The market demand function for corn is Qd = 15 - 2P and the market supply function is Qs = 5P -2.5, both measured in billions of bushels per year. The initial equilibrium price is $2.50, and the initial equilibrium quantity is 10 billion bushels. Consumer surplus is $25, producer surplus is $10 and aggregate surplus is $35. Suppose the government wants to raise the price of corn to $3. What are the welfare effects of a price floor, price support, production quota, and voluntary production reduction program?
