Islamic and conventional portfolios optimization under investor sentiment states: Bayesian vs Markowitz portfolio analysis

This paper investigates the portfolio optimization under investor’s sentiment states of Hidden Markov model and over a different time horizon during the period 2004–2016. To compare the efficient portfolios of the Islamic and the conventional stock indexes, we have employed two approaches: the Bayesian and Markowitz mean-variance. Our findings reveal that the Bayesian efficient frontier of Islamic and conventional stock portfolios is affected by the investor’s sentiment state and the time horizon. Our findings also indicate that the investor’s sentiment regimes change the Islamic and the conventional optimal diversified portfolios.Moreover, the results show that the potential diversification benefits seem to be more important when using the Bayesian approach than when applying the Markowitz approach. This finding is valid for the bearish, depressed, bullish and calm states in Islamic stock markets. However, the diversification of potential portfolios is significant only for the bullish and the bubble states in the conventional financial markets.The findings of the study provided additional evidence for investors to exploit googling investor sentiment states to evaluate the portfolio performance and make an optimal portfolio allocation.     

Internal pyramid structure,contract enforcement,minority investor protection,and firms’ performance: Evidence from emerging economies

This study investigates the relationship between internal pyramid structure and performance of Chinese, Pakistani, Malaysian pyramidal firms, the effect of judicial efficiency and minority investor protection on this relationship. The results show that the pyramid structure of Pakistani firms is more complicated than Chinese and Malaysian firms, both vertically and horizontally. The study finds that the impact of control layers on performance is negative and stronger than control chains. Moreover, the results illustrate that the effect of control layers on performance at Chinese firms is negative but lower than at Pakistani and Malaysian firms. However, control chains have insignificant association with performance at Chinese pyramid firms. We find that efficient judiciary abates the negative impact of control layers and chains on performance. Our results reveal that in the absence of efficient courts the minority investors’ protection have insignificant impact on the association between internal pyramid structure and firms’ performance.     

Selective disclosure and the role of Form 8-K in the post-Reg FD era

We investigate the impact of Form 8-K filings on cross-firm differences in analysts’ private or idiosyncratic information in the post-Reg FD era. Using firms’ connections to the investment community to identify the likelihood of selective disclosure, we document differences in analysts’ idiosyncratic information arising from selective disclosure before 8-K filings. While filings of 8-Ks pursuant to Reg FD attenuate the link between connections and analysts’ idiosyncratic information, they do so only after selective disclosures have already resulted in some analysts having better private information. In addition, the connections continue to facilitate private information search after the filings of non-Reg FD-specific 8-Ks.     

农村集体经济组织与农民专业合作社协同扶贫模式创新:重庆例证

农村集体经济组织和农民专业合作社是与农民联系较为紧密的两类经济组织,是贫困地区打赢脱贫攻坚战的重要内生性力量。但在实践中,受农村集体经济组织市场主体地位不明确、承担市场经营风险能力弱及农民专业合作社总体规模偏小、脱贫带动力不强等因素影响,两类主体的扶贫作用都未能得到充分发挥。重庆市城口县是国家扶贫开发工作重点县,在近年来的脱贫攻坚中,一方面普遍性地成立了新型农村集体经济组织,作为承接相关政府部门扶贫资源、开展村集体资产运营管理的平台;另一方面通过平等协商将村集体经济组织承接的扶贫资源以入股方式投入当地运行规范、实力较强的农民专业合作社,以获取相对稳定的分红收益,并优先用于增加贫困户收入。该模式既为村“两委”参与市场活动和承接政府扶贫资源提供了有效载体,又较好地保证了农民专业合作社等市场主体的经营自主权,有利于构建激励兼容、多方共赢的长效扶贫机制,是有镜鉴价值的扶贫模式创新。     

农户参与乡村旅游扶贫的影响因素研究——以福建省赤溪村为例

以福建省赤溪村农户为调研对象,运用相关性检验和二元Logistic回归模型对影响农户参与乡村旅游扶贫的因素进行研究。研究发现:农户参与乡村旅游扶贫的比例较高,但是旅游经营的项目单一;农户的学历、劳动力数量、地理位置、参与乡村旅游扶贫培训的次数对农户参与乡村旅游有显著地正向影响作用;农户生计资本和对旅游发展的感知中的权力关系、可借款能力、家庭年收入、了解乡村旅游扶贫政策、有资源用于发展乡村旅游也是影响农户参与的主要因素。在此基础上,提出了加大扶贫政策宣传力度,提高旅游扶贫政策利用程度完善旅游相关基础设施,扩大农户扶贫资金来源渠道,完善扶贫资金体系,完善旅游供给侧创新旅游经营模式,实行多项扶持的针对性建议。     

绿色信贷如何影响银行财务绩效——基于地区绿色发展异质性的视角

基于2007~2017年中国34家商业银行非平衡面板数据，实证检验了商业银行开展绿色信贷对其财务绩效的影响，并利用《中国绿色发展指数报告》提供的分省绿色发展指数，考察了绿色发展对绿色信贷与银行财务绩效关系的调节效应。结果表明：商业银行发放绿色信贷投放有助于改善其财务绩效，并且这种改善效应主要来自绿色信贷对银行生息资产收益率的提升作用；绿色发展水平能够增强银行投放绿色信贷的经济效益，并且这种增强效应主要与地方经济增长绿化度和地方政府对绿色发展的支持度有关。商业银行应积极开展绿色信贷业务；政府部门应加强和完善绿色信贷激励政策，以推动绿色金融与绿色经济协同发展。     

非公允关联交易中董事责任问题研究——兼评世行营商环境评估之董事责任程度指标

在关联交易中,对关联董事的追责应采用忠实义务标准。然而,当前立法存在"程序公平倾向"以及"忠实义务追责标准狭窄"的问题,导致无法对已履行法定程序的关联董事进行追责。对此应将忠实义务下追责标准改为全面公平标准,对关联董事课以承担非公允关联交易中公司所受损失的义务;对非关联董事的追责应采用勤勉义务标准。因为当前立法过于原则化,缺乏适用空间,所以应在信义义务两分法下积极拓展勤勉义务即"知情"的基础上决策的内涵,衍生出对于公司造成损失的直接故意、间接故意以及重大过失三种追责情形,以弥补董事问责空隙,并将"商业判断规则"作为法院介入而非排除审查的判断标准,进一步激活董事追责的路径。

Corporate brand strategy: Drivers and outcomes of hotel industry’s brand orientation

The MNC resellers are vastly competitive and capital-intensive. Based on the corporate brand orientation, the objective is to investigate how the individual dimensions of hotel industry’s brand orientation can improve a corporate experience and subsequently create superior hotel performance and retailer preferences. A model of the integration of the hotel industry’s brand orientation was tested in a survey conducted among MNC resellers from hospitality industry. Structural equation modelling was applied to gain insight into the various influences and relationships. The research makes two main contributions. It makes a theoretical contribution by classifying the integration of the hotel industry’s brand orientation for hospitality industry and from this extrapolate key suggestions for further study. The continuous evolution and economic influence of the hospitality industry require the application of innovative marketing practices.
