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) Suppose ConcreteMex is a price taker in the competitive market in Texas. If the market price in Texas is Pc= 0.4, what is ConcreteMex’s supply Qs and profit in Texas? What is its supply if the price is Pc = 3? b) In a diagram, illustrate how the marginal cost and average total cost in Texas vary as a function of Q, and how ConcreteMex’s supply in Texas varies with price Pc. c) If the price in Texas is ?! = 3, what is ConcreteMex’s profit at its optimal supply in part a? Is the profit positive (or equal to zero)? Explain why the firm can earn positive (zero) profit in the competitive market.

Suppose a monopolist faces a market demand that is the first two columns in the table below. Also, in the short run, assume that Total Fixed Cost equals $100 and the monopolist has Total Variable Cost according to the table. Find Total Revenue for each price and quantity combination, and then Marginal Revenue as price falls and quantity increases. Fill in the rest of the costs in the table and find profit at each price and quantity combination as the difference between Total Revenue and Total Cost. If profit is less than zero that indicates a loss. What is the maximum profit you found in this table? At what quantity and price combination is profit maximized for this monopolist? Next, verify this result by using Marginal Analysis to find the profit maximizing price and quantity combination. For each quantity, ask yourself if Marginal Revenue exceeds Marginal Cost. If it does, then profits would be increased by producing that quantity. As you go down the table to higher quantities, stop…

= 240 + 0.5Q², and face 4. A monopolist has the cost function TC(Q) market demand P = 45 – Q. (a) Find the monopoly equilibrium price and output. Find the monopolist's profit.

Eyeglasslux is a single-price monopolist in the eye-glass frame market. It faces a Market demand given by Q=378-2P. Its Total Cost function is TC=6,422+20Q and Marginal Cost is MC=20. If the government imposes a price ceiling of $27, what is the monopolist's QUANTITY in the SHORT- run?

There are two types of consumers: one half of consumers are type 1 (low type) and the other half are type 2 (high type). Type l's demand curve is q1 = 8 – P, while type 2's demand is given by q2 = 12 – P. Consider a monopolist selling its product to these consumers. Assume that the marginal cost is equal to zero. 1.1. Suppose that the firm can charge only one price, P, for each unit. (1) What is the market demand, Q? (Note: Q should be equal to q1 + q2.) What should be P that maximizes the monopoly's profit? For the profit- (2) maximizing P, will both types of consumers purchase the product, or only high type con- sumers purchase? (3) Given the price in (2), what is the resulting social surplus?

A movie monopolist sells to college students and other adults. The demand function for students is Q = 840 - 100P, and the demand function for other adults is Q = 1,600 - 100P. Costs is c(Q) = 12 +0.005Q2m per ticket, where Q=Qs+ QA- Instructions: Round your answers to 2 decimal places. a. What prices will the monopolist set when she can discriminate? Pstudent = $ per ticket. Padult = $ Profit = $ per ticket. b. What if demand for adults increases to Q = 1,800 - 100P? Pstudent = $ Padult = $ Profit = $ per ticket. per ticket. c. When adult demand increases, the adult price: decreases. does not change. increases. d. When adult demand increases, the student price: decreases. increases. does not change.

The monopolist is productively-efficient, because, like the perfect competitor, it operates at minimum ATC is the long-run. True False

Assume that a monopolist faces a demand curve for its product given by: p=130−3q Further assume that the firm's cost function is: TC=490+10q What is the profit for the firm at the optimal quantity and price?

Suppose Bang Bang is the only local swimming pool. She believes that there are 10 potential customers. Each of them has an identical demand function of QI = 250 – 0.02P, with QI as the unit of services of each customer. She operates with a constant variable cost of $500 per unit of service.   If Bang Bang is a single price monopoly, calculate the price she should charge for her service. Show your calculations.
