Abstract
An organization that highlights the necessity to promote ethnic diversity will not only meet the demands of the market for a diverse customer base in a global hospitality setting but will also benefit the employees of an organization, with staff more likely to present higher levels of cultural competency, work motivation, and organizational commitment. Taking a systematic literature review approach, this chapter discusses the concepts of diversity and ethnic diversity and examines the importance of diversity management and ethnic diversity. More importantly, it illustrates a detailed description of status, conceptual frameworks, related theories, measurement scales, methods, antecedents, moderators, mediators, and consequences among common variables, drawing upon a comparison with critical literature on ethnic diversity in the hospitality field. The discussion provides meaningful contexts and broadens and deepens the scope of diversity-related theories. The study contributes to an enhanced understanding of how ethnic diversity can provide more advantages than it does challenges. In addition, it brings a cultural perspective to the common identity process, contributing to the broadening and deepening of social identity theory.
