Study: Highest-Paid CEOs Have Worst Company Performance

``The study shows that CEOs who get paid huge amounts become overconfident and tend to think less critically about their decisions... Cooper and two professors, one at Purdue Universtity and the other at the University of Cambridge, studied data from 1,500 companies with the biggest market caps. They were surprised to find that the more CEOs got paid, the worse their companies did. At the very top, the 5 percent of CEOs who were the highest paid turned in the worst company performance -- 15 percent worse than the average.''
