Privatization Policies and Public Enterprise: A Survey*

This paper surveys and analyzes the economic literature on ‘privatization’ policies, restricting coverage to policies designed to improve the operating efficiency of public sector enterprises through increased exposure to competitive market forces. These include asset sales, liberalization (or deregulation) and franchising. The objectives, incentives and constraints of public and private enterprises are examined, and evidence on their comparative performance is analyzed. Public sector revenue effects from asset sale are also explored. On the basis of these considerations, the paper concludes that liberalization is an important ingredient in any policy package designed to improve the operating efficiency of public sector enterprises. Asset sale may enhance the beneficial impact of deregulation but asset sale in the absence of deregulation is unlikely to improve efficiency, and may introduce additional market distortions. Franchising is seen as an appropriate mechanism for privatization when the market is inherently monopolistic and when the government desires to retain control over output and/or price.     

加权Hardy空间上算子序列的收敛性

设D为复平面C中的开单位圆盘，φ：D→D解析，ψ：D→C，Cψ，φ是H^2（β）上的加权复合算子，S是加权移位算子，该文通过讨论算子序列{S^＊nCψ，φS^n}n=1^∞与{S^＊nCψ，φ^＊S^n}n=1^∞的收敛性来研究H^2（β）上加权复合算子Cψ，φ的渐近Toeplitz性．

Tax Law Improvement in Australia and the UK: The Need for a Strategy for Simplification

In both Australia and the UK, programmes are under way to simplify tax legislation by rewriting it. This paper demonstrates that tax simplification is a complicated concept and concludes that sustainable improvement is unlikely to be achieved if reform is limited only to linguistic changes. Tax law is complicated because there are powerful pressures that tend to increase the complexity of modern tax systems and these should also be considered in any simplification programme. In addition, tax simplification may be promoted by the greater use of purposive legislation — that is, legislation drafted in terms of general principles rather than much more comprehensive legislation designed to deal with every likely possibility. The paper examines the progress of the Australian Tax Law Improvement Project and argues that what is needed is a strategy for tax simplification that is incorporated into the process of generating tax policy itself.

我国农村金融供需非均衡性问题及对策研究

我国是一个有着13亿多人口的大国家,其中农村人口就达8亿多以上,农业是工业和服务业等的基石。金融作为社会经济的核心在社会主义经济发展过程中发挥着重要作用,建设中国特色社会主义和谐社会,重点和难点都在"三农"问题上,"三农"问题一直是党和国家非常关心的问题。农村金融的稳定发展直接关系着我国农业生产的持久增长,农民收入的有效增加和农村经济社会的繁荣稳定。农村金融体制仍存在很多需要解决的问题,尤其是农村金融的供需存在很大的非均衡性。本文从理论角度出发,分析了当前我国农村金融供需的现状以及所存在的问题原因,并从我国国情出发,结合实际情况,对农村金融的供需实现高水平均衡的构建提出了一些可行性的政策建议。
