Unplanned Buying By Supermarket Shoppers

We hypothesize three generic factors—shopper predispositions (including demographics and shopping habits), store environments, and shopping trip contexts—affect the unplanned buying cost-benefit calculus. Using panel data and a multi-level random effects Poisson model we find a high degree of within-household clustering in the number of unplanned categories in the shopping basket (for two trips by the same household, the intra-class correlation is .579). Thus, the majority of variation is across shoppers (rather than stores or trips), and partly explainable by demographics, but more by “traits” that reflect long-run shopping habits. Trip antecedents, types, and in-store experiences are also influential.
