The Fisher Equation: A Nonlinear Panel Data Approach

This article reinvestigates the Fisher equation. Using the panel smooth transition regression (PSTR) model, it was found that there is a significant regime-switching effect concerning the impact of inflation on interest rates. Specifically, inflation is found to raise the interest rates and the effect becomes stronger in magnitude with inflation. However, the data do not provide evidence in support of the one-for-one Fisher effect. The evidence is robust to interest rates with different maturities and subsamples.     

银行信贷、房地产价格与经济增长的非线性关系研究——基于省际面板平滑转换模型的实证检验

选用中国2000~2014年31个省的面板数据,以银行信贷为转换变量,通过构建面板平滑转换模型对我国房地产价格与经济增长的非线性关系进行考察。研究发现：当信贷增长率低于28.74%时,房价增长率对经济增长产生比较显著的正向影响;当信贷增长率高于28.74%时,房价增长率对经济增长起到了明显的阻碍作用。因此,为了实现“稳定房价和保持经济平稳增长”的目标,央行应将信贷增速维持在低增长体制的最优区间中。同时,央行还应该改善信贷结构,鼓励和引导金融资源进行合理配置。     

Empirical Analysis of the Relationship between the Level of Urbanization and Economic Growth

本文利用一个城市化水平内生增长模型,借助非平稳面板数据的方法,考察了中国省际城市化水平与经济增长之间的关系。结论表明,虽然中国整体的城市化水平比较低,需要通过提高城市化水平来促进经济增长,但并不是所有省份的城市化水平提高都能促进经济增长,某些省份存在着相对于经济增长的过度城市化问题,其城市化水平的提高对经济增长起负向作用,而且过度城市化的负面效应会抵消投资所带来的效应。     

基于面板数据模型的信贷支持县域经济增长实证研究——以广西百色为例

本文利用面板数据模型对百色市11个县银行贷款和经济增长的关系进行了实证分析,结论表明信贷对县域经济增长有明显的促进作用。     

中国各地区金融发展与经济增长的关系分析

本文通过对全国31个省市自治区1978-2008年的金融发展与经济增长的面板数据分析发现:金融发展与经济增长总体呈现很强的正相关,但由于各地的经济基础不同,各地区之问差异较大.总体来说,东部地区金融发展对经济增长的推动作用较强,而中西部地区金融发展对经济增长的促进作用较弱,这可以解释为较高的金融发展水平对经济增长的促进作用就较强.因此,政府应加大对中西部资金支持和政策倾斜力度.     

制度、增长与收敛——一个基于索洛模型的分析框架

标准的经济增长理论把制度看作是既定不变的并且不存在交易费用的,所以无法认识到制度对经济增长的重要性.将制度作为一个变量引入索洛模型,可以构造一个包含制度的、技术内生的增长模型.通过模型的推导可以得出这样的结论:制度质量越好,人均产出增长率越高;人均产出存在关于制度的条件收敛.并进一步得出这样的推论:欠发达国家想获得"后发优势"赶超发达国家,前提条件是具备良好的制度或能够持续改善其制度.     

Financial Stress Regimes and the Macroeconomy

Some financial stress events lead to macroeconomic downturns, while others appear to be isolated to financial markets. We identify financial stress regimes using a model that explicitly links financial variables to macro‐economic outcomes. The stress regimes are identified using an unbalanced panel of financial variables with an embedded method for variable selection. Our identified stress regimes are associated with corporate credit tightening and with NBER recessions. An exogenous deterioration in our financial conditions index has strong negative effects in economic activity, and negative amplification effects on inflation in the stress regime. These results are obtained with a novel factor‐augmented vector autoregressive model with smooth‐transition regimes (FASTVAR).     

后危机时代政府干预与银行信贷—基于国有经济视角

本文利用我国2007-2016年的省级面板数据,对后危机时代政府干预与银行信贷以 及不良贷款率进行了实证研究。本文发现：地方政府干预显著带来地区信贷增长以及不良贷款 率下降;地方政府通过对国有经济进行干预,可以显著带来地区信贷增长,但对降低地区不良 贷款率不显著。进一步研究发现：东部地区政府干预有助于提高地区信贷增长并降低不良贷款 率;西部地区政府通过干预国有经济能带来地区信贷增长;无论是东部、中部还是西部,政府 通过对国有经济的干预降低地区不良贷款率均不会产生太大效果。     

地方政府公共投资与区域经济增长的差异性分析

文章采用全国31个省、自治区和直辖市1995~2008年的面板数据,构建动态面板数据模型,考察了地方政府公共投资对区域经济增长的影响。研究表明,1995年以来我国地方政府公共投资总体上推动了区域经济增长,但不同公共投资项目的拉动效应在区域间存在着较大差异。     

能源效率、环境污染与中国经济发展方式转变

以往研究虽然关注了能源效率与经济发展之间的关系,但却忽略了能源利用过程中环境污染的改善对经济发展方式转变的影响。本文将环境变量纳入能源效率分析框架内,采用EBM-DEA模型测算了中国各地区能源效率,并利用动态空间面板模型,实证考察了环境约束下的能源效率对中国经济发展方式转变的影响。研究结果显示,中国经济发展方式具有明显的空间相关性和路径依赖性;与未考虑环境污染相比,环境约束下的能源效率对经济发展方式转变的影响更为明显,这也在一定程度上表明,如果不考虑能源效率提升的环境污染改善效应,将会低估其对经济发展方式转变的影响。本文结论为提升中国能源效率水平,加快经济发展方式转变提供政策启示。     

How should we estimate value-relevance models? Insights from European data

We study the consequences of unobserved heterogeneity when employing different econometric methods in the estimation of two major value-relevance models: the Price Regression Model (PRM) and the Return Regression Model (RRM). Leveraging a large panel data set of European listed companies, we first demonstrate that robust Hausman tests and Breusch-Pagan Lagrange Multiplier tests are of fundamental importance to choose correctly among a fixed-effects model, a random-effects model, or a pooled OLS model. Second, we provide evidence that replacing firm fixed-effects with country and industry fixed-effects can lead to large differences in the magnitude of the key coefficients, with serious consequences for the interpretation of the effect of changes in earnings and book values per share on firm value. Finally, we offer recommendations to applied researchers aiming to improve the robustness of their econometric strategy.     

Smooth Transition ARCH Models: Estimation and Testing

In this paper, we suggest an extension of the ARCH model, the smooth-transition autoregressive conditional heteroskedasticity (STARCH) model. STARCH models endogenously allow for time-varying shifts in the parameters of the conditional variance equation. The most general form of the model that we consider is a double smooth-transition model, the STAR-STARCH model, which permits not only the conditional variance, but also the mean, to be a function of a smooth-transition term. The threshold ARCH model, the Markov-ARCH model and the standard ARCH model are special cases of our STARCH model. We also develop Lagrange multiplier tests of the hypothesis that the smooth-transition term in the conditional variance is zero. We apply our STARCH model to excess Treasury bill returns. We find some evidence of a smooth transition in excess returns, but in contrast to previous studies, we find almost no evidence of volatility persistence once we allow for smooth transitions in the conditional variance. Thus, the apparent persistence in the conditional variance reported by many researchers could be a mere statistical artifact. We conduct in-sample tests comparing STARCH models to nested competitors; these suggest that STARCH models hold promise for improved predictions. Finally, we describe further extensions of the STARCH model and suggest issues in finance to which they might profitably be applied.     

房价波动、银行信贷与经济增长

运用联立方程模型、面板分析技术及省际面板数据研究发现,我国房价波动、银行信贷与经济增长之间具有紧密的联系.分区域的实证研究结果显示:各地区房价的上涨与金融支持有关,过度的金融支持使东中部地区的房价偏离了经济基本面;中西部地区房价的上涨对银行信贷的扩张有显著影响,而经济增长是各地区促进银行信贷扩张的共同因素.此外,房价的上涨与银行信贷的扩张共同促进了我国各区域经济的繁荣.     

长期资金市场对能源强度的影响研究——基于中国省际面板数据的实证分析

依据中国30个省(市)自治区1998~2013年面板数据,考量长期资金市场对能源强度的影响。结果表明,长期资金市场发展对东部地区能源强度下降影响较大,产业结构升级、人均 GDP 提高均有利于各地区能源强度下降,技术进步、对外贸易度对各地区能源强度的影响呈现出分化态势。鉴此,应充分发挥长期资金市场优势、促进产业结构升级、重视研发投入产出技术成果转化等,多渠道降低能源强度。
