Notes

Conjoint table (irw_conjoint_2). Choice between two forest-landscape alternatives and a status quo ('neither', option 3, stored without attribute levels, so opt_out = yes) in 8 sets per respondent, Slovakia sample; attributes are forest management share (0%, 20%, 40% and 70%), access, guided tours and fee (10-100, currency not stated). Level wording is taken from the authors' Apollo script parameter names because the deposit has no codebook, so the meaning of the share and the fee currency are unknown. Task is the design set index (presentation order not documented).

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