社会审计委托代理分析

本文分析了社会审计契约中委托代理关系及审计信息不对称表现及形成原因,通过建立社会审计的委托代理模型,揭示了在审计人和委托人均完全理性的假设下,委托人可以通过激励机制鼓励审计人尽最大努力完成工作。在此基础上分析了我国社会审计收费制度的不合理性、转轨经济环境下社会审计合约具有的不完全契约特性,并提出了改革的设想。     

住房政策的局限性:政策的初衷与实施效果的背离

在房价上涨过快的背景下,基于舆论的压力,政府常常会出台一些旨在稳定房价、解决住房短缺问题的政策,然而有些政策的实施效果却常常背离政策的初衷.回顾了美国40年代实施的房租管制,并分析了中国正在实施的提高税收和经济适用房政策,发现这些政策的实施效果大都适得其反,不仅没有达到预期的目标,反而使得住房问题恶化.     

Macroeconomic forecasting using structural factor analysis

The use of a small number of underlying factors to summarize the information from a much larger set of information variables is one of the new frontiers in forecasting. In prior work, the estimated factors have not usually had a structural interpretation and the factors have not been chosen on a theoretical basis. In this paper we propose several variants of a general structural factor forecasting model, and use these to forecast certain key macroeconomic variables. We make the choice of factors more structurally meaningful by estimating factors from subsets of information variables, where these variables can be assigned to subsets on the basis of economic theory. We compare the forecasting performance of the structural factor forecasting model with that of a univariate AR model, a standard VAR model, and some non-structural factor forecasting models. The results suggest that our structural factor forecasting model performs significantly better in forecasting real activity variables, especially at short horizons.

Component efficient solutions in line-graph games with applications

Recently, applications of cooperative game theory to economic allocation problems have gained popularity. We investigate a class of cooperative games that generalizes some economic applications with a similar structure. These are the so-called line-graph games being cooperative TU-games in which the players are linearly ordered. Examples of situations that can be modeled like this are sequencing situations and water distribution problems. We define four properties with respect to deleting edges that each selects a unique component efficient solution on the class of line-graph games. We interpret these solutions and properties in terms of dividend distributions, and apply them to economic situations. This research has been done while the third author was visiting Tinbergen Institute at the Free University, Amsterdam. The research is part of the Research Programme “Strategic and Cooperative Decision Making” at the Department of Econometrics. Financial support from the Netherlands Organization for Scientific Research (NWO) in the framework of the Russian-Dutch programme for scientific cooperation, is gratefully acknowledged. The third author also appreciates partial financial support from the Russian Leading Scientific Schools Fund (grant 80.2003.6) and Russian Humanitarian Scientific Fund (grant 02-02-00189a).

Idea and goals of environmental protection and ecological construction in the 11^th five-year plan period

In this paper, the executive of the 10th Five- Year Plan in the field of environmental protection and ecological constrution is reviewed, and the charactristics of economic growth and its environmental impact on the 11^th Five-Year Plan is forecasted and analyzed. A principal idea of eavironmental protection and ecological construction is put forward for the 11^th Five-Year Plan pertod： strensgthen the point treatment in key areas and set the main targets based on the idea. The relating countermeasures in national level are proposed as follows： set up appropriate ideas for official achievements by launching resources and environmental cost acconting; adjust the industrial struacture actively by industrial policies and strenuous work; develop circular economy, change the mode of environmental protecgon from end treatment to headstream and proeess control： strengthen the market mechanism in the process of pollution treatment, set up the system of ＂who treats who benefits＂ ; perfect interrelated laws and standards, strengthen the ability of environmental munagement; lay extra emphasis on two key targets： water pollution tretment in key river basins and management of the reserves; and combine the ecological consnuction and poverty alleviation in higher level.     

基于主成分分析法的人类发展指数替代技术

在本文中,我们采用基于协方差的主成分分析法来分析1990年以来UNDP发布的中国人类发展数据,然后采用Spearman秩相关系数来分析获得的主成分与HDI之间的关系。研究表明,主成分分析法不仅能够有效地替代传统的人类发展指数编制方法,其形成的动态权重结构还可以有效地透视人类发展差距模式的历史演进过程,以及人类发展的各个方面(如预期寿命、知识教育和体面的生活等)在整体发展进程中的角色变化。对中国人类发展数据的分析结果也表明,尽管1990年以来中国各地区在经济、教育和健康方面均取得了重大进步,但三项发展之间存在着严重的不协调,地区发展差距也越来越多地体现为经济发展差距,这些反映了改革开放以来中国各级政府过分强调经济增长而带来的片面、不协调的人类发展。实现经济社会的协调发展,是时代的要求,也是当前我国各级政府面临的主要任务。而强调公共服务职能、推动地方政府的服务型转型,是消除不平衡发展的关键。     

截瘫病人的护理

总结了截瘫病人的护理经验，早期关键是预防并发症的发生，后期要重视功能锻炼和心理护理。护理重点是：呼吸道护理、中枢性高热的护理、压疮的预防和护理、泌尿系统感染的预防和护理，便秘的护理、功能锻炼及心理护理。帮助患者安全渡过危险期，顺利向功能恢复和重建过度，提高生存质量。     

中国农村金融体系的资金配置功能分析

按照金融功能观,资金配置是金融体系最重要的功能.中国农村金融体系未能有效地发挥资金配置功能,是因为过去的农村金融改革主要遵循金融机构观.金融机构观使得农村金融体系不能适应外部环境,从而也就不能满足农村经济发展的需要.     

Do labor market institutions matter for business cycles?

Using panel data of 19 OECD countries observed over 40 years and data on specific labor market reform episodes we conclude that labor market institutions matter for business cycle fluctuations. Spearman partial rank correlations reveal that more flexible institutions are associated with lower business cycle volatility. Turning to the analysis of reform episodes, wage bargaining reforms increase the correlation of the real wage with labor productivity and the volatility of unemployment. Employment protection reforms increase the volatility of employment and decrease the correlation of the real wage with labor productivity. Reforms reducing replacement rates make labor productivity more procyclical.
