Land use change and land management intensification are major drivers of biodiversity loss, especially in agricultural landscapes, that cover a large and increasing share of the world's surface. Incentive-based agrienvironmental policies are designed to influence farmers' land-use decisions in...

European forests are a resource that is targeted by several EU environmental and land use policies as forests can be of critical importance to mitigate climate change. At the same time, they are central to the EU's biodiversity policy, and particular the Natura 2000 network of protected areas....

We determine the optimal exploitation time-paths of two energy resources, one being depletable and polluting, namely a fossil fuel, the other being renewable and clean. These optimal paths are considered along with the two following features. First, the cumulative atmospheric pollution stock is...

The paper investigates a climate-economy model with an iso-elastic welfare function in which one parameter gamma measures relative risk-aversion and a distinct parameter rho measures resistance to intertemporal substitution. We show both theoretically and numerically that climate policy responds...

Taking climate change as an example, this paper provides new insights on the optimal provision of a long-term public good within and across generations. We write the Bowen–Lindhal–Samuelson (BLS) conditions for the optimal provision of the public good in a world divided into N...

Stimulating renewable energy is a crucial objective in view of tackling climate change and coping with future fossil fuel scarcity. In France, fuelwood appears to be an important source for the renewable energy mix. Using the French Forest Sector Model, our paper aims to assess the impacts of...

In this paper the author discusses the fact that economists define optimal IP rights as a continuum of options in three dimensions: height, breadth and length. At the operational level he discusses the impossibility of multiplying rights indefinitely (due to prohibitive transaction costs), as...

Dans cet article, les auteurs s’appuient sur le modèle du ménage producteur pour analyser la formation et les inégalités du revenu des ménages d’agriculteurs en utilisant un raccordement réalisé par l'Insee entre le Réseau d'information comptable agricole (Rica) et des données...
