The increasing interest over the last dozen years or so in other forms of international experience, often equally poorly conceptualized, has compounded the problem. We argue for the need for greater construct clarity in studies of expatriates and, by extension, of other forms of international experience. Specifically, we attempt to clarify to whom does the term 'expatriate' , and specifically 'business expatriate' , apply and the boundary conditions under which expatriate employment is enacted.

Many managers in global firms regard the ability to obtain a return on investment (ROI) from expatriates as important, given the substantial costs associated with global staffing practices, particularly international assignments, and the risks and uncertainties of deploying key talent. This research examines how expatriate ROI is measured for longterm assignments in 51 global firms, across 18 industries, and with headquarters in North America, UK, Europe, Africa, and Asia Pacific. Our findings suggest that firms do not have formal procedures in place to measure expatriate ROI and instead rely heavily on informal practices that are seldom aligned to a global strategy. Cultural, operational, and strategic barriers to measuring ROI also exist. In addition, we are challenged to consider whether measuring expatriate ROI is actually a goal for managers in global firms, given the evidence which suggests that for some firms having expatriates is often a cost of doing business for which a formal measure may be unnecessary. An alternative view suggests that if international assignments are considered a necessary cost of doing business for global firms, how expatriates are managed in terms of the HR practices that support their activities and how the outcomes of those activities impact broader firm performance may be far more important concerns. Based on evidence that the nature of expatriation is rapidly changing, we conclude that expatriate ROI remains a challenging and complex process that managers in global firms are currently not well-equipped to address. The findings have important implications for the planning and management of international assignments.

AbstractPurpose -The purpose of this paper is to introduce the emerging international career phenomenon of the "expat-preneur," an individual temporarily living abroad who initiates an international new venture (self-employment) opportunity in a host country. Design/methodology/approach -This analysis is based on the authors' observance of developing trends that also are showcased in the international management and IHRM literatures. Findings -Two general types of expat-preneurs are proposed: first, pre-departure expat-preneurs who move abroad with a preconceived entrepreneurial purpose; and second, transitioned expat-preneurs who, only while abroad, recognize and pursue a new venture opportunity, either from the status of selfinitiated expatriates (SIEs) looking for local employment or while serving as organization-assigned expatriates and leaving the organization at the end of the assignment or midstream. Research limitations/implications -Distinctions between expat-preneurs and typical business SIEs are explored, and important contributions that expat-preneurs may provide in strengthening local host country economies are considered. Directions for further systematic and empirical research on the expat-preneur international career phenomenon are discussed. Practical implications -Important mutually beneficial implications are noted for multinationals in supporting expat-preneurs' long-term success in host country environments. Originality/value -This conceptual study provides a valuable recognition and analysis of an important and growing international career category that has received scant attention in the literature. This research has important implications for the understanding of new international career dynamics associated with the growing trend of international entrepreneurship, especially valuable for emerging markets and of interest to multinational firms interested in the movement of their human capital.
