Common goods, also known as common-pool resources, refer to resources that are rivalrous (their use by one person diminishes their availability to others) but non-excludable (it is not feasible to prevent people from using them). These characteristics distinguish common goods from public goods, private goods, and club goods.
Characteristics of Common Goods
Rivalry
Rivalry in consumption implies that the use of a common good by one individual reduces the availability of the resource to others. For example, a fish caught from a lake cannot be caught by another person.
Non-excludability
Non-excludability means that it is challenging or impossible to prevent individuals from accessing the resource. For instance, anyone can go fishing in an open-access fishery without needing exclusive permission.
Types of Common Goods
-
Natural Resources:
- Fisheries
- Forests
- Groundwater basins
-
Shared Services:
- Public parks
- Urban roads
Challenges and Special Considerations
Overuse and Depletion
The main challenge with common goods is overuse, leading to depletion. This phenomenon is often described by the term “Tragedy of the Commons,” a situation where individuals, acting independently and rationally according to their self-interest, deplete a shared resource, even when it is clear that it is not in anyone’s long-term interest for this to happen.
Management Strategies
-
Regulation:
- Imposing quotas or permits, like fishing licenses.
- Establishing ownership rights or territorial user rights.
-
Community Management:
- Local governance and collective management strategies.
- Customary laws and community-based monitoring systems.
Historical Context
The concept of common goods has been discussed extensively in economic literature. The idea was notably articulated by economist Elinor Ostrom, who received the Nobel Prize in Economic Sciences in 2009 for her analysis of economic governance, particularly the commons. Ostrom’s work demonstrated that local communities could effectively manage common-pool resources without central regulation or privatization.
Applicability in Modern Economics
Common goods play a critical role in environmental economics and sustainability discussions. Effective management of these resources is crucial for ensuring that they remain viable for future generations. Policymakers and communities must navigate the balance between exploitation and conservation to sustainably manage common resources.
Comparisons with Related Terms

- Private Goods: Rivalrous and excludable (e.g., a sandwich, a car).
- Club Goods: Non-rivalrous but excludable (e.g., subscription-based services, private parks).

Summary
Understanding common goods is crucial in managing resources that are vital for both the present and future generations. Effective governance, through regulation and community management, is essential to mitigate the risk of overuse and ensure sustainability. The nuances between common goods and other types of resources highlight the importance of tailored economic policies and strategies for resource management.
