To join the Quiet Reading Society, members pay a fixed annual fee of F, and then they can read any number of books at an extra charge P per book. Each member’s willingness to pay for Q books is P = 100 - 5Q. (Here, Q refers to the number of books a member reads completely, but partial quantities are also possible.) The club has fixed costs, but incurs no additional cost when a member checks out a book to read. What does the optimal two-part pricing scheme look like?A. It costs nothing to join the club, and then books can be read for $50 each.B. It costs $100 to join the club, and then books can be read for $5 each.C. It costs $500 to join the club, and then books can be read for $10 each.D. It costs $1,000 to join the club, and then books can be read for free.
Yummy Yummy Popcorn, Inc. sells bags of flavored popcorn in a popular mall. As shop owner and operator, you have observed that weekly popcorn sales are well-described by the demand equation: Q = 1,200 - 800P + 2.0A, where A denotes advertising weekly spending (in dollars). You are currently charging $1.50 per bag of popcorn (for which the marginal cost is $.75) and spending $500 per week on advertising. a) Compute the store’s price elasticity and advertising elasticity.

A city has two newspapers. Demand for either paper depends on its own price and the price of its rival. Demand functions for papers A and B respectively, measured in tens of thousands of subscriptions, are 21-2Pa + Pb and 21 + Pa-2Pb The marginal cost of printing and distributing an extra paper just equals the extra advertising revenue one gets from another reader, so each paper treats marginal costs as zero. Each paper maximizes its revenue assuming that the other's price is independent of its own choice of price. If the papers enter a joint operating agreement where they set prices to maximize total revenue, by how much will newspaper prices rise? (a) 3 (b) 2 (c) 0 (d) 3.5 (e) 2.5
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…
Use economic analysis to explain why the optimal amount of product safety may be less than the amount that would totally eliminate the risk of accidents and deaths. Use automobiles as an example.
Pfizer own the copyright for “Pfizer COVID Vaccine (PCV)”. The total cost of producing Q units of PCV is TC=100+50Q+0.5Q2: . The annual demand for PCV is P=300-0.2Q. Q is the number of units of PCV. The annual interest rate facing all agents in the economy is 8.75%. a. How many units of PCV should Pfizer produce? What price should Pfizer charge for one unit of PCV? Clearly explain your reasoning. b. What is TR from PCV to Pfizer? What are Pfizer’s annual profits from PCV? c. Suppose the Pfizer copyright of PCV was due to expire by 2021. Describe the new market structure that would occur if PCV entered the public domain, meaning anybody could use PCV. What would be the new price of one unit of PCV? How many units of PCV would be sold by the COVID vaccine industry?
Suppose the Boston to Philadelphia airline route is serviced by three airlines – US Airways (Firm A) and JetBlue (Firm B) and Continental (Firm C). The demand for airline travel between these two cities is Q = 150 – p. The cost function is C(Q) = 30Q. The cost function is the same for all three airlines. Assume that the three airlines are making investments in airline capacity. In other words, they are simultaneously choosing quantity. (Cournot Competition) Derive US Airways’ residual demand function given JetBlue’s output, qB, and Continental’s output, qC. What is the Marginal Revenue for US Airways? Derive US Airways reaction function Derive the market equilibrium quantity, Q*, price, p*, and Profit.
Walmart can be viewed as a first mover. Now suppose both Walmart and HEB 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 Walmart and q2is the quantity sold by HEB. To enter the market, a retailer must build a store. Two types of stores can be built: Small and Large. A Small pantry 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, the retailer can pay $175,000 to construct a Large full-service supermarket that will allow it to sell any number of units at zero marginal cost. *Assume Walmart has built a Large full-service supermarket (i.e.Walmart chooses to build a large full-service supermarket L1 at the first stage). Calculate Walmart's profit for the following cases: a.) HEB chooses not to enter N at the second stage after viewing Walmart’s…
A manufacturer of automobiles is planning a new model and wants to determine the responsiveness of demand in a number of scenarios. The demand function for the new model is given by the following function: Q = 30000 – 3P + 2000ln(PA) + Y Where Q is the quantity sold of the new model, P is the price for the new model, PA is the price of the competitor’s model and Y is the annual income of a typical purchaser. The new model price is planned to be £20,000 and the competitor is charging £25,000. The annual income of a typical purchaser is £30,000. (a) The manufacturer wishes to determine the responsiveness of the demand for the new model if the price of a competitor’s model changes. Which measure of elasticity would be appropriate to fulfil this requirement? And provide a calculation of its value.
Two businesses contribute to maintaining green spaces. Every year the companies 1 and 2 decide how much to contribute, where the joint contribution is x= x1 + x2 The spaces Greens are common so there is no rivalry. The market rents of each company depend on the quality of its infrastructure and green spaces. The utility function of firm 1 is: Z1 = Z1 + ln(x1+x2)-x1 The utility function of firm 2 is: Z2 = Z2 + 2 ln (x1+x2) - x2 Where Z1 and Z2 are constants (a)Find the best response of firm 1 based on the contribution of firm 2, R1(X2) for all x2 [0,oo) (b) Find the best response of firm 2 based on the contribution of firm 1, R2(X1) for all x1 [0,oo) (c) Find the Nash equilibrium (x1, x2) and the total contribution x = x1 + x2. (d) Is there free riding in this equilibrium? From which company? explain. (e) Determine the total Pareto efficient input level. How does it compare to the results? found in (c)? explain Question A
. The monthly demand for trotro rides in Kumasi, Ashanti depends on the price of a taxi ride, the price of a trotro ride, and the average monthly income of riders. Some consumers might choose to ride the taxi instead of the trotro, while other riders might use both forms of transportation to get to their final destination. The demand function for trotro rides is: Qd = 9,750 – 500P + 250Pj + 5INCOME, where Qd is the number of trotro rides demanded per month, P is the price of a ride, Pj is the price of a taxi ride, and INCOME is the average monthly income of riders. Suppose that P = $1.50, Pj = $4, and INCOME = $3,000. What is the monthly quantity of trotro rides demanded? What is the value of the cross-price elasticity of demand? Based on your answer, are taxi rides and trotro rides substitutes or complements? What is the value of the income elasticity of demand? Based on your answer, are taxi rides an inferior or a normal good?
