Abstract
Purpose
As the application of crowdsourcing contests grows, leveraging the participation of superstars (i.e. solvers who have outstanding performance records in a crowdsourcing platform) becomes an emergent approach for managers to solve crowdsourced problems. Although much is known about superstars’ performance implications, it remains unclear whether and how their participation affects the size of a contest crowd for a crowdsourcing contest. Based on social contagion theory, this paper aims to examine the impact of superstars’ participation on the crowd size and studies how this impact varies across solvers with different heterogeneity in terms of skills, exposure and cultural proximity with superstars in crowdsourcing contests.
Design/methodology/approach
This paper uses secondary data from one crowdsourcing platform that includes 6,587 innovation contests to examine superstars’ main and contextual effects on the crowd size of a contest.
Findings
Our results reveal that superstars’ participation positively affects the crowd size of a contest in general. This finding suggests that social contagion is a fundamental mechanism underlying crowd formation in crowdsourcing contests. Our results also indicate that in contests that involve multiple superstars, superstars’ effect on crowd size becomes negative when we simultaneously consider other solvers’ heterogeneity in terms of skills, exposure and cultural background, and this negative effect will be intensified by increases in the skill gap, extent of exposure and cultural proximity between superstars and other solvers in the same contest.
Originality/value
Our research enhances the understanding of the influence of superstars and the mechanism underlying the emergence of contest crowds in crowdsourcing contests and contributes knowledge to better understand social contagion in a competitive setting. The results are meaningful for sourcing managers and platform supervisors to design contests and supervise crowd size in crowdsourcing contests.

Abstract
Superstars, or prominent managers who are responsible for strategic external relationships, are a resource for domestic firms and multinational corporations (MNCs). Theory suggests that MNCs employ superstars to manage organizational legitimacy and offer greater compensation and promotion potential. Domestic firms may employ superstars to enhance their organizational identity and offer them status and a supportive organizational environment. Empirical analysis of 411 advertising agencies in the U.S. and 239 superstars in advertising suggests that domestic agencies have a slight but statistically significant advantage in attracting and retaining superstars relative to MNCs. The strategic implications for domestic firms and MNCs are discussed.

Abstract
Purpose
The purpose of this paper is to examine the effect of superstars (and other factors) on football fans’ attraction to competition (i.e. disloyal behavior).
Design/methodology/approach
A proprietary data set including archival data on professional German football players and clubs as well as survey data of more than 900 football fans is used. The hypotheses are tested with two-sample mean-comparison t-tests and multivariate probit models.
Findings
This study provides evidence that superstars both attract new fans and contribute to the retention of existing fans. While the presence of superstars, team loyalty and team identification prevent football fans from being attracted to competition, the team's recent performance seems to have no effect. Fans who select their favorite player from a competing team rather choose superstars, young players, players who are known for exemplary behavior and defenders.
Originality/value
This paper contributes to existing research by expanding the list of antecedents of disloyalty and by being the first to employ independent, quantitative data for the assessment of superstar characteristics in the context of team loyalty.

Abstract
We provide a Bayesian inference for a mixture of two Pareto distributions which is then used to approximate the upper tail of a wage distribution. The model is applied to the data from the CPS Outgoing Rotation Group to analyze the recent structure of top wages in the United States from 1992 through 2009. We find an enormous earnings inequality between the very highest wage earners (the “superstars”), and the other high wage earners. These findings are largely in accordance with the alternative explanations combining the model of superstars and the model of tournaments in hierarchical organization structure. The approach can be used to analyze the recent pay gaps among top executives in large firms so as to exhibit the “superstar” effect.

Abstract
Purpose
The purpose of this paper is to measure the effect of superstar gig workers, defined as independent contractors who are the most successful in their field, on shareholder value. Gig workers comprise as much as 33% of the workforce and are projected to exceed 50% by 2028. Thus, understanding their impact on shareholder value is important.
Design/methodology/approach
This paper uses OLS regression analysis. To establish causality regarding wealth effects, the sudden deaths of superstar gig workers are used. To facilitate the uncontaminated measurement of wealth effects, sudden deaths that coincide with a significant event on a [−3, 3] window about the death event are not used.
Findings
The sudden death of a superstar gig worker causes shareholder wealth to increase significantly by 0.35% or almost $1.5m. Rational and behavioral explanations are offered for this result.
Research limitations/implications
Generalizability is limited because data on superstar gig workers in traditional corporations are unavailable. For this reason, this paper uses the only available data, namely, data on superstar wrestlers, who are contracted to perform in matches (i.e. “gigs”) in a lucrative promotion (e.g. World Wrestling Entertainment (WWE)). Future research could examine the effect of corporate gig workers on shareholder value if the data become available at some point.
Originality/value
This paper is the first to document the effects of any type of gig worker, whether superstar or regular, on shareholder value.

The paper seeks to test empirically a variety of hypotheses related to human capital and organizational performance within software companies in Egypt.
Abstract
Purpose
The paper seeks to test empirically a variety of hypotheses related to human capital and organizational performance within software companies in Egypt.
Design/methodology/approach
A valid research instrument was utilized to conduct a survey of 38 software companies who are representative of the 107 members of the Software Industry Chamber of Egypt. A correlation analysis and stepwise regression were conducted to ascertain the validity of the hypotheses.
Findings
Statistical support was found for six of the nine hypotheses tested.
Research limitations/implications
One of the limitations of this study is that human capital metrics were based on CEO self‐reported scores. Thus, the ability to generalize is limited to this context.
Practical implications
Of all the human capital metrics collected, the number of superstar developers seems to be the most critical variable in predicting export intensity. Superstar developers are those individuals whose productivity equals four times that of the other developers and twice that of the star developers.
Originality/value
This paper tests empirically the relationship between human capital and organization performance in the Egyptian software industry context and provides support for the recruitment and development of superstar developers.

Abstract
Outlines previous research on the security analyst “superstar” phenomenon, including the stochastic model of Yule and Simon. Applies this to data on the 1986‐1997 selections for the Institutional Investor’s All‐British Research First Team (ABRT) and finds that it does not explain the distribution, i.e. that selection does appear to be based on skill rather than luck. Considers consistency with other research and expects future research to concentrate on the ABRT’s ability to forecast earnings per share and share prices.

Abstract
This chapter critically discusses the many positive aspects that are ascribed to gazelle firms by exploring the external effects and dark sides of high firm growth. On the background of the more general debate on purpose versus profit as a firm’s mission, the chapter theoretically elaborates on the dichotomy between quantitative and qualitative growth of gazelles. This is followed by a case-based illustration and exploration as to how quantitative and qualitative growth interrelates in gazelles and what are impediments for high growth that is purpose driven. The chapter closes with a discussion of the Janus-faced nature of gazelles and how their corporate citizenship can be enhanced.

Abstract
Purpose
Studies that examine users’ perceptions of museum’s website quality are scarce. The purpouse of this paper is to propose a multi-group comparison between two superstar museums to outline the variables that define website quality regarding museum websites towards achieving e-loyalty, trust and perceived control.
Design/methodology/approach
The sample comprised 305 valid online questionnaires, collected from a panel survey using a quota-sampling technique. The proposed model was tested using partial least squares analysis multi-group comparison between Prado and Thyssen-Bornemisza museum websites.
Findings
Website quality plays a determinant role in users’ behavioural outcomes. As evidenced in the results for the first time in a museum setting, website quality has the potential of influencing e-loyalty, trust and perceived control. Besides, trust has a positive influence on e-loyalty and perceived control, on trust. The multi-group comparison revealed no significant differences between the two museum superstars, which offer highly useful insights for the correct design of these websites.
Originality/value
This research addresses a multi-group comparison using partial least squares, a quite recent technique that advances knowledge regarding this method. It contributes to knowledge museum website management and online literature by means of proposing website quality as a dimension that includes content, ease of understanding, emotion, informational fit-to-task, promotion and visual appeal and by revealing significant effects of the relationships of the proposed model. Museum managers are provided with valuable inputs to design websites in an appropriate and suitable way for their users so they will be more willing to repeat their navigation experience.

Abstract
Purpose
Mentoring larger numbers of people can be a challenge. This paper seeks to show how performance support can overcome scalability barriers and cost‐effectively provide best practice and up to date help to people throughout an organization, and internationally, on a 24/7 basis and wherever and whenever they need assistance.
Design/methodology/approach
Performance support tools can capture and share what high performers do differently in areas in which they excel, and enable others to emulate their approaches to understanding complex situations and doing difficult tasks. The author presents drawbacks of traditional mentoring and training, and summarizes the return on investment, scalability, flexibility, and sustainability advantages of performance support.
Findings
Tools examined have yielded multiple benefits to users and commissioning organizations. Relevant and current support can be provided as and when help is needed, including out of the office and on the move.
Practical implications
Performance support has generated high returns on investment. Results include better understanding, higher productivity, quicker and bespoke responses, reduced costs, less stress, and evidenced compliance. Support and learning occurs at the place and time of work. Users can benefit from the advice of whoever has the most relevant and highly effective way of addressing whatever problems arise at each stage of a task.
Originality/value
Research underpinning performance support is summarized, and what it is and its implications are described. It is compared with e‐learning and face‐to‐face approaches. Performance support can complement, supplement or replace traditional approaches to mentoring and training, making superstar support available to larger numbers of people, as and when assistance is required.
