Question 5 A monopolist sells in two markets. The demand curve for her product is given by p₁ = 119 - 2x₁ in the first market and P₂ = 123 - 5x₂ in the second market, where x; is the quantity sold in Market i and p₁ is the price charged in Market i. She has a constant marginal cost of production, MC = 3; and no fixed costs. She can charge different prices in the two markets. What is the profit-maximizing combination of quantities for this monopolist?

I need an answer for Part D A monopolist is selling in a market with two types of consumers, type H and type L. There are 30 type H consumers, each with demand function qH= 10 –0.02P, and 50 type L consumers, each with demand function qL= 7–0.04P. Marginal cost is constant and equal to 40, and fixed cost is equal to 5000. a. Suppose that the monopolist can prevent the existence of a second-hand market. In other words, there can be no resale of the product between consumers after the initial purchase from the monopolist. What would the profit be for the monopolist from charging only one price to the entire market? b. Again, with no second-hand market possible, suppose the monopolist can distinguish between type H and type L consumers and can offer a discount to type L consumers. What are the profit-maximizing prices the monopolist will charge? How many units of goodwill each type of consumer buy? What will the monopolist’s total profit be? c. What is total consumer surplus with only one…

There is a monopolist, Concrete Mex, in the concrete market in Mexico. The demand function is Qd= 100-50p. The marginal cost of production is c = 0.4. a) Calculate the consumer surplus, producer surplus, deadweight loss, and illustrate them in a graph. b) ConcreteMex claimed the high price is due to high transportation costs and persuaded the government to help cut down the costs. As a result, for every unit of concrete sold, the government subsidizes Concrete Mex 0.2 dollars. Under the subsidy policy and the new price, calculate the consumer surplus, ptooducer surplus, and deadweight loss. You do not need to consider government spending for thee deadweightoss. c) What is the total government expenditure for the subsidy policy? Compare your answers in questions a  and b.  , and argue who benefit more from the policy, the consumers or ConcreteMex? Illustrate and explain how the producer surplus changes from Question 1.2 to 1.4 in a diagram.

7. A monopolist faces inverse demand p(Q) = 22 - 2Q and has total cost function TC(Q) = 2Q. a. Calculate the equilibrium price, quantity, consumer surplus, and producer surplus if the monopolist must charge all consumers the same price. b. Suppose instead that the monopolist can perfectly price discriminate among consumers. What are the price, quantity, consumer surplus, and producer surplus now? c. Alternatively, the monopolist decides to charge a two-part tariff. What lump sum fee and price per unit should the monopolist charge if consumers are homogeneous?
