AbstractDue to the increasing time presswe that they face, many consumers aze becoming more concemed about the efficiency of their shopping patterns. Retailers have recognize this trend, have improved shopping convenience by offering greater variety in product categories and making it easier for conswners to combine visits to multiple stores. However, little is known about how conswners improve the efficiency of their shopping trips, or how changes in retail supply affect the way in which consumers combine multiple purposes and destinations. Building on previous work in consumer shopping trip modeling and conjoint design theory, this paper introduces a choice-based conjoint approach to studying and modeling this phenomenon. The approach is illustrated in a case study which investigated the tendency of Dutch shoppers to combine grocery, drugstore and clothing pwchases across multiple shopping destinations. It was observed that the tendency of consumers to combine pwchases differed from category to category and also depended on category availability. In general, consumers combined considerably less pwchases than could be expected if their shopping trip planning were based pwely on travel cost minimization.2
