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...

California and Sweden are both leaders in green regulations and actions. In both there is a substantial political base for environmental regulation, yet the path to regulation in these two political entities is quite different. California emphasizes command and control regulations while Sweden...
