This paper examines the impact of Knightian uncertainty upon optimal climate policy through the prism of a continuous-time real option modelling framework. We analytically determine optimal intertemporal climate policies under ambiguity. Additionally, numerical simulations are provided to...

Recent theoretical work in the economics of climate change has suggested that climate policy is highly sensitive to fat-tailed' risks of catastrophic outcomes (Weitzman, 2009b). Such risks are suggested to be an inevitable consequence of scientific uncertainty about the effects of increased...

Klimaanpassungspolitik wird in Deutschland auf verschiedenen politischen Ebenen betrieben. Dieses Papier untersucht auf Grundlage der ökonomischen Theorie der Anpassungspolitik Defizite dieser Politikansätze. Diese liegen in erster Linie in den folgenden Bereichen: unklare Abgrenzung von...

The paper derives the optimal carbon tax in closed-form from an integrated assessment of climate change. The formula shows how carbon, temperature, and economic dynamics quantify the optimal mitigation effort. The model’s descriptive power is comparable to numeric models used in policy...

We study a dynamic stochastic general equilibrium model in which agents are concerned about model uncertainty regarding climate change. An externality from greenhouse gas emissions damages the economy's capital stock. We assume that the mapping from climate change to damages is subject to...

Climate change is predicted to substantially alter forest growth. Optimally, forest owners should take these future changes into account when making rotation decisions today. However, the fundamental uncertainty surrounding climate change makes predicting these shifts hard. Hence, this paper...

The paper clarifies the link between changes in risk aversion and the effect on the consumption discount rate. In a general framework that can cope with various forms of uncertainty, it is shown that the response of the consumption discount rate to a change in risk aversion depends on some...

Aim: Provide a summary of the expressed views, presentations and discussions during the ISINI14 (2020) online conference. Design: Next to rather traditional but this time online presentations, the discussions not only took place by way of oral communication, but also via an online tool. The...

Uncertainty has an almost negligible impact on project value in the economic standard model. I show that a comprehensive evaluation of uncertainty and uncertainty attitude changes this picture fundamentally. The analysis relies on the discount rate, which is the crucial determinant in balancing...
