The influence of attribute cutoffs on consumers' choices of a functional food
研究了消费者在选购含健康属性（如欧米伽-3）的功能性食品时，是否采用属性截断（即设定最低标准）来简化决策，发现部分消费者确实使用截断，且忽略其内生性会导致估计偏差。
Non-compensatory preferences are investigated by incorporating attribute cutoffs into models of consumer choices for food with health-related attributes (omega-3 content) that may be associated with genetic modification. We find empirical evidence that some individuals tend to use attribute cutoffs in decision-making, that incorporating these into the modelling of consumer choices significantly improves model fit, that some respondents are willing to take a utility penalty rather than eliminate an alternative when a cutoff violation occurs and that there is considerable heterogeneity in willingness to violate cutoffs. The study also provides some support to the hypothesis that ignoring cutoff endogeneity in model estimation may generate biased estimates.
