In a large-scale natural field experiment, we partnered with a micro-lending company in Kyrgyzstan that asked over 180,000 of its clients for donations to social projects as a form of corporate philanthropy. In a 2x2 design, we explored two main (pre-registered) hypotheses about giving by the...

We study intertemporal crowding between two fundraising campaigns for the same charitable organization by manipulating donors’ beliefs about the likelihood of future campaigns in two subsequent field experiments. The data shows that initial giving is decreasing in the likelihood of a future...

We study a form of threshold matching 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 depending on...

Previous studies of charitable giving have focused on middle- or high-income earners in Western countries, neglecting the poor, although the lowest income groups are often shown to contribute substantial shares of their income to charitable causes. In a large-scale natural field experiment with...

Some companies engage in mass fundraising in addition to their core business. Via a corporate social responsibility (CSR) channel this may increase sales. However, ask avoidance, if present, could imply that fundraising activities may harm a company's core business. We examine how asking for...

We study intertemporal crowding between two fundraising campaigns for the same charitable organization by manipulating donors' beliefs about the likelihood of future campaigns in two subsequent field experiments. Theory predicts that the effect of such belief manipulations depends on whether...
