Notes

Conjoint table (irw_conjoint_2). Choice among three labelled products (organic, conventional or circular farming, each with a price in EUR per 500 g, 1 liter or 450 g) or 'None of these', in four purchase situations for each of pork, milk and sliced bread the respondent buys (tasks 1-12 in survey order; trial_product says which). 'None of these' has no levels, so it is the opt-out and has no row. Fixed design with the same prices for every respondent; Belgium, Croatia, Hungary, Italy, Poland and Spain are pooled. The open-ended quantity block is dropped. Source article not identified.

These notes describe the source data, which the IRW reproduces as released. All notes are listed on the Data Notes page.
