This paper investigates how managerial expertise—specifically, industry expertise—affects firm value through divestiture. Using CEOs’ managerial experiences in industries throughout their careers as a measure of their industry expertise, I find that CEOs in diversified conglomerates are more likely to divest divisions in industries in which they have less experience. This finding is consistent with CEOs who divest such divisions in order to refocus on those divisions in which they have specialized—that is, to achieve a better match between their expertise and their firms’ retained assets. Firms that divest for a better CEO-firm match experience significant improvements in operating performance, as well as significant abnormal stock returns that persist for an average of three years following a divestiture. Further, among firms that divest for a better match, those firms with more experienced CEOs realize greater gains in firm value. In contrast, divestitures that increase corporate focus, but do not improve the expertise-asset match, do not lead to long-run increases in firm value.

We propose and test a new explanation for forced CEO turnover, and examine its implications for the impact of firm performance on CEO turnover. Investors may disagree with management on optimal decisions due to heterogeneous prior beliefs. Theory suggests that such disagreement may be persistent and costly to firms; we document that this induces them to sometimes replace CEOs who investors disagree with, controlling for firm performance. A lower level of CEO-investor disagreement serves to partially “protect” CEOs from being fired, thus reducing turnover-performance sensitivity, which we also document. We also show that firms are more likely to hire an external CEO as a successor if disagreement with the departing CEO is higher. Disagreement declines following forced CEO turnover. Using various empirical strategies, we rule out other confounding interpretations of our findings. We conclude that disagreement, independently of firm performance, affects forced CEO turnover.
