This is the first book to bring together expert researchers in the field of expatriate studies. The need for such a book is timely. The world is becoming smaller with the international movement of individuals – as expatriates, business travellers, highly skilled workers and migrants – at an all time high. Expatriation is being increasingly researched and taught in business schools as part of broader and more general international human resource management (IHRM) and global business courses. Expatriates are increasing in their number and profile, with many different types, and many issues and challenges they must overcome. This Research Handbook of Expatriates brings together the work of some of the world’s leading and up-and-coming scholars to present a solid overview of the field of expatriate studies to date, as well as to inform and excite future academic scholars and practitioners to the possibilities of conducting, collaborating on or utilizing research arising from expatriate studies. In this introductory chapter, we illustrate that expatriation as a teaching and research subject has existed for over 60 years. Although it is often assumed that the birth of expatriate studies occurred in the 1980s with publications by Rosalie Tung and J. Stewart Black, or perhaps a little earlier in the 1970s with studies by Anders Edstrom and Jay Galbraith, a review of extant literature shows that a substantial body of expatriate research existed well before this time. We provide an overview of expatriate studies from 1952 to 1979 highlighting that, while much of this early literature (and most especially pre-1970) was lacking in theoretical grounding and with only a few empirical studies published, it nonetheless provided an initial foundation upon which subsequent research and interest in expatriate studies would come to be based. We similarly highlight research by a core group of early scholars whose names would become synonymous with research about expatriates. Although long forgotten today, we owe a debt of gratitude to Cecil Howard, John Ivancevich, Yoram Ziera, Anant Negandhi, and Edwin Miller (among others) for pioneering early expatriate studies.
