Beware the leadership myth of the great chief executive

[Archean]

Citing research by Jonathan Haskel of Imperial College Business School, he says: "Most of the productivity growth in the 1980s occurred through firms entering and exiting the market rather than from individual firms improving their productivity.

"What that tells us is that the ability of managers to make their company more efficient is perhaps not as great as we think and we overestimate the ability of managers to improve their companies," he says.

Very interesting read IMO.
