美联储前瞻性指引对新兴市场国家的溢出效应研究

基于前瞻性指引溢出效应的相关理论,选取17个代表性新兴市场国家为研究对象,运用面板向量自回归(PVAR)模型实证分析美联储前瞻性指引对新兴市场国家的溢出效应.结果表明:美联储前瞻性指引在短期内对新兴市场国家金融市场具有一定的冲击,在长期内对新兴市场国家经济增长存在滞后的正向作用.新兴市场国家应采取应对策略,做好风险识别和预警,加强预期管理,增强货币政策协调和合作,有效防范和化解外溢影响.     

科研开发与经济增长——兼论科研开发的溢出效应

经济划分为科研部门和非科研部门，科研开发对经济增长的作用及科研对非科研部门具有外溢效应。1999-2003年30个省市自治区的面板数据表明，科研开发对经济增长具有较大的拉动作用，同时科研开发部门对其他部门的外溢作用明显为正。

Cost Uncertainty and Unilateral Abatement

Unilateral abatement is sometimes advocated in order to set a good example that will make other countries follow. The aim of this paper is to investigate whether existence of correlated cost uncertainty provides an incentive for a country to undertake unilateral abatement. The theoretical model is driven by two main mechanisms; first, a learning effect, as the follower country might reduce its risk premium as it can observe the cost level in the leader country. Second, there is the public good effect, i.e., the marginal benefit of abatement declines when abatement is a public good and other countries contribute to pollution reductions. Results shows that unilateral abatement would be efficient in reducing uncertainty about the unit costs of abatement if a country with low cost uncertainty would undertake abatement first, while a country with initially high cost uncertainty would follow. However, countries may prefer to act simultaneously because of the larger uncertainties that are inherent in a sequential game.      

金融发展影响城乡收入差距的三大效应及检验

金融发展影响城乡收入差距主要通过三条途径,即金融发展的门槛效应、金融发展的降低贫困效应、金融发展的非均衡效应。本文利用中国和省级1978~2004年的相关数据进行实证检验,结果显示实证与理论假说相符。最后,提出了相关政策建议。     

汇率对产业内贸易的传导和冲击效应——基于中国东盟自由贸易区的分析

本文以中国与东盟六国18类产品的产业内贸易的月度面板数据作为分析基础，通过分析汇率与产业内贸易的传导关系、中国与东盟六国产业内贸易特点，并且建立产业内贸易指数与汇率的VAk模型．对我国的汇率对产业内贸易的冲击作用和动态关系做实证分析。研究发现：一是无论是短期或长期．汇率升值对绝大多数初级产品的产业内贸易是不利的，但在短期内它有助于提升大多数工业制品的产业内贸易水平．长期内对工业制品的产业内贸易冲击效应是分化的。二是汇率升值后长期内对不同劳动密集型产品的产业内贸易发展是一样的。三是无论是短期还是长期，初级产品的产业内贸易对汇率冲击的反应相当微弱．工业制品反应相对较强。

The flypaper effect and political strength

Simple models of local government behavior predict equal effects of private income and unconditional federal grants on local government expenditures. Numerous empirical analyses, however, find that the effect of grants is larger than the income effect. We argue that this flypaper effect may be a result of weak political leaderships in multi–issue and multi–party decision–making environments. In multi–issue institutions, a strong political leadership may reduce inefficiency due to interest group influence and inter–party bargaining in the local council. Utilizing data for Norwegian local governments in the 1930s, we find that political strength reduces the size of the flypaper effect. When the local council consists of only one political party, we cannot reject absence of a flypaper effect, while the flypaper effect is large in fragmented local councils.
