If the supply curve of a good cuts the price axis in its positive range and as we extend the straight line, it cuts the quantity-axis at its negative range, the elasticity of supply for the good will be: |
Less than 1. Equal to 1. More than 1. Not defined (infinity). |
More than 1. |
The correct answer is Option (3) → More than 1. When a straight-line supply curve cuts the price axis (Y-axis) at a positive point, it means the curve starts above the origin and, if extended backward, intersects the quantity axis (X-axis) at a negative value. In such a case, a small rise in price causes a larger proportional rise in quantity supplied, because the curve is relatively flatter. Hence, the percentage change in quantity supplied is greater than the percentage change in price. Therefore, the elasticity of supply (Es) is greater than 1 — i.e., the supply is elastic. |
