On the Politics of Calculative Devices

This article examines the politics of calculative devices in one of the most successful areas of finance, the life insurance business. By empirically tracing an insurance applicant's risk trajectory, it analyses how calculative devices perform insurance underwriting through acting on insurance risk decisions. This allows one to document what calculative devices exactly do, and to point out the political effects of what they do. First, it highlights the fact that, contrary to thinking in terms of ‘the insurance logic’, there are multiple ways of calcuting life insurance risks. Second, it underscores the crucial role of calculative devices in that process by demonstrating how they align considerations as divergent as economics and medicine to perform a life insurance market. It then demonstrates the political effects of these calculative devices by making explicit how the latter contribute to the production of inequalities in calculative power in life insurance. In this way, the article links up insights from the performativity approach in the sociology of markets with the broader question of governing economic life. Such an approach, it is argued, provides the opportunity to open up the organization of economic markets and to put classic questions of justice and power struggles in economic markets on the agenda again.     

国际资本流动对中国股市的影响

判别国际资本市场波动时我国的冲击路径,防范国际金融风险冲击是维护国家金融安全的重要前提.国际资本流动、信息跨境传递以及投资者情绪的相互影响均可能在国家间传导金融风险.本文运用多元GARCH模型(BEKK)实证检验了美国资本市场波动和人民币汇率变化对我国资本市场的冲击传导关系,进而判别国际资本流动是否会对我国资本市场形成冲击.实证结论表明:汇率市场的风险波动程度显著低于资本市场,且美国资本市场与人民币汇率、我国资本市场与人民币汇率均存在显著的双向“风险溢出”效应.由此可以推断,国际资本市场风险通过国际资本流动的途径对我国市场形成冲击的事实.     

"小银行优势"在中小企业信贷市场的实证检验——基于中小板上市公司的经验证据

学术界对"小银行优势"假说的研究结论不同.本文选取我国154家中小板上市公司,利用其2006~2009年的贷款数据,通过分析不同规模的银行对中小企业贷款的特征,实证检验"小银行优势"假说在我国是否成立.研究结果发现,经营风险低,资产规模、生产规模和人员规模大的企业,更有可能成为大银行的贷款对象;而从小银行贷款的企业,主要依靠与银行的稳定关系,其贷款来源的银行数目较少.因此支持了"小银行优势"假说.     

浙江省部分高校学生体育消费调查

运用问卷调查、献资料、访谈、数理统计等，对浙江省大学生的体育消费结构水平、体育消费动机等方面进行了调查、分析，认为浙江省大学生已具有较强的健身意识和体育消费观念，但消费总体水平较低；大学生的实物消费水平明显高于劳务消费水平，体育消费支出的内容还比较单一；大学生体育消费水平跟生活消费支出的水平成正相关，其中，劳务消费水平的增长幅度比实物消费水平的增长幅度更大；男、女大学生的体育消费动机存在明显差别。     

On the return of art investment return analyses

We survey more than twenty studies estimating rates of return of investments in single art objects and whole collections and evaluate the various approaches to art price movements taken so far. The majority of the estimates find lower returns for investments in art objects than for investments in financial assets. However, most existing analyses are restricted to auction data and neglect transactions cost and taxation. They partly focus on mechanistic calculations and disregard the distinguishing institutional and behavioral characteristics of art markets. We look into the possibilities to capture and empirically estimate psychic returns from owning art.     

论后汽车市场应用型人才学历提高的客观性与必要性

我国汽车运用技术人才的培养主要依靠中等职业教育，而高等教育相对薄弱。我国现行的高等教育基本上是学科型教育，重视理论的系统性、完整性，对学生实践动手能力的培养重视不够，而技工学校虽然重视基本技能的培养，但学生技能单一、理论素养薄弱、发展后劲不足。因此提高后汽车市场应用型人才的学历教育非常必要。

A Generation Pricing Method with Capacity Bidding

Due to historic reasons China encounters some special difficulties in ESI(electricity system industry) restructureing,An easy and simple electricity value equivalent(es-EVE) method for day-ahead pool purchase pricing of China is therefore presented in this paper.The es-EVE method is different from two-part and one-part tariffs.It is more like the UK‘s method in form,but revised for China with some new concepts and procedure.The main contributions of it include:(1) Find two kinds of eigenvalue,namely EVEs,in an optimization model.(2) Define new concepts of virtual units units and feasible region,(3) Twice merit orderings are employed successively to find marginal price.They are simple maximum and minimum comparison procedures and so on.The special economic significance of the method for China is discussed.and some suggestion for ESI Restructuring based on es-EVE method are provided.A case study is offered at the end of the paper.
