Regulating an externality-generating public utility: A multi-dimensional screening approach

In this paper, I present a monopoly screening model in which a firm holds private information on fixed abatement costs. Because of the nature of the optimal contracts, bunching is never optimal even with ‘n’ distinct types. A characterization of full and limited information solutions is offered and it is shown that the design standards alone determine the value of an information rent. The variable charge is completely free of any marginal information costs. This allows the variable charge to track marginal damages and thereby ensures that marginal social costs are covered. A fixed charge implements the optimal solution.     

A Stochastic Frontier Production Function with Flexible Risk Properties

This paper considers a stochastic frontier production function which has additive, heteroscedastic error structure. The model allows for negative or positive marginal production risks of inputs, as originally proposed by Just and Pope (1978). The technical efficiencies of individual firms in the sample are a function of the levels of the input variables in the stochastic frontier, in addition to the technical inefficiency effects. These are two features of the model which are not exhibited by the commonly used stochastic frontiers with multiplicative error structures.An empirical application is presented using cross-sectional data on Ethiopian peasant farmers. The null hypothesis of no technical inefficiencies of production among these farmers is accepted. Further, the flexible risk models do not fit the data on peasant farmers as well as the traditional stochastic frontier model with multiplicative error structure.

会计计量与企业债券信用评级关系的应用分析——基于2006年新会计准则的思考

企业债券信用评级是企业发行债券的重要步骤,债券评级对会计信息具有依赖性,而会计信息的计量属性会直接影响会计信息,不合适的会计计量属性会对债券评级造成负面影响。本文结合2006年的新会计准则的相关规定和企业债券信用评级的特点,通过分析会计计量对信用评级的误导因素,认为借鉴国际先进经验,可以提高债券评级的可靠性和客观性,促进企业融资市场的公平性和公正性。     

上海A股市场股价波动相互影响能力实证研究

股票市场中股票价格的波动是相互影响的,但不同的股票其价格波动时对其他股票价格行为的影响能力是不同的。本文通过对我国上海A股市场的实证分析表明,有少数股票其价格波动时对其他股票价格行为有很强的影响能力,而大多数股票的这种影响能力很小。此外,单个股票价格波动时引起其他股票价格涨、跌的能力一般都有显著差异。     

An instrumental variable approach for panel unit root tests under cross-sectional dependence

For dynamic panel models with cross-sectional dependence, several unit root tests are constructed using a Huber-type instrument, whose null asymptotics are standard Gaussian and do not depend on nuisance parameters. A Monte-Carlo simulation shows that the proposed tests have better sizes and comparable powers relative to other two existing tests developed for cross-sectionally dependent dynamic panel models.

Are There Differential Effects of Price and Policy on College Students’Drinking Intensity?

This article investigates the impact of campus bans on alcohol use and the price of alcohol on college students'drinking intensity. The impact of a campus ban on drinking appears to depend on the ability of students to substitute off-campus access to alcohol for on-campus access. Where few off-campus alternatives exist, campus bans reduce the odds that a student becomes a heavy drinker but have no impact on the odds of transitioning from abstainer to drinker. Where off-campus alternatives are more plentiful, campus bans are less effective. Increasing the price of alcohol appears to be equally effective at reducing the likelihood of drinking and heavy drinking. (JEL)     

技术差距模型与中非合作的利益分配

近年来,随着中国经济实力的增强和非洲国家经济贸易地位的提升,中非经贸关系发展迅速.双方经济联系趋向紧密,意味着发生经济摩擦的几率加大.最近两年,一些非洲国家与中国的贸易争端有增长之势,成为一些西方舆论制造"中国新殖民主义"的口实.本文运用技术差距国际贸易模型,分析了中非合作在国际贸易利益分配方面的动态变化,旨在为反驳"中国新殖民主义"论提供一定的理论支持,同时提示中国在合作中须保持一定的技术优势.
