国债挤出效应的实证分析

发行国债投资于基础设施是带动经济增长的重要手段，但随着国债发行规模的不断扩大，国债对民间投资是否存在挤出作用成为了理论界关注的焦点。文章通过对投资主体投资份额、总量的相关分析以及国债投资方向的聚类分析，认为现阶段由于国债投资方向与宏观经济环境的原因，国债发行对民间投资挤出作用较小，带动作用较大。

On the decomposition of rank-dependent indicator of socio-economic inequalities in child malnutrition: Some empirical findings

The persistent socioeconomic disparities in child under-nutrition in developing countries raises an important health policy question - whether different nutrition base interventions are required for different areas? Addressing this question, the main objective of this study is to investigate the trends of socio-economic inequalities in child undernutrition in Pakistan and to assess the causes of these inequalities through decomposition analysis. Using Pakistan Demographic and Health Survey, round 2017–18, data this study examined inequalities in child undernutrition through different health inequality indices. Moreover, decomposition analysis is performed by applying generalized decomposition procedure under recentered influence function (RIF) regression to find the contribution of (i) differences in levels of different factors (composition effects) and (ii) differences in the intensity of association between socio-demographic factors and child undernutrition (coefficient effects) to the observed inequality. Study findings suggest substantial pro-educated inequalities in child under-nutrition. In addition, the decomposition analysis reveals the factors such as parental education and wealth status are significant contributors to the observed inequality. Moreover, different policy interventions, for rural and urban areas are suggested. There is the need to design public health, nutrition-based, interventions to overcome rural urban disparities through bridging gaps in educational endowments of rural and urban populations. Moreover, a balanced distribution of wealth might be helpful to reduce the rural-urban gap.     

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。     

中国区域经济发展差异及其原因的多尺度分析

本文采用经验模态方法对中国1953—2002年区域经济发展差异进行多尺度分析,并对不同尺度的区域经济差异的原因进行探讨。研究表明,50年来中国区域经济差异波动主要以60年尺度、17.5年尺度和趋势为主,近期区域差异呈扩大趋势。从不同尺度生产要素投入差异和区域差异的关系看,要素投入差异会引起区域差异,区域差异也会引起要素投入环境差异并引发要素投入差异的变化,在制定区域政策时应考虑区域差距波动的短期性和长期性。

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。
