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...

This paper evaluates the effects of the lack of regulatory commitment on emission tax applied by the regulator, abatement effort made by the monopoly and social welfare comparing two alternative policy games. The first game assumes that the regulator commits to an ex-ante level of the emission...

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 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....

In this paper we argue that when a subgroup of countries cooperate on emission reduction, the optimal response of non-signatory countries reflects the interaction between three potentially opposing factors, the incentive to free-ride on the benefits of cooperation, the incentive to expand the...

China's rampant environmental pollution problems and rising greenhouse gas emissions and the resulting climate change are undermining its long-term economic growth. China, from its own perspective cannot afford to and, from an international perspective, is not meant to continue on the...

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....

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...

In this paper we analyze the relative importance and mutual behavior of two competing base-load electricity generation options that each are capable of contributing significantly to the abatement of global CO2 emissions: nuclear energy and coal-based power production complemented with CO2...
