If the demand for a commodity remains constant as price increases, the commodity is said to be
Perfectly price inelastic
Unit price elastic
Price elastic
Price inelastic
Correct answer is D
If the demand for a commodity remains constant as price increases, the commodity is said to be perfectly price inelastic. This means that the quantity demanded of the commodity does not change at all in response to changes in price.
Price elasticity of demand is a measure of how responsive the demand for a good or service is to changes in its price. It is calculated as the percentage change in quantity demanded divided by the percentage change in price.
A perfectly price inelastic good has an elasticity of demand of 0. This means that the quantity demanded does not change at all in response to changes in price.
Some examples of perfectly price inelastic goods include:
- Life-saving drugs
- Basic food items
- Essential services (e.g., electricity, water)
In these cases, the demand for the good is so high that even a large increase in price will not cause consumers to decrease their consumption.
