I. In the following situations evaluate what happens to supply or demand for new homes in Bowling Green and how this affects the equilibrium price and quantity exchanged. First analyze which curve(s) are affected and in which direction it shifts. Then state what happens to the price and quantity of new homes.

Hint: you may find it helpful to graph the shifts in order to determine how price and quantity are affected.

Curve price quantity

(S or D) (,, no change) (,, no change)

due to lower gas prices

2. The population decreases

3. Apartment rents rise

II. In the following situations evaluate what happens to supply or demand for domestically produced new cars and how this affects the equilibrium price and quantity exchanged. First analyze which curve(s) are affected and in which direction it shifts. Then state what happens to the price and quantity of new cars. Hint: you may find it helpful to graph the shifts in order to determine how price and quantity are affected.
