11 pages., via online journal., Consumer surveys revealed positive attitudes towards organic wine in large consumer segments. Health, environmental and quality benefits were stated most often as drivers for purchase decisions. However, sales data show that the market share for organic wine is still far below 10% compared to the total wine market in all countries. Obviously, there is a gap between consumers’ attitudes and real purchase behaviour in daily decisions. So far, it is not clear whether there is congruence between consumers’ attitudes and their purchase behaviour and if the attitude-behaviour-gap differs among consumer segments. Consequently, the paper at hand explores the attitude-behaviour-gap with household panel data from the GfK Group by means of a cluster analysis. The results show that even though expenditure shares for organic wine were at a low level, attitudes were in line with purchase behaviour for five out of six clusters. For example, consumers who had the highest expenditure share for organic wine showed strong pro-environmental attitudes and a preference for sustainable products. Therefore, comprehensive communication about sustainability issues, which also includes social aspects, could help to further develop the organic wine market and lead to higher market shares. However, for the low-income consumer cluster, the price of organic wine seemed to be an effective barrier despite their positive attitudes towards environmentalism. Future studies need to consider that the extent of the attitude-behaviour-gap is segment specific.
9 pages., Via online journal., Lack of trust is thought to be one of the most significant barriers to the consumption of organic foods, which is an important dimension of sustainable behaviour. Building trust in organic foods is the central objective of this paper. Based on information processing models focusing on what message to transmit and how, and on the premise that to improve trust, two different dimensions (functionality and authenticity) must be managed simultaneously, this paper analyzes the comparative effectiveness of different combinations of message arguments, forms of appeal and sources on consumer trust. To this end, an experiment was designed with a total of 800 participants, in which 36 different treatments were tested. The results show strong interactions between the three variables considered and suggest that the most effective combinations for building trust are: the health argument put across by an expert, the authenticity argument transmitted by a producers’ union, the elitist argument made by an expert and lastly, the social argument transmitted by a public authority, using an emotional form of appeal in all four cases. These results serve to complete the previous literature on the subject, in which communication activities are recommended but the questions of what to say, how to say it and who should say it are not specifically addressed.
