“…Among the set of articles that explicitly acknowledge and model the different stages of the consumer shopping process, a crucial distinction relates to the data and identification strategy used. A first group of articles models at least two stages, usually consideration and choice, and uses purchase data for estimation purposes (e.g., Allenby and Ginter, ; Siddarth, Bucklin, and Morrison, ; Chiang, Chib, and Narasimhan, ; Zhang, ; Goeree, ; Van Nierop et al., ; Terui, Ban, and Allenby, ). A second, smaller group of articles, also models at least two stages, but makes use of available data on each of the shopping stages by incorporating it directly in the estimation (e.g., Franses and Vriens, ; Lambrecht, Seim, and Tucker, ; Abhishek, Fader, and Hosanagar, ; Chintagunta and Lee, ; De los Santos, Hortaçsu, and Wildenbeest, ; Honka, ; Moraga‐González, Sándor, and Wildenbeest, ).…”
