Environmental Catastrophes and Mitigation Policies in a Multi-region World
July 12, 2018

NCAER Conference Room

A seminar on “Environmental Catastrophes and Mitigation Policies in a Multi-region World” with Professor Avinash Dixit, Professor Emeritus at Princeton University was held at NCAER on July 12, 2018. 

 

In his Presentation, Professor Dixit discussed his joint paper with Timothy Besley (LSE) which presents a simple model for assessing the willingness to pay for reductions in the risk associated with catastrophic climate change. The model is extremely tractable and applies to a multi-region world but with global externalities and has five key features. First, neither the occurrence nor the costs of a catastrophic event in any one year are precisely predictable. Second, the probability of a catastrophe occurring in any one year increases as the levels of greenhouse gases in the atmosphere increase. Third, greenhouse gases are a worldwide public bad with emissions from any one country or region increasing the risks for all. Fourth, there is two-sided irreversibility; if nothing is done and the problem proves serious, the climate, economic activity and human life will suffer permanent damage, but if we spend large sums on countermeasures and the problem turns out to be minor or even non-existent, we will have wasted resources unnecessarily. Fifth, technological progress may yield partial or even complete solutions. The framework proposed by the authors can be used to give a sense of the quantitative significance of mitigation strategies. The paper illustrates this for a core set of parameter values.

 

Avinash Dixit is John J. F. Sherrerd ’52 University Professor of Economics Emeritus at Princeton University. Before joining Princeton in 1981, he was assistant professor at the University of California, Berkeley, a fellow of Balliol College, Oxford, and professor at the University of Warwick.
