Service Pricing: Strategies and Value

Pricing Strategies: How Service Pricing Differs from Product Pricing

Service pricing presents unique challenges due to the variability of prices, the intangibility of services, and the difficulty in recognizing backstage costs. Unlike products, services often have a wide range of prices and quality within the same class. Service organizations use different terms to describe prices (e.g., offers, charges), which can confuse customers. Price can also be an indicator of quality, with higher prices sometimes evoking a perception of higher quality. However, pricing too low may raise questions about quality. Many services, such as restaurants, have higher total costs, including costs beyond paying suppliers.

Market Structures & Strategic Interactions

Monopolistic Competition

A market in which firms can enter freely, each producing its own brand or version of a differentiated product.

Characteristics of Monopolistic Competition

• Firms compete by selling differentiated products that are highly substitutable for one another but not perfect substitutes. In other words, the cross-price elasticities of demand are large but not infinite.
