美、德农业社会化服务提供的启示

美国的农业社会化服务主要由三个部分组成：农业公共服务体系、集体农业服务体系和私人农业服务体系。公司＋农场、公司＋农户以及合作供销是美国农业社会化服务的三种形式。德国的农业社会化服务体系在于农业专业合作社组织的成功发展,尤其是健全的农村金融服务体系,由一个具有三级层次结构的分权型组织组成,通过立法和提供一些优惠政策,政府在服务体系中起了重要作用。我国农业社会化服务体系的组成和服务形式与美、德十分相似,在推动农村经济发展方面却有一定差异,美国和德国农业社会化服务的经验对中国农业社会化服务的发展具有重要启示。

Towards a complete real-time electricity market design

The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices, if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission. The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.      

Environmental Valuation with Imperfect Information The Case of the Random Utility Model

This paper considers welfare analysis with therandom utility model (RUM) when perceptions ofenvironmental quality differ from objectivemeasures of environmental quality. Environmental quality is assumed to be anexperience good, so that while perceptions ofquality determine choices, ex postutility is determined by objective quality. Given this assumption, I derive a measure ofthe welfare impact of changes in environmentalquality, and I show how this new welfaremeasure differs from the traditional welfaremeasure developed by Hanemann (1982). This newwelfare measure provides an approach tomeasuring the value of information aboutenvironmental quality within the framework ofthe random utility model.     

Ambient Taxes Under m-Dimensional Choice Sets, Heterogeneous Expectations, and Risk-Aversion

We consider the design of ambient taxes forrisk-neutral and risk-averse polluters whenpolluters and the regulatory agency haveasymmetric information about environmentalrelationships and probabilities associatedwith random events. Unlike prior work, we showthat under these conditions, optimal ambienttaxes must be firm-specific, and accompaniedby additional incentives to influencepolluters' choices of abatement techniques.

财政补贴改革刍论

财政补贴是国家宏观调控的杠杆之一,但是,目前补贴不规范,财政补贴数额大、项目繁杂,补贴效果‘异化’,加大了社会不公。为了强化财政补贴杠杆功能,提高财政补贴效益,必须按照建立公共财政的要求,本着满足公共需要原则、弹性补贴制度原则和补贴方式间接化原则,改变“一刀切”和补贴刚性的局面,确保采暖费收支合理化,取消肉食、副食品、粮食等价格补贴,改革国有企业的亏损补贴制度。     

高职院校教学体系改革的思考

高职院校应以培养高级技术应用型专门人才为目标,建立具有自身特色的教学体系。首先要通过广泛的社会调研,了解相应的人才需求,在此基础上制定适宜的教学计划;同时要着力构建与高职教育相适应的教学体系,教学模式与方法尽量适应高职学生的特点和培养目标,加大实践教学的比重,建立设备较先进、具备实训教学功能的综合训练教学基地,加强"双师型"教师队伍建设,以培养出真正符合社会需求的、高质量的技术应用型人才。
