摘要：Abstract In a discrete choice experiment (DCE), some respondents might not attend to all presented attributes when evaluating and choosing their preferred options. Utilizing data from a {DCE} survey in Vietnam, this paper contributes to the literature on attribute non-attendance (ANA) with an investigation of the {ANA} in a developing country context. Based on a review of relevant published {ANA} studies, we find that the extent of {ANA} reported by respondents in our Vietnam case study could be potentially more serious than in developed country studies. Our econometric analysis, based on a mixed logit model, shows that respondents who ignored the attributes have different preferences from respondents who attended to the attributes. An examination of {ANA} determinants using a multivariate probit model was undertaken to gain a better understanding of reasons for the differences in the preferences of two groups of respondents. Our results confirm that the stated {ANA} could be an example of a simplifying strategy of respondents, and that respondents ignored attributes which were not relevant to their situation.
