Corpus Industries produces a product at constant marginal cost that it sells in a monopolistically competitive market. In an attempt to bolster profits, the manager hired an economist to estimate the demand for its product. She found that the demand for the firm’s product is log-linear, with an own price elasticity of demand of –10 and an advertising elasticity of demand of 0.2. To maximize profits, what fraction of revenues should the firm spend on advertising?

As a manager of a chain of movie theaters that are monopolies in their respective markets, you have noticed much higher demand on weekends than during the week. You therefore conducted a study that has revealed two different demand curves at your movie theaters. On weekends, the inverse demand function is P = 20 - 0.001Q; on weekdays, it is P = 15 - 0.002Q. You acquire legal rights from movie producers to show their films at a cost of $25,000 per movie, plus a $2.50 "royalty" for each moviegoer entering your theaters (the average moviegoer in your market watches a movie only once). What price should you charge on weekends? What price should you charge on weekdays?
As a manager of a chain of movie theaters that are monopolies in their respective markets, you have noticed much higher demand on weekends than during the week. You therefore conducted a study that has revealed two different demand curves at your movie theaters. On weekends, the inverse demand function is P = 20 − 0.001Q; on weekdays, it is P = 15 − 0.002Q. You acquire legal rights from movie producers to show their films at a cost of $25,000 per movie, plus a $2.50 “royalty” for each moviegoer entering your theaters (the average moviegoer in your market watches a movie only once). Devise a pricing strategy to maximize your firm’s profits.

You are a monopolist.$ b. You compete against one other firm in a Cournot oligopoly.$ c. You compete against 19 other firms in a Cournot oligopoly.$
Suppose a monopolistically competitive firm is in long-run equilibrium. The firm's demand curve is tangent to its average cost curve at Q = 25. Average cost is minimized at Q = 35, where average cost is $50. Which of the following is true? Group of answer choices This firm maximizes profit at an output level of 35 units. This firm maximizes profit at an output level lower than 25 units. This firm maximizes profit at an output level of 25 units. This firm incurs an economic loss in the long run. This firm maximizes profit at an output level greater than 35 units.

A manager of a nightclub realizes that demand for drinks is more elastic among students and is trying to determine the optimal pricing schedule. Specifically, he estimates the following average demand for his customer types: Under 25: qr =18-5p Over 25: q=10-2p The two age groups visit the nightclub in equal numbers on average. Assume that drinks cost the club $2 to make. If the manager can charge a separate entry fee and a price per drink for each group, what two-part price will the manager set for reach group. Now suppose that once again it is impossible to identify which group the customers belong. Suppose the manager lowers the price of drinks to equal to marginal cost and still wanted to attract both customers, what entry fee would the manager set? Compare the profits earned in parts a) to d). Which scheme would you choose if you could not identify customer type and which would you choose if you could identify customer type.
There are two competing Internet-based providers of medical information suitable for patients. ProPatient currently charges $150 per year to subscribers of its service which helps patients learn more about their medical conditions. Its competitor, AskUs Health, currently charges $125 for a similar service. The current level of advertising by ProPatient is $2,500,000. ProPatient has tracked its volume of subscribers as a function of its price, the price of AskUs services, and of its own marketing expenditures designed to promote the service. The marketing department at ProPatient estimated its demand relationship based on these data. Here is the result:QP = 120,000 - 900PP + 400PA +.02MPwhere QP = quantity of subscribers to ProPatient PP = price charged by ProPatient PA = price charged by AskUs Health M P = Marketing expenditures by ProPatient(all values of the independent variables are in dollars)ProPatient’s fixed cost to establish and maintain the business is $10,000,000 plus…

The manager of a convenience store competes in a monopolistically competitive market and buys cola from a supplier at a price of $1.25 per liter. The manager thinks that because there are several supermarkets nearby, the demand for cola sold at her store is slightly more elastic than the elasticity for the representative food store reported in Table (which is −3.8). Based on this information, she perceives that the elasticity of demand for cola sold by her store is −4. What price should the manager charge for a liter of cola to maximize profits?
A monopolistic producer of two goods, 1 and 2, has a joint total cost function TC=10Q_(1)+Q_(1)Q_(2)+10Q_(2) where and denote the quantity of items of goods 1 and 2, respectively that are produced. If P1 and P2 denote the corresponding prices then the demand equations are P_(1)=50-Q_(1)+Q_(2) P_(2)=30+2Q_(1)-Q_(2) Using the Lagrange multiplier approach, find the maximum profit if the firm is contracted to produce a total of 15 goods of either type. Estimate the new optimal profit if the production quota rises by 1 unit.
GM’s Food Shops has completed a study of weekly demand for its “new-fashioned” tacos in 53 regional markets. The study revealed that where Q is the number of tacos sold per store per week, A is the level of local advertising expenditure, Pop denotes the local population (in thousands), and Pr is the average taco price of local competitors. For the typical GM’s outlet, P = P1.50, A = P1,000, Pop = 40, and Pr = P1. Q = 400 - 1,200P + 0.8A + 55Pop + 800Pr Estimate the weekly sales for the typical GM’s outlet. Determine the equilibrium price and equilibrium quantity, if supply is Qs = 700 + 1,200P considering the general demand function of GM’s outlet Should GM raise its taco prices? Why or why not?
