Suppose that the demand function and supply function for corn are:
Qd = 100 − 4Pcorn
Qs = 2Pcorn − 17
(a) What is the equilibrium price of corn? What is the amount of corn bought and sold?
(b) What is the total consumer surplus, producer surplus and aggregate surplus at the equilibrium price/output?
(c) Graph the supply & demand and illustrate the consumer & producer surplus.
(d) Suppose that the government put a limit on total corn production to 20. What is the deadweight loss from producing at 20 vs. the equilibrium quantity?
