We study optimal pollution abatement under a mixed oligopoly game when firms engage in emissions-reducing R&D that is imperfectly appropriable. The regulator uses a tax to curb emissions. Results show that in a mixed oligopoly, the public firm has positive emissions reduction in equilibrium;...

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 consider a model of horizontal product differentiation between two firms where locations are identified with eco-quality. The duopolists face spillover effects and locations are determined endogenously through R&D investments. We examine the resulting equilibrium locations when consumers...

Politicians and international organisations advocate for increased regulation and government control of industry in order to handle climate change and reduce overall greenhouse gas emissions. However, it remains an open question how economic freedom is associated with environmental damage and...

It is widely accepted that one of the most important characteristics of an effective pollution control policy is to provide firms with credible incentives to make long-run investments in R&D that can drastically reduce pollution. Recognizing that a government may be tempted to revise its policy...

Many countries have pledged targets or actions to reduce greenhouse gas emissions; these have been listed in the Appendices to the Copenhagen Accord and, at the time of writing, are being transferred to the UNFCCC Cancún Agreements. This analysis examines the costs and effectiveness of these...

We take a decentralized approach to regulating environmental pollution in settings where each agent's pollution possibly affects all others. There is no central agency to enforce pollution abatement or coordinate monetary transfers. Moreover, agents possess private information, which precludes...

China is appraised to have the world's largest exploitable reserves of shale gas, although several legal, regulatory, environmental and investment-related issues will likely restrain its scope. China's capacity to successfully face these hurdles and produce commercial shale gas will have a...
