The following post comes to us from C. Edward Fee of the Finance Department at Michigan State University; Charles Hadlock, Professor of Finance at Michigan State University; and Joshua Pierce of the Finance Department at the University of South Carolina.
In the paper, Managers Who Lack Style: Evidence from Exogenous CEO Changes, which was recently made publicly available on SSRN, we study managerial style effects in firm decisions by examining exogenous CEO changes in a panel of 8,615 Compustat firms from 1990 to 2007. The hypothesis that managers have varying preferences or traits that affect their corporate decisions has a great deal of intuitive appeal and is implicit in many discussions of leadership. Prior empirical evidence lends support to this general hypothesis and suggests that managerial style effects play a substantive role in firms’ investment and financing choices. This raises the possibility that much of the unexplained variation in these and related choices is driven by the identities of a firm’s leaders rather than more traditional factors such as various economic tradeoffs.
While prior research on this issue has generated many interesting findings, a major weakness arises from the fact that endogenous leadership changes are used to identify style effects. In this paper we overcome this weakness by identifying a large set of exogenous CEO changes arising from deaths, health concerns, and, in some parts of the analysis, natural retirements. Quite surprisingly, we find no significant evidence of abnormal changes in asset growth, investment intensity, leverage, or profitability subsequent to exogenous CEO changes.
