信用对服务业增长的影响：理论探讨与经验研究

本文首先通过超边际分析对信用促进服务业发展的机制进行形式化证明,然后利用包括32个OECD经济体与90个非OECD经济体在内的共122个国家或地区1997-2011年的数据,运用静态面板固定效应模型和动态面板FD-GMM估计方法,并按照全部样本、OECD样本与非OECD样本的类型进行经验研究,最后审查了研究结论在中国的适用性。结果发现：静态面板模型下,信用水平与服务业增长率显著正相关,这一结论对全部样本、OECD样本、非OECD样本都成立;动态面板模型下,信用对服务业增长的促进作用在全部样本与非OECD样本中仍显著,但是在OECD样本中不显著;信用推动服务业增长的边际生产力随着信用存量的增加而递减;信用是推动我国服务业增长的重要因素,且其边际生产力较高。     

城市再生水的边际机会成本定价方法研究

分析了边际机会成本定价法的特点,指出了该方法应用于城市再生水定价时的作用,给出了边际机会成本定价的一般公式.通过分析得出再生水边际成本定价时需用平均增量成本代替边际机会成本,并给出了平均增量成本的计算公式.最后提出了城市再生水边际机会成本定价的具体步骤.采用边际机会成本定价法可使再生水生产企业获得足够的收入去扩容并实现可持续发展,还有可能实现资源的高效分配,因此可作为判断再生水价格是否合理的一个主要依据.     

消费需求与收入分配结构的相关性

首先陈述了消费需求下降和居民收入分配差距拉大的事实,进而对两者的数量关系进行了证明。在此基础上,利用基尼系数和边际消费倾向等统计数据进行回归分析,探讨了我国居民收入分配差距拉大对全社会边际消费倾向下降的影响程度。最后,提出了几条缩小不合理的居民收入分配差距,以提高消费需求的政策建议。     

论宏观调控——对我国2003年来宏观调控的几点认识

界定了宏观调控的内涵,论证了宏观调控的必要性,讨论了宏观调控的类型,对宏观调控成效与政策实施时长进行了模型分析,并对学术界就我国2003年开始的宏观调控成效的争论进行了简要的述评。     

von Thünen: Capital,Production Functions,Marginal Productivity Wages,and the Natural Wage

This paper puts seminal contributions to theory of production functions and maximization of explicit quantitative objective functions by Johann Heinrich von Thünen into a systematic historical perspective. We show that his comprehensive ‘Tableau Economiques’ do imply two exact parametric production functions. Moreover, the renowned ‘geometric mean wage’ formula is restated as an exact CES marginal labor productivity wage for σ = 2. We review four alternative modes of normative (natural) wage calculations without an explicit production function, and conclude that von Thünen's natural wage differentiation formulas are bona fide alternatives for deriving the natural wage formula.     

持久性收入对中国农民消费影响分析

运用弗里德曼的持久性收入假说分析我国农民的消费问题,并利用计量经济学的方法对中国历年农民消费统计数据进行分析,得出“持久性收入及持久性收入的边际消费倾向对我国现阶段农民消费支出影响较大”的结论,并从增加持久性收入和提高持久性收入的边际消费倾向两个方面就增加农民消费提出政策建议。     

A true simulation study of three estimators at equal protection of respondents in randomized response sampling

In this study, three different estimators for estimating the proportion of a sensitive attribute in survey sampling are compared at equal protection of the respondents. The three estimators considered are due to Odumade and Singh (2009, Comm. Statist. Theory Methods) , Singh and Sedory (2011, Sociological Methods and Research) and a new estimator obtained by minimizing a chi‐squared distance. A SAS Macro is developed to compare these three estimators using a simulation study at equal protection of the respondents. A set of data from a real face‐to‐face interview was collected using two decks of cards and has been analyzed. The results are discussed.     

广东省流通服务业资本边际生产率变动趋势研究

为研究资本要素在广东省流通服务业中的使用和配置效率问题,首先运用永续盘存法估算出历年广东流通服务业中各行业以不变价计算的固定资本存量,再以收入法估算出历年行业的资本边际贡献份额,并计算了行业的不变价增加值,在此基础上估计出1993年~2003年10年间各行业的资本边际生产率。结果表明:这些行业的资本边际生产率在这10年间呈明显的上升趋势,即资本的使用效率在提高,但交通运输业的资本边际生产率偏低,且行业间的资本边际生产率差异增大,行业间资本的配置效率下降。     

中国与印度纺织品服装产业内贸易现状分析

中国和印度作为世界上最大的两个纺织品服装生产贸易大国,两国间的纺织品服装贸易分析逐渐引起了人们的关注。文章以2002—2011年两国纺织品服装贸易数据为例,用出口相似性指数、产业内贸易指数分析了两国纺织品服装产业内贸易的发展状况,并提出了两国在纺织品服装行业进一步发展的政策建议。     

On the Samuelson–Etula Master Function and the capital controversy

Abstract

The paper addresses the ambiguity that surrounds the conception of capital and its role in neoclassical price-and-distribution theory. The difficulties encountered in the various attempts to define the marginal product either of capital or of a capital good are recalled and the conclusion is drawn that neither concept appears theoretically sound. This historical reconstruction is combined with critical discussion of the recent attempt by Paul Samuelson to determine income distribution by means of the “Master Function”, a device previously developed and presented by Samuelson himself with Erkko Etula, and its “non-neoclassical” marginal products. Rather than the existence of a continuum of alternative technical possibilities, this construction assumes the simultaneous use of a discrete number of methods of production for the same commodity. Even though each technique employs the inputs in fixed proportions, the coexistence of various techniques permits the full employment of an arbitrarily given vector of input endowments. As is shown here, however, the coexistence of methods required for the differentiability of the Master Function can take place, if heterogenous capital goods are used in production, neither in the case with stationary relative prices nor in the non-stationary Arrow–Debreu framework.
