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...

This paper deals with the so-called 'double-dividend' of an environmental tax reform. We find that, in a model with only labor and a polluting input as factors of production, society faces a trade-off between internalizing environmental externalities and raising revenues in the least...

We incorporate the process of policy diffusion (i.e. the uncoordinated dissemination of policies among countries) into a probabilistic two-country-model of strategic environmental policy. Contrary to the usual setting with simultaneous decision making we consider the impact of sequential...

We examine the impact of an optimal emissions tax on research and development of emission reducing green technology (E-R&D) in the presence of R&D spillovers. We show that the size and effectiveness of the optimal emissions tax depends on the type of the R&D spillover: input or output spillover....
