1. Chapter 28 Presentation 2

2. Government Intervention in Externalities 1. Lawsuits- pay damages to the injured party or the fear of litigation persuades firms not to pollute 2. Direct Controls- legislation limiting an activity (fines/imprisonment) 3. Specific Taxes- levy taxes on causes of negative externalities (ie CFCs)

3. Subsidy A payment of funds (or goods/services) by a government, firm, or household for which it receives no goods/service in return

4. Government and Positive Externalities ***correcting for under-allocation 1. Subsidies to Buyers- ex discounts for mothers to get babies vaccinated 2. Subsidies to Producers- $$ given to doctors or clinics for giving vaccines 3. Government Provisions- provide the product as a public good (ex Polio Vaccine)

5. Tragedy of the Commons The tendency for commonly owned natural resources to be overused, neglected, or degraded because the common ownership gives nobody an incentive to maintain or improve them EX- air, rivers, lakes, street pollution -dumping toxic wastes instead of proper disposal

6. Fallacy of Consumption Each firm/individual thinks that their individual contribution to pollution is so small that it is of little or no consequence However, multiplied hundreds or thousands of times, this leads to mass pollution

7. Market for Externality Rights (Cap and Trade) A market in which firms can buy rights to discharge pollutants. The price of such rights is determined by the demand for the right to discharge pollutants and a perfectly inelastic supply **a pollution control agency determines the amount of pollutants that water/air can safely absorb

8. Market For Externalities D 2006 D 2016 S=Supply of Pollution Rights 500 750 1000 $100 $200 P 0 Q Price Per Pollution Right Quantity of 1-Ton Pollution Rights

9. Benefits of Market for Externalities Monetary reason for firms not to pollute Conservation groups can buy pollution rights and not use them Revenue can be used to fund pollution control Increasing costs give incentive for firms to invest in emissions controls

10. Asymmetric Information A situation where one party to a market transaction has much more information about a product or service than the other Buyers and sellers do not have the same information about price, quality or other aspects of a good/service

11. Moral Hazard Problem The possibility that individuals or institutions will change their behavior as the result of a contract or agreement Ex- a bank whose deposits are insured against loss may make riskier loans and investments -guaranteed contracts for pro athletes -careless drivers due to insurance

12. Adverse Selection Problem A problem arising when information known to one party to a contract or agreement is not known to the other party, causing the unknowing party to suffer major losses EX- the sickest individuals buy the most medical insurance
