The paper examines the relevant cost benefit framework for public authorities investigating the potential of local projects to mitigate climate change. Because these projects are typically limited in time and space, continuation pathways need be introduced to capture the benefits provided by a...

The transition of a sector from a pollutant state to a clean one is studied. A green technology, subject to learning-by-doing, progressively replaces an old one. The notion of abatement cost in this dynamic context is fully characterized. The theoretical, dynamic optimization, perspective is...

We assume that a project requires an initial outlay and may either succeed or fail. The probability of success depends on its type and on the effort of the firm. Only in the case of success do private and external benefits appear. The paper analyzes the optimal design of subsidies under...

Two-player infinitely-repeated-entry games are revisited using a new Markov equilibrium concept. The idea is to have an incumbent facing a hit and run entrant. Rent dissipation no longer necessarily holds. It will not when competition is tough in case of entry. Similarities and differences with...
