Is “shareholder primacy” a problem?
Elizabeth Warren and Marco Rubio agree on almost nothing — except that the rule “companies exist to maximize shareholder value” broke American capitalism. When the left and the right indict the same doctrine, is the doctrine the problem?
The cross-partisan indictment
“Trillions of dollars that could have been spent on innovation and job creation in the U.S. economy over the past three decades have instead been used to buy back shares for what is effectively stock-price manipulation. Corporate profitability is not translating into widespread economic prosperity.”
— William Lazonick, “Profits Without Prosperity,” Harvard Business Review, September 2014
Lazonick’s indictment has a name: “downsize-and-distribute.” The modern corporation, he argues, stopped reinvesting in productive capacity and started extracting cash for shareholders. What makes the claim hard to dismiss is who repeats it. On the left, Elizabeth Warren’s Accountable Capitalism Act (2018) would have federally chartered large corporations and required 40% worker-elected boards — explicitly to dethrone shareholder primacy. On the right, Marco Rubio’s “common-good capitalism” and the American Compass project argue that shareholder-primacy financialization hollowed out American industry. When Warren and Rubio reach the same verdict, the question stops being partisan and becomes a fault line.
To take the fight seriously you need one distinction, and only one. There are two readings of what a corporation is. The residual-claimant view: the corporation is owned by its shareholders, who put up the capital and bear the residual risk — they get paid last, only what remains after everyone else is paid — so managers owe their duty to them. That is the shareholder-primacy default. The nexus-of-stakeholders view: the corporation is a coalition — customers, employees, suppliers, communities, and shareholders — bound together by contracts, and no single party has a unique claim on what it’s for.
That is the whole fault line. The critics say the residual-claimant default is broken; the defenders say it is the only reading that produces accountability. The rest of this walkthrough is the argument between those two readings — and it is a real argument, not a slogan-trade. The framing of what a market and a firm are for lives in the foundations chapter.
“From the end of World War II until the late 1970s, a retain-and-reinvest approach to resource allocation prevailed… Since the early 1980s, that mode has given way to a downsize-and-distribute regime of reducing costs and then distributing the freed-up cash to financial interests, particularly shareholders.”
— William Lazonick, Harvard Business Review, 2014
Did the corporation stop reinvesting?
Lazonick’s claim is that something changed around 1980: the corporation switched from building productive capacity to extracting cash for shareholders. Is that a real shift in what firms do — and is shareholder primacy the cause, or just the rule it happened under?
A fault line, not yet an argument
“The economy will not work for working Americans until corporate America once again works for working Americans.”
— Elizabeth Warren, on introducing the Accountable Capitalism Act, 2018
The critic’s opening move is to point at the convergence itself. When a progressive senator and a national-conservative senator independently conclude that shareholder primacy broke the link between corporate profit and shared prosperity, the burden of proof shifts: this is no longer one side’s grievance. Warren and Rubio diagnose the same disease and even reach for similar cures — re-charter the corporation, put non-shareholders on the board. The doctrine, the critic says, is the thing both wings are pointing at.
“Broken compared to what? Every governance rule has failure modes. The question is whether the proposed cure has fewer.”
— the defender’s first reply
The defender doesn’t deny the convergence — it concedes there is something to explain. But it presses two questions the indictment skips. Broken compared to what alternative, evaluated by what standard? And if the cure both wings reach for is “hand the corporation to a board accountable to everyone,” is that a cure, or a different and possibly worse disease? “The left and the right both hate it” establishes that something is on the table. It does not yet establish that the doctrine is wrong, or that abandoning it would help.
Where this leaves us
When Elizabeth Warren and Marco Rubio indict the same rule, something real is on the table — this is a fault line, not a partisan banner. But “the left and the right both hate it” is not yet an argument that it is wrong. Two questions have to be separated, and the rest of this walkthrough separates them. First: does shareholder primacy actually produce the pathologies the critics charge? And second — the question the critics almost never ask — if it does, what actually fixes them? Because the answer to the second might not be the answer the critics assume.
Start by taking the critique completely seriously — not as populism, left or right, but as economics. Suppose shareholder primacy really does dump costs on everyone who isn’t a shareholder, expropriate the workers and towns that bet on a firm, and starve the future to feed the quarter. Does the economics actually say that? It does — more than you might expect.
The case that it’s a problem
“Like a fine wine, decisions in a firm should mature over time. Short-termism means picking the low-hanging fruit and ignoring the orchard. It is the financial equivalent of eating the seed corn.”
— Andrew Haldane, then Chief Economist of the Bank of England, “The Costs of Short-termism,” 2015
Here is the critique at its strongest — not “executives are greedy,” but a claim grounded in the economics of externalities, incomplete contracts, and capital-market myopia. The case is that shareholder primacy is not first-best efficient, and that its inefficiencies fall predictably on the people who aren’t shareholders. That is mainstream microeconomics, not grievance. Take it apart and there are three distinct mechanisms.
Shareholder primacy delivers efficiency under a strong condition: that the firm faces the full social cost of everything it does, and that every contributor to the firm is fully protected by contract. Drop either assumption and the doctrine stops being first-best. Both assumptions fail in the real world, and they fail in three specific ways.
1. Externality-dumping. A firm maximizing shareholder value will offload any cost it is not charged for. Pollution it doesn’t pay to emit, systemic risk it doesn’t pay to create, the burden on a community when a plant closes — if the price system doesn’t bill the firm for it, shareholder-value maximization actively rewards dumping it. This is not a moral failing of executives; it is the model working as designed. The firm is first-best only when externalities are priced, and they are not. So the firm dumps.
2. Stakeholder-specific-investment hold-up. A worker who trains in firm-specific skills, a town that grows up around a single plant, a supplier who re-tools for one buyer — each makes an investment worth a great deal inside the relationship and little outside it. That gap is a quasi-rent, and under a shareholder-only regime the residual claimant can capture it: renegotiate the wage, close the plant, switch suppliers, after the specific investment is sunk. Contracts can’t fully protect against this because they can’t anticipate every contingency — that is the incomplete-contracts core of the problem. The firm-as-coalition-of-specific-asset-holders is exposed to hold-up that a shareholder-only objective does nothing to prevent.
3. Short-termism, at the margin. Quarterly-earnings pressure and capital markets that discount distant payoffs steeply bend some managers toward starving R&D and funding buybacks instead of investment. Buybacks are the headline exhibit of this mechanism — the most-quoted way critics say the doctrine starves the future. The buyback-specific evidence (whether buybacks macro-starve investment, the Modigliani-Miller payout-equivalence, the EPS-gaming case) is litigated in its own walkthrough, Are stock buybacks bad?. Flag it forward: that walkthrough’s verdict is that the macro version of the short-termism claim mostly fails — which is the seam Stage 3 walks back through.
The first two mechanisms are the load-bearing ones, and they are not contested in their existence. Externality theory and incomplete-contracts theory are mainstream microeconomics, and they say plainly that shareholder primacy is not first-best. The apparatus lives in two chapters: market failures for externalities and incomplete contracts, and institutional economics for the theory of the firm as a nexus of specific-asset holders.
“Decisions in a firm should mature over time… Short-termism is the financial equivalent of eating the seed corn.”
— Andrew Haldane, Bank of England, 2015
Is shareholder value a license to socialize costs?
The strong claim: “maximize shareholder value” means privatize the gains and socialize the costs — pollution, systemic risk, the expropriated worker and town — onto everyone who isn’t a shareholder. How much of that is the model working as designed?
The defects, and the first crack in the cure
“The public corporation is best understood not as the private property of shareholders but as a team of stakeholders — investors, employees, suppliers — who pool firm-specific resources and need their joint enterprise governed in the interest of the whole team.”
— the team-production tradition, after Margaret Blair & Lynn Stout, “A Team Production Theory of Corporate Law,” 1999
The critic’s lineage is old and serious. It descends from Berle and Means’ 1932 observation that ownership and control had already separated in the modern corporation, through the institutionalist reading of the firm as a coalition rather than a piece of property, to Lazonick’s financialization critique. That tradition — Veblen and Commons through the team-production theorists — is the home of the claim that the firm is a nexus of specific-asset holders whom a shareholder-only objective leaves exposed. Its history lives in the institutionalist chapter of the economic-thought book.
“Grant every defect. The question is still: who runs the firm instead, and who holds them to account? A cure that loses the one thing the doctrine does well is not obviously a cure.”
— the defender’s bridge to Stage 3
The defender does something unusual here: it concedes the diagnosis and contests the cure. Yes, the defects are real — externality-dumping and hold-up are genuine, and pretending otherwise would be dishonest. But two things follow that the critic skips. The proposed cure — hand the firm to a board accountable to all stakeholders — would lose the single feature that makes managers answerable to anyone. And the biggest of the three defects, short-termism, rests on an empirical claim that doesn’t survive contact with the aggregate data. Concede the defects; deny that they license abandonment. That is the bridge into the defense.
Where this leaves us
The critique is correct that there are real defects. Shareholder primacy is not first-best — externality-dumping is real wherever externalities are unpriced, stakeholder-specific investments are genuinely exposed to hold-up, and short-termism bends some managers at the margin. The critics have won this much, and it matters. But there is a chasm between “shareholder primacy has real defects” and “abandon shareholder primacy.” The first is about diagnosis; the second is about cure. And the cure the critics reach for might cost more than the disease — while the biggest of the three defects might be smaller than they claim. The market-power face of cost-dumping has its own answer in Do big tech companies have too much power?; the pollution face in Should we put a price on carbon?.
So shareholder primacy has real defects. Does that mean we should scrap it? Here is the question the critics — left and right — keep not answering: if managers don’t owe their duty to shareholders, who do they owe it to, and who can hold them to it? Because there is one thing shareholder primacy does that no proposed replacement has matched. And while we’re at it: is the short-termism story actually as bad as Lazonick says? Two economists say no — and they have the data.
The agency-theory defense
“There is one and only one social responsibility of business — to use its resources and engage in activities designed to increase its profits so long as it stays within the rules of the game… A corporate executive who spends shareholders’ money on ‘social responsibility’ is spending someone else’s money for a general social interest — and on whose authority?”
— Milton Friedman, “The Social Responsibility of Business Is to Increase Its Profits,” The New York Times Magazine, September 13, 1970
Fifty years before Warren and Rubio agreed shareholder primacy was broken, Milton Friedman gave the reason it became the default — and it wasn’t ideology. It was that a duty to shareholders is the only corporate duty you can actually enforce. Read past the culture-war reputation and the 1970 essay is making a governance argument: a manager spending other people’s money on “social responsibility” is answerable to no one for how he spends it. And on the empirical side, the most-cited defect of all — short-termism — turns out to be the one the data supports least.
Shareholder primacy is not, at root, an ideology. It is the standard solution to the agency problem. Managers have private information and private incentives; left to themselves they will favor empire-building, quiet life, perks, and self-dealing over value. Something has to discipline them. Shareholder primacy supplies a single accountability metric — shareholder value — and a single residual-claimant principal — the shareholders, who bear the residual risk and therefore are handed the residual control right: they can vote, sue, sell, and replace the board. The metric is measurable and the principal has both the incentive and the legal standing to enforce it.
Why the diffuse alternative is worse, not just different. A mandate to “balance the interests of all stakeholders” hands managers a metric for everything — and a binding constraint from no one. If you are accountable to shareholders, workers, suppliers, communities, and the environment all at once, then any decision can be justified by appeal to some stakeholder, and no stakeholder can prove you wrong. A duty to everyone is a duty with no enforcer. The result is precisely the unaccountable managerialism that the institutionalist critics — Berle and Means, later Galbraith with his “technostructure” of managers running the firm for themselves — warned about most loudly. The cure the critics reach for resurrects the disease their own intellectual ancestors feared. The systematic Friedman-vs-Galbraith framing of that managerialism worry lives in Friedman vs. Galbraith on the mid-century economy.
And the short-termism thesis is empirically contested. The most-cited defect — Lazonick’s downsize-and-distribute — is the least empirically secure. Mark Roe (“Stock Market Short-Termism’s Impact,” 2018) and Jesse Fried with Charles Wang (“Short-Termism and Capital Flows,” 2019) push back hard: aggregate R&D and investment did not collapse the way a literal downsize-and-distribute reading implies; net shareholder payouts, measured properly, are a fraction of the gross buyback figure because firms also raise equity; and the cash returned to shareholders is reinvested elsewhere in the economy, frequently in younger and more productive firms. Short-termism is real at the margin — it is not the systemic hollowing-out the strongest critique claims. The buyback-specific version of this calibration, including why the macro “buybacks starve investment” claim mostly fails because the capital reallocates, is the verdict of Are stock buybacks bad?.
The apparatus is the agency / principal-agent framework and the residual-claimant logic — why the party that bears the residual risk is handed the residual control right. Both live in the microeconomics chapters.
“A corporate executive… has direct responsibility to his employers… to conduct the business in accordance with their desires.”
— Milton Friedman, The New York Times Magazine, 1970
Is shareholder primacy the only doctrine you can enforce?
The defense’s strong claim: shareholder primacy is the one corporate-governance doctrine with a real accountability mechanism — one metric, one principal who can vote, sue, sell, and replace — and the short-termism panic is overstated. Does the accountability argument survive the defects from Stage 2?
Accountability to the wrong objective
“The shareholder-value norm gives the corporation a single objective function. Without it, managers maximize their own discretion. The accountability you lose is real, and nothing in the stakeholder model replaces it.”
— the agency-theory defense, in the Jensen-Meckling / Chicago tradition
The defense’s lineage is the counter-revolution. Friedman’s 1970 essay and the Chicago program — Jensen and Meckling’s 1976 agency theory, the formal case for shareholder-value-maximization as the firm’s objective function — built the apparatus that makes shareholder primacy more than a slogan. That program’s home is the counter-revolution chapter of the economic-thought book, alongside monetarism and rational expectations; it is not the information-economics chapter, despite both touching on incentives and information.
“The accountability mechanism is real — and that is the problem. A firm perfectly disciplined to maximize shareholder value is perfectly disciplined to dump costs and expropriate quasi-rents. The most accountable shareholder-primacy firm is the most dangerous one.”
— the critic’s strongest rebuttal
This is the critic’s strongest reply, and it is not a walkover — it grants the defense its best point and turns it. Yes, the accountability mechanism works. But accountability is a direction, not a destination: it disciplines the firm toward whatever objective it encodes, and the objective it encodes ignores the unpriced externality and the under-protected specific investment. The defender’s counter-counter is the pivot of the whole walkthrough: that is true — which is exactly why the fix is to change what the firm is accountable for at the margin (price the externality, protect the specific investment) through external policy, and not to dissolve the accountability mechanism that makes managers answerable to anyone at all. Whether the proposed stakeholder alternative is itself a real accountability system — or mostly rhetoric — is the converse question, taken up in full in Is “stakeholder capitalism” real?.
Where this leaves us
Both sides have now won something, and neither has won everything. The critics are right about the defects: externality-dumping and hold-up are real. The defenders are right about the cure: shareholder primacy is the only doctrine with a working accountability mechanism, abandoning it invites the managerialism its own critics feared, and the short-termism part of the indictment is overstated — Roe and Fried have the data. So notice what neither side gets to claim. The critics don’t get to claim that real defects justify scrapping the doctrine. The defenders don’t get to claim that Friedman was simply right — externality-dumping and hold-up don’t disappear because the accountability mechanism is elegant. The question the verdict has to answer is the one the counter-counter just opened: if the defects are real and the accountability mechanism is worth keeping, what actually fixes the defects? The converse half — whether the stakeholder alternative is a real accountability system — is settled in Is “stakeholder capitalism” real?.
So shareholder primacy has real defects and its accountability mechanism is worth keeping. That points to a specific kind of answer — not “keep it” and not “scrap it,” but “fix the defects from outside.” The question is whether the outside fixes actually exist. They do — and the critics have mostly been aiming at the wrong target.
The verdict: real defects, mostly fixed externally
“If a firm pollutes, the answer is to make it pay for the pollution — not to rewrite the corporation’s charter. The problem isn’t that managers serve shareholders. The problem is that the price of dumping on everyone else is zero.”
— the reform-economist’s reframe of the corporate-purpose debate
The cross-partisan critics agree on the diagnosis and reach for the same cure: re-charter the corporation, mandate stakeholder boards, dethrone the doctrine. And that cure aims at the wrong target. The defects of Stage 2 are real, but each one has an address — and the address is not the corporation’s charter. It is the unpriced externality, the captured market, the broken labor law. Fix those, and you keep the one thing the doctrine does well.
The synthesis is a mapping: each real defect to its real fix, and every fix is something done to the firm’s environment rather than to its objective. The logic is the externality-internalization logic — price the cost the firm was dumping, and a shareholder-value-maximizing firm internalizes it automatically, because now it shows up on the firm’s own ledger. You don’t need to change what the firm maximizes; you change what maximizing costs.
Externality-dumping → price the externality. A carbon tax or Pigouvian regulation makes the firm pay for what it emits; the dumping stops not because the charter changed but because the cost is now on the bill. The carbon-pricing case at depth is Should we put a price on carbon?. Market-power-driven cost-dumping → antitrust, the instrument at the center of Do big tech companies have too much power?. Stakeholder-specific-investment hold-up → labor law, contract design, and possibly co-determination, which protect the specific investment the residual claimant would otherwise expropriate; the distributional stakes are in Is inequality a problem economics can solve?. Marginal short-termism → securities-market structure reform — disclosure cadence, holding-period tax treatment.
“Mostly external” is doing real work — it is not “do nothing to governance.” Targeted, accountability-preserving governance reforms belong in the fix: long-term-incentive pay that lengthens the manager’s horizon, narrow fiduciary-duty adjustments, a board seat for a major specific-investment stakeholder. What these share is that they keep the accountability metric intact while curing a specific defect. What they are not is federal re-chartering or a diffuse balance-everyone mandate, which dissolve the metric. The synthesis — the defects are real and the accountability mechanism is the doctrine’s genuine virtue — lives in the institutional-economics chapter, and the externality-internalization logic in the market-failures chapter.
“The problem isn’t that managers serve shareholders. The problem is that the price of dumping on everyone else is zero.”
— the reform-economist’s reframe
Is the fix external policy, not a new corporate purpose?
The layered verdict: shareholder primacy has real, specific defects — but the fix is external policy plus targeted, accountability-preserving governance reform, not abandoning the doctrine. Does that read as honest analysis, or as a dodge?
Fix it from outside, or change the doctrine?
“Every defect the critics name has a concrete external fix that keeps the accountability mechanism intact. Price the carbon, break the monopoly, fix the labor law, reform the disclosure cadence. The corporate-purpose statement fixes none of them.”
— the external-fix / measured-reform position
The measured-reform voice argues the synthesis at full strength before the calibration. Its claim is precise: there is a one-to-one map from each Stage-2 defect to an external instrument, and each instrument cures the defect by changing the firm’s costs rather than its objective — so the accountability metric survives. Add targeted, accountability-preserving governance tweaks at the margin, and the defects shrink without the cure becoming a new disease. The position is not “shareholder primacy is fine”; it is “the defects are real, and here is the toolkit that fixes them without throwing away the one thing the doctrine does well.”
“External fixes are captured and slow. The carbon price never passes, antitrust is asleep, labor law hasn’t moved in forty years. If the outside machinery is broken, the only lever left is the doctrine itself.”
— the strong-critique holdout
The holdout makes the serious version of the populist case, and it has a real lineage: the financialization critique that revived after 2008, sitting alongside Piketty’s inequality data, the market-power renaissance, and the broader pluralist turn in economics. Its argument is that the external toolkit is politically dead, so structural change to the doctrine is the only thing that moves. The counter-counter holds the line: co-determination and targeted board reform are part of the fix — that is the “mostly external” caveat doing its work — but federal re-chartering and a diffuse balance-everyone mandate dissolve the accountability mechanism for the managerialism the critics’ own ancestors feared, and the converse walkthrough shows the diffuse alternative isn’t a real accountability system anyway. The home of that post-2008 pluralist critique is the modern-pluralism chapter of the economic-thought book.
The verdict
Shareholder primacy has real, documented, specific defects — externality-dumping is real wherever externalities are unpriced, stakeholder-specific investments are under-protected, and short-termism exists at the margin, though Roe and Fried show its pervasiveness is overstated. So it is a problem in specific, identifiable ways. But it remains the doctrine with the clearest accountability mechanism, and the genuine fixes are mostly external — externality pricing, antitrust, labor law, securities-market reform — complemented by targeted, accountability-preserving governance reform, not abandoning the doctrine for an unaccountable balance-everyone mandate. The cross-partisan critics are right about the diagnosis and mostly wrong about the cure: they aim at the doctrine when they should aim at the unpriced externalities, the captured markets, and the broken labor law. And this dovetails with the converse question: the status-quo critique is partly valid and the proposed alternative isn’t a real accountability system, so the fix is external policy plus targeted governance reform — which is exactly the case made in Is “stakeholder capitalism” real?.
Where this leaves us
We started with an indictment that Elizabeth Warren and Marco Rubio could both sign: shareholder primacy broke the link between corporate profit and shared prosperity. Each stage that followed tested it. The critique, taken as serious economics rather than populism, turned out to have real teeth — externality-dumping is genuine wherever externalities are unpriced, stakeholder-specific investments are exposed to hold-up, and short-termism bends some managers at the margin. The defense, taken at full strength, also held: shareholder primacy is the only corporate-governance doctrine with a working, enforceable accountability mechanism, abandoning it for a diffuse mandate invites the unaccountable managerialism the critics’ own intellectual ancestors feared, and the most dramatic charge — systemic short-termism — is the one the aggregate data supports least. The verdict lives in the seam between those two findings.
The honest answer is calibrated. Shareholder primacy has real, specific defects — so it is a problem — but they are best fixed by external policy (externality pricing, antitrust, labor law, securities reform) plus targeted, accountability-preserving governance reform, not by abandoning the doctrine for an unaccountable balance-everyone mandate. The critics aimed at the charter when they should have aimed at the unpriced externalities, the captured markets, and the broken labor law. And this is only half the corporate-purpose debate. This walkthrough asked whether the status quo is a problem; its companion, Is “stakeholder capitalism” real?, asks whether the proposed alternative is a genuine accountability system — and finds it mostly is not. The two verdicts dovetail: the critique of the status quo is partly valid and the alternative isn’t real, which is precisely why the fix is external policy plus targeted reform, and not the diffuse alternative. Neither half makes sense alone; together they are the whole picture.
