CEV模型的单位根检验研究

CEV模型（Constant Elasticity of Variance Model）作为常用的利率模型，在实证分析中得到了广泛运用，但是其单位根检验一直被忽略或者被默认可以使用迪基一富勒检验。本文首次运用Box—Cox变换的技巧，针对CEV模型的单位根检验问题，找到了合适的统计量并且证明其渐进分布存在，然后通过蒙特卡罗方法求出了该统计量的分布表。得到了在大样本的情形下可以沿用迪基一富勒检验，但在小样本的情形下与迪基一富勒检验有所偏差的结论。

Individual rights and organizational theory

Rights are very important concepts in everyday life. And they are especially important to participants in organizations. Yet, our theories of organization and management have largely ignored rights — stressing, instead, other concepts, such as goals, roles, etc. This article describes the historical significance of rights and their relevance in understanding social behavior. The advantages of a right-based organizational theory (versus traditional goal-based theories) are discussed.This article draws on the author's forthcoming book,A Social-Contract Theory of Organizations (University of Notre Dame Press, 1988).     

An alternative employee rights paradigm: Labor process theory

A dialectical relationship exists between the capitalist desire for accumulation of wealth and profits, and the rights of employees. Labor process theory exposes facets of the fundamental incongruity between the interests of employers and workers in a capitalist political economy. An analysis of employee rights through the labor process framework facilitates the potential for human emancipation by illuminating the ideological, political, and economic sources of domination and repression that are embedded in the capitalist system. In this article, three core elements of labor process theory—the social relations of production, the managerial control imperative, and the restructuring of work—are used to highlight ways in which organizations maintain their hegemonic position. This exposé offers the basis for an alternative paradigmatic view of the employment relationship and informs our thinking of how employee rights are impacted, and often tempered, in work organizations. Portions of this article were presented by both authors at the 12th Annual International Labour Process Conference March, 1994 in Birmingham, England.     

Are UK technology-based small firms still finance constrained?

This paper examines funding issues for UK Technology-based Small Firms (TBSFs). TBSFs are the cry of today and UK government like other countries is trying to increase the mass of TBSFs by various means. However, it is reported that TBSFs face many impediments to their successful development. Finance is believed as the main barrier at the early stages of TBSFs development. This paper is attempting to follow up and report if the funding situation for UK TBSFs has improved. The findings reported in this paper suggest that nearly 80% sample firms were finance constrained at the early stages of business development.     

最终控制人特征与上市公司现金股利政策

本文以2002年-2004年上市公司的股利分配数据,实证检验了最终控制人的特征对上市公司现金股利政策的影响.结果表明.上市公司现金股利政策与最终控制人的侵害动机成反比,现金股利的支付率随着最终控制人控制权比例的增加呈先减少后增加的U形变动;两权分离程度越小,派发现金股利的水平就越大,但这种影响主要来自于较高的现金流量权,现金流量权比例越大,派发现金股利的概率和水平也越大;最终控制人性质为政府尤其是地方政府时,上市公司派发现金股利的概率和水平更高.

解读会计信息产权

会计信息外部性的存在带来会计信息供求的冲突,解决此冲突的规则就是会计信息产权。会计信息产权需要界定才能发挥其应有的效能,会计信息产权的界定取决于对企业所有权分享、管制和道德等因素,企业所有权分享下的会计信息产权界定是初始的界定,无法完成初始界定时可采用管制方式进行强权界定,道德是会计信息产权界定不可缺少的因素。国企改革所滋生的各种问题的根源在于会计信息产权畸形性,欲抑制其畸形,正确处理国企所有权的分享问题的同时,建立“共同治理”的机制和“相机治理”机制是必不可少的。     

汇率波动率与中国对主要贸易伙伴的出口

本文研究汇率波动率对中国向三个主要贸易伙伴美国、欧盟和日本出口的影响。通过协整检验,误差修正模型和Granger非因果检验等方法估计变量间长短期的关系。研究表明,中国向美国和欧盟的实际出口与实际汇率波动率存在长期显著的负相关关系,而中国向日本的出口与汇率波动率无关。短期内汇率波动率只影响中国向美国的出口,对向欧盟和日本的出口没有影响。
