Adverse Selection

Adverse selection is a situation in economics where one party in a transaction has more information than the other, often leading to an imbalance and unfavorable outcomes for one side.

Screening

A solution to the problem of adverse selection that describes the efforts of a less informed party to gather information about the more informed party. A successful screen means that it is unprofitable for bad types to mimic the behavior of good types. Any successful screen can also be used as a signal.

Signaling

A solution to the problem of adverse selection that describes an informed party’s effort to communicate her type, risk, or value to less informed parties by her actions. A successful signal is one that bad types won’t mimic. Any successful signal can also be used as a screen.
