蒂布特模型启迪下的可流动公共产品供给

中国目前正处于城乡公共产品统筹供给的关键时期,研究符合中国国情的公共产品供给理论具有重要意义。蒂布特模型是关于公共产品供给机制的理论研究,其政策含义是政府要采取促进居民流动的方式来提高公共产品的配置效率。由于该模型所作假设的现实性较弱,其结论和应用有一定局限性。根据流动程度,可以把公共产品划分为可流动公共产品和不可流动公共产品两类,可以通过可流动公共产品的流动来提高公共产品的配置效率。中国目前在城乡可流动公共产品优化配置方面有较大发展空间。     

On Rao score and PearsonX 2 statistics in generalized linear models

The identity of the Rao score and PearsonX ² statistics is well known in the areas where the latter was first introduced: goodness-of-fit in contingency tables and binary responses. We show in this paper that the same identity holds when the two statistics are used for testing goodness-of-fit of Generalized Linear Models. We also highlight the connections that exist between the two statistics when they are used for the comparison of nested models. Finally, we discuss some merits of these unifying results.

世界贸易组织争端解决机制评析

从世界贸易组织（WTO）成立后的实践来看，它的争端解决机制为各成员方解决贸易争端、为帮助世界贸易秩序的稳定和发展发挥了重要作用。但是从对WTO争端解决机制的几个方面的具体的分析、评价中可以得知它也并非尽善尽美，还有待进一步的发展和完善。     

浅探杠杆收购战略在我国运用的可行性

企业购并是国外特别是美国企业成长和发展的一个重要手段。在一百多年的企业发展历史上,在完全市场经济的条件下,美国企业、金融界进行了大量的创新,开发了丰富的金融工具。其中杠杆收购战略就是创新工具的一个典型例子。尽管我国开始市场经济的时间较短,但是金融界和政府部门一直在改革和创新具有中国特色的金融市场。探讨杠杆收购战略在我国运用的可行性,可以为我国的企业购并注入新的活力。

Missing data and forecasting in multivariate time series: An application of the common components dynamic linear model

Summary The paper deals with missing data and forecasting problems in multivariate time series making use of the Common Components Dynamic Linear Model (DLMCC), presented in Quintana (1985), and West and Harrison (1989). Some results are presented and discussed: exploiting the correlation between series, estimated by the DLMCC, the paper shows as it is possible to update state vector posterior distributions for the unobserved series. This is realized on the base of the updating of the observed series state vectors, for which the usual Kalman filter equations can be applied. An application concerning some Italian private consumption series provides an example of the model capabilities.

AN ALGORITHM FOR THE CONSTRUCTION OF OPTIMAL OR NEAR-OPTIMAL CHANGE-OVER DESIGNS

This paper presents an algorithm for the construction of optimal or near optimal change-over designs for arbitrary numbers of treatments, periods and units. Previous research on optimality has been either theoretical or has resulted in limited tabulations of small optimal designs. The algorithm consists of a number of steps:first find an optimal direct treatment effects design, ignoring residual effects, and then optimise this class of designs with respect to residual effects. Poor designs are avoided by judicious application of the (M, S)-optimality criterion, and modifications of it, to appropriate matrices. The performance of the algorithm is illustrated by examples.
