Carbon capture and storage (CCS) seems an appealing option to meet the ambitious objectives of the Paris Agreement. Captured CO2 emissions can also be injected in active fields to enhance recovery: Carbon capture and utilization (CCU). We study a dynamic model of CCS and CCU of an economy...

Optimal climate policy is studied in a Ramsey growth model. A developing economy weighs global warming less, hence is more likely to exhaust fossil fuel and exacerbate global warming. The optimal carbon tax is higher for a developed economy. We analyze the optimal time of transition from fossil...

We consider a game between oligopolistic and fringe suppliers of fossil fuel from an exhaustible resource, and of producers of a renewable perfect substitute. Extraction costs are stock-dependent and strictly convex in the rate of extraction. We characterize the open-loop equilibrium...
