Discrete choice experiments: design software and two-stage choice models KU Leuven
Discrete choice experiments (DCE's) are commonly used to elicit preferences from decision makers. This thesis contributes to designing such experiments, as well as modelling the choice data gathered by such experiments.
In the second chapter, the newly developed R-package "idefix" is presented. The latter enables users to generate optimal designs for DCE’s. Furthermore, it includes adaptive design methodology and the option to gather ...
Efficient Online Choice Experiments: incorporating screening rules in the selection of sequential choice sets. KU Leuven
When people choose between alternatives, they make trade-offs between the different characteristics of the alternatives. Discrete choice experiments are conducted to get information about these trade-offs: the respondents are confronted with choice sets consisting of a number alternatives and have to indicate their most preferred alternative.
Such experiments are often conducted online which offers the opportunity to use individually ...
Does respondent inefficiency drive hypothetical bias in discrete choice experiments for non-market goods? Hasselt University
Empirical and methodological challenges in choice experiments KU Leuven
Choice experiments (CEs) are a powerful tool to predict future market demand or to assess the impact of public and private interventions to steer choice behavior ex ante and at a low cost. This is illustrated by the growing body of literature relying on CEs. However, there are several challenges to improve preference assessments based on CEs such as the presence of hypothetical biases, the use of heuristics and the improvement of experimental ...

Design and analysis of choice experiments involving mixtures KU Leuven
Many products and services involve mixtures of ingredients, where the mixtures can be expressed as combinations of ingredient proportions, for instance, flour, water and yeast to make bread. In many cases, the result of the mixture may also depend on the way in which the mixtures are processed, such as the baking time and baking temperature for a bread. These types of variables are generally called process variables.
In mixture ...
Consumer Preferences for Mixtures Using Choice Models and Experiments KU Leuven
Quantifying consumer preferences is a key requirement for businesses and industries to be successful in today's competitive environment. One of the key marketing research tools for that purpose is choice experiments, also known as stated preference studies. In the past few decades, much research has been done on the design of choice experiments and on the analysis of the resulting data, in marketing, but also in transportation and other ...
