“…The DCE data are analysed using the MXL model which is considered highly flexible and able to approximate any random utility model (McFadden and Train, 2000). Coefficients are considered randomly distributed across individuals (Ghosh et al , 2013). The MXL model has been used frequently in WTP studies for organic food (Van Loo et al , 2011; Janssen and Hamm, 2012) and is particularly valuable, requiring less restrictive behavioural assumptions than applied in conventional logit models (Illichmann and Abdulai, 2013; Balogh et al , 2016).…”

“…The ASCs are dummy coded, and price is a continuous numeric variable, in GBP. A normal distribution for the random parameters is assumed allowing the distribution of the coefficient estimate without a strict sign (Ghosh et al , 2013; Yao et al , 2014), since certain attributes (e.g. GM and high acrylamide) may not provide positive utility in comparison to the status quo.…”

Purpose Acrylamide is a common dietary exposure present in many baby foods. Evidence of acrylamide causing tumours in rodents has led to the chemical being classified as “probably carcinogenic to humans” by the International Agency for Research on Cancer. The purpose of this paper is to examine consumers’ willingness to pay (WTP) for a reduction in the acrylamide content of baby food and, therefore, a reduction in the risk of cancer. Design/methodology/approach A discrete choice experiment is conducted on UK consumers incorporating different levels of seven attributes: packaging, production method (organic, GM and conventional), acrylamide level, sugar, salt, one of five portions of fruit and vegetable per day and price. Consumer WTP for low acrylamide content is estimated using a mixed logit model. Findings The empirical results indicate consumers assign a high value to safer baby food, with low acrylamide content. The WTP premium for baby food with low acrylamide (105 per cent) is the highest of all attributes assessed. Consumers also have a preference for organic baby food, in contrast to an aversion towards GM. The study results indicate that reducing the acrylamide content in baby food is desirable for consumers. Originality/value This is the first study to estimate consumers’ WTP for reducing the acrylamide content of baby food in the UK. Existing research has been limited to examining the exposure of young children, in addition to the potential health risks.

“…Table 7 reports WTP by subsamples based on heads of cattle (<10, and >=10) and farm size (<4 ha, and >=4 ha) that reflect the size of each production unit. We chose RPL1 following goodness-of-fit tests (see Ghosh et al, 2013). The findings are consistent across both subsamples.…”

“…Also we have to know that the random parameters selected and their derived standard deviations should be significant or the model is meaningless. In the research of [30], they found MXL model with constrained triangular distribution(mean=spread) is superior to other models. Therefore, triangular distribution was chosen to be applied in this model.…”

Although mining is a path toward regional development and poverty reduction, mining area facing growing land use conflicts among mining, agricultural and conservation uses. Taking Shahejie town, a mining town in Jiangxi Province, China, as a case study, this paper tries to find out the defining element of the preferences and values that the public holds for cultivated land in mining area. This paper employed a choice experiment method to investigate public preferences and values for the agricultural land protection in mining area. We selected three ecological (flora and fauna species, air quality, water quality), two socio-economic (developing risk of agricultural land conversion, openness degree) and one monetary (willingness to pay) attributes. The data were analyzed using multinomial logit and multinomial mixed logit specifications to estimate respondents' WTP for alternative cultivated land protection plans. The results indicated that air quality and water quality are more significant determinants in influencing the public's cultivated land preferences.
