Marginal distributions of sequential and generalized order statistics

Expressions for marginal distribution functions of sequential order statistics and generalized order statistics are presented without any restrictions imposed on the model parameters. The results are related to the relevation transform, to the distribution of the product of Beta distributed random variables, and to Meijers G-functions. Some selected applications in the areas of moments, conditional distributions, recurrence relations, and reliability properties are shown. Key words:Order statistics; Generalized order statistics; Sequential order statistics; Record values; Distribution theory; Meijers G-function; Recurrence relations; Reliability properties.     

“林志玲现象”的商业密码 姿色+资质+姿态

<正>这是一个注意力经济的时代。美女经济是注意力经济中的典型。从经济学的角度上看,在以男性为主导的社会当中,美貌是女人的一种资本,可以被消费。如何将美貌这种资本转化为生产力,并将其经济效益最大化,是一门很深的学问。将这门学问学好,不仅对于美女本身带来收益,连带与眼球相关的产业同时也被带动,其商业价值不可限量。但是,随着经济的发展,社会形态的变化,传统的美女经济正经受挑战。最近的“林志玲现象”引起了我们对这种变化的关注。稀缺和偏好是经济学里最重要的两个概念。当一种资源是稀缺的而且满足效用(更现代的说法是被严格偏好),必然产生效益。“林志玲现象”是否符合该定律,我们来分析一下。     

试论非政府国际组织在国际经济法上的主体地位

非政府国际组织是否是国际经济法上的主体,是国际经济法应该解决的一个基本问题,晚近,有些学者主张非政府国际组织应当成为国际经济法上的主体,纳入国际经济法的调整范畴。本文从法理学的角度分析非政府国际组织不能成为国际经济法上的主体,并预测非政府国际组织随着自身对国际经济法的影响日益扩大,有可能演变为政府间国际组织,从而成为国际经济法上的主体。     

基于环境管理的企业绿色营销对策

环境管理与绿色营销是企业的新经营理念，其主要针对两个方面：一是防止生产经营过程中对环境的污染；二是在经营活动中保护生产经营资源。企业环境管理与绿色营销的基本对策是建立环境管理监控体系，采取开发绿色产品、提供绿色服务、争取绿色标志等环境管理和绿色营销措施。     

Insuring against the shortfall risk associated with real options

We would like to insure against the risk that a geometric Brownian motion, correlated with the price process of a certain traded asset, is in a set E at time T. In this paper it is shown that the best action one can take to insure against this risk is to buy a binary option on the traded asset. We give explicit formulas in the case that E is an infinite interval. The setting of all our investigations is the Black-Scholes model.

Representing complete and incomplete subjective linear preferences on random numbers

We show that preferences on random numbers which satisfy certain natural properties can be represented, in the setting of topological vector spaces, by a suitable family of continuous previsions which is, in a sense, unique. Moreover, for most commonly used spaces of random numbers, we establish that one can derive these preferences, via an expectation operator, from a suitable family of probabilities (whether or not finitely additive).

Reduced Form Auctions Revisited

This note uses the Theorem of the Alternative to prove new results on the implementability of general, asymmetric auctions, and to provide simpler proofs of known results for symmetric auctions. The tradeoff is that type spaces are taken to be finite.     

Human Capital and Growth Cycles

This paper studies the dynamic interaction between human capital accumulation and economic growth. Capital market imperfections and an indivisibility in human capital investment prevent poor agents from accumulating skills, the acquisition of which positively affects technological progress. More productive technologies in turn require more sophisticated qualification and involve higher training costs. The equilibrium dynamics can be characterized by the joint evolution of productivity growth, the schooling costs, and the income distribution. Under our assumptions, individual incomes follow a non-linear Markov chain. This non-linearity generates endogenous fluctuations of schooling activities and the rate at which productivity improvements occur. We thank an anonymous referee for many helpful suggestions.

Effective regulation versus tacit collusion in the long-distance market: an empirical analysis

Regulatory decisions often must be made in an atmosphere of uncertainty, and arguments presented by the affected parties frequently add to, rather than resolve, that uncertainty. Here, we examine several of the deregulatory decisions affecting the long-distance market that were rendered by the FCC over the two-decade period following the divestiture of AT&T. Our purpose is to provide empirical evidence relevant to some of the arguments regarding market conditions that were presented during that period. Findings suggest that some of the more prominent allegations are not supported by the data.
