International joint ventures (IJVs) are an important type of international strategic alliance (ISA) and have been studied by scholars for decades, resulting in a plethora of empirical studies, publications, and reviews, yet an inadequate accumulation of knowledge exists, as a closer look reveals. Much more than providing a summary and critical assessment of past contributions, this paper develops an expansive research agenda based upon a deep understanding of past research and comprehensive frameworks that distill this research. We identify a number of research opportunities that would not only advance IJV research but also closely related literatures and disciplines such as ISAs, theories of the multinational firm, international business research, and strategic management.
