Notes

Conjoint table (irw_conjoint_2). Choice among a submarine canyon alternative, a cold-water coral alternative or neither ('nessuna', no attributes: opt-out, chosen in 3,264 of 7,200 sets), described by biodiversity, climate regulation, scientific value and price; the habitat label is the attr_habitat level. Attribute levels are the deposit's stored numbers (biodiversity 5/10/15, climate 0.5/1, scientific value 0/1, price 10-60), whose displayed wording and units are not in the deposit; fixed blocked design with 4 blocks of 9 sets. 800 respondents although the deposit description reports 544.

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