Discusses research in the literature about the expatriate manager as a unit of resource. The research to date has largely addressed concerns for the high failure rate and costs of expatriate assignments, suggestions for improving methods of personnel selection; comparative studies of expatriate and local managers; and recommendations for improving expatriate success. Notes that rarely are the problems of expatriate personnel addressed collectively, particularly with a focus on Asia. Discusses effectiveness of expatriate assignments within the totality of four distinctive phases: selection; preparation; acculturation; and repatriation. Provides a valuable foundation for providing organizational recommendations to enhance the success of future expatriate placements.
