Everything changes: A look at sustainable investing and disclosure over time and a discussion of “Institutional investors, climate disclosure, and carbon emissions”

This paper summarizes and discusses Cohen et al. (2023), including how their results fit into a larger set of open questions about how sustainability-oriented information gets used in capital markets. Two key messages emerge. The first is that investors are not a monolith. The second message is that the information environment in which investors have been operating has changed dramatically over the past two decades and is likely to continue to evolve for the foreseeable future. Both messages have important implications for researchers when thinking about how to design empirical tests of theoretical relationships.
