We experimentally test a theoretically promising amendment to the ratchet-up mechanism of the Paris Agreement. The ratchet-up mechanism prescribes that parties’ commitments to the global response to climate change cannot decrease over time and our results confirm that its effect is...

We estimate the tax price elasticity of charitable giving using newly-available data from the Panel Study of Income Dynamics spanning 2001-2017. We find that households that always itemize are less sensitive to changes in the tax treatment of donations than house-holds that switch itemizing...

We provide evidence that individuals substitute between political contributions and charitable contributions, using micro data from the American Red Cross and Federal Election Commission. First, in a lab experiment, we show that information on the importance of charitable giving increases...

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...

I experimentally investigate whether there is a gender difference in advice giving in a gender-neutral task with varying difficulty in which the incentives of the advisor and the decision maker are perfectly aligned. I find that women are more reluctant to give advice compared to men for...

I draw on new data to examine how donor-advised funds (DAFs), a fast-growing philanthropic option, relate to social progress. DAFs are distinguished by flexibility -- transforming complex assets and separating the timing of tax breaks from giving decisions. While DAFs are often classified by...

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...
