Testing for Stochastic Dominance Efficiency

We consider consistent tests for stochastic dominance efficiency at any order of a given portfolio with respect to all possible portfolios constructed from a set of assets. We justify block bootstrap approaches to achieve valid inference in a time series setting. The test statistics are computed using linear and mixed integer programming formulations. Monte Carlo results show that the bootstrap procedure performs well in finite samples. The empirical application reveals that the Fama and French market portfolio is first and second-order stochastic dominance efficient, although it is mean–variance inefficient.     

Forecasting lead times with economic data

Procurement lead time estimates are critical factors in production planning; however, they are generally based on a buyer's experience. The Westinghouse Corporation developed a linear model which successfully predicted procurement lead times for hot and cold rolled steel. This paper discusses nine models which use utilization and inventory data to predict lead time planning factors for aluminum, magnesium, steel and titanium products. The Lockheed-Georgia Company, which produces aerospace products, provided data for this research. The functional form of the models is significant and suggests that a nonlinear transformation of utilization based upon simple queueing models is a significant predictor of lead time duration.     

On the moment generating functions for integer valued random variables

Abstract

In this note, we give explicit expressions of moment generating functions for integer valued random variables in both univariate and multivariate cases, which extend the results obtained by Nadarajah and Mitov [Communications in Statistics–Theory and Methods, 32, 2003, 47–60] and more recently by Chakraborti, Jardim and Epprecht [The American Statistician, 2017], Kwong and Nadarajah [Communications in Statistics–Theory and Methods, 2017]. Some examples are also discussed.     

Combinatoric classification of multivariate normal variates

Consider classifying an n × I observation vector as coming from one of two multivariate normal distributions which differ both in mean vectors and covariance matrices. A class of dis-crimination rules based upon n independent univariate discrim-inate functions is developed yielding exact misclassification probabilities when the population parameters are known. An efficient search of this class to select the procedure with minimum expected misclassification is made by employing an algorithm of the implicit enumeration type used in integer programming. The procedure is applied to the classification of male twins as either monozygotic or dizygotic.     

P(n,3)的两个新公式

本文得到p(n,3)的两个新公式,若仅从计算的角度上来看,比原有公式快捷一些.另外,从本文的公式出发,可大大简化推导P(n,4)的工作.     

关于改进上市公司控制模式的探索

当前解决国民经济与证券市场的深层次矛盾的关键是:将上市公司的国有股表决权证券化为类似于股票一样的国有股表决权证,并在沪深股市竞价发行后流通交易,与原有流通股一起共同构成统一的公司控制权市场。以经济管理中的核心思想———权力制衡思想为指针,改进国家对公司的控制模式,制定《国有股被动表决权行使法》,分离主动表决权与被动表决权,政府只以否决权方式行使有关政治、产业政策方面的权利;而将有关资源配置方面的权利授予流通股公众,由流通股股东控制公司经营权,充分调动流通股东促进资源配置的积极性,形成国家依法监管与企业自主经营相结合的新型政企关系,找到公有制在市场经济中的微观实现形式。     

中国上市公司融资结构现状的实证分析

中国上市公司的融资结构具有自身的特征:债务融资比率相对较低,而流动性负债比率很高,企业债券市场很不发达。这与企业融资理论的最优融资顺序安排是矛盾的。本文对形成这种现状的原因作了分析,并针对这种现状带来的问题,提出了相关的政策建议。     

上市公司独立董事制度的重构

1997年以来,独立董事制度在中国的上市公司中已经开始铺开,但是,独立董事制度并没有发挥出其应有的作用。问题究竟在哪里?文章从独立董事的产生背景与现状出发,分析其中的独立董事选举与独立董事报酬支付问题,并试图重新构思适合本土化的独立董事制度.
