The more functionalities a good offers, the greater is its perceived quality. Equilibrium prices in standard spatial competition models depend solely on quality differences. We assume that new functionalities are more appreciated the closer a product is to a consumer's ideal variety. Prices are then increasing in functionality levels.

Furthermore, we endogenize whether consumers buy only one of two varieties (single-purchase) or both (multipurchase). Under multipurchase, there might be a hump-shaped relationship between equilibrium prices and functionality levels. Therefore, it could be optimal for each supplier to sacrifice sales and set prices so high that multipurchase is eliminated.
