基于金融安全的资本流动:理论解读与中国实证 总被引:2,自引:0,他引:2
Li Cheng Hao Junxiang 《国际金融研究》2006,(8)
基于IS-LM-BP模型阐述了资本流动—经济非均衡的生成机制,揭示了资本流入规模、资本流入结构、外汇储备及经常项目是影响一国资本流动金融安全的主要因素。通过建立资本流动影响金融安全的测算体系,对1996~2005年我国资本流动进行了实证分析,结果表明:(1)中国资本流动状况总体较好,状态界定为安全;(2)资本流入规模正常,但期限结构不够合理;(3)现阶段我国资本流动的安全运行有保障。 相似文献

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor productivity are more profitable. We incorporate this channel in a new dynamic general equilibrium model with endogenous economic growth and heterogeneous overlapping generations. We calibrate the model for the US economy and obtain the following results. First, the effect of a decline in population growth on labor productivity growth is positive and quantitatively significant. In our benchmark, it is predicted to increase from an average annual growth rate of 1.74% over 1990–2000 to 2.41% in 2100. Second, institutional characteristics of the pension system matter both for the growth performance and for individual welfare. Third, the assessment of pension reform proposals may depend on whether economic growth is endogenous or exogenous. 相似文献

This paper studies pension fund design in the context of investment in the debt and equity of a firm. We employ a general equilibrium framework to demonstrate that: (i) the asset location ‘puzzle’ is purely a partial equilibrium phenomenon, conceived in a risk neutral setting, that disappears with the introduction of sufficient risk aversion; (ii) the inability of policy makers to manage an economy with multiple firms yields a mixed equilibrium, where bonds are observed in both taxable and tax-deferred accounts; and (iii) the Pareto-efficient pension plan comprises of a defined benefit plan. 相似文献

The internal rate of return (IRR) is generally considered inferior to the net present value (NPV) as a tool for evaluating and ranking projects, despite its inherently useful comparability to the cost of capital and the return of other investment opportunities. We introduce the “selective IRR”, a return criterion which, as a selection of an extended set of possible IRRs, is NPV-consistent. The selective IRR always exists, is unique, easy to compute, and does not suffer from drawbacks that befall the project investment rate, the only other known NPV-consistent return criterion. 相似文献

One of the main issues with the concept of ecosystem services is its absence on the ground in concrete operational decision-making contexts; that is, an implementation gap. In this study, we investigated if this gap could be overcome through the use of open-source data and free tools, and the adoption of a short-term participatory process. We tested these methods in the context of a project in the urban metropolitan area of Bordeaux (Communauté urbaine de Bordeaux: CUB) in France. The ecosystem services were defined using a participatory approach involving local stakeholders, and then selected scenarios were simulated to test the impact of various development or conservation plans. The study addressed three main questions: (1) Is it possible to adopt a simple methodological approach that overcomes the implementation gap through the development of a user-friendly and inclusive method? (2) What is the added value of a participatory approach? (3) With regards to four scenarios in this territory, what are the ES trends in the selected biophysical and monetary indicators, and will knowledge of these trends help planners to shape a sustainable trajectory for the territory? 相似文献

A previous study finds that in a market where a manufacturer faces uncertain demand and sells to consumers through competitive retailers, the manufacture wishes to support adequate retail inventories by imposing resale price maintenance (RPM). I show that if retail inventories are allocated to consumers through first‐come‐first‐served rule rather than efficient rationing rule in the game with unconstrained retail competition, imposing RPM may not be profitable. It may not encourage more retail inventories either. RPM may also lower consumer surpluses and social welfare. This study casts some doubt on the demand uncertainty theory that supports RPM. 相似文献

The amount of customisation to an enterprise resource planning (ERP) system has always been a major concern in the context of the implementation. This article focuses on the phase of maintenance and presents an empirical study about the relationship between the amount of customising and the resulting support effort. We establish a structural equation modelling model that explains support effort using customisation effort, organisational characteristics and scope of implementation. The findings using data from an ERP provider show that there is a statistically significant effect: with an increasing amount of customisation, the quantity of telephone calls to support increases, as well as the duration of each call. 相似文献

从资金需求方出发,以2009年10月至2016年12月深圳创业板和中小板首次公开上市的公司为样本,实证检验了政治关联对风险投资引入方式的影响,以及激励机制和监督机制这两种公司治理机制的调节作用,得到结论如下:政治关联企业倾向于在发展后期引入风险投资;政治关联企业倾向于选择国有性质、经验丰富以及参与程度高的风险投资机构;激励机制会加强政治关联企业在发展后期引入风险投资以及选择国有性质、经验丰富、参与程度高的风险投资机构的意愿;监督机制会减弱政治关联企业在发展后期阶段引入风险投资以及选择国有性质、经验丰富、参与程度高的风险投资机构的意愿。结论对拓展政治关联与风险投资领域的理论和实践具有重要启示意义。 相似文献

技术转化为资本,资本创造价值已经成为共识,技术资本在不同公司创造价值的作用程度不同,根源是技术资本配置效率问题。选取沪深两市2008-2013年间制造业上市公司为样本,检验了基于不同股权性质的公司环境不确定性对企业技术资本配置效率和价值的影响,研究结果表明:①企业环境不确定性程度越高,技术资本配置效率越低,并且技术资本配置偏离度在国有公司中表现为配置过度,在非国有公司表现为配置不足;②在股权性质为国有的公司中,由环境不确定性引发的技术资本配置偏离将降低企业价值,在非国有控股公司中,由环境不确定性导致的技术资本配置偏离将增加企业价值。 相似文献
