In this chapter, we synthesize the discussions in the chapters that comprise this book. This synthesis points at several themes that cut across all the chapters and appear to characterize the historical evolution of international business (IB) as a field of study. These are the role that individual scholars have played in IB’s development; the independent and concurrent development of IB thought, teaching, and institutions; the interdisciplinary nature of IB’s development that involved the blending of theory and methods from other social sciences and business functions; and the impact of contextual influences in inspiring renewed perspectives on IB phenomena and thought development. We also offer projections about where IB might go in the future within the interactive dynamics among IB thought, teaching, and institutions. We suggest a need to delve into issues related to unit of analysis and to deepen understanding of IB’s interdisciplinary identity and the way it shapes the boundaries of IB and its future as a field of study.
