There are two movie theaters in the town of Harkinsville: Modern Multiplex (Firm 1) and Galaxy (Firm 2). The demands for each firm are: Q1 = 125 – 3.5P1 + 2P2 and Q2 = 125 – 3.5P2 + 2P1, where quantities are measured in hundreds of moviegoers. Costs per customer are: $4 for Firm 1 and $3 for Firm 2. Instructions: Use no decimals. Use the average cost to calculate monopoly profits. Do not round if values are used to complete other calculations. Use commas (30,000 instead of 30000) Complete the following table.   P1 P2 Q1 Q2 Profits F1 Profits F2 Firm 1 colludes, Firm 2 cheats w/ QDC           2,824 Firm 1 colludes, Firm 2 cheats w/ QBRF

Suppose Ring Dental is the single supplier at HRM region provide the dental service and has a market demand curve Q = 40 – P; A total cost curve given by the formula: T C = 80 - 20Q + 2Q2 Find the profit-maximizing quantity, price, and profit. Now, suppose Halifax Dental wishes to separate the market and target to two different groups of customers young and old customers, the average cost = marginal cost = 10 for both markets Young customers with elasticity = -5 and DA = 12000 - 65P Old customers with elasticity = -7 and DB = 12000 - 55P What is the profit if Halifax Dental sets the equal price for both markets? (use the average elasticity for equal price) What is the profit if Halifax Dental charges different prices for each market?

Le Jouet is a French firm, and it is the only seller of toy trains in France and Russia. Suppose that when the price of toy trains increases, Russian children more readily replace them with toy airplanes than French children. Thus, the demand for toy trains in Russia is more elastic than in France. The following graphs show the demand curves for toy trains in France (Dr) and Russia (DR) and marginal revenue curves in France (MRF) and Russia (MRR). Le Jouet's marginal cost of production (MC), depicted as the grey horizontal line in both graphs, is $12, and the resale of toy trains from Russia to France is prohibited. Assume there are no fixed costs in production, so marginal cost equals average total cost (ATC).

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
