1. c. the cost of producing the product will not affect the elasticity of demand for a product.
When the demand curve is vertical price elasticity of demand is?
If a demand curve is perfectly vertical (up and down) then we say it is perfectly inelastic. If the curve is not steep, but instead is shallow, then the good is said to be “elastic” or “highly elastic.” This means that a small change in the price of the good will have a large change in the quantity demanded.
Is a straight demand curve elastic?
Elasticity along a straight line demand curve varies from zero at the quantity axis to infinity at the price axis. Below the midpoint of a straight line demand curve, elasticity is less than one and the firm wants to raise price to increase total revenue.
Which demand curve is perfectly inelastic?
vertical line
The demand curve for a perfectly inelastic good is depicted as a vertical line in graphical presentations because the quantity demanded is the same at any price.
How is the elasticity of a demand curve related?
Similarly, a percent change in price is just the absolute change in price divided by price. Simple arithmetic then tells us that price elasticity of demand is equal to the absolute change in quantity demanded divided by the absolute change in price, all times the ratio of price to quantity.
When is the slope of a demand curve constant?
This comparison highlights the fact that it’s important to specify the range of prices over which elasticity is calculated. Elasticity is not constant even when the slope of the demand curve is constant and represented by straight lines.
What are the different types of demand curves?
Negatively Sloped Straight Lines Demand Curves: It is evident that the value of e at any (p, q) point on a curvilinear demand curve and the value of e at the same (p, q) point on a straight line demand curve—which is a tangent to the former demand curve at the said point—are identical.
Can a parallel demand curve be iso elastic?
Parallel demand curves, it should be remembered that even if the slopes of two straight line demand curves are equal, i.e., even if the two such demand curves are parallel, they are not iso-elastic. For example, in Fig. 2.10, suppose that AB and CD are two straight line demand curves parallel to each other.
