Existing evidence suggests that preferences are affected by whether a price is presented as one all-inclusive expense or partitioned into a set of mandatory charges. To explain this phenomenon, we introduce a new mechanism whereby price partitioning affects a consumer’s perception of the secondary (i.e., nonfocal) benefits derived from a transaction. Four experiments support the hypothesis that a partitioned price increases the amount of attention paid to secondary attributes tagged with distinct price components. Characteristics of the offered secondary attributes such as their perceived value, relative importance, and evaluability can therefore determine whether price partitioning stimulates or hinders demand. Beyond its descriptive and prescriptive implications, this theory contributes to the emerging notion that pricing can transform, as well as capture, the utility of an offer.
