Business cycle asymmetry via occasionally binding international borrowing constraints

This paper illustrates how occasionally binding credit constraints can be quantitatively important to delivering business-cycle asymmetries. An empirical exercise suggests that countries display some business-cycles asymmetries, and an open-economy real business-cycle model is assessed where an international borrowing constraint binds occasionally. In the model, downward movements with a slack constraint are sharper and quicker than upward movements with a binding constraint, and this can deliver asymmetry over the business cycle. The model is calibrated to Canadian data and suggests that a necessary ingredient for asymmetry is a high initial level of foreign debt.     

Testing for structural breaks in panel varying coefficient models: with an application to OECD health expenditure

In this article, we propose a model selection approach for testing structural breaks in a semiparametric panel varying coefficient model. Monte Carlo evidence shows that the proposed model selection approach performs well in finite sample settings. Applying the method to an empirical data, we find evidence of structural breaks in Organisation for Economic Co-operation and Development (OECD) health expenditure data by allowing for income elasticity to be state (income)-dependent. The relationship between health expenditure and income is subject to two types of structural changes: smooth changes over income and structural breaks in the time dimension. The findings hold for both foreign exchange rate-converted and Purchasing Power Parity-converted expenditure and GDP.     

公允价值与股市过度反应——来自中国证券市场的经验证据

本文以我国2007年至2010年16个季度公告日为样本,以公允价值变动损益和股票回报为观察对象,对公允价值与股市过度反应进行了实证研究。研究发现:(1)股市过度反应与公允价值变动损益显著相关;(2)过度反应主要存在于估计窗口而非事件窗口;(3)我国金融业上市公司的金融资产市值计量模式显著放大了股市泡沫,且在不同的市场条件下,股票回报对公允价值的过度反应程度呈现出非对称性。本文扩展了事件研究法,给出了公允价值引起股市过度反应的具体标准,重点检验了估计窗口的信息含量,使之更加适应于公允价值资产市值计量模式的研究。本文验证了公允价值作为"会计加速器"作用的存在,有助于理解公允价值计量模式对我国金融稳定的影响机理。     

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。     

区域矿产资源开发模式、生态足迹效率及其驱动因素——对“资源诅咒”学说的另一种解读

文章考察在生态足迹约束条件下的经济增长与资源禀赋的变动关系,分析了我国矿产资源丰裕区形成"资源诅咒"现象的重要因素。通过实证分析发现我国矿产资源丰裕区矿产资源开发模式具有一定的有条件的技术进步推动型特征,但是却忽略了技术效率水平的提高;城市化水平对生态足迹效率有着显著的负向影响,而工业化水平和外商直接投资水平则有着显著的正向影响。     

中国贸易开放度、贸易结构与通货膨胀不确定性关系

完全预期到的通货膨胀在理论上并不会对真实经济活动产生实质性的影响,通货膨胀的真正危害在于它的不确定性。随着贸易开放的不断扩大和深化,影响中国通货膨胀的不确定性的因素变得更加复杂。本文利用EGARCH模型估计了中国的通货膨胀不确定性,并在此基础上利用协整分析方法检验了贸易开放度、贸易结构与通货膨胀不确定性的关系。研究表明:贸易开放度的提高对通货膨胀不确定性具有负向的影响;贸易结构的变化对通货膨胀不确定性具有正向的影响。     

市场潜力、经济集聚与地区间工资差异

基于劳动力、产业在地区间分布的不平衡性以及地区间工资差异的事实,本文构建了一个市场潜力与工资的新经济地理学(NEG)理论模型。理论分析表明:市场潜力对工资产生正面影响。市场潜力对工资产生正面影响来自两种渠道:一是市场潜力引发了经济集聚效应;二是市场潜力产生了逆经济集聚。相比之下,市场潜力引发了经济集聚效应更能提高和扩大地区工资水平与差异,因为经济集聚需要更低的贸易成本、较大的市场规模以及较高的经济发展水平。     

皖江城市带城市经济联系与中心城市辐射范围分析

分析经济区内城市间经济联系不仅有利于引导城市的空间发展,而且有利于空间经济的合理组织。以皖江城市带为例,引入克鲁格曼指数、建成区面积、人口素质权重系数等指标修正了以往的引力模型,并利用城市间的日发车班次数据对修正模型进行了检验。在此基础上,利用修正模型确定了各城市的主要对外联系方向及联系强度,采用断裂点公式计算了中心城市的吸引范围。结果表明:①皖江城市带内各城市对外经济联系强度差异较大;②各城市的主要联系方向呈现中心城市指向性和地域相邻指向性特征;③合肥和芜湖为皖江城市带的两个经济中心城市,它们的对外吸引范围较为狭小。     

DOES SIZE MATTER? THE INFLUENCE OF FIRM SIZE ON WORKING CONDITIONS,JOB SATISFACTION AND QUIT INTENTIONS

Using a detailed survey on Spanish workers, this paper investigates the relationship between firm size and working conditions, the extent to which firm size differences in workers' job satisfaction can be accounted for by differences in their work environment and the impact of firm size on workers' quit intentions. The results indicate that: (1) employees in larger firms face a worse work environment; (2) working in large firms significantly reduces job satisfaction when no controls for working conditions are included, but taking them into account makes differentials across size categories statistically insignificant; and (3) no systematic differences exist in intentions to quit across firm size categories, irrespective of conditioning on wages.
