This paper investigates the relationship between measures of environmental performance and of social preferences, thanks to the availability of a recently published dataset on global pref- erences. Using cross-sectional observations from 76 countries, this study finds evidence from macro data of a positive and statistically significant relationship between measures of proso- cial preferences, such as positive reciprocity, trust, and altruism, and environmental policy indicators in the categories of agriculture, forestry, and climate change after controlling for economic and geospatial factors. At the micro level, the results presented in this paper suggest a broader theory of collective action that is based on a behavioral approach to climate policy to mitigate motivational crowd out in settings of high reciprocity and trust. At the macro level, the results presented in this paper suggest a broader theory of climate clubs that includes pro- social preferences, such as positive reciprocity, trust, and altruism, as key cooperation mech- anisms in International Environmental Agreements.
