Elasticity of Supply Concepts

The video explains how producers adjust the quantity of goods supplied in response to price changes, introducing the concept of price elasticity of supply. It covers how to calculate this elasticity and distinguishes between elastic and inelastic supply. Examples illustrate these concepts, including perfectly elastic and inelastic supply scenarios, highlighting the theoretical nature of perfect elasticity.

What happens to the quantity supplied when the price of a good increases?

• It remains the same.

• It becomes zero.

• It increases.

• It decreases.

How is the price elasticity of supply calculated?

• By dividing the percentage change in price by the percentage change in quantity supplied.

• By subtracting the percentage change in price from the percentage change in quantity supplied.

• By dividing the percentage change in quantity supplied by the percentage change in price.

• By multiplying the percentage change in price and quantity supplied.

If the price of fingernail clippers drops by 50% and the quantity supplied decreases by 30%, what is the price elasticity of supply?

• 1.5

• 0.6

• 0.3

• 2.0

What characterizes an elastic supply?

• Quantity supplied is insensitive to price changes.

• Quantity supplied is highly sensitive to price changes.

• Price changes do not affect quantity supplied.

• Quantity supplied decreases regardless of price changes.

In an inelastic supply scenario, how does the quantity supplied respond to a price increase?

• It increases slightly.

• It remains unchanged.

• It decreases significantly.

• It increases significantly.

What is the price elasticity of supply if a 10% price increase leads to a 5% increase in quantity supplied?

• 2.0

• 0.5

• 0.1

• 1.0

What is a characteristic of perfectly elastic supply?

• The supply curve is vertical.

• The supply curve is upward sloping.

• The supply curve is horizontal.

• The supply curve is downward sloping.

In a perfectly inelastic supply scenario, how does the quantity supplied change with price?

• It becomes zero.

• It decreases.

• It remains constant.

• It increases.

Which of the following is an example of perfectly inelastic supply?

• A limited edition painting by a famous artist.

• A new model of smartphone.

• A seasonal fruit.

• A mass-produced toy.

What happens to the quantity supplied in a perfectly elastic supply when the price decreases?

• It doubles.

• It increases.

• It remains the same.

• It decreases to zero.
