Long-serving CEOs may weaken innovation, study finds‎

A new study from the University of East London has found that companies led by long-serving chief executives may become less innovative over time unless challenged by strong independent boards. The research examined 215 FTSE 350 companies over an 11-year period between 2010 and 2021. It explored how CEO tenure and independent directors influence a company's "R&D knowledge stock," which is the research, expertise and technological capability built through investment in innovation.
