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...

This paper is a single-project meta-analysis of four experiments that first model charitable giving as individual contributions to a multiplicity of competing threshold public goods. Given the centrality of the coordination dilemma as the number of recipients increases, we pool 15,936...

As a dynamic way to raise funds for professional and private projects in recent years, crowdfunding has made tremendous progress, especially through online platforms. However, research on this subject is still young, leaving room for different perspectives. We therefore approach the marketing...

Ineffective fundraising lowers the resources charities can use for goods provision. We combine a field experiment and a causal machine-learning approach to increase a charity's fundraising effectiveness. The approach optimally targets fundraising to individuals whose expected donations exceed...

Experimental studies have modeled individual funding of social projects as contributions to a threshold public good. We examine donors' behavior when they face multiple threshold public goods and the possibility of coordinating their contributions via an intermediary. Employing the experimental...

Kleine und mittlere Unternehmen (KMU) sind ein zentrales Rückgrat nationaler Wirtschaftssysteme. Die Forschung zeigt, dass KMU aufgrund ihrer geringeren Größe nicht nur vergleichsweise weniger formalisierte, weniger komplexe und weniger spezialisierte Organisationsstrukturen haben, sondern...

This paper characterizes efficient tax subsidies for charitable contributions, and considers the properties of potential reforms. Contributions are underprovided in the absence of subsidies, and are misdirected if subsidies fail to account for all of the costs that donors incur. It is costly for...

We conducted a field experiment in the natural setting of blood donations to test how oxytocin relates to empathy and altruism. We randomly assigned blood donors in the Croatian Institute for Transfusion Medicine to three groups with the aim to induce different levels of empathy by showing a...

We conducted two fundraising experiments to study the effects (1) of compassion towards the beneficiary, and (2) of giving participants an opportunity to attribute small donations to luck. We find that exposing the participants to a plea to help the beneficiary increases the average donation....

Does online fundraising increase charitable giving? We implemented a natural field experiment across Germany, randomly assigning all of the country's 8,000 zip codes to Save the Children Facebook fundraising videos or a pure control and studied changes in the volume of donations to this and...

In an artefactual field experiment, we implemented a crowdfunding campaign for an institute's summer party and compared donation and contribution framings. We found that the use of the word 'donation' generated higher revenue than the use of 'contribution'. While the individuals receiving the...

We investigate whether the presence of a default interacts with the willingness of decision-makers to gather, process and consider information. In an online experiment, where about 2,300 participants choose between two compiled charity donation options worth $100, we vary the availability of...

How does a citizen's decision to participate in political activism depend on the participation of others? We conduct a nation-wide natural field experiment in collaboration with a major European party during a recent national election. In a party survey, we randomly provide canvassers with true...

We provide novel evidence on the linkages between capital taxation and charitable giving on three fronts. First, we use quasi-experimental variation in the annual Norwegian wealth tax to study the effect on how much households give. Inconsistent with the notion that households give more in order...

Does social recognition motivate prosocial individuals? We run large-scale experiments among members of Italy's main blood donors association, testing social recognition both through social media and peer groups. We experimentally disentangle visibility concerns and peer comparisons, and we...

Has the COVID-19 pandemic affected pro-sociality among individuals? After the onset of the pandemic, many charitable appeals were updated to include a reference to COVID-19. Did donors increase their giving in response to such changes? In order to answer these questions, we conducted a...

Why do people give when asked, but prefer not to be asked, and even take when possible? We introduce a novel analytical framework that allows us to express context dependence and narrow bracketing axiomatically. We then derive the utility representation of distributive preferences additionally...

In an artefactual field experiment, we implemented a crowdfunding campaign for an institute's summer party and compared donation and contribution framings. We found that the use of the word 'donation' generated higher revenue than the use of 'contribution'. While the individuals receiving the...

We study a form of threshold matching in fundraising where donations above a certain threshold are topped up with a fixed amount. We show theoretically that threshold matching can induce crowding in if appropriately personalized. In a field experiment, we explore how thresholds should be chosen...

I investigated how people's childhood experiences of involvement in team sports helped them develop non-cognitive skills, which later prompted them to make charitable donations to disaster victims. I independently collected individual-level data from approximately 7000 observations in 2016. The...
