A free rider benefits from something without paying for it. The classic example is public broadcasting. Everyone can watch, but only some donate. If enough people free ride, the service collapses. The problem shows up whenever a good is non-excludable, meaning you cannot easily stop people from using it.

Free riding is a collective action problem. Each individual has an incentive to let others pay. If everyone reasons that way, the good is underprovided or not provided at all. National defense, clean air, and public parks all face this issue. So do small groups like a team project where one member does not contribute.

Solutions include taxes, mandatory fees, and social pressure. Governments often provide public goods directly because markets undersupply them. In smaller groups, monitoring and shared norms can reduce free riding. The problem is never fully solved. It is managed.

Examples

• Public broadcasting donations
• Union representation without dues
• Group projects with non-contributors
• National defense
