Increasing online sales by facilitating spillover shopping

The Internet can serve dual roles as a source of information and a shopping channel for consumers. As a source of information, it competes with traditional sources such as print and direct mail. As a shopping channel, it competes with traditional shopping formats such as brick-and-mortar retailing and catalogs. There is little research as yet, however, regarding how the use of the online channel for information can affect its use for purchasing products. Our research is aimed at filling this gap in the literature, i.e., of examining if and how the use of the Internet as a source of information can affect consumers’ willingness to shop online. We use an integrated modeling framework that simultaneously models consumers’ choice of a shopping channel from three options – brick and mortar, catalog and online – and a source of information from three options as well: newspapers and magazines, direct mail, and online.
