I recently listened to an old EconTalk podcast featuring Clemson economist Bruce Yandle. Yandle is famous for the "Bootleggers and Baptists" theory of regulation. In this episode, he discusses an alternative to the current form of federal environmental regulation. Specifically, he talks about the pre-1970s era when state-level common law settled disputes between parties in regard to environmental quality.
Yandle begins by discussing the tragedy of the commons or the commons problem. For those who don't know, the tragedy of the commons refers to the problem we face with public access to scarce resources. He talks about the stages of evolution of property rights and introduces his juxtaposition of common law approaches to environmental policy to administrative regulation with some historical examples. I'll leave those for the interested listener (the podcast is about 1 hour in length, the extra run time at the end is devoted to a comment by the host).
Here are several of Yandle's points that make his case for the common law approach vis-a-vis the current regulatory approach:
- The state- and city-level common law standard prevalent before the 1970s applied to the parties to the dispute, no one else, though a particular case might be cited in the decision of another. The basic principle was that you didn't have a right to pollute your neighbor's property without their permission.
- Many businesses seeking to discharge waste went to downstream landowners and offered to pay to offset the water quality deterioration rather than purchase the land outright (though this was common as well). This makes a Coasian point: there must be someone who is harmed by the discharge for an externality to exist. Getting rid of all pollution is not likely to be cost-effective. The downstream property holder had a right to water quality based on his or her ownership of the land.
- Common law generally works on a case-by-case cost-benefit standard whereas regulations don't. The license to discharge or the technological standard required to mitigate pollution applies to all, Yandle says that this implies that the damage done by the pollution isn't legally relevant, only the rules laid out by the regulator.
- Though differential access to legal services is potentially an issue, district attorneys (or tort law, in my amateur, non-lawyer opinion) could be used to solve this problem.
- Did the common law standard work well? Previous research indicates that progress in water and air quality before 1970 was roughly indistinguishable from progress after.
- Yandle is positive about the prospect of using the EPA as an environmental research organization and expert witness in environmental common law cases.
- I can't resist one example. Anglers' associations in England and the English part of Canada have successfully brought suit against polluters and improved water quality under the existing common law standard. This is possible because a landowner also owns the wildlife on his or her property. Yandle says that this is not so in the US; that wildlife are considered public property here. Anglers' associations in the UK have been so successful in common law courts and are now so powerful that all they have to do is make a phone call to a business inadvertently killing fish in a stream or river and the problem is fixed quickly and quietly. Overall, Yandle makes a persuasive case in favor of environmental common law.
