The Impact of the Internet on Shopping Behavior: Modeling the Choice of Pre-Purchase and Purchase Modes

Fully understanding the potential transportation impacts of new (internet) and old (going to the store, catalog) shopping alternatives requires investigating the adoption of the various alter­na­tives. By now, numerous studies have analyzed (intended or actual) purchase or pre-purchase (search) behavior, but we are not aware of any empirical studies considering the combined choices of pre-purchase and purchase modes. Yet it is important to understand those choices not as separate and independent, but rather as interrelated. This study continues the substantive analysis of data collected from an original survey of shopping attitudes and behavior, in this phase investigating the combined choices of pre-purchase and purchase modes (primarily store and internet, but also catalog and other pre-purchase modes). We propose to (1) cluster cases based on a variety of possible pre-pur­chase/purchase mode patterns; (2) conduct descriptive analyses of the resulting clusters, using the large variety of personality, attitudinal, situational, and sociodemographic variables available to us; and (3) develop multivariate probit and/or multidimensional nested logit models of pre-purchase and purchase mode choice combinations. The findings will have important implications for transportation planning as well as for the retail industry.
