In this book Harold L. Vogel comprehensively and holistically examines the business economics and investment aspects of major components of the travel industry, including airlines, hotels, casinos, amusement and theme parks, cruise lines, and tourism. The book is designed as an economics-grounded text that uniquely integrates reviews of each sector's history with economics, accounting, and financial aspects and analysis. As such, it provides a concise, up-to-date reference guide for financial analysts, economists, industry executives, legislators and regulators, advertisers, and journalists interested in the economics, financing, and marketing of travel and tourism-related goods and services. The fourth edition of this well-established text updates, refreshes, and significantly broadens the coverage of tourism economics. It includes new sections on travel law and applications of big data and artificial intelligence technologies as well as additional material on demographic spending patterns, the online travel agency business, the pandemic's effects and affects on industry finances, expanded coverage of the cruise line industry, and information on the damage to tourist destinations caused by excessive pollution and traffic. .
