We examine the relationship between competition and innovation in an industry where production is polluting and R&D has the aim to reduce emissions (“green” innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in “green” R&D. We analyse the case where the emission tax is set endogenously by a committed regulator and uncover an inverted-U relationship between innovation and competition that is mainly driven by the presence of R&D spillovers.
