Liberalisation and de-regulation of the public sector in the transition from plan to market

The above analysis allows several conclusions to be drawn:

基于异构数据库的企业产品质量控制模型设计

企业产品质量控制是一项复杂的系统工程,来自不同生产单元的数据具有较强的异构性,不利于质量控制系统的整合。基于XML的数据集成方案为解决这一问题提供了可能。文章探讨了基于XML的质量控制模型的架构,为产品质量控制提供了一个较好的平台。     

Dominance Statistics: A Simulation Study on the d Statistic

Optimising a Probabilistic Model of the Development of Play in Soccer

We present a probabilistic model based on the one developed by Hernández Mendo and Anguera (Revista de Psicologíca Social, 16(1), 71–93, 2001). Here we have tried to break down the interaction contexts that the opposing teams are able to generate and transform during the game. We are aware that a given player or team does not produce consistent behaviour in similar situations. However, a degree of uncertainty is assumed to exist regarding whether the results obtained are a specific function of the analysis used. In order to carry out this research a category system which optimized that used in the previous model was developed. This system should enable the interaction between teams to be observed within the actual play of a soccer game. A lag sequential analysis was performed on the basis of a coding of the behavioural flow. After describing the behavioural patterns obtained a probabilistic model of the development of play in soccer is proposed.     

Environmental uncertainty, supply chain relationship quality and performance

Environmental uncertainty is a fact of life in today's supply chains. In this paper we develop a model of environmental uncertainty, supply chain (SC) relationship quality and SC performance. We use data from the electronics sector in Ireland to test our model. Our results provide mixed support for the model, with the moderating role of both demand and supply uncertainty being supported, but technological uncertainty not supported. We reflect on these findings and suggest a research agenda based on our results.     

从欧盟《电子垃圾处理法》的出台看国际贸易技术壁垒

世界贸易组织成立后，国际贸易中的保护措施发生了较大的变化。其中关于技术方面的贸易保护措施日益引起各国的高度重视。最近通过的欧盟《电子垃圾处理法》就是其中的一例。笔者在此主要讨论了该法的由来、对中国电子行业产生的影响及其带来的启示。     

建筑工程管理中全过程造价控制对策研究

随着社会经济和科学技术的发展,建筑工程如雨后春笋般涌现出来,规模也呈现出不断扩大的趋势.在对建筑工程进行管理的过程当中,工程造价是一个十分重要的因素,但是,要想在建筑工程当中对工程的造价进行良好的控制是十分不容易的,并且工程造价贯穿于施工的全过程.因此,要对工程造价进行全面良好的控制.     

Do stock market returns predict changes to output? Evidence from a nonlinear panel data model

Recent empirical work suggests a predictive relationship between stock returns and output growth. We employ quarterly data from a panel of 27 countries to test whether stock returns as useful in predicting growth. Unlike previous research, our approach allows for the possible non-linear effect of recessions on the growth-return relationship. There is strong evidence to suggest that a linear model would be misspecified and provide potentially misleading inference. Using a switching regression approach, we find evidence that returns are most useful in predicting growth when the economy is in recession.First version received: November 2002/Final version received: April 2003This paper benefited greatly from discussions with Kalvinder Shields, Mark Harris, Pete Summers, and Vance Martin.

Mixed Duopoly,Merger and Multiproduct Firms

The literature on mergers has extensively analyzed the decision to merge by private firms, but it has not considered the decision to merge by private and public firms. We assume that when a private firm and a public firm merge (or when one of them acquires the other), they set up a multiproduct firm in which the government owns an exogenous percentage stake. In this framework, we show that the decision to merge by firms depends on the degree to which goods are substitutes and on the percentage of the shares owned by the government in the multiproduct firm.
