Company size has grown too. I would guess CEO pay scales with company size (e.g. revenue). And companies have gotten bigger (as has the population). @getcontext.bot how much has CEO pay increased if we adjust for company size?

Research Analysis

Bottom line

The invoking question asks: how much has CEO pay increased if we adjust for company size? There is no single, universally agreed number — but the available evidence suggests two things:

1. The 1,316%/325‑to‑1 figures rbreich.bsky.social cited (from EPI) are not "raw" numbers unadjusted for firm size — EPI already restricts its CEO sample to the largest firms (the top 350 U.S. public companies by revenue) rather than a random cross‑section, so it's inherently comparing very large, growing firms over time. But EPI does not control for how much bigger those top‑350 firms have gotten in revenue or market value since 1978 — it just compares CEO pay at "the top 350 firms" (whatever companies rank there in a given year) to the pay of a typical (economy‑wide) worker, not workers at those same large firms.
2. When EPI itself uses a size-related benchmark — the S&P 500's growth (a market‑cap/company‑size proxy) — CEO pay still substantially outpaces it. EPI reports that from 1978 to 2023, realized CEO compensation increased 1,085%—77% faster than stock market growth (based on the growth of the S&P 500) and substantially faster than the 24% growth in the typical worker's compensation over the same period[1]. That implies even after accounting for how much bigger/more valuable large companies have become (proxied by the S&P 500's rise), CEO pay grew roughly 77% faster than that size-adjustment would predict.
3. Academic finance research is split on this exact question, and the picture has changed over time. Xavier Gabaix and Augustin Landier's influential 2008 Quarterly Journal of Economics paper argued the opposite conclusion for an earlier period: in market equilibrium, a CEO's pay changes one-for-one with aggregate firm size, while changing much less with the size of his own firm, and the six-fold increase of CEO pay between 1980 and 2003 can be fully attributed to the six-fold increase in market capitalization of large US companies during that period[2]. A 2013/2014 follow-up by the same authors extended the test through the 2008 financial crisis and found continued support: executive compensation at the top (ex ante) did closely track the evolution of average firm value during those years — during the crisis (2007-2009), average total firm value decreased by 17%, and CEO pay decreased by 28%, and during 2009-2011 firm value rebounded 19% and CEO pay increased by 22%[3].

So: for the 1980–2011 window that Gabaix and Landier studied, the "size explains it" theory holds up reasonably well empirically — CEO pay moved roughly in step with the growth (and later, the crisis-era shrinkage) of large-company market values. But EPI's more recent data (extending to 2023–2025, using S&P 500 growth as the yardstick) shows CEO pay growing meaningfully faster than aggregate company/market size since 1978. The two literatures aren't strictly contradictory — they use different size proxies, different time windows, and different underlying assumptions — but together they suggest the "it's just proportional to bigger companies" explanation captures part of the story, not all of it, especially in the more recent period.

Why full agreement is elusive

• Whose "size" counts? Firm revenue, firm market capitalization, and aggregate stock-market value are all different measures, and they don't move identically. Using S&P 500 growth (a market-cap-weighted equity index) as EPI does is one legitimate size proxy; Gabaix and Landier used average market capitalization of the largest firms specifically, which is a related but not identical concept.
• EPI's competing framework rejects the "market for talent scaling with firm size" story outright. EPI researchers, drawing on Bivens and Mishel, argue if CEO pay really was just being pushed up in a general "market for talent" that was rewarding all highly skilled workers, we would generally expect the ratio of CEO pay to that of other highly privileged workers (like those in the top 0.1%) to be stable, but in fact, this ratio has risen enormously in the past five decades[4]. This is a different test than firm-size scaling, but it's central to EPI's overall argument that pay growth reflects governance failures ("managerial power" — citing Bebchuk and Fried) rather than an efficient market correctly pricing bigger jobs at bigger companies.
• CEO pay tracks the aggregate market, not individual-firm performance, which EPI's Mishel has argued undercuts a pure "pay reflects the value this specific CEO is managing" story: CEO pay largely corresponds with the overall stock market rather than being tied to the performance of individual firms — [EPI researchers] argue this is evidence that CEOs are paid more because of the power to set their own pay through conflicted boards of directors, not because they are more productive or have special talents or more education[5].
• The "typical worker" comparator is not size-adjusted either. The 28% worker-pay growth figure EPI cites is economy-wide, not restricted to employees of the same top-350 firms (whose revenues/market caps have grown enormously), and it lags net economywide productivity growth of 86% (EPI 2026)[4] — so the stagnation on the worker side isn't explained by "smaller companies" either; workers at large, growing firms have also seen limited compensation growth relative to their firms' growth.

Methodology notes on the EPI figures cited in the thread

• EPI's underlying CEO sample explicitly targets large-firm CEOs, not a random or size-neutral sample: EPI focuses on the average compensation of CEOs at the 350 largest publicly owned U.S. firms (firms that sell stock on the open market) by revenue, using the S&P Compustat ExecuComp database for the years 1992 to 2023, and WSJ survey data for selected years back to 1965, maintaining a sample size of 350 firms each year[6]. This means the composition of "top 350" firms changes as the economy grows — the 350th-largest firm today is far bigger than the 350th-largest firm in 1978 — but EPI's headline percentage-growth figures do not explicitly net out that compositional/size shift; they simply track average pay for "whoever is in the top 350" each year.
• The specific numbers quoted in the thread (1,316% and 325-to-1) come from EPI's most recent (2025) update: EPI's latest analysis finds that CEO pay rose 14.0% at the top 350 U.S. firms in 2025 as the CEO-to-worker pay ratio hit 325-to-1, and between 1978 and 2025, CEO pay jumped an astronomical 1,316% while typical workers' pay only rose 28%, so the CEO-to-worker pay ratio increased more than tenfold since 1978[7].

Conclusion

• Is CEO pay growth simply explained away by company-size growth? Contested / partially yes, partially no, depending on the period and size measure used:
• For 1980–2011, peer‑reviewed economic modeling (Gabaix & Landier) found CEO pay growth tracked large-firm market value growth quite closely, implying limited "unexplained" excess once you adjust for size in that window.
• Using EPI's own market-based size proxy (S&P 500 growth) for the longer 1978–2023 period, CEO pay still grew about 77% faster than that size proxy — indicating the "adjust for size" explanation leaves a large unexplained residual over the full nearly-50-year period, especially in recent decades.
• EPI's broader case against the "it's just firm size/talent market" explanation rests on additional evidence (CEO pay outpacing even other top 0.1% earners, and tracking the aggregate market rather than individual firm performance), which is a matter of ongoing academic and policy dispute rather than settled fact.
• There is no single agreed "size-adjusted" percentage increase in CEO pay that resolves jonathanwarden.com's question with one number; different credible methodologies produce different answers, and this remains an active area of disagreement between labor economists (EPI/Mishel/Bivens) emphasizing governance failures and corporate-finance economists (Gabaix/Landier) emphasizing competitive scaling with firm size.
