Technological development is likely to play an important role in curbing growth in greenhouse gas emissions. It is therefore important to incorporate factors influencing technological change in climate policy analyses. This paper studies climate policy when there are technology spillovers...

We study an international climate agreement that assigns emission quotas to each participating country. Unlike the simplest models in the literature, we assume that abatement costs are affected by R&D activities undertaken in all firms in all countries, i.e. abatement technologies are...

We study climate policy when there are technology spillovers within and across countries, and the technology externalities within each country are corrected through a domestic subsidy of R&D investments. We compare the properties of international climate agreements when the inter-country...

With limited participation in an international climate agreement, standard economic analysis suggests that a unilateral action taken by a group of countries in order to reduce its emissions is likely to be undermined by increases in emissions from other countries (carbon leakage). While analyses...

We study second-best climate agreements in the presence of technology spillovers within and across countries, where the technology externalities within each country are corrected through a domestic subsidy of R&D investments. We compare the properties of two types of international climate...
