After nearly two decades of debate and fundamental disagreement, topdown and bottom-up energy-economy modelers, sometimes referred to as modeling ‘tribes', began to engage in productive dialogue in the mid-1990s (IPCC 2001). From this methodological conversation have emerged modeling...

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...

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...

This paper aims at clarifying some conceptual flaws blurring the equity-efficiency debates involved in the setting of objectives of GHGs emissions control beyond 2012. To this end, it carries out numerical experiments that test the viability of agreements grounded on two contrasting target...

This paper addresses the timing of the use of biological carbon sequestration and its capacity to alleviate the carbon constraint on the energy sector. We constructed a stochastic optimal control model balancing the costs of fossil emission abatement, the opportunity costs of lands allocated to...
