External hire premium
The controlled estimates, the models behind them, and the same question asked in a second market.
Headline
Among external hires, the amount paid over the departing CEO does not signal the return that follows. It holds after controls for firm size, year, and industry. It holds when the return is measured only after the hire. It is the most robust result in the study, because it is a within-relationship slope, not a level comparison, so the selection of troubled firms does not drive it.
What holds
Premium to stock return: p = 0.14. Premium to operating return: p = 0.45. Both indistinguishable from zero, under full controls and a post-hire window.
What does not hold
The cost premium is directional but imprecise. The weaker returns are mostly selection. The flashy claim does not survive scrutiny.
The numbers
| Question | Measure | Estimate | Verdict |
|---|---|---|---|
| Cost more? | pay vs. predecessor, controlled | +9% (p = 0.54) | directional, not precise |
| Worse stock performance (raw window)? | market-adjusted TSR, −2/+3yr | −38 pts (p < 0.001) | confounded by selection |
| Worse stock performance (after the hire)? | market-adjusted TSR, hire to +3yr | −12 pts (p = 0.14) | not significant |
| Worse operating performance? | ROA change | −2.5 pts (p = 0.009) | small, real |
| Premium predicts return? | return on premium, controlled | ≈ 0 (p = 0.14 / 0.45) | No. holds. |
| Shorter tenure? | Cox hazard, external | HR 1.28 (p = 0.20) | not significant |
The models
Each uses robust (HC1) errors. Controls are firm size (log assets), appointment year, and two-digit SIC industry.
The premium. Do external hires cost more?
β = +0.088, p = 0.54, n = 236. Bidwell-sized, not significant on the mean, significant on the median test (p = 0.007).
The return, after the hire. Do external hires deliver worse?
β = −0.119, p = 0.14, n = 431. The full straddling window gave −0.385 (p < 0.001); most of that was inherited decline. ROA change keeps a small effect: −0.025, p = 0.009.
The headline. Does the premium predict the return?
β ≈ 0, p = 0.14 (stock), 0.45 (operating), n = 189. The slope is flat.
Tenure. Do external hires last as long?
hazard ratio = 1.28, p = 0.20. Directionally shorter, not significant.
Selection
External hires concentrate in firms whose stock lagged the market, not firms in operating crisis, and not in every case. This is measured, not assumed.
Two markets, one answer
Both price outside talent off a recent peak that tends not to last. The CEO work leads. The sports studies corroborate.
| Market | Premium paid for | Predicts return? | Key statistic |
|---|---|---|---|
| CEO hires, S&P 500 | external pay over predecessor | No | premium to return p = 0.14 / 0.45 |
| NHL free agency | offseason UFA spend | No | prior to next slope −0.42, p < 0.001 |
| NFL free agency | top-spender status | No | top spender is not top win-gainer |
| NBA supermax | supermax contract | No | penalty vanishes with controls |
| NHL play-for-contract | cap share, retention | retention wins | same-team +0.70, p < 0.0001 |
