Final answer:
The price elasticity of a product tends to be higher when there are more substitutes, when the period of time elapsed is shorter, and when more consumers perceive it as a necessary good.
Step-by-step explanation:
The price elasticity of a product tends to be higher when:
- The product has a greater number of substitutes, as consumers can find an alternate product instead of paying the increased price.
- The period of time elapsed is shorter, as consumers may not have enough time to adjust their purchasing behavior.
- The product is perceived as a necessary good by more consumers, as they are less likely to change their purchasing behavior even with a price increase.
