How Subgroup Interests and Reputations Moderate the Effect of Organizational Identification on Cooperation

Two experiments tested the effects of organizational identification on individual decisions to cooperate. These decisions occurred in the context of a nested social dilemma in which individuals, subgroups, and the larger collective each held distinct and incompatible interests. In Study 1, when the two subgroups in the dilemma were from different real organizations, higher organizational identification caused lower cooperation with the collective (and higher cooperation with the subgroup) when the opposing organization had a purportedly individualistic culture and reputation. The results of Study 2 supported this interpretation by showing that organizational identification had a negative effect on collective cooperation, and a corresponding positive effect on subgroup cooperation, when decision makers perceived the opposing department to have an individualistic reputation. I discuss the implications of these results for organizations that try to elicit cooperation by fostering members’ organizational identification.     

Relationship between Online Retailers’ Reputation and Product Returns

Customer product returns are key cost drivers that eat into online retailers’ profits. However, management research has neglected to examine ways of reducing return rates without causing a concomitant decrease in sales. Drawing from signalling and dissonance theories, we investigate the relationship between online retailers’ reputation and product return rates. Two experiments designed to produce causal conclusions show that reputation reduces return rates (Studies 1 and 2) and that return motivation is a boundary condition for that relationship (Study 2). A field study based on an online consumer panel demonstrates the robustness of the negative impact of online retailer reputation on product returns in a setting that emphasizes external validity (Study 3), in comparison with Studies 1 and 2, which maximize internal validity. Study 3 also examines managerially important contingencies of the causal relationship by considering three variables: purchase frequency; retailer type; and customer gender. Overall findings indicate that an online retailer's reputation is a powerful means of reducing product return rates. The findings also show that the strength of the relationship between reputation and product returns is influenced by return motivation and the three variables investigated in the field study.     

Value of Information in Closed Loop Supply Chains

We explore the value of information (VOI) in the context of a firm that faces uncertainty with respect to demand, product return, and product recovery (yield). The operational decision of interest in matching supply with demand is the quantity of new product to order. Our objective is to evaluate the VOI from reducing one or more types of uncertainties, where value is measured by the reduction in total expected holding and shortage costs. We start with a single period model with normally distributed demands and returns, and restrict the analysis to the value of full information (VOFI) on one or more types of uncertainty. We develop estimators that are predictive of the value and sensitivity of (combinations of) different information types. We find that there is no dominance in value amongst the different types of information, and that there is an additional pay‐off from investing in more than one type. We then extend our analysis to the multi‐period case, where returns in a period are correlated with demands in the previous period, and study the value of partial information (VOPI) as well as full information. We demonstrate that our results from the single period model (adapted for VOPI) carry‐over exactly. Furthermore, a comparison with uniformly distributed demand and return show that these results are robust with respect to distributional assumptions.

The Primary Importance of Corporate Social Responsibility and Ethicality in Corporate Reputation: An Empirical Study

We examine three assumptions commonly held in the corporate reputation literature: (1) reputation ratings of owners and investors are generally representative of all stakeholders; (2) stakeholders will generally provide a higher reputation rating to firms that emphasize corporate social responsibility versus firms that do not; and (3) profitability is the primary criterion of importance to all stakeholders when rating a firm's reputation. Using an exploratory in‐class exercise, our findings suggest that: (1) there are significant differences among stakeholder groups in their reputation ratings; (2) firms that emphasize corporate social responsibility are not rated more highly across all stakeholder groups; and (3) for all stakeholder groups, the ethicality criterion explained more of the variance in firms' reputation ratings than the profitability criterion.

From competency to conversation: A multi-perspective approach to collective leadership development

Collective leadership involves the participation of multiple entities in the leadership process. This body of research is informed by a variety of theoretical perspectives, including person-centered, social network, social-relational, sociomaterial, and institutional views. Despite multiple calls for leadership development to move beyond individual leadership, collective leadership development remains focused on coaching and competency development, extending rather than reconsidering the person-centered perspective. We argue that it is necessary and timely to align the practice-based literature on leadership development with theoretical and empirically-based perspectives on collective leadership. We provide a multi-perspective framework of collective leadership development by 1) introducing a wider disciplinary range of theoretical perspectives on collective leadership development; 2) integrating these perspectives with leadership development approaches for different forms of collective leadership; 3) illustrating how the multiple perspectives on collective leadership development can be applied to specific work contexts; and 4) identifying directions for future research.     

Building Reputations: The Role of Alliances in the European Business School Scene

How should businesses best choose foreign partners as they seek to internationalise? We use reputation theory to examine this question. Building reputation is a key aim on the European Business School scene, and this article starts by using more than 2,000 articles written by European academics in top quality journals to update the LRP research reputation rankings of European Schools. We then look at the way international research collaboration takes place, and find that alliances between schools are far from random. It seems that academics from US and European schools are strongly attracted to form alliances with one another, and the choice process appears to be consistent with reputation theory that suggests US schools seek out the most reputable foreign partners. Moreover, the “charmed circle” of high-reputation partners appears to be defined on a country-to-country basis rather than from a whole-Europe perspective. The lessons for managers in internationalising industries are that international alliance choice must include a reputation perspective, with great care being paid to the exact nature of the foreign partner's achievements.     

An approach to consensus measurement of linguistic preference relations in multi-attribute group decision making and application

This paper studies the group decision making problem with linguistic preference relations. We first study the consensus measure between the individual preference relations and the collective (group) preference relation by defining the concept of degree of similarity between two linguistic values and two linguistic preference relations. Then we propose a concept of the acceptance consensus threshold value for group decision making with linguistic preference information. We show that the consensus between individual preference relations and the collective (group) preference relation is greater than the weighted similarity degree of a given individual preference relation with respect to other individual preference relations in group decision making with linguistic preference relations. The results will help in the analysis of crucial issues of conflict and agreement among preferences of decision-makers, which affect the consensus of group decision making with linguistic preference relations. Theoretical foundations are then established for the proposed method. Finally, the proposed method is applied to evaluate the degree of consensus of individual overall preference values with respect to the collective overall preference values for multi-attribute group decision making with linguistic information. The main contribution of this paper is twofold. One is to present a new way to measure the consensus between the individual preference relations and the collective (group) preference relation in group decision making with linguistic preference information. Another is to provide an effective approach to evaluating individual overall preference values with respect to the collective overall preference values in multi-attribute group decision making with linguistic information.     

On self-interest and greed

First the assumption of self-interest as applied in Economics is presented. Here we also discuss areas in which (many) people behave less self- but more other-regarding than traditional economic models assume. Then, greedy behaviour is considered as existing in the political and economic ‘world’. Here we refer to corruption as well as to the role of money as a positional good. We also discuss such behaviour in the academic world, in which money plays a role as well as reputation. Thus, while the assumption of mutually disinterested rationality is a very powerful instrument for analysing individual behaviour, to explain some phenomena we have to recognise that people are not only sometimes other-regarding, but also sometimes greedy, and that they might value money much more than traditional Economics assumes. We conclude with some remarks on what we can learn in this respect from Behavioural Economics.     

基于声誉及信息操纵考虑的基金经理持股策略演化博弈研究

基金经理运用声誉及信息操纵来获得超额利润的现象频发已严重阻碍了中国证券市场的健康发展,因此明晰其中的博弈演化机理以减少基金经理道德风险的发生具有较高的研究价值。本文通过数理模型从声誉及信息操纵两个维度研究了基金经理持股策略演化博弈过程。研究发现,如果非明星基金经理树立声誉的净收益大于市场平均收益,那么经过长期演化博弈,具有有限理性的明星基金经理选择继续维护声誉策略,非明星基金经理选择建立声誉策略。当强势明星基金经理信息操纵的收益小于信息操纵的成本时,无论外部投资者是否监督,有限理性的强势明星基金经理均会选择如实披露信息的策略。当外部投资者监督的收益小于监督的成本时,外部投资者选择不监督策略;当外部投资者监督的收益大于监督的成本时,外部投资者的策略选择依赖于强势明星基金经理的策略选择,强势明星基金经理选择信息操纵策略的概率越大,外部投资者越可能选择监督策略。     

个体与机构投资者,谁左右A股股价变化?——基于投资者异质信念的视角

在成熟的资本市场,机构投资者一直都被视作资产定价的主体。但在个体投资者众多的中国证券市场,个体投资者与机构投资者谁左右A股股价的变化?则是人们关注的热点话题。本文从投资者异质信念的视角,构建个体投资者与机构投资者未预期交易量两个异质信念测度指标,对比分析二者与股票收益的相关性。结果表明,个体投资者与机构投资者的异质信念与股票当期收益显著正相关、与未来一期收益显著负相关,但个体投资者异质信念的作用更强;进一步,异质信念对小公司、价值型公司收益的影响更明显;当控制了规模、价值等风险因子,以及不同时间区间和是否可以卖空等市场影响因素后,结论依然成立。表明在现阶段的中国A股市场,个体投资者的异质信念仍是左右股票定价的主要因素。     

Exploring the Impact of Social Axioms on Firm Reputation: A Stakeholder Perspective

This study proposes a model of how deeply held beliefs, known as ‘social axioms, moderate the interaction between reputation, its causes and consequences with stakeholders. It contributes to the stakeholder relational field of reputation theory by explaining why the same organizational stimuli lead to different individual stakeholder responses. The study provides a shift in reputation research from organizational‐level stimuli as the root causes of stakeholder responses to exploring the interaction between individual beliefs and organizational stimuli in determining reputational consequences. Building on a conceptual model that incorporates product/service quality and social responsibility as key reputational dimensions, the authors test empirically for moderating influences, in the form of social axioms, between reputation‐related antecedents and consequences, using component‐based structural equation modelling (n = 204). In several model paths, significant differences are found between responses of individuals identified as either high or low on social cynicism, fate control and religiosity. The results suggest that stakeholder responses to reputation‐related stimuli can be systematically predicted as a function of the interactions between the deeply held beliefs of individuals and these stimuli. The authors offer recommendations on how strategic reputation management can be approached within and across stakeholder groups at a time when firms grapple with effective management of diverse stakeholder expectations.     

Trading on Twitter: Using Social Media Sentiment to Predict Stock Returns

Decision making is often based on the rational assessment of information, but recent research shows that emotional sentiment also plays an important role, especially for investment decision making. Emotional sentiment about a firm's stock that spreads rapidly through social media is more likely to be incorporated quickly into stock prices (e.g., on the same trading day it was expressed), while sentiment that spreads slowly takes longer to be incorporated into stock prices and thus is more likely to predict stock prices on future days. We analyzed the cumulative sentiment (positive and negative) in 2.5 million Twitter postings about individual S&P 500 firms and compared this to the stock returns of those firms. Our results show that the sentiment in tweets about a specific firm from users with less than 171 followers (the median in our sample) had a significant impact on the stock's returns on the next trading day, the next 10 days, and the next 20 days. Interestingly, sentiment in tweets from users with fewer than 171 followers that were not retweeted had the greatest impact on future stock returns. A trading strategy based on these findings produced meaningful economic gains on the order of an 11–15% annual return.     

Corporate reputation: Meaning and measurement

Corporate reputation has attracted interest from a wide range of academic disciplines. It is also a growing focus for business and media attention. This paper examines the construct of corporate reputation, first by untangling the terminological problems that have been caused by the interdisciplinary nature of much of the earlier work in the area. The construct of reputation and the allied constructs of image and identity are each reviewed. A structure is proposed in which the three constructs can be seen as labelling different but allied concepts. I then move on to consider how reputation has been measured. The paper uncovers considerable confusion in the use of what might appear to be basic terms and links this to a subsequent lack of grounded measurement tools in the sector, until relatively recently. With a clearer understanding of the construct of corporate reputation and the allied constructs of image and identity, researchers are now well placed to test the relationships widely claimed by practitioners between corporate reputation and other variables such as commercial performance and employee and customer satisfaction. The review ends by illustrating some of the issues that can be assessed from the basis of a clearer conceptualization of reputation and its measurement.     

Social Identification and Corporate Irresponsibility: A Model of Stakeholder Punitive Intentions

Scholars hypothesize that retaliations against corporate social irresponsibility (CSI) are more likely when observers share the social identity of the victims. We present a model that explains in‐group bias against irresponsibility and identify collective narcissism as a moderator of this effect. Experiment 1 demonstrates that the effect of identity on retaliations is mediated by the perceived similarity of the victims which reinforces feelings of sympathy towards the victims and anger towards the corporation. These emotions drive stakeholders’ attitudes and retaliations. Our study shows that appraisals of the victims of CSI are an important antecedent of stakeholders’ emotions and behavioural intentions. Our evidence also demonstrates that sympathy, an emotion neglected by past research in this area, has a unique effect on individuals’ reactions. Experiment 2 demonstrates that social identity biases in individual punitive intentions are moderated by individuals’ level of collective narcissism. Collective narcissists see out‐group victims as very dissimilar from the self, whereas individuals with low levels of collective narcissism do not differentiate between victims of CSI on the basis of their identity. We extend knowledge on stakeholders’ reactions to CSI and offer insights to organizations promoting campaigns against irresponsible behaviour or managing the fallout from cases of corporate irresponsibility.

Does a firm’s exposure to ethical failures matter to financial markets? A governance perspective

This paper investigates if a firm’s ethical reputation, in conjunction with its governance, affects its standing within financial markets. A firm`s ethical reputation, as measured by ethical failures, arises from its involvement in ethical violations and incidents while a comprehensive index proxies for governance. We assess a firm’s standing within financial markets through two complementary perspectives, i.e., the level of information asymmetry between managers and investors, as inferred from analyst forecast dispersion and analyst forecast error, and the relation between a firm’s earnings and its stock market valuation or return (value relevance). Our results suggest that a firm`s ethical reputation affects financial analysts’ forecasts as well as the stock market value assigned to its reported earnings. Moreover, it appears that corporate governance moderates such relations, with strong (weak) governance compensating for a weak (strong) ethical reputation. Overall, our evidence shows that ethical failures do not seem to pay.     

基于“Meta分析”视角的企业社会绩效与企业财务绩效之间的关系研究

随着企业社会责任理论体系逐步的发展与完善,国内外学者开始关注企业社会绩效(CSP)与企业财务绩效(CFP)之间的关系,但是其中大量有关的研究结果却是互相矛盾的。本研究首先提出了一个理论模型以及相关研究假设,以国内外有关的实证研究文献作为研究对象,采用Meta分析方法对各项独立研究结果进行综合统计分析。其研究结果表明:企业社会绩效常常与企业财务绩效是直接地相互作用和相互影响的;企业管理能力和企业声誉作为中介变量对CSP与CFP关系有着正向的影响,其中企业声誉有着高度的影响;大多数CSP测量方法与CFP测量方法之间有着显著的正向关系,其中CSP声誉排名测量方法与CFP测量方法之间显示出相当高的正向关系,而以市场基础和会计基础CFP测量方法与CSP测量方法之间的关系要低于感知(调查)CFP测量方法的。最后,将其研究结果与相关文献的研究结果进行了比较,并提出了研究结论和相关启示。     

A Matter of Reputation and Pride: Associations between Perceived External Reputation,Pride in Membership,Job Satisfaction and Turnover Intentions

This study investigates how job satisfaction and turnover intentions are related to external reputation as perceived by employees and their pride in membership. Based on a cross‐sectional survey including 439 employees, it also provides insights into external reputation as a possible source of collective pride. Study results indicate that, in agreement with social identity theory, outsiders' views of the organization are closely associated with employees' pride in organizational membership as well as job satisfaction. Both pride and job satisfaction mediate the relationship between perceived external reputation and turnover intentions. Hence, a favourable reputation matters in managing turnover intentions and is closely related to employee pride and satisfaction. Tenure of employees is positively associated with pride while intensive customer contact is negatively related to perceived external reputation and pride. Implications pinpoint the need for alignment of reputation management and human resources management. Furthermore, managers need to focus on new staff and employees with frequent customer contact and should implement pride‐building strategies according to the tenure of employees and intensity of customer contact.
