Tinbergen in De Economist

Jan Tinbergen's scientific writings cover six main areas of research. His articles in De Economist represent these areas; in some cases the contributions to De Economist were of a pioneering nature (business cycles, economic models, economic integration); in others De Economist was the first or even single outlet for Tinbergen's work. This article provides an overview of these contributions. The wide scope of Tinbergen's areas of research goes together with a unity in approach, the characteristics of which are: policy relevance, quantification and measurement, balance in analysis and presentation, and learning from experience. Tinbergen's articles in De Economist bear witness to this approach which at the time also met with scepticism and resistance as this overview shows. According to Houthakker, Tinbergen's main contribution may be that, amidst the pleas of interest groups and the slogans of the laity, an attempt is made that the voice of the professional economic researcher be heard. Tinbergen's work still sets an agenda for both economic research and policy making.     

超市进货交易关系法律调整的若干问题探讨——论“零供”关系法律调整

近年来，我国零售商供应商矛盾突出，引起了各方关注。商务部等五部委发布的《零售商供应商公平交易管理办法》，是近年来专门调整零供关系的政府部门规章，在稳定流通秩序方面发挥了一定的作用，但对此也有一些不同观点。为完善零供（买卖）关系的法律规范体系，推进和谐商业环境及商事法治建设，本文对调整零供关系的法律属性，少数零售企业恶意占压、骗取供应商贷款的综合治理，风险预誓机制等相关问题提出了自己的一些见解。     

国有企业融资次序的政治经济学分析

与经典资本结构理论的结论不同，我国国有企业的融资次序恰好是倒序的。这一现象有着深刻的政治经济学内涵，本质上它是由国家追求义理性的最大化，缓解财政压力的行为所内生决定的。因此，单纯从西方主流理论出发，不考虑我国转轨经济的背景对国有企业融资行为和由此而引致的治理结构所进行的分析，是不得要领的。     

重心定理在进度控制中的运用

公共秩序保留制度的式微

公共秩序保留作为国际私法的一种特殊制度,其实质是用来保护本国的国家利益,从而拒绝外国法的适用或者拒绝承认与执行外国法院判决或外国仲裁裁决,因而被称为保护本国利益的“安全阀”。虽然各国对该制度理解不一,但都在立法上对它进行了规定。晚近,各国国际私法对公共秩序保留的态度出现了不同程度的改变,公共秩序保留开始出现式微的发展趋势。这种趋势的出现,除了其本身的缺陷外,主要是全球化的影响以及法律趋同化的演变。     

民主政治与社会和谐

社会和谐问题的关键,是搞好以民主法治为中心的国家治理。中国的制度变迁是经济和社会层面的变迁,是自上而下推动的改革型的变迁,在由权力集中到权力分散的制度转型过程中,稳中求进是中国实现社会和谐的经验总结,制度的设计不宜过于完美。民主政治是社会和谐的前提和归宿,是执政合法性的来源,没有民主政治就没有和谐社会。

A Note on Minimax Mixture of Distributions Free Procedure for Inventory Model with Variable Lead Time

In recent papers, Moon and Choi (1998) and Hariga and Ben-Daya (1999)considered a continuous review inventory model with a mixture of backordersand lost sales in which the lead time, the order quantity, and the reorder pointare decision variables was studied. Moreover, they also develop a minimaxdistribution free procedure for the problem. While the demands of differentcustomers are not identical in the lead time, then we can't only use a singledistribution (such as Moon & Choi (1998) and Hariga & Ben-Daya (1999))to describe the demand of the lead time. Hence, we correct and extend the modelof Moon and Choi (1998) and Hariga and Ben-Daya (1999) by considering thelead time demand with the mixture of distributions. In addition, we also applythe minimax mixture of distributions free approach to the model by simultaneouslyoptimizing the order quantity, the reorder point, and the lead time to devise a practical procedure which can be used without specific information on demand distribution.
