From rationality to hyperreality: paradigm poker

This paper, following McGoun's (1997) seminal article comparing the economy of financial securities to a hyperreal poker game, argues that finance and accounting researchers should take the “linguistic turn” that has rejuvenated theory and research in many, if not most, of the social science and humanities in recent decades. In general terms, this means following Ludwig Wittgenstein's language game paradigm rather than Karl Popper's scientific deductive hypothesis testing methodology. The paper illustrates this by drawing on some of Jean Baudrillard's' ideas, particularly his concept of hyperreality and his phases of the image theoretic.The paper presents a poststructuralist genealogical analysis of the radical ruptures and reformulation of the meaning attributed to the accounting sign of earnings over the feudal, counterfeit, production, and simulation eras. It concludes that, as with many other signs in contemporary society, the earnings sign no longer has any relationship with, nor does it any longer refer to, any real or intrinsic profit but instead floats ungrounded in today's financial economy.The paper recommends that researchers in finance and accounting adopt paradigms from literary theory, semiotics, linguistics, and semiology rather than continue to rely on economics-based theory, which has lost its power for explaining and predicting happenings in today's financial economy of self-referencing models and images.

关于提高印花税税率的冷思考

印花税税率调高会带来交易费用的上升,可以抑制短期投机,从而在一定程度上稳定市场。但在我国证券税制不完善的情况下,股票交易的印花税存在缺乏法律依据、税种错位、职能错位、征收范围错位等问题,其身兼数职,扮演了多税种合一的角色,仅靠调整印花税难以真正达到压缩股市泡沫、促进资本市场健康发展的效果,还会带来印花税其他职能的丧失。因此,开征差异性证券交易税,对印花税进一步改革已迫在眉睫。     

股票回购中内幕交易与股价操纵行为规制——由新《公司法》第一百四十三条引发的思考

新<公司法>增加了股票回购事由的条款,放宽了对股票回购的限制.但在股票回购的立法方面,总体上仍较为简单、粗略,缺乏具体的操作规则,没有形成完整、严密的规制体系.由于立法模式的差异,各国对股票回购过程中内幕交易及股价操纵行为的管制形式也有所不同.对欧美等国对股票回购过程中的内幕交易和股价操纵行为的监管进行比较分析,可以为我国股票回购实施过程中如何抑制股价操纵行为提供启示.     

Convenient estimators for the panel probit model: Further results

Bertschek and Lechner (1998) propose several variants of a GMM estimator based on the period specific regression functions for the panel probit model. The analysis is motivated by the complexity of maximum likelihood estimation and the possibly excessive amount of time involved in maximum simulated likelihood estimation. But, for applications of the size considered in their study, full likelihood estimation is actually straightforward, and resort to GMM estimation for convenience is unnecessary. In this note, we reconsider maximum likelihood based estimation of their panel probit model then examine some extensions which can exploit the heterogeneity contained in their panel data set. Empirical results are obtained using the data set employed in the earlier study. Helpful comments and suggestions by Irene Bertschek and Michael Lechner are gratefully acknowledged. This paper has also benefited from comments by two anonymous referees and from seminar participants at the Center for Health Economics at the University of York.

The impact of environmental regulation on productivity in German industries

The objective of this paper is to adjust a traditional total factor productivity (TFP) measure for the direct effect of environmental regulation on material and capital input. For this purpose we consider the fact that part of material input and pollution abatement capital have not been used to increase output but to cover the cost of using the environment as a factor of production. Therefore TFP growth rates are lower if part of the material input is allocated to abatement activities instead of producing output. We propose to treat compliance with environmental regulation as an unproductive input linked to the use of productive material input. Our aim is to answer and discuss two questions: How to measure the effect of environmental regulation on TFP, and does the effect matter. We examine data from 1975–1991 for ten pollution intensive German industries.We would like to thank Cornelia Oßwald for valuable research assistance. We are especially grateful to two anonymous referees for many helpful comments.

论我国资产证券化的风险防范

资产证券化存在着许多风险，尤其在我国，由于缺乏相关的法律法规、市场环境及中介机构，资产证券化的运行会蕴涵着更大的风险。必须充分认识这些风险并采取相应的措施，才能降低我国资产证券化的运行风险，促使我国资产证券化顺利进行。     

中华民族的伟大复兴，呼唤马克思主义及其经济学的指导

中国的经济快速增长，正在和平崛起，但中国目前仍是一个发展中国家，人均GDP较低。中华民族需要复兴，但这需要马克思主义及其经济学的指导。西方经济学有其不可克服的阶级局限性，它维护私有制而反对公有制，承认差别而不主张共同富裕，主张自由竞争而反对政府调控，维护发达国家利益而无视发展中国家利益，更无解决“三农”问题之策，等等。所以，我们必须坚持特别是要发展马克思主义及其经济学，当然还需注意吸收西方经济学的可取之处。公有制与市场经济的结合、公平与效率的协调、市场调节与宏观调控的关系、城乡关系、地区关系、政企关系、官民关系等一系列重大问题，都需要马克思主义及其经济学进一步作出科学回答。     

论人民币升值对世界证券市场的影响——以美国证券市场为例

我国是一个经济贸易大国,人民币升值将通过多种机制对世界证券市场产生重大影响.当然,由于不同的国家与我国的经贸关系和地缘关系不同,以及市场的开放和发达程度不同,相同的机制对不同国家的证券市场影响是不同的,这需要具体情况具体分析.鉴于人民币升值对世界证券市场的影响,我国应注意防范其中隐藏的风险,并尽可能地从中获取应得的利益.
