in the global banking system.     

Responsiveness of Auditors to the Audit Risk Standards: Unique Evidence from Big 4 Audit Firms

We examine the effect of changes in audit risk standards on the conduct of financial statement audits in a European setting. We investigate this by analysing the audit hours and audit fees for clients of Big 4 audit firms in Finland in 1996 and 2010. Our results show that audit firms became more sensitive to clients’ business risk due to the introduction of the new audit risk standards, with more audit hours allocated to owner-managed companies in 2010 than in 1996, and fewer audit hours allocated to low-risk clients in 2010 than in 1996. Also, the labour mix in the audit team changed for owner-managed companies, with a greater work load carried by junior auditors in 2010 than in 1996. Regarding the price of audit, we find an increase in audit fees for clients with high business risk, while audit fees remained at roughly the same level for low-risk clients. These findings should be of interest to the auditing profession and those involved in the development of auditing regulations.     

会计管制研究梳理及评论

文章主要介绍了国内外学者围绕会计管制的内涵界定、影响因素、经济后果、国际趋同以及公司治理与会计欺诈交叉研究等研究成果。在文献梳理中发现：我国的会计管制研究内容分散且观点存在分歧，仍停留在中心问题的边缘地带，对问题实质之处的挖掘还不够深入。西方理论界对会计管制的研究起步早、范围广，为国内学者提供了理论框架、技术方法等方面的研究指导，安然事件后《萨班斯法案》的出台，更引发了对会计管制的研究热潮。通过对会计管制研究进行脉络梳理和评论，以促进我国会计管制的广角研究。     

Competition,firm size and returns to skills: Evidence from currency shocks and market liberalisations

We investigate the impact of product market competition on returns to skills in Italy using a longitudinal dataset on individual working histories. This impact is identified using three exogenous shocks affecting competition: the unforeseen devaluation of the Lira in 1992, its return to a fixed exchange regime in 1996 and the market liberalisation in the utility and transport sectors in the late 1990s–early 2000s. We analyse how firm heterogeneity and shocks of different types and signs affect the impact of competition on skill premia. We find that opposite shocks have opposite effects: an increase (resp. decrease) in international competition increases (resp. decreases) skill premia. Moreover, international shocks have greater effects on medium sized firms, while domestic liberalisation shocks have greater effects on large incumbents.     

The design of light-handed regulation of airports: Lessons from experience in Australia and New Zealand

The difficulties experienced with traditional forms of economic regulation of airports involving direct control of prices have led to an interest in light-handed regulatory frameworks. Experience with light-handed regulation of airports is primarily confined to Australia and New Zealand. The paper examines the design features of light-handed regulation in Australia and New Zealand in relation to the stated objectives associated with the introduction of light-handed regulation. The paper identifies important aspects associated with the design of light-handed regulation including the incorporation of a credible threat of stronger regulation and the characteristics of this, and an apparent trade-off in objectives achieved with different approaches to light-handed regulation.
