Price discrimination occurs when a seller charges different prices for the same product in different markets to maximize profits. For this to be effective, two fundamental conditions must hold:
- Condition (I) is correct: The product units must not be transferable between markets (preventing arbitrage). If products can be bought in a cheaper market and resold in a dearer one, the price difference cannot be sustained. For example, digital products with region-specific licenses or non-transferable tickets meet this condition.
- Condition (II) is correct: Buyers in the dearer market must not be able to access the cheaper market to purchase the product. This requires market segmentation, such as through geographic, demographic, or contractual barriers (e.g., student discounts unavailable to non-students). If buyers can easily switch markets, the seller cannot maintain higher prices in the dearer market.
Both conditions ensure market separation, making price discrimination viable. Thus, option (1) is correct.
