Oxytocin, empathy, altruism and charitable giving : experimental evidence from blood donations
Jukić, Irena; Kovač, Dejan; Vuletić Čugalj, Danijela - Leibniz-Institut für Wirtschaftsforschung Halle - 2023
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 … induced levels of oxytocin. Null effects of our treatments could be explained by the above average baseline levels of oxytocin …

Blood donations and incentives : evidence from a field experiment
Götte, Lorenz; Stutzer, Alois - 2019
There is a longstanding concern that material rewards might undermine pro-social motivations, thereby leading to a decrease in blood donations. This paper provides an empirical test of how material rewards affect blood donations in a three-month large-scale field experiment and a fifteen-month...

The shape of warm glow : field experimental evidence from a fundraiser
Carpenter, Jeffrey P. - 2018
Theory commonly posits agents who care both for the level of provision of a public good and the extent to which they personally contribute to the cause. Simply put, agents feel some "warm glow" from the donations they make. I discuss a fundraiser devised to exogenously vary the incentive to give...

Incentives and the design of charitable fundraisers : lessons from a field experiment
Carpenter, Jeffrey P.; Matthews, Peter Hans - 2015
There has been little systematic study of the mechanisms typically used to raise money for charity. One of the most common is the simple raffle in which participants purchase chances to win a prize at a constant price. We conduct a field experiment randomly assigning participants to four raffle...

Choosing your object of benevolence: a field experiment on donation options
Aretz, Bodo; Kube, Sebastian - 2010
In a large natural field experiment, we explore the effect of providing donors with the opportunity to choose the target country for their donations. We find that only a small fraction of donors use the option, which might reflect a reluctance to consider tradeoffs when those concern important,...

'Feel the Warmth' Glow : A Field Experiment on Manipulating the Act of Giving
Chuan, Amanda - 2013
We conducted a field experiment with a charitable group to investigate whether giving the donor an option to write a personal message to the recipient influences giving behavior. Over 1,500 households were approached in a door-to-door campaign and randomized to either a control or a treatment in...

Giving Once, Giving Twice : A Two-Period Field Experiment on Narrow Framing in Charitable Giving
Adena, Maja - 2017
Do donors examine a single ask to donate in isolation or do they consider that other and future asks may come along? In the first year of our field experiment, we vary whether or not potential donors are informed that the ask will be repeated in the following year. This information has dramatic...

Personalized fundraising : a field experiment on threshold matching of donations
Adena, Maja; Huck, Steffen - 2022
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...

Subsidizing unit donations : matches, rebates, and discounts compared
Diederich, Johannes; Eckel, Catherine C.; Epperson, Raphael - 2020 - This version: October 7, 2020
An influential result in the literature on charitable giving is that matching subsidies dominate rebate subsidies in raising funds. We investigate whether this result extends to 'unit donation' schemes, a popular alternative form of soliciting donations. There, the donors' choices are about the...
