Adverse Selection: Detailed Definition
Adverse selection is a phenomenon in the insurance market characterized by the disproportionate willingness of individuals with a higher probability of making insurance claims to purchase insurance coverage compared to those with lower risk. This market inefficiency arises because individuals possess more information about their own risk profile than the insurers. For example, individuals with severe health conditions are more likely to purchase health insurance, whereas individuals planning on traveling to dangerous areas are more likely to buy life insurance. To mitigate the risks associated with adverse selection, insurance companies adopt various strategies, such as increasing premiums, implementing strict underwriting processes, or outright denying coverage to high-risk individuals.
Key Points
- Asymmetric Information: Adverse selection occurs due to asymmetric information, where the insured party has more information about their risk level than the insurer.
- Higher Premiums: Insurers may raise premiums to compensate for the higher risk profile of the pool of insured individuals, making insurance less affordable.
- Underwriting Process: Insurers implement rigorous underwriting processes to screen applicants, evaluating their risk to determine coverage eligibility and pricing.
Examples of Adverse Selection
-
Health Insurance: Individuals with chronic illnesses or higher health risks are more likely to seek comprehensive health insurance policies, leading to higher claim payouts for insurers.
-
Life Insurance: Persons planning to visit dangerous locations or are engaged in high-risk occupations are more likely to purchase substantial life insurance policies.
-
Auto Insurance: Drivers with poor records or those living in areas with high accident rates are more likely to seek robust auto insurance coverage.
