We consider a general equilibrium climate change model with two endogenous R&Dsectors. First, we characterize the set of decentralized equilibria : to each vector of publictools ? a carbon tax and a subsidy to each R&D sector ? is associated a particularequilibrium. Second, we compute the...

The paper considers an endogenous growth model with climate change as well as three R&D sectors dedicated to energy, CCS (Carbon Capture and Storage) and backstop efficiency. First, we characterize the set of decentralized equilibria: a particular equilibrium is associated with any vector of...
