Glamour and Value Strategies on the Tokyo Stock Exchange

This paper evaluates the performance of glamour and value strategies and tests the extrapolation model for the Japanese equity market. In general, value stocks outperform glamour stocks by between 6 and 12 percent per annum for the five years after portfolio formation. Evidence from past, future and expected growth provides strong support for the story developed in Lakonishok, Shleifer and Vishny (1994). It is difficult to attribute the value premia to the difference, if any, in risk factors. In addition, the book-to-market premium is much closer to an arbitrage opportunity than the size premium.

Dynamic relationship between stock market trading volumes and investor fear gauges movements

This article applies multifractal detrended fluctuation analysis (MF-DFA) and multifractal detrended cross-correlation analysis (MF-DCCA) to investigate cross-correlation behaviours between two kinds of stock markets trading volumes and investor fear gauges covering the data of U.S. stock markets from 2 January 2004 to 31 July 2018. The empirical results show that the dynamic relationship between stock markets trading volume fluctuations and different kinds of investor fear gauges are multifractal and find that the dynamic relationship is strongly anti-persistent. Moreover, financial crisis in 2008 has a significant impact on the cross-correlated behaviour, suggesting that stock market trading volume fluctuations and investor fear gauges are more susceptible to each other during the financial crisis period. Through the rolling windows analysis, we also find that the stock markets trading volume fluctuations and different kinds of investor fear gauges are anti-persistent dynamic cross-correlated.     

责任式创新研究的时空向度透视与知识框架建构

在科技社会深度融合发展的背景下,聚焦责任式创新,以2009―2020年WOS和CNKI数据库中879篇文献为样本,综合运用文献计量分析、因子分析和多维尺度分析,从时间和空间视角探索责任式创新研究的外部特征、热点内容、前沿趋势,并构建该领域知识框架。研究结果表明：①近12年国内外研究发文量总体呈上升趋势,但国内研究热度较低且尚处于初始阶段,国外科研合作网络紧密,积极推动该领域研究发展,同时该领域研究呈现跨学科特征,并逐渐形成学科交叉下的知识流动路径;②研究热点可分为4个方面,即内涵及理论框架构建研究,责任式创新与利益相关者参与研究,责任式创新跨界结合研究,责任式创新方法、实践及评估研究,研究前沿趋势可分为3个方面,即责任式创新与伦理规范研究、责任式创新与新兴技术治理研究、责任式创新的社会嵌入与政治议程研究;③基于因子分析和多维尺度分析,构建责任式创新的“情境―理论内涵―干预―机制―结果”CTIMO知识框架。最后,从责任式创新的制度情境、实践及扩散、利益相关者管理、组织层面评估等方面提出未来研究展望。     

Public–Private Sector Wage Gap in Australia: Variation along the Distribution

Previous research on public–private wage differentials in Australia has focused on the mean of the conditional wage distribution. Using six waves of the Household, Income and Labour Dynamics in Australia survey, this study employs quantile regressions to examine whether the sectoral wage effect varies along the wage distribution. For females, public sector wage premiums are relatively stable for almost the entire distribution. For males, they decrease monotonically and are negative for the top half of the distribution. The decomposition results show that the observed differences in individuals and job characteristics explain a substantial proportion of the sectoral wage gap.
