Resource Curse
The pattern in which countries rich in oil or minerals grow slower, govern worse, and fight more than countries with nothing valuable under the ground.
Countries that strike oil or find large mineral deposits tend to grow more slowly, govern worse, and fight more than countries with nothing valuable in the ground. Economists have been calling it the resource curse since the 1990s, and the reason it is worth a name is that it makes no obvious sense. A windfall ought to help.
Two different things are going on, and confusing them is the most common mistake.
Dutch disease
The first problem is mechanical. The name comes from the Netherlands after the huge Groningen gas field was found in 1959, and The Economist coined it in 1977. Exporting a resource brings in foreign currency, which pushes up the exchange rate, which makes every other export more expensive abroad. The resource industry also bids up wages and hires the best engineers. Manufacturing and farming shrink, and those are the sectors where a country accumulates skills. When the resource runs out or the price collapses, the industries that might have replaced it are already gone.
The politics of easy money
The second problem is the serious one. Resource income goes to whoever controls the territory and the export terminal. It does not have to be earned by a broad population, and three things follow.
A government funded by oil does not need to tax its citizens, and a government that does not tax does not have to bargain with anyone. The historical link between paying taxes and demanding a say runs in both directions. Oil states get the reverse: the money buys subsidies, patronage jobs, and a large security service.
Control of the state becomes the only prize worth having, which raises the stakes of every election and coup, especially where the resource is easy to steal and far from the capital.
And revenue swings wildly with world prices, so budgets are written in booms and slashed in busts. That is a terrible way to run schools, armies, or anything else.
The curse is not automatic
Norway and Nigeria found their oil within a few years of each other. Norway already had courts, a working tax office, and a parliament that could impose a rule on itself, so it put the money into a fund invested entirely abroad and allowed itself to spend only the expected return. Nigeria had a fragile federation just out of a civil war, and the oil became the thing to capture. By the mid-1970s oil was more than ninety percent of Nigeria's export earnings, and its politics had reorganized around who controlled the ministry.
That is the pattern in the research too. The early studies found resource exporters growing more slowly across the board; later work showed the effect depends heavily on what institutions existed before the discovery. Resources do not decide a country's fate. They make whatever was already there much bigger.
Why it is a geopolitical problem
Countries living off resource exports are fragile in a specific way: their stability depends on a price they do not control. The Soviet Union collapsed after a decade of cheap oil. Venezuela imploded after the 2014 price crash. Gulf reform programs speed up whenever the market looks weak for the long term. Anyone who can move the price, by producing more or by sanctioning a rival producer, is reaching directly into another government's budget.
The same test is about to be run again. Lithium, cobalt, copper, and rare earths are turning a new group of countries in Africa, South America, and Central Asia into resource exporters, with the same two mechanisms waiting for them.
