Investigate the relationship between price elasticity of demand and total expenditure on a product.
ESSAY
💡Introduction💡
The concept of price elasticity of demand plays a crucial role in determining how changes in price affect the total expenditure on a product. Price elasticity of demand measures the responsiveness of quantity demanded to a change in price. It helps businesses and policymakers understand how consumers react to price changes and how these reactions impact total expenditure on a product.
💡Price Elasticity of Demand💡
Price elasticity of demand can be categorized into three main types: elastic, inelastic, and unit elastic. When demand is elastic (Elasticity > 1), a small change in price leads to a proportionately larger change in quantity demanded. In this case, an increase in price will lead to a decrease in total expenditure, and a decrease in price will lead to an increase in total expenditure.
In contrast, when demand is inelastic (Elasticity < 1), a change in price will result in a proportionately smaller change in quantity demanded. In this scenario, an increase in price will lead to an increase in total expenditure, while a decrease in price will lead to a decrease in total expenditure.
Unitary elasticity (Elasticity = 1) occurs when the percentage change in quantity demanded is equal to the percentage change in price. In this case, total expenditure remains constant regardless of price changes.
💡Relationship between Price Elasticity and Total Expenditure💡
The relationship between price elasticity of demand and total expenditure is best illustrated through examples. For a product with elastic demand, such as luxury goods or non-essential items, a decrease in price will lead to a significant increase in quantity demanded, resulting in a large increase in total expenditure. On the other hand, an increase in price for these goods will lead to a sharp decline in quantity demanded and total expenditure.
In contrast, products with inelastic demand, such as basic necessities like food or medical supplies, will see a smaller change in quantity demanded in response to price changes. An increase in price for these goods may lead to a slight decrease in quantity demanded but an overall increase in total expenditure due to the essential nature of the product.
💡Conclusion💡
In conclusion, the price elasticity of demand plays a crucial role in determining the impact of price changes on total expenditure. Businesses can use this concept to set prices strategically to maximize revenue and profit. Understanding the relationship between price elasticity and total expenditure is essential for effective pricing strategies and market analysis.

Price Elasticity of Demand and Total Expenditure 💰
Price elasticity of demand measures how responsive the quantity demanded of a product is to changes in its price. It is calculated as the percentage change in quantity demanded divided by the percentage change in price.
1. Elastic Demand:
- When demand is elastic (elasticity greater than 1), a small change in price leads to a proportionally larger change in quantity demanded.
- Total expenditure (revenue) increases when price decreases, as the increase in quantity demanded outweighs the decrease in price.
- Example: Luxury goods, where consumers are more sensitive to price changes.
2. Inelastic Demand:
- With inelastic demand (elasticity less than 1), changes in price have a smaller impact on quantity demanded.
- Total expenditure increases when price increases, as the decrease in quantity demanded is offset by the higher price.
- Example: Necessities such as medication or basic food items.
3. Unitary Elasticity:
- When demand is unitary elastic (elasticity equal to 1), total expenditure remains constant regardless of price changes.
- Any increase in quantity demanded due to a price decrease is perfectly offset by the decrease in price.
- Example: Gasoline, where consumers may adjust their consumption slightly in response to price changes.
In conclusion, the relationship between price elasticity of demand and total expenditure on a product depends on whether demand is elastic, inelastic, or unitary elastic. Understanding this relationship is crucial for businesses to make pricing decisions that maximize revenue. 📈📉
