Interactions between CEOs and their boards of directors are a prominent focus of management and strategy research. Despite the extensive literature on CEO–board relations, to date there has been limited integration of theoretical perspectives and measurement schemes. Through an extensive analysis of published studies, we hope to facilitate future research on CEO–board relations. We begin with a comparison of key theoretical approaches. Next, we conduct a content analysis of 51 empirical articles. We find that prior studies have an unbalanced focus regarding both topics and theoretical perspectives, and that there is limited consistency in the choice of measures. Based on this review, we lay out a number of promising directions for future research. We also find that, while there has been progress in international research on CEO–board relations, there are still many unanswered questions regarding the generalizability of governance theories across different geographic settings.
