Explaining monetary donations to international development organisations: A factorial survey approach

•Organisational characteristics influence giving intentions of (potential) donors.•Overhead costs negatively influence giving intentions of (potential) donors.•(Potential) donors are in favour of experienced, familiar organisations.•To donors high in social trust the familiarity of an organisation remains important.•The ideal organisation is a hybrid, rarer type of organisation.

This article investigates what type of international development organisations potential donors would prefer to donate to. We constructed 960 scenarios in which a fictive development organisation was described. The scenarios were randomly varied across eight characteristics of the organisation: size, familiarity, experience, religious character, number of different projects run by the organisation, number of countries in which the organisation is active, overhead costs and staff composition. A large representative sample of the Dutch population (N = 2,758) received six randomly allocated scenarios and had to decide if, and if so, how much they would donate to the depicted (fictive) organisation. Results demonstrate that donors have a preference for familiar organisations with several years of experience. Although donors have a strong aversion regarding overhead costs, we find that donors seem to value the capacities of paid staff members and are, to a certain extent, willing to pay a price for these. The ideal development organisation combines features typical of small(er) scale voluntary development organisations (e.g. mainly run by volunteers) and large(r) scale professional organisations (e.g. running development programmes in numerous countries).
