The news that bosses' pay has soared raises a question no-one seems keen to ask: what, exactly, do bosses contribute to company performance?
Truth is, it's not clear that they add anything.
Take Terry Leahy, CEO of Tesco. He's probably the most respected FTSE 100 boss. So you'd expect Tesco's performance to be much better than its competitors. Is it? Well, these figures show that in 2005-06, Waitrose made a profit of £11,830 per full-time equivalent worker. Figures here suggest Tesco's profit per worker was £8350. Leahy's allegedly superior management nous doesn't translate into obvious out-performance of a worker-owned competitor.
And this might be true generally: other evidence suggests worker-owned firms beat orthodox capitalist ones.
So, do bosses matter? The best recent evidence that they might comes from this paper. The authors looked at what happened to Danish companies after bosses die. They found that profits fall by an average of 18% in the two years after the death of a CEO. This suggests CEOs do create profits. What's more, profits also fell if the CEO suffered a death in the family - a child, spouse or parent but not (in vindication of Les Dawson) mother-in-law. This suggests company performance suffers if the boss takes his eye off the ball*.
Sounds convincing? No.
First, the study found that it's only CEOs' deaths that reduce profitability; the death of board members makes no difference, which suggests most top executives don't add to profits.
Secondly, the CEOs who die might not be a random sample of all CEOs. They might be better than average ones - say, because they are unusually highly driven and so more prone to heart disease. If so, falling profits after their deaths might merely show that better-than-average bosses create profits, not that the average boss does. Evidence for this is that corporate profits were higher than average in these firms before the CEO died.
Thirdly, the paper leaves unanswered the mechanism whereby CEO death depresses profits. If profits fall because candidates to replace him jockey for the top job rather than do their own job, then this is evidence that hierarchy is bad for firm performance.
Fourthly, this might be evidence not that management works, but rather that the belief in management works. Maybe centuries of indoctrination by leadership ideology has led people to think that they can and should work hard only if a boss is there to lead or motivate them.
An analogy might help. Say a medieval scholar wanted to find if God existed. So he looked at villages whose priest died. And he found that sin in these villages rose relative to villages where the priest stayed alive. He infers that God as mediated by the priest is a force for good.
But this inference wouldn't necessarily be correct. Maybe God doesn't exist, and the priest is just a charlatan, and all the scholar has found is that people believe erroneously in the magic of the priesthood.
I draw this analogy because Alasdair MacIntyre did:
"Managerial effectiveness" functions much as Carnap and Ayer supposed "God" to function. It is the name of a fictitious but believed-in reality, appeal to which disguises certain other realities.
Perhaps in a few decades' time, we shall regard CEOs in the same way atheists today regard the corrupt medieval clergy - as people who exploited a fictitious and regressive ideology to accumulate power and wealth at the expense of others.
