Ross YR 2021 UL http://le.uwpress.org/content/early/2021/08/27/wple.97.3.080319-0111R1.abstract AB Through a randomized, controlled laboratory experiment and a natural field experiment with a non-profit organization partner, we test the efficacy of economic valuation information as a communication strategy for encouraging environmental philanthropy. While the use of monetary values in fundraising appeals might encourage some to give, for others it may crowd out intrinsic motivation to donate. We find that recent monetary support of environmental causes and organization membership status interact with the economic valuation treatment. Significant heterogenous effects are found in both experiments, but evidence of motivation crowding is found only in the field.
