The Economist Who Explained Why Groups Fail

Here's a puzzle that shaped twentieth-century economics: Why do large groups of people with shared interests so often fail to act on those interests?

Think about it. Millions of consumers would benefit from lower prices. Millions of taxpayers would benefit from more efficient government. Millions of citizens would benefit from cleaner air. Yet these vast majorities routinely lose out to tiny, organized minorities—a handful of steel producers, a few hundred lobbyists, a small cluster of polluters.

Mancur Olson spent his career answering this question, and his answers changed how we understand politics, economics, and the rise and fall of nations.

From a North Dakota Farm to the Corridors of Power

Olson was born in 1932 in Grand Forks, North Dakota, to a family of Norwegian immigrants. He grew up on a farm near the tiny town of Buxton, right on the border with Minnesota. His given name, Mancur, traces back through Scandinavian immigrant communities to the Arabic name Mansoor—a small reminder of how culture travels in unexpected ways.

The trajectory of his education reads like an American success story in miniature. North Dakota State University. Then a Rhodes Scholarship to Oxford. Then Harvard for his doctorate in economics. Along the way, he served two years in the United States Air Force, where he taught economics at the Air Force Academy in Colorado Springs.

After stints at Princeton and in Washington as Deputy Assistant Secretary of Health, Education and Welfare, Olson landed at the University of Maryland in 1969. He stayed there for the rest of his life, building what would become one of the most influential bodies of work in political economy.

That life ended suddenly in February 1998. Olson collapsed outside his office after lunch, suffering a heart attack at sixty-six. He never regained consciousness. He's buried in the cemetery of his childhood church—a small Norwegian Lutheran congregation near the family farm in Buxton—alongside his infant son who had died years earlier.

The Logic of Collective Action

Olson's first book, published in 1965, carried a deceptively dry title: The Logic of Collective Action: Public Goods and the Theory of Groups. Don't let that fool you. The argument inside was explosive.

Before Olson, political scientists and economists generally assumed that groups of people with common interests would naturally organize to pursue those interests. Workers would form unions. Consumers would demand representation. Citizens would band together for change. This seemed obvious. It seemed logical.

Olson demonstrated it was wrong.

His insight was devastatingly simple. In a large group, any individual member captures only a tiny fraction of the benefit from collective action—but bears the full cost of participation. So the rational choice is to stay home. Let others do the work. Enjoy the benefits anyway.

Economists call this the free-rider problem. Olson showed it wasn't just an occasional nuisance but a fundamental barrier to large-scale organization.

Consider a union of a hundred thousand workers trying to negotiate higher wages. If the union succeeds, every worker benefits equally whether they participated in the effort or not. But each individual worker who attends meetings, walks picket lines, or pays dues bears real costs. The mathematically rational choice? Skip the meetings. Don't walk the line. Pocket the wage increase anyway.

Now multiply this calculation by a hundred thousand workers. The union collapses before it starts.

Small groups, Olson argued, don't face this problem as severely. In a group of ten, each member captures one-tenth of the collective benefit—enough to make participation worthwhile. And social pressure works. You can't hide in a small group. Everyone knows who's contributing and who isn't.

This is why small, concentrated interests routinely defeat large, diffuse ones. A hundred steel executives can organize to lobby for tariffs. They each stand to gain millions. But a hundred million consumers, each losing a few dollars to higher prices, will never organize effectively against them. The costs of organization far exceed any individual's share of the benefit.

Selective Incentives: How Groups Actually Form

If Olson's logic were the whole story, large organizations would be impossible. Yet unions exist. Professional associations exist. Political movements exist. How?

Olson's answer: selective incentives. Successful large organizations don't rely on collective benefits alone. They offer private goods—benefits available only to members.

The American Association of Retired Persons doesn't just lobby for Social Security. It offers insurance discounts, travel deals, and pharmacy programs. The American Medical Association doesn't just represent doctors politically. It provides journals, conferences, and networking opportunities. Labor unions don't just negotiate wages. They offer job security, grievance procedures, and sometimes health benefits.

Strip away these selective incentives, and membership would collapse. The collective action is almost a side effect—a bonus enabled by the private goods that actually motivate participation.

Sometimes the incentive is coercion rather than reward. Mandatory union membership, professional licensing requirements, trade association dues built into industry pricing—these force participation by making the costs of non-membership exceed the costs of joining.

Either way, Olson's point stands: collective action for collective goods doesn't happen spontaneously. It requires institutional machinery to overcome the free-rider problem.

The Rise and Decline of Nations

Seventeen years after The Logic of Collective Action, Olson published its ambitious sequel: The Rise and Decline of Nations. Where the first book explained why collective action fails, the second explored what happens when it succeeds—and the news wasn't good.

Remember those small, concentrated interest groups that can organize effectively? Over time, they accumulate. Cotton farmers form a lobby. Steel producers form a lobby. Labor unions in protected industries form lobbies. Each group succeeds in extracting special treatment: subsidies, tariffs, regulations that favor incumbents, licensing requirements that block competitors.

Individually, each policy might seem minor. Collectively, they strangle economic growth.

Olson called these organizations "distributional coalitions." They exist to redistribute wealth from the unorganized many to the organized few. And they have a ratchet effect. Once established, they're nearly impossible to dislodge. The beneficiaries fight fiercely to preserve their privileges, while the costs remain too diffuse for effective opposition.

This theory offered a provocative explanation for a puzzling economic pattern. Why did Germany and Japan grow so rapidly after World War Two? Olson's answer: the war destroyed their distributional coalitions. Cartels, guilds, entrenched lobbies—all swept away. The economies could start fresh, without accumulated barnacles of special interests.

Meanwhile, the victorious nations—Britain especially—retained their full complement of distributional coalitions. The British trade unions, professional associations, and industry cartels that survived the war continued extracting rents and blocking change. Economic sclerosis set in.

The theory also explained regional variation within countries. Why were the American South and West growing faster than the Northeast? Those regions had younger economies with fewer established interest groups. The Rust Belt's organized labor and entrenched industries became anchors dragging down growth.

Olson wasn't making a moral argument. He wasn't saying unions or industry associations were evil. He was making an analytical point: any stable society accumulates distributional coalitions over time, and these coalitions impose growing costs on economic dynamism. Only major disruptions—wars, revolutions, radical political changes—clear the accumulated debris.

This became known as the theory of institutional sclerosis. Just as arteries accumulate plaque that eventually restricts blood flow, societies accumulate interest groups that eventually restrict economic vitality.

Roving Bandits and Stationary Bandits

Olson's final book, Power and Prosperity, appeared in 2000, two years after his death. It pushed his analysis back to first principles: Why do governments exist at all? What determines whether they help or harm economic development?

His answer started with bandits.

Consider a roving bandit—a raider who sweeps through a territory, takes everything of value, and moves on. This bandit has no incentive to preserve anything. Why leave wealth behind for someone else to steal? The rational strategy is total extraction.

Roving bandits make settled economic life impossible. Farmers won't plant crops that will be stolen before harvest. Merchants won't accumulate inventory. No one invests. The economy collapses to subsistence.

Now consider what happens when one bandit becomes powerful enough to establish permanent control over a territory—a stationary bandit. This changes everything.

The stationary bandit's interests suddenly align, partially, with the population's. A warlord who expects to rule for years or decades wants the economy to grow. More wealth means more to extract through taxation. The stationary bandit now has incentives to provide basic order, protect property rights (from other bandits), and even invest in public goods like roads and irrigation.

This is the origin of government, in Olson's telling. Not a social contract. Not divine right. Not the general will. Just a bandit who decided to stay put.

But the stationary bandit's interests only partially align with the population's. The bandit still extracts as much as possible without killing the goose that lays golden eggs. Taxation stays high. Arbitrary confiscation remains a risk. Investment remains depressed because property rights remain insecure.

Democracy, Olson argued, represents the next step. When rulers depend on broad popular support, their incentives shift again. Policies must satisfy majorities, not just enrich the ruler. Property rights become more secure. Taxation becomes more efficient and less arbitrary. Public goods expand because majorities demand them.

The progression—from roving bandit to stationary bandit to democratic ruler—isn't inevitable. Plenty of societies remain stuck at early stages. But where the progression occurs, it explains growing prosperity.

The Puzzle of Autocratic Growth

Olson's framework helps explain some otherwise puzzling cases. Why do some autocracies achieve impressive economic growth while others collapse into poverty?

The key variable is the ruler's time horizon. An autocrat who expects to rule for decades behaves like a patient stationary bandit—extracting rents but also investing in the economy's productive capacity. Lee Kuan Yew's Singapore. Park Chung-hee's South Korea. Deng Xiaoping's China.

An autocrat facing imminent overthrow behaves like a roving bandit—grabbing everything possible before the end comes. Mobutu's Zaire. Mugabe's Zimbabwe. The extraction becomes total; the economy collapses.

This also explains why dictatorships often grow rapidly for a generation, then stagnate. The founding autocrat has a long time horizon and invests accordingly. But succession creates uncertainty. Will the next ruler honor existing property rights? Will the regime survive? As the founding generation ages, time horizons shorten and extraction accelerates.

Democratic institutions solve this problem by making time horizons effectively infinite. The regime persists regardless of which party wins the next election. Property rights remain secure across administrations. Investment can safely take the long view.

Building Institutions: The IRIS Center

Olson wasn't content to theorize. In 1990, he founded the Center for Institutional Reform in the Informal Sector—known as the IRIS Center—at the University of Maryland. Funded by the United States Agency for International Development, the center worked to translate his ideas into practical policy.

The mission was urgent. Communist regimes were collapsing across Eastern Europe and the former Soviet Union. These societies needed to transition from command economies to market systems—but market systems require institutional foundations that can't be created by decree.

Property rights matter little if courts can't enforce them. Contracts are meaningless without reliable adjudication. Free markets become predatory without rule of law. The IRIS Center worked on the institutional plumbing that makes capitalism actually function.

The center expanded beyond the former communist world into South America, Africa, and Asia. One early initiative: organizing the first conference on corruption in francophone Africa during the 1990s—a sensitive subject that few were willing to address openly.

Judicial independence became a central focus. Markets can't function if judges can be bought or bullied. But judicial independence requires more than constitutional provisions. It requires professional norms, adequate salaries, secure tenure, and political culture that respects court decisions even when they're inconvenient.

The IRIS Center continued operating after Olson's death, eventually folding into other University of Maryland programs. But its work influenced how development economists think about institution-building—less focus on getting prices right, more focus on getting institutions right.

The Calmfors-Driffill Hypothesis

Olson's work influenced economic theory in unexpected ways. Consider the puzzle of wage bargaining and unemployment.

Economists long assumed that centralized wage bargaining—where a single national union negotiates with employers—would produce worse outcomes than decentralized bargaining, where individual firms negotiate with their own workers. The logic seemed clear: monopoly unions would push wages above market-clearing levels, creating unemployment.

But the evidence didn't cooperate. Some countries with highly centralized bargaining—Sweden, Norway, Austria—had lower unemployment than countries with decentralized systems.

Lars Calmfors and John Driffill, building on Olson's logic, proposed an explanation. The relationship between centralization and economic performance isn't linear—it's U-shaped.

At one extreme, fully decentralized bargaining works well. Individual workers compete with each other; wages stay moderate; employment stays high. At the other extreme, fully centralized bargaining also works well. A national union that represents all workers must internalize the costs of excessive wage demands—unemployment that falls on its own members. This restrains demands.

The worst outcomes occur in the middle. Industry-level bargaining is concentrated enough to exercise market power but not encompassing enough to bear the full costs. The steel workers' union doesn't care if its wage demands cause unemployment in textiles. It pushes hard, and so does every other industry union. The result: wage-push inflation and structural unemployment.

This insight reshaped labor market policy debates, particularly in Europe.

Legacy

The American Political Science Association honors Olson through its annual Olson Award for the best doctoral dissertation in political economy. The University of Maryland established an endowed professorship in his name—the Mancur Olson Professor of Economics.

But his real legacy lives in how we think about politics and economics. Before Olson, analysts often assumed that shared interests automatically generate collective action. After Olson, we understand that organization is the exception, not the rule—and we ask what specific conditions and institutions make it possible.

His work also undermined easy optimism about democracy. Yes, democracy produces better outcomes than autocracy. But democratic polities still accumulate distributional coalitions that slowly strangle growth. Powerful interests still organize while diffuse majorities remain passive. The mechanisms of decline operate in democracies too—just more slowly.

Perhaps most importantly, Olson forced economists to take institutions seriously. Markets don't float in a vacuum. They require property rights, contract enforcement, predictable rules, and countless other institutional arrangements that economists once took for granted. Understanding how these institutions emerge, persist, and decay became central to development economics.

The farm boy from North Dakota, buried in a small Norwegian Lutheran cemetery near Buxton, had explained something fundamental about how societies work. And in doing so, he changed how we think about why some nations rise while others decline.
