Remark on a theorem by Gurland

Abstract

Let X ₁,X ₂,...,X _n be a random sample of size from a distribution with probability density function p(x|θ), where the unknown parameter θ belongs to a non-degenerate interval I. The unknown true value of θ will be denoted by θ₀.     

控制权及投资者保护对掏空风险的影响——基于融资规模的经验证据

基于中国上市公司融资规模数据对上市公司的控制权与掏空风险的关系进行了实证分析,并探讨了投资者保护对掏空风险的抑制作用。研究发现:与国家终极控制的上市公司相比,私人终极控制的上市公司中掏空风险更高,因而融资规模显著高于前者;控股股东持股比例越高,掏空上市公司的动机越小,从而导致上市公司融资规模越低;其他大股东的制衡能力越强,控股股东掏空上市公司的可能性越小,因而上市公司融资规模越低;投资者保护水平越高,越能起到抑制掏空风险的作用。     

The Doctrine of the Mean: Workplace Relationships and Turnover Intention

The present study examines the curvilinear relationships between LMX/TMX and team members' turnover intention simultaneously. That is, members with high LMX, TMX, or both are more likely to have turnover intention. Hypotheses were tested with a sample of 452 nurses, and we adopted the response surface methodology and polynomial regression to test our theoretical model. The hierarchical regression analysis showed that TMX has a U‐shaped relationship with turnover intention but not with LMX. In addition, the results indicate that both the congruence and incongruence of LMX and TMX result in higher turnover intention, but moderate levels of LMX and TMX have the lowest turnover intention. Strengths, limitations, practical implications, and directions for future research are discussed. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

货币政策与财政政策的区域产业结构调整效应比较

本文运用1978—2007年东、中、西部的面板数据分析。货币政策和财政政策是否具有区域产业结构调整效应结果显示:第一,财政政策具有产业结构调整效应,而货币政策的产业结构调整效应并不明显。第二,货币政策在对第一和第三产业的效应方面强于财政政策,而财政政策则在对第二产业的效应方面具有优势。第三,货币政策和财政政策对三次产业的效应都存在比较明显的区域效应。第四,在东部地区货币政策和财政政策对第一产业和第二产业的效应相差非常悬殊,而对第三产业的效应则集中在高位;在中部地区货币政策和财政政策对第二产业的效应集中在高位;在西部地区货币政策对第一产业的效应集中在高位,而财政政策对第一产业的效应则集中在低位。     

基于促进农村消费的城乡双向物流发展策略

农民收入的低水平,持续增收难度大,预期收入不确定和预期支出增加,城乡收入差距扩大,城乡双向物流发展滞后等因素制约了我国农村消费的增长。而城乡双向物流的发展能从增加农民收入,转变消费观念等方面促进农村消费。为此,应发挥政府的引导作用,加快农村基础设施建设,构建城乡一体化物流信息平台,培养农村物流专业人才,培育多元化的农村物流市场经营主体,创新城乡物流对接模式,促进城乡双向物流的发展。     

Shock-dependent conditional skewness in international aggregate stock markets

This article uses the S_U-normal distribution to model the dynamic behavior of skewness in ten international aggregate stock indices—five indices each from developed and emerging markets. The conditional skewness process is specified as both autoregressive and dependent on lagged return shocks. Our primary result is that a negative return shock skews the time-varying distribution to the right for mature markets but to the left for emerging markets. In addition, we find that the asymmetry in volatility is noticeably larger in developed markets than in emerging markets. Finally, including the skewness process in modeling has no effect on the asymmetry and persistence in volatility obtained. These results are different from those of previous studies, which demonstrate the existence of both effects.

Banks’ non-traditional activities under regulatory changes: impact on risk,performance and capital adequacy

Using the big six Canadian chartered banks quarterly financial statements and daily stock market data from 1982 to 2018, we examine the impact of non-interest income on Canadian banks’ risk, performance and capital under the different major regulatory changes made to the Bank Act of Canada. Our results show that Canadian banks’ expansion into non-traditional activities had slightly decreased their risks and significantly improved their performance benefitting from income diversification. Moreover, while adhering to capital adequacy regulation, reshuffling banks’ portfolio towards non-traditional activities did not reduce Canadian banks’ capital ratio. In spite of the re-regulation towards universal banking against ring-fencing, this feature buttresses the effectiveness of capital adequacy regulation in Canada in linking banks capital allocation with their risk taking.     

Institutional-based antecedents and performance outcomes of internal and external green supply chain management practices

Green supply chain management (GSCM) has been a developing topic for at least a couple of decades. Over this time, significant complexities have been observed in its management. Helping to simplify and understand these complexities is necessary from both a practical and research perspective. Given this situation and to further enhance understanding of the topic and even supply chain management in general, this paper develops and empirically tests a theoretical model on the different types of institutional pressures motivating manufacturing enterprises to pursue green supply chain management (GSCM) practices and commensurate performance outcomes. Using a sample of 396 Chinese manufacturers, path analysis is used to evaluate the many structural links. The statistic results show that institutional pressures have driven the manufacturer adoption of internal GSCM practices which in turn relate to their external GSCM practices adoption. The statistic results also suggest that GSCM practices do not directly affect economic performance, but can improve it indirectly. This research contributes to the literature on institutional theory in corporate environmental practices. The research findings provide useful insights for managers seeking to adopt GSCM practices. The results also provide policy insights for professional organizations, regulators, and legislators to further promote GSCM.
