Only one firm produces and sells soccer balls in the country of Wiknam, and as the story begins, international trade in soccer balls is prohibited. The following equations describe the monopolist's demand, marginal revenue, total cost, and marginal cost:
Demand: P = 10 - Q
Marginal Revenue:MR = 10 - 2 Q
Total Cost TC= 3 + Q+0.5 Q2
Marginal Cost: MC= 1+ Q,
where Q is quantity and Pis the price measured in Wiknamian dollars.

- The diagram above represents a monopolist firm. Answer the following questions: What price will this firm charge and what quantity produced in order to maximize profit? Explain your answer. If this firm becomes regulated and the regulatory agency want to achieve economic efficiency, what will be the price and quantity? Explain your answer. If the monopolist operates at the economic efficiency level, will he be making a profit or loss? Explain. Suppose the regulatory agency wants the monopolist to charge a price that matches what it costs to produce a unit of the good/service. What price will this be and what would be the quantity produced?

- Hi! I got stuck with my microeconomics homework. Can you please help? Here's the problem: A monopolist knows that in order to expand the quantity of output it produces from 8 to 9 units it must lower the price of its output from $2 to $1. Calculate the quantity effect and the price effect. Use these results to calculate the monopolist’s marginal revenue of producing the 9th unit. The marginal cost of producing the 9th unit is positive. Is it a good idea for the monopolist to produce the 9th unit? It is from Microeconomics: Canadian Edition by Paul Krugman; Robin Wells; Iris Au; Jack Parkinsonarrow_forwardThe diagram below shows a monopolist's marginal cost schedule and the demand curve. Find and depict the following items within the diagram and briefly explain how you found them: Price Monopoly Price Demand Marginal Revenue Total Surplus Quantity Maximising Quantity b) Draw a possible marginal cost curve for the monopolist into the diagram that is consistent with all the other curves that are already given. c) Based on the marginal cost curve that you constructed in part (b), find and highlight the monopolist's total costs at the monopoly price in the diagram. d) Briefly explain the shape of the marginal revenue curve as compared to the demand curve in the diagram.arrow_forwardOnly one firm produces and sells San Francisco Giants baseball hats in the country of NoDodgers, and as the story begins, international trade in baseball hats is prohibited.
