Item 1Suppose a monopolist is faced with the cost data shown in the table on the left and the demand schedule shown on the right.  a. Calculate the missing total-revenue and marginal-revenue amounts. Instructions: Enter your answers as whole numbers in the gray-shaded cells. If you are entering any negative numbers be sure to include a negative sign (−) in front of those numbers.

The table below shows the demand and total revenue for a monopolist. Fill in the "Marginal Revenue" column for the various prices and quantities. Instructions: Enter your answer as a whole number. If you are entering a negative number include a minus sign. Demand and RevenuesPrice (dollars) Quantity Demanded Total Revenue (dollars) Marginal Revenue (dollars)$250 0 $0 —225 20 4,500 $ 200 40 8,000 175 60 10,500 150 80 12,000 125 100 12,500 100 120 12,000

What is the best course of action for the firm in the short run?  It should not cut its price, but it should increase its sales by advertising. You Answered  It should increase its sales by lowering its price.   It should shut down. Correct answer  It should stay in business because it covers some of its fixed cost.

1. The table below describes the market situation of a monopolist. The first two columnsdescribe price and quantity as taken from the demand curve the monopolist faces. Thethird column provides the monopolist’s total cost of producing the given quantity.The monopoly may only produce whole units of output (no fractions of Q).Price Quantity Total Cost50 20 54049 21 56548 22 59047 23 61546 24 640a.* What is the profit maximizing quantity for the monopolist? What price will the monopolistcharge? (Hint: Add columns for total revenue, marginal revenue and marginal cost.)b.* What profit will the monopolist make, given your answer to part a.?c.

If this market is perfectly competitive (in long run equilibrium), whatwould consumer surplus be?d. If this market is perfectly competitive (in long run equilibrium), whatwould firm profit be?e.* If this market is a monopoly, what would the dead weight loss be?3. One approach to regulating monopolies has been to break the monopoly up into smallercomponent firms, as in the case of antitrust actions against the railroads in the early 1900’s.Would you recommend this approach for a natural monopoly? Discuss why or why not.IAC = MCC H$GDemandMRADBQFEFigure 134. Consider the payoff matrix for a two firm game depicted above.a.* What is the optimal outcome for the firm’s profits considered together?
