RT Journal Article SR Electronic T1 Economic Valuation as a Communication Device for Environmental Philanthropy: Evidence from the Lab and Field JF Land Economics JO Land Econ FD University of Wisconsin Press SP 588 OP 607 DO 10.3368/le.97.3.588 VO 97 IS 3 A1 Goff, Sandra H. A1 Noblet, Caroline L. A1 Anthony, J. Ross YR 2021 UL http://le.uwpress.org/content/97/3/588.abstract AB Through a randomized, controlled laboratory experiment and a natural field experiment with a nonprofit organization partner, we test the efficacy of economic valuation information as a communication strategy for encouraging environmental philanthropy. Although 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 heterogeneous effects are found in both experiments, but evidence of motivation crowding is found only in the field.
