- Define collective action problems
- Explain the free-rider problem
- Evaluate global governance efforts
Global Challenges
A virus doesn’t check passports. CO₂ doesn’t respect borders. The problems states most need to solve together are the ones cooperation finds hardest.
A collective action problem arises when everyone benefits from cooperation but each actor gains by free-riding — so rational self-interest produces collective failure, like overfishing a shared sea.
Key points
- Climate change: the ultimate collective action problem — emitters benefit, everyone pays.
- Free-riding: why cut emissions if others won’t? Treaties try to solve this.
- Pandemics showed both cooperation (vaccines in a year) and failure (vaccine hoarding).
- Global governance is weak but real: the UN, WHO, Paris Agreement.
The 1987 Montreal Protocol phased out CFCs — every country complied, and the ozone hole is healing. Proof that global cooperation can work when science is clear and substitutes exist.
Practice
CFCs had cheap substitutes and few producers; fossil fuels power whole economies with no easy substitute, and every country is involved.
Enjoying the benefits of others’ cooperation (e.g. a stable climate) without bearing the costs yourself.
- Borderless problems need cooperation anarchy resists.
- Free-riding is the core obstacle.
- The ozone treaty proves cooperation can succeed.
- Global governance exists — but remains fragile.
