Which of the following is a determinant of price elasticity of supply?

• A. Availability of inputs
• B. Consumer income
• C. Number of substitutes in consumption
• D. Government regulation

Answer: (A)

Price elasticity of supply measures how quickly producers can change the quantity they produce in response to a price change. The most important factor here is the availability of inputs. If inputs like raw materials, components, or labor are readily available and can be obtained or increased quickly, firms can raise production when prices rise, leading to a higher elasticity of supply. If inputs are scarce or costly to obtain, production cannot be adjusted as easily, so the elasticity is lower. The other options relate more to demand than to supply: consumer income and the number of substitutes in consumption affect how much people buy, not how much producers can respond to price changes. Government regulation can influence supply, but the direct determinant among these choices is the availability of inputs.
