Institutions as Rules

Institutions are the rules of the game in a society --- the formal laws, informal customs, and enforcement mechanisms that shape what people can and cannot do, and that explain why some economies thrive while others stagnate.

What is it?

Markets do not float in a vacuum. Prices cannot coordinate behaviour if nobody enforces contracts. Property cannot be exchanged if nobody agrees on who owns what. Trust cannot scale beyond a village if there are no courts to settle disputes. Underneath every functioning economy sits a layer of institutions --- rules, both written and unwritten --- that make economic life possible.

The economist who gave this idea its sharpest formulation was Douglass North, who defined institutions as “the rules of the game in a society” and spent his career showing that these rules matter more than natural resources, technology, or geography in explaining why some countries are rich and others are poor.1 North won the Nobel Prize in Economics in 1993 for this work.

Institutions include formal rules --- property law, contract law, bankruptcy law, constitutions, regulatory codes --- and informal rules --- customs, social norms, unwritten codes of honour, and cultural expectations about how business gets done. The formal rules are written in statute books. The informal rules live in how people actually behave. Both shape economic outcomes, and they interact: a formal law that contradicts deep informal norms will often be ignored, while informal norms can evolve to fill gaps that formal law does not cover.1

The Peruvian economist Hernando de Soto extended this insight in a specific direction: property rights. He argued that what makes something “capital” --- productive wealth that can be borrowed against, sold, inherited, or collateralised --- is not the physical thing itself but the legal title that says it is yours and that the state will enforce your claim.2

In plain terms

If the economy is a football match, institutions are the rules of the game --- offside, fouls, the size of the pitch, how many players per side. You can have the most talented players in the world, but without agreed rules and a referee to enforce them, you do not get a match. You get a brawl.

At a glance

How does it work?

1. North’s framework --- rules, players, and the game

Douglass North drew a sharp distinction between institutions (the rules) and organisations (the players). A constitution is an institution. A parliament is an organisation. A property law is an institution. A real estate company is an organisation. The rules define what the players can do; the players try to win within the rules --- and sometimes try to change the rules in their favour.1

North argued that this distinction matters because most economic analysis focuses on the players (firms, consumers, governments) and ignores the rules. But the same players will behave very differently under different rules. A business that innovates under strong property rights might pivot to bribery under weak ones --- not because the people changed, but because the incentive structure changed.1

Think of it like...

A chess game. The rules of chess (how pieces move, how you win) are institutions. The players and their strategies are organisations. Change the rules --- say, allow the queen to jump over pieces --- and the entire strategy landscape shifts, even though the same players are sitting at the board.

2. Formal institutions --- the written rules

Formal institutions are the rules that are written down, codified, and enforced by an authority (usually the state). The most economically important ones include:13

  • Property rights: the rules that define who owns what and how ownership can be transferred. Without clear property rights, people cannot trade, invest, or plan for the future --- because anything they build or accumulate could be seized.
  • Contract law: the rules that govern agreements between parties. If you and I agree that you will deliver 100 units by Friday and I will pay you on delivery, contract law is what makes that promise enforceable.
  • Bankruptcy law: the rules that determine what happens when someone cannot meet their obligations. Good bankruptcy law allows failure without catastrophe, encouraging risk-taking and innovation.
  • Courts and dispute resolution: the enforcement mechanisms that give formal rules their teeth. A property right that cannot be enforced in court is not really a right.

3. Informal institutions --- the unwritten rules

Not all rules are written down. In every society, a layer of unwritten expectations governs how people actually behave. These informal institutions include:1

  • Customs: “this is how we do business here.” In some cultures, a handshake is a binding commitment. In others, nothing is binding until a written contract is signed.
  • Social norms: expectations about fairness, reciprocity, and trustworthiness. A society where cheating on a business deal causes social ostracism has a powerful informal enforcement mechanism that supplements (or sometimes replaces) formal law.
  • Cultural codes: deeply held beliefs about work, wealth, authority, and obligation that shape economic behaviour in ways that formal rules cannot capture.

North emphasised that informal institutions change slowly --- over decades or centuries --- while formal rules can change overnight with a new law or revolution. This mismatch explains why institutional reform so often fails: you can rewrite the law books in a year, but you cannot rewrite the culture.1

Think of it like...

The difference between traffic laws and driving culture. The traffic law says the speed limit is 120 km/h. The driving culture in some places says everyone does 140 and the police do not enforce the limit. Which rule actually governs behaviour? Both --- but the informal one often wins.

4. Dead capital --- de Soto’s property rights argument

Hernando de Soto, in The Mystery of Capital (2000), asked a question that North’s framework alone could not answer: why does capitalism produce prosperity in some countries and fail in others?2

His answer was strikingly concrete. In developing countries, poor people often own enormous amounts of physical wealth --- houses, workshops, land, equipment --- but this wealth is legally invisible. The house was built without a permit. The land has no deed. The workshop is unregistered. Because this property exists outside the formal legal system, it cannot be used as capital: it cannot be mortgaged, sold on a formal market, used as collateral for a loan, or inherited through a legal process.2

De Soto estimated that the total value of property held but not legally titled in developing countries exceeded $9.3 trillion at the time of writing --- more than the total value of all companies listed on the stock exchanges of New York, London, and Tokyo combined.2

He called this dead capital: wealth that exists physically but is economically inert because the institutional infrastructure --- property registries, title systems, land surveys, legal recognition --- does not reach it.

5. Why institutions persist --- path dependence

North’s most unsettling insight is that bad institutions tend to persist. He called this path dependence: once a set of rules is established, it creates organisations and interest groups that benefit from those rules and resist change, even when the rules are clearly harmful to the broader society.1

For example, if an economy’s institutions reward resource extraction over production (as in many oil-rich states), the organisations that grow powerful under those rules --- extraction companies, allied bureaucrats, military elites --- will resist any institutional reform that threatens their position. The institutions created the organisations, and the organisations now defend the institutions. This feedback loop explains why some countries remain trapped in poverty despite abundant resources --- a phenomenon economists call the resource curse.3

Concept to explore

See embeddedness for Karl Polanyi’s deeper argument that markets themselves are embedded in social relationships and cannot be understood apart from the institutional and cultural contexts they operate within.

6. Transaction costs --- why institutions exist at all

North also provided the answer to why institutions exist in the first place: they reduce transaction costs. A transaction cost is any cost incurred in making an exchange beyond the price of the thing being exchanged --- the cost of finding a trading partner, negotiating terms, writing a contract, monitoring compliance, and enforcing the agreement if something goes wrong.1

In a world of zero transaction costs, institutions would be unnecessary. People could make and enforce agreements perfectly on their own. But in the real world, transaction costs are enormous. You do not know if the person selling you a used car is honest. You cannot monitor whether a contractor is doing quality work every hour of the day. You cannot personally enforce a contract across national borders.

Institutions exist to lower these costs. Property registries reduce the cost of verifying ownership. Contract law reduces the cost of enforcing agreements. Courts reduce the cost of settling disputes. Accounting standards reduce the cost of verifying a company’s finances. Each institution is, at root, a solution to a specific transaction-cost problem.1

Why do we use it?

Key reasons

1. It explains long-run prosperity differences. Why is South Korea rich and North Korea poor? Why did Western Europe industrialise before sub-Saharan Africa? The institutional view says: look at the rules. Countries with institutions that protect property, enforce contracts, and reward production tend to prosper. Countries with institutions that reward extraction, corruption, or loyalty to power tend to stagnate.13

2. It reveals why reform so often fails. Changing formal laws without changing informal norms and enforcement capacity produces laws that exist on paper but not in practice. The institutional lens explains why “just copy the successful country’s laws” has repeatedly failed as a development strategy.1

3. It connects economics to governance. If economic outcomes depend on rules, then the question of who writes the rules and for whose benefit becomes central. Institutional analysis bridges economics, political science, and law in a way that pure market theory cannot.3

When do we use it?

  • When comparing economic performance across countries and trying to explain why similar resources produce different outcomes
  • When evaluating policy reforms and need to assess whether the institutional infrastructure (enforcement, norms, capacity) exists to make the reform work
  • When designing systems (technological, organisational, or governmental) and need to think about the rules that will govern behaviour within the system
  • When analysing why a market is failing and suspect the problem is not in supply and demand but in the underlying rules (property rights, contract enforcement, regulatory capture)
  • When studying economic history and want to understand why some civilisations thrived and others collapsed

Rule of thumb

When an economy is struggling despite having resources, technology, and willing participants, the problem is usually in the institutions --- the rules are rewarding the wrong behaviour.

How can I think about it?

The operating system analogy

An institution is like an operating system for a society. The applications (businesses, markets, organisations) can only do what the operating system permits. A well-designed operating system --- clear file permissions, reliable memory management, consistent APIs --- lets applications run smoothly. A poorly designed one causes crashes, corruption, and lost data, no matter how good the applications are.

  • The operating system = institutions (the rules of the game)
  • Applications = organisations (firms, banks, courts, households)
  • File permissions = property rights (who can access what)
  • APIs = contract law (standardised ways for applications to interact)
  • System crashes = institutional failure (corruption, unenforceable laws, breakdown of norms)
  • Upgrading the OS = institutional reform (risky, slow, and you cannot do it while the system is running at full speed)

Just as you cannot fix a buggy application by rewriting it if the operating system is corrupt, you cannot fix a struggling economy by changing individual firms or markets if the institutional infrastructure is broken.

The board game analogy

Imagine two groups playing a board game. Group A has a complete rule book, a neutral referee, and everyone agrees on how the game works. Group B has a rule book, but the referee is a player’s cousin, some rules are secretly changed between turns, and one player can steal from the bank without consequences. Both groups have the same board, the same pieces, the same starting positions. But Group A will have a functional, competitive game, and Group B will have chaos.

  • The rule book = formal institutions (laws, constitutions)
  • How players actually behave = informal institutions (norms, customs)
  • The referee = enforcement mechanisms (courts, regulators)
  • A biased referee = captured or corrupt enforcement
  • Secretly changing rules = institutional instability
  • Stealing from the bank = extraction without accountability

North’s point is that the quality of the game depends more on the rules and the referee than on the talent of the players. De Soto’s point is that some players are not even allowed to play because their assets are not recognised by the rule book.
