A more thorough explanation:

Persistent price discrimination is the practice of a company offering the same or similar products to different customers at different prices, even though the cost of producing the product is the same. This can be direct, where the company charges different prices to different customers, or indirect, where the company offers special deals or discounts to certain customers.

For example, a movie theater may charge different prices for tickets based on the time of day or day of the week. They may offer discounts to students or seniors. This is an example of direct price discrimination. Another example is a car dealership offering different financing options to different customers based on their credit score. This is an example of indirect price discrimination.

Persistent price discrimination can be a problem if it reduces competition and harms consumers. It is important for companies to be transparent about their pricing practices and not engage in discriminatory behavior that violates antitrust laws.
