Answer to Question 1

There are two possible causes of the drop in price: a decrease in demand or an increase in supply. If demand decreases, equilibrium quantity also falls. Thus, this could not be the cause of the changes in the peanut market. On the other hand, an increase in supply lowers equilibrium price while increasing the equilibrium quantity sold. Therefore, the supply of peanuts must have increased.

Answer to Question 2

a) The quantity is the efficient quantity, Q3.
b) The price is P2.
c) When the firm is regulated using a marginal cost pricing rule, the consumer surplus is equal to the area of the triangle P1dP2.
d) The loss per unit is the amount equal to the distance cd.
