This paper presents an examination of the socially efficient formation of environmental R&D in Cournot duopoly in a setting where a regulator has no precommitment ability for an emission tax. The results reveal that if the environmental damage is slight, alternatively, given severe environmental...

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....

This paper provides a review of the literature on competitiveness and leakage concerns associated with differentiated climate abatement commitments among countries. The literature reviewed is not exhausted, but it is sufficient to provide a balanced view of both academics and policy circles....

International carbon offsets have been promoted since the Kyoto Protocol and an increasing number of countries have implemented or proposed cap-and-trade schemes with international trading, even though with quantitative or qualitative restrictions. Those limits reflect the trade-off between...

We analyze the quantitative labor market and aggregate effects of a carbon tax in a framework with pollution externalities and equilibrium unemployment. Our model incorporates endogenous labor force participation and two margins of adjustment influenced by carbon taxes: firm creation and green...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between 'dirty' (internal combustion engine) and 'clean' (e.g. electric and hybrid) patents across 80 countries over several decades. We show that...
