Alexander von Kotzebue investigates the interdependency of charitable giving, fundraising, and governmental intervention. His study comprises a literature survey, a model of the donor-fundraiser relation, and finally, an econometric analysis of the impact of fundraising on giving behaviour. The survey introduces theoretical approaches to donor motivation, groups them according to their central assumptions, and assesses their empirical relevance. The theoretical analysis takes for granted that fundraising is an integral part of the giving process, and models the potential conflict concerning the amount of fundraising exerted. Fundraising typically displays an ambiguous effect on donor utility. The empirical analysis employs two extensive datasets to investigate this complex donor-fundraiser relation, while establishing a convincing link of donor-level data to non-profit financial data.
