国债转贷资金的宏观定位与微观管理

表面上看,中央对国债资金实行转贷似乎仅仅是国债投资资金运作方式的创新和改变,但是,只要对这一创新和改变作经济学理论和实践上的深入分析和思考,我们就会知道,国债资金实行转贷,不仅引起了政府信用主体的宏观定位和政府信用预算定位的改变,而且,还引起了政府信用资金的特质和效益概念的重大改变.     

Perpetual youth and endogenous labor supply: A problem and a possible solution

In the “perpetual youth” overlapping-generations model of Blanchard and Yaari, if leisure is a “normal” good then some agents will have negative labor supply. We suggest a solution to this problem by using a modified version of Greenwood, Hercowitz and Huffman’s utility function. The modification incorporates real money balances, so that the model may be used to analyze monetary as well as fiscal policy. In a Walrasian version of the economy, we show that increased government debt and increased government spending raise the interest rate and lower output, while an open-market operation to increase the money supply lowers the interest rate and raises output.     

Can the Risks of the Kyoto Mechanisms be Reduced Through Portfolio Diversification? Evidence from the Swedish AIJ Program

Through Joint Implementationand the Clean Development Mechanism, reductionsof greenhouse gas emissions achieved abroad canbe credited to domestic firms. However, thetechnical, economic and political risksinvolved may prevent the private sector frominvesting in such projects. This paperdescribes three types of risks which emissionreduction projects are exposed to. Eleven pilotprojects carried out under the ActivitiesImplemented Jointly (AIJ) program and financedby Sweden are evaluated. Actual project costsare found to exceed projected costs in allcases. Annual emission reductions also deviatefrom their expected values and vary stronglyover time, supporting the hypothesis that suchprojects are risky business. The riskmanagement tool portfolio diversification isapplied to a sample of Swedish AIJ projects.The results indicate that diversification canreduce the risks of greenhouse gas mitigationprojects significantly. Thus, carbon funds area promising way of lowering the risks of theKyoto Mechanisms for private sector investors.     

我国封闭式基金折价与基金运行绩效的相关性检验

笔者以我国的封闭式基金为样本,利用面板数据建模,综合考量了基金折价率与基金绩效指标间相关关系.研究结果发现,基金绩效指标对当期折价指标有显著的负的影响;而当期的基金折价指标不能准确预测未来绩效水平,即基金折价率并没有提供对未来基金绩效的有价值信息.     

农村政策性金融与财政支农关系

政策性金融的产生及其作用的发挥,实际上就是财政职能不断强化的一个产物,改革开放中后期以来,我国农村政策性金融体系的功能趋于弱化,其原因在于:财政实力被过多地削弱,公共产品资源配置不够合理,过分倚重商业性金融的支农效应而弱化了财政对农村政策性金融的支持。为此,应当健全财政对农村政策性金融持续投入机制与补偿机制,协调好财政政策与货币政策的关系,财政还应承担起对政策性金融业务监督管理的责任。     

积极财政政策执行效果及隐忧问题研究——H省执行情况个案分析

基于凯恩斯主义国民收入决定理论 ,通过对H省经济运行数据的实证模拟 ,分析H省积极财政政策的执行情况 ,并结合H省省情和我国国情 ,我们得到了九个基本命题 :命题 1∶H省经济处于投资陷阱之中 ,因而货币政策无效 ,财政政策充分有效。命题 2∶H省的财政政策乘数为 5 596,投资需求拉动乘数为 2 3 945,消费需求拉动乘数为2 2 0 1 5,财政支出回馈乘数为 0 2 2 66。命题 3∶H省国债转贷与补助资金拉动的经济增长率为 :1 988年 0 6个百分点 ,1 999年 0 9个百分点 ,2 0 0 0年 0 6个百分点 ,2 0 0 1年 0 5个百分点。命题 4:乘数愈大 ,积极财政政策的效果愈大 ,但积极财政政策退出造成的负作用也愈大 ,总需求和经济增长对积极财政政策的依赖程度也愈强。命题 5,民营化程度愈低 ,投资的利率弹性愈低 ,货币政策愈无效 ,反之亦然。命题 6,民营化程度愈低 ,财政依赖程度愈强 ,反之亦然。命题 7:我国的积极财政政策必然会退出 ;退出的最佳方式是淡出 ;维持现有国债规模是淡出的最可能的形式 ,是一个聚点均衡。命题 8:H省的民营化程度低于全国的平均水平 ,财政依赖程度高于全国的平均水平 ,自主性增长动力尤显不足。命题 9:如果没有激励民间投资的有效措施出台 ,积极财政政策淡出将使H省经济增长速度下滑。     

三种IP VPN技术实现方案的比较研究

VPN是企业内部网在因特网等会共网络上的延伸。通过一个私用的通道采建立一个安全的私有连接，将运程用户、公司分支机构、公司的业务伙伴等跟公司的内部网连接起来。构成一个扩展的公司企业网。通过虚拟专用网络既实现了传统专用网络所需的性能，同时相对于传统的专用网络又大大降低了网络的运营成本。对VPN技术的原理进行分析研究，可以充分发挥其优势，为企业的现代化管理与经营服务。     

Fiscal Policy in Europe: How Effective Are Automatic Stabilisers?

It is largely recognised that fiscal policy will have largerresponsibilities for cyclicalstabilisation in EMU given the loss of the monetary instrument.At the same time, theEMU's budgetary framework emphasises the need to rely onautomatic fiscal stabilisers,rather than active policies in cushioning the business cycle.We show that automaticstabilisers are relatively powerful in the event of shocksto private consumption, but lessso in the case of shocks to private investment and exports.In the case of supply sideshocks, the automatic stabilisers are largely ineffective,but this may actually be a goodthing to the extent that supply-side disturbances call forstructural adjustment rather thancyclical stabilisation.     

Growth,Employment and Taxation with Distortions in the Goods and Labour Market

Abstract. This paper analyses taxation in the presence of distortions in goods and labour markets in an endogenous growth model. The government disposes of capital, labour and consumption taxes. It is shown that the market solution leads to suboptimally low levels of growth and employment. However, available tax instruments are sufficient to attain the first‐best growth path in this economy. The paper further explores the relative distortion of capital and labour taxes. For plausible parametrisations of the model, lowering capital taxes dominate reductions in labour taxes in welfare terms.     

对冲基金的最新发展与监管框架重构研究

以近年来对冲基金的迅猛发展为背景，总结对冲基金竞争优势的来源，在分析现行国际监管制度缺欠的基础上，探讨以完善基金治理结构、强化信息披露和实施以风险为基础的监管措施三方面构筑有效合理的监管制度，具有重要现实意义。
