Answer» Correct Answer - D
all of the above situation leads to increase in supply and hence a rightward shift in supply curve.
9.

Distinguish : Stock and Supply.

Answer»
PointStockSupply
MeaningStock refers to entire quantity of a commodity which is in the custody of the seller. So it is the potential supply.Supply refers to the quantity of a commodity offered for sale at a given price and at a given time and place.
DependenceStock depends on production.Supply depends on stock and price and Willingness
RelationshipStock can be greater than the supply.Supply cannot be greater than the stock. Supply can be either equal or less than the stock.
Order of existenceStock comes before supplySupply follow stock. There cannot be supply without stock.

Rare articles do not have any current production. Hence…..

11.

How does the imposition of a unit tax affects the supply curve of a firm ?

Answer» The supply curve will shift to the left as the imposition of tax on the good will reduce its profit margin due to the increase in its cost.
12.

Howe dose technological progress affect the supply curve of a frim ?

Answer» Supply curve will shift to the right due to technological progress as it will lead to the reduction in per unit cost of the commodity and hence increases its profit margin.
13.

Which one of the following is the result of increase in price of factors of production ?A. Price of the commodityB. Period of timeC. Willingess to buyD. Quantity of the commodity

Answer» Correct Answer - C

14.

Which of the following varies in the law of supply?(A) Competition(B) Natural factors(C) Number of sellers(D) None of these

Answer»

Correct option is (D) None of these

15.

Changes in cost of factors of production affect supply. Give reason.

Answer»
  • Land, labour, capital and entrepreneur are the four factors of production.
  • When rent paid to the owner of land or wages paid to the labourer, decrease, the cost of production decreases.
  • When cost of production decreases and if price remains unchanged, the profits increase. Hence, the seller is more willing to sell large quantity. Thus, supply expands when prices of factors of production fall.
  • On the contrary, if cost of production rises, the situation becomes opposite and the supply contracts.
16.

Suppose there are two producers in the producrs in the market for a commodity and their supply functions are follows: `Q_(1)` = - 30 + 3p for any price more than or equal to 10 and `Q_(1)` = 0 at any price less than 10. `Q_(2)` = - 20 +2p for any price more than or equal to 10, and `Q_(2) = 0` at any price less than 10. Find out the market supply function .

Answer» From the given supply functions, it can be seen that both the producers do not want to supply the commodity for any price less than ₹10. Hence, the market supply will be:
`Q_("Market ") = Q_(1)+ Q_(2)`
`Q_("Market")` =(-30 + 3p) + (-20 +2p)
`Q_("Market") = - 50 + 5p ` for any price more than or equal to 10 and `Q_("Market")` = 0 at any price less than 10.
Practicals on Elasticity of supply
Formula of Elasticity of Supply
Elasticity of Supply `(E_(s)) = ("Perecentage Change in Quantity Supplied")/(" Perecntage Change in Price")`
Elasticity of Supply `(E_(s)) = (Delta Q)/(DeltaP) xx (P)/(Q) " "OR" " (1)/("Solpe of Supply Curve")xx(P)/(Q)`

Expansion contraction of supplyIncrease decrease of supply
1. When factors other than price are assumed to remain constant and price varies, there occurs expansion and contraction of supply.1. Assuming price as constant if the suppiy increase/decrease due to some other factors, it is known as increase/ decrease in supply.
2. Expansion contraction occurs due to price.2. Increase decrease of supply takes place due to factors other than price.
3. Here, the supply curve remains stable, only the points on the supply curve change.3. Here, the entire supply curve shifts.

Answer» Less elastic `(Es lt 1)`. because it implies quantity supplied is less responsive to the change in price.
38.

Explain briefly how does change in supply takes place.

Answer»
  • The determinants of supply are classified under two major categories. They are:
    1. Price and
    2. Factors other than price.
  • When factors other than price are assumed to remain constant and price varies, there occurs expansion and contraction of supply.
  • When price is held constant and other factors vary, there occurs increase and decrease in supply.
39.

Explain the exceptions to the law of supply.

Answer»
  • “When all other factors affecting supply are assumed to be constant, as price increases, supply expands and as price decreases, supply contracts”. However, for some goods there are exceptions to this law.
  • Under the exceptions to law of supply, keeping other factors constant, supply of a good rises when its price falls and supply falls when price rises.

Examples of such goods are:
1. Rare goods:

  • Certain goods are rare and hence even if there is a significant rise in their prices, their supply does not rise. For example, ancient coins, ancient idols, original manuscripts, old books, ancient handicrafts etc.
  • An important point to note is that such goods are not produced on a daily basis. Hence,-it will be incorrect to consider these goods as exceptions to the law of supply. So, such goods should be kept out of the study of supply.

2. Perishable goods:

  • Highly perishable goods like milk, milk products, green vegetables, meat, eggs, fish, ripe fruits, flowers, etc. cannot be stored for a long time.
  • Hence, even if their price falls their supply will not contract because they cannot be preserved and hence must be sold.
  • In current times with availability of storing such goods in cold storages even this exception is a matter of debate.
40.

What is leftward shift of supply curve?

Answer»

Keeping price factor as constant, if supply decreases due to any other factor, the. supply curve will shift towards left which is called leftward shift in supply curve.

41.

42.

What is increase-decrease of supply?

Answer»

43.

What is rightward shift of supply curve?

Answer»

Keeping price factor as constant, if supply increases due to any other factor, the supply curve will shift towards right which is called rightward shift in supply curve.

44.

State few factors that can be responsible for rightward shift of supply curve?

Answer»

The factors responsible for rightward shift could be fall in cost of production, fall in prices of factors of production, improvement in technology, rise in number of suppliers, government policies, etc.
