The firm must be able to produce to the point at which price equals marginal cost.II. The firm must be able to identify consumers with different demand for the product.III. The firm must be able to prevent resale of the item it produces and sells.A) I onlyB) III onlyC) Both I and II onlyD) Both II and III only11.For the next two problems, it may help to refer the graphs that we drew in the class notes. Suppose a market is monopolized. Suppose the demand function is P = 120 â 2Q. (This is an inverse demand function, meaning we have solved for P instead of Q). The resulting Marginal Revenue function is MR = 120 â 4Q. If the Marginal Cost function for this monopoly is MC = 2Q, find the optimal quantity Q* that this profit-maximizing monopoly should produce.A) Q = 5B) Q = 8C) Q = 10D) Q = 15E) Q = 20F) Q = 60G) Q = 12012.Using your answer from the previous question, find the price the monopolist will charge.A) P = $20B) P = $40C) P = $60D) P = $80E) P = $100F) P = $120A single-price monopolist is maximizing profit at an output rate of 1,500 units per month. At this output rate, the price that its customers are willing and able to pay is $12 per unit, average total cost is $8 per unit, and marginal cost is $7 per unit. It may be concluded that at this monthly output rate, marginal revenue isA) $7 per unit, and the monopolist earns economic profits of $6,000 per monthB) $7 per unit, and the monopolist earns economic profits of $7,500 per monthC) $8 per unit, and the monopolist earns economic losses of $6,000 per monthD) $8 per unit, and the monopolist earns economic profits of $7,500 per monthE) $12 per unit, and the monopolist earns economic profits of $6,000 per monthF) $12 per unit, and the monopolist earns economic profits of $7,500 per month16.Suppose a monopoly is going to engage in a two-part-tariff pricing strategy. The monopoly wants to charge an entry fee (E) which will cover the fixed costs of production. Suppose also that the monopolist is going to set a price so that the market will be allocatively efficient. Suppose that the market has N = 200 consumers, fixed costs are FC = $4,000, and marginal costs are constant at MC = $8. What entry fee (E) and price (P) should this monopolist charge in its two-part-tariff pricing strategy? Hint: Look in your notes to find out what price needs to be set such that the market will be allocatively efficient.A) E = $4000, P = $8B) E = $4000, P = $25C) E = $20, P = $8D) E = $20, P = $2517.Which of the following regarding a monopolist is INCORRECT?A) The monopolist is the single supplier of a good or serviceB) The monopolist constitutes the entire industryC) Only expensive products are produced by monopoliesD) There are barriers to entry that allow monopoly18.The model of perfect competition and the model of monopolistic competition differ in thatA) perfect competition assumes many buyers and sellers while monopolistic competition assumes many buyers but few sellers.B) perfect competition assumes easy entry of new firms while there are more significant barriers to entry in monopolistic competition.C) perfect competition assumes firms make zero profits in the long run and monopolistic competition assumes firms make positive profits.D) perfect competition assumes the product is homogeneous and monopolistic competition assumes the product is differentiated.19.The key feature of monopolistic competition isA) strong interdependence and collusion of the firms.B) lack of advertisement.C) product differentiation.D) the small number of firms in the industry.20.Compared with a monopolist, the demand curve faced by a monopolistically competitive firm isA) more elastic.B) more inelastic.C) perfectly elastic.D) perfectly inelastic.21.In a long-run monopolistically competitive equilibrium,A) P = ATC, and ATC is not at its minimum value.B) P = ATC, and ATC is at its minimum value.C) P > ATC, and ATC is at its minimum value.D) P > ATC, and ATC is not at its minimum value.22.The demand curve for the product of a firm in monopolistic competitionA) is the same as the market demand curve.B) is horizontal.C) is vertical.D) slopes downward.23.Compared with a perfectly competitive firm facing the same costs, long-run equilibrium for a monopolistically competitive firm will result inA) a higher price and greater output.B) a lower price and less output.C) a higher price and less output.D) a lower price and greater output.24.Which of the following products would most likely be produced in a monopolistically competitive market?A) wheatB) electricityC) diamondsD) fast food27.In a monopolistically competitive market there areA) many firms producing an identical productB) many firms producing similar but not identical productsC) many firms producing totally different productsD) few firms producing identical products28.Oligopoly is a situation when thereA) is one firm in the industry that is fairly large.B) are a few large firms in the industry.C) are too many firms in the industry and there is excess capacity.D) is one giant firm and many smaller firms forming a competitive fringe.29.A market structure characteristic that is generally unique to oligopoly isA) a large number of competing firms which offer similar but not identical productsB) perfectly inelastic demand faced by firmsC) strong interdependence among competing firmsD) firms not maximizing profits30.In general, horizontal mergers willA) increase the number of firms in an industry.B) decrease the number of firms in an industry.C) increase competition in an industry.D) reduce economic profits in an industry.31.If the United States’ largest bakery buys an agricultural firm that specializes in growing wheat, we would have an example ofA) a horizontal merger.B) a vertical merger.C) a monopoly.D) excessive product differentiation.
