Answer:
Fall; Can not be determined
Step-by-step explanation:
Fall; Can not be determined
The fall in the prices of commodities in future will result in a decrease in demand at present and the seller will try to sell at the highest possible price so it will increase the supply. Resulting, the demand curve will shift leftwards and the supply curve will shift rightwards. But, the magnitude of shift in supply curve will decide the quantity. So, quantity can be increased or decreased. Thus prices will fall but quantity can not be determined.
