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.
9 pages., Via online journal., Using an agent-based model we explore the model of slavery in modern business developed by Crane (2013). Taking the Spanish agricultural sector—specifically the area of Campo de Dalías in Almería where much of Europe's vegetables are grown—as a case, we find that labour exploitation flourishes in communities of like-minded companies that do not care about mainstream norms. We confirm which socio-economic aspects of labour demand/supply lead to slavery, while challenging the assumption that markets which are dominated by few employers are more prone to exploiting workers. We find that, regarding isolation and connectedness of employers, cluster effects and intense inter-employer communication are particularly effective drivers of underpayment if the cluster is homogenous in terms of wage level and if it is isolated from law-abiding employers. This means that employers tend to confirm and reinforce each other in their illegal behaviour, thus creating enclaves in which non-standard norms prevail and worker exploitation is regarded as legitimate. On the other hand, we see that breaking the isolation of employees among each other only increases pay levels if there are law-abiding employers, pointing to the potentially beneficial role social business and entrepreneurs, state-owned companies, or public entrepreneurs could play for transforming labour conditions of entire markets.
