| Abstract: | In the economic literature on the motivations underlying voluntary contributions to environmental public goods, little attention is granted to the way the overall objective of the environmental program is framed. A program which contributes to an increase of environmental quality can be perceived differently from a program designed to bring back the environmental quality to its original level, after it was damaged by human intervention, even if net environmental gain is equivalent in both programs. How does it impact participation rates and contribution levels? This paper addresses this issue in the context of agri-environmental contracts for biodiversity conservation. It compares farmers’ willingness to participate in two equivalent agri-environmental schemes, one being framed as part of a biodiversity offset program, the other one as a biodiversity conservation program. We demonstrate with a discrete choice experiment that biodiversity –offsets programs must offer a greater payment to enroll farmers compared to the latter. This is explained by the sensitivity of farmers to environmental issues. |

| Abstract: | A choice experiment was carried out in Scotland to assess consumers’ preferences and willingness to pay (WTP) for four popular food attributes (i.e. animal welfare, organic, local and low fat attributes) and determine whether these attributes are independent, complement or substitutes. The results showed that the majority of consumers have positive preferences and are willing to pay a price premium for the four attributes. Furthermore, the results from the interactions between attributes showed that labelling organic pork as local could significantly increase its demand. The results also show that the co-existence of animal welfare and organic/local/low fat labels is likely to generate a discounting effect on consumers’ total premium for these bundles of food attributes (i.e. these attributes are perceived by consumers as overlapping). Organic and local attributes were found to be independent. |

| Abstract: | The incidence of serial non-participation and protest responses has largely been ignored in willingness to accept (WTA) applications. This paper analyses serial non-participation with a focus on choice experiment applications using a WTA format to investigate preferences of ecosystem services providers towards incentive-based schemes. The paper addresses two main objectives. First, a review of the literature on WTA for participation in incentive-based schemes is used to identify and discuss a range of possible motives for protest responses that emerge in a WTA context. Second, drawing on choice experiment data on olive farmers’ preferences for agri-environmental scheme participation in Southern Spain, we analyse the impact on WTA estimates of censoring serial non-participation resulting from protest or high compensation requirements (very high takers) from further analysis. Using a random parameter logit model in WTA space, we find that the inclusion or exclusion of serial non-participants in the analysis can have a significant impact on marginal and total WTA estimates. Based on the findings, the paper makes recommendations on how to minimise the incidence of protest responses through survey design, regarding the identification of protesters as opposed to very high takers, and regarding the treatment of both for WTA estimation. |

| Abstract: | The China market for traceable food has developed gradually over the past decade. This study surveyed 1380 consumers in seven pilot cities designated by the Chinese Ministry of Commerce for the construction of a meat and vegetable circulation traceability system. A choice-based conjoint analysis and multinomial logit model were used to study consumer preferences and demand for traceable pork attributes. The results demonstrated that certification of traceable information was the most important characteristic, followed by appearance and traceable information. Significant heterogeneity was observed in consumer preferences for the attributes of traceable pork. Consumers’ preferences for traceable attributes were significantly influenced by age, income level, and education level. Based on these results, we suggest that the government should strengthen the promotion of scientific knowledge regarding traceability systems, and encourage and support the production of traceable food with different traceability levels and different certification types. Moreover, the development of food traceability systems should be combined with a labeling system for quality certification. |

| Abstract: | We show that a wide class of demand systems for dierentiated products, such as those generated by additive preferences, indirectly additive preferences, and Kimball-like homothetic preferences, can be given a multinomial logit foundation provided that the conditional indirect utility is nonlinear and varies with the whole price array. |

| Abstract: | With the farming population aging across the developed world, securing a new generation of agricultural producers is an important step towards overcoming global food problems. The vast majority of the existing literature on new entry to agriculture base their analysis on data obtained from existing farms and farmers, an approach not necessarily adequate because the people who actually make decisions about entry are non-farmers. In this paper, we report the results of a large-scale choice experiment conducted in Japan to investigate the willingness of the country’s non-farming population to enter the agricultural industry. The results of a random parameter logit estimation showed that, in the absence of farmland, technical support and guaranteed sales, the agricultural income required to induce entry of an average Japanese person is approximately ¥22.0M (£121,000), a level well above their present income of ¥5.4M (£29,700); however, when all three services are provided, this value drastically lowers to ¥4.6M (£25,300). In addition, a ¥1M (£5,500) increase in agricultural income raises a person’s likelihood to enter the industry by 1.6 percentage points. To the best of the authors’ knowledge, this is the first study to quantitatively investigate non-farmers’ willingness to enter the agricultural industry. |
