With climate change as prototype example, this paper analyzes the implications of structural uncertainty for the economics of low-probability, high-impact catastrophes. Even when updated by Bayesian learning, uncertain structural parameters induce a critical tail fattening of posterior-predictive distributions. Such fattened tails have strong implications for situations, like climate change, where a catastrophe is theoretically possible because prior knowledge cannot place sufficiently narrow…

In this article, I revisit some basic issues concerning structural uncertainty and catastrophic climate change. My target audience here are general economists, so this article could also be viewed as

Fat-Tailed Uncertainty, Learning, And Climate Policy

Low-probability, high-impact risks are critical features of climate change economics; however, there are many unanswered policy and modeling questions about the implications of fat-tailed

High impact, low probability? An empirical analysis of risk in the economics of climate change

To what extent does economic analysis of climate change depend on low-probability, high-impact events? This question has received a great deal of attention lately, with the contention increasingly

Revisiting Fat-Tailed Uncertainty in the Economics of Climate Change

Expected Utility and Catastrophic Risk in a Stochastic Economy-Climate Model

Abstract We analyze a stochastic dynamic finite-horizon economic model with climate change, in which the social planner faces uncertainty about future climate change and its economic damages. Our

The Social Cost of Stochastic and Irreversible Climate Change

There is great uncertainty about the impact of anthropogenic carbon on future economic wellbeing. We use DSICE, a DSGE extension of the DICE2007 model of William Nordhaus, which incorporates beliefs

The Extreme Uncertainty of Extreme Climate Change : An Overview and Some Implications

The possibility of catastrophic climate change is characterized by deep structural uncertainties in the science coupled with an economic inability to evaluate meaningfully the welfare losses from

Climate Change, Catastrophic Risk and the Relative Unimporartance of Discounting

Discounting in the presence of catastrophic risk is a hotly debated issue, in particular with respect to climate change. Many scientists and laymen concerned with potentially catastrophic impacts

Growth and Uncertainty in the Integrated Assessment of Climate Change

We analyze the impact of uncertainty about economic growth in the integrated assessment of climate change on optimal mitigation policies. For this purpose, we construct a close relative of the DICE

Why Is Climate Sensitivity So Unpredictable?

It is shown that the breadth of the distribution and, in particular, the probability of large temperature increases are relatively insensitive to decreases in uncertainties associated with the underlying climate processes.

The Stern Review calls for immediate decisive action to stabilize greenhouse gases because "the benefits of strong, early action on climate change outweighs the costs." The economic analysis

Is the Uncertainty about Climate Change too Large for Expected Cost-Benefit Analysis?

Cost-benefit analysis is only applicable if the variances of both costs and benefits are finite. In the case of climate change, the variances of the net present marginal costs and benefits of

The focus of climate policy so far has been on reducing the accumulation of greenhouse gases. That approach, however, requires broad international cooperation and, being expensive, has been hindered
