论我国企业合并的反垄断控制

过度的企业合并会限制甚至消灭市场竞争,因此,保持市场的有效竞争需要反垄断立法。反垄断法合并控制应关注整 体经济效率;合并控制的实质性标准是产生或加强市场支配地位;而符合反垄断禁止标准同时又存在法定豁免事由的的合并有 可能会被批准     

Incentive Contract and Weather Risk

We study contracts designed to remunerate a farmer for the production of an ecosystem service with the payment dependent on the results of the farmer’s actions and on weather conditions. Two contracts are proposed: the first takes into account both the results of the farmer’s actions and a weather variable that reflects the actual atmospheric conditions during the life of the contract; the second bases the payment on the results alone incorporating only the average effect of weather. Social welfare is optimal when both the results and the specific atmospheric conditions are taken into account; however, this type of contract may be less acceptable to the farmer due to his perception of the level of risk involved.We thank two referees for valuable comments.     

Economic Valuation of Health for Environmental Policy: Comparing Alternative Approaches. Introduction and Overview

Protecting human health is a primary goal of environmental policy and economic evaluation of health can help policy-makers judge the relative worth of alternative actions. Economists use two distinct approaches in normatively evaluating health. Whereas environmental economists use benefit-cost analysis supported by monetary valuation in terms of willingness-to-pay, health economists evaluate interventions based on cost-effectiveness or cost-utility analysis (CEA), using quality-adjusted life-years (QALY) or similar indexes. This paper provides background on the controversy about the relative merits of these approaches and introduces the remaining papers in the special issue. These papers (with one exception) were presented at a conference sponsored by the Department of Economics at the University of Central Florida with support from the US Environmental Protection Agency. Although CEA might not lead to substantially different implications for environmental policy than benefit-cost analysis, and QALY may provide a benefit transfer tool to fill gaps in the morbidity valuation literature, the papers in this issue raise serious concerns about the suitability of QALY-based CEA for environmental regulatory analysis. QALY does not in general appropriately represent individual preferences for health and CEA is neither independent of income distribution nor adequate to assess efficiency.     

中国发展知识经济的空间结构

发展知识经济可以有效解决中国所面临的诸多挑战。文章探讨了经济发展的空间结构理论、城市与现代经济的关系、中国发展知识经济的路径选择,提出中国发展知识经济的空间结构是“升岛成陆”,即以各级有条件的城市特别是大城市为主先行发展知识经济,然后带动其它地区,扩大发展知识经济的区域,从而最终像地球科学中的升岛成陆造地运动一样,实现全国发展知识经济。同时,要通过行政区划制度创新促进这一进程,要将一些大城市升格为直辖市。     

对马克思按分配原则的反思

马克思的劳动价值论不仅是剩余价值的理论基础和分析资本主义分配的理论依据，同时也是马克思设想的社会主义按劳分配的逻辑起点。只是以往我们对按劳分配原则的最本质的含义理解不够透彻。实质上，应该说马克思设想的按劳分配原则最本质的内容包括三点，即在未来的社会主义社会中，个人消费品的分配以劳动量的大小为依据，等量劳动获取等量报酬，承认能力本位。在社会主义市场经济条件下的按劳分配原则，仍然没有偏离这三点本质的含义，但已经有了新的特点和形式。     

退耕还林（草）生态补偿实施现状与问题分析——以甘肃省定西市安定区为例

为了建立合理的国家生态补偿机制，了解现阶段生态补偿中存在的问题，我们运用PRA（Participatory rule appraisal）即参与性农村评估和传统的问卷调查相结合的方法，通过对研究区内生态建设补偿措施实施过程中的现状研究、问题分析，发现本区在实施退耕还林（草）生态补偿中的主要问题是仍然没有有效解决生态补偿的三个基本问题：补偿主体、补偿强度、补偿资金来源。生态补偿处于初级阶段，没有形成制度化、法律化，有必要在政策、法律层面建立比较完善的生态补偿机制。     

Non-commitment in performance evaluation and the problem of information distortions

Auditing is modeled in a sequential game without commitment. The manager must decide whether and where to audit a worker's output, taking into account all interim information he has obtained. The worker will work just hard enough (and show it) to divert the manager from making an audit or cover up, withholding information about his work to make an audit more difficult. This usually raises the costs of setting work incentives, so incentives are softened, sometimes drastically. Moreover, when a worker's on-the-job information is valuable for entrepreneurial decisions, work incentives must be softened to improve the internal flow of information.

金融监管效率的基石:激励相容的监管机制

本文通过金融监管过程中的博弈分析,揭示了当前的金融监管制度安排在信息不对称条件下导致的监管当局提供有效监管激励的缺失及金融机构普遍的道德风险是造成金融监管失灵的主要原因.因而解决金融监管低效率或失灵问题的关键,在于通过金融市场透明度建设、监管制度安排的合理设计及金融机构治理结构的完善,实现社会公众、监管当局、金融机构之间的激励相容.     

Tariffs,trade and unemployment in a disequilibrium model: issues and policies

This paper studies the disequilibrium transition process engaged by increased openness to trade, and the effect of institutions, market behaviors and economic policies on that transition. The issue is analyzed with a simple two country (north and south), two goods model, amended in order to take into account the time dimension of both the production and the decision processes. Investigating the consequences of a tariff decrease by means of numerical simulations, we show to what extent wage and price setting, and the degree of tightness of monetary policy affect the outcome of the disequilibrium process. The main result is that capturing the gains associated with international trade requires market behaviors and economic policies, which are rather different from what is usually prescribed.
