Psychological pricing aims to influence which of the following?

Psychological pricing is a pricing strategy that focuses on how customers perceive prices and the impact that perception has on their purchasing decisions. It operates on the idea that certain prices can have a psychological effect on consumers; for instance, pricing a product at $9.99 instead of $10.00 can create the impression of a significantly lower price, even though the actual difference is minimal. This technique is employed to make products appear more attractive, encouraging customers to make a purchase based on the perceived value or savings.

The other options do not accurately reflect the core aim of psychological pricing. Although psychological pricing might indirectly affect revenue and demand, its primary focus is the perception of price by customers. Additionally, it does not directly influence the cost structure of a product but instead operates within the existing cost framework to enhance consumer interest and sales.
