The Italian legislator has adopted several instruments to discourage undeclared work and exploitative labour in agriculture, mostly of a penal-repressive nature. Among the direct and indirect policy measures, the ‘Quality Agricultural Work Network’ represents an interesting approach to producing a ‘whitelist’ of farmers compliant with labour regulations. A law proposal intends to establish the ‘Quality Agricultural Work’ (QAW) ethical label to incentivise farmers to join the network, to which a limited percentage of farms have signed up. This study aims to investigate consumer preferences for the QAW label in the Italian fruit sector. We conducted a choice experiment on a sample of 324 consumers. Willingness to pay for ethical labels was estimated before and after information treatment was administered to evaluate the prospective effects of promotional and information campaigns. The information treatment conveyed a clear and concise message about the QAW project and its ethical label. The results show that consumers would pay a high price premium for fruit produced under fair working conditions, indicating that there may be a market space for the QAW label. Moreover, consumers perceive environmental and social sustainability claims as complementary contexts where both dimensions of sustainability are relevant.Graphical abstract
