Free Rider Problem
The tendency for individuals or countries to benefit from a shared resource or collective effort without contributing to its provision, leading public goods to be underprovided.
Definition
The free rider problem arises when people can enjoy the benefits of a good or service without paying for it — because exclusion is impossible or impractical — so too few contribute and the good is underprovided or not provided at all. It is the classic market-failure explanation for the under-provision of public goods.

Overview
What it means
Climate stability is a global public good: every country benefits from others' emissions cuts whether or not it cuts its own. This creates an incentive to free ride, which is why international climate agreements rely on collective commitments, transparency, and review rather than voluntary action alone. The same logic applies to shared fisheries, watersheds, and the atmosphere.
How it is used
The concept is used to explain the logic of carbon pricing, subsidy design, international environmental agreements, and collective management of common-pool resources.
Why it matters
Free riding is the core analytical reason environmental problems with diffuse benefits and concentrated costs persist, and it shapes the design of nearly every multilateral environmental mechanism.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.
Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and an editorial decision to attribute them.
Submitted reviews stay private until an editor decides whether to accept and attribute them.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
