CORE DEFINITION

When a public good (such as a park, national defense, or open-source software) is provided, it is impossible to exclude anyone from using it, even if they have not paid the cost. This leads rational individuals to choose not to pay while still enjoying the benefits, ultimately potentially resulting in no one providing the public good.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

A barrier to collective action. It explains why mechanisms such as taxes, membership fees, and mandatory contributions are needed to solve the supply problem of public goods. In open-source communities, labor unions, and environmental actions, mechanisms need to be designed to prevent free-riding behavior.

Anchor fast decisions

Once a public good is provided, it is non-excludable (difficult to exclude non-payers), so rational individuals choose not to pay (free-ride). If everyone does this, no one is willing to provide it, leading to a 'commons'-like supply failure. External mechanisms (taxation/coercion/membership) are needed to internalize the cost.

Tragedy of the Anticommons

The tragedy of the anticommons, proposed by American professor Heller in 1998, refers to a situation where resources that should be publicly owned are not fully utilized by society due to fragmentation and privatization of property rights. It is a derivative term from the tragedy of the commons. Contrary to the problem of overuse in the tragedy of the commons, the tragedy of the anticommons arises when there are many rights holders who impede each other's use of resources, leading to underutilization or even idleness, causing losses to social welfare.
