The Internationalization of US Franchising Systems [PDF ebook] 

This book reviews both the environmental and organizational factors of international franchising, but focuses on the latter because environmental factors can not adequately explain why some franchisers within a particular industry internationalize. This study finds that organizational factors such as the size, age, growth rate, pricing strategies and the geographical dispersion of the firm, collectively affect the franchising firm”s decision to internationalize. However, the individual variables are different in significance and magnitude for the retailing, hotel and motel, and professional business service industries.
