Protecting Endangered Species in the United States is a collection of original papers by economists, biologists and political scientists with a common theme — protecting species at risk while safeguarding social order is a policy challenge that entangles biology, politics, and economics. The volume begins by assessing the biological needs that define the endangered species problem. The authors then explore the political realities that delimit the debate — who pays the costs and receives the benefits, and how interest groups affect species protection. The book addresses the economic choices that must be confronted for effective protection strategies including incentive schemes to promote preservation on public and private land.
