L'utilisation du calcul économique sur le très long terme fait l'objet de critiques quipeuvent aller jusqu'à un rejet pur et simple, en particulier en raison de la technique del'actualisation qui, en écrasant le poids du long terme, viendrait en contradiction avec leprincipe de précaution....

We examine the international distribution of expenditures for the provision ofa global, long-term and uncertain public goods from the point of view of abenevolent planner. Even assuming a "no-redistribution" constraint, first periodexpenditures are in general progressive with income, and...

Extreme events are one of the main channels through which climate and socio- economic systems interact and it is likely that climate change will modify their probability distributions. The long-term growth models used in climate change as- sessments, however, cannot capture the effects of such...

To analyze the response of cities to urban policies or transportation shocks, describing a succession of stationary states is not enough, and urban dynamics should be taken into account. To do so, the urban economics model NEDUM is proposed. This model reproduces the evolution of a monocentric...

Climate change damage assessments are commonly based on long term growth models that neglect disequilibrium processes, assumed to be transient over short periods. This thesis highlights, from a set of modelling exercises, how important the short-term transients and the endogenous economic...

La méthode des analogues climatiques consiste à déterminer un endroit doté aujourd'hui d'un climat comparable à celui que l'on prédit à la fin du siècle. Ce travail représente ainsi ce que signifie le changement climatique pour Paris et 8 autres grandes villes européennes. Dans le...

Decision makers facing abatement targets need to decide which abatement measures to implement, and in which order. Measure-explicit marginal abatement cost curves depict the cost and abating potential of available mitigation options. Using a simple intertemporal optimization model, we...

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...

This paper explores the relationships between climate change and security. Potential threats from climate change, as a unique source of stress or together with other factors, to human security are first examined. Some of the most explicit examples illustrate this section : food security, water...

Despite the inextricable link between oil scarcity and climate change, the interplay between these two issues is paradoxically an underworked area. This article uses a global energy-economy model to address the link between future oil supply and climate change and assesses in a common framework...
