The optimal transition to a low-carbon economy must account for adjustment costs in switching from dirty to clean capital, technological progress, and economic and climatic shocks. We study the low-carbon transition using a dynamic stochastic general equilibrium model with emissions abatement...

To mitigate climate change, some governments opt for instruments focused on investment, like performance standards or feebates, instead of carbon prices. We compare these policies in a Ramsey model with clean and polluting capital, irreversible investment and a climate constraint. Alternative...

Different countries of the world are affected differently by the adverse impacts of anthropogenic climate change. For a large country consisting of several regions with different geographical conditions, the direct geographical impacts of climate change may differ significantly. Given the...

This paper introduces geoengineering into an optimal control model of climate change economics. Together with mitigation and adaptation, carbon and solar geoengineering span the universe of possible climate policies. Their wildly different characteristics have important implications for climate...

This policy note analyses the impacts of climate change on a small and open economy, emphasizing its effect on monetary policy. We use a New-Keynesian model to evaluate short- and long-term effects of transition climate change shocks - a permanent and anticipated shock to total factor...

This paper introduces geoengineering into an optimal control model of climate change economics. Together with mitigation and adaptation, carbon and solar geoengineering span the universe of possible climate policies. Their wildly different characteristics have important implications for climate...

This paper describes an integrated assessment model with an unknown temperature threshold where severe and irreversible climate impacts, called a tipping point, occurs. The possibility of tipping leads to the following linked outcomes: a prolonged period of peak temperature; a rebound in...

Most people are convinced that climate change is a threat and that it should somehow be dealt with. It is also clear that CO2 emissions are still too cheap and must be priced higher to sufficiently curtail emissions. Yet how high should a carbon tax be? Answering this question requires...

This paper introduces geoengineering into an optimal control model of climate change economics. Together with mitigation and adaptation, carbon and solar geoengineering span the universe of possible climate policies. We show in the context of our model that: (i) a carbon tax is the optimal...

We study clean energy production subsidies in a quantitative climate-economy model. Clean energy production subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient production subsidy equals the marginal external cost of dirty...
