Understanding Demand Curves and Elasticity

The video explores the concept of demand curves with constant elasticity, specifically focusing on a curve with unit elasticity. It begins by reviewing linear demand functions and their varying elasticity, then introduces the idea of a demand curve with constant elasticity. The video explains how to draw such a curve, detailing the relationship between price and quantity movements. It concludes by summarizing the characteristics of a demand curve with constant elasticity, emphasizing its unique shape and slope.

What is the characteristic of a perfectly inelastic demand curve?

• It has a slope of 1.

• It is a horizontal line.

• It is a vertical line.

• It has a constant slope.

What is the elasticity value of a demand curve with constant unit elasticity?

• -1

• 1

• Infinity

• 0

How does a 10% decrease in price affect quantity demanded on a curve with unit elasticity?

• Quantity demanded increases by 5%

• Quantity demanded remains unchanged

• Quantity demanded increases by 10%

• Quantity demanded decreases by 10%

What does a 10% movement in price look like when the price is close to 1?

• No movement

• A movement equal to 10 units

• A small movement

• A large movement

What happens to the demand curve as the quantity approaches zero?

• It flattens out.

• It becomes steeper.

• It becomes a vertical line.

• It becomes a horizontal line.

What is the slope of the demand curve when price and quantity are equal?

• Infinity

• -1

• 1

• 0

How does the demand curve behave when both price and quantity are the same?

• The curve becomes a vertical line.

• The curve has a slope of 1.

• The curve becomes steeper.

• The curve flattens out.

What is the effect of a 10% increase in quantity when the quantity is close to 10?

• It results in no movement.

• It results in a large movement.

• It results in a movement equal to 10 units.

• It results in a small movement.

What is the general shape of a demand curve with constant elasticity of 1?

• It is a vertical line.

• It is a straight line.

• It is a curve that gets steeper as quantity decreases.

• It is a curve that flattens as quantity decreases.

What is the implication of a demand curve with constant elasticity?

• Price remains constant.

• Price changes affect quantity demanded proportionally.

• Price changes do not affect quantity demanded.

• Quantity demanded remains constant.
