Final answer:
To reassure buyers dealing with imperfect information, sellers can offer warranties and service contracts that provide protection against potential issues with the product.
Step-by-step explanation:
In situations where there is imperfect information about a product, sellers can take a number of steps to reassure potential buyers. One way is by offering a warranty, which is a promise to repair or replace the product within a specific time period if there are any issues. Furthermore, sellers can offer the option to purchase a service contract, for an additional fee, which covers repairs for a set period of time. This is especially common for larger purchases such as cars, appliances, and houses.
