3,920 rated or chosen profiles from 280 respondents, in up to 7 tasks of 2 profiles varying on 6 attributes.

About this table

Description	Staff of six UN organizations (elite survey recruited by email and LinkedIn, n = 280) compared 7 pairs of hypothetical voluntary contributions varying earmarking (own area of work, country, sector, project), spending period and donor type; outcomes are a forced choice and, per contribution, the minimum worthwhile amount, the overhead to charge, and rejection.

Notes

Conjoint table (irw_conjoint). Paired contributions, 7 tasks; choice = forced choice between Contribution 1 and 2 (wording not reported, no opt-out); rating_amount = minimum worthwhile grant (million USD) and rating_overhead = overhead to charge (%), both open-text answers stored as the authors' numeric cleaning; rating_refuse = 1 if the respondent wrote 'No' (reject the contribution). Six binary features independently randomized; only respondents who completed all 7 pairs are in the deposit (280, as in the paper).

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

Outcomes:

choice	Forced choice between Contribution 1 and Contribution 2 (paraphrase; wording not reported) [choice, forced]
rating_amount	The typical contribution to a UN organization is approximately 1.84 million USD. For each of the two contributions, please indicate in million USD how large the minimum grant amount would need be to be worth it for the international organization (please write “No” if you do not think that the international organization should accept the contribution) (stored: authors' numeric cleaning of the open answer, million USD) [rating, 0 (0 million USD) to 970 (open answer (largest observed 970 million USD))]
rating_overhead	The typical overheads charged by a UN organization is around 11% (Baumann and Weinlich 2020). For each of the two contributions, please indicate how much overheads an international organization should charge in percent (please write “No” if you do not think that the international organization should accept the contribution) (stored: authors' numeric cleaning of the open answer, percent) [rating, 0 (0 percent) to 100 (100 percent)]
rating_refuse	Rejected the contribution (wrote “No” in the open answers) (paraphrase; authors' coding) [rating, 0 (accepted) to 1 (rejected)]
