2. The demand and total cost functions for a monopoly firm are: Q(P) 20-0.5P TC(Q)=4-Q+0.5 Q² a) Derive the profit maximising Q₁, P, and compute the firm's profit p 'M' M b) Suppose instead a competitive industry where the MC curve is the competitive industry's supply function. Derive the competitive industry equilibrium P* and Q*. c) Drawing on a) and b), use a diagram and algebra to compare the monopoly industry and the perfectly- competitive industry outcomes in terms of a. equilibrium prices and quantities, b. economic efficiency (total economic surplus), and c. distribution in terms of consumer surplus and producer surplus
The following diagram illustrates the demand curve facing a monopoly in an industry with no economies or diseconomies of scale and no fixed costs. In the short and long run, MC = ATC. 1.) Using the point drawing tool, indicate the monopoly output and monopoly price (Monopoly) in the figure to the right. Attach the appropriate provided label. 2.) Using the rectangle drawing tool, shade in monopoly profits (Profit). Attach the appropriate provided label. 3.) Using the triangle drawing tool, shade in the "excess burden" or "welfare costs" of the monopoly (Excess burden). Attach the appropriate provided label. Note: Carefully follow the instructions above and only draw the required objects. The monopoly creates excess burden because O A. it produces where price equals marginal cost. B. it produces an inefficiently large amount of output. O C. it charges a price that is too low. D. it produces where marginal cost is positive. E. it produces where price is above marginal cost.

Please see the images of the article below and help answer questions. 1. Evaluate this statement: "Whereas a competitive firm must sell at the market price, a monopoly owns its market, so it can set its own prices. Since it has no competition, it produces at the quantity and price combination that maximizes its profits." Must a perfectly competitive firm sell at a market-clearing price? Alternatively, is the market-clearing price the profit-maximizing price that a competitive firm chooses to set? Can a monopolist set any (price, quantity) combination? 2. Evaluate this statement: "Monopolies drive progress because the promise of years or even decades of monopoly profits provides a powerful incentive to innovate. Then monopolies can keep innovating because profits enable them to make the long-term plans and finance the ambitious research projects that firms locked in competition can't dream of." Cite a counter-example to this claim in which deregulation of a monopolist led to lower…
(a) Does a monopolistically competitive firm have an incentive to produce at the level of output that minimizes the average total cost at the long run equilibrium? Explain with a diagram. (b) Suppose CLP Holdings Limited is a natural monopolist with constant marginal cost. Draw a diagram to indicate the profit-maximizing level of output, the profit-maximizing price, and the size of the profit. If the government wants to increase the market efficiency through price regulation, would you suggest the government setting the price equal to the firm’s marginal cost or its average total cost? Explain in detail with the diagram in part (i).
8. Natural monopoly analysis The following graph gives the demand (D) curve for water services in the fictional town of Streamship Springs. The graph also shows the marginal revenue (MR) curve, the marginal cost (MC) curve, and the average total cost (ATC) curve for the local water company, a natural monopolist. On the following graph, use the black point (plus symbol) to indicate the profit-maximizing price and quantity for this natural monopolist.

Check all that apply. Monopoly Outcome In order for a monopoly to exist in this case, the government must have intervened and created it. It is more efficient on the cost side for one producer to exist in this market rather than a large number of producers. The water company is experiencing economies of scale. The water company must…

(ii) Find the profit-maximizing uniform price. (iii) Now 14 – By, where B is a positive constant. Without calculating the new profit-maximizing uniform price, explain whether it is higher or lower than in (ii). suppose that Call Your Aunt starts to sell in Virginia. The demand curve is p
3. MUSEUM MONOPOLY MATH Once the museum has incurred the basic operating cost of 60 to open for the day, the average variable cost (and marginal cost) of serving each visitor is only 2. In other words, the museum's total daily operating cost function is DOC[Q] = 60 + 2Q, where Q is the number of visitors. Meanwhile, the inverse demand function for museum admission is P[Q] = 34 - Q. TIP: We used "average daily operating cost" instead of average total cost when discussing museums. a) If this museum were a commercial, profit-maximizing enterprise, then find its profit. TIP: You'll need to find Q* and P*. Even though you could answer this with a well-drawn graph, show that you can "do the math” to find the correct answer. TIP: This may sound familiar. What did you learn about drawing this graph? ☺ b) Suppose the museum manager set the price at 28, which is not the profit-maximizing price. Find its profit. For the remainder of the problem, suppose that the museum is instead a nonprofit…
