This paper provides an overview of how economists think about climate change impacts with a focus on Asia. It is designed to discuss the steps along the causal chain from physical impacts to impacts on human and natural systems. It starts with a summary of the projected physical impacts of...

Global climate change poses significant risks to the California economy. Recognizing and responding to these threats, Governor Schwarzenegger signed Executive Order #S-3-05 (Schwarzenegger 2005) which called for a 30 percent reduction below business-as-usual of greenhouse gas emissions by 2020...

In the absence of a global climate agreement, countries employ local policies to curb pollution and introduce clean energy. These policies limit domestic consumption of a traded energy source but increase exports thus improving a country’s energy balance and its balance of trade. While...

We introduce a version of the DICE-2007 model designed for uncertaintyanalysis. DICE is a wide-spread deterministic integrated assessment model of climatechange. Climate change, long-term economic development, and their interactionsare highly uncertain. The quantitative analysis of optimal...

The paper incorporates qualitative differences of probabilistic beliefs into a rational (or normatively motivated) decision framework. Probabilistic beliefs can range from objective probabilities to pure guesstimates. The decision maker in the present model takes into account his confidence in...

We analyze the impact of damage uncertainty on optimal mitigation policies in the integrated assessment of climate change. Usually, these models analyzeuncertainty by averaging deterministic paths. In contrast, we build a consistentmodel deriving optimal policy rules under persistent...
