Uncertainty plays a key role in the economics of climate change, and the discussions surrounding its implications for climate policy are far from settled. We give an overview of the literature on uncertainty in integrated assessment models of climate change and identify some future research...

-probability extreme events on environmental policy in a continuous-time real options model with “tail risk”. In a nutshell, our results … indicate the importance of tail risk and call for foresighted pre-emptive climate policies …

Modeling the price risk of CO2 certificates is one important aspect of integral corporate risk management related to … emissions trading. The paper presents a risk model which may be the basis for evaluating the risk of emission certificate prices …

We present a simple approach to transform a deterministic numerical model, where several agents simultaneously make decisions, into a stochastic model. This approach, which builds on scenario aggregation, a numerical method developed to solve decision problems under uncertainty, is used to build...

Sensitivity (proportionality) of willingness to pay to (small) risk changes is often used as a criterion to test for …,005 respondents were asked their willingness to pay (WTP) for preventing an increase in risk by 1/42,500 and 3/42,500, respectively …. WTP for the higher risk variation is significantly higher than WTP for the lower risk change. We find evidence that those …

We investigate how consumers respond to uncertainty about CO<sub>2</sub> emission size. In an incentivized online experiment, participants can acquire a valuable good that emits an unknown amount of CO<sub>2</sub>. We find that beliefs about emission size are strongly predictive of purchases, even exceeding the...

The United Nations Sendai (2015) framework aims to reduce disaster risk. We offer a careful definition and computation … of the individual and property risk targets. Selecting the largest and better studied class of “natural disasters” over … the period 1970-2018, we show that individual risk is “likely” falling, that property risk is neither rising nor falling …

This study moves beyond recent catastrophe or tipping point studies with arbitrary risk … introduced here informs risk management strategies that balance uncertain future climate change impacts with the costs of …

Models (IAMs), which assumes no risk sharing across region, we introduce global risk sharing via a market for state … across regions. We estimate that such risk sharing scheme of climate risks could lead to welfare gains reducing the global … for considering risk sharing in IAMs, but also for potentially welfare increasing negotiations about sharing risks of …

To shed a light on these questions, we analyse a sample of 69 transition risk metrics delivered by 9 different … climate transition risk providers and covering the 1,500 firms of the MSCI World index. Our findings show that convergence … between metrics is significantly higher for the firms most exposed to transition risk. We also show that metrics with similar …
