Two decades have passed since the Clean Air Act Amendments of 1990 launched a grand experiment in market-based environmental policy: the SO₂ cap-and-trade system. That system performed well but created four striking ironies: First, by creating this system to reduce SO₂ emissions to curb acid...

Preserving endangered species on private land benefits the public, but may confer cost on landowners if property is 'taken.' Government compensation to landowners can offset costs, although the Endangered Species Act does not require compensation. The authors survey private economic incentives...

The Endangered Species Act of 1973 is one of our most far-reaching and controversial environmental laws. While the benefits of protecting endangered species accrue to the entire nation, a significant fraction of the costs are borne by the private landowners who shelter about 90 percent of the...

About 45 years ago a few economists offered the novel idea of trading pollution rights as a way of meeting environmental goals. Such trading was touted as a more cost-effective alternative to traditional forms of regulation, such as specific technology requirements or performance standards. The...

This paper seeks to assess the current status of water quality trading and to identify possible problems and solutions. Water pollution permit trading programs have rarely been comprehensively described and analyzed in the peer-reviewed literature. Including active programs and completed or...

A person may be willing to make an economic tradeoff to assure that a wilderness area or scenic resource is protected even if neither that person nor (perhaps) anyone else will actually visit this area. This tradeoff is commonly labeled "passive use value." Contingent valuation studies ask...

The purpose of this article is to examine the preservation of biodiversity as an economic problem. Using a very simple prototype model, the authors discuss how to include diversity in the objective function and how to develop a simple cost-benefit ranking criterion for ordering priorities. Then...

Economists have made great progress in understanding the incentives and behavior of actors who operate outside of traditional economic markets, including voters, legislators, and bureaucrats. The incentives and behavior of judges, however, remain largely opaque. Do judges act as neutral...
