This paper investigates the optimal timing of greenhouse gas abatement e orts in a multi-sectoral model with economic inertia, each sector having a limited abatement potential. It defines economic inertia as the conjunction of technical inertia - a social planner chooses investment on persistent...

This paper investigates the optimal timing of greenhouse gas abatement efforts in a multi-sectoral model with economic inertia, each sector having a limited abatement potential. It defines economic inertia as the conjunction of technical inertia --- a social planner chooses investment on...

Climate mitigation is largely done through investments in low-carbon capital that will have long-lasting effects on emissions. In a model that represents explicitly low-carbon capital accumulation, optimal marginal investment costs differ across sectors. They are equal to the value of avoided...

We analyze the impact of the private label production channel on innovation. A retailer may either choose a competitive fringe or rely on a brand manufacturer to produce its private label. The trade-o between the two channels is a choice between too much or too little innovation, i.e. quality...

This article analyzes the trade-off between yield and farmed area when a valuable species is affected by agricultural practices. Itrevisits, from an economic perspective, the ``land-sparing versus land-sharing'' debate elaborated in conservation biology using themethodology of the density-yield...

We analyze the impact of the private label production channel on innovation. A retailer may either choose to integrate backward with a small firm (insourcing) or rely on a national brand manufacturer (outsourcing) to produce its private label. The trade-off between insourcing and outsourcing...

In industries with large sunk costs, the investment strategy of firms depends on the regulatory context. We consider ex-ante industrial policies in which the sunk cost may be either taxed or subsidized, and antitrust policies which could either be pro-competitive (leading to divestiture in case...

Competitiveness and carbon leakage are major concerns for the design of CO2 emissions permits markets. In absence of a global carbon tax and of border carbon adjustments, output based allocation is a third best solution and is actually implemented (Australia, California, New Zealand). The EU has...

In this paper we analyze the effects of an environmental policy on the diffusion of a clean technology in an economy where firms compete on the output market. We show that the share of adopting firms is non-monotonic with the stringency of the environmental policy, and that the adoption of the...
