✔ 最佳答案
Answer : ABecause the least excess supply is at zero price level. No one is willing to give money for providing goods or services at negative price. Therefore, negative price is meaningless and not exist. Also when the price increase, the excess supply (Qd < Qs) will also increase. So the goods should be at zero price.
