Definition
Adverse Selection: In insurance, adverse selection refers to a situation where individuals with a higher-than-average risk propensity, such as those with a known health condition, attempt to purchase insurance coverage at standard premium rates without disclosing pertinent risk factors. This behavior skews the risk pool, leading insurers to potentially incur higher-than-expected claims costs.
Meaning
Adverse selection disrupts the balance insurers strive to maintain in their risk pool, which ideally contains a mix of low and high-risk policyholders to statistically minimize overall insurance costs. If not properly managed, adverse selection can lead to significant financial strain for insurance companies, requiring adjustments like increased premiums for all policyholders.
Etymology
The term “adverse selection” stems from the word “adverse” (mid-14c., from Old French avers and directly from Latin adversus, past participle of advertere “turn toward”), suggesting a unfavorable or negative outcome, combined with “selection,” indicating the choice or decision made.
Background
Adverse selection is closely related to the concept of information asymmetry, where there is an imbalance in information between the buyer (applicant) and seller (insurer). Applicants, aware of their higher risks, are more likely to seek insurance, while insurers may underprice policies with insufficient information, leading to economic inefficiencies.
Key Takeaways
- Understanding Risk: Adverse selection highlights the importance of accurate risk assessment in underwriting.
- Economic Impact: It may lead to elevated claims and force insurers to raise premiums, impacting the industry and consumers.
- Mitigation: Insurers use strategies like thorough screening, medical exams, and enhanced data analytics to minimize adverse selection.
Differences and Similarities
- Differences: Adverse selection differs from moral hazard, where the insured may engage in riskier behavior post-insurance coverage.
- Similarities: Both involve information asymmetry and can lead to insurance market inefficiencies.
