The purpose of this textbook is to understand the theoretical framework of Tourism Economics from the microeconomic and macroeconomic perspectives of issues related to tourism demand and its forecasting. Specifically, it deals with the individual factors that shape it (needs, motivations, consumer patterns, tourist decision-making processes, etc.), with the production, cost of tourism, and with the supply of tourist products, as well as with the main forms of tourist markets and their balance, in which tourist units operate in the modern socio-economic reality. In addition, a special topic of Tourism Economics is examined, the Satellite Tourism Account, due to its particular interest in assessing the qualitative and quantitative dimension of tourism activity. The main changes made in this 2nd edition are as follows: Restructuring of the entire text of the first edition to make it more coherent and functional. Inclusion of additional examples in all chapters. Several new diagrams and tables for better understanding of the text. Summary of the main topics analyzed. New chapter on the theory of tourist-consumer preferences and choices. Complete restructuring of chapters related to the forms and balance of the tourist market. Indicative problems with accompanying answers that encourage recapitulation and help in checking the understanding of the text.
