Start here. If agency theory says what can go wrong, governance is the list of things that stop it. Split the list in two: internal mechanisms the firm designs itself (board, committees, pay, ownership, internal control) and external mechanisms the environment imposes (takeover threat, labour market, product-market competition, lenders, auditors, analysts, regulators). No single mechanism is decisive; they substitute for each other, which is why the same board structure looks effective in one country and useless in another.
In plain English
Plain English: owners cannot watch a manager all day, so they hire a small group of people to watch on their behalf — the board — and they arrange the manager's pay so that doing well for the company is also doing well for himself. Outside the company, competition, lenders and the risk of being bought or fired do some of the watching for free.
The advanced view
Advanced view: Adams, Hermalin & Weisbach (2010) survey board research and reach two conclusions worth carrying. First, boards perform two functions at once — advising and monitoring — and the structures that improve one often degrade the other, because information flows from the CEO to a board that may also have to discipline him. Second, almost every board variable is endogenous: firms choose their boards in response to their circumstances, so the correlation between independence and performance identifies a selection process, not a causal effect. Treat cross-sectional governance rankings with suspicion.
Internal mechanisms
Board composition
Independence, size, expertise, tenure, diversity of experience, foreign representation. Independence aids monitoring; insider knowledge aids advice.
Board process
Committees (audit, remuneration, nomination, risk), meeting frequency, quality and timing of information, executive sessions without the CEO, and a chair separate from the CEO.
Incentive design
Mix of salary, annual bonus, long-term equity, vesting horizon, performance conditions (relative TSR, ROIC, cash conversion), clawbacks and shareholding requirements.
Ownership structure
Concentration, identity of owners (family, state, foundation, institutional, PE), managerial stake, and share-class structure.
Internal control and reporting
Internal audit, delegation-of-authority limits, segregation of duties, whistleblowing — the plumbing of decision control.
External mechanisms
Market for corporate control
Underperformance depresses the price, invites a bidder, and costs the incumbent management their jobs. Blunted by anti-takeover devices and controlling owners.
Managerial labour market
Reputation is an asset. Managers who destroy value are priced accordingly for their next role, which disciplines behaviour without any contract.
Product-market competition
The strongest and most under-rated mechanism. Slack cannot survive intense competition; in a protected market bad governance is affordable for decades.
Creditors and covenants
Lenders monitor continuously, price risk, and impose maintenance tests. Leverage transfers monitoring to a professional who is paid to do it.
Auditors, analysts, media, regulators
Information intermediaries reduce asymmetry, and the threat of exposure changes behaviour before any enforcement happens.

Swedish and Nordic governance: control without ownership
The Swedish model solves the agency problem differently from the Anglo-American one. Instead of dispersed owners disciplining managers through markets, a small number of long-horizon controlling owners sit close to the company. Three features do the work.
First, the nomination committee is appointed by and composed of the largest shareholders, not by the board. Owners select the directors who will monitor the CEO, so the board's loyalty runs to owners rather than to management — the opposite of the classic US critique of a CEO-captured board.
Second, dual-class A/B shares. A shares typically carry ten votes, B shares one. A holder with 20% of the capital can control 60–70% of the votes, creating a wedge between cash-flow rights and control rights. Third, sphere ownership: the Wallenberg model runs through Investor AB and foundation ownership, holding significant positions in listed industrials for decades and staffing their boards from a shared network.
The trade-off is real in both directions. Concentrated, long-horizon control supports patient investment, fast decisions in a crisis and genuine strategic ownership — but it disables the market for corporate control, and the residual risk shifts from manager-vs-owner to controlling-owner-vs-minority: private benefits of control, related-party transactions, tunnelling and pyramiding. So in a Swedish situation the governance question is rarely 'is the CEO monitored' and usually 'are minority holders treated the same as the sphere'.
The A-share holder funds a fifth of the company and casts roughly three quarters of the votes. Everything about the governance analysis follows from that gap: takeovers are effectively impossible, the board answers to one owner, and minority protection has to come from law and disclosure rather than from the vote.
Measuring the wedge
Votes held = 10 × A shares + 1 × B shares Wedge = vote share − capital share Example: 2M A shares and 8M B shares → votes = 20M + 8M = 28M A holder owning all A shares: capital share = 2/10 = 20%, vote share = 20/28 = 71%, wedge = 51 points Control premium in a transaction reflects the value of the vote, not the cash flow
Must know cold
- ✓Internal vs. external mechanisms, with three examples of each, and the point that they substitute.
- ✓Boards both advise and monitor; independence helps the second and can hurt the first.
- ✓Board research is endogenous — firms choose boards, so correlation with performance is not causation.
- ✓Swedish specifics: owner-appointed nomination committees, A/B share wedges, sphere/foundation ownership.
- ✓Concentrated control replaces the manager–owner conflict with a majority–minority conflict.
Worked example — does the takeover threat discipline this firm?
Step 1 of 7
- 1A listed firm trades at an equity value of 4,000; an acquirer believes it is worth 5,200 under better management
Common pitfalls
- ×Scoring governance with a checklist. Mechanism quality is contextual; a checklist rewards form over function.
- ×Assuming independent directors are always better. They are less informed, and information is what monitoring runs on.
- ×Reading a Swedish company through a US lens. With a controlling sphere, the CEO-entrenchment story is usually the wrong one.
- ×Ignoring product-market competition as a governance mechanism because it is not in the annual report.
- ×Confusing control rights with cash-flow rights when computing per-share value in a deal.
Where this lands in strategy and in the room
Governance decides which recommendations are feasible. A break-up that a controlling foundation will never accept, a hostile approach where the target has 70% of the votes locked, a transformation that requires the board to fire the executives who designed it: all analytically sound, all undeliverable. Consultants who name the decision rights alongside the recommendation get taken seriously.
Exercises
Try each one on paper before revealing the worked solution.
Exercise 1
A company has 3M A shares (10 votes each) and 12M B shares (1 vote). A family holds all the A shares plus 1M B shares. Compute their capital and vote shares, and state the main governance risk.
Exercise 2
A structuring exercise. A CEO's bonus is 60% EPS growth and 40% revenue growth; the firm has just funded a large acquisition entirely with cheap debt and EPS rose 14% while ROIC fell from 12% to 8% against a 9% WACC. Structure the governance critique.
