The structure of the problem
Benefits enjoyed by a whole group, such as clean air, union wage bargaining or the success of a protest, usually have the character of public goods: those who did not contribute cannot be excluded. Each individual therefore reasons, "If others do it, I can enjoy the benefit for free," and if everyone thinks this way, no one contributes and the common benefit disappears. This structure is the many-person version of the prisoner's dilemma, in which individually rational choices produce a collectively bad outcome, and it shares roots with Hardin's (1968) tragedy of the commons on the overuse of shared resources. Game theory calls these social dilemmas.
Olson's logic and classic solutions
Mancur Olson (1965) overturned the assumption that groups act whenever they share an interest. The larger the group, the smaller one member's effect on the outcome and the harder mutual monitoring, so free riding worsens. Small groups with concentrated interests, such as a particular industry, therefore organize more effectively than large groups with diffuse interests, such as consumers or taxpayers, which helps explain phenomena like regulatory capture. Olson's solution was "selective incentives," benefits or penalties applied only to members. Russell Hardin (1982) developed the logic in political philosophy, Thomas Schelling (1978) modeled tipping points beyond which participation spreads, and Marwell and Oliver (1993) analyzed the "critical mass" created by a few key contributors. Robert Axelrod (1984) showed that in repeated interactions, cooperation can evolve through strategies such as tit-for-tat.
Ostrom, experiments and current issues
Elinor Ostrom (1990) analyzed communities that had sustainably managed fisheries, forests and irrigation systems for centuries and showed that, without state control or privatization, design principles such as clear boundaries, participatory rule-making, monitoring and graduated sanctions can solve collective action problems; she received the 2009 Nobel Prize in economics. She later (1998) stressed trust, reciprocity and reputation as the core of cooperation, connecting to work on social capital. In public-goods experiments, people contribute substantially at first but gradually cut back (Ledyard, 1995), yet cooperation holds up when they can punish free riders, even at a cost to themselves (Fehr and Gächter, 2000). Today climate change is seen as a leading collective action problem requiring international cooperation (Barrett, 2003), and Bennett and Segerberg (2012) argued that social media enable "connective action" that links individuals without formal organizations.
FAQ
- How is free riding related to the collective action problem?
- Free riding is the individual behavior of enjoying benefits without contributing; the collective action problem is the group-level outcome when many people free ride and the common benefit is not realized.
- Is the problem smaller in small groups?
- According to Olson, yes. In small groups each contribution is noticeable, monitoring is easier and each member's share of the benefit is larger, so cooperation is relatively easier.
