A quantile regression approach for estimating panel data models using instrumental variables

We introduce a quantile regression approach to panel data models with endogenous variables and individual effects correlated with the independent variables. We find newly developed quantile regression methods can be easily adapted to estimate this class of models efficiently.     

Trade credit in SMEs: a quantile regression approach

This article analyses the determinants of the trade credit in Spanish manufacturing small and medium-sized enterprises (SMEs) from a new perspective. Specifically, we focus on the relationship between trade credit and other relevance financial resources: bank credit and self-financing. For the first time in the literature, a quantile regression approach is used, which takes into account the heterogeneity of firms in different quantiles of trade credit distribution. Our results show that the relationship between trade credit and other financial sources presents dissimilarities, including differences in sign, on SMEs with different degrees of trade credit. Our findings help to clarify the confusing results achieved in previous research on this topic.     

Financial stress,sovereign debt and economic activity in industrialized countries: Evidence from dynamic threshold regressions

We analyze how the impact of a change in the sovereign debt-to-GDP ratio on economic growth depends on the level of debt, the stress level on the financial market and the membership in a monetary union. A dynamic growth model is put forward demonstrating that debt affects macroeconomic activity in a non-linear manner due to amplifications from the financial sector. Employing dynamic country-specific and dynamic panel threshold regression methods, we study the non-linear relation between the growth rate and the debt-to-GDP ratio using quarterly data for sixteen industrialized countries for the period 1981Q1-2013Q2. We find that the debt-to-GDP ratio has impaired economic growth primarily during times of high financial stress and only for countries of the European Monetary Union and not for the stand-alone countries in our sample. A high debt-to-GDP ratio by itself does not seem to necessarily negatively affect growth if financial markets are calm.     

服务业发展与人均收入的关系:基于分位数回归的实证研究

利用118个国家和地区1980-2005年服务业发展和人均收入的非平衡面板数据,采用分量回归的方法,在Fuchs的基础上对两者的关系进行研究。结果发现,服务业就业比重和人均GDP之间存在着显著并且稳定的正相关关系,服务业就业比重随着人均GDP的增加逐渐提高,这与Fuchs研究结论相同;与Fuchs不同的是,本文通过分位数回归还可以看出人均GDP的需求效应在服务业发展的不同阶段的影响程度的变化。在服务业发展的较低阶段,人均GDP的需求效应对服务业发展的作用较大;在服务业发展的较高阶段,人均GDP的需求效应对服务业发展的作用相对较小。     

An Eastern and SME version of expatriate management: an empirical study of small and medium enterprises in Taiwan

This study, different from previous ‘individual level’ research, explored ‘company-level’ expatriate training, expatriation policies and the perceived willingness on the part of expatriates to take on an enhanced role in organizational performance. Based on data from 254 Taiwanese SMEs with foreign investments, an Eastern and SME version of expatriate management is presented. The most significant predictors of expatriate premature return and company sales are the ‘number of expatriates’ and ‘ratio of expatriates with managerial positions’. Companies that have a greater percentage of expatriates with spousal accompaniment experience more premature return while insufficient training explains lower company sales. Insights regarding regional expatriate differences and methodological implications are also elaborated.     

计划生育政策如何影响城乡收入差距——基于CFPS数据的实证分析

基于CFPS（2010）数据,实证分析计划生育政策对城乡收入差距的影响机制,并利用Oaxaca-Blinder分解法和RIF回归分解法测度了计划生育政策对城乡收入差距的贡献度。结果表明：（1）计划生育政策有利于子代收入的提高,且对城镇的收入边际效应大于农村;（2）政策允许家庭生育数量越多,越不利于农村家庭子代收入的提高,家庭一旦超生则会显著降低子代收入,而且相对于农村家庭子代而言,城镇家庭超生对子代收入的负向影响更大;（3）计划生育政策对城乡收入差距的拉力呈现出U型特征,对低、高收入群体的影响较大,而对中等收入人群的城乡收入差距贡献相对较小,其中政策允许生育胎数起到了决定性作用。因此,计划生育政策应统筹全局、因地制宜、奖惩兼施,以提高农村的人力资本水平和子女的教育质量,促使城乡居民生育率和人力资本水平趋同。     

What's in a broken promissory obligation? Developing and testing a multiple component form measure of psychological contract breach

While the literature has suggested the possibility of breach being composed of multiple facets, no previous study has investigated this possibility empirically. This study examined the factor structure of typical component forms in order to develop a multiple component form measure of breach. Two studies were conducted. In study 1 (N = 420) multi-item measures based on causal indicators representing promissory obligations were developed for the five potential component forms (delay, magnitude, type/form, inequity and reciprocal imbalance). Exploratory factor analysis showed that the five components loaded onto one higher order factor, namely psychological contract breach suggesting that breach is composed of different aspects rather than types of breach. Confirmatory factor analysis provided further evidence for the proposed model. In addition, the model achieved high construct reliability and showed good construct, convergent, discriminant and predictive validity. Study 2 data (N = 189), used to validate study 1 results, compared the multiple-component measure with an established multiple item measure of breach (rather than a single item as in study 1) and also tested for discriminant validity with an established multiple item measure of violation. Findings replicated those in study 1. The findings have important implications for considering alternative, more comprehensive and elaborate ways of assessing breach.     

云南省城镇居民消费与收入关系的非参数回归分析

近二十多年来,非参数统计的方法已广泛应用于计量经济学的研究。由于不需要预先确定变量间的函数关系,对计量经济模型的估计和预测提供了多方面和灵活机动的表现形式。本文尝试将非参数估计理论引入到回归模型中,通过建立非参数回归模型及普通的线性回归模型对云南省城镇居民可支配收入及消费之间的关系进行比较研究。     

The effects of news events on market contagion: Evidence from the 2007–2009 financial crisis

In this paper, we use the quantile regression technique along with coexceedance, a contagion measure, to assess the extent to which news events contribute to contagion in the stock markets during the crisis period between 2007 and 2009. Studies have shown that, not only the subprime crisis leads to a global recession, but the effects on the global stock markets have also been significant. We track the news events, both in the UK and the US, using the global recession timeline. We observe that the news events related to ad hoc bailouts of individual banks from the UK have a contagion effect throughout the period for most of the countries under investigation. This, however, is not found to be the case for the news events originating from the US. Our findings regarding the evidence of contagion effects in the UK reinforce the argument that spreads and contagion—an outcome of the risk perception of financial markets—are solely a result of the behaviour of investors or other financial market participants.     

黑龙江省政策性农业保险影响因素实证分析

通过运用C-D函数对影响黑龙江省农业保险发展的一般因素以及模型外影响黑龙江省农业保险的发展因素进行回归分析,可以看出,影响黑龙江省农业保险发展的因素是农业增加值和政府财政补贴。为促进黑龙江省政策性农业保险的健康发展,应采取加快推进农业现代化进程、优化政府的政策性支持体系、多种渠道促进农民增收、加大保险宣传力度等对策。
