We specify a stochastic economy-climate model, adapting Nordhaus' deterministic economy-climate model by allowing for Weitzman-type stochasticity. We show that, under expected power utility, the model is fragile to heavy-tailed distributional assumptions and we derive necessary and sufficient...

Uncertainty is an important aspect of the environmental issue quite a few of the basic functions describing the role of the environment for the economic system are not well known "ex ante". Emissions interact through rather complex and intricate systems and pollutants such as DDT accumulate...

The analysis of climate change is confronted with large uncertainties that need to be taken into account to arrive at meaningful policy recommendations. The main contribution of economics to this interdisciplinary task is to provide formal frameworks and techniques for analyzing climate policy...
