Background
Third-degree price discrimination refers to a pricing strategy where sellers charge different prices to different segments of customers based on observable characteristics that correlate with willingness or ability to pay. This approach enables firms to capture more consumer surplus by setting prices that are tailored to specific groups rather than a single, uniform price.
Historical Context
The theory of price discrimination has its roots in the works of early economists such as Arthur Pigou. Third-degree price discrimination specifically builds on the foundational principles of market segmentation and consumer identity, and has been extensively studied in both theoretical and empirical contexts.
Definitions and Concepts
- Price Discrimination: The strategy of charging different prices to different consumers for the same good or service, based on their willingness to pay.
- Third-Degree Price Discrimination: A form of price discrimination where consumers are divided into different groups or segments, and each segment is charged a different price.
Major Analytical Frameworks
Classical Economics
Classical economists focused on the overarching supply and demand principles but laid the groundwork for understanding how price and value could vary among consumer groups.
Neoclassical Economics
Neoclassical economic theory has refined the conditions and implications of third-degree price discrimination, often modeling consumer preferences and market dynamics to evaluate how firms maximize profits and increase exploitation of market power.
Keynesian Economics
While not directly focusing on price discrimination, Keynesian frameworks consider market imperfections and the inequities in price settings on different socioeconomic groups during economic fluctuations.
Marxian Economics
Marxian economics views price discrimination through the lens of capital exploitation, emphasizing how capitalists use market segmentation to maximize surplus extraction from labor and consumers.
Institutional Economics
Institutionalists study the roles of legal and social norms, noting how regulations and cultural factors influence the practice and acceptability of third-degree price discrimination.
Behavioral Economics
Behavioral economists investigate how actual consumer behavior deviates from rational models, revealing how biases and heuristics might affect consumer acceptance and the efficiency of third-degree price discrimination.
Post-Keynesian Economics
Post-Keynesian scholars explore price discrimination’s effect on income distribution and aggregate demand, emphasizing market asymmetries and power relations.
Austrian Economics
Austrian economists focus on the subjective nature of value and choice, investigating how individual preferences cause firms to adopt third-degree price discrimination to better serve differentiated markets.
Development Economics
In the context of development economics, third-degree price discrimination might be explored in terms of its impact on accessibility and affordability of goods and services in developing regions.
Monetarism
Monetarists might touch upon price discrimination only tangentially, emphasizing the broader monetary frameworks that shape firm pricing strategies.
Comparative Analysis
Third-degree price discrimination is distinct from other forms of price discrimination:
- First-Degree Price Discrimination: Ideal or perfect price discrimination where each consumer is charged their maximum willingness to pay.
- Second-Degree Price Discrimination: Price varies according to quantity purchased or product version—bulk discounts, for example.
Case Studies
Practical instances of third-degree price discrimination include:
- Airlines offering different priced tickets based on booking time and customer type.
- Movie theaters and museums charging less for students and seniors.
- Pharmaceuticals charging different prices in different countries based on average income levels.

Related Terms with Definitions
- First-Degree Price Discrimination: A situation where the seller charges each buyer their individual maximum willingness to pay.
- Second-Degree Price Discrimination: A strategy where prices depend on the quantity consumed or the chosen version of a product or service.
- Market Segmentation: The practice of dividing a market into distinct groups of buyers with different needs or characteristics.
- Consumer Surplus: The difference between what consumers are willing to pay and what they actually pay.
By understanding third-degree price discrimination, economists can gain deeper insights into how businesses optimize pricing strategies to accommodate diverse market segments and harvest consumer surplus.
