Abstract

We analyze a unique database from a sample of real-world boardrooms — minutes of board meetings and board-committee meetings of eleven business companies for which the Israeli government holds a substantial equity interest. We use these data to evaluate the underlying assumptions and predictions of models of boards of directors. These models generally fall into two categories: “managerial models” that assume boards play a direct role in managing the firm, and “supervisory models” that assume that boards monitor top management but do not make business decisions themselves. Consistent with the supervisory models, our minutes-based data suggest that boards spend most of their time monitoring management: approximately two-thirds of the issues boards discussed were of a supervisory nature, they were presented with only a single option in 99% of the issues discussed, and they disagreed with the CEO only 2.5% of the time. Nevertheless, at times boards do play a managerial role: Boards requested to receive further information or an update for 8% of the issues discussed, and they took an initiative with respect to 8.1% of them. In 63% of the meetings, boards took at least one of these actions or did not vote in line with the CEO. Taken together our results suggest that boards can be characterized as active monitors.
