Market Failure #1 PUBLIC GOODS Why doesn’t the free market provide them? There is little opportunity to earn profit. Why NOT? Individuals benefit without paying. 3

How do we decide how many public goods we need? 4

Can the government… 1. Prevent wild fires in San Diego forever? 2. Ensure that no one ever speeds on the freeway? 3. Create a research station on Mars? 4. Stop pollution from fossil fuels? 5. Completely stop illegal immigration? 6. Make sure everyone in the US has a job? YES! But the costs outweigh the benefits. How does the government decide how many public goods to provide?

How does the government determine what quantity of public goods to produce? They use Supply and Demand for Public Goods. The Marginal Social Benefit of the good determined by citizens willingness to pay. Supply of Public Goods. The Marginal Social Cost of providing each additional quantity. Video: Dam Tragedy
