基于终极产权论的股权结构与公司绩效研究

文章依据终极产权理论,对我国制造业上市公司股权进行重新划分,分为国有终极控制权和非国有终极控制权.采用面板数据方法,在控制样本选择偏差和股权内生变量的前提下研究股权结构对公司绩效的影响.实证结果表明,终极控制权比例与国有控股公司绩效CFOA、M/B呈显著的倒U性关系,而与传统绩效指标ROE、ROA无显著关系,在非国有终极控股公司中则不存在上述关系.流通A股比例与公司绩效关系不确定.样本选择偏差、机构投资者和外资股对公司绩效也有不同的影响.

DEVELOPING SOCIAL IDENTITY AND SOCIAL CAPITAL FOR SUPPLY CHAIN MANAGEMENT

Competition involves not firm against firm but rather supply chain against supply chain, but few studies explain theoretically the subsistence of a supply chain as a social entity or the operating mechanisms through which firms socialize to obtain better business performance. On the bases of social identity theory and social capital theory, the authors suggest that the salience of supply chain identity accumulates social capital in a supply chain, which then facilitates supply chain management and improves business performance.     

The Operating Performance of Newly Privatised Firms in Central European Transition Economies

This study examines the operating performance of privatised firms in three Central European Transition Economies between 1990 and 1998. Overall, we find no evidence of a significant improvement in operating performance for the first six years after privatisation. Contrary to the increasing empirical evidence for non‐transition economies, our privatised firms experience no improvement in profitability, capital investments, efficiency, and output, a significant drop in employment, as well as a significant increase in leverage. The most important determinants of the performance changes following privatisation were country effects, timing of the privatisation sales, industry classification, and state ownership after privatisation. Our findings are consistent with the empirical evidence that the transition process proved to be more difficult than expected and that, although necessary, privatisations do not necessarily produce equal efficiency gains in transition economies ( Megginson, 2005 ; Havrylyshyn and McGettigan, 1999 ).     

关于我国证券交易印花税制度的若干思考

尽管我国证券交易印花税在获取财政收入、调节证券市场方面具有一定的作用,但其制度本身还存在许多缺陷,如:征收缺乏法律依据、职能错位、征收范围狭窄、双向同率征收、调节力度欠佳等。为了让印花税名至实归,本文认为应当改革我国现行的证券交易印花税,同时完善证券市场上的其他税种。     

Security Choice, Information Effects and Firm Characteristics: A Factor Analytic Approach

Abstract:   We examine the marginal choice between debt and equity securities using a factor analytic approach. This data reduction property eliminates the need to select the one best variable to proxy for a particular theoretical construct. Our results reinforce numerous existing findings using traditional methods and suggest both static tradeoff and asymmetric information based considerations are relevant in determining security choice. Two new results are presented related to the accounting liquidity of the firm. First, the preference for equity is increasing with liquidity as suggested by the window of opportunity hypothesis. Secondly, the market response to equity issuance announcements is inversely related to the liquidity of the firm. Profitability and growth measures support Jensen's (1986) agency cost of free cash flow as a potential explanation for the second finding.     

Underpricing and aftermarket performance of American depositary receipts (ADR) IPOs

American depositary receipts (ADRs) are negotiable instruments representing foreign company shares traded in US dollars in the US capital market. We present comparative analyses of the pricing and aftermarket performance of Initial Public Offerings (IPOs) by ADRs and a matching sample of US firms over the 1990–2001 period. Offered by large, well-known multinationals, ADR IPOs go through a detailed scrutiny, and incur significant costs, during the pre-IPO period to recast financial statements in conformity with SEC rules and the US GAAP. This mitigates the information asymmetry between the IPO firm and investors. We categorize the ADR issuing country as developed or emerging, and our sample includes several cases of privatization of state owned corporations. The analyses indicate that (1) ADR IPOs are significantly less underpriced than comparable US IPOs; (2) IPOs from developed countries are more underpriced; and (3) Privatization IPOs are less underpriced than non-privatizations. The lower underpricing of ADR IPOs persists even after differential IPO attributes, the traditional proxies for information asymmetry and, the unique characteristics associated with ADR IPOs, are accounted for. We conclude that extant literature offers only partial explanation for this puzzling phenomenon.

欧元区统一货币政策绩效及其对中国的启示

欧元产生以来,欧洲中央银行在统一货币政策的框架下较好的实现了物价稳定的首要任务,却未能有效促进欧元区的经济增长、充分就业和国际收支平衡,主要原因在于:成员国经济基本面的差异使统一货币政策产生了巴拉萨-萨缪尔森效应。由此给当前正致力于货币合作的东亚地区带来了一个重要启示:应不断加强各国间的政策协调,确保主要经济指标高度趋同,为将来单一货币的实行奠定重要基础。
