The efficiency of labels as direct shopping aids depends on how important consumers deem the labeled information to be on the time available for acquiring this information and finally on how comprehensible the information is. Information on food quality attributes that is retrieved from labels may be classified in categories such as biased versus unbiased, accurate versus inaccurate, and favorable versus unfavorable depending on how information is conveyed to the consumer and always on the consumer’s ability and willingness to process information. Caswell and Padberg (1992) provide evidence from US surveys and argue that consumers make as many as two-third sof final purchase decisions in-store. Caswell (1997) argues that the average consumer makes one major shopping trip per week, spends about one hour in the store, evaluating over15,000 products offered in a limited period of time. Parket al.(1989) argue that decision-making quality deteriorates when the shopper is under time pressure. Maggat and Viscusi(1992) argue that too much information, or information delivered in a complex format, on labels will not be used by consumers
