Effet des Evolutions Techniques et des Changements de la Spécialisation Internationale sur les Marchés du Travail et les Systèmes Productifs: Comment les Statisticiens Pourraient-ils Relever les Défis?

Thinking about future needs and about what can reasonably be expected as feasible in the next century, how should producers of statistics direct their activity? Increasing complexity and diversity of needs leads us to recognize that, between producers and users of statistics, a mediating role is more and more often played by analysts and research workers who are requesting above all good data bases. Concerning infrastructures for statistics on productive systems, coordination between accountants and statisticians will be crucial, as well as adaptation of the constraints which, because of excessive worry about confidentiality, could prevent establishment or use of data bases. In an increasingly competitive world, where private firms will sell analyses and informations, particularly on very large enterprises, the public statistical service will remain essential in all respects. Intangible investments, innovations and many aspects of the internal organization of firms will create formidable challenges. Information on employment and labour markets has been much developed during the past decades; but on a few specific and difficult issues progress is still needed: lifecyles in the working-age population, acquisition of knowledge and skills in formal education and on the job, matching labour supplies and demands, and so on. Particular attention will have to be given to the lower levels of cultural and professional skills.     

Price Rigidity and the Selection of the Exchange Rate Regime

We evaluate and qualify Friedman's, 1953, “case for flexible exchange rates” in the presence of sticky prices in a two country model. We find that a flexible regime performs indeed better when the degree of nominal price rigidity is high while a bilateral peg does better when prices are fairly flexible. This result obtains independent of whether monetary policy is activistic or not and is mostly due to the negative relationship between employment and productivity shocks when prices are relatively sluggish (Gali, 1999). A unilateral peg tends to produce the lowest level of world welfare but it sometimes represents the best monetary arrangement for the pegger. JEL Classification Numbers: E32, E52, F33, F42

中小企业服务体系的动力因素:政府抑或中介组织

中小企业服务体系作为市场经济的产物,市场服务组织在服务提供过程中发挥着基础性的作用;政府和非营利性中介组织作为对市场服务供给失灵的补充,根据各自的职能优势,在服务提供中形成分工互补的关系。政府作为制度供给的主体,针对不同分布形态下市场条件与组织环境的差异,在中小企业服务体系的建设过程中分别发挥主导、引导和规制的作用。     

MUTUAL FUND PERFORMANCE EVALUATION – APPLICATION OF SYSTEM BCC MODEL

For the first time, this research adopts the system BCC model in data envelopment analysis in order to evaluate mutual fund performance and compares the results between the BCC model and the system BCC model. This study is based on the sample of stock funds and balanced funds in Taiwan, with the empirical results summarised as follows. (i) Under the system BCC model, the average score of balanced funds is greater than the average score of stock funds. (ii) There is a significant difference in efficiency scores between the BCC model and the system BCC model, and it is proper to adopt the system BCC model. (iii) The number of major reference sets that have been referenced under the BCC model is larger than under the system BCC model. (iv) If we neglect the distinctions between stock funds and balanced funds, there will be errors on performance assessment. Ultimately, the results reveal that there is a significant difference between the two models. Provided no consideration is made for the funds belonging to two different systems, errors in performance evaluation are inevitable. This research provides investors with both a more accurate and comprehensive evaluation method.

欧美国家的工作福利制度改革研究

20世纪末,很多发达国家都对原有的社会救助政策进行了改革,改革的共同趋势就是实行工作福利制度。该制度的推行在一定程度上减少了社会福利的依赖人数,扩大了就业。虽然还存在一些争议,但是工作福利制度已经受到了广泛关注,探讨欧美国家的工作福利制度改革对完善我国低保制度具有很强的借鉴意义。     

基于系统理论的水资源统一管理范畴探讨

水资源可持续发展战略已经成为各国社会、经济和环境发展的共同准则。我国也提出新时期治水思路是水资源的可持续利用,而这一目标的实现,在一定程度上取决于水资源的统一管理及其管理体制。文章运用系统理论,从水资源系统的整体性、层次性、目的性、动态性和开放性、自然属性和社会属性等特性出发,分析了水资源统一管理的必要性,提出基于系统理论的水资源统一管理的管理范畴模型,并结合深圳市和重庆市水务一体化改革的经验进行了实践分析。
