Price Discrimination in Its Purest Form: Examples, Preconditions, Issues
In the world of economics, price discrimination is a common practice where different customers are charged different prices for the same product. This article will focus on first-degree price discrimination, a form of cross-subsidy where consumers who pay higher prices subsidize those who pay lower prices.
First-degree price discrimination is theoretically efficient, as it does not result in deadweight losses and extracts consumer surplus into producer surplus. Companies in a monopoly market, with high entry barriers and no substitutes, are more likely to succeed in first-degree price discrimination. In perfect first-degree price discrimination, the company charges each consumer their exact willingness to pay.
For instance, auctions and tender bidding are real-world examples of first-degree price discrimination. Buyers bid their maximum willingness to pay, and the seller charges each winning buyer accordingly, capturing the entire consumer surplus. Another example is personalized pricing based on data, where companies use consumer data and AI algorithms to estimate each individual's willingness to pay and set prices accordingly. Airlines and digital platforms are known to implement such strategies, charging different prices tailored to each consumer.
However, the practice of first-degree discrimination is challenging due to the lack of sufficient information about the reservation price of each customer and the challenges in preventing arbitrage. In health care, doctors may charge wealthier patients more and poorer patients less, effectively practicing personalized price discrimination based on individual ability or willingness to pay.
It's important to note that sometimes services charge different prices based on characteristics like age or usage, but these examples are often closer to third-degree discrimination (group pricing) rather than strictly first-degree. Emerging cases involve AI-powered platforms predicting exact willingness to pay, although this raises ethical and competition concerns.
To maximize profit, a monopolist producing 4 units sets a price, but can increase profits by practicing first-degree price discrimination. Demand for the product must have different price elasticities for first-degree price discrimination to be effective. Companies must also prevent arbitrage to extract the entire consumer surplus in the market.
First-degree price discrimination uses the reservation price of each consumer to set prices. Economists divide price discrimination into three categories: first-degree, second-degree, and third-degree. First-degree price discrimination is the practice of charging each customer the highest price they are willing and able to pay. Second-degree price discrimination uses purchasing volume to indicate consumer preference and willingness to buy. Third-degree price discrimination involves setting prices differently by segmenting consumers based on geographic or other non-volume variables.
In conclusion, first-degree price discrimination occurs primarily in settings where sellers can identify and enforce individualized prices, such as auctions, personalized dynamic pricing in airline tickets or digital platforms, and professional service fees tailored to individual ability to pay. Understanding this economic concept can help consumers make informed decisions and businesses optimize their pricing strategies.

Investing in industries that utilize first-degree price discrimination, such as auction houses and digital platforms, could offer potential profit opportunities due to the efficient extraction of consumer surplus into producer surplus. On the other hand, the finance sector might benefit from understanding price discrimination strategies to optimize business practices and remain competitive, especially in sectors like health care where personalized pricing based on ability or willingness to pay is common.
