INFERREDAND STATED ATTRIBUTE NON-ATTENDANCE IN FOOD CHOICE EXPERIMENTS

We review the current literature on attribute non-attendance in stated choice and use data from beef and chicken choice experiments using both inference and the respondents ’ own statements. Inference is based on panel data analysis by mixed logit models of choice with both discrete and continuous mix-tures of coefficients, and is conditional on the observed pattern of choice. Information from respondent statements on non-attendance is directly embedded in the specification of the indirect utility func-tion. Results show no clear winner between the inferential approaches, but the inference based on constrained latent class panel models better matches the observed data. Key words: attribute non-attendance, choice modeling, food choice experiments, organic beef and poultry. JEL codes: C25, D12
