Definition of 'Adverse Selection'
In financial markets, adverse selection can occur when a buyer or seller has more information about the quality of an asset than the other party. This can lead to the uninformed party paying too much for the asset or selling it for too little.
For example, suppose a used car dealer is selling a car. The dealer knows that the car has a lot of problems, but the buyer does not. The buyer may be willing to pay a high price for the car because they do not know about the problems. This is an example of adverse selection.
Adverse selection can also occur in insurance markets. An insurance company may not be able to accurately assess the risk of insuring a particular person or business. This can lead to the insurance company charging too much for insurance or refusing to insure the person or business at all.
Adverse selection can be a serious problem for financial markets. It can lead to inefficient pricing and allocation of resources. There are a number of ways to address adverse selection, such as insurance underwriting, screening, and signaling.
Insurance underwriting is the process of assessing the risk of insuring a particular person or business. Insurance companies use a variety of factors to determine the risk, such as age, health, occupation, and driving history.
Screening is the process of identifying people or businesses that are likely to be high-risk. This can be done through a variety of methods, such as credit checks, medical exams, and criminal background checks.
Signaling is the process of providing information to an insurance company that can be used to assess the risk. This can be done through a variety of methods, such as providing information about one's health, driving history, or occupation.
Adverse selection is a complex problem, but there are a number of ways to address it. By using underwriting, screening, and signaling, insurance companies can help to ensure that they are only insuring people and businesses that are a good risk.
