Definition of Adverse Selection§
Adverse selection is a situation that arises in a transaction where one party possesses information that the other does not, giving them an upper hand (or a competitive advantage). Think of it as a game of poker where one player can see the cards of everyone else while others can only guess! This typically happens in markets like insurance, where those most at risk (and most informed about that risk) are more likely to purchase coverage, leading to a skewed risk pool.
| Adverse Selection | Symmetric Information |
|---|---|
| One party knows much more than the other | Both parties have equal knowledge |
| Usually occurs in insurance markets | Frequently seen in more transparent transactions |
| Puts buyers at a potential disadvantage | Equates bargaining power for both parties |
| Often leads to higher premiums or limited coverage | Allows for better negotiation and consumer confidence |
Examples of Adverse Selection§
- Used Car Market: Sellers of âlemonâ cars (poor quality) know their carâs true condition while potential buyers do not, which might lead to buyers avoiding the market altogether.
- Insurance: Individuals with high-risk jobs (like stunt performers) are more likely to buy life insurance; hence insurance companies adjust their premiums accordingly, making the policy more expensive for everyone.
Related Terms§
- Asymmetric Information: A condition where one party knows more than another in a transaction. Itâs the reason why shady car sales happen!
- Moral Hazard: Risk that the behavior of the insured party changes after an insurance transaction occurs. (For example, if someone has car insurance, they might drive like they just got out of a Fast & Furious movie).
- Risk Pooling: Grouping individuals together to share the risk, which can mitigate adverse selectionâs effects. Think of it as a potluck dinner where everyone brings something â everyone ends up sharing!
Humorous Insight§
As the great economist Milton Friedman once said, âIf you put the federal government in charge of the Sahara Desert, in 5 years thereâd be a shortage of sand.â This perfectly illustrates how information (or lack thereof) can lead to bizarre outcomes in the market, much like adverse selection does!

Insurance companies often combat adverse selection by charging higher premiums, implementing stricter underwriting measures, and limiting coverage options.
