Step-by-step explanation:
Differentiation parity and cost parity are two different concepts in the field of economics. Differentiation parity refers to the equalization of prices for similar products, regardless of brand or features. This means that companies must charge the same price for products that are essentially the same, ensuring fair competition. On the other hand, cost parity refers to equalizing the costs of producing goods or providing services. This could involve financial arrangements such as subsidies or tax incentives in order to make the costs equivalent for companies.
