Answer :
Answer:
The answer is: Not reliable because consumers know less than suppliers about used car quality.
Explanation:
Predictions using the supply and demand (S&D) model are reliable when:
- companies sell identical products,
- everyone involved (suppliers and consumers) has full knowledge
- about the price and quality of the products or services being offered,
- both the suppliers and consumers are price takers (have no control to dictate prices), and
- the costs of trading are low
If one or more of these conditions are not met, then the S&D model wouldn´t work properly. In this specific case, the suppliers had much information about the quality of the used cars than their customers.
