This paper studies how sulfur protocols trigger invention and diffusion of technologies for reducing SO2 emissions. For this goal we constructed a patent data set on SO2 abatement technologies filed in 15 signatory and non-signatory countries in the period 1970-1997. Our data enable us to study...

This paper studies patenting decisions by firms in relation to the negotiation and signing of the Helsinki and Oslo protocol as part of the Convention on Long-Range Transboundary Air Pollution. We use a uniquely constructed patent data set on SO2 abatement technologies filed in 15 signatory and...

Multi-pollutant interactions can have crucial implications for the design and performance of environmental policy targeting single pollutants. This paper presents a two-region model where a global pollutant (CO2) and local pollutant (SO2) are produced jointly. The interaction between SO2 and CO2...
