The effects of climate change on natural systems will be substantial, wide-spread, and likely irreversible. Warmer temperatures and changing precipitation patterns have already contributed to forest dieback and pushed some species towards extinction. Natural systems contribute to human welfare...

For benefit-cost analysis of policies with respect to environmental and natural resources, economic researchers often require monetized values of households’ willingness to pay for reductions in risks to human life and health. I briefly recap some of the main issues in the related task of...

We review key developments in the cost-benefit analysis of water projects, including conceptual and empirical issues. We emphasize general equilibrium and dynamics, in particular the links between economic and ecological systems.

Federal regulatory policy and the evaluation of regulations using benefit-cost analysis continue to be quite contentious. Advocates for more regulation claim that benefit-cost analysis loses information and impedes our understanding of the real beneficial consequences of regulatory action....

The value of mortality risk reduction is an important component of the benefits of environmental policies. In recent years, the number, scope, and quality of valuation studies have increased dramatically. Revealed-preference studies of wage compensation for occupational risks, on which analysts...

This paper uses a public economics framework to review evidence from randomized trials on domestic water access and quality in developing countries and to assess the case for subsidies. Water treatment can cost-effectively reduce reported diarrhea. However, many consumers have low willingness to...

The methods that scientific and technical experts have developed for constructing quantitative assessments of health and safety risks have major shortcomings as tools for decision analysis. We use a model of cost-effective risk management under uncertainty to discuss shortcomings of standard...

In many countries, environmental policies and regulations are implemented to improve environmental quality and thus individuals' well-being. However, how do individuals value the environment? In this paper, we review the life satisfaction approach (LSA), which represents a new nonmarket...

Over the past two decades, hundreds of stated preference studies have been conducted in less-developed countries. This article examines what has been learned on the methodological front from stated preference research, and it summarizes the empirical evidence from stated preference studies about...

We consider health and environmental quality in developing countries, where limited resources constrain behaviors that combat enormously burdensome health challenges. We focus on four huge challenges that are preventable (i.e., are resolved in rich countries). We distinguish them as special...
