“…Thus, we should model not only incidence but also purchase quantity (e.g., Kim et al 2002). For example, Lee and Allenby (2013) showed how to incorporate discrete package sizes into a direct utility model. Most consumer product categories admit only a few different package sizes; for example, in the US beer market, the most common options for beer are 40, 72, or 144 fluid ounces.…”

“…Furthermore, small-sample inference, coupled with discrete demand, lends itself to the use of Bayesian estimation methods (Rossi et al 2005). Data augmentation is particularly helpful in dealing with discontinuities in demand space (Lee and Allenby 2013).…”

A Direct Utility Model for Asymmetric Complements

2013

View full text Add to dashboard Cite

A symmetric complements refer to goods where one good is more dependent on the other, yet consumers receive enhanced utility from consuming both. Examples include garden hoses and sprinklers, chips and dip, and routine versus personalized services where the former has a broader base for utility generation and the latter is more dependent on the other's presence. Measuring asymmetric effects is difficult when all that is observed are the purchase quantities present in a consumer's market basket. We propose a direct utility model with a latent decision sequence for measuring asymmetric effects that allows us to capture differential responses to cross-category purchases and inventories. Scanner panel data of milk and cereal purchases are used to investigate the presence of asymmetric complementarity, and implications are explored through counterfactual analyses involving cross-price elasticities and spillover effects of merchandising variables.
