2. Section One – Prices as Signals
Advantages of Prices
i. Prices favor neither the producer or consumer
ii. Prices are flexible
iii. Can accommodate change
iv. No cost of administration
II. Allocations Without Prices
i. Rationing (w/coupons) – The government decides everyone’s “fair-share”

The Price Adjustment Process
a. An Economic Model

5. b. Market Equilibrium
i. Quantity of goods and services supplied is equal to the quantity demanded
c. Surplus
i. A situation where the quantity supplied is greater than quantity demanded
- forces the prices down
d. Shortage
i. A situation where the quantity demanded is greater than quantity supplied
- forces prices up
e. Equilibrium Price
i. The price at which there is neither a shortage or surplus

6. II. Explaining and Predicting Prices
a. Changes in Supply
i. Increases or decreases in supply can change prices
b. Importance of Elasticity
i. Price changes tend to be wider if both products are inelastic
ii. Prices will be less volatile if both curves are elastic
c. Changes in Demand
i. Changes in demand also effect prices
III. The Competitive Price Theory
i. Allocate resources efficiently

7. Section Three – Social Goals vs. Market Efficiency
Distorting Market Outcomes
i. Setting prices as “socially desirable levels”
ii. Prices are not allowed to reach their equilibrium
a. Price Ceilings – A maximum legal price that can be charged for a product
i. These ceilings have the opposite intended effect (shortages, minimum upkeep, allocated resources somewhere else, waiting lists)

8. b. Price Floors – The lowest legal price that can be paid for a good or service
i. Minimum wage is a price floor
ii. Does it lead to unemployment?
iii. Is it efficient?
iv. Why would we implement it?

9. II. Agricultural Price Supports
a. Loan Supports
i. Loans given to support production at a higher price
b. Deficiency Payments
i. Checks sent to producers that make up the difference between actual market price and the target price (limited production)
