Why managers optimize for themselves instead of shareholders — the structural tension

Ryan Castillo & Jordan Hale

The principal-agent problem — where professional managers control firms they don't own — has been documented since Berle and Means in 1932 and formalized by Jensen and Meckling in 1976. Residual loss persists even after monitoring and bonding costs are paid. After 90 years of evidence, this isn't a governance flaw awaiting a fix; it's a permanent structural cost of the dispersed public corporation.

In large publicly traded corporations, ownership is typically dispersed across thousands of shareholders while day-to-day decision-making authority is concentrated in a small group of professional managers and executives.

About this episode

There's a tension built into every publicly traded company: the people who own it and the people who run it are not the same people, and their interests don't naturally align. That's not a new observation — Berle and Means wrote about it in 1932. What's striking is how little has changed since. This episode works through why. It starts with Jensen and Meckling's 1976 framework, which put a name and a cost structure on the principal-agent problem: monitoring costs, bonding costs, and a residual loss that persists even after you've done everything right. The manager is inside the firm every day; the board reviews a quarterly deck. That information gap is where discretion lives. From there, it gets into what managers actually do with that discretion — empire-building, manager-specific investments that make replacement genuinely costly — and then the thing that really complicates the picture: the equity compensation that was engineered to fix all of this. Bebchuk and Fried's 2003 work showed how option grants became an extraction mechanism rather than an alignment tool, because the people setting the terms of those grants weren't bargaining at arm's length. The episode doesn't land on a clean solution, because the evidence doesn't support one. Board independence has decades of empirical research behind it and mixed results at best. What it does land on is a reframe: this might not be a governance failure waiting for the right patch. It might just be the permanent, structural cost of the dispersed ownership model — one we keep calling a flaw instead of a feature.

Frequently asked

What is the principal-agent problem in corporate governance?

The principal-agent problem arises when professional managers control a firm's decisions while shareholders bear the financial consequences. Because managers' incentives differ from shareholders', they may pursue empire-building or entrenchment rather than value creation. Jensen and Meckling formalized this in 1976, identifying monitoring costs, bonding costs, and an irreducible residual loss.

What are agency costs and why do they persist even with oversight?

Agency costs, per Jensen and Meckling's 1976 framework, fall into three categories: monitoring costs paid by shareholders, bonding costs paid by managers, and residual loss — the value gap that remains even after both. Residual loss persists because monitoring is never complete; managers have daily access to information that boards receive only quarterly.

Did stock options fix the principal-agent problem?

Stock options were designed to align CEO incentives with shareholder value but failed, according to Bebchuk and Fried's 2003 Journal of Economic Perspectives analysis. Because CEOs influence the compensation committees that set option terms, equity grants reflected managerial power rather than arm's-length bargaining, turning the intended solution into an extraction mechanism.

What is managerial entrenchment and how do managers use it?

Managerial entrenchment, documented by Shleifer and Vishny in 1989, occurs when executives make firm-specific investments — building organizational structures around their own knowledge and relationships — so that replacing them becomes genuinely costly. Managers also deploy poison pills and staggered boards to block hostile takeovers that would otherwise discipline underperforming leadership.

Is the shareholder-manager conflict a solvable governance problem?

The shareholder-manager conflict is not a solvable governance failure but a permanent structural cost of the dispersed public corporation model. Berle and Means identified it in 1932, Jensen and Meckling quantified it in 1976, and board independence reforms have produced mixed results at best. Ninety years of evidence suggests residual loss is the price of admission, not a fixable flaw.

Jordan Hale: Bebchuk and Fried. That's where I kept landing. Because they document how equity compensation — the thing we literally engineered to fix this problem — became the main way executives drain money out of the company instead. Like, the solution became the extraction tool. That broke my brain a little.

Ryan Castillo: Right, but before we get there — how does a situation even exist where that's possible? Walk me back.

Jordan Hale: Yeah, no, that's the right question. You know, it's almost — imagine you hire a house-sitter. You hand them the keys, you leave town. They have all the access. You have the deed. And their incentives? Not the same as yours.

Ryan Castillo: That's exactly the structure. Thousands of shareholders own the company, a small group of professional managers make every actual decision. Berle and Means named this in 1932 — effective control had already passed from owners to managers before anyone had a framework for it.

Jordan Hale: Wait — 1932? And then Jensen and Meckling are formalizing this in 1976 as the principal-agent problem, and we're still here talking about it. Like, we've known about this for almost a hundred years and it's just... still happening?

Ryan Castillo: That's the knowledge gap that should bother everyone.

Ryan Castillo: Jensen and Meckling put a number on why. 1976 paper — they break agency costs into three buckets. Monitoring costs: what shareholders spend trying to watch managers. Bonding costs: what managers spend trying to prove they're trustworthy. And then residual loss — the gap that persists even after you've done both. Even after you've paid for all of it, value still leaks.

Jordan Hale: Wait — so even in the best-case scenario there's still loss baked in?

Ryan Castillo: Built in. Because the monitoring can never be complete. The manager is inside the firm every day. The board gets a slide deck once a quarter. That information gap — that's where the discretion lives, and discretion is the thing you're trying to control.

Jordan Hale: And what do they actually do with that discretion? Like, in practice — what's the move?

Ryan Castillo: Empire-building. Firm size correlates with compensation, prestige, power — so you grow the firm. Not because it creates value, because it makes you bigger. And Shleifer and Vishny documented something even sharper in 1989: managers make manager-specific investments — they wire the organization around their own knowledge, their own relationships — so that replacing them becomes genuinely costly. You're not just firing a bad CEO, you're unplugging the machine.

Jordan Hale: Wait, no. That's the part that gets me. You know, there's a pension fund manager in Ohio right now whose retirement is sitting in a company where the CEO just greenlit a two-billion-dollar acquisition that analysts are openly calling value-destructive. But her options vest in three years, so... she doesn't actually care yet. And that pension manager can't do anything. Isn't that exactly what the governance tools are supposed to stop?

Ryan Castillo: That's exactly the gap equity-based compensation was supposed to close. Give the CEO stock options, now her upside is tied to share price, problem solved. That was the whole theory.

Jordan Hale: And then Bebchuk and Fried come in — 2003, Journal of Economic Perspectives — and they're like, actually no. The option grants became the extraction. Because who sets the terms of those grants? The compensation committee. And who has influence over the compensation committee? The CEO.

Ryan Castillo: Managerial Power Theory. Pay reflects power over the board, not arm's-length bargaining.

Jordan Hale: And then — I mean, this is the part that actually unsettled me — they use those same packages to defend themselves. Poison pills, staggered boards. The equity compensation created the war chest to block the very takeover threat that was supposed to discipline them if the equity compensation failed.

Ryan Castillo: Hold on. That's the market for corporate control argument completely inverted.

Jordan Hale: Right! So what does Fama say in 1980 — competitive managerial labor markets handle this through reputation, through monitoring. But wait, you can't monitor what you can't see. The information asymmetry that creates the agency problem is the same thing preventing the market from seeing clearly enough to discipline anyone. That's... circular.

Ryan Castillo: Yeah, I'll concede the circularity. And board independence was supposed to be the patch — independent directors, no financial ties to management. Decades of empirical research. Results: mixed, at best.

Ryan Castillo: Look, I think the frame is wrong. We keep calling it a failure — broken governance, flawed tools. But Berle and Means described this in 1932. Jensen and Meckling built the cost accounting for it in 1976. Residual loss isn't a temporary gap. It's... I mean, it's the permanent price. The dispersed public corporation model comes with that cost attached. We just keep refusing to name it that way.

Jordan Hale: Yeah. Yeah, that's — you know, that's actually what shifts something for me. It's not a problem waiting for the right patch. It's more like... the cost of admission we decided to stop reading the fine print on.

Ryan Castillo: Ninety years of evidence. That's probably enough to stop calling it a flaw.
