浅析资本弱化与外资避税

随着现代资本结构理论的发展,国内外企业都在学习如何在实务中对其加以灵活应用,使企业价值最大化.资本弱化就是这样一种应用,其目的在于企业通过资本结构安排,改变其纳税义务,起到避税的作用.目前,来自发达国家的外资企业在这一避税手法的使用上已达到了十分成熟的阶段,再加上我国现行税制框架尚未对资本弱化进行识别、规范和控制,造成了我国大量的税收利益流失.另外,在我国已逐渐认识到问题的紧迫性的情况下,如何进行监管和控制也是一个很大的技术难题.     

企业转让制度之比较研究

企业转让是指为了一定的营业目的通过签定合同将企业作为一个有机组织体的全部财产或部分重要财产进行有偿转让的活动。它是企业的所有权在不同的市场主体之间的移转,既不同于货物买卖也不同于企业财产的转让。企业转让制度在《德国商法典》、《日本商法典》和《韩国商法典》中都有专门规定,但在《澳门商法典》中规定的更为全面,主要涉及商号、债权债务关系、竞业禁止和劳动关系内容。建立企业转让制度是市场经济的内在体现,对我国发展经济和解决就业有着重要的现实意义,同时也符合我国建立现代产权制度的要求。

Frictions, Heterogeneity and Optimality in Mortgage Modeling

The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework.     

Information Content of Earnings and Earnings Components of Commercial Banks: Impact of SFAS No. 115

SFAS No. 115 modified classification of debt and equity securities held by firms and also modified the reporting format for unrealised gains/losses on security transactions (URGL). This study investigates whether implementation of SFAS No. 115 improved information content of earnings and earnings components of commercial banks. Improvement in the information content is measured by comparing the association between equity returns and earnings and earnings components of the post-adoption period of SFAS No. 115 with the pre-adoption period.The test results indicate that the association of equity returns with earnings components and aggregate earnings is significantly stronger in the post-adoption period compared to the pre-adoption period. The improvement is especially evident for the components of URGL and non-interest revenues. These results suggest that information provided by earnings components is considered more value relevant for investment decision after implementation of SFAS No. 115. Findings on non-interest revenues indicate that revenues from banking activities other than lending also play an important role in the commercial banks' profitability.     

企业多元化的新模式：基于核心能力的虚拟经营

本文研究了企业多元化经营的科学含义，创建了一个二元作用定性模型来论证企业发展到一定阶段多元化经营的必然性，研究了现代企业虚拟经营的背景，含义以及企业深化，培育核心能力与开展虚拟经营之间的本质联系，考察了多元化成功与失败的众多企业案例，当代多元化经营成功的企业大多是基于核心能力的战略相关多元化，而虚拟经营也是核心能力培育，深化的产物，借助于基于核心能力的虚拟经营以实现相关多元化发展，是企业多元化的一条新途径，相对于传统多元化而言，它更具竞争优势。     

The measurement of corporate portfolio strategy: analysis of the content validity of related diversification indexes

Measures developed for the analysis of corporate diversification have become fundamental to a broad range of strategy research. This paper examines the content validity of the two most widely used continuous measures of related diversification—the related component of the entropy index and the concentric index—and raises fundamental questions about their validity as indicators of portfolio relatedness. These questions are not driven by the use of SIC data for estimation of the indexes; they involve validity problems intrinsic to the construction of the measures. The related component of entropy and the concentric index are sensitive to features of corporate portfolio composition that may not be directly linked to portfolio relatedness. These sensitivities can create important ambiguities in strategy research. Copyright © 2002 John Wiley & Sons, Ltd.     

我国涉外企业外汇交易风险研究

随着世界经济逐步向全球一体化的方向发展以及我国对WTO相关条款的逐步履行,我国与其他国家的经济往来也变得更加频繁。更为重要的是,我国外汇管理体制改革的进一步深化和外汇市场的发展和完善,使得人民币汇率开始走向市场,汇率变动的频率和范围将大大增强。因此,在这一背景下,本文以科学性和前瞻性为指导原则,通过阐述我国涉外企业面临的外汇交易风险现状和问题,揭示这类企业加强外汇交易风险管理的必要性,在此基础上,来探讨外汇交易风险对我国涉外企业净利润的影响,最终结合我国外汇管理体制改革的实践,提出有效防范和规避外汇交易风险的建议和对策。     

Behavioral assumptions and theory development: the case of transaction cost economics

From a critical realist perspective, I discuss the role played by behavioral assumptions in organization theories, and use transaction cost economics as an illustrative example. Core behavioral assumptions often constitute the foundation of the mechanismic explanations of a theory, and thus should play a pivotal role in theory development. I distinguish between assumption‐based and assumption‐omitted theory testing, and show that empirical research in transaction cost economics has been dominated by assumption‐omitted testing. To establish a solid foundation for a new theory, management researchers should pay more attention to assumption‐based testing. Copyright © 2006 John Wiley & Sons, Ltd.
