We investigate non-attendance to choice set attributes and the accommodation of preference heterogeneity within the mixed logit model. We propose a generalisation of the mixed logit enabling the degree of skew of marginal utility distributions to be estimated. The implementation is Bayesian with...

We investigate the market in bespoke essays from commercial providers which students buy to submit at their University. We conduct choice experiments at 3 universities to investigate students’willingness to enter the market. Half of the sample reveal a willingness to buy. We identify...

We investigate whether individuals will voluntarily increase the complexity of the tasks they complete within a discrete choice experiment (DCE). We do this via a 'self selection of complexity' design in which respondents choose whether to face choice sets comprising 3, 4 or 6 alternatives. We...

This paper reports a study of UK consumer attitudes to genetically modified organisms (GMOs) in food and the extent to which these attitudes translate into willingness to pay to avoid these products. The results indicate the relative importance of different aspects of the food system in forming...

The economic value of irrigation water to horticultural producers in southern Spain is examined using a choice experiment. Marginal water values are found to be typically above those currently paid and to increase with holding size. Potential gains from trade are identified but this would entail...

This study uses mixed logit models to reconsider the findings of choice experiment surveys with a focus on heterogeneity among consumers. The motivation is that these techniques allow the researcher to segment the market better. This is critical because it is not the average attitude or...
