Abstract: |
We examine the relationship between competition and innovation in an industry
where production is polluting and R&D aims to reduce emissions ("green"
innovation). We present an n-firm oligopoly where firms compete in quantities
and decide their investment in "green" R&D. When environmental taxation is
exogenous, aggregate R&D investment always increases with the number of firms
in the industry. Next we analyse the case where the emission tax is set
endogenously by a regulator (committed or time-consistent) with the aim to
maximise social welfare. We show that an inverted-U relationship exists
between aggregate R&D and industry size under reasonable conditions, and is
driven by the presence of R&D spillovers. |
