Market structure refers to the competitive environment in which the buyers and sellers of a product operate. Show
b. False Economists define a market as a place where buyers go to purchase units of a commodity.
b. False A market structure is defined in terms of the number and sizes of buyers and sellers on a market, the type of product traded on the market, the mobility of resources, and the amount of knowledge economic agents have about market conditions.
b. False If a market is perfectly competitive, then the market demand curve must be infinitely price elastic.
b. False If the firms in an industry are price takers, then every firm in the industry faces a horizontal demand curve.
b. False Firms that sell commodities on markets that are imperfectly competitive face downward-sloping demand curves.
b. False Monopoly is a market structure in which there is only one buyer of a product for which there are no close substitutes.
b. False Oligopoly is a market structure in which there are few sellers of a product and additional sellers cannot easily enter the industry.
b. False Monopsony is a market structure in which there is a single buyer of a commodity or input for which there are no close substitutes.
b. False Under perfect competition, changes in market supply do not affect market price.
b. False Commodities that sell for the same price are referred to as homogeneous.
b. False Most commodities are traded on perfectly competitive markets.
b. False The combination of product homogeneity and perfect knowledge ensure that a single price will prevail on a perfectly competitive market.
b. False Product price on a competitive market is determined by the intersection of the market demand curve with the market supply curve.
b. False If a firm in a perfectly competitive industry charges a higher price than that charged by other firms in the industry it will be unable to sell any of its output.
b. False The demand curve faced by a perfectly competitive firm is horizontal.
b. False A perfectly competitive firm's demand curve is above its marginal revenue curve.
b. False If profit maximizing firms in a perfectly competitive industry are producing 14,000 units per day, but can only sell 12,000 units per day at the current market price of $23, then the market equilibrium price must be greater than $23.
b. False If profit maximizing firms in a perfectly competitive industry will produce 14,000 units per day if the market price is $23 and consumers will purchase 14,000 units per day if the market price is $20, then the market equilibrium quantity must be greater than 14,000.
b. False The efficient market hypothesis asserts that the price of a share of a firm's stock reflects the value implied by available information about the profitability of the firm.
b. False The only choice available to a perfectly competitive firm that is producing efficiently is what price to charge in order to maximize profits.
b. False Every profit-maximizing firm should produce a level of output where marginal revenue is equal to marginal cost.
b. False A perfectly competitive firm maximizes profit by producing a level of output where marginal cost is equal to price.
b. False If a perfectly competitive firm is producing a level of output where its marginal cost is greater than market price, it should raise its price.
b. False If a perfectly competitive firm is producing a level of output where price is equal to marginal cost and greater than average variable cost, then it should cease production in the short run.
b. False The shut-down pointof a perfectly competitive firm is at the minimum point on its short-run average variable cost curve.
b. False The supply curve of a perfectly competitive firm is identical to the portion of its marginal cost curve that is above its average total cost curve.
b. False If a perfectly competitive firm is in long-run equilibrium, then it is earning an economic profit of zero.
b. False If a perfectly competitive firm is in long-run equilibrium, then market price is equal to short-run marginal cost, short-run average total cost, long-run marginal cost, and long-run average total cost.
b. False If firms in a perfectly competitive industry are earning economic profits greater than zero, then more firms will enter the industry.
b. False If more firms enter a perfectly competitive industry, market equilibrium price will increase.
b. False A perfectly competitive firm is in long-run equilibrium when all inputs are earning their opportunity costs.
b. False Depreciation of a country's currency tends to make imports more expensive.
b. False Appreciation of a country's currency tends to increase the demand for the country's exports.
b. False An increase the number of U.S. dollars required to purchase one British pound would be a depreciation of the U.S. dollar and an appreciation of the British pound.
b. False An increase in the U.S. demand for British products would tend to cause an appreciation of the British pound.
b. False A monopolist's marginal revenue is below market price.
b. False A natural monopoly is one that results from exclusive control of a crucial natural resource.
b. False All monopoly power that is based on barriers to entry is subject to decay in the long run that based on government franchise.
b. False Monopolists always make economic profits.
b. False Monopolists are price takers.
b. False If a monopolist earns $5,000 when it sells 100 units of output and $5,025 when it sells 101 units of output, then the marginal revenue of the 101st unit is $25.
b. False If a monopolist has a linear demand curve, then it has a linear marginal revenue curve.
b. False A profit-maximizing monopolist will never produce a quantity that corresponds to a point on the inelastic portion of its demand curve.
b. False A monopolist will shut down in the short run if price is everywhere less than average total cost.
b. False A monopolist that is earning a profit in the short run can be expected to earn at least as much profit in the long run.
b. False If a monopolist is in short-run equilibrium, it must be in long-run equilibrium.
b. False In general, if a perfectly competitive industry is taken over by a monopolist, it will charge a lower price and produce a larger quantity of output.
b. False When compared to perfect competition, monopoly results in a deadweight loss.
b. False The difference between the total amount that consumers would be willing to pay for a given level of consumption and the amount that they actually have to pay is called consumers' surplus.
b. False Most markets are either perfectly competitive or monopolized.
b. False If a firm is small, produces a differentiated good for which there are many close substitutes, and it is easy to enter and exit the industry, then the firm is a monopolistic competitor.
b. False Monopolistic competition is most common in the manufacturing sector.
b. False The short-run supply curve for a monopolistically competitive firm is identical to the upward-sloping portion of the firm's marginal cost curve above average variable cost.
b. False Monopolistically competitive firms are price takers.
b. False Monopolistically competitive firms face a downward-sloping demand curve.
b. False If an imperfectly competitive firm has a linear demand curve, then its marginal revenue curve has the same price intercept as its demand curve.
b. False If an imperfectly competitive firm has a linear demand curve, then its marginal revenue curve has a quantity intercept that is half that of the demand curve.
b. False As more firms enter a monopolistically competitive industry, the market supply curve shifts to the right.
b. False As firms leave a monopolistically competitive industry, the remaining firms' demand curves shift to the right and become less elastic.
b. False If a monopolistically competitive firm is in long-run equilibrium, then its short-run average total cost curve is tangent to its demand curve.
b. False A market that is monopolistically competitive will tend to have fewer firms than would be the case if the same market was perfectly competitive.
b. False Monopolistically competitive firms operate with excess capacity.
b. False In the long run, monopolistically competitive firms earn zero economic profit.
b. False Product variation is the result of quality control problems.
b. False Monopolistically competitive firms attempt to minimize selling expenses.
b. False Selling expenses include any marketing expenditures that are intended to increase the demand for a product.
b. False A firm should increase expenditures on marketing and product variation up to the point where an additional dollar spent generates a marginal revenue of no less than one dollar.
b. False One problem with the theory of monopolistic competition is that it is difficult to define a market and to identify the firms that comprise it.
b. False In most cases, a monopolistically competitive market can be adequately approximated by the perfectly competitive model or the oligopoly model.
b. False What would happen if a perfectly competitive seller raised their prices above the market price?A perfectly competitive firm is known as a price taker because the pressure of competing firms forces them to accept the prevailing equilibrium price in the market. If a firm in a perfectly competitive market raises the price of its product by so much as a penny, it will lose all of its sales to competitors.
Why a perfectly competitive firm will not charge a price which is higher or lower than the market determined price?Because buyers have complete information and because we assume each firm's product is identical to that of its rivals, firms are unable to charge a price higher than the market price.
What happens when a perfectly competitive market is in equilibrium?Competitive equilibrium is a condition in which profit-maximizing producers and utility-maximizing consumers in competitive markets with freely determined prices arrive at an equilibrium price. At this equilibrium price, the quantity supplied is equal to the quantity demanded.
How does a perfectly competitive firm decide what price to charge?Since a perfectly competitive firm must accept the price for its output as determined by the product's market demand and supply, it cannot choose the price it charges. This is already determined in the profit equation, and so the perfectly competitive firm can sell any number of units at exactly the same price.
