A monopolist sells the same product at the same price into two different markets. The demand
for the product in market #1 is denoted D,(p) = 15 – p where p is the unit price. The demand
for the product in market #2 is given by D2(p) = 40 – 6p.
1. If the monopolist sets a price of $8 per unit, what is the total demand?
2. Explain why elasticity of total demand is not defined at a unit price of 20.
3
A monopolist serves a market with five potential buyers, each of whom would buy at most one piece of the monopolist’s good. Anna would be willing to pay up to £80 for it, Bob up to £90, Chloe up to £100, Dave up to £110 and Elizabeth up to £120. The monopolist’s variable cost function is given in below table.
a) Indicate in the table which price the monopolist would want to charge for each given quantity. b) Find the marginal revenue for each quantity. c) Find the monopolist’s profit maximising price under the assumption that he wants to produce anything at all. d) How large can the monopolist’s fixed costs be such that he still wants to start producing at all?

- A monopolist is selling a product with a linear demand curve with a vertical intercept of P=10 dollars (a price above which no one will buy the product) and a horizontal intercept of 20 thousand (the amount people would consume of the product were free). The product has zero marginal cost of zero (e.g., downloadable software). The profit-maximizing monopolist will set a price equal to dollars, produce and sell a quantity of thousand units, and will earn revenue of thousand dollars.arrow_forwardQuestion 4 Consider a monopolist facing two consumers with the following two inverse demand functions: P=200-4Q₁ and P=122- 6Q2. Assume that fixed costs are zero and that the marginal cost is equal to $8. a) Suppose the monopolist can differentiate between the two consumers. The monopolist decides to use a two- part tariff that permits both consumers to stay in the market. Solve for each consumer's demand, fixed fee and monopolist profits. b) Assume the monopolist cannot differentiate between the two consumers and hence cannot apply a two-part tariff. decides to serve both consumers. Solve for the equilibrium aggregate demand and price in market, demand of each consumer and the monopolist profit. c) Now assume the monopolist decides not to serve the low demand consumer. Solve for price, demand and monopolist profits. Is the monopolist better off as a result of eliminating the low-volume consumer from the market?arrow_forwardA monopolist produces an output level Q1 = 200 where marginal revenue is equal to marginal cost. At this output level, the price is P1 = $300 and the average total cost is ATC1 = $250. The monopolist has the following revenue and cost levels:• Marginal cost curve intersects the marginal revenue curve at $100.• Marginal revenue is $0 at Q2 = 400.• Marginal cost curve intersects the demand curve at P3 = $270 and Q3 = 320.1. Draw the graph for the monopolist (include ATC, D, MC, and MR curves). Label everything! 2. At this output of Q1 = 200, calculate total revenue (TR), total cost (TC), and profit. Show your work (formulas and calculations). 3. Let’s compare the monopoly outcome with the perfectly competitive outcome. In monopoly, the firm produces Q = ________ and charges a price P = $_______. If this was perfect competition, the market would produce Q = ________ and charge a price P = $_______. Which market is more efficient and why? (hint: economic welfare) Obs:…arrow_forward
- The following graph shows the marginal cost (MC), marginal revenue (MR), average total cost (ATC), and demand (D) for a monopolist. Suppose that this monopolist cannot price discriminate. Place the grey point (star symbol) on the graph to indicate the profit-maximizing price and quantity for this monopolist. If the monopolist is making a profit, use the green rectangle (triangle symbols) to shade in the area representing its profit. On the other hand, if the monopolist is suffering a loss, use the purple rectangle (diamond symbols) to shade in the area representing its loss.

Find the profit maximising output for this firm. What is the price that the competitive firm must charge? The government decides to impose a new policy on this monopolist. In particular, the government wants to introduce price regulation such that the regulated price will consequently make this monopolist earns zero profit only.

How many quantities of output are produced with this new regulated price?arrow_forwardConsider a monopolist operating on a market with a downward sloping demand curve. The monopolist has a constant marginal cost and no fixed cost. At the current level of production and at the current price level, the price elasticity of demand is equal to -0.8.
