An emerging hospitality studies focus among academics prioritizes the study of host and guest transactions as a key feature of hospitality research and publications. The papers in this e-book, guest edited by a leading researcher in the field, provide a flavor of some of the research themes that social science perspectives suggest. The study of host and guest transactions extends beyond commercial hospitality management activities; a large number of human interactions can be better understood through host and guest transactions. Commercial hospitality management through service quality management, employee relations, customer and employee transactions as well as the development of customer loyalty can also be informed by the study of hospitality through the study of host guest transactions.
