Integrated assessment models (IAMs) are economists' primary tool for analyzing the optimal carbon tax. Damage functions, which link temperature to economic impacts, have come under fire because of their assumptions that may be incorrect in significant, but a priori unknowable ways. Here I...

Climate economics has been criticized for ignoring uncertainty, catastrophic changes, and tipping points (Stern 2016). The present paper addresses these issues. We consider multiple climate shocks which are recurring, random, uninsurable, and potentially large. The associated damages and the...

Despite overwhelming scientific evidence for man-made climate change, many people remain skeptical. While this phenomenon of `climate-skepticism' prevents implementation of environmental policies around the globe, it is ignored in economic models of climate change. In this paper I fill this gap...

There are concerns that climate-related physical and political risks are not yet properly reflected in asset prices. To address these concerns, we develop a dynamic asset pricing framework with rare disasters related to climate change. The novelty of this paper lies in linking carbon emissions...

Greenhouse gas policies confront the trade-off between the costs of reducing emissions and the benefits of avoided climate change. The risk of uncertain and potentially irreversible catastrophes is an important issue related to the latter, and one that has not yet been well incorporated into...

The possibility of low-probability extreme events has reignited the debate over the optimal intensity and timing of climate policy. In this paper we therefore contribute to the literature by assessing the implications of low-probability extreme events on environmental policy in a continuous-time...

We propose an integrated methodology to evaluate the four possible socio-economic costs namely direct/indirect and tangible/intangible costs due to adverse consequences of flood. Although SERRA is based on full monetization of costs and benefits of risk, it can allow for other methods of...

A conceptual framework integrating different disciplines has been developed to comprehensively evaluate the benefits of risk prevention. Three main innovations are proposed with regards to the state of the art: (1) to include the social capacities of reducing risk, (2) to go beyond the...

Using a threshold public good experiment, we examine how varying degrees of inequality in resources and differences in risk of loss among players affect the success of group efforts to avoid a common loss. We find that when the poor face greater risk than the rich, contributions and success in...

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, 2009). Such risks are suggested to be an inevitable consequence of scientific uncertainty about the effects of increased...
