1 If the demand increases, and the supply remains the same, there will be a shortage. 2  This will mean the price will increase. 3  If the demand decreases, and the supply remains the same, there will be a surplus. 4  This will mean the price will go down.
As the supply decreases, prices will move higher because the product is more scarce. As supply increases, prices will move lower because the product is readily available. For instance, suppose there is a drought and wheat is in short supply.
