To tackle the issue of imperfect information in markets, sellers can leverage techniques such as reputation, guarantees, warrantees, and service contracts to prove product quality. For instance, if you were selling emeralds or used cars, providing certification of authenticity or quality, as well as a warranty, could serve to reassure potential buyers. Conversely, when purchasing items where imperfect information is prevalent, buyers might seek assurances through these same mechanisms, as well as by relying on seller reputation.
