In cities around the country, the government provides assistance to families with low incomes to rent apartments at prices capped by the U.S. Department of Housing and Urban Development (HUD), essentially setting a price ceiling on apartments. The designated apartments tend to rent quickly, and tenants are less likely to move once they find an apartment. Assume the price ceiling is set below market equilibrium and no government subsidies are offered to landlords. What are the most likely outcomes in terms of availability of rent-controlled apartments and ongoing maintenance of rent‑controlled apartments?

The price ceiling will cause a shortage of rent‑controlled apartments and the rent‑controlled apartments will be less well maintained than apartments without rent controls.

-Which statement best explains why consumers might benefit more from monopolistic competition than perfect competition? The benefits of having more variety offsets the losses from productive and allocative inefficiencies. The balance between marginal cost and price in monopolistic competition ensures that the optimal level of output will be produced. The demand curve for a monopolistically competitive firm follows the law of demand, but the demand curve for a perfectly competitive firm does not. Monopolistic competitors will use fewer resources per unit of output than perfect competitors, so overall output will be maximized.

-The benefits of having more variety offsets the losses from productive and allocative inefficiencies.

In 2015, United Airlines and Orbitz Travel sued a 22-year-old person who created the Web site skiplagged.com aimed at helping travelers save money using a technique called "hidden‑city ticketing" (CNN Business, May 1, 2015). Hidden-city ticketing works when a passenger wants to travel nonstop between an airline's major hubs but can find a less expensive fare by booking a connecting flight. The passenger travels on the first leg of the flight and does not take the connecting flight. An example would be a passenger who wanted to travel from Houston to Denver on United Airlines. The website might find a cheaper fair available from Houston to Colorado Springs with a connection in Denver. The passenger can purchase the cheaper flight, fly the first leg, and stay in Denver. Why would an airline charge more for a single flight than one that continues onwards to another destination?Airlines are competitive and believe charging a higher price will cause the other airlines to charge higher prices as well.Airlines charge a higher price because the cost of flying nonstop requires more fuel and maintenance.Airlines charge a higher price for nonstop flights because they face little competition from other airlines that require stops at their own hubs.Airlines prefer that customers take as many flights as possible because they can charge fees for inflight services.

In 2018, two regional airline carriers, Alaska Airlines and Virgin America, agreed to merge into one larger airline under the Alaska Airlines name. Although the merger would reduce the number of airlines serving the U.S. market, and hence raise the HHI, the argument made by Alaska Airlines is that the overall airline industry would become more competitive, not less. Take a look at Alaska Airlines's and Virgin America's old route maps (they can be searched using Google) and compare them to the current Alaska Airlines route map. How might the larger airline be a more competitive player in the airline market?Because a larger airline will shift the airline market into a perfectly competitive market where every firm will be a competitive firmBecause a larger airline will shift the airline market into a monopolyBecause a larger airline can attract more customers and increase its market share to a level similar to that of other leading airlinesBecause the new HHI will be above 2,500

Because a larger airline can attract more customers and increase its market share to a level similar to that of other leading airlines

In nearly every example of demand in this book, a negative relationship exists between the market price and the quantity demanded. Why doesn't this relationship exist for a firm operating in a perfectly competitive market? Because in a perfectly competitive market, each individual firm cannot decide how much of its product to sell. The statement is not true. In a perfectly competitive market, the relationship between the market price and quantity demanded is negative. Because in a perfectly competitive market, each individual firm has some control over the price of its product. Because in a perfectly competitive market, each individual firm does not have the market power to set prices. Each individual firm is a price taker.

How can a kinked demand curve indicate that the firms in the oligopoly will continue to behave as a cartel and not have an incentive to deviate from the cartel? If the firms in the oligopoly collude to restrict output, the firms implicitly agree to increase prices if a firm in the oligopoly increases prices. If the firms in the oligopoly collude to restrict output, the firms implicitly agree to cut the quantity produced if a firm in the oligopoly cut prices. If the firms in the oligopoly collude to restrict output, the firms implicitly agree to cut prices if a firm in the oligopoly cuts prices. If the firms in the oligopoly collude to restrict output, the firms implicitly agree to increase quantity if a firm in the oligopoly increases prices.

Colorado was the first state to legalize recreational marijuana in 2012. Since then, about a dozen have followed suit, leading to a boom in the number of growers and shops selling marijuana. A problem, however, is that federal law still prohibits the sale of marijuana, though in practice, state laws have been respected. Still, many shop owners choose to conduct transactions only in cash to avoid leaving a trail of evidence from credit card transactions, which reduces the risk of prosecution but raises the risk of theft or loss. With so much retail competition and the added risk, why would so many choose to venture into this business? Business ownersare protected and believe that the risks of running a marijuana business are minimal.can earn profits from sales, given the high demand for marijuana.enjoy the risks of running a marijuana business.are competitive in nature and will do what it takes to actively compete in a growing market.

Low‑fare carriers such as Spirit, Allegiant, and Frontier have been successful at gaining market share by offering low base fares, but then charging for everything from seat assignments to snacks, to carry‑on bags. In response, the major airlines (Delta, United, and American) introduced a new fare category called Basic Economy that mimics the low‑fare competition. This new strategy allows the major airlines to avoid a prisoner's dilemma outcome byestablishing a cartel, sharing market power, and maintaining considerable control over price.continuing to charge higher prices to their more loyal flyers, while competing for low‑fare carriers' customers.setting barriers to market entry, so that low‑fare carriers cannot compete for customers with major airlines.reducing fares on all passengers and competing for every customer willing to purchase an airfare.

Why, if competitive firms are earning economic profits in the short run, are they unable to earn them in the long run? If firms are making short-run profits, consumers will no longer be willing to buy the good and enrich the firm's owners. firms will enter the industry with better technology and generate more profits in the long run. firms will exit the industry and the loss of competition will drive profits to zero in the long run. firms will enter the industry and greater competition will drive profits to zero in the long run.

firms will enter the industry and greater competition will drive profits to zero in the long run.

Suppose there are three internet service providers (ISPs) in a local market which have been around for a long time and generate healthy economic profits. Suppose that a startup fiber company enters the market. Initially, the startup captures many customers from the older ISPs but soon experiences financial problems due to the huge upfront costs associated with creating a fiber network. In order to generate more revenue, the startup decreases its price by 10%. In response, the established firms all offer price-match guarantees and an additional 5% off any matched price. The older ISPs run the price matching scheme even after the startup decides to return to its original price. Eventually, the startup goes bankrupt and the older ISPs return to the initial pricing regime. -What type of strategy did the three existing ISPs employ?tit‑for‑tatgrim triggertrembling hand triggersubgame perfection

The opioid epidemic causing a staggering number of deaths each year in the United States is largely caused by two drugs: heroin and fentanyl. Much of the heroin is supplied by several major organized Mexican cartels while the much stronger fentanyl is mostly produced in hundreds of labs (big and small) in China. The market structure for heroin can be considered as an oligopoly that operates as a monopoly. On the other hand, the fentanyl industry is less organized in terms of cartel organization and therefore more competitive. How do the differences in the organization of both industries explain why deaths from fentanyl have skyrocketed in recent years? -The organized heroin carteldoes not have barriers to market entry. The more competitive fentanyl industry has substantial barriers to entry, making fentanyl a more available drug.has the ability to control quantity and raise the prices. The more competitive fentanyl industry makes more of the drug available at a lower price.makes the drug at a lower price.

Whenever a new innovation such as a motorized hoverboard or a new rental scooter program is launched, one firm will generally enjoy market power for an initial period. However, it doesn't take long before competition enters. -Why are barriers to entry important in maintaining a monopoly?Because barriers to entry allow innovators to decrease average total cost as production increases.Because barriers to entry allow innovators to become price takers.Because barriers to entry give innovators market power and control over price.Because barriers to entry give innovators control over a significant factor of production. -Why are monopolies in a high‑tech field, such as consumer electronics, often short‑lived? Because shortly after a new electronic product appears, other firms often introduce similar, though not identical, products to compete for profits.

Assume a competitive industry is in long-run equilibrium and firms in the industry are earning zero economic profit. Now assume that production technology improves such that average total costs decline by $5 per unit. How will the industry move to a new long-run equilibrium? The decline in costs will result in economic profits in the short run. In the long run, firms will enter the market causing the price to fall until all firms only earn normal profits. In the short run, market entry will occur and the market price will fall. However, there will be so much entry into the market that firms will have losses in the long run. It will not move to a new long-run equilibrium. New firms will enter the market, which will increase the price for that good and the long-run equilibrium will remain the same. The new long-run equilibrium will be where each firm has a normal profit plus $5.

Suppose you master the art of growing herbs in your garden and sell them for a profit at the local farmer's market. Your neighbor sees your profitable business and decides to do the same. However, with less experience, your neighbor faces a much higher marginal cost curve. Assume the market for herbs operates under perfect competition. How is it possible for both you and your neighbor to sell herbs at the same price? It is not possible. Since the neighbor has a higher marginal cost curve, the neighbor has to sell the herbs at a higher price. The neighbor has more friends in the area and so has more customers. Each seller produces the herbs until marginal cost equals the market price. The neighbor has to cut resources to sell the herbs at the same price.

Each seller produces the herbs until marginal cost equals the market price.

The Environmental Protection Agency is attempting to rule on whether pollution from greenhouse gas emissions endangers public safety. Among the many greenhouse gas polluters are cows emitting methane. Economists have devised a theory to help address this issue. -Identify the statement that is true according to economic theory. If the cost of paying a pollution charge (tax on bovine methane emissions) is less than the cost of reducing pollution, the farmer will have an incentive to reduce pollution. The efficient level of pollution removal occurs where the marginal benefit of pollution removal equals the marginal cost of pollution removal; i.e., some pollution could be allowed. To maximize social welfare, all pollution should be removed. The benefit of pollution cleanup to society is always less than the cost of pollution cleanup, especially if all costs are borne by the producer (which means the farmer, but technically, the cows are doing the producing). Environmental standards regarding cow-generated methane creates strong incentives for the farmer to reduce as much as possible.

The efficient level of pollution removal occurs where the marginal benefit of pollution removal equals the marginal cost of pollution removal; i.e., some pollution could be allowed.

Economic theory states that the firm should shut down if market price falls below average variable costs at the profit maximizing output. The firm will minimize losses by stopping production when revenue is not sufficient to cover variable costs. In the business world, the decision to shut down a firm is often more complicated. Under what circumstances might a firm continue to operate when prices are below average variable costs? The firm might continue to operate if profit could be generated in the long run. The firm might continue to operate because average fixed costs are being covered, even though average variable costs are not being covered. The firm would never continue to operate when prices are below average variable cost. The firm might continue to operate because some customers would be willing to pay a higher price for the firm's product.

Suppose that a newly discovered oil reservoir spans the subsurface property of many landowners. However, if too many wells are drilled and used to pump out the oil too quickly, the oil field's water and gas pressure would drop, reducing the total recoverable oil from the reservoir. This situation may lead to a "tragedy of the commons" becauseeach landowner has an incentive to pump out too much oil too quickly, leading the reservoir to dry up prematurely.landowners' property rights over their shares of the newly discovered oil will only benefit a few landowners.high transactions costs prevent landowners from bargaining and achieving an efficient allocation of oil.the landowner who makes the discovery will pump out the oil and will not share the revenues.

Indicate whether each the following statements about taxes is true or false. a. The incidence of a tax is determined by which group (buyers or sellers) must write the check to the government.TrueFalse

False -The incidence of an excise or commodity tax is a measure of who actually bears the economic burden of a tax, not merely who writes the check to the government. If the tax is paid by producers, the value of the tax can be wholly, or in part, passed onto consumers in the form of higher prices. On the other hand, if the tax is paid by consumers, sellers may find that they must reduce the price by at least a portion of the tax. In fact, it does not matter who pays the tax, as the equilibrium quantity and price (including the tax) will still be the same.

Which situation gives the best example of a price‑taker as it pertains to perfect competition? Mary Beth grows cotton. She finds that she can always sell her entire crop at the market price. However, if she asks a price that is even slightly higher she cannot sell any of her cotton. Carol sells used furniture. Sometimes customers want to haggle with her over her prices, but she typically responds, "That's the price, hon. Take it or leave it." Bob is having trouble selling his old car. When Cindy offers him $1000 he takes it, even though it is less than he was hoping to get. The city government has set a maximum price Alice can charge for her garage apartment, so she must take that price or not rent it out at all.
