Intrarespondent Taste Heterogeneity in Instantaneous Panel Surveys

The vast majority of discrete choice modeling (DCM) applications are now estimated on Stated Preference (SP) data, including but not limited to the field of transport research. In SP data, each respondent is faced with multiple choice situations, and recognizing this repeated choice nature of the data is a crucial modeling issue. With the increasing popularity of the Mixed Multinomial Logit (MMNL) model, most applications now rely exclusively on a random coefficients approach in dealing with the repeated choice nature of the data. Here in turn, the assumption is generally made that tastes vary across respondents, but not across observations for the same respondent. This paper will question this assumption and show that it is important to also allow for variation in tastes across replications for the same respondent.
