Third-degree price discrimination is a pricing strategy wherein a seller identifies and segments different customer groups and offers each group a different price for the same product or service. This approach maximizes revenue by leveraging differences in the price elasticity of demand among the segmented groups.
Historical Context
Price discrimination, in its various forms, has been a part of economic practices since ancient times. The term “third-degree price discrimination” was formally conceptualized by economist Arthur Pigou in the early 20th century. Pigou’s work built on the earlier theories of monopolistic pricing and provided a structured framework to understand how firms could segment their markets to enhance profitability.
Types of Price Discrimination
- First-Degree Price Discrimination: Charging each customer their maximum willingness to pay.
- Second-Degree Price Discrimination: Charging different prices based on the quantity consumed or the version of the product.
- Third-Degree Price Discrimination: Charging different prices to distinct groups based on identifiable characteristics.
Key Events in Price Discrimination
- Early 20th Century: Formalization of the concept by Arthur Pigou.
- Late 20th Century: Rise of data analytics and CRM systems that enable better identification of customer segments.
- 21st Century: Proliferation of digital platforms and dynamic pricing models that optimize third-degree price discrimination.
Detailed Explanation
Third-degree price discrimination divides customers into groups based on observable characteristics. Examples include student discounts, senior citizen rates, and geographic pricing. It is effective only when:
- Resale between different customer segments is costly or impossible.
- The seller has the ability to identify and separate customer groups effectively.
- Different groups exhibit different elasticities of demand.
Mathematical Model
Let’s denote the demand function for each segment as \( Q_i(P_i) \), where \( i \) represents different segments, and \( P_i \) is the price for segment \( i \).
The total profit, \( \Pi \), can be expressed as:

Importance and Applicability
Third-degree price discrimination is crucial for:
- Maximizing Revenue: By tapping into different consumer surplus levels.
- Market Segmentation: Allows targeting of specific groups effectively.
- Resource Allocation: Helps in better allocation of marketing and operational resources.
Examples
- Airlines: Offer discounts to students and senior citizens.
- Software Companies: Provide educational licenses at reduced rates.
- Museums and Cinemas: Offer lower prices for children, students, and seniors.
Considerations
- Legal Restrictions: Price discrimination is subject to anti-trust laws and regulations.
- Consumer Perception: If not managed well, it can lead to negative consumer perception.
- Operational Complexity: Requires robust data management and segment identification systems.
Related Terms
- Price Elasticity of Demand: Measures the responsiveness of quantity demanded to price changes.
- Monopolistic Pricing: Pricing strategies utilized by monopolistic firms.
- Dynamic Pricing: Real-time price adjustment based on market demand.
Comparisons
- Versus First-Degree: Third-degree is less complex and easier to implement but may yield lower revenue.
- Versus Second-Degree: More straightforward in terms of identification but less flexible than quantity-based pricing.
Interesting Facts
- Movie theaters often use third-degree price discrimination to offer lower prices for matinee shows targeting different demographic segments.
- This pricing strategy is prevalent in public transportation systems worldwide, with different rates for locals and tourists.
Inspirational Stories
Cinemas, by offering student discounts, managed to significantly increase weekday attendance, capturing a segment that would otherwise be unwilling to pay full price, thereby increasing overall revenue.

Summary
Third-degree price discrimination allows businesses to maximize revenue by tailoring prices to specific customer segments based on identifiable characteristics. This strategy relies heavily on the ability to segregate customer groups effectively and ensure that resale between segments is infeasible. When implemented wisely, it can enhance profitability while meeting the needs of diverse consumer groups.
