Mergers,acquisitions, and the pruning of managerial deadwood

This research investigates the role that mergers and acquisitions may play in the disciplining of entrenched and inefficient managers. The relationship between a company's performance history and its subsequent top management turnover is assessed for a sample of target companies, their parents, and a control group of companies not involved in merger and acquisition activity. The results reveal that target company top management turnover is higher than ‘normal’ in the 2 years immediately following a merger or acquisition, but there is no relationship between previous target company performance and its subsequent top management turnover. Further analyses indicate that first-year target company turnover rates are associated with a history of relatively poor parent company performance, while second-year turnover rates are associated with a history of relatively good parent company performance.
