This essay revisits the question of instrument choice for the regulation of externalities in the context of climate change. The central point is that the Pigouvian prescription to equate marginal control costs with the expected marginal benefits of damage reduction should guide the design of...

Because of the global commons nature of climate change, international cooperation among nations will likely be necessary for meaningful action at the global level. At the same time, it will inevitably be up to the actions of sovereign nations to put in place policies that bring about meaningful...

Public policies for pollution control, including climate change policies, sometimes allow polluters in one sector subject to an emissions cap to offset excessive emissions in that sector with pollution abatement in another sector. The government may often find it more costly to verify offset...

Understanding and minimizing the transaction costs of policy implementation are critical for reducing tropical forest losses. As the international community prepares to launch REDD+, a global initiative to reduce greenhouse gas emissions from tropical deforestation, policymakers need to pay...

Economic theory developed in the prior literature indicates that under the joint and several liability imposed by the federal Superfund statute, the government should recover more of its costs of cleaning up contaminated sites than it would under nonjoint liability, and the amount recovered...

The view that intergenerational distributive justice and efficiency should be treated separately is familiar, yet controversial. This article elaborates the often-implicit justifications for separate treatment and provides a more express statement of how and when such treatment is appropriate....

Economic theory predicts that individual recycling behavior gravitates toward extremes--either diligent recycling or no recycling at all. Using a nationally representative sample of 3,158 bottled water users, this article finds that this prediction is borne out for consumer recycling of plastic...

Federal action addressing climate change is likely to emerge either through new legislation or via the U.S. EPA's authority under the Clean Air Act. The prospect of federal action raises important questions regarding the interconnections between federal efforts and state-level climate policy...

Carbon markets are substantial and they are expanding. There are many lessons from experiences over the past eight years: fewer free allowances, better management of market-sensitive information, and a recognition that trading systems require adjustments that have consequences for market...

Compliance links between CO2 emission trading programs--where firms regulated under one region's tradable permit program can comply using permits from another region, and vice-versa--are beginning to arise as a vehicle to lower costs, increase liquidity, and strengthen institutions while...
