Price Discrimination

Firms use price discrimination to capture consumer surplus (the difference between someone's willingness to pay and the price they pay).

Conditions needed for price discrimination

Conditions needed for price discrimination

  • The groups being discriminated between must have a different price elasticity of demand.
  • There must be a way of stopping arbitrage opportunities that arise from consumers buying cheap, and selling to those who have been charged a higher price.
  • The firm discriminating must be a price-setter.
First degree price discrimination

First degree price discrimination

  • First degree price discrimination involves a complete transfer of consumer surplus (the disparity between the price the consumer is willing to pay and the actual product price) to the producer.
  • This is because each customer is charged the very maximum they are happy and able to pay for a good or service.
  • This method is rarely used because of asymmetric information, and the difficulty of gathering information on every customer.
Second degree price discrimination

Second degree price discrimination

  • Second degree price discrimination involves charging different prices based on the quantity purchased.
  • The more you purchase, the cheaper the product.
  • This generates revenue from part of the consumer surplus that has been transferred.
  • It also rewards customers for making larger orders.
    • Bulk buying from a wholesaler like Costco may lead to cheaper prices. This is second degree price discrimination.
Third degree price discrimination

Third degree price discrimination

  • This charges different prices to customers based on which segment they are in - different age groups, geographies and industries.
    • Software companies like Balsamiq charge different prices for non-profits.
  • This is based on the idea that different segments of a market will have different price elasticity of demands. Profits are maximised when the price is set where marginal cost is equal to marginal revenue for each particular segment.
The impact of third degree price discrimination

The impact of third degree price discrimination

  • Consumers with more inelastic demand will be charged a higher price of Pa. They will receive less consumer surplus than if a firm could not segregate the two groups.

Advantages and Disadvantages of Price Discrimination

There are a number of advantages and disadvantages associated with the three types of price discrimination.

Advantages of price discrimination

Advantages of price discrimination

  • Price discrimination will lead to increased revenue for the firm. Higher profits could be reinvested and improve dynamic efficiency.
  • Price discrimination often means that those with higher incomes pay more for a good or service than those with lower incomes. This may help cross-subsidise products so that poorer people can afford them.
    • E.g Google Chromebooks in schools.
    • To decide whether this is fair and improves equality or not, we need to make a value judgement.
Disadvantages of price discrimination

Disadvantages of price discrimination

  • Price discrimination isn't allocatively efficient.
    • This is because the price is greater than marginal cost.
  • Some may argue that consumers paying a different price for the same good or service is unfair. This is more of a moral or normative judgement though.
