Question 4Think a price making firm (monopolist) with a downward-sloping demand curve is one with a price elasticityof demand equal to-1. This is illustrated in the following diagram.P=AR20Expenditure stays thesame as price changesTRAR = =Qd (TR)dQSlope = b/Q40100Diagram 5 Unit elastic demand (Pe=-1)MR =As price and quantity change by the same proportion, total revenue is the same at each price (the TR curve ishorizontal). This gives the following TR, AR and MR equations:TR=bb-D (AR)Q= 0QAs TR is constant at all outputs, so MR must equal zero. In diagram 5, what is the value of b in equationTR=b?

Q14 Monopolists, like firms in other market structure, strive to maximize profit. Microsoft when it first came out with its Windows operating system was thought to be a monopolist. Assume that Microsoft is a monopolist and calculates that at its present output level, marginal cost is $5.50 and marginal revenue is $4.50. Microsoft could increase profits by Multiple Choice decreasing output and leaving price unchanged. increasing price and decreasing output. decreasing price and increasing output. leaving both quatity and price unchanged. decreasing price and leaving output unchanged.
If the monopolist shown in the following figure could implement a two- part tariff, the entry fee would be: $0. $225. $450. $900. $1,200.
1. A firm faces the following inverse demand curve: P = 500 - 0.25Q Where: Q is the monthly production P is price, measured in dollars per unit. The firm also has a total cost (TC) function of: TC = 200Q. Assuming the firm maximizes profits, answer the following: a) Assuming the firm operates as a monopolist, calculate the following: price, quantity, and profit. Graph and show the equilibrium price and quantity. b) Assuming perfect competition, what are price, quantity and profit? Show on the graph from above.
There is a monopolist,ConcreteMex,in the concretemarketin Mexico. The demand function is QD= 100–50p. The marginal cost of production isc=0.4. (referencing) Question 1.3 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 ConcreteMex 0.2dollars. What are the new profit-maximizing price and production levels for ConcreteMex? Under the subsidy policy and the new price in Question 1.3, calculate the consumer surplus, producer surplus, and deadweight loss. You do not need to consider government spending for the deadweight loss.

Alex Potter owns the only well in a town that produces clean drinking water. He faces the following demand P=100-Q, and marginal cost MC=20+2Q, marginal revenue MR= 100-2Q curves. In order to maximize profits, Alex should charge a price of $60 at the profit maximizing quantity with a marginal revenue equal to $60. $60 at the profit maximizing quantity with a marginal revenue equal to $80. $80 at the profit maximizing quantity with a marginal revenue equal to $80. $80 at the profit maximizing quantity with a marginal revenue equal to $60.
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. Quantity Variable Costs 1 3. 4. 40 90 150 220 300 Price Marg. Revenue 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 1.

Question 33 Suppose a monopolist faces the demand curve P = 200 – 2Q, has marginal cost curve MC = 2Q, and zero fixed costs. If the monopolist can perfectly price discriminate, which of the following is true? The monopolist sells 33 units at a profit of 3300. The monopolist sells 33 units at a profit of 1650. The monopolist sells 50 units at a profit of 5000. The monopolist sells 50 units at a profit of 2500.
