Abstract

This article evaluates if and to which extent policy can steer innovation towards eco-friendly technologies. We construct a cross-country dataset on sectoral green innovation and complement it with data on policies designed to address environmental market failures: environmental taxes, regulation, and R&D subsidies. While all of these tools exert a positive effect on green innovation, our IV estimates reveal substantial heterogeneities across policies. Overall, green innovation reacts most strongly to R&D subsidies for renewables, but interaction effects between different policies need to be considered.
