18 pages, Consumer preferences for food produced using currently prohibited production methods matter, especially in relation to potential trade deals. We conduct four discrete choice experiments examining UK consumer attitudes for food produced using several agricultural production methods currently prohibited in the UK, including chlorine washed chicken. Our results reveal negative preferences for these forms of agricultural production methods whereas EU food safety standards are highly valued. Willingness-to-pay estimates indicate that the positive values for food safety are frequently greater than the negative values placed on prohibited food production methods. Similarly, UK country of origin was highly valued but organic production was less valued. We discuss the implications of these results and, more generally, the use of stated preference estimates in economic modelling underpinning trade negotiations.
22 pages, Many stated preference studies have shown that individuals’ attitudes play an important role in explaining their behaviour and helping to disentangle preference heterogeneity. When responses to attitudinal questions are introduced into discrete choice models, a suitable approach that corrects for potential endogeneity must be adopted. We use a discrete choice experiment to analyse the preferences of residents regarding the use of agri-environmental practices in the peri-urban area of Milan (Italy). A detailed analysis of these preferences is relevant for policymakers as farmers on the peri-urban fringe are often asked to provide environmental services to urban-dwellers. We apply a latent class model that we extend to include indicators of individuals’ attitudes towards the relationship between agriculture and the environment. Besides the application of the control function approach to deal with endogeneity, our main contribution is the use of a refutability test to check the exogeneity of the instruments in the agri-environmental setting. Our results show that attitudinal indicators help to disentangle the preference heterogeneity and that the respondents’ willingness-to-pay distribution differs according to the indicators’ values.
