Difference between change in quantity demanded and change in quantity supplied

Supply represents how much the market can offer at different prices. In contrast, quantity supplied represents what amount of commodity producers will supply at a specific price. The supply schedule or supply curve indicates the supply of the commodity.Movement along the supply curve or change in quanity supplied: When the supply of a good rises due to rise in the price of the good alone, it is termed as an expansion of supply. When supply of a good falls due to fall in its price, it is called contraction of supply. Graphically, it means a movement along the supply curve. (adsbygoogle = window.adsbygoogle || []).push({}); In the given digram, at point OP, the supply is OQ. When price rises to OP1, supply rises to OQ1. In this case, the producer moves from A to B upwards but remains on the same supply curve. When price falls to OP2, supply falls to OQ2. The producer moves from A to C but remains on the same supply curve. Shifts in supply curve or change in supply. When at the given price, the supply of a good increases, it is called increase in supply. When at the given price, the supply decreases, it is called decrease in supply. Graphically, it means shift of supply curve. In the figure, at price OP, the supply is OQ. When there is increase in supply at the given price, the supply curve shifts to the right, If there is a decrease in supply at the given price, the supply curve shifts to the left. Thus, movement along the supply curve means expansion and contraction of supply whereas shifts in supply curve means increase and decrease in supply.

Change in quantity demanded (or movement along the demand curve) is associated with a change in the demand curve by a rise/fall in the price of the commodity. It is expressed in the form of an expansion of demand or contraction in demand. When the demand of a good rises due to a fall in the price of the good alone, it is termed as expansion of demand. When the demand of a good falls due to rise in its price, it is called as contraction in demand. Graphically, it means movement along the demand curve. At price OP, the demand is OQ. When price falls to OP2, demand rises to OQ2. In this case the consumer moves from A to B downwards but remains on the same demand curve. When price rises to OP1, demand falls to OQ1. Once again the consumer moves along the same demand curve from A to C.Change in demand (or shift in demand curve) is associated with the change in demand for a commodity caused by factors other than the price of a commodity such as price of related goods, income of the consumer etc. It is expressed in the form of an increase or decrease in demand. When at the given price, the demand of a good increases, it is called increase in demand. When at the given price, the demand decreases, it is called decrease in demand. Graphically, it means, shift of the demand curve. At price OP, the demand is OQ. When there is an increase in demand at a given price, the demand curve shifts to the right. If there is a decrease in demand at the given price, the demand curve shifts to the left. Thus, change in quantity demanded is due to a fall/rise in price while the change in demand is due to other factors than price.
