Does online fundraising increase charitable giving? Using the Facebook advertising tool, we implemented a natural field experiment across Germany, randomly assigning almost 8,000 postal codes to Save the Children fundraising videos or to a pure control. We studied changes in the volume and frequency of donations to Save the Children and other charities by postal code. Our design circumvents many shortcomings inherent in studies based on click-through data, especially substitution and measurement issues. We found that (i) video fundraising increased donation frequency and value to Save the Children during the campaign and in the subsequent five weeks; (ii) the campaign was profitable for the fundraiser; and (iii) the effects were similar independent of video content and impression assignment strategy. However, we also found non-negligible crowding out of donations to other similar charities or projects. Finally, we demonstrated that click data are an inappropriate proxy for donations and recommend that managers use careful experimental designs that can plausibly evaluate the effects of advertising on relevant outcomes.... view less
