This repository contains anonymised survey data, choice experiment material, and R code from a multilingual online survey of chocolate consumers in Switzerland conducted in June 2024. The survey was fielded in German, French, and Italian through Bilendi Schweiz AG within the Deliberative Diets research project at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL), funded by the Swiss National Science Foundation.

The survey included questions on chocolate purchasing behavior, attitudes and beliefs regarding ethically produced chocolate, socio-demographic characteristics, and a discrete choice experiment on chocolate tablet attributes. The choice experiment elicited preferences over product profiles varying by label, cocoa distribution channel, environmental impact of cocoa cultivation, place of chocolate production, and price premium.

The repository underlies three related studies based on the same empirical survey. The first is Towards an ethical chocolate supply chain: Matching Swiss consumer preferences with policy instruments, which uses the survey’s discrete choice experiment to derive a respondent-level behavioral proxy of ethical chocolate choice. The second study uses this proxy together with survey-based psychological constructs to analyse ethical consumption intentions, behavior, and policy support among Swiss chocolate consumers. The third study examines how Swiss consumers respond to disclosed supply-chain governance cues and how these preferences vary with latent psychological dispositions and feasibility constraints.

The archived materials are intended to support transparency and reproducibility. They include an anonymised master dataset, documentation of the choice experiment design, survey materials, and R scripts for preparing article-specific analytical datasets and reproducing the reported analyses.
