Who Watches the Managers?
In a large corporation, the people who own the firm (shareholders) are not the people who run it (managers). This separation creates the principal–agent problem: the principal (owner) hires an agent (manager) whose interests may diverge — empire-building, perks, quiet life — and whose actions the principal cannot fully observe.
Agency costs are everything this divergence burns: wasteful acquisitions, padded expenses, missed opportunities, plus the cost of all the monitoring designed to prevent them.
Corporate governance is the system of institutions that realigns the two:
- The board of directors: elected by shareholders to hire, monitor, and if needed fire executives. Independent directors — with no ties to management — are its credibility.
- Incentive pay: bonuses, shares, and stock options tie the manager's wealth to the owners' outcome. Powerful, but crude — badly designed bonuses reward short-term earnings games over long-term value.
- Transparency: audited accounts and disclosure duties shrink the information gap the agent hides behind.
- The market for corporate control: persistently mismanaged firms see their share price sag — inviting a takeover that replaces the management. The threat disciplines even managers who are never taken over.
Shareholder vs stakeholder models: the Anglo-Saxon tradition holds that managers serve shareholder value; the continental European tradition adds employees, creditors, suppliers, and community as legitimate claims. Most modern codes blend the two: create long-run value, and answer to those the firm's decisions touch.
The governance toolkit
| Mechanism | How it realigns interests |
|---|---|
| Board of directors | Hires, monitors, and can fire executives |
| Independent directors | Judgment without ties to management |
| Incentive pay | Ties manager wealth to owner outcomes |
| Audited disclosure | Shrinks the information gap |
| Takeover threat | Underperformance invites replacement |
Common pitfall: Treating incentive pay as a cure-all. A bonus tied to this quarter's earnings buys this quarter's earnings — including via cut R&D, channel stuffing, and accounting games. Incentives work exactly as written, not as intended.
