Effects of investor tax heterogeneity on stock prices and trading behaviour around the ex-dividend day: the case of Australia

Using a sample of Australian stocks during the 1996–2014 period, this study examines how tax heterogeneity between domestic and foreign investors affects trading behaviour and stock prices around the ex-dividend day. Domestic investors prefer dividends and tend to buy stocks cum-dividend and sell them ex-dividend whereas foreign investors tend to trade in the opposite direction. Abnormal trading turnover increases with tax heterogeneity. Moreover, stocks with a larger domestic investor base are associated with a higher price drop-off ratio on the ex-dividend day and higher market value of franking credits. Overall, our findings support the dynamic dividend clientele hypothesis.     

The Moderating Impact of Family Role Configurations

This study examines the impact of across domain social support, work-family conflict (WFC) and job satisfaction, and explores the influence of family role allocations among these relationships. Family roles include breadwinner and caregiver. Direct effects were found for two types of support and both WFC and job satisfaction. Additionally, results provided some evidence that family roles moderated the support-outcome relationship, particularly for caregivers. The research and practical implications, as well as limitations of this study are discussed.

The Role of Financial Ratios in the Variance of Stock Trading Volume in Emerging Stock Markets

The study used quarterly panel data of 6 years from 2010 to 2015 of all companies listed on both Vietnamese stock markets including the Ho Chi Minh City Stock Exchange and Ha Noi Stock Exchange, and on three leading industries consisting of insurance-banking, foodstuff, and real estate to explore the relationship among four key financial ratios and stock trading volume. Two models, fixed effects model (FEM) and random effects model (REM), with robust standard errors, were applied for this study. The key findings showed that earnings before tax on sales, debt on owner’s equity, and owner’s equity on total assets significantly influenced trading volume.     

利用FDI促进我国自主创新的思路探讨

改革开放以来的30年时间里，外资经济已成为我国经济的一个重要组成部分，它为推动我国的经济发展做出了十分重要的贡献。然而。“利用FDI”与“自主创新”之间究竞存在怎样的关系，一直是学术界争论的焦点。文章从我国利用FDI的现状入手，分析了利用FDI对我国自主创新的影响，得出事实上利用FDI与自主创新之间并不矛盾的结论，并剖析出当前制约我国利用FDI提高自主创新能力的因素，进而提出我国应当如何提高FDI利用率来促进自主创新的思路。     

人民币购买力平价成立吗?——基于人民币兑欧元的多样本协整分析

选取人民币兑非主权国家货币——欧元的名义汇率,中国CPI指数及欧元区调和HICP指数的数据,以欧元正式成为欧元区唯一合法货币的起点2002年7月到2018年12月为样本,依据影响中欧汇率的重要节点事件对样本进行分段与结合,对人民币兑欧元购买力平价(PPP)成立与否进行协整检验。实证结论有:人民币汇率形成制度改革及欧元平稳运行后的(2005年8月—2018年12月)人民币兑欧元购买力平价协整检验成立;非主权国家货币欧元同样适用经典的购买力平价理论;2008年金融危机是影响汇率市场的重要节点事件,但长期不影响人民币兑欧元购买力平价成立;对PPP冲击影响最大的首先是汇率本身,其次依次是欧元区HICP、中国CPI。因此,购买力平价在一定程度上能够解释人民币兑欧元汇率,对中欧经贸往来有一定的指导作用。     

对湖南省银行卡用卡情况的调查与思考——以长、常、衡三市为例

湖南省无论从率先开展银行卡助农取款服务,还是推广银行卡升级换代等都取得了一定成就。但也存在着持卡人用卡情况仍欠佳、用卡领域狭窄、服务欠完善、环境欠佳、法规环境欠优化等诸多问题。已成为银行卡产业发展的瓶颈。改变信用卡发展严重滞后现状,增加居民收入与改变消费观念,加大银行卡推广力度,加快银行卡产品创新,创造良好的银行卡受理和法规环境。拓展并规范信用卡市场无疑是一条有效途径。同时,应大力培养消费者良好用卡理念,避免“睡眠卡”的出现,提高持卡人用卡频率,增强用卡安全意识。推动银行卡产业的发展。     

基于复杂多响应相关性的稳健性优化设计

本文对目前复杂多响应问题中,响应间相关性复杂问题的稳健性优化设计方法进行了分析和总结,考察了2种复杂多响应的稳健优化技术,比较了各种方法的特点同时又考虑了稳健性满意度函数法,并对其进行了优化。研究结果表明,最优化稳健性满意度函数法能够很好的平衡复杂多响应中的优化与稳健性的问题,可以很好的解决现代工业产品中只考虑最优化忽略稳定性而导致"召回门"不断的问题。     

寻找理性经济行为的逻辑新起点——试论中国传统伦理下的中庸理性经济人

在主流经济学的视野中,追求效用最大化是社会个体理性行为的基本准则。文章认为主流经济学理性假设的根本问题在于没有揭示特定人类社会的独特复杂特征。主流经济学家忽略了在现实生活中存在于西方文明之外的实然——中庸理性。文章尝试在以中庸理性为假设的理性经济人模型基础上,探讨中国传统伦理下中庸理性经济人的演化及其存在的可能空间。
