INTERNATIONAL CLIMATE AGREEMENTS UNDER INDUCED TECHNOLOGICAL CHANGE

We examine the impact of technological change on the stability of climate coalitions and explore how international cooperation on abatement affects the incentives of signatories to invest in R&D to reduce emissions. We compare the case of no technological change with exogenous technological change and induced technological change. In the latter case R&D investments are endogenous. We find that the highest equilibrium pay-offs are achieved in the case of induced technological change. Furthermore, the formation of a climate coalition boosts R&D investments in carbon abatement technologies in signatory countries.
