Inferences on functions of Pareto parameters with application to income inequality measures

The Theil, Pietra, Éltetö and Frigyes measures of income inequality associated with the Pareto distribution function are expressed in terms of parameters defining the Pareto distribution. Inference procedures based on the generalized variable method, the large sample method, and the Bayesian method for testing of, and constructing confidence interval for, these measures are discussed. The results of Monte Carlo study are used to compare the performance of the suggested inference procedures from a population characterized by a Pareto distribution.     

C330. The variability of evaluations of speculative ideas

This article reports results of an extensive simulation study which investigated the performances of some commonly used methods of estimating error rates in discriminant analysis. Earlier research papers limited their comparisons of these methods to independent training data. This study allows for a simple auto-regressive dependence among the training data. The results suggest that the estimation methods based on the normal distribution perform adequately well under conditions of negative or mild positive correlation in the data, and small dimensions (p) of the observation vectors. For large p or strong positive correlation structures the conclusion is that one of the better non-parametric methods should be used. Special circumstances and conditions which notably affect the relative performances of the methods are identified.     

研究生培养政策70年:演变逻辑与发展走向

新中国成立70年来，我国研究生培养政策经历了初创起步、推进发展、稳步延伸和调适深化四个发展阶段。在演进逻辑上，凸显出国家需求与市场诉求的权衡性、培养目标注重个人成就与社会发展价值的双维导向、培养质量保障体系趋向质量和效益二维共进等特征。研究生培养政策是个动态发展系统。随着时代的发展和变迁，应在政策制定和发展的动力机制、政策目标的价值导向、政策执行的监督评价及保障决策等方面作出适时调整。     

Business reform outcomes: Why so different?

Post-crisis policy making increasingly focuses on doing business reforms. We argue that the effects of those reforms will be different across countries. To understand the reasons for the reform outcome divergence, we advance a novel firm-size distribution (FSDs) argument. At the center of the argument is the fact that FSDs are different across countries and stable over time. Then, if a given doing business reform induces firms of different size to grow differently, this will produce a variety of reform outcomes across countries. To advance the argument, we set up a tractable general equilibrium (GE) model and study how firms of different size grow after a doing business reform. The model predicts that larger firms will grow faster than smaller firms after the reform. The model predictions are tested on the Enterprise Surveys (ES) data, merged with the Doing Business indicators. We confirm that firms of different size grow differently after a Doing Business reform. Thus, based on the notable differences of firm size distributions across countries, identical reforms to start, operate and close a business will produce a variety of reform outcomes across countries.     

基于消费者显著性偏好的双边平台转换成本和定价策略研究

针对消费者对转换成本和价格属性具有显著性偏好的实际情况，基于显著性理论对垄断双边平台企业的转换成本和定价策略问题进行了研究。研究发现：1)在显著性偏好非对称型市场上，对价格敏感的一方收取的价格最低，对高转换成本的一方收取的价格最高，而在显著性偏好对称型市场上，平台的最优价格位于非对称型市场之间，但是对价格敏感型市场收取的价格低于转换成本敏感型市场的价格。2)在高转换成本的市场，平台利润最低；低转换成本市场平台利润最高，而混合型情况的最优利润位于这两者之间。该研究结论说明平台企业应该采取措施来降低用户加入平台的转换成本，从而增加利润，这与现实的案例研究结论相吻合。     

忠义之气：张齐贤对宋初儒学政治文化的构建及其政治实践

宋初倡导“名节”的思想在张齐贤那里得到了明确的贯彻。他宣讲的“忠义”观念成为宋代政治文化的核心规范意识。“忠义”作为一种思想规范对相当广泛的社会层面产生着约束力，成为传统社会士大夫阶层共同的心理定式，使之由过去对功名的孜孜追求，转向道德精神的弘扬。北宋立国之后，“忠义”作为政治思想的基本原则和政治道德的主体形态，在新的时代情境中得到了特别的强调。张齐贤的政治治理思想，体现在地方治理和对外谋略两个方面，而在此两个方面他都践履了自己所倡行的“忠义”理念。

基于优先权拍卖的产能分配机制研究

本文考虑一个供应商和两个独立零售商构成的供应链系统。当供应商的产能受到约束时，零售商可能会竞争有限的产能。本文提出将“优先分配权”作为一个有价值的标的物进行拍卖，按照出价高低确定优先分配顺序。本文证明了优先权拍卖机制属于共同价值模型，并提出了两类拍卖机制：事先拍卖和事后拍卖。本文证明两类优先权拍卖机制均会促使零售商提交真实的需求作为订单量，并且满足收益等价定理。而就供应商期望利润而言，事后优先权拍卖机制要高于事先优先权拍卖机制。
