Many investors now factor in the long-term sustainability of successful and responsible companies when making their investment choices. The purpose of this paper is to investigate whether or not the sustainability performance of a company affects the informativeness of its earnings by exploring the mediating effect of sustainability performance on the association between stock returns and earnings changes.Design/methodology/approachUsing a sample of firms for the period 2009–2016 with available sustainability data from TruValue Labs' database, the authors investigate how the sustainability performance of a firm mediates the relationship between stock returns and earnings (changes). The authors use ordinary least squares (OLS) regressions to test their hypotheses.FindingsConsistent with the voluntary disclosure and environmental, social and governance (ESG) performance literature, the authors find that higher sustainability performance improves the stock price informativeness of earnings. The authors find evidence in support of increased earnings response coefficient with increased sustainability performance.Research limitations/implicationsThis study adds to the literature supporting the notion of sustainability investing indicating that sustainability performance of a firm affects the stock price informativeness and predictability of earnings (changes) of the firm.Originality/valueThis study has value for, both, investors and managers regarding the importance of sustainability performance of the firm. Sustainability performance of the firm sends signals to market participants, increasing the informational content of the reported earnings as well as predictability of future earnings.","PeriodicalId":44116,"journal":{"name":"American Journal of Business","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77399481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theory and empirics provide support for the idea that a good corporate reputation improves firm value, but much of the previous research fails to consider the risk of the companies they study and relies only on accounting measures of performance such as return on assets. A complete picture of the relationship between corporate reputation and shareholder value should include risk-adjusted returns and correlation with benchmark returns.Design/methodology/approachThe Harris Poll Reputation Quotient (RQ), based on the reputations of the 100 most visible companies, suggests that companies with a “solid reputation” are more likely to be attractive investments. The authors construct portfolios using deciles and the RQ categories, rebalancing annually as RQ rankings are updated. Returns are adjusted for risk using Jensen's alpha, the information ratio, the Sharpe ratio, Modigliani and Modigliani's M2 measure, and Muralidhar's M3 measure.FindingsThe results indicate that choosing a portfolio based on the highest RQ-ranked firms does outperform the market on a risk-adjusted basis, and that the relationship between rankings and time-weighted returns is roughly monotonic. The authors also observe that corporate reputation is persistent, and that the best and worst most-visible firms are more likely to be privately held.Originality/valueThis research adds to the literature by including both market-based return measures and risk in the examination of the relationship between corporate reputation and financial performance.","PeriodicalId":44116,"journal":{"name":"American Journal of Business","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85681708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach is to strategically manage, monitor and assess stakeholders' involvement efficiently during the various stages of the project. The paper aims to structure and organize the stakeholder management ecosystem concept, which would enhance working standards by gaining support and healthy interest of stakeholders in the ever-changing and increasing complex business environment.Design/methodology/approachA theoretical framework study is incorporated on the secondary data of stakeholder management, engagement and assessment. The conceptual insights are drawn for the comprehensive framework of 4Ps (project, people, process and promoting participation) to establish a stakeholder management ecosystem.FindingsThe findings expand the understanding and importance of efficient stakeholder management practices through a stakeholder management ecosystem concept. The implementation of efficient practices can exert a significant effect on the project outcome and organizational goals. Thus, these practices should be assessed and altered according to changing situations and dynamics at the various stages of the project.Practical implicationsThe paper contributes to the literature on stakeholder management. First, it holds organizational and managerial implications to efficiently channelize stakeholder resources to maximize the output of the project and the performance of an organization. Second, managing people associated with an organization formally or informally can not only draw their interest, trust and involvement but also can develop further scope and vision of growth and development.Social implicationsThe philosophy behind the concept is social cooperation and value creation. The more the people are engaged with the organization, the more will be the organizational support and well-being in the community as it broadens the pool of people involved, both inside and outside the organization.Originality/valueThe paper advances the practices of stakeholder management and organization management by introducing the ecosystem concept, 4Ps framework and assessment matrix. The ecosystem concept can be used to develop value and explore the potential of each person associated with an organization and further develop a functional relationship. The 4Ps framework is a structured and flexible approach to ease the process of understanding, analyzing, evaluating and involving stakeholders. The assessment matrix supports the evaluation of the incorporated strategy and further decision-making for the project by gauging project performance and stakeholder involvement.","PeriodicalId":44116,"journal":{"name":"American Journal of Business","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74538073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Supported by three different case studies, the research focuses on the different factors that affect crowdsourcing for open innovation. Moreover, the findings give us a proposed managerial framework to be considered when adopting crowdsourcing in addition to factors that proved its huge effect on crowdsourcing activities.Design/methodology/approachA qualitative research approach for this research was the most convenient. It focuses on providing an in-depth understanding of the phenomena. Qualitative research represents the views and perspectives of the participants in a study besides it is driven by a desire to explain these events, through existing or emerging concepts (Yin, 2016). Adopting a case study research method that investigates a contemporary phenomenon (the “case”) in depth and within its real-world context, especially when the boundaries between phenomenon and context may not be evident (Yin, 2018) as in crowdsourcing based business model for open innovation.FindingsThe researchers presented the benefits and challenges when considering crowdsourcing establishing a managerial framework for open innovation. Additionally, the researchers identified the different factors that highly affect crowdsourcing proposing a model that can be used for adopting crowdsourcing. The research also presented insights about how crowdsourcing was introduced in the Egyptian market and how it evolved through the years.Research limitations/implicationsThe study had some limitations to be considered in the following work. Company X used crowdsourcing within a high degree of limitations and confidentially consequently, restricting the effects and results of crowdsourcing. Another limitation was that the study has been only qualitative, and the addition of the quantitative approach will numerically support the findings. Moreover, the research depended on the businesses only as of the source of information and neglected the crowd sample.Practical implicationsThe main aim of this study was to address the lack of research evidence on what it means to adopt crowdsourcing for open innovation in Egyptian firms. The authors have done so by adopting three case studies which enabled them to directly observe and report on the daily work of trust CEOs, with special attention to the practices. Whereby, these executives made themselves knowledgeable for all practical purposes, as dictated by their specific job. Accordingly, the first major contribution of the present research is that it provides much-needed empirical data on the actual practices of crowdsourcing in three Egyptian, yet international companies. Moreover, the results could be used as a guideline when considering crowdsourcing activities highlighting the advantages and disadvantages of such activities.Originality/valueThe paper discusses different perspectives of crowdsourcing pres","PeriodicalId":44116,"journal":{"name":"American Journal of Business","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81193663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
