公共品供给中的政府责任

在公共品供给中,政府责任是提供它需要并且能够提供的公共品。需要提供的公共品是指在现有的资源技术条件下,达到社会效用最大化所需提供的公共品。能够提供的公共品是指征到拉弗曲线隐含的最大税收量所能提供的公共品。需要并且能够提供的公共品是指需要提供的公共品与能够提供的公共品中量较小的一方。通过比较政府实际提供的公共品与需要并且能够提供的公共品,可以评价政府在这一领域称职与否。     

超越契约理论--演化论视角的企业理论研究

企业的契约理论围绕交易成本概念解释了企业的存在、边界和内部组织,但严重忽视了企业的技术和生产功能,演化经济学的企业理论通过研究企业内知识的产生、传播和利用过程,以及组织与个人的交互学习,不仅重新解释了企业的存在、边界和内部组织问题,还研究了契约理论未触及的企业异质性、竞争优势和企业家等问题.     

Cost Structures and Nash Play in Repeated Cournot Games

This paper reports an experiment designed to assess the effects of a rotation in the marginal cost curve on convergence in a repeated Cournot triopoly. Increasing the cost curve's slope both reduces the serially-undominated set to the Nash prediction, and increases the peakedness of earnings. We observe higher rates of Nash equilibrium play in the design with the steeper marginal cost schedule, but only when participants are also rematched after each decision. Examination of response patterns suggests that the treatment with a steeper marginal cost curve and with a re-matching of participants across periods induces the selection of Nash Consistent responses.     

The Prosecution of Public Figures and the Separation of Powers. Confusion within the Executive Branch – A Conceptual Framework

Criminal investigation and prosecution of politicians, top civil servants and other public figures are topics frequently discussed in the media. The nature of the investigating or prosecuting authority varies between countries – from the general public prosecutor, through magistrates to independent counsels or parliamentary investigation commissions. This paper analyzes the role and status of public prosecutors within the separation of powers-concept. Prosecutors are usually part of the executive and not the judicial branch, which implies that they do not enjoy the same degree of independence as judges, and are ultimately subordinated to the directives of the minister of justice or the government. Conflicts of interest may hence arise if members of government can use the criminal process for their own or partisan interests. The incentives of public prosecutors in different jurisdictions are compared.     

Money as Social Exergy

Synopsis It has been proposed that open thermodynamic systems will act to dissipate available energy gradients by self-organizing into coherent structures that, with time, evolve and develop into nested hierarchies – panarchies – that adapt to internal and external changes according to a characteristic adaptive cycle. This paper seeks to apply these ideas in the purely societal realm by investigating the role of money in economic systems. Money represents the value embodied in goods; a value that is separate from the exact nature of those goods. We suggest that money thereby liberates the ‘free value’ of economic desire and that this free value has properties analogous to energy. The result is the self-organization of structures and systems (‘econosystems’) that dissipate this ‘free value’. Econosystems act at different scales, and nested levels of econosystems form a panarchy, having effects that can be observed. In particular, it appears that money facilitates the creation of relationships between econosystem actors, increasing the connectedness of the econosystems that envelop those actors. We have identified a phenomenon whereby freed social value (i.e. money) can aggregate, or pool, at a larger econosystem scale in structures such as banks. These pools act as gradients that actors at the neighborhood scale can exploit for self-organization in the econosystem. Thus, econosystem actors appear to be freed from thermodynamic constraints by using money as a means of self-organization. However, because of these pools of aggregated social exergy, connectedness is increased at the larger scale of the econosystem. The potential consequence of this dynamic is that money may act to push larger scale econosystems toward a state of heightened vulnerability to collapse, while freeing smaller scale actors from apparent constraints. In this way, we propose that money acts to skew information feedback loops between econosystem actors and larger scale structures such as economies and ecosystems.      

关于我国财政政策导向调整的研究

近年来我国实施的积极财政政策确实在很大程度上促进了经济和社会的发展。但是随着经济市场化程度的不断提高和经济环境的变化，这种积极财政政策也表现出诸多的不适应性。因此应适时调整财政政策导向以适应经济和社会发展的新要求。拟从我国近年来实施的积极财政政策的成效分析出发，阐述了当前调整财政政策导向的必然性，并提出了今后我国财政政策的调整方向。

Economic Potential of Biomass Based Fuels for Greenhouse Gas Emission Mitigation

Use of biofuels diminishes fossil fuelcombustion thereby also reducing net greenhousegas emissions. However, subsidies are neededto make agricultural biofuel productioneconomically feasible. To explore the economicpotential of biofuels in a greenhouse gasmitigation market, we incorporate data onproduction and biofuel processing for thedesignated energy crops switchgrass, hybridpoplar, and willow in an U.S. AgriculturalSector Model along with data on traditionalcrop-livestock production and processing, andafforestation of cropland. Net emissioncoefficients on all included agriculturalpractices are estimated through crop growthsimulation models or taken from the literature. Potential emission mitigation policies ormarkets are simulated via hypothetical carbonprices. At each carbon price level, theAgricultural Sector Model computes the newmarket equilibrium, revealing agriculturalcommodity prices, regionally specificproduction, input use, and welfare levels,environmental impacts, and adoption ofalternative management practices such asbiofuel production. Results indicate no rolefor biofuels below carbon prices of $40 perton of carbon equivalent. At these incentivelevels, emission reductions via reduced soiltillage and afforestation are more costefficient. For carbon prices above $70,biofuels dominate all other agriculturalmitigation strategies.     

公众参与城市绿色空间管理维护 ——以坦纳斯普瑞公园为例

“公众参与”广泛应用于以美国为代表的西方现代景观规划设计领域。随着社会的发展在美国等国相继出现“公众参与”城市绿色空间管理维护的趋势，人们逐渐意识到管理维护对城市绿色空间的重要性。以美国波特兰市坦纳斯普瑞公园为典型案例，通过实地调查、文献研究、访谈、归纳推理等研究方法，从公园建设背景、设计特色出发，回顾“公众参与”前管理维护的困境，阐述“朋友和伙伴”项目的发展历程、工作内容及成效，总结“公众参与”后期维护管理的意义，分析成功推行的原因。“公众参与”有助于解决目前中国城市公园管理维护面临的投入资金不足、游人素质偏低等问题，对未来城市公园管理工作的发展具有重要启示意义。     

体制变革背景下的服务业增长：一个定量分析框架

1978-2006年，中国服务业的高速增长与经济体制变革存在着直接的关系。体制变革是过去20多年中服务业增长的一个最重要因素。体制变革一方面通过放松管制提高了服务业占GDP的比重，另一方面，体制变革通过民营化进程降低了服务业的内部产业X-无效率，提高了服务业的金要素生产率。
