4. Chelsea owns the only parking garage in town (i.e., she's a monopolist). Suppose that the marginal cost of letting an additional car in the garage is zero, and that the demand for parking in the garage is known.

(a) Show how Chelsea determines how many cars she will allow in the garage and how much she will charge each car to maximize her profits. Are profit maximization and revenue maximization equivalent in this case? Why or why not?

(b) Is it always profitable for Chelsea to fill the garage to capacity? Why or why not? Assume that Chelsea does not practice price discrimination.

Expert Solution

Q4 (a) The equilibrium condition that Chelsea uses to determine how many cars to allow is mearginal revenue from additional car = marginal cost from additional car

=> MR =0

yes profit maximization and revenue maximization are the same in this case

max Profit = max (Revenue - variable cost - Fixed cost)

= max(Revenue - Fixed cost) [since marginal cost = 0 => there is no variable cost]

= max Revnue - fixed cost [ as fixed cost is not depended on the number of cars and hence not affected at the equilibrium level]

Thus, max profits is the same as max revenue and both will gave the same number of cars

(b) No, it is not always profitable for Chelsea to fill the garage to capacity. This is because, if there is no price discrimination, the downward sloping demand curve means that the marginal revenue of allowing an extra car can become negative and lower than the marginal cost. In this case, the total profits will be lesser than maximum profits that can be achieved by followin MR=MC condition.

In the town of Kokomo, Marylin owns a well, which is the only source of drinking water. The supply of water is perfectly inelastic at a quantity of 1,000 gallons of water per day. At a price of $2.00 per gallon, the quantity demanded per day is 1,000 gallons. The government imposes a $0.50 per gallon tax. After the tax is imposed, what is the price paid by the villagers? What is the price received by Marylin? What is the...

Suppose that MUB is the only producer of electricity in the little town of Microeconomica. The faces a demand curve of the form: P = 210 – 4Q, where P (measured in dollars) and Q (measured in kilowatts) stand for the unit price and quantity of electricity produced, respectively. Suppose that in producing electricity for the town, MUB incurs production costs that total C(Q) = 5Q. a. What is MUB’s marginal cost function? b. How many kilowatts of electricity should...

Suppose that there is only one ﬁrm, the monopolist and many consumers in the market. Assume that the market demand function is given by P = 210−2Qd and the monopolist’s cost function is given by C(Q) = 10Q. (a) Setup the monopolist’s proﬁt maximization problem. (b) Solve the monopolist’s proﬁt maximization problem and ﬁnd the market equilibrium price P∗ and quantity Q∗. Now, assume that the government eliminates all the entry cost of entering the market as the government wants...

Suppose you and a rival are the only producers of oysters in a town. Each morning you harvest oysters to sell in the afternoon. You both have the choice to collect 10 or 20 dozen oysters. Each dozen has a marginal cost of $10 (so the cost of 10 dozen oysters is $100). If 20 dozen oysters in total are brought to the market, they will sell for $35 each. If 30 dozen oysters in total are brought to the...

Suppose that there are only three people that live in a (very) small town: Eric, Greg, and Katie. The town is thinking of building a park which you can assume is a public good for these three individuals in the town. Based on the individuals’ demand schedules for the park, which are given below, calculate and graph the social marginal benefit curve for the park. Eric’s Demand Greg’s Demand Katie’s Demand Price per Acre Number of Acres Price per Acre...

Suppose Rialto is the only movie cinema in a small college town, so it is essentially a monopoly for the local movie market. They charge a certain price P for a monthly pass. There is an overall demand curve for movie passes, given by P=900−4Q However, demand in the town has two distinct consumer groups: adults (A) and students (S). The demand for the whole group of adults is given by P=1200−8QA and the inverse demand for students is given...

4. Derek is the owner of the only movie theater in town. By hiring several well-trained economists, Derek learns that the people watching movies after 8 P.M. have a much higher average willingness to pay than people watching at 5 P.M. The costs of showing a movie are identical at 5 P.M. and 8 P.M. To maximize his profit, what should Derek do? Give him some specific advice, including drawing him a diagram or two. (Derek can get his economists...

Problem 2. Suppose there is only one yoga studio in town. The marginal cost of producing yoga sessions is as follows: MC=12. The yoga studio faces the following market demand function: Q=20-(1/2)P, and marginal revenue MR=40-4Q. (6 points) Calculate the profit-maximizing price, output, and profit for the yoga studio. (bonus: 3 points) Graph the market demand curve, the studio's marginal revenue and marginal cost curves, indicating profit, price, and quantity at the profit-maximizing level of output.

Suppose there are only two driveway paving companies in a small town, Asphalt Inc. and Blacktop Bros. The inverse demand curve for paving services is P = 1, 600 ? 20Q, where quantity is measured in the number of pave jobs per month and price is measured in dollars per job. The two firms have an identical marginal cost of $400 per driveway. (a) If the two firms collude and act like a monopoly, splitting the work and profits evenly,...

Example 4: Suppose that the monopolist faces a demand curve for its widgets as q = 9 - 0.2p. The firm’s marginal revenue and cost functions are: MR(q) = 45 – 10q and MC(q) = 15 + 5q. The firm’s total cost function is C(q) = 2.5q2 + 15q + 3. How many widgets should the firm produce and sell so that the monopolist can maximize its profits? How much should the firm charge to each of its customers so...
