Recently, there has been an increase in the number and type of studies in the organizational sciences that examine curvilinear relationships. These studies are important because some relationships have context-specific inflection points that alter their magnitude and/or direction. Although some scholars have utilized basic techniques to make meta-analytic inferences about curvilinear effects with the limited information available about them, there is still a tremendous opportunity to advance our knowledge by utilizing rigorous techniques to meta-analytically examine curvilinear effects. In a recent study, we used a novel meta-analytic approach in an effort to comprehensively examine curvilinear relationships between destructive leadership and followers' workplace outcomes. The purpose of this chapter is to provide an actionable guide for conducting curvilinear meta-analyses by describing the meta-analytic techniques we used in our recent study. Our contributions include a detailed guide for conducting curvilinear meta-analyses, the useful context we provide to facilitate its implementation, and our identification of opportunities for scholars to leverage our technique in future studies to generate nuanced knowledge that can advance their fields.

Contrary to the widely held belief in the linear positive effects of business relationships (BRELs) on performance outcomes, the authors posit that the quality of a manager's BRELs with a foreign business partner has an inverted curvilinear effect on managing challenges arising out of institutional differences between two countries, which the authors define as institutional success. The authors further propose that managers' global role complexity (GRC) negatively impacts institutional success and dampens the inverted curvilinear effects of BRELs on institutional success.

The proposed model is tested using questionnaire survey data from 186 senior Indian managers doing business with New Zealand.

The authors find significant support for the inverted curvilinear effects of BRELs and the negative effects of GRC on institutional success. They did not find significant results for the moderating role of GRC on the inverted curvilinear relationship between BRELs and institutional success. However, significant linear interactive effects of GRC and BREL are evident.

The key managerial implication is that managers should focus on building BRELs of appropriate quality with their overseas counterparts to keep producing relational rents. They should, however, also be sensitive to when such relational rents start to be eroded by internal and external factors and treat them as a dynamic equilibrium rather than a static one.

The study findings challenge the assumption of linear positive effects of BRELs within the relational view. They highlight the significance of BRELs, even for emerging economy managers doing business in advanced economies.

This research proposes and examines a theoretical model grounded in anthropomorphism theory considering the curvilinear and linear relationships between service robot anthropomorphism and consumer usage intention and explores the mediating effect of perceived risk.

To examine the developed model, two complementary studies are designed. In Study 1, multi-time data of 511 participants show that service robot anthropomorphism inverts U-shaped (curvilinear) relationship on consumer usage intention and perceived risk mediates this curvilinear relationship. In Study 2, multi-source data of 460 volunteers are used to confirm the findings of Study 1 and examine that consumer empathy moderates the complex nonlinear effect of service robot anthropomorphism on perceived risk, and the indirect curvilinear effect of service robot anthropomorphism on consumer usage intention through perceived risk.

This research provides preliminary and yet important findings on how service robot anthropomorphism most likely is positively associated with consumer usage intention, i.e. the positively influence mechanism of service robot anthropomorphism on consumer usage intention.

Drawing upon the “too-much-of-a-good-thing (TMGT)” effect and conservation of resources (COR) theory, the purpose of this paper is to examine the mediation mechanism between empowering leadership and employee job performance. Specifically, the authors propose a curvilinear relationship between empowering leadership and job performance, and also suggest that employee harmonious and obsessive work passions mediate the curvilinear relationship between empowering leadership and job performance. Further the moderation role of collectivism orientation (CO) in the relationship between empowering leadership and job performance is also examined.

Questionnaires are used to obtain survey data from 256 supervisor–subordinate dyads in three companies in the communication sector of Ghana. A follow-up interview was also conducted to enhance explanation of research findings. Hierarchical regression analysis is used to analyze the associations among the variables.

The results revealed that the significant inverted U-shaped relationship between empowering leadership and subordinate job performance is mediated by both harmonious and obsessive passion for work. A significant moderation effect of CO in the empowering leadership–job performance relationship could not be established.

This study adapts the “TMGT” effect and COR theory in the explanation of an integrated model including empowering leadership, job performance, employee passion for work, and CO in the Ghanaian context.

This study focuses on service quality and satisfaction judgments of customers in banking institutions throughout Malaysia. The study attempts to determine the relationship between service quality and satisfaction, where service quality is the independent variable and satisfaction is the dependent variable. On top of this, the inclusion of ownership as a moderator has also been studied. Findings show that service quality is the antecedent of satisfaction. The findings also support a curvilinear relationship for the variables under study. The results also show that bank‐ownership moderates the relationship between service quality and satisfaction. Hierarchical moderator regression is used to test the moderating effect. Implications and future research are also discussed.

Drawing on activation theory, this paper aims to examine the process through which abusive supervision influences job-oriented constructive deviance (JCD) in the hospitality industry.

Data are collected from 198 employees working with 34 supervisors, at three time points across four hotel groups in Macau. The instantaneous indirect effect and moderated curvilinear effect using established measures are tested.

First, abusive supervision was positively associated with hotel employees’ job dissatisfaction and their job dissatisfaction had an inverted curvilinear effect on JCD. Second, job dissatisfaction nonlinearly mediated the impact of abusive supervision on JCD. Third, high problem-focused coping decelerated the diminishing benefits of job dissatisfaction on JCD.

First, organizations should accept employees’ constructive deviance but suppress managers’ abusive supervision. Second, organizations need to improve employees’ problem-focused coping skills and channel job dissatisfaction into constructive and active behaviors.

Theoretically, the authors test a nonlinearly mediating and moderated curvilinear model and address the research concern on whether, why and how service employees decide to engage in positive deviant behaviors when encountering abusive supervision. Practically, the authors avoid concluding that moderate levels of abusive supervision can promote positive employee behaviors and refrain from justification of abusive supervision in the hospitality context.

The purpose of this paper is to examine the non-linear effects of work engagement (WE) on the job outcomes’ creative performance (CRP), extra-role customer service (ERCS) and turnover intention (TI).

Data were collected from 405 millennial frontline employees (FLEs) working in the hospitality industry in Kenya. Structural equation modeling was used to examine the hypothesized relationships.

The results yielded support for one relationship. WE was found to have a significant non-linear relationship with TI. This finding provides evidence of a ceiling to the positive impact of WE on reduced TI. WE and CRP and ERCS were however found to be non-significant and linear, and significant and linear, respectively.

A large number of studies have evidenced positive individual and organizational outcomes associated with WE. This study however, is important, as the “dark side” of WE is empirically examined, therefore providing a different perspective of the concept.

The study findings affirm that management must exercise caution with excess levels of WE among millennial FLEs as this may lead to unfavourable outcomes.

In this research, the assumption of linearity is challenged. Empirical evidence for the need to systematically explore non-linear associations for a more nuanced understanding of the relationships between variables is provided. Moreover, this study is among the few in which the presence of curvilinear relations between WE and job outcomes is examined in a non-Western context.

This study sets out to examine the potential curvilinear relationship between capital intensity and firm value for the US hospitality industry, specifically including publicly traded US hotels and restaurants, during the period 1990‐2008.

This study performs a pooled regression analysis to examine the proposed relationship. The sampled companies are from the period 1990‐2008, consisting of 281 and 1,406 observations for the hotel and restaurant industries, respectively. The study additionally performs the analysis for the 1990s and the 2000s separately for a comparison purpose.

The findings support the U‐shaped relationship between capital intensity and firm performance during the 2000s for both hotels and restaurants, while no relationship exists during the 1990s.

While the results may not be generalizable to private or non‐US hotels and restaurants, the findings should provide hotel and restaurant executives and managers with valuable information for developing their strategies with regard to the capital intensity level.

Based on the two perspectives regarding capital intensity's impact on a firm (i.e. positive and negative), a possible proposal suggests that the relationship between capital intensity and a firm's value may not be linear, but possibly curvilinear. Considering the importance of capital intensity in the hospitality industry, examinations of the issue would be beneficial for the hospitality industry.

The impact of leader-member exchange (LMX) differentiation on group performance has been considered ambiguous. The purpose of this paper is to resolve this ambiguity by theorizing and examining a curvilinear relationship between LMX differentiation and group performance, and the moderating effects of group diversity on this relationship.

Data were drawn from 63 work groups (consisting of 322 members and 63 group leaders) selected from 27 technology service companies in South Korea. Group members rated their perceived LMX quality, while the human resource (HR) directors of each company assessed group performance.

The results showed that LMX differentiation had an inverted U-shaped relationship with group performance and that gender diversity and age diversity negatively moderated that relationship. However, the interaction between LMX differentiation and education-level diversity was not significant.

This study extends extant research by addressing the inconsistency among theoretical perspectives on the effects of LMX differentiation. This study transcends earlier research by considering the complex process of LMX differentiation, such as the curvilinear relationship between LMX differentiation and group performance, and the moderating effects of group diversity on that relationship.

This study aims to investigate the impact of women’s representation at one hierarchical level on women’s representation above or below that level. No past research investigated these effects in the hospitality and tourism industries. The mixed results of research in other industries and across industries demand tests of curvilinearity and moderators.

Using annual equality reports, a panel data set for 2010–2019 was created for the hospitality and tourism industries. The sample of 581 organizations had up to 5,810 observations over the 10 years.

The analyses show the following effects of women’s representation: an inverted U-shape from management to non-management, a U-shape from non-management to management and a U-shape from management to the executive team, with more pronounced effect in small organizations.

To increase the number of female employees, organizations should invest their resources in hiring and retaining female managers until a gender balance is reached while managing any backlash from men. The results suggest that organizations with more than 40% of women non-management employees and 50% of women managers start `experiencing positive bottom-up dynamics. Thus, efforts need to be made to attract and retain a women’s pipeline at the non-management and management levels.

This study delivers pioneering evidence of the top-down and bottom-up phenomena in hospitality and tourism. It refines evidence of such effects found in past research conducted in other industries and across industries.
