The firing in recent weeks of chief executives from Vestas, Coop and NKT are a part of larger global trend that has seen 375 heads of the world’s 2,500 largest publicly traded companies lose their jobs, according to the consultancy firm Booz & Company. The figure is the highest since 2000. Other recent studies also seemed to confirm the trend by concluding that the length of time a company’s top executive stays in the job has declined. But that may not be such bad news for the company, according to Flemming Poulfelt of the Copenhagen Business School. His research has found that a chief executive’s performance declines the longer he has been with the company. – Erhverv & Økonomi
