Why Some Countries Stay Poor: The Institutional Economics Answer

Why is Norway rich and Niger poor? Why did South Korea transform from a country poorer than Ghana in the 1960s into one of the world's most advanced economies by the 2000s, while Ghana remained stuck? Why did Botswana grow rapidly after independence while the Democratic Republic of Congo, sitting on one of the world's largest deposits of mineral wealth, descended into chronic conflict and poverty?

These questions occupied development economists for most of the 20th century. The answers proposed ranged from geography (tropical climates are bad for productivity) to culture (some societies have values that promote economic growth and others don't) to colonial history. The institutional economics answer, which has become the dominant framework over the past three decades, is both more tractable and more unsettling than any of these.

What Institutions Are

In economics, institutions are the rules of the game: the formal and informal rules that govern how people interact, exchange, and cooperate. They include property rights (can you securely own land and assets?), contract enforcement (will courts uphold agreements?), rule of law (do the rules apply to everyone, including the powerful?), and political institutions (who makes decisions and how).

Daron Acemoglu and James Robinson, who won the Nobel Prize in Economics in 2024 for their work on institutions and prosperity, make a distinction between extractive and inclusive institutions. Extractive institutions are designed to transfer wealth from the many to a narrow elite. Inclusive institutions create broad property rights, rule of law, and political participation that allow a wider share of the population to invest, innovate, and participate in economic life.

South Korea vs. North Korea: The Natural Experiment

The most striking natural experiment in institutional economics is the Korean peninsula. In 1945, North and South Korea shared the same culture, the same language, the same geography, and roughly the same level of economic development. By 2023, South Korea's GDP per capita was approximately USD 33,000. North Korea's was estimated at under USD 1,800, though reliable data is scarce.

The difference between these two outcomes is almost entirely institutional. South Korea developed (imperfect and at times authoritarian, but eventually) inclusive economic institutions: secure property rights, a functioning legal system, an education system that expanded broadly, and political reforms that increased accountability over time. North Korea built extractive institutions that concentrated economic and political control in an elite and suppressed the innovation and investment that create sustained growth.

The Colonial Origins of Institutional Divergence

Acemoglu, Johnson, and Robinson's landmark 2001 paper in the American Economic Review made the historical case for institutions using a clever empirical strategy. They observed that European colonisers built very different institutions in different places, depending on whether they intended to settle or simply extract. In places where the disease environment was hostile to European settlement (tropical Africa, parts of Latin America), colonisers built extractive institutions: minimal property rights, concentrated power, resources channelled to the colonial centre. In places where Europeans settled in large numbers (North America, Australia, New Zealand), they built institutions that protected property rights and provided some degree of rule of law, because the settlers needed those protections themselves.

The institutions built during the colonial period persisted after independence. Countries that inherited extractive colonial institutions tended to remain poorer than those that inherited more inclusive ones. This is not destiny: South Korea and Botswana both inherited relatively poor institutional starting points and improved them through deliberate policy. But the correlation between colonial institutional quality and current economic development is strong and has proven robust across many different empirical tests.

Key Institutional Quality Indicators: A Comparison

The World Bank's Worldwide Governance Indicators measure six dimensions of institutional quality. Here is how a selection of countries compare on rule of law (scored from -2.5 to +2.5, higher is better):

Denmark: +1.93 Singapore: +1.84 South Korea: +1.10 India: +0.05 Nigeria: -0.88 Democratic Republic of Congo: -1.42 The correlation between rule of law scores and GDP per capita across countries is one of the strongest relationships in empirical economics. It doesn't prove causation perfectly, but the mechanism is clear: when property rights aren't secure and contracts aren't enforced, investment falls, long-term economic decisions become impossible, and growth stagnates.

Why Institutions Are Hard to Change

If inclusive institutions produce growth and extractive ones produce poverty, why don't countries simply switch? The answer is that institutions are not just economic arrangements. They are political ones. Extractive institutions, by definition, benefit the people who control them. Those people have both the incentive to preserve them and, because they benefit from the existing arrangement, often the political power to do so.

This is why institutional change tends to happen at moments of disruption: revolutions, independence movements, crises that break the hold of existing elites. It's also why external pressure (from international organisations, aid conditions, trade agreements) has a mixed record. Institutions that are imposed externally without the internal political coalition needed to sustain them tend not to last.

What This Means for Development Policy

The institutional economics framework has a specific and somewhat uncomfortable implication for development policy: there are no shortcuts. Injecting capital into a country with extractive institutions tends to enrich the elite that controls those institutions. Building roads in a country without rule of law tends to benefit whoever controls the roads. Aid and investment need institutional foundations to work.

This doesn't mean aid is pointless or that poor countries are beyond help. It means the hardest and most important work in development is building the institutional environment that allows everything else to compound. That is slower, less visible, and harder to measure than building a school or a road. It is also what the evidence suggests matters most.
