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.
Demand shifts to the left. A decrease in demand shifts the demand curve to the left and reduces price and output. An increase in supply shifts the supply curve to the right, which reduces price and increases output. A decrease in supply shifts the supply curve to the left, which raises price but reduces output.
