In addition to arming shareholders and corporate watchdogs with better information on how compensation gets decided, the ruling provided financial economists Michael Faulkender and Jun Yang with an opportunity to compare the chosen peers with the peer might-have-beens. The researchers combed through the SEC filings of more than 600 companies, recording the set of peer CEOs that informed executive compensation decisions. For each CEO, they also assembled their own group of peers based on their own calculations of which other executives were most similar.
A thoroughly compromised compensation committee would pick peer firms that are larger, more profitable, and otherwise more likely to have high-earning CEOs than their own. Yet Faulkender and Yang found that by and large, there was enormous overlap between their list of peers and the ones actually chosen, so that compensation committees were for the most part being "kept honest" in choosing pay benchmarks. (Which is not to say there haven't been some flagrant exceptions to this in the past. In justifying Dick Grasso's enormous compensation package at the New York Stock Exchange—a nonprofit—the peer lists included such financial goliaths as Citigroup and Wells Fargo but no other stock exchange or nonprofit organization.)
Yet discretion did have its benefits, at least for the CEOs. The peer CEOs selected by compensation committees had total earnings that averaged nearly $850,000 more than those of ignored potential peers. The authors also calculate that each dollar of extra pay among peer CEOs was used to justify an extra $0.50 in pay, so that the favorable selection of peers resulted in more than $400,000 extra for the CEO's pay. Four hundred thousand dollars may not sound like a lot to a public accustomed to reading of $100 million bonuses to Wall Street superstars. But relative to the average CEO, with earnings of around $6.5 million, it represents a more than 5 percent pay hike.
More importantly, one executive's raise feeds into the pay hikes of others, as yet other companies will use the now 5 percent higher paycheck as a peer comparison next year. Add to the mix the fact that every year a few corporate leaders are awarded outsize compensations that allow them to leapfrog their competitors' pays (perhaps because of an exceptionally weak board, threats of retirement, or other unusual circumstances), becoming the new standard for pay comparisons in the process, and it's easy to see how a few decades of favorable peer lists could snowball into the enormous incomes we're seeing today. In fact, according to the calculations of sociologists Tom DiPrete, Greg Eirich, and Matthew Pittinsky, it is possible to account for much of the recent rise in executive pay based on the positive feedback loop and interrelatedness among CEOs' pay.
Why do compensation committees err on the side of generosity in spending shareholders' dollars on CEO pay? We all want to be a little better than average, and for board members who like to think they have an above-average CEO, this may translate into the choice of a relatively favorable pay package and a set of peers to match. Also, while boards may not be the CEO's lapdogs, they still have to face one another at future meetings (or at the country club), so when given discretion in matters of pay, it's not surprising that the board may err somewhat on the side of generosity.
This explanation for runaway salaries in the corner office isn't going to sell a lot of papers—there aren't any insidious backroom conspiracies to spin into a story of intrigue. Yet for the very same reasons, it comes across as a more likely account for the rise in CEO pay—compensation committee members are normal people, not conscienceless scoundrels, who are for the most part doing their best to attract and retain leaders. Moreover, the lesson isn't that we should dump the baby of peer comparison out with the bathwater. If CEOs and others should earn "what the market will bear," how better to figure this out than to look at how the market is treating other CEOs? But this CEO labor market will work only if all companies also keep an eye on the more basic market principle that higher CEO pay must first and foremost be tied to the success of the companies they lead.
