Ethnic Discrimination in Germany's Labour Market: A Field Experiment

Abstract. This paper studies ethnic discrimination in Germany's labour market with a correspondence test. We send two similar applications to each of 528 advertisements for student internships, one with a Turkish‐sounding and one with a German‐sounding name. A German name raises the average probability of a callback by about 14%. Differential treatment is particularly strong and significant in smaller firms at which the applicant with the German name receives 24% more callbacks. Discrimination disappears when we restrict our sample to applications including reference letters which contain favourable information about the candidate's personality. We interpret this finding as evidence for statistical discrimination.     

‘Whatever it takes’ and the role of Eurozone news

This letter shows that the ‘Whatever it takes’ speech by ECB President Draghi on 26 July 2012 and the ensuing installation of the Outright Monetary Transactions’ framework are associated with a reduction in the domestic and cross-border effect of Eurozone news on absolute yield changes in Eurozone sovereign debt. These results are consistent with the popular view that these actions helped to avoid a collapse of the Eurozone.     

某工程混凝土强度不足的原因和事故处理方法

某商场为4层框架结构,在施工过程中经检测部分区域梁、板、柱混凝土强度偏低,根据混凝土回弹及取芯的强度试验报告、水泥安定性和缓凝减水剂试验报告,分析得出混凝土强度不足的原因为缓凝减水剂质量不合格,并结合工程实际,提出了加固处理方案。目前该工程加固已经完工并通过验收,2年来运行良好。     

Structural changes and regional disparity in China's inflation: a revisit

The study re-examined the time series properties and regional disparities in Chinese inflation by extending the work of Chong, Zhang, and Feng (2011 Chong, Tai-Leeung, Terence, Ning Zhang and Feng, Qu. 2011. Structural Changes and Regional Disparity in China's Inflation. Economics Bulletien, 31(1): 572–583.  [Google Scholar]). For this purpose we employed the Lagrange Multiplier (LM) unit root test with one structural break and two structural breaks suggested by Lee and Strazicich (2003 Lee, Junsoo, Mark, C. and Strazicich. 2003. Minimum LM Unit Root Test with Two Structural Breaks. Review of Economics and Statistics, 85(4): 1082–1089. [Crossref], [Web of Science ®] , [Google Scholar], 2004 Lee, J. and Strazicich, M. 2004. Minimum LM unit root test with one structural break. Working Paper 04–17, Boone, North Carolina: Department of Economics, Appalachian State University.  [Google Scholar]) and a recently developed ADF type unit root test with two structural breaks of Narayan and Popp (2010 Narayan, Paresh Kumar and Stephan Popp. 2010. A New Unit root test with Two Structural Breaks in Level and Slope at Unknown Time. Journal of Applied Statistics, 37(9): 1425–1438. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). We found that national, urban and rural series of the overall inflation series, clothing, and food, national series of education and residence and the rural series of residence and education are stationary. We also found regional disparity in Chinese inflation, but the disparities existed only in education inflation series.     

R＆D、R＆D溢出、内生增长和内生收敛

根据强调知识与技术创新、知识与技术溢出重要性的当代内生增长理论，本文建立了一个将R＆D和R＆D溢出与资本积累之间、R＆D和R＆D溢出与总产出增长之间直接关联起来的动态模型。面板数据协整检验实证分析结果表明R＆D和R＆D溢出与资本积累之间、R＆D和R＆D溢出与总产出增长之间分别存在显著的正面长期协整关联。进一步的分析表明，R＆D与资本积累之间、R＆D与总产出增长之间分别存在显著的长期双向格兰杰因果关系。由此观知，R＆D乃长期经济增长源泉之所在。另一方面，尽管资本积累或总产出增长并不格兰杰导致R＆D溢出，证据表明R＆D溢出格兰杰导致资本积累和总产出增长。这种由R＆D溢出到资本积累和总产出增长的单向格兰杰因果关系意味着尽管知识与技术的跨国传播并非必然发生。其实为世界经济增长的重要动力。     

广东省对外贸易与经济增长关系的实证研究

以广东省1987～2008年的相关数据,综合运用平稳性检验、协整检验、VAR模型和Granger因果关系检验等计量方法,对广东省对外贸易与经济增长之间的关系进行了实证分析。根据分析得出广东省对外贸易与经济增长之间的定量关系,以期能为政策制定者提供一定的参考依据。

揭示"制度与增长关系之谜"的一个研究视角——基于中国经济转型与经济增长关系的实证研究(1978-2004)

本文通过对中国经济转型与经济增长之间的实证研究,发现经济增长是直接推动经济体制转型深化的内在动力,而经济转型虽然对经济增长有长期的影响作用,但这种作用却不是决定性的.在制度与增长二者关系中,制度虽然是影响增长的长期重要因素,但这种影响却不是决定性的;而恰恰相反,增长对制度的影响却是决定性的.这说明制度创新在增长的大背景中更易达到,而中国改革成功的经验也充分证明了这一点.     

美中贸易收支与人民币汇率关系:实证分析

针对美中贸易收支与人民币汇率问题,经研究发现,汇率变动对贸易收支的影响是值得怀疑的,仅仅依靠人民币汇率变动是无法解决美中贸易逆差问题的。1994—2002年年度数据实证显示,美中贸易收支与人民币汇率(名义或实际汇率)之间没有稳定的关系;1998—2003年月度数据计量表明,美中贸易收支与人民币汇率之间没有长期稳定的协整关系。并且,依据美中两国月度统计数据计量的结论是相一致的。因此,“人民币升值论”或许更多的是基于政治而非经济因素,人民币汇率浮动并不能解决美中贸易逆差问题。     

Nonlinear Mean Reversion across National Stock Markets: Evidence from Emerging Asian Markets

This paper seeks empirical evidence of nonlinear mean-reversion in relative national stock price indices for Emerging Asian countries. It is well known that conventional linear unit root tests suffer from low power against the stationary nonlinear alternative. Implementing the nonlinear unit root tests proposed by Kapetanios et al. (2003 Kapetanios, G., Shin, Y. and Snell, A. 2003. Testing for a unit root in the nonlinear STAR framework. Journal of Econometrics, 112: 359–379. [Crossref], [Web of Science ®] , [Google Scholar]) and Cerrato et al. (2009 Cerrato, M., de Peretti, C., Larsson, R. and Sarantis, N. 2009. “A nonlinear panel unit root test under cross section dependence”. Working Papers 28, Department of Economics, University of Glasgow [Google Scholar]) for the relative stock prices of Emerging Asian markets, we find strong evidence of nonlinear mean reversion, whereas linear tests fail to reject the unit root null for most cases. We also report some evidence that stock markets in China and Taiwan are highly localized.
