公共物品供给效率研究

充足的公共物品供给在经济建设中有重大意义。文章分析了公共物品的性质及其供给模式,运用博弈论对公共物品的市场供给和政府供给效率进行了比较,认为我国应该构建多元的公共物品供给模式,推进服务型政府改革,明确政府和市场边界,减少公共物品供给中寻租行为。     

票据质押若干问题研究

票据质押是社会经济发展的产物,我国《票据法》《担保法》规范这种行为比较粗略,需进一步完善.作者认为,票据质押不是票据行为;票据质权可以有条件的适用善意取得制度;质押的票据可以进行承诺转质.     

国有企业混合所有制改革下股东利益博弈分析

国有企业混合所有制改革是当前理论探讨的热点。以分权控制理论为基础,构建国有股东、民营股东和监督机构三方的利益博弈模型,并对模型进行分析。结果显示,国有股东侵占民营股东的概率受监督机构监督成本和国有股东被监督损失等因素的影响,监督机构选择自主监督国有股东的概率受国有股东侵占行为惩罚力度系数、国有股东侵占额外收益和民营股东诉讼赔偿等因素影响。要加强对国有股东的惩罚力度,发挥好政府的监督作用,增强中小股东权利保障机制,推进国有企业混合所有制改革的步伐。     

壮族天琴源流探微——壮族天琴文化研究之二

通过对文献和田野调查资料的分析,初步认为:壮族天琴发源于广西龙州县金龙镇(古为金龙峒),源自当地原住民族壮族布傣族群在祭祀活动中使用的礼器或法器"叮鼎",其早期历史可以追溯到距今两千多年以前的战国至汉代的骆越人。宋至清代流传至凭祥、宁明、防城等地,中法战争后流传到与广西相邻的越南地区。     

Optimal block designs for double cross experiments

ABSTRACT

This paper presents systematic methods of construction of optimal block designs for a double cross experiments for both even and odd values of “p” parental lines. The both even and odd values of designs are derived by using initial block of unreduced balanced incomplete block designs and initial block of row–column designs given by Bose et al. (1953 Bose, R.C., Shrikhande, S.S., Bhattacharya, K.N. (1953). On the construction of group divisible incomplete block design. Ann. Math. Stat. 24:167–195.[Crossref] , [Google Scholar]) and Gupta and Choi (1998 Gupta, S., Choi, K.C. (1998). Optimal row-column designs for complete diallel crosses. Commun. Stat. Theory Methods 27(11):2827–2835.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), respectively. In this attempt we have found some new universally optimal block designs for double cross experiments.     

Testing a main effect in a three factor mixed model

In the present paper, the author has considered and compared the power of three test procedures, based on two preliminary tests of significance (PTS), for testing a main effect in a three factor factorial experiment. Davenport and Webster (1973) type test statistics are used in the final test. Recommendation for a suitable size of PTS has been made so that the power of a test procedure is adequately high.     

Type a incomplete multi-response designs

Srivastava considered the problem of designing and analysis of incomplete multi-response experiments, The main characteristics of the analysis given by her are investigated and a general class of incomplete multiresponse designs (Type A) is obtained on the basis of these investigations.     

A more generalized stirling distribution of the second kind

A more generalized stirling distribution of the second kind (MGSDSK) is introduced in this paper as the distribution of the sum of the independent but not identically distributed left truncated Poisson variables. Properties of MGSDSK are studied. The recursion relation and decomposition of MGSDSK are obtained. The rth moment is also found and a new recurrence relationship for them are given. A new incomplete exponential function is utilized in the derivations. A MVU estimate of the p, d, f. of MGSDSK is obtained.     

Generalized least squares estimation of multivariate nonlinear models with missing data

The method of estimated generalized least squares estimation of multiple response models is extended to the randomly missing date case. This estimation procedure is computationally simply when there are many missing data but the number of distinct patterns of missing data for the response vectors is small. The consistency and asymptotic normality of the proposed estimators are established.     

The Design of Scoring Schemes for Surveys Using the Block Total Response Method

ABSTRACT

In this article we investigate the design of scoring schemes for surveys using the block total response method. This method was first proposed by Raghavarao and Federer (1979 Raghavarao , D. , Federer , W. T. ( 1979 ). Block total response as an alternative to the randomized response method in surveys . J. Roy. Statist. Soc. 41 ( 1 ): 40 – 45 . [CSA] [CROSSREF]  [Google Scholar]) to provide accurate estimates of the base rates of sensitive characteristics using balanced incomplete block designs. The scoring scheme used in Raghavarao and Federer (1979 Raghavarao , D. , Federer , W. T. ( 1979 ). Block total response as an alternative to the randomized response method in surveys . J. Roy. Statist. Soc. 41 ( 1 ): 40 – 45 . [CSA] [CROSSREF]  [Google Scholar]) did not guarantee anonymity of answers and so the possibility of improving on this basic scoring scheme is considered in this article.
