Utility maximizing and regret minimizing models (RUM and RRM respectively) assume different decision rules, and additionally that these rules are conceptually and mathematically distinguishable. Yet, studies that pit them against each other or incorporate them into a heterogeneous decision rule...

Best-worst scaling (BWS) is an extension of the method of paired comparison to multiple choices that asks participants to choose both the most and the least attractive options or features from a set of choices. It is an increasingly popular way for academics and practitioners in social science,...

We show how to combine statistically efficient ways to design discrete choice experiments based on random utility theory with new ways of collecting additional information that can be used to expand the amount of available choice information for modeling the choices of individual decision...
