The supply curve of labour or the supply curve of hours worked is the mirror image of the demand curve for leisure. Here p 0 is the original equilibrium price and q 0 is the equilibrium quantity. The market supply data of the commodity x as shown in the supply schedule is now presented graphically.
In the same due to unfavorable changes in non-price factors of the commodity the production and supply have fallen to Q 1 amount.
The original demand curve is D and the supply is S. Accordingly the supply curve has shifted leftwards and new supply curve S 1 S 1 has formed. This has caused the supply curve rightwards and new supply curve S 2 S 2 has formed. When the seller moves from left to right upward the price of X increases and Q x also increases it is called extension of supply.
