Crowding-out effect of the current food stamp subsidy scheme

We construct a model to illustrate that the current food stamp subsidy scheme fails to achieve its stated aim due to the crowding-out effect. More specifically, if the household income is sufficiently low, only a corner solution exists, and a full subsidy is needed.     

Output gap measurement and the New Keynesian Phillips curve for China

The New Keynesian Phillips curve implies that the output gap, the deviation of the actual output from its natural level due to nominal rigidities, drives the dynamics of inflation relative to expected inflation and lagged inflation. This paper exploits the empirical success of the New Keynesian Phillips curve in explaining China's inflation dynamics with a new measure of the output gap. We estimate the output gap using the Bayesian multivariate Beveridge–Nelson decomposition method, based on a multivariate dynamic model featuring distinct interactions among inflation, money, and real output in China. The empirical results using quarterly data spanning 1979–2010 show that the new measure of the output gap outperforms the traditional measures in fitting the New Keynesian Phillips curve. This result provides useful insights for inflation dynamics and monetary policy analysis in China.     

通货膨胀率周期波动与非线性动态调整

本文运用MRSTAR模型研究我国通货膨胀率的周期阶段划分、通胀率周期波动的非线性和非对称性动态特征,通胀率不同阶段相互转移的路径及其内在机理。实证研究表明,我国通货膨胀率波动可以划分为通货紧缩、通缩恢复、温和通胀以及严重通胀四个阶段,通胀率波动不同阶段的划分不仅依赖于通胀率的水平,也依赖于通胀率的增加量;在一个波动周期内,通胀率不同阶段的典型转移路径为:通货紧缩→温和通胀→严重通胀→温和通胀→通货紧缩;我国通货紧缩与温和通胀持续时间较长,而严重通胀持续时间很短;冲击对通胀率系统不具有持久性影响,正向冲击与负向冲击的影响具有非对称特征。     

“省直管县”改革会损害地级市的利益吗?

我国多个地区正在探索"省直管县"体制改革,目前的最大顾虑是改革是否会损害地级市的利益?本文利用1999—2008年我国地级市数据,通过系统GMM估计对此进行了实证研究。结果发现:"强县扩权"提高了城市财政收入,抑制了城市财政支出增长;财政"省直管县"的作用则恰好相反。"强县扩权"促进了城市经济增长,但不利于城市第三产业的发展;财政"省直管县"虽然降低了城市经济增长速度,却提高了第三产业比重。两项改革措施都抑制了城市规模的扩大,但有利于改善城市的环境质量。因此,我们不能笼统地断定"省直管县"改革一定会有损地级市的利益、阻碍城市化的进程,应深入地研究各项改革措施的利弊得失,做到综合运用、扬长避短。     

Income distribution, efficiency and rationing

This paper studies the impacts of income distribution on the efficiency of trade mechanism and rationing of agents who are priced out of trade in a dynamic search model with two-sided asymmetric information. Buyers and sellers have asymmetric information about valuations and incomes respectively. In such a frictional environment, the effects of several variants of changes in income distribution on efficiency of trading mechanism and the population of rationed buyers and sellers are elaborated.     

Why should Austrian economists be pluralists?

Peter Boettke (2007) argues that economists need not act pluralistically in order for pluralism to thrive in the marketplace of economic ideas. From a market process perspective, Boettke sees intellectual diversity and openness as catallactic outputs, not inputs—emergent by-products of academic specialization and trade. To expect individual scholars to behave in a pluralistic manner is unnecessary and “completely inappropriate” since it detracts from their central task: “to commit themselves to an approach and pursue it doggedly, even in the face of great doubt and resistance by one’s peers” (Boettke 2007). This paper proposes a Smithian revision of Boettke’s position. The author argues that scholarly pluralism is best understood as a constitutional rule of academic life—a virtue ethic that promotes learning and intellectual freedom by mitigating tyranny and autarky in the republic of science. Drawing from the writings of Adam Smith, Friedrich Hayek, Deirdre McCloskey, Bruce Caldwell, James Buchanan, Don Lavoie, and Boettke himself, the author argues that scholarly pluralism has been, and continues to be, a necessary condition for the flourishing of Austrian economists as free, responsible, efficacious thinkers.     

中国城市政府公共支出效率分析——基于四阶段DEA方法的实证研究

本文以2008年中国内地126个地级以上城市为样本数据,利用四阶段DEA方法,对中国城市公共支出效率进行了实证分析。结果显示:如果不对外部环境因素加以控制,则经典的DEA方法将会高估城市公共支出效率;在控制外部环境因素影响后,样本城市公共支出效率得分为0.353,表明在保持支出不变下,通过改善组织管理、优化支出规模及结构,公共服务供给水平可提高约64%,城市公共支出效率还有很大的提升空间;经济发达、较大的辖区面积是城市公共支出效率提升的有利条件,而人口增加对公共品供给产生的拥挤效应不利于城市公共支出效率提升。     

分析师的盈利预测偏差与本地优势

分析师在金融市场中起着重要的信息中介作用,其信息来源及获取方式会直接影响信息处理的质量。本文从分析师对企业年度盈利预测的偏差出发,基于对分析师与公司地域关系的实证研究,发现分析师在预测那些所在地与分析师隶属的机构同属一个省份的公司时,预测结果更加准确,这种本地优势与公司高成长性及公司国有性质显著相关。研究还发现,我国分析师的本地优势与个人本身的乐观性并无关系,可能更多与信息优势相关。     

我国商业银行信用评估的行为决策框架与锚定效应分析

根据前景理论,通过对信贷经理人的调查,对信用评价的决策框架和信用评价中的锚定效应特征进行了实证分析.调查表明,信贷决策并不完全决定于信用评估结果,最优信用评价决策与现实不一致;在信用评估中,信贷经理人能力比信用评估体系更为重要,信贷经理人的经验、专业能力和价值观对信用评估都将产生影响;信用评估中存在锚定效应,对借款人信用评价产生重要影响.     

企业年金基金管理费模型的优化选择

在分析现有模型基础上研究并设计适合企业年金的管理费优化模型,该模型更加注重基金资产的安全性,解决了目前企业年金基金管理中的风险不对等问题,基金管理人将更加注重企业年金追求本金安全及长期稳健增值的目标,使企业年金资产的安全性得到较大保障,该模型亦可推广到所有追求长期安全增值以绝对收益为目标的基金使用。
