Answer:
A) Equilibrium quantity will increase; the effect on price is ambiguous.
Step-by-step explanation:
the demand and supply curves of apple pies will shift due to these events:
- a decrease in the price of apples will shift the supply curve to the right, increasing the total quantity supplied at every price level ⇒ QUANTITY↑ while PRICE↓
- consumer expectations will shift the demand curve to the right, increasing the total quantity demanded at every price level ⇒ QUANTITY↑ and PRICE↑
Both events will cause the equilibrium quantity to increase, but one event will decrease the price, while the other will increase it. For sure we know that the equilibrium quantity will increase, but the effect on the equilibrium price is unknown.
