This paper aims to examine the impact of individual and group-level variables on knowledge exchange and identification in age diverse teams. From a diversity perspective, influences of age-related diversity perceptions and diversity beliefs (level 1) are compared with effects of objective age diversity (level 2). From a management perspective, the paper goes beyond age diversity and investigates the incremental effects of team and individual characteristics from a team learning perspective.

Questionnaire data of 516 team members and their supervisors in 73 organizational teams were analyzed in a multilevel approach.

Objective age diversity had a negative effect on knowledge exchange and identification. Beyond that, age-related diversity perceptions and positive diversity beliefs on the individual level predict the effect of objective diversity. Relativizing the impact of diversity, individual characteristics (knowing the team experts, clear understanding of goals) and team characteristics (team climate, time for knowledge exchange) explain the largest proportion of variance in the dependent variables underlining the importance of team learning variables.

Compared to objective diversity, subjective diversity perceptions and diversity beliefs are relevant predictors of processes and attitudes in heterogenic teams.

There are multiple leverages for management strategies beyond the mostly fixed age diversity in teams on the individual and group level.

This paper evaluates the cross-level interplay between objective diversity, perceived subjective diversity and diversity beliefs and revalues the impact of HR-management in age diverse teams.

The purpose of this paper is to examine the extent to which negative age-based metastereotypes mediate the relationship between the representation of older workers and two forms of stereotype threat in the workplace: own-reputation and group-reputation. Adopting a social identity perspective, this paper also explores whether age diversity beliefs moderate the relationship between negative age-based metastereotypes and stereotype threats.

A cross-sectional design was adopted with bootstrapped mediation and moderation analyses. The data were collected from 567 older workers working in 15 manufacturing companies.

The analyses provide support for partial mediation and for a moderation effect of age diversity beliefs in the relationship between negative age-based metastereotypes and own-reputation threat. The results hold while controlling for age, objective organizational age diversity, and organizational tenure.

The limitations of this study include its cross-sectional nature and the need for further work regarding older workers’ metastereotypes about middle-aged workers.

For stereotype threat interventions to be effective they must identify beforehand the target and the source of the threat. Moreover, interventions should aim for the development of a sense of identity on the organization as it may pave the way for members of different age groups to build bonds and for intergenerational boundaries to be blurred.

This paper contributes to the literature by showing the importance of negative age-based metastereotypes in workplace age dynamics. It also provides further support for a multi-threat approach to the experience of age-based stereotype threats in the workplace.

The age diversity climate construct is gaining greater attention in the organizational literature due to the demographic changes in the workplace. While the few existing studies on age diversity climate (ADC) are rather encouraging, this construct is still at an early stage of conceptual and operational development. This chapter helps to advance this field of research by analyzing the conceptual issues stemming from the theoretical definition and empirical measurement of the ADC construct. We first review and compare ADC with other age-focused climate concepts, highlighting overlapping and diverging factors regarding their conceptual framework and operationalization. Subsequently, we consider several open issues related to the operationalization of ADC, including the level of analysis, the choice of referent, and the dimensions of analysis. We conclude the chapter by outlining possibilities for future research on ADC.

Important demographic changes are causing organizations and teams to become increasingly age-diverse. Because knowledge sharing is critical to organizations’ long-term sustainability and success, both researchers and practitioners face a strategic dilemma: namely, finding ways to cultivate greater knowledge sharing among different age cohorts.

In this chapter, we claim that age diversity adds relevant opportunities and distinct challenges. On one hand, it increases demands for effective knowledge sharing: Employees of different ages are likely to hold diverse knowledge and capabilities that may be lost and/or poorly exploited if they are not effectively shared. On the other hand, age differences can activate age-related stereotypes and foster the formation of age subgroups, which can hamper social integration, communication, and ultimately, knowledge sharing.

Building on these insights, this chapter looks at the role of the human resource management (HRM) system as a key facilitator of effective knowledge sharing in age-diverse organizations. To this end, the chapter focuses on HR planning, training and development, performance appraisal, and reward systems, each of which can be used to develop the motivations, norms, and accountability structures that encourage employees of different ages to bridge their differences and integrate their unique perspectives and knowledge. This chapter suggests ways of tailoring HRM practices to unlock the benefits of age diversity, which may help organizations exploit and capitalize on the knowledge-based resources held by their younger and older employees.

This paper investigates the interaction effects of gender diversity and diversity beliefs on group-level personality fit (“collective personality fit”) and group organizational citizenship behavior (GOCB). It seeks to provide a sufficient understanding of the under-researched area, such as how group composition impacts group behavioral outcomes.

Data were collected from 453 employees and their leaders in 63 teams of Korean private sector firms using a moderated-mediation model.

This study found that high diversity beliefs can weaken the negative effects of gender diversity on collective personality fit and further enhance GOCB. The results confirm the moderated-mediation effect of diversity beliefs in the relationship between gender diversity and GOCB.

Management should realize that the negative effect of workforce diversity on GOCB can be reduced by boosting collective personality fit in the team. In this process, enhancing diversity beliefs may relieve the adverse effects on GOCB caused by workgroup gender differences.

This study develops a group-level model proposing that the interaction effects of gender diversity and high diversity beliefs enable a high level of collective personality fit, enhancing GOCB. It attempts to investigate the effects of gender diversity at the group level under boundary conditions.

The global nature of today’s business environment, coupled with technological advances, has resulted in leaders working with an increasingly diverse workforce worldwide. An emerging stream of research examines the beliefs that individuals, groups, and organizations have regarding diversity. The purpose of this paper is to add to this work by looking at subordinate perceptions of a leader’s beliefs about diversity and how that relates to a leader’s performance.

Using archival data, the authors examine 33,976 leaders (from 36 different countries and more than 4,000 companies). This study includes performance ratings from each leader’s supervisor as well as perceptual measures of diversity beliefs from their direct reports and a measure of national culture as a moderator.

The research finds that employee perceptions of a leader’s diversity beliefs are related to supervisor ratings of the target leader’s performance. In addition, the relationship between a leader’s diversity beliefs and the target leader’s performance rating is stronger in cultures high in performance orientation (PO) than in cultures low in PO.

The limitations include the use of an archival data set as well as an assigned country score for our measure of culture.

While existing research has examined the impact of self-rated measures of diversity beliefs, there is little empirical research that examines how employee perceptions of a leader’s diversity beliefs will impact performance. The authors address this need by examining whether employee-rated perceptions of the leader’s diversity beliefs are related to a supervisor-rated measure of leader performance. In addition, the authors examine the moderating influence of societal culture on this relationship.

Due to demographic changes in most industrialized countries, the average age of working people is continuously increasing, and the workforce is becoming more age-diverse. This review, together with the earlier JMP Special Issue “Facilitating age diversity in organizations – part I: challenging popular misbeliefs”, aims to summarize new empirical research on age diversity in organizations, and on potential ways to support beneficial effects of age diversity in teams and organizations. The second part of the Special Issue focusses on managing mutual perceptions and interactions between different age groups.

A literature review is provided summarizing and discussing relevant empirical research on managing mutual perceptions and interactions between different age groups at work.

The summarized research revealed a number of challenges to benefit from age diversity in organizations, such as in-group favoritism, age norms about appropriate behavior of older workers, intentional and unintentional age discrimination, differences in communication styles, and difference in attitudes towards age diversity. At the same time, managerial strategies to address these challenges are developed.

Together with the first part of this Special Issue, this is one of the first reviews on ways to address the increasing age diversity in work organizations based on sound empirical research.

The article applies upper echelon theory to explain variation in parent firms’ post-acquisition financial performance. We develop and test a latent variable model hypothesizing that top management team (TMT) demographic diversity affects financial outcomes through teams’ collective beliefs. In so doing we identify three constructs which potentially underlie classic TMT demographic diversity measures. Also, we propose two fundamental structural properties of team beliefs extrapolated from individual level cognitive complexity theory. Results show both positive and negative effects on financial outcomes from the TMT demographic diversity constructs through the belief constructs. We discuss the importance of including mediating constructs when attempting to unravel TMT diversity’s effects on firm level outcomes.
