Choosing vs. allocating: discrete choice experiments and constant-sum paired comparisons for the elicitation of societal preferences.

The article presents a study which aims to compare discrete choice experiment (DCE) and constant- sum paired comparison (CSPC) methods for eliciting societal preferences. The researchers detail the methodology and procedures in data gathering to compare outcomes. It implies that CSPC may offer advantages over DCE in eliciting societal preferences over the distribution of resources and/or outcomes.
