- Assume perfect competition takes place in the market for hotel rooms. The the current market equilibrium price of a standard room is RM300 per night. a. Show that the current market balance is efficient, assuming that both the marginal cost borne by the seller and the marginal profit which the buyer feels reflects all the costs and benefits associated with production and use of hotel rooms.

Dirk wants the bar to bring in as much revenue as possible. Franz wants to make the largest possible profits. Using a single diagram of the bar's demand curve and its cost curves, show the price and quantity combinations favoured by each of the three partners. Explain.arrow_forwardHenry Potter owns the only well in town that produces clean drinking water. He faces the following demand, marginal revenue, and marginal cost curves:Demand: P = 70 – QMarginal revenue: MR = 70 – 2QMarginal cost: MC = 10 + Qa) Graph these three curves. Assuming that Mr. Potter maximizes profit, what quantity does he produce? What price does he charge? Show these results on your graph.b) Mayor George Bailey, concerned about water consumers, is considering a price ceiling that is 10 percent below the monopoly price derived in part (a). What quantity would be demanded at this new price? Would the profit-maximizing Mr. Potter produce that amount? Explain. (Hint: Think about marginal cost.)c) George’s Uncle Billy says that a price ceiling is a bad idea because price ceilings cause shortages. Is he right in thiscase?

Which number corresponds to consumer surplus on the graph? C. Which number corresponds to producer surplus on the graph? Which number corresponds to deadweight loss on the graph?arrow_forwarda. suppose that the supermarkets combine to form one chain. Using a new diagram, show the equilibrium price and quantity. What is the deadweight loss in this case? Indicate the consumer and producer surplus, how have they changed? b.Assume that the newly formed supermarkets chain can perfectly price discriminate (hint: it means they can charge each consumer the maximum price they he/she is willing to pay – think about our experiment in the lecture deriving the demand curve for your favourite singer’s tickets). How much will be sold and what will be the deadweight loss in this case? Discuss how policymakers approach these sorts of situations, and why.arrow_forwardYou live in a town with 300 Adults and 200 children, and you arc thinking about putting on a play to entertain your neighbors and make some money. A play has a fixed cost of $2,000, but selling an extra ticket has zero marginal cost. Here are the demand schedules for your two types of customer: a. To maximize profit, what price would you charge for an adult ticket? For a child's ticket?How much profit do you make?b. The city council passes a law prohibiting you from charging different prices to different customers. What price do you set for a ticket now? How much profit do you make?c. Who is worse off because of the law prohibiting price discrimination? Who is better off? (If you can, quantify the changes in welfare.)d. If the fixed cost of the play were $2,500 rather than $2,000, how would your answers to parts (a), (b), and (c) change?arrow_forward
