Suppose a monopoly has constant marginal costs of $20 per unit. Demand for the monopolist’s product is Q = 100 - P. Please show the work to receive the full credit.

i. What are the profit maximizing price and quantity for this monopoly? (4)

ii. How many units of the product would the competitive market supply? What would the equilibrium price be? (4)

iii. Calculate how much consumer surplus would be lost if this market started off as perfectly competitive but then became monopolistic.

(4) iv. Calculate how much producer surplus would be gained if this market started off as perfectly competitive but then became monopolistic.

Consider a perfectly competitive market with demand Q=1,000-4P. The marginal cost for each firm in the market is constant at MC=4. Determine the competitive equilibrium price and quantity. . Graph demand, supply, and the equilibrium found in part A). Determine consumer surplus, producer surplus, and total surplus. Is consumer surplus or producer surplus equal to zero? Why or why not? Is this question representative of a long or short-run perfectly competitive market? How do you know?
