Suppose that the demand and supply relations are given by the following equations

QD=12,000-2,000P (Market Demand)

QS=1,000P (Market Supply)

where Q is quantity of products, and P is the price per unit.

(A). Calculate the perfectly competitive industry equilibrium price/output combination.

(B). Now assume that the industry output is organised into a cartel. Calculate the industry price/output combination that will maximise profits for cartel members. Note that if demand equation P=a-bQ, then marginal revenue MR=a-2bQ. (10 points)

(C). Compare your answers to parts (1) and (2). Calculate the price/output effects of the cartel.

(D). Calculate the social welfare loss after the the industry output is organised into a cartel.
