Answer:
The answer is excess supply.
Step-by-step explanation:
Excess supply occurs when there is not a balance among prices because the good's quantity is higher than the quantity required. It means that the producers wants to sell a specific quantity of a product, but the buyers cannot get that quantity according to the predominant price.
When there is an excess supply the prices diminish, and the effect of this situation is that consumers have to purchase more and at the same time suppliers have to decrease their production.
In general terms, we can say that an excess supply does not allow that the economy can operate efficiently.
