The salience of future impacts and the willingness to pay for climate change mitigation: an experiment in intergenerational framing

Abstract

Globally, investment in climate change mitigation has lagged far behind the optimal level as estimated by a large body of science. This lag may be caused, in part, by the psychological distance between decision-makers today and those who will likely experience the worst impacts of climate change in the future. This psychological distance reduces the salience of those impacts in today’s decisions. In a randomized control experiment using a letter-to-the-future treatment and a climate change essay treatment, I find that compared to a control group, both writing tasks that focus attention on the future risks of climate change increase the willingness to donate to climate change mitigation efforts. I also find evidence that for parents and grandparents, writing a letter to one’s child or grandchild increases the salience of existing concerns about how climate change may impact one’s children. These findings contribute to the understanding of how to bridge the psychological distance between choices and consequences for climate change mitigation and have implications for a wide range of decisions from personal health choices to retirement savings.
