Adverse Selection
In economics, insurance, and risk management, adverse selection is a market situation where Information asymmetry, asymmetric information results in a party taking advantage of undisclosed information to benefit more from a contract or trade. In an ideal world, buyers should pay a price which reflects their willingness to pay and the value to them of the product or service, and sellers should sell at a price which reflects the quality of their goods and services. However, when one party holds information that the other party does not have, they have the opportunity to damage the other party by maximizing self-utility, concealing relevant information, and perhaps even lying. This opportunity has secondary effects: the party without the information may take steps to avoid entering into an unfair contract, perhaps by withdrawing from the interaction; a party may ask for higher or lower prices, diminishing the volume of trade in the market; or parties may be deterred from participatin ...
