Mike Munger, professor of economics and political science at Duke University and frequent guest of EconTalk, talks with host Russ Roberts about the economics and politics of recycling. Munger argues that recycling can save resources, of course, but it can also require more resources than production from scratch. Some curbside recycling, for example, makes sense, while other forms (such as green glass) may be akin to a form of religious expression rather than a wise policy that is environmentally productive. The conversation is based on Munger's recent essay at the Library of Economics and Liberty.
