Which of the following explains the effect on equilibrium price and quantity in the corn market?
A. The quantity of corn will fall, but the effect on equilibrium price cannot be determined without more information. B. The price of corn will rise, but the effect on equilibrium quantity cannot be determined without more information. C. The quantity of corn will rise, but the effect on equilibrium price cannot be determined without more information. D. The price and quantity of corn will fall. E. The price and quantity of corn will rise. Answer: B. The price of corn will rise, but the effect on equilibrium quantity cannot be determined without more information.

A. shortage; rise; fall B. shortage; fall; rise C. surplus; fall; rise D. surplus; rise; fall Answer: A. shortage; rise; fall
At the market equilibrium price:
quantity demanded equals quantity supplied.
Given linear demand curves, if demand and supply both increase but demand increases by a greater amount than supply, then:
the equilibrium price and quantity both increase.
Given linear demand curves, if demand and supply increase by identical amounts, then:
the equilibrium price stays the same and the equilibrium quantity rises.
