- Increase by subsidizing
- Reach Eefficient
- The optimal level of pollution:
- If MB > MC, then reducing pollution is beneficial
- If MB < MC, then reducing pollution is damaging
- Cap and trade systems: limit pollution and reward low polluters (sell permits)
- Transaction costs: time and resources needed to reach an agreement and good delivery
- Private bargaining is the most efficient way if costs are low
- Rivalry: one person’s consumption excludes others from benefitting
- Excludability: only the paying individual/ owner can consume the resource
- Private good: rival and excludable
- Public good: non-rival ad non-excludable
- Freeriding: benefit from consumption without paying
- Common resource: rival and non-excludable
- The tragedy of the commons: society tends to overuse common resources
- Fixed with
- Property rights (easy to sue)
- Community norms and traditions of respect
- Laws to limit access
