Prior studies have consistently shown that leader psychological capital is beneficial for leader–member exchange (LMX) and followers’ outcomes. In this study, the authors challenge this consensus; they propose that a leader with high-level psychological capital may decrease LMX and promote followers’ turnover intention when encountering a follower with low-level psychological capital. Only congruent psychological capital in leader–follower dyads increases LMX and decreases turnover intention.

A two-wave survey was designed to collect data from a sample of 207 leader–follower dyads in the service industries of China. Polynomial regression combined with the response surface analysis was used to test the hypotheses.

(1) LMX increased when the levels of psychological capital between leaders and followers were congruent, but LMX suffered when they were not congruent (e.g. leaders’ psychological capital was higher than followers’ or otherwise); (2) in the conditions of psychological capital congruence, LMX was higher when a leader’s and a follower’s psychological capital were both high than low; (3) LMX mediated the relationship between psychological capital congruence and followers’ turnover intention.

These findings provide a novel perspective on understanding of the function of psychological capital and its implications for turnover management.

The purpose of this paper is to investigate the relationship between leader psychological capital and employee work engagement. Drawing on conservation of resources theory, the authors hypothesize that leader psychological capital is associated with employee work engagement through employee psychological capital. The authors further hypothesize that team collectivism moderates the relationship between leader psychological capital and employee psychological capital.

Multi-source data came from 44 team leaders and 307 employees in Mainland China.

The results suggest a trickle-down relationship between leader psychological capital and employee psychological capital, which in turn is linked to employee engagement. In addition, the relationship between leader psychological capital and employee psychological capital is stronger (weaker) when team collectivism is lower (higher).

By paying attention to the psychological capital of both employees and their leaders, organizations can increase employee engagement which is an important work outcome.

Work engagement is important in the workplace because it is related to a variety of employee work and life outcomes. Prior research has examined the antecedents of work engagement, but little is known about the role of leader psychological capital, a positive psychological state, in shaping employee work engagement. This research applied a resource conservation process model of leader positivity on employee engagement that is mediated by employee psychological capital. This study contributes to a better understanding of the theoretical foundation of leader psychological capital.

Recognising the value of positive organisational behaviour at the workplace, this paper aims to provide a major review of the current state of research on positivity, and subsequently proposes new pathways for more theory building relating to important constructs conceptually related to positivity. Following the integration of emerging but disparate research on workplace positivity and related concepts, the paper develops a conceptual framework depicting the relationships amongst authentic leader behaviours, organisational virtuousness, psychological capital, thriving and job performance.

The paper offers a systematic critical review of published studies representing the literature addressing authentic leadership, organisational virtuousness, thriving, psychological capital and job performance. The paper relied on computerised keyword searches in the main business source databases of Emerald, ProQuest, ScienceDirect, EBSCOhost and SpringerLink.

This paper leads to a conceptual framework proposing direct relationships between authentic leadership, psychological capital, organisational virtuousness and job performance. Further, authentic leadership is proposed to potentially nurture organisational virtuousness, psychological capital, employee thriving and job performance, given the theoretical linkages between these conceptually relevant variables related to positivity. Additionally, organisational virtuousness and psychological capital are projected to mediate the relationship between authentic leadership and employee thriving. Finally, organisational virtuousness, psychological capital and employee thriving are designated as mediators of the relationship between authentic leadership and job performance.

This paper proposes a conceptual framework focusing on one form of positive leader behaviour and also assumes specific causal pathways using a positivistic research approach to understanding the leadership–performance relationship. The paper did not examine all possible antecedents of positivity at the workplace.

The proposed conceptual framework should form the basis of many organisational interventions, especially in relation to boosting authentic leadership, organisational virtuousness, psychological capital, employee thriving and job performance. By suggesting the association between authentic leadership, psychological capital and organisational virtuousness, this paper highlights potential benefits from effective leaders’ commitment to enhancing psychological capital and organisational virtuousness and engendering thriving behaviour and job performance.

This novel paper has the potential to stimulate the empirical studies on workplace positivity through the association of authentic leadership, psychological capital, organisational virtuousness and thriving.

Despite the immense amount of literature on ethical leadership and leader‒member exchange (LMX), little is known about how and when ethical leadership and LMX are more/less effective in prompting employee creativity. It is proposed that ethical leadership affects creativity through LMX. Furthermore, the authors draw upon an interactionist perspective and suggest that employee psychological capital is a dispositional boundary condition that influences the effectiveness of LMX in promoting employee creativity. The paper aims to discuss these issues.

Using a survey questionnaire, data were collected from 557 nurses and their supervisors working in public sector hospitals. The data were collected in two phases (time lagged) to avoid common method bias. Moderated mediation analysis was performed, using model 14 of PROCESS, to probe hypothesized relationships.

The results of the moderated mediation suggest that ethical leadership and LMX predict creativity. Ethical leadership indirectly affects creativity through LMX. Employee psychological capital moderates the direct effect of LMX and the indirect effect of ethical leadership on employee creativity.

The study contributes to the extant literature, as the findings suggest that, being a dispositional boundary condition, psychological capital plays a contingent role in explaining LMX and the ethical role of leaders in fostering creativity. Moreover, the results also confirm previous findings, which suggested that ethical leaders promote creativity.

The findings imply that ethical leadership and exchange relationships are important for promoting creativity. Given that creativity is a complex product of an individual’s behavior, high psychological capital employees obtain benefits of quality exchange relationships and utilize them to elicit creativity. Managers are recommended to proactively develop and promote exchange relationships as well as positive psychological resources among employees to achieve creativity.

The study is unique in its scope and contribution, as it tries to develop an understanding of how and when ethical leadership and LMX foster employee creativity. Using an interactionist perspective to theorize psychological capital as a second-stage moderator is, thus, a unique contribution of this study.

The purpose of this paper is to examine the direct and indirect effects of authentic leadership on organizational citizenship behaviour (OCB) with the presence of psychological capital as a mediating factor.

This quantitative research was conducted among 396 front-line employees in six public sector organizations in Sri Lanka. A survey method was employed to collect the data.

It was found that psychological capital partially mediates the relationship between authentic leadership and OCB. In other words, the relationship between authentic leadership and OCB is both direct and indirect, mediated though psychological capital.

The authenticity of leaders' conduct, psychological capabilities and the outcomes of the performance, are rooted in and reinforced by the culture of the particular organization; hence, the findings should be interpreted cautiously.

The framework of the present study provides a guideline to the top management of the public sector in Sri Lanka to design leadership programs that can develop authentic leaders.

The direct and indirect relationships established between authentic leadership and psychological capital and OCB signifies the critical importance of authentic leadership in the development of psychological capital and OCB among employees.

Empirical studies on humility in the area of organizational studies are still scarce, as are studies of humility in leadership. This research aims to contribute to the literature by studying how the humility of leaders predicts the team's creativity through the mediating effect of psychological security and psychological capital.

The sample includes 73 teams and their leaders, from 40 firms operating in different industries. Leaders (n = 73) described their own humility and team creativity. Team members (n = 341) described the leader’s humility, and the team’s psychological safety and psychological capital.

Structural equation modelling (LISREL; maximum likelihood estimation) was used to test the hypothesized model. The findings are represented in Figure 1 (control variables not shown), and the results suggest that the leader’s humility predicts team creativity through team’s psychological safety (PsySafe) and psychological capital (PsyCap).

Main limitations are the small sample size, and the fact that it is a convenience sample, which may limit the generalization of results. One may add the need to conduct longitudinal studies, as well as have a comparison among different regions or countries. These issues are addressed in the study.

This paper contributes to the still limited literature relating humility and leadership. For organizations, if they want to be effective in innovating, they need to understand the influence of the mechanisms that the employees are exposed to and how they influence their creativity. Knowing the positive role of humble leadership in creativity development and employee motivation is particularly interesting for leaders working in the context of creativity, as it is a way of facilitating creativity of employees.

This study aims to empirically examine the relationship of ethical leadership and psychological capital with knowledge creation. It also investigates the effect of psychological capital as a mediator in the relationship between ethical leadership and knowledge creation.

This study is based on quantitative research methodology. The data was gathered using a survey questionnaire from 286 members of public-sector research organizations (PSROs) in India. Structural equation modelling (SEM) was used for hypotheses testing.

The findings of this study show that ethical leadership and psychological capital have a positive influence on knowledge creation. Further, psychological capital mediated the relationship between ethical leadership and knowledge creation.

This study is a quantitative cross-sectional study. However, future researchers may use qualitative research methodology and longitudinal data collection to supplement this study.

This study provides new understanding into the creation of knowledge by emphasizing on the critical role played by ethical leadership and psychological capital and, thus, makes significant theoretical contribution. It emphasizes that managers should not only be ethical but also use interventions to strengthen psychological capital of employees to strengthen knowledge creation.

To the best of authors’ knowledge, this is the first study to examine the underlying mechanism of psychological capital in explaining the links of ethical leadership with knowledge creation.

The purpose of this paper is to explore the effect of affiliative-based humorous leadership on hotel employee outcomes (i.e. resistance to change and upward voice), underpinned by affective events theory. Further, this paper investigates psychological capital as a mediation effect and emotional intelligence as a moderation effect.

Using a structured questionnaire, 554 supervisors of 20 four- and five-star hotels in Sharm El-Sheikh responded based on a time-lagged approach. A Smart-partial least squares (Smart-PLS) v. 3.3.9 was used to analyze the data set.

The findings revealed that affiliative-based humorous leadership has a positive effect on psychological capital, and psychological capital has a positive association with employee upward voice. Psychological capital partially mediated the linkage of humorous leadership with employees' upward voices and resistance to change. According to the results, emotional intelligence strengthened the linkage of psychological capital with employee resistance to change and upward voice.

The findings contribute to the body of knowledge on humor and the development of new ideas in the hospitality literature. This paper adds to the hospitality literature on humorous leadership in developing countries, specifically in Egypt. This paper also provides practitioners with new perspectives as they develop strategies and use humor-related wise leadership styles in the workplace.

To the best of the authors’ knowledge, this paper is one of the first studies to assess affiliative-based humor in leadership in the hospitality industry. This paper contributes to future studies on the crucial effect of workplace engagement and its association with employees’ novel and intriguing actions and offers a good guideline for organizations and enterprises wishing to better leverage leader humor.

This chapter explores the phenomenon of organizational resilience. A comprehensive model was advanced and tested while utilizing a quantitative study conducted in the education system in Israel with 98 schools, involving 1,132 educators. Statistical analysis based on structural equation modeling revealed significant relationships between three antecedents (social capital, team empowerment, goal interdependence) and organizational resilience. In addition, a positive significant relationship was found between organizational resilience and organizational functioning in crisis. Organizational resilience was found to be a mediator between three of the antecedents (social capital, team empowerment, goal interdependence) and organizational functioning in crisis. Furthermore, organizational functioning in crisis was found to mediate the relationship between organizational resilience and organizational innovation. Implications for policymakers, managers, and change leaders in organizations are discussed.

While there is strong agreement that globalization is spreading rapidly, there is no agreement on what globalization actually means and how it is measured. Giddens (1999) defines globalization as “the worldwide interconnection at the cultural, political, and economic level resulting from the elimination of communication and trade barriers.” He further defines it as “…a process of convergence of cultural, political, and economic aspects of life” (reported in Inkpen & Ramaswamy, 2006, p. 13). Govindarajan and Gupta (2001) define globalization as “growing economic interdependence among countries as reflected in increasing cross-border flows of three types of entities: goods and services, capital, and know-how” (p. 4).
