For each of the following situations, do the following: first describe whether it is a situation of moral hazard or of adverse selection. Then explain what inefficiency can arise from this situation and explain how the proposed solution reduces the inefficiency. a. When you buy a second-hand car, you do not know whether it is a lemon (low quality) or a plum (high quality), but the seller knows. A solution is for sellers to offer a warranty with the car that pays for repair costs. b. Some people are prone to see doctors unnecessarily for minor complaints like headaches, and health maintenance organizations do not know how urgently you need a doctor. A solution is for insurees to have to make a co-payment of a certain dollar amount (for example, $\$ 10$ ) each time they visit a health care provider. All insurees are risk-averse. c. When airlines sell tickets, they do not know whether a buyer is a business traveler (who is willing to pay a lot for a seat) or a leisure traveler (who has a low willingness to pay). A solution for a profit-maximizing airline is to offer an expensive ticket that is very flexible (it allows date and route changes) and a cheap ticket that is very inflexible (it has to be booked in advance and cannot be changed). d. A company does not know whether workers on an assembly line work hard or whether they slack off. A solution is to pay the workers "piece rates," that is, pay them according to how much they have produced each day. All workers are risk-averse, but the company is not risk-neutral. e. When making a decision about hiring you, prospective employers do not know whether you are a productive or unproductive worker. A solution is for productive workers to provide potential employers with references from previous employers.

Key Concepts

Moral Hazard

Moral hazard arises when one party changes their behavior after a transaction because they do not bear the full consequences of their actions. This hidden action or effort can lead to behavior that increases risks or inefficiencies, such as unnecessary usage of resources or reduced effort, thereby impairing the incentives for optimal performance.

Adverse Selection

Adverse selection occurs when there is asymmetric information before a transaction, and one party has private information about their quality or risk level. This imbalance can lead to market failure because high-quality or low-risk individuals may be driven out, leaving a pool of lower-quality or higher-risk participants, ultimately reducing overall market efficiency.

Signaling and Screening Mechanisms

Signaling and screening mechanisms are strategies used to mitigate the problems of information asymmetry. Signaling involves one party credibly conveying information about their quality (for example, providing warranties or references), while screening involves structuring offers or contracts (such as differentiated products or co-payments) to induce self-selection, which helps reveal hidden information about quality or risk.

Incentive Contracts

Incentive contracts are designed to align the interests of different parties by linking rewards to observable outcomes or measurable performance. These contracts help reduce inefficiencies due to moral hazard by providing direct incentives for effort or performance, yet they must be carefully designed to account for potential risk aversion among the parties involved.

Transcript

00:01 For each of the following situations, we're going to determine whether or not the situation is of moral hazard or of adverse selection.

00:09 And then we're going to look at what if inefficiencies can arise from the situation and explain how the proposed solution reduces the inefficiency.

00:17 When you buy a secondhand car, you do not know whether it's a lemon, low quality, or plum high quality.

00:23 But the seller knows.

00:24 A solution is for sellers to offer a warranty with the car that pays for repair costs.

00:30 This is adverse selection.

00:31 It is a situation of adverse selection because although the seller is aware what the car type is, she has to sell you don't.

00:39 If you are not aware of the quality of a car or you are offered, then we'll be willing to pay only the average of what a lemon and a plum are worth to you.

00:48 Therefore, the plum sellers are unable to get a price that is high enough for them to want to sell their car, even though if you are aware that you're getting a plum, then you would be willing to pay enough for them to want to sell it.

01:00 It is inefficient.

01:02 With an offer of a warranty, a seller can signal to you that she has a plum.

01:07 Offering a warranty would be very costly for them if it was a lemon.

01:11 Therefore, only sellers of plums can afford to offer a warranty.

01:16 Therefore, if you notice a car being sold with a warranty, you know it must be a plum and you're willing to pay a higher price for it.

01:24 Some people are prone to see doctors unnecessarily for minor complaints like headaches, and health maintenance organizations do not know how urgently you need a doctor.

01:32 A solution is for insurers to make a co -payment of a certain dollar amount, for example, $10, $25, whatever.

01:42 Each time they visit a health care provider.

01:44 All insurers are risk -averse.

01:47 This is moral hazard.

01:48 This is a situation of moral hazard because the insurer is not aware whether you are doing the right thing, seeing a doctor only if you're genuinely sick.

01:56 When the insurance company covers your visit fully, a person might visit his or her physician, even for minor headaches, resulting in excessively high level of claims.

02:08 The co -payment provides an incentive to visit your physician only when a person is sick enough or injured enough to be willing to make the co -payment.

02:15 Inefficiency occurs in the allocation of risk as you're bearing the risk, the risk of paying the deductible, that a person would prefer and be willing to pay the insurance company to bear.

02:26 There's some inefficiency here because even though you're only, you're more likely to only go to the doctor when you need to because you don't want to pay a copay unnecessarily.

02:35 We also have the flip side problem of people then avoiding the doctor because they can't afford the co -pay and then they're going to be avoiding the doctor or not going because they can't afford it even when they should be going.

02:49 When airlines sell tickets, they do not know whether a buyer is a business traveler who is willing to pay a lot for a seat or a leisure traveler who has a low willingness to pay.

02:58 A solution for a profit maximizing airline is to offer an expensive ticket that is very flexible...
