Extremes of Price Elasticity

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price. The extremes of price elasticity are:

1. Perfectly elastic demand: This occurs when a small change in price leads to an infinite change in quantity demanded. In other words, consumers are very sensitive to changes in price and will only buy a product if it is available at a certain price. This is rare in real-world situations.

2. Perfectly inelastic demand: This occurs when a change in price has no effect on the quantity demanded. Consumers are willing to pay any price for the product, and there are no substitutes available. This is also rare in real-world situations.

Most products fall somewhere between these two extremes, with varying degrees of price elasticity. For example, luxury goods like high-end jewelry or sports cars may have a low price elasticity of demand because consumers are willing to pay a premium for these products, while basic necessities like food and clothing have a higher price elasticity of demand because consumers are more sensitive to changes in price.
