Abstract: | This paper analyzes the direction and magnitude of changes in stock prices resulting from the announcement of various types of changes in senior corporate management over a twelve-year period. We find support for the view that instability resulting from executive succession adversely affects organizational performance. Furthermore, our results imply a clear preference by the market for a change in composition of the previous management team over its further entrenchment and a perception by the market that senior corporate executives and the board of directors may not be solely motivated by considerations of shareholder wealth maximization. |
