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...

The effective labor possibilities frontier (ELPF) is defined as the set of statically efficient allocations of labor inputs in the competing tasks of production and R&D. It is concave if labor is heterogeneous. In an R&D-based growth model with an essential non-renewable natural resource, the...

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...

We determine the optimal exploitation time-paths of three types of perfect substitute energy resources: The first one is depletable and carbon-emitting (dirty coal), the second one is also depletable but carbon-free thanks to a carbon capture and storage (CCS) process (clean coal) and the last...

We characterize the optimal exploitation paths of two perfect substitute primary energy resources, a non-renewable polluting resource and a carbon-free renewable one. Both resources can supply the energy needs of two sectors. Sector 1 is able to reduce its carbon footprint at a reasonable cost...
