In many purhcase environments, consumers use information from a number of product categories prior to making a decision. These purchase siuaions create dependences in choice outcomes across categories. As such, these decisions cannot be modeled using a single-category, single-choice paradigm commonly used by researchers in marketing. We outline a conceptual framework for categorization, and then discuss three types of cross-category dependence: cross-category consideration, cross-category learning, and product bundling. We argue that the key modeling choice dependence across categories is knowledge of the goals driving consumer behavior.
