Suppose a certain city has a monopoly cable-television company. This company has total costs TC = Q2 + 10Q + 75. (Hint: using calculus, this means MC = 2Q + 10 since MC is the derivative of TC with respect to output.) The demand in the community is approximated by the equation Qd = 85 - P/2 (alternatively, you can write the demand equation as Qd = 85 – 0.5P). Graphically depict the demand curve as well as the marginal cost (MC) curve. If the cable company is free to choose its own price Pm and quantity Qm, graphically depict the monopoly equilibrium price and quantity. Add any other curve(s) to your diagram that may be required to obtain this outcome. Compute and state the exact monopolist equilibrium price Pm and quantity Qm that you depicted graphically.
A monopolist sells in 2 markets and produces in 1 factory. Although the monopolist can charge difference prices in the two markets, it must sell all units within a market at the same price. a) Suppose this monopolist does not have a marginal cost (MC = 0). If demand in market 1 isX1(p1) = a1 - b1p1 and demand in market 2 is X2(p2) = a2 - b2p2, set up the monopolist's profit maximization problems and solve for the market prices that result in each market. b) Under what conditions on a1, b1, a2, b2 from above will the monopolist not price discriminate? c) If demand in market i, where i = 1 , 2, is instead Xi(pi) = ai pi^(-bi) and the monopolist has some constant marginal cost of c, where c > 0, set up the monopolist's profit maximization problem and solve for the market prices.
For a monopolist, it is typically a great idea to implement third-degree price discrimination (the one where the monopolist chooses different prices for different groups of customers) when the consumers can easily re-sell the good to one another after acquiring it from the monopolist. (a) True. (b) False.

A monopolist facing a demand p=1000 - 10Q has costs TC(Q) = 5Q^2 + 100Q. (a) What is the monopolist’s profit maximizing quantity and price? What is the induced DWL? (b) Suppose, on top of the costs above, the firm now also pays; (i) A flat fee of 1000 dollars, (ii) half of the profits, (iii) 150 dollars per unit sold, (iv) half of the revenue. Separately for each of these 4 cases, calculate the profit maximizing price and quantity for the monopolist with these new augmented costs. Does any of these scenarios alter the DWL associated with the monopoly, compared to (a)? (c) Forget about (a) and (b), and consider a monopoly in general. Show on a single graph with general costs (ATC and MC graphs) and a general demand, what quantity monopoly should produce in order to maximize ; (i) Total Revenue, or (ii) the number of units sold, under the condition that the firm does not make losses
A chemical manufacturer uses chemicals 1 and 2 to produce two drugs. Drug 1 must be at least 80% chemical 2 and drug 2 must be at least 75% chemical 1. Up to 70,000 ounces of drug 1 can be sold at $40 per ounce; up to 50,000 ounces of drug 2 can be sold at $15 per ounce. Up to 65,000 ounces of chemical 1 and up to 42,000 ounces of chemical 2 can be purchased. Formulate this problem as a linear programming model (using algebraic notation) to determine how to maximize the manufacturer's revenue. (You only need to formulate this problem as an algebraic model. No Excel spreadsheet model. No need to solve the model.)
true or false The oligopolist reduces the price of the good by 10%, but the competitors reduced their prices by 8%. As a result, the oligopolist only attracts only an additional 5% consumers from his competitors, This will reduce the total revenue of the oligopolist.

Four companies (Firm 1, 2, 3 and 4) are producing a product for the market. Each company will decide the number of products produced. You are given that • . Each firm can choose its qi. Given the quantites produced by four companies (denoted by 91, 92, 93, 94 respectively), the market price of the product is P = 400 - 91-92-93 - 94. Cost of producing one product is 20 (*Note: So the total cost for producing qi units of product is 20qi. Firm 1 and Firm 2 will first decide the quantities produced simultaneously at the beginning. After knowing 91 and 92, Firm 3 and Firm 4 will decide the quantities produced simultaneously. (a) State the strategic profiles of each firm. (b) Find all possible subgame perfect equilibrium for this games. Provide full justification to your answer.
Edinburgh Tyre Company (ETC) sells identical tyres under the firm's own brand name and private label tyres to discount stores. The tyres sold in both sub-markets are identical, and the marginal cost is constant at £10 per tyre for both types. The firm has estimated the following demand curves for each of the markets. PB 70 0.0005QB (brand name) and PP 20-0.0002QP (private label). Quantities are measured in thousands per month and price refers to the wholesale price in pounds. ETC currently sells brand name tyres at a wholesale price of £28.50 and private label tyres at a wholesale price of £14. Which of the following statements is true? Select one: O a. O b. ○ c. The brand name price is too low and the private label price too high relative to the profit maximising prices. Both prices are too high relative to the profit maximising prices. Both prices are too low relative to the profit maximising prices. Od. The brand name price is too high and the private label price too low relative to…
(Screening Problem) A monopolist decides both the price p and the quality q of the product he sells. Each buyer buys exactly one unit, but buyers vary in terms of their preferences for quality. There are two types of buyers: high-type with utility functions UH (q, t) = 2/q-p and low-type with utility function U (q, t) = vq – p. Let the probability of drawing a high-type buyer is 0.2. The cost of production for quality level q is just q (i.e., c(q) = q). The monopolist attempts to maximize his revenue by offering a menu of contracts {(qL, PL), (qH, PH)}. Find the optimal screening contract for the monopolist. %3D
