Effect on Demand Curve The effect of contraction in demand is an upward movement along the same demand curve. The effect of decrease in demand is a leftward shift in the demand curve.
Price Effect There is a negative price effect; i.e., the demand for a commodity decreases when its price rises. There is no price effect; i.e., the demand for a commodity decreases at the same price.
Reason The demand for a commodity contracts because of an increase in its price. The demand for a commodity decreases because of an unfavourable change in other factors such as increase in the price of complementary goods, decrease in the price of substitutes, etc.
Example If the demand for a commodity X falls from 200 units to 140 units because of an increase in its price from ₹15 to ₹20, then it is a case of Contraction in Demand. If the demand for a commodity X falls from 200 units to 140 units with constant price of ₹15 because of changes in other factors like decrease in the price of the substitute good, then it is a case of Decrease in Demand.
