The passage

Read, then answer

The concept of the commons — resources shared by a community and managed collectively — has a long history and a surprisingly contentious one. In 1968, the ecologist Garrett Hardin published a paper called 'The Tragedy of the Commons,' arguing that any resource held in common would inevitably be depleted. His logic was simple: if each individual user gains the full benefit of consuming the resource but shares the cost of depletion with all other users, rational self-interest will lead every user to consume as much as possible. The cumulative effect of individually rational decisions is collective ruin.

Hardin's argument was enormously influential, providing intellectual justification for the privatisation of common resources and for enclosure movements. It was also, as the political economist Elinor Ostrom demonstrated in her landmark 1990 work, based on a faulty empirical premise. Ostrom studied hundreds of communities around the world that had successfully managed common resources — fisheries, pastures, forests, irrigation systems — for centuries without depletion. These communities had developed sophisticated systems of rules, monitoring, and sanctions that aligned individual incentives with collective sustainability.

Ostrom's insight was that the tragedy of the commons is not inevitable — it is the outcome of a particular institutional failure. Where communities have the autonomy to develop their own rules and the capacity to enforce them, commons can be managed sustainably. The real tragedy, she suggested, may be the destruction of these arrangements by privatisation and state control.

  1. Q1. Garrett Hardin's 'Tragedy of the Commons' argument holds that shared resources will inevitably be depleted because:

    1. Communities lack the technical knowledge to manage complex natural systems
    2. Each user gains the full benefit of consumption but shares the cost of depletion, making maximum consumption individually rational
    3. Shared resources are always underfunded relative to privately owned resources
    4. The state cannot effectively monitor the use of resources spread across large areas
    Show answer

    Answer: B. Each user gains the full benefit of consumption but shares the cost of depletion, making maximum consumption individually rational

    The passage explains Hardin's logic: 'if each individual user gains the full benefit of consuming the resource but shares the cost of depletion with all other users, rational self-interest will lead every user to consume as much as possible.'

  2. Q2. Elinor Ostrom's 1990 work challenged Hardin's argument by demonstrating that:

    1. Most communities are not rationally self-interested and prefer cooperation instinctively
    2. State ownership of common resources is always superior to community management
    3. Many communities had successfully managed common resources for centuries through locally developed rules and sanctions
    4. The tragedy of the commons only applies to fisheries, not to other types of common resources
    Show answer

    Answer: C. Many communities had successfully managed common resources for centuries through locally developed rules and sanctions

    The passage states: 'Ostrom studied hundreds of communities around the world that had successfully managed common resources... for centuries without depletion. These communities had developed sophisticated systems of rules, monitoring, and sanctions.'

  3. Q3. According to Ostrom, when does the tragedy of the commons actually occur?

    1. Whenever a resource is shared between more than a certain number of users
    2. When there is an institutional failure — when communities lack the autonomy or capacity to develop and enforce their own rules
    3. Only when the resource in question is a finite natural resource
    4. When governments fail to privatise resources before they are over-exploited
    Show answer

    Answer: B. When there is an institutional failure — when communities lack the autonomy or capacity to develop and enforce their own rules

    The passage states: 'the tragedy of the commons is not inevitable — it is the outcome of a particular institutional failure. Where communities have the autonomy to develop their own rules and the capacity to enforce them, commons can be managed sustainably.'

  4. Q4. Hardin's argument is described in the passage as having provided 'intellectual justification for the privatisation of common resources.' This suggests that:

    1. Hardin was employed by private interests who wanted to acquire common land
    2. His theoretical argument was used to support policy decisions that transferred commons into private ownership
    3. Privatisation of commons was already occurring and Hardin's work had no independent influence
    4. Academic papers are routinely co-opted by political interests to justify predetermined policies
    Show answer

    Answer: B. His theoretical argument was used to support policy decisions that transferred commons into private ownership

    The passage presents Hardin's argument as 'enormously influential, providing intellectual justification for the privatisation of common resources and for enclosure movements' — i.e., his theory was used as a rationale for these policy choices.

  5. Q5. What is the 'real tragedy' that Ostrom suggests may result from privatisation and state control of commons?

    1. That private owners will over-exploit resources even faster than communities would
    2. That communities will lose the motivation to engage in collective action
    3. That the sophisticated community-managed arrangements that sustainably governed commons for centuries will be destroyed
    4. That the state will lack the revenue to compensate communities for the loss of their common resources
    Show answer

    Answer: C. That the sophisticated community-managed arrangements that sustainably governed commons for centuries will be destroyed

    The passage states: 'The real tragedy, she suggested, may be the destruction of these arrangements by privatisation and state control.' These 'arrangements' are the community rules and institutions that had successfully managed the commons.

  6. Q6. The passage describes Hardin's argument as based on 'a faulty empirical premise.' The faulty premise is:

    1. That individual users are rational actors who maximise their own benefit
    2. That shared resources are always eventually depleted, when in fact many communities have managed them sustainably
    3. That the cost of depletion is shared equally among all users
    4. That privatisation is a reliable solution to over-exploitation of natural resources
    Show answer

    Answer: B. That shared resources are always eventually depleted, when in fact many communities have managed them sustainably

    Ostrom's empirical finding — that many commons had been managed sustainably for centuries — directly challenged Hardin's premise that shared resources will inevitably be depleted.
