"The Half-Life of Policy Rationales" argues that the appropriateness of policy depends on the state of technology, and that the justifications for many public policies are dissolving as technology advances. As new detection and metering technologies are being developed for highways, parking, and auto emissions, and information becomes more accessible and user-friendly, this volume argues that quality and safety are better handled by the private sector. As for public utilities, new means of producing and delivering electricity, water, postal, and telephone services dissolve the old natural-monopolies rationales of the government. This volume includes essays on marine resources, lighthouses, highways, parking, auto emissions, consumer product safety, money and banking, medical licensing, electricity, water delivery, postal service, community governance, and endangered species. The editors have mobilized the hands-on knowledge of field experts to develop theories about technology and public policy. "The Half-Life of Policy Rationales" will be of interest to readers in public policy, technology, property rights, and economics.
