POVERTY IN RURAL INDIA: CASTE AND TRIBE

This paper analyzes the determinants of rural poverty in India, contrasting the situation of scheduled caste (SC) and scheduled tribe (ST) households with the non-scheduled population. The incidence of poverty in SC and ST households is much higher than among non-scheduled households. By combining regression estimates for the ratio of per capita expenditure to the poverty line and an Oaxaca-type decomposition analysis, we study how these differences in the incidence of poverty arise. We find that for SC households, differences in characteristics explain the gaps in poverty incidence more than differences in transformed regression coefficients. In contrast, for ST households, differences in the transformed regression coefficients play the more important role.     

经济学的性质与哲学视角审视下的经济学-一个基于经济思想史的理论回顾与展望

基于对经济思想史上一些相关文献的理论回顾,本文认为,在中国经济与中国经济学理论互动演变的当下格局中,是对经济学的性质、意义、任务以及它到底是一门什么样的学问这样一些元经济学问题进行理论反思和讨论的时候了。第二小节的文献追溯发现,在经济学说史上,伴随着由"政治经济学"向"经济学"的转变,经济学家们对经济学的本质和任务的理解也发生了很大变化。第三小节讨论了经济学能否成为一门价值中立的科学问题。研究发现,任何经济学派的理论观点都会潜含着某些价值判断和伦理原则在其中,经济学家作为一个"学术人"所面临的问题,首先是如何透过自己的文化信念和价值观,去发现人类社会中的某些"自然秩序"。第四小节讨论了经济学能否成为像物理学、化学等自然科学那样一种高度形式化的"精密科学"这一问题,并对目前主流经济学中流行的唯科学主义的研究偏向做了一些反思性的评论。本文最后所得出的结论是:为了中国的理论经济学在未来的健康成长,应该鼓励不同经济学流派和研究路径之间的竞争、对话和多元化发展。     

从二元财政到一元财政--国有资本财政向公共财政的转变

国有资本财政是我国目前财政体系的重要组成部分，因其作为财政范畴所包含的内在矛盾。必然处于动态变化过程中。随着国有企业改革的逐步深入，国有资本的公共属性将日益明显。国有资本财政最终将被公共财政所同化。

An invariance principle for progressively truncated likelihood ratio statistics

Summary In the context of time-sequential tests based on likelihood ratio statistics, weak convergence (in the Skorokhod as well as the sup-norm metric) of progressively truncated likelihood ratio statistics (to appropriate Wiener processes) is established through the construction of a continuous time-parameter martingale process. The case of local (contiguous) alternative hypotheses is also treated. The results are extended to the multiparameter case as well.Work partially supported by the Air Force Office of Scientific Research, U.S.A.F., A.F.S.C., Grant No. 74-2736 and partially by the National Heart, Lung and Blood Institute, Contract NIHNHLBI-71-2243 from the National Institutes of Health.     

高校教师激励的迟延效应及研究

激励是高校调动教师积极性和创造性的一个强有力的手段，进行激励应当适时，迟延激励会带来负的效应。本通过构建迟延激励的博弈模型和运用经济学中的边际分析方法，阐述了迟延激励的危害，揭示了高校激励的迟延效应产生的原因，并在此基础上，提出了高校教师激励迟延效应的防范措施。     

A further note on the asymptotic efficiency of friedman’s x r 2 -test

Summary For independently distributed error components, the asymptotic relative efficiency (A.R.E.) ofFriedman’sx _r ² -tests with respect to the classical analysis of variance test has been studied byElteren andNoether andSen [1967]. The present note extends these results to the case of correlated errors arising in some random-effects or mixed-effects models.

Goodness-of-fit test with nuisance regression and scale

In the linear model Y _i = x _i + e _i, i=1,,n, with unknown (, ), {\open R}^p, >0, and with i.i.d. errors e ₁,,e _n having a continuous distribution F, we test for the goodness-of-fit hypothesis H ₀:F(e)F ₀(e/), for a specified symmetric distribution F ₀, not necessarily normal. Even the finite sample null distribution of the proposed test criterion is independent of unknown (,), and the asymptotic null distribution is normal, as well as the distribution under local (contiguous) alternatives. The proposed tests are consistent against a general class of (nonparametric) alternatives, including the case of F having heavier (or lighter) tails than F ₀. A simulation study illustrates a good performance of the tests. Received July 2001     

刍议废弃物物流管理

废弃物物流的价值日益显现，其具有逆向性，不确定性和复杂性的特点。在废弃物物流管理中应遵循效益平衡原则，事前控制原则和系统化原则。最后，作者对废弃物物流管理提出了几点建议：政府监管与支持，建立“第三方”回收企业，业务外包和加强相关企业间的信息沟通。
