A theoretical and empirical investigation of nutritional label use

Due in part to increasing diet-related health problems caused, among others, by obesity, nutritional labelling has been considered important, mainly because it can provide consumers with information that can be used to make informed and healthier food choices. Several studies have focused on the empirical perspective of nutritional label use. None of these studies, however, have focused on developing a theoretical economic model that would adequately describe nutritional label use based on a utility theoretic framework. We attempt to fill this void by developing a simple theoretical model of nutritional label use, incorporating the time a consumer spends reading labels as part of the food choice process. The demand equations of the model are then empirically tested. Results suggest the significant role of several variables that flow directly from the model which, to our knowledge, have not been used in any previous empirical work

Are Preferences for Food Quality Attributes Really Normally Distributed? An Analysis using Flexible Mixing Distributions

We empirically question the commonly invoked assumption of normality of taste distribution in mixed logit models with continuous random parameters. We use a WTP-space random utility discrete choice model with flexible distributions on data from two choice experiments regarding beef with nested set of quality attributes. We specifically focus on distributional features such as asymmetry, multi-modality and range of variation, and find little support for normality. Our results are robust to attribute dimensionality in experimental design. Implications of our results for practitioners in the field are discussed

Welfare Effects of Food Miles Labels

We assessed the consumer welfare effects of two generic food miles labels: carbon dioxide (CO2) emission label and number of miles label. Using data from a choice experiment, our results generally suggest that a mandatory labeling policy for either type of label would have a positive welfare effect on both informed and uninformed consumers. However, a label informing consumers about the number of miles the food product has travelled provides greater positive welfare effects than a label informing consumers about the amount of CO2 emission
