This presentation has two parts. The first part is more theoretical. We will examine the definition of Integrated Assessment Models of Climate Change and identify their main aims. We will also have look at the differences between climate and socioeconomic models. The second part will be applied....

Climate change is one of the biggest challenges facing humankind for the next century. We expose how we build a Model about the Dynamics of Inertia and Adaptability in energy systems (DIAM) to study the question \"Shall we wait another decade before taking costly measures to curb greenhouse...

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...

This paper discusses aspects of risk and uncertainty relevant in an interdisciplinary assessment of climate change policy. It opposes not only the objective approach versus the subjective approach, but also situations when precise probabilities are well founded versus situations of broader forms...
