Lemon
History
The term lemon was initially used by George Akerlof in a paper that introduced the notion of adverse selection by using used-car markets. Akerlof used the word lemon to describe used cars of low quality that could not be differentiated by buyers from cars of higher quality upon casual inspection.
Definition
A lemon is a poor quality good being offered by certain sellers in the market that cannot be differentiated from similar high-quality goods.
