Adverse selection, moral hazard, and the cost of rules

◈ 6 cards

The two forms information asymmetry takes, which mechanism answers each, and why the answer costs something.

Managers know more

The people who run a company always know more about it than the people who own it or lend to it. That gap is information asymmetry, and it is not the same thing as uncertainty — the future is uncertain for everyone, but asymmetry means one party already knows something the other does not. It shows up in two distinct forms, and the midterm expects you to tell them apart.

Adverse selection — hidden information

Lakehead Marine Corp. builds workboats and is listed on the TSX. In March its operations VP learns that its largest customer will not renew a contract worth a fifth of revenue. The market will not hear until the quarterly release in May. If the VP sells her shares in April, she is exploiting an information advantage — insider trading — and the buyer on the other side of that trade has been adversely selected: she would not have bought at that price had she known.

Adverse selection is about hidden information, and it damages markets before any single trade: if investors believe insiders routinely trade on what they know, they demand a discount on every share, or stop buying altogether. The remedy is to shrink the information gap — timely, standardised, audited disclosure, plus securities law that forbids trading on what has not yet been disclosed.

Moral hazard — hidden action

Now the second form. Lakehead's CEO has a bonus tied to reported profit. In the same year he books an aggressive estimate of warranty costs — low — and the profit target is met. Nobody can observe his effort or his judgement directly; the owners see only the number he chose to report. That is moral hazard: because the manager's actions are hidden, he can shirk, or bias the report that stands in for his performance.

The remedy here is different. Disclosure alone does not fix a biased estimate — the estimate is the disclosure. What answers moral hazard is governance: a board that appoints and can dismiss the manager, an audit committee that hires the auditor, and standards written so that the numbers managers are judged on are hard to manipulate. Module 5 is entirely about this machinery, and it grows from this seed.

Why public companies need more rules

Put the two together and the private-to-public axis of L1.2 explains itself. In a family company the owners are the managers; the asymmetry is small and the owners can walk into the plant. In a public company the owners are thousands of outsiders who cannot. Both forms of asymmetry are larger, so the mechanisms that reduce them are heavier: mandatory IFRS, an annual audit, continuous disclosure, an independent board. Canada's certification rule, NI 52-109, adds that the CEO and CFO must personally certify the annual and interim filings — fair presentation, and the design and evaluation of disclosure controls and internal control over financial reporting — a management certification, without the auditor attestation of controls that the US regime added after its own scandals.

What the rules cost

None of this is free, and a good written answer says so. Rules cost compliance — audit fees, systems, staff. They cost competitive information — a disclosed segment margin is read by rivals as well as by investors. They can cost timeliness, because verified information arrives later than unverified information. And they do not remove asymmetry; they reduce it. No single set of disclosures serves every user: an investor forecasting cash flows wants different information from a lender checking a covenant or a shareholder judging management's stewardship, and every standard is a compromise among them.

Two forms, two remedies: disclosure shrinks hidden information; governance disciplines hidden action.
