manifest itself in the used car market? • What is agency cost? • How consumers face agency costs? • How does incomplete information about potential employees affect firms? • How does incomplete

billion Microsoft $59.9 billion IBM $53.4 billion GE $47.0 billion Intel $35.6 billion Nokia $26.5 billion Disney $26.4 billion McDonald’s $26.0 billion 15-5 Money-Back Guarantees • Firms use money-back guarantees as a means of winning customers’ trust • Money-back guarantees allow consumers to recover most of the cost of buying a product if the product proves defective 15-6 eBay Ratings • eBay is an online auction website that allows anyone to buy and sell goods • Both the buyer and seller have the ability to harm each other • eBay has succeeded only because it has created a buyer and seller rating system under which buyers and sellers mostly trust each other • eBay’s rating system not only provides buyers and sellers with information about each other, but also gives eBay users an incentive to behave honestly • eBay represents a triumph of markets over uncertainty 15-7 Hidden Information • Firms sometimes attempt to deliberately increase consumer uncertainty by hiding information • “Sound of silence” has strong applications to consumer product markets • Silence signals that the situation is very bad because if it wasn’t, the firm would have an incentive to say

when one attracts those with whom one least wants to interact 15-9 Used Cars and Adverse Selection • When buying a used car, buyers most want to attract sellers of high quality cars • Sellers would most want to part with vehicles of low quality • Current owners know their car’s quality, but prospective buyers don’t As adverse selection lowers the price of used cars, fewer used cars of high quality are sold Car’s quality Car’s value to buyer High $10,000 Low $3,000 • The price of used cars will be far below $10,000 because of adverse selections • This low price for used cars means that owners of excellent cars will be even less willing to sell them 10 15-10 Countering Adverse Selection in Used Car Markets • The cure for adverse selection is additional information • An independent mechanic can verify the car’s quality • A warranty by the seller can reduce hidden information • An association with brand names can reduce adverse selection, e.g “certified pre-owned BMW.” 11 15-11 Incomplete Information About Employee Activities • When employees make decisions for their employers, they act as agents • These agents have an interest in maximizing their own welfare, not the welfare of their employer • Agency Costs = The harm suffered by employers when employees makes decisions that help themselves but harm their employers • Agency costs arise because firms have incomplete information about their employees’ activities, e.g bribes and gifts to managers, frequent flyer miles for business travelers 12 15-12 Agency Costs and Consumers Agency costs also affect consumers: • Stockbrokers have an incentive to recommend that their customers engage in an excess amount of stock trading • Real estate agents serve their own self-interests by pushing their clients to make quick purchasing decisions • Doctors can serve their own self-interests while determining prescription drugs for their patients 13 15-13 Incomplete Information About Potential Employees • Firms don’t have complete information about potential employees and hence must guess based upon signals • Resume omission can damage job applicants • On average, job candidates who would be the happiest with the salary offered are the candidates of the lowest quality since the marketplace values them the least • Incomplete information can result in firms engaging in statistical discrimination in hiring decisions • Statistical discrimination occurs when someone is discriminated against for being in a group whose members have some undesirable quality 14 15-14 Incomplete Information About Politicians • Adverse selection contaminates most revolutions because the only types of people capable of acquiring power in revolutionary environments are those skilled at murder and betrayal • The unique success of the American Revolution is due to its escaping adverse selection • Voters always have incomplete information about presidential candidates 15 15-15 Incomplete Information About Insurance Customers • • • • • • Adverse selection creates potential problems for health insurance companies The people who most want to buy health insurance are the people whom the health insurance companies least want to insure Health insurance companies escape adverse selection by not providing coverage for preexisting conditions Unchecked adverse selection will drive healthy customers out of the market, resulting in only sickly people buying insurance Governments sometimes prevent insurance companies from fighting adverse selection Genetic testing would create tremendous adverse selection problems for the health insurance industry 16 15-16 Incomplete Information About Romantic Dates • You want to date someone with high qualities Unfortunately, the higher someone’s qualities, the better they will in the dating market and the less interest they will have in you • Uncertainty makes dating markets difficult to navigate • Dating market participants are willing to pay money to reduce uncertainty resulting in many Internet dating services • Silence can also send signals in online dating 17 15-17 Do You Know? • How brand names reduce uncertainty?
