Final answer:
When imperfect information exists, it can be difficult for a buyer and seller to agree on a price for a property.
Step-by-step explanation:
When imperfect information exists, it can be difficult for a buyer and seller to agree on a price for a property. This is because both parties may have different assessments of the property's value due to the lack of complete information. For example, the seller may overestimate the value of the property while the buyer may underestimate it. In this case, the problem that can potentially arise is a disagreement between Broker A and Seller B on the listing price.
