For decades, economists have debated a stubborn question. Why does one country grow wealthy while its neighbor, sharing similar geography and climate, stays poor? In 2024, the Royal Swedish Academy of Sciences awarded the Nobel Memorial Prize in Economic Sciences to three researchers who offered one of the most compelling answers yet. Daron Acemoglu and Simon Johnson of the Massachusetts Institute of Technology, along with James A. Robinson of the University of Chicago, were recognized “for studies of how institutions are formed and affect prosperity”.
Their argument, in plain terms, is that the rules a society lives under, who owns property, who can start a business, who has a say in government, matter more to long term wealth than natural resources, climate, or even culture. Societies with weak rule of law and institutions built to benefit a narrow elite tend to stay poor, while societies with strong property rights and broad participation in economic life tend to prosper.
To test this idea, the trio turned to an unusual historical source. In their landmark 2001 paper, they examined the mortality rates faced by European colonists across different parts of the world centuries ago. Where colonizers could settle safely, they built institutions meant to protect their own long-term interests, courts, property rights, limits on arbitrary power. Where disease made settlement deadly, colonizers instead built extractive systems designed to pull out resources quickly rather than build anything lasting. Canada and Australia are often cited as examples of the first pattern. Congo and Peru are cited as examples of the second.
The striking part of their research is what came next. Those early institutional choices, made hundreds of years ago by administrators who never intended them to last, persisted long after independence. Legal systems, elite power structures, and economic rules tend to reproduce themselves across generations, which means a decision made in the 1600s can still shape a country’s income levels today (NTU Singapore). Acemoglu and Robinson expanded this argument in their book “Why Nations Fail,” describing a divide between what they call inclusive institutions, which protect property rights and allow broad participation in politics and markets, and extractive institutions, which concentrate power and wealth in the hands of a small group.
The theory has not gone unchallenged, and the debate is worth understanding on its own merits. Economist David Albouy published a detailed critique arguing that a large share of the original settler mortality data was applied inconsistently, borrowed from the wrong countries or mixing incomparable populations of soldiers, bishops, and laborers in ways that favored the researchers’ conclusions. Acemoglu, Johnson, and Robinson responded directly, defending their original data choices and arguing their results held up even under stricter versions of Albouy’s critique. Other economists have pushed a competing explanation entirely, suggesting that geography and disease burden affect a country’s productivity directly, separate from whatever institutions happened to get built there. Still others argue that education and skills, not abstract institutional rules, are the deeper cause of long-term prosperity, and that better institutions often follow from an educated population rather than the other way around.
None of this fully unravels the core finding, which remains among the most cited results in modern economics and helped reshape how development economists think about growth. What it does suggest is that no single factor fully explains why nations diverge economically. For business leaders and investors trying to understand which markets carry long term promise, this research offers a useful lens. Countries with reliable courts, enforceable contracts, and predictable rules for who owns what tend to attract the kind of patient capital that builds lasting industries, while countries where those rules can shift at the whim of whoever holds power tend to struggle to hold onto investment over time.
