This e-book looks at the role of modelling in tourism management. In the last five decades, the role and importance of quantitative research in tourism has been well understood because of the emerging need for methodological evidence related to theoretical assumptions. Furthermore, the inter-disciplinary characteristics of tourism management enabled tourism researchers to undertake more collective studies with researchers from other disciplines (such as economics, psychology, sociology and biology). With its growing scope of research and complex characteristics, tourism management has become therefore an attractive research field for all researchers.
