Incentives to move up: Effects of pay gaps between levels on employee performance

Employees of a certain rank are motivated by the pay gap between them and the levels above (upward comparison), and the pay gap between them and the levels below (downward comparison). In some cases, employees face multiple upward comparisons such as immediate and subsequent upward comparisons. We hypothesise that upward comparison matters more than downward comparison, and in the case of multiple upward comparisons, the immediate one matters more than the subsequent ones. We also hypothesise that the pay gap effect resulting from the upward/downward comparison ought to be non‐linear in that performance increases with pay gap size at a decreasing rate. The results from two empirical studies, namely, a longitudinal field study and a laboratory experiment, largely support our hypotheses.     

不同利率对我国上市银行信用风险的影响

对我国16家上市银行进行的实证检验表明：3个月同业拆借利率与银行信用风险显著正相关，人民币5年期基准存款利率与银行信用风险的关系不确定，人民币1年期基准存款利率与银行信用风险显著正相关，贷款利息收入占贷款比例与银行信用风险显著负相关。

全球城市的经济地位研究

全球城市成为认识全球经济的一个视角,越来越多的研究聚焦全球城市,这既反映了世界经济的新变化,也反映了城市发展的新变化。经济全球化的"分离"和"集聚"打造了全球城市。信息技术成为全球城市的技术基础。全球城市网络成为全球城市的外部条件。全球公司占据全球城市的关键地位。全球城市的意义在于服务于全球经济,其服务的属性是生产性服务,主要形式是商务服务和金融服务。全球城市驱动全球经济,全球城市集聚一国的经济能量,全球城市应该成为中国经济的一个方向。全球城市已经成为北京上海的发展目标。     

对南海国际争端的经济学解析

我国地处东亚的中心,是一个陆海大国,与周边各国有着漫长的边界线,地缘环境非常复杂,形势十分严峻。近些年,随着我国综合国力的逐渐壮大,以及国际格局和地区形势的变化,我国的周边安全环境进一步缓和。而南海,其独特的地理位置和战略位置决定了它的重要性。当今的南海格局被称作六国七方,南海争端涉及到诸多国家的政治、经济利益,主权、领土的争端以及运输通道和能源安全等问题。本文从博弈学和经济学的角度分析南海现状的成因,并就解决南海问题的政治经济对策进行探析。     

Disclosure of Downside Risk and Investors' Use of Qualitative Information: Evidence from the IPO Prospectus's Risk Factor Section

I use the context of a company's initial public offering (IPO) of equity securities as a capital‐market setting to empirically study the economic consequences of risk factor disclosures. Using data from Australian IPOs, I examine the relation of textual risk disclosures in the prospectus to initial underpricing. I find that the quantity of disclosures in the risk factor section itself has no significant impact on initial underpricing. However, an increase in the informativeness of risk factor disclosures is associated with lower IPO underpricing. My results suggest that IPOs that provide informative risk factor disclosures have less ex ante uncertainty, in the sense that the disclosures help investors estimate the dispersion of secondary market value. The effect of informative risk factor disclosures on IPO underpricing is more pronounced for IPOs with less prestigious lead underwriters and is mainly driven by younger firms, smaller firms, and firms with poorer operating performance prior to their IPOs. Collectively, my findings suggest that informative disclosures of downside risk are useful for investors to evaluate IPOs.     

河南省农业面源污染成因分析

近年来,农业面源污染给我国农村生态环境造成了一定的破坏,挖掘农业面源污染的成因及问题对今后农业面源污染的治理具有重要意义。文章以河南省为探讨对象,首先阐述了农业面源污染含义及主要特点。利用文献分析和统计方法对河南省农业化学品投入使用及污染情况进行分析,2007~2014年河南省化肥及农药产量和使用量均呈上涨趋势,污染面积及范围进一步扩大,面源污染的主要来源是化肥、农药、秸秆及生活垃圾。而人口快速增长、经济利益驱使、政策方面不健全是造成农业面源污染主要原因。该文认为,解决农业面源污染应从推广减量技术,积极发展有机(生态)农业;提高思想认识,树立科学农业发展理念;大力推广精准农业,减轻面源污染程度;建立健全环境法规,完善政策及管理体系等4个方面入手,以期为其他地区农业面源污染治理提供借鉴和参考。     

基于耦合协调度模型的南京市用水效率与经济发展关系

基于2007—2014年南京市用水效率与经济发展的时间序列数据,构建南京市用水效率系统与经济发展系统间的耦合协调度模型,探讨南京市在2007—2014年期间用水效率与经济发展之间的动态均衡关系。首先对用水效率系统和经济发展系统的综合状况进行评价,然后对两系统的耦合协调度进行定量分析。结果表明:2007—2014年南京市用水效率和经济发展水平都有大幅度增长;两者的耦合协调关系在波动中逐渐优化,2007年处于低度协调耦合阶段,2008年处于中度协调耦合阶段,2009—2014年处于高度耦合协调阶段;只有提高用水效率与经济发展并举,才能保持耦合协调度的增长趋势。最后针对用水效率系统和经济发展系统存在的不足,提出在用水效率方面优化用水结构、加强水质污染治理,经济发展方面则调整经济结构、增强经济活力等建议。     

Does international capital flow lead to a housing boom? A time-varying evidence from China

This paper examines the causal relationship between the housing prices (HP) and the international capital flows (ICF) in China. With structural changes existing, we find that long-run relationship using full-sample data is unstable, suggesting that traditional Granger causality test is not reliable. However, we further find an unstable short-run relationship between ICF and HP when assessing the stability of the parameters and there are bidirectional causal relationships between ICF and HP for several sub-periods. Additionally, our findings indicate both positive and negative bidirectional causal relations between the series. Based on the arbitrage of ICF, the results suggest that the rise of Chinese HP is the underlying force for the inflows of international capital. Meanwhile, a surge in capital inflows may be accompanied by a rise in the price of housing. This confirms the theoretical analysis that there is an interconnected transmission mechanism between the ICF and the HP, which is diverse and depends both on the flow of ICF and on other factors.
