What is Elasticity?
Elasticity refers to the adaptability of something to changes. It is the flexibility of something in response to changes in other circumstances or factors affecting its performance or existence.

For example, the elasticity of underwear.
The wear fits the body of certain fatness and dimensions. The grip of the elastic expands or contracts according to the dimensions and thickness of your waist or body. This ability to adapt to changes is called elasticity.
The performance of anything, whether a product or service, depends on many related circumstances or assumptions. If those circumstances or conditions change, the performance or efficiency of that product or service also gets affected. So, it is elastic to those situations.

Elasticity of Supply
Elasticity of supply is the responsiveness of supply to changes in the prices of those goods or services.Suppliers generally increase their supplies when the price of their product increases and contract their supplies when prices decrease. Further, supplies are increased to meet increased demand, and vice versa.
Elasticity of Supply is abbreviated as Es.
It is also known as price elasticity of supply (abbreviated as PES) whenever the supply is elastic to price changes.
It is also known as price elasticity of supply (abbreviated as PES) whenever the supply is elastic to price changes.
How to Calculate Elasticity of Supply
Elasticity is measured in terms of the ratio of changes in prices. It is expressed as the ratio of the percentage change in quantity supplied to the percentage change in price.
PES or ES = (%change in supply quantity)/(%change in price), i.e., the percentage change in supply quantity is compared to the percentage change in price, and their ratio is known as the PES.
Example:
Example:
Suppose the price of potatoes increases from Rs.20 to Rs.25 a kg and the resulting supply increases to 1000 kg from the previous supply of 500 kg.
Now, the elasticity in supply is calculated as follows:
PES = {(1000 - 500) / 500 x100} ÷ {(25 - 20) / 20 x 100} = {(500/500) x 100} ÷ {(5/20) x 100}
So percentage change in supply = 100 and percentage supply in price = 25
So PES = 100 ÷ 25 = 4
PES = {(1000 - 500) / 500 x100} ÷ {(25 - 20) / 20 x 100} = {(500/500) x 100} ÷ {(5/20) x 100}
So percentage change in supply = 100 and percentage supply in price = 25
So PES = 100 ÷ 25 = 4
There are 4 kinds of elasticity in supply.
- If the increase in supply is greater than the increase in prices, it is known as high elasticity of supply. (It is always greater than one (PES > 1)).
- If the increase in supply is very small compared with the increase in prices, it is known as low elasticity of supply. (It is always less than one (PES < 1)).
- If there is no change in the quantity supplied despite an increase in prices, that condition is termed non-elasticity of supply. (The ratio is always zero (PES = 0)).
- When the percentage changes in price and supply are equal, it is known as unitary elasticity. (PES = 1)
Factors Influencing Elasticity of Supply
There are many factors influencing elasticity of supply. Some of them are narrated below.- Ability: Your ability to switch over to the production of those affected goods: If you can produce the increased-price commodities, you can supply more quantities immediately.
- Time factor: The availability of time for producing those goods or procuring them from other places can also influence the supply of those goods.
- Availability of resources and factors of production: If all the factors of production are easily available to produce that commodity, you can increase the supply easily.
- Nature of commodities: Perishable goods are more elastic as compared to durable goods because of their preservation and maintenance from rot and destruction.
- Transportation facilities or mobility: If you are able to transport or move the goods easily, you can increase their supply drastically.
