29,990 rated or chosen profiles from 2,999 respondents, in up to 5 tasks of 2 profiles varying on 6 attributes.

| Description | Adults in Poland (bilendi online panel, 2022; n = 2,999) chose between and rated (1-7) 5 pairs of hypothetical trade agreements varying in yearly gains or losses (zloty (5 x the euro value)) for themselves, the average citizen and the average citizen of the partner country, plus partner size, current trade volume and implementation year. |

| Randomization restrictions | yes (stated by the source): No agreement with losses on all three payoff attributes (personal, citizen, foreign; 1.45% of payoff combinations); a profile was redrawn if it matched the other profile on all three payoffs. Payoff values drawn in steps of 10 from -100 to 300 (euro; x5 in zloty in Poland). |
| Task order | recorded in the deposit |
| Profile position | recorded in the deposit |
Because the attribute levels were not randomized independently, an estimator has to account for the restriction; a plain difference in means across levels can mislead.
Outcomes:
| choice | Which of the two trade agreements do you prefer? (paraphrase; the article: respondents were asked 'to choose between and to rate (on a scale from 1 to 7) two hypothetical trade agreements') [choice, forced] |
|---|---|
| rating | Rating of each agreement on a scale from 1 to 7 (paraphrase; article Sec. 4.1) [rating, 1 (muy en contra) to 7 (muy a favor)] |
