This study compared undergraduate international business and international management course syllabi from 190 management departments at accredited U.S. business schools. Comparisons revealed considerable overlap in topic areas in the two courses. The findings indicate the need for greater domain clarity and differentiation in objectives, topic areas covered, and textbooks used. Domain clarification could lead to more truthful representation of the two courses, better training and disciplinary grounding of course instructors, more appropriate hosting of the courses in business school departments, and enhanced skill-sets among students in these courses. Finally, clear domain definitions are necessary for reliability and validity in international business research.
