Verizon can be viewed as a first mover.  Now suppose both ATT and Verizon are considering whether and how to enter a potential market. Market demand is given by the inverse demand function p= 900−q1−q2, where p is the market price margin, q1 is the quantity sold by Verizon and q2 is the quantity sold by ATT. To enter the market, a retailer must build a store. Two types of stores can be built: Small and Large. The Small store requires an investment of $50,000, and it allows the retailer to sell as many as 100 units of the goods at zero marginal cost. Alternatively, they can pay $175,000 to construct a Large store that will allow it to sell any number of units at zero marginal cost. Assume Verizon enters and builds a Large store (i.e. chooses to build a Large store L1 at the first stage.) Calculate Verizon's profit for the following cases:   a.) ATT chooses not to enter N at the second stage after viewing Verizon's choice. b.) ATT chooses to build a Small store S at the second stage…

  • NutraSweet Aspartame is a low-calorie, high-intensity sweetener known by Monsanto’s brand name, NutraSweet. It was the key to the success of Diet Coke and Diet Pepsi in the 1980s. NutraSweet made billions of dollars, yielding very high profits. Such profits usually attract entry, but in this case entry was barred by a patent on the sweetener and because the process of creating the sweetener was expensive and difficult. Monsanto had a distinct capability—its monopoly. It had also created another strategic asset—the NutraSweet brand name as represented by its trademark ‘swirl.’ The problem was that Monsanto’s patent was about to expire. As a result, the Holland Sweetener Company began building an aspartame plant in Geleen, the Netherlands, to challenge Monsanto’s hold on the aspartame market. Holland Sweetener was a joint venture between the Japanese Tosoh Corporation and DSM (Dutch State Mines). What did Monsanto do?  Why? What did Holland Sweetener do?  Why?

  • Suppose that econometricians at Hallmark Cards determine that the price elasticity of demand for greeting cards is -2. (a) If Hallmark's marginal cost of producing cards is constant and equal to $1.00, use the Lerner Index to determine what price Hallmark should charge to maximize profit. (b) Suppose that Hallmark Cards wishes to know the price elasticity of demand faced by its archrival, American Greetings. Hallmark hires you to estimate it. Hallmark provides you with an educated guess concerning the marginal cost of producing a greeting card, which they estimate to be constant and equal to $1.22. A quick trip to the store tells you that American Greetings is selling its cards for an average of $3.25. Using these numbers and assuming that American Greetings is maximizing profit, calculate the price elasticity of demand faced by American Greetings   Note:- Do not provide handwritten solution.

  • 5. In a small college town there is only one movie theater. In a given month, if the theater is open, the owners have to pay a fixed amount of $6,000 for the films, ushers, etc., regardless of how many people come to the movies. For simplicity, assume that if the theater is closed, its costs are zero. The demand function for movie tickets in the town is characterized by ??= 45 −QT/60 a. Draw the market demand curve, the marginal revenue curve, and the marginal cost curve. Make sure to label the axes, curves, and intercepts. b. Find the profit-maximizing price and quantity of movie tickets, and indicate them on the graph above. How much would the theater make in profits?c. Suppose the local government implements a property tax, so that each month the theater now must pay a lump sum tax of $700. What will be the price and quantity of movie tickets under this tax?

  • Ecotripper Enterprises is the sole producer of Sunblast solar-powered skateboards, “The green alternative”. Market demand for Sunblasts is given by the formula: P=120-0.5Q, where p is in $ per skateboard and Q in skateboards per week. Total costs, in $ per week, are given by: TC=100+20Q, and marginal cost (MC) equal 20. a.) Derive the marginal revenue function and calculate the profit-maximizing price, quantity sold and the profit. b.) If the government imposes a price ceiling of $ 65 per skateboard, what is the effect on the equilibrium and the values derived in a.)? c.) If the government wanted Ecotripper to produce the socially efficient quantity of skateboards, what price ceiling could it set in the short run? What would the result be in the long run? d.) If the government decided to set the price ceiling so that consumer surplus was maximized subject to Ecotripper earning zero profits, what would be the level of the price ceiling, the quantity sold and the consumer surplus?
    Consider a duopoly with a leader (called L) and a follower (called F). The market demand is given as: P=500-0.25Q, where Q=QL+QF The total cost function for the leader is given as: TCL=0.03QL The total cost function for the follower is given as: TCF=0.1QF All variables are per day, per plant. What is the profit-maximizing quantity for the leader (per day, per plant)? (Note: Round your answer to two decimal points
    In terms of reputation for quality, imagine that we have a firm that can produce a good at any quality level in the interval [0, 1], where 0 means a good of low quality, and 1 means a good of exceptionally high quality. Demand for the good depends on consumer perceptions of the good's quality. If consumers anticipate that the good is of quality q, their demand is given by · P. = 4 + 6q - X, where X is the quantity demanded. Costs of manufacture depend on the quality level of the good being produced; it costs a constant marginal 2 + 6q2 to produce a unit of quality level q. Consider the repeated setting described in section 14.5: In each period, the firm chooses a quality level and price. Consumers see the price but not (until after they have bought) the quality level. But consumers do know the level of qualities the firm has produced previously. Assume the firm discounts profits with a discount factor a = .9. For which levels of quality q is there a viable reputational…
