Environmental quality in many developing countries is poor and generates substantial health and productivity costs. However, existing measures of willingness to pay for environmental quality improvements indicate low valuations by affected households. This paper argues that this seeming paradox...

We began this project interested in collecting real-world' insight about how environmental regulation affects the paper industry. Based on conversations with people in the industry and visits to paper mills, we formulated several hypotheses related to technology choice in new mills and the...

We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation—in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to...

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...

In a world of certainty, the design of environmental policy is relatively straightforward, and boils down to maximizing the present value of the flow of social benefits minus costs. But the real world is one of considerable uncertainty -- over the physical and ecological impact of pollution,...

We consider the socially optimal use of solar geoengineering to manage climate change. Solar geoengineering can reduce damages from atmospheric greenhouse gas concentrations, potentially more cheaply than reducing emissions. If so, optimal policy includes less abatement than recommended by...
