Qué es la elasticidad de demanda (tipos de elasticidad y efectos en los ingresos)
Understanding Demand Elasticity
Introduction to Demand Elasticity
- The class discusses different types of demand elasticity, emphasizing its importance for business profitability.
- Price changes can have a dual effect on revenue: increasing prices may raise income but reduce the number of customers, while lowering prices might increase sales volume but decrease per-unit revenue.
Types of Demand Elasticity
Elastic Demand
- Elastic demand occurs when price elasticity is greater than 1, indicating consumers are highly sensitive to price changes.
- A drop in price leads to a significant increase in quantity demanded; conversely, a price increase results in a substantial decrease in demand. Fashion retail exemplifies this behavior during sales.
Example Calculation
- An example illustrates how an initial demand of 1000 units at €10 can rise to 1200 units when the price drops to €9, showcasing consumer sensitivity.
- To calculate elasticity, the percentage change in quantity demanded (20%) is divided by the percentage change in price (-10%), yielding an elasticity value of -2 (absolute value = 2).
Implications for Revenue
- An elasticity greater than 1 indicates that consumers respond more than proportionately to price changes; thus, lowering prices increases total revenue.
- In scenarios where demand is elastic, reducing prices can lead to higher overall income despite lower unit prices due to increased sales volume.

Understanding Inelastic Demand
Characteristics of Inelastic Demand
- Inelastic demand occurs when the elasticity of demand is less than 1, indicating that consumers are not very sensitive to price changes. A decrease in price results in a minimal increase in quantity demanded.
- Essential products, such as gasoline, exemplify inelastic demand; even with rising prices, consumers continue purchasing due to necessity for commuting and travel.
Price Changes and Quantity Demanded
- With inelastic demand, price variations lead to smaller effects on quantity demanded. For instance, a 5% price increase may only result in a 5% decrease in quantity demanded.
- An example illustrates that if the initial demand is 1000 units at €10 and the price drops to €9, the quantity demanded might only rise to 1050 units.
Calculating Elasticity and Revenue Implications
- By applying the formula for elasticity using initial and final quantities and prices, it can be determined that an increase of 5% in quantity against a decrease of 10% in price yields an elasticity value of -0.5 (absolute value: 0.5), confirming inelastic demand.
- Revenue calculations show that with an initial income of €10,000 from selling 1000 units at €10, lowering the price leads to reduced revenue despite increased sales volume.
Strategic Pricing Decisions
- When dealing with inelastic demand, lowering prices may not be beneficial as it could lead to decreased overall revenue despite slight increases in customer numbers.
- The dual effect of reducing prices by 10% results in losing more revenue than gained from selling additional units due to low sensitivity among consumers.
Understanding Unit Elasticity
- Unit elastic demand occurs when the elasticity equals exactly one; here, any percentage change in price results directly corresponds with an equal percentage change in quantity demanded.
- It’s important to note that goods can exhibit varying elasticities along their demand curve; for example, a product may be elastic at one price point but become less elastic at another.
