基于古诺模型的四种市场的社会福利

市场根据垄断程度的不同。可以分为完全竞争、垄断竞争、寡头垄断和完全垄断市场四种类型。基于古诺模型，用博弈论方法研究n个厂商市场情形的总产量、价格、总收益和消费者剩余并把它们归纳为统一的公式。从四种市场情形总产量和价格的特点推出其供给曲线的形状，进而比较其社会福利的状况。研究结果表明，随着垄断性的加强，市场的社会福利会越来越劣，完全竞争市场的社会福利最好，垄断竞争市场次之，寡头垄断市场更次，完全垄断市场的社会福利最差。     

反倾销税与反倾销补贴的经济学思考

文章从经济学角度分析一国采取反倾销税时对该国经济福利的影响,同时使用反倾销补贴的新概念并与之比较。文章对两国厂商在几种不同的成本情况下分别采取反倾销税和反倾销补贴时对本国经济福利会产生怎样的影响进行对比分析。采取反倾销补贴与反倾销税相比较能带来更大福利,反倾销补贴可以更大程度地防止反倾销的滥用,而且可以更有效地阻止掠夺性倾销。     

Premium setting and bank behavior in a voluntary deposit insurance scheme

This study analyzes the effect of premium rates on banks’ incentives to join a deposit insurance scheme and their incentives to invest in risky projects under a voluntary deposit insurance scheme. We find that in order to maximize social welfare, the insurance agency must either set the premium rate to be low so as to attract all banks to join the insurance scheme, or not to have the deposit insurance at all. However, the low premium rate in the voluntary scheme does not balance the budget of the deposit insurance. We also show that in the compulsory deposit insurance scheme, however, it is possible to impose an optimal premium rate that can balance the insurance agency’s budget and achieve the highest social welfare. The results also present the dominance of the compulsory scheme over the voluntary scheme in terms of maximizing social welfare and balancing the budget.

因行业而异的温室气体减排政策——基于古诺模型的福利分析

笔者在古诺模型中引入温室气体排放的负外部性问题,分析了厂商的利润最大化行为,并基于社会福利函数得到了温室气体最优排放水平。该最优结果与经典的庇古分析结果相比偏多,这表明庇古政策并不是最优的,最大化社会福利的排放额并无需完全弥补排放的负外部性。进一步分析表明,最优排放水平与市场结构有关,垄断程度越高减排水平反而应该越低。     

私利与公益的协调是可能的吗——斯蒂芬·杨“道德资本主义”经济伦理观解析

经济伦理学要追求私利与公益的和谐的、协调的统一。斯蒂芬.杨提出以道德资本主义的经济伦理观来有效协调两者的关系,对人们颇有启发。道德资本主义提倡将私利投入公益,践行者要有＂考虑整体的自我利益＂的意识。现实经济生活中有效地结合了私利与公益的成功企业,对于终结贫困的重大价值,道德资本主义本身所具有的最佳结合了超越性之理想与现实性之欲念的特点等为道德资本主义提供了可能性。考克斯原则是目前全球范围内践行道德资本主义的范例。但是,道德资本主义要真正落到实处还必须大力培养有原则的商业领导。

基于社会保障理论的孤残儿童福利研究

目前社会救助保障制度已基本覆盖浙江省孤残儿童,大部分孤残儿童享受养育、医疗、康复、教育等方面的优惠政策,基本权益得到有效保障。但是,孤残儿童保障政策制定和实施、儿童福利机构的建设也存在一些问题。应加强各部门之间的组织协调,合力推进儿童福利事业发展;出台儿童福利保障政策,建立完善新型孤残儿童福利体系;加强儿童福利机构自身建设,提升可持续发展能力;积极稳妥推行家庭寄养工作;加强舆论宣传,弘扬爱心助残助孤义举,推动孤儿福利事业与慈善事业共同发展。     

The value of nonindigenous species risk assessment in international trade

Managing the introduction of nonindigenous species is becoming a major goal of policy-makers at regional, national and international scales. Here we investigate, at the national level, the ideal design and expected net benefits of a risk assessment program for evaluating the desirability of nonindigenous species imports. We show how to enhance the statistical rigor of such a system by correcting a common non-random sampling problem encountered in the data. This correction enables model output to be interpreted in an economically relevant way and facilitates a theoretically rigorous characterization of the balance between trade and nonindigenous species establishment risk. Using reptiles and amphibians imported to the U.S. as a case study, we characterize economic outcomes over a range of cases and demonstrate substantial expected returns to such a screening program, relative to the current effectively open-door policy. Our results are informative for the current debate in the U.S. about whether to require federal agencies to apply risk assessment before allowing a species for import. The framework presented decomposes a complex argument about risk management into component economic and statistical parts, allowing for debate and improved understanding over each element to inform the overall program in a transparent fashion.     

Marketing and society: Preface to special section on volunteerism, price assurances, and direct-to-consumer advertising

We discuss the reasons why this call for papers was issued and describe the process of selecting the three articles presented in this special section. We argue that maximizing stakeholder welfare and not just consumption maybe a new goal for marketing that will be consistent with emerging societal trends. Three articles on volunteerism, price assurances, and direct-to-consumer advertising result from our call and are presented in this section. This introduction is an overview of the three articles.
