We study the transition between non renewable and renewable energy sources with adjustment costs over the production capacity of renewable energy. Assuming constant variable marginal costs for both energy sources, convex adjustment costs and a more expensive renewable energy, we show the...

Inside a standard growth model with exhaustible resources, we study the optimal growth policy of an economy submitted to a climate constraint, taking the form of a ceiling over admissible atmospheric carbon concentrations. The optimal scenario is a three phases path: a rise of carbon...

Carbon capture and sequestration (CCS) can help to mitigate the climate change transition. Usually, in models where the atmospheric carbon stock is constrained by an institutional stabilization cap and under constant average CCS cost, the use of CCS must be delayed up to the time at which the...

We study in this report a model of optimal Carbon Capture and Storage in which the reservoir of sequestered carbon is leaky, and pollution eventually is released into the atmosphere. We formulate the social planner problem as an optimal control program and we describe the optimal consumption...

Using a standard Hotelling model of resource exploitation, we determine the optimal consumption paths of three energy resources: dirty coal, which is depletable and carbon-emitting; clean coal, which is also depletable but carbon-free thanks to an abatement technology (CCS: Carbon Capture and...

Two-period Cournot competition between n identical firms producing at constant marginal cost and able to store before selling has pure strategy Nash- perfect equilibria, in which some firms store to exert endogenously a leader- ship over rivals. The number of firms storing balances market share...

Using the Chakravorty et al. (2006) ceiling model, we characterize the optimal consumption paths of three energy resources: dirty oil, which is non-renewable and carbon emitting; clean oil, which is also non-renewable but carbon-free thanks to an abatement technology, and solar energy, which is...

Pollution accumulation may result in more or less severe losses of natural self-cleaning capacities. We study a polluting resource management problem submitted to a potential shift from a high to a low pollution self-regeneration regime be crossed some critical pollution stock threshold. We rst...
