Notes

Conjoint table (irw_conjoint_2). Five tasks of two hypothetical countries (6 binary institutional attributes plus relative citizen income) in seven countries; choice of one country and a 0-10 rating of each (rating higher = liked more, 567 NA); no opt-out. Levels are the UK English text for the translations respondents saw in their own language (authors' recode reproduced); income stored as relative level with the displayed amount in trial_income_shown; no covariates or weights in the deposit.

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