Question. Examine the effects of the following on the supply curve of a Good X.
(a) Fall in own price of Good X
(b) Rise in price of factor input producing Good X
​​​​​​​Answer: Effect on supply curve of Good X when there is a :
(a) Fall in own price of Good X: When the price of a commodity falls, it leads to reduced profit margin of the producers, forcing them to sell lesser quantity. It is called as contraction in supply. There will be movement along the same supply curve towards the origin.
(b) Rise in price of factor input producing Good X: When price of factor input producing Good X rises, profit margin of the producers fall, forcing them to produce less quantity of Good X at the given price. Supply curve will shift leftwards.

Long Questions
 
1. Distinguish between contraction of supply and decrease in supply.

CBSE Class 12 Economics Supply Worksheet 3

Contraction in supply -Supply decreases due to decrease in price.

a) Decrease in supply -when supply of a commodity falls due to factors other than price it is decrease in supply. In this case the entire supply curve shifts to the left (upward).

CBSE Class 12 Economics Supply Worksheet 1

Increase in supply -When supply of a commodity rises due to change in factors other than price. It is called increase in supply. In this case the supply curve shifts rightward.
CBSE Class 12 Economics Supply Worksheet 2
 
Question. Explain the determinants of supply.
​​​​​​​Answer: The following are the determinants of supply of a commodity.
a) Price of the commodity:- There is a positive relation between the price and its quantity supplied.
b) Technological changes:- A technological progress increases the supply of a commodity and vice-versa.
c) Input price:- An increase in input price decrease the quantity supplied and vice-versa.
d) Change in excise tax :- An increase in the excise tax decreases the supply & vice-versa
e) Change in price of related products:- An increase in the price of substitute goods decreases the price & vice-versa.
 
Question. Distinguish between change in supply and change in quantity supplied. 
​​Answer: Change in quantity supplied: - When change in supply is caused by the change in its own price of the commodity, it is called change in quantity supplied. Graphically, it leads to upward and downward movement along the supply curve.
Change in supply: When change (increase or decrease) in supply is caused by change in ‘factors other than the own price of the commodity’, it is called change in supply. It leads to rightward or leftward shift of the supply curve.
