论法经济学建立的经济学基础

法经济学体系的建立,依赖于两大理论作基础,一是经济学理论,二是法理学基础。在经济学方面,古典自由主义的经济学说为法经济学提供了思想武器,新古典经济学为法经济学提供了重要的理论基础,新制度经济学则直接为法经济学提供了方法论基础。     

法经济学：法学和经济学半个世纪的学科交叉和融合发展

法经济学至今已经走过了近半个世纪,法经济学的发展不仅表现为经济学与法学的跨学科交融和经济学的研究范式对传统法学的巨大冲击与整合,也表现为其对司法实践的重要影响。文章通过对这一研究领域文献资料的整理,梳理出了学科发展的理论脉络和演化逻辑,可以为国内研究者的法经济学规范化和本土化的理论探索提供线索。首先,文章在对法经济学理论与实践的回顾与总结基础上,对该学科的性质、基本理论及研究方法做一简单的描述与总结;然后,选择法经济学研究中最重要且最受关注的财产、合同、侵权及犯罪四个领域,对其国内外研究现状,尤其对20世纪80年代后,国内学者对法经济学在中国的本土化研究加以详细的梳理与评述;最后,在对法经济学的成就与不足的总结与评述基础上,结合20世纪90年代后法经济学的学科演变趋势,提出了对法经济学未来发展趋势的基本判断。     

Behavioral Objectives and Student Learning Contracts in the Teaching of Economics

The authors present a series of writing assignments that teaches students how to evaluate and critique the written economic work of others. The foundation text is McCloskey's (2000) Economical Writing. The students' dialogues with McCloskey, with each other, and with the authors of the pieces they evaluate sharpen their understanding of, and ability to use, language as an instrument of economic thought. Interviews with former students identify specific benefits from the student perspective of this approach. The authors show how the assignment series can be modified in several ways and how the general approach, as well as the foundation text, can be used in different economics courses.     

新古典经济学及公司合同理论质疑

以新古典经济学为基础,波斯纳对法律制度进行了全面的经济分析。而伊斯特布鲁克和费希尔则是公司法经济分析的代表。其缔造的公司合同理论,贯彻了市场本位的价格理论,认为公司是合同的联结,法律制度无关紧要。新古典经济学及公司合同理论远离经济现实,受到新制度经济学及其他学派的挑战。     

法经济学的现实主义溯源

第一次法经济学运动是从两奈主线展开的：旧制度经济学和法学现实主义。从进步主义时代的经济学家对经济学自由主义的批判,到旧制度经济学对经济学形式主义的攻击,都凸显了对现实的关注和制度的探究。康芒斯对“财产”与“财产权利”的区分及对“交易”概念的一般化为科斯的交易成本理论和科斯定理架起制度和交易成本、新古典理论和法律经济学之间的桥梁提供了基础;对现实主义法学来说,无论是霍姆斯的“法律的生命是行动,而不是逻辑”的主张,还是庞德提出的“书本上的法”与“行动中的法”差异的观点都着眼于瓦解和攻击法学教条主义和形式主义的法学自足性,从而努力弥合法律理论和法律实践的鸿沟。其价值在于引入外在的视角来研究法律,从而使得经济学有可能成为法学分析中有力的外在视角。     

On the Economics and Scope of Implicit Pension Debt: An International Perspective

This paper examines the concept and scope of unfunded public pension liabilities, or implicit pension debt (IPD), from an international perspective. First, the paper discusses the importance and public finance background of IPD. Second, it presents and compares different methods for estimating IPD. Third, it provides international estimates of IPD based on accrued-to-date or termination liability methods with consistent assumptions across all countries using the World Bank's ``Pension Reform Options Simulation Toolkit' (PROST) computer model. The policy conclusions stress the need for standardized international reporting of this indicator.     

Rethinking the Costs of Economic Growth. Association for Social Economics Presidential Address, 2008

The source of economic development and growth is specialization in the context of comparative advantage. Growth in capital and other inputs, energy use, and technological change are insufficient to explain the magnitude of growth. Earlier critics of economic growth failed to connect growth to specialization, and so were distracted by nostalgia and sentiment. The specialization process itself produces three significant problems. First, as economies become more specialized, they become less flexible. Second, diversity tends to make ecological systems more robust, while specialization weakens them. Third, specialization produces social isolation. Solutions to these problems may be found in participatory, indicative planning.     

The Law and Economics of Costly Contracting

In most of the contract theory literature, contracting costsare assumed either to be high enough to preclude certain formsof contracting or low enough to permit any contract to be written.Similarly researchers usually treat renegotiation as eithercostless or prohibitively costly. This article addresses themiddle ground between these extremes, in which the costs ofcontracting and renegotiation can take intermediate values andthe contracting parties can themselves influence these costs.The context for our analysis is the canonical problem of inducingefficient relation-specific investment and efficient ex posttrade. Among our principle results are: (i) The efficiency andcomplexity of the initial contract are decreasing in the costto create a contract. Hence the best mechanism design contractscan be too costly to write. (ii) When parties use the simplercontract forms, they require renegotiation to capture ex postsurplus and to create efficient investment incentives. In somecases, parties want low renegotiation costs. More interestingis that, in other cases, parties have a strict preference formoderate renegotiation costs. (iii) The effect of contract lawon contract form is significant but has been overlooked. Inparticular, the law's interpretive rules raise the cost of enforcingcomplex contracts, and thus induce parties to use simple contracts.Worse, the law also lowers renegotiation costs, which furtherundermines complex contracts and is also inappropriate for someof the simpler contracts.     

立法成本的法经济学分析

立法成本的法经济学分析目的是为提高法律的适用性和经济效益,法经济学的成本效益分析方法给立法工作提供了崭新的视角及审视问题的方式。在立法中真正确立成本效益观,优化立法资源,加大立法投入,提高立法质量,才能真正达到立法的预期目的。     

Gordon Tullock and the Virginia School of Law and Economics

In 1999 Gordon Tullock became Professor at the George Mason University Law School. Tullock’s arrival at George Mason brought the economics department and the law school close together. The work that resulted during those years consolidated the methodological foundations for a different way of thinking about the economic analysis of law—the “functional” approach to law and economics. The functional law and economics approach espoused by the Virginia School was not attacking any of the results of the Chicago School or the Yale School, but rather proposing a methodological shift. This paper presents some of the results developed by this school and illustrates Tullock’s controversial positions on trials and on the common law system, through anecdotes, Tullock’s own work and related scholarly contributions.
