Policies to address environmental and natural resource management are often implemented at the group level. The defining feature of such policies is that penalties or rewards are based on group rather than individual performance, or rights are allocated to a group rather than to individuals....

Global climate change poses a threat to the well-being of humans and other living things through impacts on ecosystem functioning, biodiversity, capital productivity, and human health. This paper briefly surveys recent research on the economics of climate change, including theoretical insights...

The 2015 Paris Accord is meant to control our planet's rising temperature. But it may be doing the opposite in gradually, rather than immediately reducing CO2 emissions. The Accord effectively tells dirty-energy producers to "use it or lose it." This may be accelerating their extraction and...

We study how the strength of property rights to individual extractive firms affects a regulator's choice over exploitation rates for a natural resource. The regulator is modeled as an intermediary between current and future resource harvesters, rather than between producers and consumers, as in...

Climate policy is complicated by the considerable compounded uncertainties over the costs and benefits of abatement. We don't even know the probability distributions for future temperatures and impacts, making cost-benefit analysis based on expected values challenging to say the least. There are...

This article studies how liability for environmentally harmful discharges affects the incentives of firms to engage in cleanup and invest in precautions, as well as the incentives of consumers to purchase the goods whose production leads to discharges. Our main conclusion is that making firms...

I examine the risk/return tradeoff for environmental investments, and its implications for policy choice. Consider a policy to reduce carbon emissions. To what extent does the value of such a policy depend on the expected future damages from global warming versus uncertainty over those damages,...

I examine Ronald Coase's criticism of standard regulatory and tax policies to address environmental externalities. I elaborate some of Coase's key points and discuss opportunities for Coasean exchange as an alternative mitigation approach. Regulation, tax, and Coasean exchange, such as through...
