Final answer:
Price discrimination is a strategy used by firms to charge different prices to different groups of buyers. The condition that is NOT necessary for price discrimination is suspension of email.
Step-by-step explanation:
Price discrimination is a strategy used by firms to charge different prices to different groups of buyers for the same product or service. It is based on the principle of charging higher prices to buyers with a lower price elasticity of demand, and lower prices to buyers with a higher price elasticity of demand. The conditions necessary for price discrimination include:
- Two or more groups of buyers with different elasticities of demand
- Ability to segment the market and prevent arbitrage
- Monopoly power or market dominance
- Ability to identify and target different buyer groups
Therefore, the condition that is NOT necessary for price discrimination is A. suspension of email. This option is unrelated to price discrimination and is not a condition that affects the ability to charge different prices based on buyer characteristics.
