Adverse selection, anti-selection, or negative selection is a term used in economics, insurance, statistics, and risk management. On the most abstract level, it refers to a market process in which bad results occur due to information asymmetries between buyers and sellers: the "bad" products or customers are more likely to be selected. A bank that sets one price for all its checking account customers runs the risk of being adversely selected against by its high-balance, low-activity (and hence most profitable) customers. Two ways to model adverse selection are with signaling games and screening games.
