A New Bargaining Set of an N-Person Game and Endogenous Coalition Formation

The two most fundamental questions in cooperative game theory are: When a game is played, what coalitions will be formed and what payoff vectors will be chosen? Few solution concepts or theories in the current literature provide satisfactory answers to both questions; answers are especially lacking for the first one. In this paper we introduce a new bargaining set, which is the first solution concept in cooperative game theory that provides answers to both fundamental questions endogenously.

加入WTO对铁路企业的影响

世界贸易包括货物贸易、服务贸易和技术贸易(知识产权)三方面内容。我国加入WTO以后,铁路将分三阶段开放货运市场。第一阶段,加入之际,允许外资参股中外合营铁路货运企业,外资比例不超过49％。第二阶段,加入WTO满3年后,允许外资在铁路货运公司中控股。第三阶段,加入WTO满6年后,允许设立外商独资的铁路货运公司,同时承诺开放与铁路货运有关的仓储和货运代理业务。这样铁路企业不

香港的知识产权管理保护及其对广东的启示

随着CEPA的签署实施，粤港两地在经贸、知识产权的合作更加紧密。香港的知识产权管理保护工作卓有成效且别具特色，与之毗邻的广东，应当借此契机向香港学习借鉴，取长补短。     

社会审计委托代理分析

本文分析了社会审计契约中委托代理关系及审计信息不对称表现及形成原因,通过建立社会审计的委托代理模型,揭示了在审计人和委托人均完全理性的假设下,委托人可以通过激励机制鼓励审计人尽最大努力完成工作。在此基础上分析了我国社会审计收费制度的不合理性、转轨经济环境下社会审计合约具有的不完全契约特性,并提出了改革的设想。     

A note on strategies for bandit problems with infinitely many arms

A bandit problem consisting of a sequence of n choices (n) from a number of infinitely many Bernoulli arms is considered. The parameters of Bernoulli arms are independent and identically distributed random variables from a common distribution F on the interval [0,1] and F is continuous with F(0)=0 and F(1)=1. The goal is to investigate the asymptotic expected failure rates of k-failure strategies, and obtain a lower bound for the expected failure proportion over all strategies presented in Berry et al. (1997). We show that the asymptotic expected failure rates of k-failure strategies when 0<b1 and a lower bound can be evaluated if the limit of the ratio F(1)–F(t) versus (1–t)^b exists as t1^– for some b>0.     

完善我国中小企业融资环境的思考

文章指出我国政府对中小企业的重视程度日趋增强,已陆续出台了一系列扶持中小企业发展的措施,但是目前我国中小企业融资难的问题并没有从根本上解决,资金缺乏仍旧是制约我国中小企业进一步发展的首要问题,其重要原因是我国中小企业融资的法律、政策、中小企业信用担保体系和其自身的组织管理体系仍不完善,且缺乏相应的融资社会服务体系,所以,当前加紧建立和完善我国中小企业融资环境已迫在眉睫。

Two-sample rank tests with truncated populations

LetX ₁,…,X _m andY ₁,…,Y _n be two independent samples from continuous distributionsF andG respectively. Using a Hoeffding (1951) type theorem, we obtain the distributions of the vector S=(S ₍₁₎,…,S _(n)), whereS _(j)=# (X _i ’s≤Y _(j)) andY _(j) is thej-th order statistic ofY sample, under three truncation models: (a)G is a left truncation ofF orG is a right truncation ofF, (b)F is a right truncation ofH andG is a left truncation ofH, whereH is some continuous distribution function, (c)G is a two tail truncation ofF. Exploiting the relation between S and the vectorR of the ranks of the order statistics of theY-sample in the pooled sample, we can obtain exact distributions of many rank tests. We use these to compare powers of the Hajek test (Hajek 1967), the Sidak Vondracek test (1957) and the Mann-Whitney-Wilcoxon test. We derive some order relations between the values of the probagility-functions under each model. Hence find that the tests based onS ₍₁₎ andS _(n) are the UMP rank tests for the alternative (a). We also find LMP rank tests under the alternatives (b) and (c).
