A new continuous distribution and two new families of distributions based on the exponential

Recent work on social status led to derivation of a new continuous distribution based on the exponential. The new variate, termed the ring(2)-exponential, in turn leads to derivation of two closely related new families of continuous distributions, the mirror-exponential and the ring-exponential. Both the standard exponential and the ring(2)-exponential are special cases of both the new families. In this paper, we first focus on the ring(2)-exponential, describing its derivation and examining its properties, and next introduce the two new families, describing their derivation and initiating exploration of their properties. The mirror-exponential arises naturally in the study of status; the ring-exponential arises from the mathematical structure of the ring(2)-exponential. Both have the potential for broad application in diverse contexts across science and engineering. Within sociobehavioral contexts, the new mirror-exponential may have application to the problem of approximating the form and inequality of the wage distribution.

Productivity and Welfare

Technical change is generally characterized by a rate and biases, both evaluated for given producer prices. This paper examines the potential discrepancy between this rate and the corresponding rate of consumer welfare change as measured by Allais distributable surplus. We postulate a general equilibrium context with various market failures (taxes, quotas, imperfect competition, and “poorly priced” commodities), and use comparative statics to express the rate of welfare change in terms of the rate and biases of the technical change. An elementary simulation model of a taxed economy suggests that the rate of welfare change may differ from the rate of technical change by as much as 50% under plausible circumstances.     

基于成熟度模型的化工物流业(CL-CMM)研究

借鉴软件能力成熟度模型（CMM）,构建了化工物流业成熟度模型（CL-CMM）。将物流企业成熟度分为初始期、成长期、成熟期、成熟巩固期、成熟创新期;从分析各个等级的关键过程,为化工物流业发展提供决策依据。并用成熟度曲线表示了化工物流业发展所经历的过程。     

基于价值工程理论的房地产性价比确定

高性价比已成为房地产开发商和消费者共同追求的目标,然而长期以来性价比都只是定性描述。本文建立了房地产性能评价指标体系,并应用价值工程理论构建了房地产性价比的确定模型,将其定量化,最后通过一个案例进行了说明。     

Binary effectivity rules

A social choice rule (SCR) is a collection of social choice correspondences, one for each agenda. An effectivity rule is a collection of effectivity functions, one for each agenda. We prove that every monotonic and superadditive effectivity rule is the effectivity rule of some SCR. A SCR is binary if it is rationalized by an acyclic binary relation. The foregoing result motivates our definition of a binary effectivity rule as the effectivity rule of some binary SCR. A binary SCR is regular if it satisfies unanimity, monotonicity, and independence of infeasible alternatives. A binary effectivity rule is regular if it is the effectivity rule of some regular binary SCR. We characterize completely the family of regular binary effectivity rules. Quite surprisingly, intrinsically defined von Neumann–Morgenstern solutions play an important role in this characterization.

我国企业财务管理目标的现实选择

随着会计国际化进程的进一步发展，传统的财务管理已远不能适应现代企业管理的需要。企业要想在激烈的市场竞争中得以生存和发展，就必须适应现代企业制度的要求，进一步加强企业财务管理，而其首要问题是必须树立现代企业财务管理的总目标。     

基金业绩、基金经理更换与投资者财富效应——一项基于我国资本市场的实证研究

从基金管理公司内部的委托—代理关系出发,以封闭式基金为研究对象,从基金经理调整现状、基金业绩与基金经理调整的关系、基金经理调整公告的市场反应三个方面,对基金经理变动进行了实证分析。研究发现:基金业绩确实对基金经理更换及更换后的去向具有一定的参考价值,但基金经理更换并没有使更换经理后的基金业绩显著改善;基金经理公告确实引起了基金市场价格的变动,但没有使基金投资者的财富显著增加。
