Q.6. Larry, Curly, and Moe run the only saloon in town. Larry wants to sell as many drinks
as possible without losing money. Curly wants the saloon to bring in as much revenue as
possible. Moe wants to make the largest possible profits. Using a single diagram of the
saloon's demand curve and its cost curves, show the price and quantity combinations
favored by each of the three partners. Explain.
One of the observations that has been made about the pricing of products produced in an industry where production is highly concentrated is that the costs of production can change up or down and yet prices do not change much. The Sweezy model was developed to explain this observation. Present a Sweezy model, show a cost change, and show that the optimal choice for the firm is to leave the product price unchanged. Provide words to explain the basic reason why the price does not move up or down as costs change.
Suppose that you are a manager for a firm like EBC Brakes, which manufactures brakes for automobiles and motorcycles. Your company has two plants, one in the United States and the other in the United Kingdom. The following tables include estimated demand and marginal revenue for your brakes, along with the marginal costs at the two factories.
what quantity and price maximize your firms profit?
What is the profit – maximizing number of brakes produced in the U.S. plant? In the U.K. plant?
Quantity Demanded (brakes per hour)
Price
(dollars per brake)
Quantity Produced in the U.K. plant (brakes per hour)
Quantity Produced in the U.S. (brakes per hour)
Total Quantity Produced
Marginal Cost (dollars per brake)
Marginal Revenue (dollars per brake)

- Three firms are producing a good and are competing in prices: consumers buy from the firm that has the lowest price, and each firm on its own can satisfy the entire market. If more than one firm choose the same price the demand is divided equally among them. There are no other firms in the market. Two firms have the same constant marginal cost cL and the third one has a higher marginal cost cH : cL < cH . Explain what will be the equilibrium price in this market.arrow_forwardThe market for lattes in Regina, Canada is shown in the attached graph. a) If a coffeehouse charges $4 for a latte, what is its per unit profit on each latte sold? Calculate the profit margin and label it on the graph. b) Assuming free entry and exit, so you expect more coffeehouses to enter this market? Why?arrow_forwardSuppose there are two types of cable TV viewers. The first type places a high value on sports channels (e.g., ESPN, Fox Sports, and the Golf Channel) and a low value on all other channels. The second type places a high value on music channels (e.g., VH1, MTV3, and CMT) and a low value on all other channels. In this case, we would expect cable operators to: use fixed-cost pricing. use "à la carte" pricing. sell sports and music channels in one bundle to both types of viewers. sell only sports channels to the first type of viewers and sell only music channels to the second type of viewers.arrow_forward

Her firm asks you how much to charge for her product to maximize profits. The demand schedule for it is given by the first two columns in the table below; its total costs are given in the third column. For each level of output, you can calculate total revenue, marginal revenue, average cost, and marginal cost. The profit-maximizing level of output can be found at the point where TR - TC is greatest, or where MR = MC, (or the last quantity where MR is still greater than MC.)

- Lucia owns a plot of land in the desert that isn't worth much. One day, a giant meteorite falls on her property, making a large crater. The event attracts scientists and tourists, and Lucia decides to sell nontransferable admission tickets to the meteor crater to both types of visitors: scientists (Market A) and tourists (Market B). The following graphs show daily demand (D) curves and marginal revenue (MR) curves for the two markets. Lucia’s marginal cost of providing admission tickets is zero. Suppose that at first, Lucia charges the same price of $4 per admission in both markets so that the total number of admissions demanded is______tickets. Suppose now that Lucia decides to charge a different price in each market. To maximize revenue, Lucia should charge_________per admission in Market A and________per admission in Market B. At these prices, she will sell a total quantity of _________admission tickets per day.
