Study Notes
Price Discrimination Overview
- First-degree price discrimination charges varying prices based on individual consumer surplus; it aims to extract maximum consumer surplus.
- A two-part tariff is used to implement first-degree price discrimination, ensuring firms capture all potential consumer surplus.
Types of Price Discrimination
- Second-degree price discrimination allows firms to target consumers based on their purchasing characteristics, such as quantity, e.g., buying donuts by the dozen.
- Third-degree price discrimination occurs when firms charge different prices to different groups, often based on observed characteristics, like age or geographical location. Higher prices are set for groups with a lower price elasticity of demand.
Legal Context
- Price discrimination is regulated under the Robinson-Patman Act, which promotes market efficiency and promotes fair competition among sellers.
Practical Examples
- Local telephone services in North America exemplify first-degree price discrimination through varying consumer charges.
- Paying different prices for the same meal at different times of the day (e.g., lunch vs. dinner) illustrates third-degree price discrimination.
Economic Implications
- Linear pricing typically leads to maximized consumer surplus, while price discrimination strategies aim to enhance or maintain consumer welfare by providing discounts to broader consumer groups.
- Firms may implement non-linear pricing strategies to capture more surplus—known as surplus triangles—through effective first-degree price discrimination.
Market Segmentation
- Market segmentation techniques, such as offering discounts to students, represent second-degree price discrimination strategies, helping firms optimize revenue from different consumer segments.
Antitrust Considerations
- Antitrust scrutiny of price discrimination focuses on preventing unfair price differentiation that could harm consumer interests, ensuring competitive pricing in the market.
