What is elastic demand?
Elastic demand is when consumers are very sensitive to price changes, leading to a significant decrease in quantity demanded with a small increase in price.

Study Notes
Price Elasticities of Demand
Price elasticity of demand is a measure of how responsive consumers' quantity demanded for a good or service changes with respect to changes in price. It helps businesses understand consumer behavior and determine optimal pricing strategies. There are three main types of price elasticity of demand based on consumer response to price changes: elastic demand, inelastic demand, and unit elastic demand. Additionally, there's income elasticity of demand, which measures the change in the consumption of a product due to changes in consumer income.
Elastic Demand
When demand is elastic, consumers are very sensitive to price changes. A small increase in price leads to a significant decrease in the quantity demanded. This means that if a company increases its prices slightly, it will lose many customers - a substantial reduction in revenue. Examples of products where demand tends to be more elastic include luxury goods like cars, high-end smartphones, and air travel tickets, where consumers can switch easily between brands.
Inelastic Demand
In contrast, when demand is inelastic, consumers show little sensitivity to price changes. Even though they may react negatively to price increases, the decrease in quantity demanded is only slight. An example would be essential items such as food and medicine; people need them regardless of their cost. Companies dealing with inelastic demand can raise prices without worrying too much about losing customers. However, this does not mean they can charge any amount they want since customer dissatisfaction could still lead to reduced sales over time.
Unit Elastic Demand
If demand is unit elastic, a percentage change in price results in exactly the same proportionate change in the quantity demanded. For instance, if a product's price rises by 10%, the quantity sold falls by 10%. With unit elastic demand, neither suppliers nor buyers gain from price changes because any higher revenue from the price rise would be offset by the increased cost of raw materials and labor required to produce it.
Income Elasticity of Demand
Finally, income elasticity of demand measures the responsiveness of the quantity demanded to changes in consumer income. If it's positive, as it usually is, it means quantity demanded increases more than the income increase. Conversely, if it's negative, spending decreases relative to income. These concepts help companies predict future market trends and adjust their offerings accordingly.
