货币政策的产业效应分析——基于中国货币政策的实证研究

本文从基于要素密集度不同的两部门例子出发，说明了由于行业自身的异质性，每个行业对同一货币政策冲击的反应各异。接着利用E—G两步法、ADL模型和基于VAR模型的脉冲响应函数分析1995年后中国六个行业对货币政策冲击的反应。结果显示第一、二产业、房地产业对利率政策冲击反应明显，第三产业、餐饮业和批发贸易零售业反应较小。在此基础上简单分析了造成行业反应不同的原因并给出相关的政策建议。     

Transfer sciences: management of distributed knowledge production

This paper is concerned to develop the notion of transfer science to take account of what is perceived to be the emergence of a new mode of knowledge production. The new mode which is characterised by the production of knowledge in the context of application, by transdisciplinarity, by homogeneity and organisational diversity, by enhanced social accountability and reflexivity, and by new forms of quality control. The thrust of the new mode of knowledge production is to call into question conventional notions of knowledge transfer and focuses instead on the organisational and managerial implications of the emergence of a socially distributed knowledge production system. The paper concludes with a brief discussion of the policy implications of the emergence of the new mode of production. Needed in the new mode are science and technology policies which promote institutional permeability and policies which enable governments, acting through their civil service to act as brokers in the new knowledge production process. Such brokerage is necessary to enhance permeability between institutions within a particular country but also to increase co-operation and collaboration between institutions across countries.     

开放经济条件下中国货币政策的内在矛盾

货币政策是由货币数量政策和货币价格政策组成的一个系统,对资源配置起重要作用的是一个国家的货币价格政策.而中国货币政策的内在矛盾则表现为汇率政策与货币数量政策和利率政策的矛盾,以及汇率政策与利率政策的不协调.     

Regulation and investment behaviour in the telecommunications sector: policies and patterns in US and Europe

This paper reports the results of the quantitative analysis of international experience of the relationship between infrastructure investment in the deployment of capacity that can carry large volumes of voice and data traffic and regulatory policy changes in the telecommunications sectors. It looks at the relationship between infrastructure investment for these infrastructure assets and the access pricing régimes for local exchange carriers in the United States and Europe. It then looks at the relationship between various aspects of regulatory and institutional policy changes in Europe and how they affect access prices.The paper finds that a lower access price promotes greater deployment of digital technology among US incumbent local exchange carriers (ILECs). Based on this finding, it suggests that it is in the ILECs interest to have access to their networks encouraged.The European data for interconnection are recent and far reaching conclusions are not feasible, but the findings, however, suggest that competition has worked by facilitating new entry through decreasing interconnection prices, although path dependencies, of existing and traditional concepts, in the mindsets of operators as well as regulators, may account for these findings.     

Pollution Externalities in a Model of Endogenous Fertility and Growth

An endogenous growth model with human capital formation, pollution caused by production of consumption goods, and endogenous fertility decisions made by altruistic agents with infinite horizons is presented. Consequences for optimal policy of modelling fertility as an explicit decision variable are examined. Because ordinary lump-sum transfers to individuals are no longer neutral, either revenue from a pollution tax must be redistributed to dynasties (working as an implicit tax on child births), or lump-sum transfers must be supplemented with an explicit fertility tax. Alternatively, the government can avoid distortions of the fertility decisions by maintaining an appropriate public debt. When abatement is highly productive, it can be optimal to subsidize fertility in order to increase total production.     

Capital, corporate income taxes, and catastrophe insurance

We provide estimates of the equity capital needed and the resulting tax costs incurred when supplying catastrophe insurance/reinsurance using a partial equilibrium model that incorporates a specific loss distribution for US catastrophe losses. After consideration of insurer investment in tax-exempt securities, tax loss carry-back/forward provisions, and personal taxes, our results imply that the tax costs of equity finance alone have a substantial effect on the cost of supplying catastrophe reinsurance. These results help explain a variety of industry developments that reduce tax costs. Also, when coupled with non-tax costs of capital, these results help explain the limited scope of catastrophe insurance/reinsurance.     

Money and exchange rates in the Grossman-Weiss-Rotemberg model

We analyze the impact of monetary policy on inflation, interest rates and exchange rates in a model with segmented asset markets developed by Grossman and Weiss (1983) and Rotemberg (1984, 1985). We find parameters for which real and nominal exchange rates in this model are (1) much more volatile than interest rates, inflation rates, and money growth rates, (2) highly correlated with each other, and (3) highly persistent. While this model fails to match the data in other important respects, it illustrates a potentially useful approach to modelling exchange rate behavior.     

货币政策效果非对称性及"阀值效应"分析

本文基于1992年1季度至2005年2季度数据，运用LM检验和t检验，研究我国货币政策的非对称性以及“阀值效应”，得出我国货币政策的“阀值”在-0．08-0．05之间。货币政策的非对称性和“阀值”的存在是由于微观信贷市场上的信贷配给导致的。“阀值”和“阀值效应”的存在反映了信贷配给的强弱程度，“阀值”可以用作度量信贷配给程度的指标，它间接地反映了信贷市场的完善程度。     

基于政策目标的存款利息得税的有效性分析

我国1999年开征的存款利息所得税是一次典型意义上的相机调控行为,短期内达到了预期的调控目标。但随着政策持续时间的延长,政策刚性对社会公平和经济长期增长的负面影响也在逐步增强。而且相机性财政政策仅仅是一项短期政策,不应该被长期实施。相机性政策的长期实施不仅会使短期的政策效应丧失,而且政策刚性产生的负面影响将会不断扩大。对利息所得税而言,如果不能将其纳入个人所得税改革的整体框架内统筹安排,则应考虑尽快退出。     

Monetary Policy and Financial Markets

Monetary policy and financial markets are intrinsically linked. Central banks conduct monetary policy by influencing financial market prices. Financial market prices reflect the expectations of market participants about future economic and monetary developments. Monetary policy works primarily through expectations. Transparency and credibility render monetary policy more effective. However, they are no substitutes for action. If a credible central bank uses words with the explicit aim of substituting them for action, it will risk losing credibility. To avoid what has been described as “the dog chasing its tail” problem, central banks must exercise caution in basing their monetary policy decisions on financial market information. The information about expected future developments reflected in market prices must be continuously cross-checked against economic and monetary indicators in what amounts to a “checks and balances” approach to monetary policy.
