Elinor Ostrom: Governing the Commons

The first woman to win the Nobel prize in economics, who showed that communities can manage shared resources without either privatisation or government control.

Elinor Ostrom, born in Los Angeles in 1933, was a political scientist who in 2009 became the first woman to receive the Nobel prize in economics. She shared it with Oliver Williamson. Her work challenged a widely held belief about shared resources.

The tragedy of the commons

In 1968 the ecologist Garrett Hardin published “The Tragedy of the Commons”, arguing that when a resource like a pasture or fishery is shared, each user has an incentive to overuse it, leading to ruin. Many concluded that the only solutions were to divide the resource into private property or to put the government in charge.

What Ostrom found

Ostrom studied real communities around the world managing common-pool resources: forests in Nepal, irrigation systems in Spain and the Philippines, fisheries in Turkey, grazing lands in Switzerland and many more. She found that many communities had managed shared resources successfully for centuries through their own rules, without privatisation or central government control.

Her 1990 book Governing the Commons set out design principles shared by long-lasting systems, including:

Clear boundaries defining who can use the resource.
Rules suited to local conditions.
Users taking part in making the rules.
Monitoring by people accountable to the users.
Graduated penalties for rule-breakers.
Low-cost ways to resolve conflicts.
Recognition of the community’s right to organise by outside authorities.

Swiss mountain pastures

In the Swiss village of Törbel, farmers have shared high mountain pastures for centuries. Local rules, recorded in writing as early as the thirteenth century, limit how many cows each family can send to the common pasture in summer, based on how many it can feed through the winter. Ostrom used such cases to show that users themselves can prevent overuse.

Legacy

Ostrom’s work showed the value of careful fieldwork and of looking beyond simple models. It has influenced policies on forests, fisheries, water and even shared digital resources. She emphasised that there is no single solution: what works depends on local conditions.

Thinking shared resources are always doomed

Hardin's tragedy is real in some cases, especially where users cannot communicate or enforce rules. But Ostrom showed many communities avoid it through well-designed local institutions. Overuse is a risk, not an inevitability.

Key takeaways

Elinor Ostrom became the first woman to win the Nobel prize in economics in 2009.
She challenged the idea that shared resources must be privatised or state-controlled.
Many communities manage common-pool resources successfully with their own rules.
Her design principles describe features of long-lasting community management.
