Questions Related to supply - law of supply and price elasticity of supply

 Write True or False with a reason.
If a straight line upward sloping supply curve shoots from the X-axis, elasticity of supply $>1$.

  1. True

  2. False


Correct Option: B
Explanation:

False. When a straight line upward sloping supply curve shoots from the X-axis, elasticity of supply $({E} _{s})< 1$

Write True or False with a reason.
In the long period, elasticity of supply tends to be lower than in the short period.

  1. True

  2. False


Correct Option: B
Explanation:

False. Longer the time period, greater will be the elasticity of supply. Because, over a long period of time, more and more factors are easily available and their input can be changed to increase (or decrease) output of the commodity.

 Write True or False with a reason.
If elasticity of supply $=0$, supply curve becomes a horizontal straight line.

  1. True

  2. False


Correct Option: B
Explanation:

False. If elasticity of supply $=0$, supply curve becomes a vertical straight line parallel to Y-axis.

 Write True or False with a reason.
If a straight line upward sloping supply curve shoots from the Y-axis, elasticity of supply $< 1$.

  1. True

  2. False


Correct Option: B
Explanation:

False. When a straight line upward sloping supply curve shoots from the Y-axis, elasticity of supply $({E} _{s}>1)$

Write True or False with a reason.
${E} _{s}=1$ only if supply curve forms a $\angle {45}^{o}$ at the origin. Is it true?

  1. True

  2. False


Correct Option: B

Write True or False with a reason.
If a straight line upward sloping supply curve shoots from the origin, elasticity of supply is always equal to one.

  1. True

  2. False


Correct Option: A
Explanation:

True. When a straight line upward sloping supply curve passes through the origin (no matter what the angle it forms), the elasticity of supply is equal to one.

In a situation of perfectly elastic supply, price of the commodity tends to remain constant, no matter demand increases or decreases.

  1. True

  2. False


Correct Option: A
Explanation:

True.
The price will remain unchanged under a perfectly elastic supply curve, no matter demand increases or decreases. This is because supply responds proportionately to the increase or decrease in demand, i.e., it only changes on the quantity axis, while, it is static on the price axis at a given price.

The responsiveness of the sellers to a particular change in the price of the commodity is termed as ___________. 

  1. elasticity of supply

  2. theory of demand

  3. theory of supply

  4. none of the above


Correct Option: A

The concept of elasticity of supply is a parallel concept to the concept of __________.

  1. theory of demand

  2. theory of supply

  3. elasticity of demand

  4. none of the above


Correct Option: C

The elasticity of supply is _________ when the change in the amount of supply is in exact proportion to the change in price.

  1. perfectly elastic

  2. perfectly inelastic

  3. unitary

  4. less elastic


Correct Option: C
