Dynamic parity pricing involves setting prices in response to a competitor’s price changes while maintaining a relative price position. Company B raises Product B’s price to $3.60 after Company A increases Product A’s price to $4.00, keeping Product B’s price lower but aligned with the market leader’s adjustment. Option A (pure parity) implies matching the competitor’s price exactly, which is not the case. Option C(premium pricing) involves setting a higher price for perceived superior value, not applicable here. Option D (discount pricing) involves consistently lower prices, not a reactive adjustment. This question aligns with the Management and Marketing category, focusing on pricing strategies.
