Suppose that a monopolistically competitive restaurant is currently serving 230 meals per day (the output where MR = MC). At that output level, ATC per meal is $10 and consumers are willing to pay $12 per meal. What is the size of this firm’s profit or loss? Will there be entry or exit? Will this restaurant’s demand curve shift left or right? In long-run equilibrium, suppose that this restaurant charges $11 per meal for 180 meals and that the marginal cost of the 180th meal is $8. What is the size of the firm’s profit? Suppose that the allocatively efficient output level in long-run equilibrium is 200 meals. Is the deadweight loss for this firm greater than or less than $60
Suppose that a typical firm in a monopolistically competitive industry faces a demand curve given by: q = 60 − (1/2)p, where q is quantity sold per week. The firm’s marginal cost curve is given by: MC = 60. 1. How much will the firm produce in the short run? 2. What price will it charge? 3. Draw the firm’s demand, marginal revenue, and marginal cost curves. Does this solution represent a long-run equilibrium? Why or why not?
Sometimes oligopolies in the same industry are very different in size. Suppose we have a duopoly where one firm (Firm A) is large and the other firm (Firm B) is small, as shown in the prisoner’s dilemma box in Table 5.Firm B colludes with Firm AFirm B cheats by selling more outputFirm A colludes with Firm BA gets $1,000, B gets $100A gets $800, B gets $200Firm A cheats by selling more outputA gets $1,050, B gets $50A gets $500, B gets $20Assuming that the payoffs are known to both firms, what is the likely outcome in this case?
In this assignment, we’re assuming you’re a manager of different types of buffalo wing restaurants. I’ll give different scenarios- some will require math and others will require writing.
Cournot Oligopoly
2. Now, assume your buffalo wing firm is in a Cournot oligopoly with 3 additional firms. The market elasticity of demand for buffalo wings is -0.70. Find your firm’s elasticity of demand.
Now find the profit-maximizing price for your firm if your marginal cost is $3.70.

- Question 25 Consider two cigarette companies, PM Inc. and Brown Inc. If neither company advertises, the two companies split the market and earn $60 million each. If they both advertise, they again split the market, but profits are lower by $20 million since each company must bear the cost of advertising. Yet, if one company advertises while the other does not, the one that advertises attracts customers from the other. In this case, the company that advertises earns $70 million while the company that does not advertise earns only $30 million. What will these two companies do if they behave as individual profit maximizers? Both companies will advertise. Brown Inc. earns $40. Neither company will advertise. Brown Inc. earns $60. Both companies will advertise. PM Inc. earns $60. One company will advertise, and the other will not. Brown Inc. earns $70.arrow_forwardExplain the difference in market power between perfectly competitive firms and monopolistically competitive firms.

Finally, why would a firm choose to operate at a loss in the short run? When would it decide to shut down production temporarily?arrow_forward
- Suppose we have a duopoly with Firm 1 and Firm 2 and the following inverse demand function:P = 100 – 5(Q1 + Q2)Total Cost and Marginal Cost values for firms 1 and 2 are:TC1 = 20Q1TC2 = 30Q2MC1 = 20MC2 = 30Assuming a Cournot Duopoly, the following response functions are derived:Firm 1: Q1 = 8 – 0.5Q2Firm 2: Q2 = 7 – 0.5Q1Using this information, calculate the quantity produced for each firm, the price, and profits foreach firm and the market as a whole.arrow_forwardConsider an industry with two firms, each of which has a constant marginal cost of 20.

- At a time when demand for ready-to-eat cereal was stagnant, a spokesperson for the cereal maker Kellogg’s was quoted as saying, “ . . . for the past several years, our individual company growth has come out of the other fellow’s hide.” Kellogg’s has been producing cereal since 1906 and continues to implement strategies that make it a leader in the cereal industry. Suppose that when Kellogg’s and its largest rival advertise, each company earns $2 billion in profits. When neither company advertises, each company earns profits of $16 billion.If one company advertises and the other does not, the company that advertises earns $56 billion and the company that does not advertise loses $4 billion.

Is it monopolistically competitive or an oligopoly? Are the main products/services more commoditized, highly differentiated, or blockbuster? How does the market structure affect the ability of the firm to control the prices it charges for its products and for the prices it pays for its inputs? The more a firm can control its prices, the more it can control the income statement and EPS.arrow_forwardAt a time when demand for ready-to-eat cereal was stagnant, a spokesperson for the cereal maker Kellogg’s was quoted as saying, “ . . . for the past several years, our individual company growth has come out of the other fellow’s hide.” Kellogg’s has been producing cereal since 1906 and continues to implement strategies that make it a leader in the cereal industry.
