This article distinguishes criminal, legal, and ethical transplantation as three distinct concepts, with the goal of building a conceptual framework to enable innovation. We strongly believe that international efforts should concentrate on increasing the availability of ethical high-quality...

Problem definition: More than 25 million refugees lived in camps in 2019 due to multiple armed conflicts worldwide. Humanitarian organizations (HOs) help refugees through in-kind (e.g. food) assistance traditionally and, just recently, through cash (monetary assistance) that refugees can spend...

There are powerful fairness and efficiency arguments for making charitable donations to soup kitchens 100% deductible. These arguments have no purchase for donations to fund opulent church organs, yet these too are 100% deductible under the current tax code. And this stark dichotomy is only the...

Social media outlets provide nonprofit organizations the opportunity of opening new communication and disclosure channels. Organizations must decide whether to set up these channels. They—and in turn their target audiences—must also decide how much to use social media. In this study, we test...

We describe a dynamic model of costly information sharing, where private information affecting collective-value actions is transmitted by social proximity. Individuals make voluntary contributions towards the provision of a pure public good, and information transmission about quality of...

We present evidence from a natural field experiment and structural model designed to shed light on the efficacy of alternative fundraising schemes. In conjunction with the Bavarian State Opera, we mailed 25,000 opera attendees a letter describing a charitable fundraising project organized by the...

In a door-to-door fundraising field experiment, we study the impact of fundraising mechanisms on charitable giving. We approached about 4500 households, each participating in either an all-pay auction, a lottery, a non-anonymous voluntary contribution mechanism (VCM), or an anonymous VCM. In...

This paper examines the impact of payment choice on charitablegiving with a door-to-door fund-raising field experiment. Respondentscan donate cash only, use debit only, or have both options. Cash donations have lower visibility vis-a-vis solicitors than debit card donations. When debit replaces...

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...
