We modify the vertically differentiated duopoly model by André et al. (2009) replacing Bertrand with Cournot behaviour, and we characterise the region wherein a Porter-type result takes place. We show that the Porter hypothesis applies in an equilibrium taking always the form of a prisoner's...

This paper examines whether stringent environmental regulations induce more R&D and promote further productivity in Taiwan. Using an industry-level panel dataset for the 1997–2003 period, empirical results show that pollution abatement fees, a proxy for environmental regulations, is positively...

Within a non-cooperative transboundary pollution game, we investigate the impact of the adoption of a cleaner technology (i.e., a decrease in the emission to output ratio). We show that countries may respond by increasing their emissions resulting in an increase in the stock of pollution that...

We model a market with environmentally conscious consumers and a duopoly in which firms consider the adoption of a clean technology. We show that as pollution increases, consumers shift more resources to the environmental activities, thereby affecting negatively the demand faced by the duopoly....

This paper examines the impact of participation in the Climate Wise program, one of the largest voluntary programs enacted in the US, on innovative activity by firms. In operation from 1993 to 2000, the Climate Wise program was designed to reduce greenhouse gas emissions by promoting innovation...

We analyze the effects of an environmental policy on the diffusion of a clean technology. Compared to previous articles we consider that the polluting firms are competitors on the output market and we analyze the effects of the policy on the share of adopting firms in the economy. We show that...

This paper is the first to examine the public economics of export-based externalities arising within the provisioning of ecosystem services, with direct application to policies to prevent the spread of hitchhiking invasive species. We find when risk enters through exports, policy makers face a...

Bio-energy with carbon capture and sequestration (BECCS) has the potential to be a key mitigation option, because it can generate electricity and absorb emissions at the same time. However, biomass is not distributed evenly across the globe and regions with a potentially high demand might be...

One country or sector that tries to reduce greenhouse gas emissions may fear that other countries or sectors will get a competitive advantage and increase emissions. Computable general equilibrium (CGE) models such as Elliott et al. (2010a, 2010b) indicate that 15–25% of abatement might be...

We investigate the performance of a consumption-based carbon tax – implemented by full border carbon adjustment – as an instrument of unilateral climate damage mitigation in a two-period two-country general equilibrium model with a finite stock of fossil fuel. The implementation of that tax...
