(DD) is a monopolist in the doorstop industry. Its total cost function C(⋅) is given by the quadratic function of output C(Q) =100 – 5Q + Q2 . The inverse demand function for doorstops P(⋅) is given by the linear function P(Q) = 55 – 2Q . Note that the marginal cost C′(Q) is not constant. (Also, it happens to be negative for 0 ≤ Q < 2.5.)

- Based on market research, a film production company in Ectenian obtains the following information about the demand and production costs of its new DVD:Demand: P = 1,000 – 10QTotal Revenue: TR = 1,000Q – 10Q2Marginal Revenue: MR = 1,000 – 20QMarginal Cost: MC = 100 + 10Qwhere Q indicates the number of copies sold and P is the price in Ectenian dollars.d. Suppose, in addition to the costs above, the director of the film has to be paid. The company is considering four options:i. A flat fee of 2,000 Ectenian dollarsii. 50 percent of the profitsiii. 150 Ectenian dollars per unit soldiv. 50 percent of the revenueFor each option, calculate the profit-maximizing price and quantity. Which, if any, of these compensation schemes would alter the deadweight loss from monopoly? ExplainConsider any market that has a demand curve given by: Qd = 240 - 2P. Where Qd is the total quantity demanded in the market, given in millions of units and P is the market price, calculated in monetary units. Imagine that there are 2 Cournot oligopolists operating in this market with Cmg = CVme = 15 and fixed monthly costs equal to 1,400. About this market, ask yourself: a) What is the profit of each of the oligopolists? b) Imagine that one of the companies managed to implement a process innovation capable of halving its Cmg and CVme, so that they would go from 15 to 7.5. This investment implies an additional monthly expense of $1,800. Discuss the statement: "If this situation occurs, the innovative company will not implement variable cost reduction, as the quantity supplied in the market will increase very little; prices will remain very close to what they are today and its profits will not increase"Suppose that only one firm, Big Foot, sells footballs in the country and international trade of footballs including both exporting and importing is prohibited by government due to Big Foot’s successful lobby. The following equations indicates Big Foot’s market demand and total cost:• Demand: P = 5-0.5Q• Total Cost: TC = 1.5 + 0.5Q + 0.25 Q2where Q is quantity (in 1000) and P is the price measured in dollars.

The inverse demand curve for paving services is ?= 2040 ―20? where quantity is measured in pave jobs per month and price is measured in dollars per job. Assume Asphalt, Inc. has a marginal cost of $100 per driveway and Blacktop Bros. has a marginal cost of $150. Answer the following questions: Determine each firm’s reaction curve and graph it. How many paving jobs will each firm produce in Cournot equilibrium? What will the market price of a pave job be?

Their bread taste the same and nobody can tell the difference. Abu has constant marginal costs of RM1 per loaf of bread. Bakar has constant marginal costs of RM2 per loaf. Fixed costs are zero for both of them. The inverse demand function for bread in Changlun is p(q) = 6 – 0.01(qA + qB), where q is the total number of loaves sold per day. Find the reaction function for Abu and Bakar. What is the Cournot Nash equilibrium number of loaves of bread for each baker?
