Why managers optimize for their interests, not shareholders' — the structural misalignment

July 29, 2026 · 15 min

Michael C. Vincent & Hope Sterling

The principal-agent problem, formalized by Jensen and Meckling in 1976, creates a permanent structural misalignment between managers and shareholders: managers pursue short-termism, empire-building, and risk-avoidance because information asymmetry lets them. No mechanism — stock options, boards, or employee ownership — has ever fully eliminated these agency costs.

The principal-agent problem is a foundational concept in corporate governance describing the structural conflict that arises when ownership and control of a firm are separated. Shareholders (principals) own the firm and delegate day-to-day decision-making authority to professional managers (agents).

About this episode

In 1932, economists Adolf Berle and Gardiner Means looked at the American corporation and documented something most people had been happy not to name: millions of shareholders own companies they can't watch, managed by people who don't own them. Nearly a century later, the separation is larger than it was then. This episode works through why that gap exists, what it costs, and why every mechanism designed to close it has fallen short. The conversation covers Jensen and Meckling's 1976 framework — monitoring costs, bonding costs, and residual losses — and walks through the three structural distortions that follow from information asymmetry: short-termism, empire-building, and the counterintuitive tendency of managers to take less risk than their shareholders actually want. It then examines what corporate America tried: equity-based compensation, board oversight, multiple large shareholders, and employee stock ownership plans. Each of these narrows the gap in one direction while widening it in another. The honest conclusion the episode arrives at isn't pessimistic, exactly — it's just precise. No combination of alignment mechanisms has been shown to fully eliminate agency costs. Dispersed ownership makes the scale of the modern public corporation possible. The agency costs are the price of that scale. Whether the bargain is worth it is a question we answer every quarter, by default, simply by not changing the structure.

Frequently asked

What is the principal-agent problem in corporate governance?

The principal-agent problem in corporate governance arises when shareholders (principals) hire managers (agents) who hold information shareholders cannot access. Jensen and Meckling formalized this in 1976: managers make decisions serving their own interests — job security, bonuses, reputation — rather than maximizing shareholder value, generating quantifiable agency costs every quarter.

What are the three main ways managers act against shareholder interests?

Managers structurally diverge from shareholder interests in three ways: short-termism (cutting investment to hit quarterly EBITDA targets), empire-building (adding headcount and acquisitions to increase their own job security and pay benchmarks), and excessive risk-avoidance (taking fewer calculated risks than shareholders want because their entire career is concentrated in one firm).

Do stock options solve the principal-agent problem?

Stock options do not solve the principal-agent problem. Research shows CEOs collect large payouts from sector-wide market gains they did not create — called 'pay for luck.' Options also create asymmetric incentives: managers capture unlimited upside but face no personal loss below the strike price, encouraging excessive risk-taking rather than eliminating misalignment.

Why can't a company's board of directors fully fix the agency problem?

Boards cannot fully fix the agency problem because CEOs often influence the nomination of their own directors, eliminating genuine independence before oversight begins. The agent being monitored effectively shapes the monitor. This means compensation packages, performance targets, and acquisition reviews are all set within a relationship already compromised at its source.

Can employee stock ownership plans (ESOPs) eliminate agency costs?

ESOPs reduce some dual agency costs and are linked to increased R&D investment, suggesting employees with equity stakes push for longer-horizon decisions. However, ESOPs also increase corporate risk-taking, with no clean verdict on whether that risk creates or destroys value. No combination of alignment mechanisms has been shown to fully eliminate agency costs.

Hope Sterling: Michael, I have been spiraling about something since I started prepping this week — like, genuinely could not sleep — and I need to just say it out loud.

Michael C. Vincent: Go on.

Hope Sterling: Berle and Means. 1932. These two economists literally look at the American corporation and write down — document, publish — that millions of shareholders own companies they can't actually watch, managed by people who don't own them. And then — nothing changes. We just kept building. We built it so much bigger.

Michael C. Vincent: Well. That's the story, isn't it.

Hope Sterling: But like — why? Why did nobody just, I don't know, fix the structure? Because they SAW it.

Michael C. Vincent: Because you can't fix what was never broken by choice. The 19th-century corporation outgrew its owners — that's not a policy failure, that's physics. The thing got too large for any one person to run. So you hired a professional. And the moment you did that, you created a gap: the Shareholders who own but don't manage, the Managers who control but don't fully own. That separation of ownership and control isn't a bug. It's the cost of scale.

Hope Sterling: Okay — okay so that's almost more unsettling? Because it means nobody's really the villain, it's just structural.

Michael C. Vincent: And Jensen and Meckling formalized exactly that in their 1976 paper — they called it the principal-agent problem. Shareholders are the Principals, Managers are the Agents, and there will always be agency costs from that gap: decisions made in the manager's interest, not the shareholder's, because the manager has information the shareholder simply cannot access.

Hope Sterling: The information thing — that's the part that hits me. Like, think about it this way: you hire someone to run your whole business while you're out of town. Every single day. You cannot watch the decisions they're making. Do you think their priorities and yours are going to line up perfectly? Ever?

Michael C. Vincent: That's the click. That gap — between what the Manager knows and what the Shareholder can see — that's the whole engine of this problem.

Hope Sterling: And we've known it since 1932, which is — I cannot with this — almost a hundred years, and the separation is literally larger now than it was then.

Michael C. Vincent: Larger than ever. That's not incidental. That's the thing worth sitting with today.

Hope Sterling: And that separation being bigger now means — like, the gap between what managers know and what shareholders can see is just wider, right? More information they can't reach?

Michael C. Vincent: That's exactly the machinery. Let me put you inside it. Picture a divisional CEO — October, three weeks before the quarter closes. Her bonus is tied to hitting EBITDA. She's sitting on a decision: cut the marketing budget, the number looks great, she hits the target. Or she protects the spend and next year's pipeline. She knows which one is better for the company. She cuts the budget.

Hope Sterling: But wait — isn't that just one person making a bad call? Like, one manager on one Friday?

Michael C. Vincent: That's the thing — it's not a bad call. It's information asymmetry doing exactly what it does. Shareholders cannot see whether that cut was strategically sound or self-serving. They see the EBITDA number. They don't see the marketing pipeline she just hollowed out. Jensen and Meckling called the losses from decisions like that residual losses — actual shareholder wealth, gone, because the agent's incentive and the principal's interest didn't line up. That's an agency cost. Not theoretical. Quantifiable.

Hope Sterling: Stop. So the cost isn't just like — paying someone to monitor her, it's the actual value that evaporated because of the decision she made?

Michael C. Vincent: Monitoring costs, bonding costs, and residual losses — Jensen and Meckling laid all three out. The residual loss is the piece nobody prices in when they're hiring the manager.

Hope Sterling: Okay and that — that scenario plays out in, like, thousands of firms simultaneously, every quarter.

Michael C. Vincent: Three times over, actually — because short-termism is only the first shape this takes. Empire-building is the second. A CEO adds headcount, buys a division that doesn't belong, expands the org chart — not because it creates value but because it makes him harder to fire and fattens the compensation benchmark. Researchers looked at S&P 1500 firms and found that selling, general and administrative costs — SG&A — rise faster when a company grows than they fall when it shrinks. Managers resist cutting resources they've accumulated. That asymmetry is the fingerprint of empire-building in the data.

Hope Sterling: Wait, the costs are literally sticky on the way down? Like, they won't let go of the headcount?

Michael C. Vincent: That's the word researchers use — sticky costs. And the third distortion, risk-avoidance, is actually — I mean, this one surprises people — it runs the opposite direction from what you might expect. A manager's entire career, reputation, human capital, is concentrated in one firm. So she's going to be more cautious than the shareholders want her to be, because shareholders hold diversified portfolios. They can absorb a calculated risk that fails. She cannot.

Hope Sterling: So shareholders are actually more comfortable with risk than the person running the company. That's — I genuinely did not think about it that way.

Michael C. Vincent: You see, the three of them together — short-termism, empire-building, risk-avoidance — these aren't personality failures. They're structural responses to the incentive environment. Any manager, put in that position, responds to those forces.

Hope Sterling: Which is — honestly more unsettling than if they were just greedy? Because there's no villain to remove. The incentive IS the structure.

Michael C. Vincent: And that's exactly where corporate America thought it had an answer. Because once you name the structure as the problem, the obvious move is — change the structure. Make the Manager an owner. And that's what happened in the 1980s and 1990s: stock options swept through corporate compensation packages as the dominant fix. Equity-based compensation, the idea being if the CEO's personal wealth rises and falls with the share price, the incentive gap closes.

Hope Sterling: Which — okay, I mean, that does sound elegant? Like, give them skin in the game, they start behaving like an owner.

Michael C. Vincent: It IS the right instinct. If Shareholders are the Principals and Managers are the Agents, and the whole problem is divergent interests — making the CEO a partial owner theoretically closes that gap. That's not bad reasoning.

Hope Sterling: But wait — I feel a 'but' coming and it's going to be bad.

Hope Sterling: Because the research on this is — okay, it's actually kind of devastating. There's this finding called 'pay for luck,' and it's exactly what it sounds like. The whole sector goes up, like, oil prices spike or interest rates drop or just the whole market has a great year, and the CEO cashes out options worth tens of millions of dollars for a stock movement that had nothing to do with anything they decided. They didn't generate that return. The macro did. But the payout is the same.

Michael C. Vincent: That's the quiet scandal of it.

Hope Sterling: And there's — wait, there's actually a weirder problem underneath that, which is the asymmetry of how options even work. A CEO gets options at, let's say, a strike price of forty dollars. Stock climbs to eighty, they print money. Stock falls to thirty, they just — don't exercise them. They're not losing anything below the strike price. So the downside literally does not exist for them the way it exists for Shareholders.

Michael C. Vincent: And that asymmetry does something specific to behavior.

Hope Sterling: It pushes them toward — like, picture a CFO in November, options vesting in six weeks. She's looking at a genuinely risky acquisition, the kind that could blow up spectacularly or double the stock price. A rational, fully-invested owner might pass. She swings. Because if it works, the options pay off enormous. If it tanks past her strike price, she's back to zero — which is exactly where she started. That's excessive risk-taking baked into the mechanism we designed to fix excessive risk-avoidance.

Michael C. Vincent: We didn't fail to design it correctly. We designed it exactly to tie CEO wealth to stock price. The part we didn't want to admit is that stock price and long-term enterprise value are not the same thing.

Hope Sterling: Stop. That's the whole — that's it right there.

Hope Sterling: And then there's this layer I find genuinely maddening — the Board of Directors is supposed to be the check on all of this, right, they design the pay packages, they're meant to represent Shareholders. Except CEOs often have real influence over who gets nominated to that board. So you've got an agency problem inside the solution to the agency problem. The people setting the compensation aren't necessarily designing it in Shareholders' interests.

Michael C. Vincent: And whether any monitoring mechanism — boards, ownership structures, anything — can actually close that loop permanently is the part we haven't gotten to yet, and I'll tell you, it does not get more reassuring.

Hope Sterling: And that's — wait, that's the part that's been nagging at me, because like, the Board is supposed to be the whole answer to this, right? They're the primary check. Independent directors, audit committees, the whole apparatus. But if the CEO is literally in the room when his own board nominees get discussed—

Michael C. Vincent: The independence is gone before the first meeting.

Hope Sterling: Which is — stop, that's insane. Like structurally. The Board of Directors exists specifically to monitor the CEO on behalf of Shareholders, and the CEO has a hand in picking who sits on it? That's not independence, that's — I don't even know what to call that.

Michael C. Vincent: You see, it's not a scandal in the tabloid sense. It's a structural recursion. The agent being monitored shapes the monitor. So when that board designs a compensation package, sets performance targets, decides whether to challenge a bad acquisition — the relationship is already compromised at the source.

Hope Sterling: Okay but — I mean, are there alternatives? Like, does anything actually partially work? Because I refuse to believe it's just a wall.

Michael C. Vincent: There are partial answers. Multiple large shareholders — not one controlling block, but several substantial ones — create what researchers call mutual monitoring. They watch management AND they watch each other. There's empirical evidence linking that structure to stronger firm innovation.

Hope Sterling: Wait, they police each other? That's — okay that's actually clever.

Michael C. Vincent: Until one of them gets large enough to extract private benefits — diverts contracts to a related firm, sells assets to themselves at a discount. Then you've traded the principal-agent problem for a principal-principal conflict. The controlling shareholder against the minority shareholders. Different shape, same cost.

Hope Sterling: Oh that's — yeah, okay, I walked right into that. What about ESOPs? Because I've seen that pitched as like, the humanizing fix — give employees actual equity, they care about the firm's health.

Michael C. Vincent: ESOPs do reduce dual agency costs — there's real research on that — and they're linked to increased R&D investment, which suggests employees with equity stakes genuinely push for longer-horizon bets. But they also increase corporate risk-taking, and that's — well, that's not cleanly good or bad. Higher risk-taking can create value or destroy it. No clean verdict.

Hope Sterling: So the answer to 'does anything fully work' is just — no. Like, not options, not boards, not multiple large shareholders, not ESOPs. None of them close it.

Michael C. Vincent: No combination of alignment mechanisms has been shown to fully eliminate agency costs. That's not a pessimistic reading — that's the finding. The Separation of Ownership and Control isn't a problem corporations can eventually patch. It's the operating system. Every mechanism is a renegotiation of the same tension, and the costs are a permanent economic drag on every public company, every quarter, right now.

Hope Sterling: Okay but — that's the thing. We came in here like, there's a problem, there's probably a solution someone found, we just need to find it. And what it actually is — every single mechanism, stock options, the Board of Directors, multiple large shareholders, ESOPs — they're not fixes. They're like, renegotiation terms. Different clauses in the same contract we keep signing.

Michael C. Vincent: That's precisely it. Berle and Means saw the contract in 1932. Jensen and Meckling priced it in 1976. And the price is still on the table.

Hope Sterling: Which means the question isn't — like, it was never 'when do we solve this.' It's whether dispersed ownership, millions of shareholders who can never actually watch what managers do, whether that bargain is worth the agency costs we're permanently paying. Every quarter. Forever.

Michael C. Vincent: And we keep renewing it. Because the alternative — owner-operators, concentrated control — can't produce the scale that a public corporation can.

Hope Sterling: I keep thinking about the thing I said at the top — that nobody fixed it after 1932 and that felt insane to me. But it's not insane, is it. It's just — that's the price tag. That's what the scale costs.

Michael C. Vincent: The separation of ownership and control isn't a wound waiting to heal. It's load-bearing.

Hope Sterling: That's — yeah. That's going to sit with me. Genuinely.

Michael C. Vincent: It's the right thing to sit with. Good conversation.
