According to the source, demand or supply is classified as elastic under which condition?
- The elasticity is greater than one
- The elasticity is equal to zero
- The elasticity is exactly equal to one
- The elasticity is less than one
Show answer and solution
Correct answer: A. The elasticity is greater than one
1. Table 5.1 sorts elasticity into three categories based on the size of the ratio.
2. An elastic demand or supply is one where the elasticity value is greater than one.
3. A value less than one is inelastic, and a value of exactly one is unitary, so neither describes elastic.
4. Zero elasticity is a separate extreme case, not the ordinary elastic category.
