ECONOMICS
(SECONDARY)
ESSENTIAL UNIT 3 (E03)
(Supply & Demand, Price Controls)
(July 2015)
Unit Statement: The student will learn about the supply and demand model. He/she will
examine the supply and demand curves and how their interaction determines equilibrium
market price and quantity. The student will also learn about the difference between a
movement along a curve and shifts of the curve. He/she will examine the causes of shortages
and surpluses using this model. The interaction between supply and demand underlies nearly
all important economic concepts.
Essential Outcomes: (must be assessed for master)
1. The Student Will define and explain a competitive market.
2. TSW derive a demand curve from a demand schedule.
3. TSW explain the downward slope of the demand curve using the interaction of price
and quantity.
4. TSW derive a supply curve from a supply schedule.
5. TSW explain the upward slope of the supply curve using the interaction of price and
quantity.
6. TSW distinguish between a change in demand/supply and a change in quantity
demanded/supplied.
7. TSW apply the supply and demand model to explain the five main shifters of the
demand curve.
8. TSW apply the supply and demand model to explain the five main shifters of the
supply curve.
9. TSW identify and explain the concept of equilibrium price and quantity.
10. TSW explain causes of shortages and surpluses using the supply and demand model.
11. TSW identify and explain producer and consumer surplus.
12. TSW analyze problems caused by price and quantity controls.
13. TSW diagram inelastic, elastic, and unit elastic supply and demand curves.
14. TSW define and apply Key Terms and Concepts (pg. 21).
