We develop a new methodology to estimate the elasticity of urban costs with respect to city population using French land price data. Our preferred estimate, which handles a number of estimation concerns, stands at 0.041. Our approach also yields a number of intermediate outputs of independent...

We build a benchmark framework to study optimal land use, encompassing land use activities and environmental degradation. We focus on the spatial externalities of land use as drivers of spatial patterns : even if land is immobile by nature, location's actions affect the whole space through...

The expansion of crop and pastures to the detriment of forests results into an increase in atmospheric CO2. A first obvious cause is the loss of forest biomass and soil carbon during and after conversion. A second, generally ignored cause, is the reduction of the residence time of carbon when...

The ICMS-Ecológico is a fiscal transfer mechanism from states to municipalities, implemented in the early 1990's in Brazil, to reward municipalities for the creation and management of protected areas. This paper investigates the efficiency of this mechanism by testing for the presence of...

The current deliverable report has been prepared in the framework of PLUREL Work Package 1.1 (Economic Scenarios) by Paris 1 Université - Lab. ERASME. The implementation of four scenarios for the PLUREL project allows the description of a range of possible futures in order to evaluate...

The impacts of climate change on human systems depend not only on the level of emissions but also on how inherently vulnerable these systems are to the changing climate. The large uncertainties over future development and structure of societies and economies mean that the assessment of climate...

There are two questions to be considered: a) to which extent the type of framing which may be appropriate for scientific explorations of some issues can also be relevant in a decisionmaking context, in which achieving an agreement among stakeholders is the key problem? b) what is the practical...

Geoengineering, i.e. the use of artificial techniques aiming at cooling the planet, is increasingly considered as a realistic alternative to emission mitigation. Several methods are promising for their capacity to quickly halt global warming at a moderate cost. Such cheap technologies might be...

Socio-economic scenarios constitute an important tool for exploring the long-term consequences of anthropogenic climate change and available response options. They have been applied for different purposes and to a different degree in various areas of climate change analysis, typically in...
