Methodological Advances in Food Choice Experiments and Modeling: Current Practices, Challenges, and Future Research Directions

In recent decades, discrete choice experiment research applied to food choices has grown rapidly. Empirical applications include investigations of consumer preferences and demand for various food attributes, labeling programs, novel products and applications, and new food technologies. Methodological contributions include advances in the form of new theories, elicitation methods, and modeling. This study focuses on the latter and a) reviews recent methodological contributions in the food choice experiment literature, b) examines existing knowledge gaps and, c) discusses possible future research directions.
