Final answer:
The price elasticity of demand can be influenced by factors such as substitutes, necessity, budget share, market category, and time frame.
Step-by-step explanation:
The price elasticity of demand measures the responsiveness of the quantity demanded to changes in price. Several factors can influence the price elasticity of demand:
- When few substitutes exist for a good: A good with few substitutes tends to have a more inelastic demand because consumers have fewer alternatives to choose from.
- The good is a necessity: Necessities tend to have more inelastic demand because consumers are less likely to reduce their consumption even if the price increases.
- The good is a large share of the consumer's budget: If a good represents a significant portion of a consumer's budget, demand is likely to be more elastic because consumers are more sensitive to price changes when a larger portion of their income is at stake.
- A broad market category of goods: Goods that are part of a broad market category tend to have more inelastic demand because consumers may perceive them as essential and have limited alternatives.
- When looking at demand in the long run: In the long run, demand tends to be more elastic as consumers have more time to adjust their behavior and find substitutes if prices change.
