The Political Scientist Who Debunked Mainstream Economics

“Picture a pasture open to all.”

For at least a generation, the very idea of the commons has been marginalized and dismissed as a misguided way to manage resources: the so-called tragedy of the commons. In a short but influential essay published in Science in 1968, ecologist Garrett Hardin gave the story a fresh formulation and a memorable tagline.

“The tragedy of the commons develops in this way,” wrote Hardin, proposing to his readers that they envision an open pasture:

It is to be expected that each herdsman will try to keep as many cattle as possible in the commons. Such an arrangement may work reasonably satisfactorily for centuries because tribal wars, poaching and disease keep the numbers of both man and beast well below the carrying capacity of the land. Finally, however, comes the day of reckoning, that is, the day when the long-desired goal of social stability becomes a reality. At this point, the inherent logic of the commons remorselessly generates tragedy. As a rational being, each herdsman seeks to maximize his gain. Explicitly or implicitly, more or less consciously, he asks, “What is the utility to me of adding one more animal to my herd?”

The rational herdsman concludes that the only sensible course for him to pursue is to add another animal to his herd. And another…. But this is the conclusion reached by each and every rational herdsman sharing a commons. Therein is the tragedy. Each man is locked into a system that compels him to increase his herd with- out limit—in a world that is limited. Ruin is the destination toward which all men rush, each pursuing his own best interest in a society that believes in the freedom of the commons. Freedom in a commons brings ruin to all.

The tragedy of the commons is one of those basic concepts that is drilled into the minds of every undergraduate, at least in economics courses. The idea is considered a basic principle of economics—a cautionary lesson about the impossibility of collective action. Once the class has been escorted through a ritual shudder, the professor whisks them along to the main attraction, the virtues of private property and free markets. Here, finally, economists reveal, we may surmount the dismal tragedy of a commons. The catechism is hammered home: individual freedom to own and trade private property in open markets is the only way to produce enduring personal satisfaction and social prosperity.

Hardin explains the logic this way: we can overcome the tragedy of the commons through a system of “mutual coercion, mutually agreed upon by the majority of the people affected.” For him, the best approach is “the institution of private property coupled with legal inheritance.” He concedes that this is not a perfectly just alternative, but he asserts that Darwinian natural selection is ultimately the best available option, saying, “those who are biologically more fit to be the custodians of property and power should legally inherit more.” We put up with this imperfect legal order, he adds, “because we are not convinced, at the moment, that anyone has invented a better system. The alternative of the commons is too horrifying to contemplate. Injustice is preferable to total ruin.”

Such musings by a libertarian-minded scientist have been catnip to conservative ideologues and economists (who are so often one and the same). They see Hardin’s essay as a gospel parable that affirms some core principles of neoliberal economic ideology. It affirms the importance of “free markets” and justifies the property rights of the wealthy. It bolsters a commitment to individual rights and private property as the cornerstone of economic thought and policy. People will supposedly have the motivation to take responsibility for resources if they are guaranteed private ownership and access to free markets. Tragic outcomes—“total ruin”—can thereby be avoided. The failure of the commons, in this telling, is conflated with government itself, if only to suggest that one of the few recognized vehicles for advancing collective interests, government, will also succumb to the “tragedy” paradigm. (That is the gist of Public Choice theory, which applies standard economic logic to problems in political science.)

Over the past several decades, the tragedy of the commons has taken root as an economic truism. The Hardin essay has become a staple of undergraduate education in the US, taught not just in economics courses but in political science, sociology and other fields. It is no wonder that so many people consider the commons with such glib condescension. The commons = chaos, ruin and failure.

There is just one significant flaw in the tragedy parable. It does not accurately describe a commons. Hardin’s fictional scenario sets forth a system that has no boundaries around the pasture, no rules for managing it, no punishments for over-use and no distinct community of users. But that is not a commons. It is an open-access regime, or a free-for-all. A commons has boundaries, rules, social norms and sanctions against free riders. A commons requires that there be a community willing to act as a conscientious steward of a resource. Hardin was confusing a commons with “no-man’s-land”—and in the process, he smeared the commons as a failed paradigm for managing resources.

To be fair, Hardin was following a long line of polemicists who projected their unexamined commitments to market individualism onto the world. As we will see later, the theories of philosopher John Locke have been widely used to justify treating the New World as terra nullius—open, unowned land—even though it was populated by millions of Native Americans who managed their natural resources as beloved commons with unwritten but highly sophisticated rules.

Hardin’s essay was inspired by his reading of an 1832 talk by William Forster Lloyd, an English lecturer who, like Hardin, was worried about overpopulation in a period of intense enclosures of land. Lloyd’s talk is notable because it rehearses the same line of argument and makes the same fanciful error—that people are incapable of negotiating a solution to the “tragedy.” Instead of a shared pasture, Lloyd’s metaphor was a joint pool of money that could be accessed by every contributor. Lloyd asserted that each individual would quickly deplete more than his share of the pool while a private purse of money would be frugally managed.

I mention Lloyd’s essay to illustrate how ridiculous yet persistent the misconceptions about the “tragedy” dynamic truly are. Commons scholar Lewis Hyde dryly notes, “Just as Hardin proposes a herdsman whose reason is unable to encompass the common good, so Lloyd supposes persons who have no way to speak with each other or make joint decisions. Both writers inject laissez-faire individualism into an old agrarian village and then gravely announce that the commons is dead. From the point of view of such a village, Lloyd’s assumptions are as crazy as asking us to ‘suppose a man to have a purse to which his left and right hand may freely resort, each unaware of the other’.” (...)

Paradoxically enough, the heedless quest for selfish gain— “rationally” pursued, of course, yet indifferent toward the collective good—is a better description of the conventional market economy than a commons. In the run-up to the 2008 financial crisis, such a mindset propelled the wizards of Wall Street to maximize private gains without regard for the systemic risks or local impacts. The real tragedy precipitated by “rational” individualism is not the tragedy of the commons, but the tragedy of the market.
