*Authors* Philipp Schoenegger, Kian Mintz-Woo https://doi.org/10.1016/j.jenvp.2024.102288 *03 April 2024* *Highlights* •Informs an important policy issue: dissemination of information about solar radiation management, a geoengineering option. •Adopts best practices: includes salience control and content control conditions in a large-scale, well-powered experiment. •Tests both stated preferences and behavioural choices. •Finds no statistically significant effect for moral hazard. •Uses TOST to find evidence for a null effect. *Abstract* Solar radiation management (SRM) may help to reduce the negative outcomes of climate change by minimising or reversing global warming. However, many express the worry that SRM may pose a moral hazard, i.e., that information about SRM may lead to a reduction in climate change mitigation efforts. In this paper, we report a large-scale preregistered, money-incentivised, online experiment with a representative US sample (N = 2284). We compare actual behaviour (donations to climate change charities and clicks on climate change petition links) as well as stated preferences (support for a carbon tax and self-reported intentions to reduce emissions) between participants who receive information about SRM with two control groups (a salience control that includes information about climate change generally and a content control that includes information about a different topic). Behavioural choices are made with an earned real-money endowment, and stated preference responses are incentivised via the Bayesian Truth Serum. We fail to find a significant impact of receiving information about SRM and, based on equivalence tests, we provide evidence in favour of the absence of a meaningfully large effect. Our results thus provide evidence for the claim that there is no detectable moral hazard with respect to SRM. *Source: ScienceDirect * -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
