Financial Conditions and Green Innovation
CEPR
2026.09.10
This paper studies how financial conditions affect research and development (R&D) by firms specialized in green innovation. Using U.S. patent data matched with Compustat, we identify “green innovators” as firms with a high cumulative share of green patents. Although they account for a small share of total green patenting, these firms occupy central positions in the green-innovation ecosystem. Estimating firm-level impulse responses to exogenous changes in broad financial conditions, we find that tightening has a disproportionately large and persistent negative effect on the R&D of specialized green innovators. In contrast, R&D by diversified innovators and non-innovators responds only weakly. Green innovators are younger, smaller, and more dependent on external finance, suggesting that financial tightening introduces a systematic bias against upstream green technological development.
