Market Shares and Concentration in the EU Auditing Industry: the Effects of Andersen’s Demise

This paper describes and analyses changes at the concentration level of the audit services markets in 15-EU member-countries. The sample consists of 2,862 clients of auditing firms for the period 1998 to 2004. The findings of the research show that concentration in the aggregate sample increased over time. Concentration in the audit markets of the EU-15 member-countries exhibits substantial variation across countries while average concentration, before and after Arthur Andersen’s dissolution, has increased in 12 and declined in three countries. Results segmented by economic sectors indicate that the concentration increased in all sectors except Energy, which is the sector with the highest concentration. Overall, the empirical results suggest that there are complexities in our understanding of auditing services markets for competition purposes.

TRANSATLANTIC CAPITAL MARKET PRICE DISCOVERY DURING A FINANCIAL CRISIS

Previous results show relatively small amounts of time variation in the Hasbrouck (1995) information share across international markets. Using data from a security that was cross‐listed on the New York and London Stock Exchanges in the 1860s, we find that the information share changes dramatically during a financial crisis that began in the foreign market.     

Why are shareholders not paid to give up their voting privileges? Unique evidence from Italy

Dual-class share unifications have typically been argued to be beneficial for voting shareholders, who are usually compensated for the loss of their superior voting privileges. However, no covenants exist that make this compensation mandatory for voting shareholders. In this paper, we examine a subset of dual class share unifications from Italy where, in the main, voting shareholders are not offered any compensation in lieu of the loss of their superior voting rights. We present a simple model describing the conditions under which the controlling voting shareholder will choose not to offer compensation to minority voting shareholders as part of a share unification. Our empirical results support the model predictions.     

Does aging influence structural change? Evidence from panel data

Our study represents a first attempt to single out the effects of aging on the entire structure of the economy that is approximated by employment shares in different sectors. We find that even after controlling for the effects of other relevant factors - e.g., income per capita, share of trade in GDP, government consumption share in GDP, population size - aging does have a statistically significant differentiated impact on the employment shares. In particular, we find that an increase in aging exerts a statistically significant adverse effect on the employment shares in agriculture, manufacturing, construction, and mining and quarrying industries. At the same time, an increasing share of the elderly (decreasing share of the youth) in society positively affects employment shares in community, social, and personal services as well as in the financial sector.     

The Morishima gross elasticity of substitution

We show that the Hotelling–Lau elasticity of substitution, an extension of the Allen–Uzawa elasticity to allow for optimal output-quantity (or utility) responses to changes in factor prices, inherits all of the failings of the Allen–Uzawa elasticity identified by Blackorby and Russell [(1989) Am Econ Rev 79: 882–888]. An analogous extension of the Morishima elasticity of substitution to allow for output quantity changes preserves the salient properties of the original Hicksian notion of elasticity of substitution. We thank Paolo Bertoletti for drawing our attention to the issue addressed in this paper and for his comments on an earlier draft.     

股权分置改革视角下独立董事对议案事项监督机制研究

采用2005—2014年我国上市公司独立董事对议案事项意见的独特数据,从明确监管议案事项、非明确监管事项和股权分置改革等三方面深入考察其对独立董事出具否定意见的影响。研究发现,在我国上市公司中,对明确监管议案事项出具否定意见概率低,说明“逆淘汰”机制和“任人唯亲”董事会文化的存在使得监督效果大打折扣。同时发现,在股权分置改革后,独立董事对议案事项出具否定意见概率更低;出于规避法律风险的考虑,独立董事对明确监管事项出具否定意见的概率相对较高。因此,监管层应加强对各类议案事项检查力度而非仅仅明确监管事项;科学厘清独立董事在董事会决策中的责任边界,明确独立董事承担的法律风险。

我国上市公司控制权市场公司治理效率——基于股权分置改革的研究

股权分置改革后,对股权分置问题的研究,从应否改革、如何改革等问题,转到改革后我国控制权市场能否走上健康发展的轨道,控制权市场外部治理机制能否有效约束公司管理层和大股东的行为等问题上来。本文就我国上市公司控制权市场的公司治理效率进行了实证研究,得出了股权分置改革前后我国上市公司控制权市场低效率的研究结论。     

混合所有制改革、国有股比例与企业价值

本文选取2014～2019年我国A股国有上市公司为研究对象,探讨了混合所有制改革与国有股比例对企业价值的影响.结果表明,实行了混合所有制改革的国有企业,其企业价值会显著提高,国有股比例与企业价值之间存在倒"U"型关系,进行混合所有制改革的国有企业的国有股比例存在阈值效应,且阈值为28.65％.因此,政府需继续鼓励非国有...     

从国营到国有——国家股转让效果分析

本文系统地研究了从1997年到2000年在上海证券交易所和深圳证券交易所发生的国有资产局将控制权转让给国有独资企业和国有法人企业的案例数据。研究发现国家股控制权转让后公司业绩有了明显的改善,同时证券市场对国家股转让行为做出了积极的反应,产生了明显的超额收益。
