Japanese keiretsu: Past, present, future

This article reviews major theoretical and empirical work on vertical and horizontal Japanese keiretsu. We first outline the history, characteristics, and strategic and performance implications of each type of business group. We then discuss changes in the Japanese economy during the post-1992 Japanese economic decline and their implications for the persistence and continued benefits of each form of inter-corporate grouping followed by a discussion of empirical findings regarding the continued role of keiretsu in the Japanese economy. The review concludes by exploring areas of future research into the evolution of keiretsu ties and their implications.
