Adverse Selection Problem

Definition

Adverse selection arises when one party in a transaction possesses superior information compared to the other, hindering equitable market participation. This informational asymmetry leads to market outcomes where less desirable participants are more likely to engage, impacting overall market health. In financial derivatives, it manifests when informed traders selectively transact with uninformed counterparties, exploiting their knowledge edge. This phenomenon poses a challenge to market efficiency and fair pricing, affecting long-term market sustainability.
