6. Conclusions
This paper presents the first alternative-specific hybrid choice model using stated preference data in the field of shopping behavior research, presenting a sophisticated modeling approach to explore the trade-offs individuals face when choosing between online and instore shopping for two distinctly different types of products: Groceries (G), a typical experience good, and standard electronic appliances (E), a typical search good.
The integrated choice and latent variable (ICLV) approach comes along with an enhanced estimation efficiency and helps to structure respondent heterogeneity via the latent variable efficiently and more intuitively. As we can show for the current application, this leads to a more behaviorally sound representation of individual decision making when comparing to the reduced form Mixed Logit model.
By including two latent variables (LVs) reflecting the attitudes towards online shopping and the pleasure of shopping, the LV structural model reveals information of individual attitudes conditional on observable socio-economic characteristics, which in turn affect the choice of the shopping channel: Given a specific target consumer segment, one can predict alternative-specific market shares and/or heterogeneity in attribute sensitivities such as shopping costs, and based on that, develop an effective retailing strategy.
