Offers an easy way for students, academics, journalists, policymakers, and the public to learn about a diverse range of policy issues affecting the environment, energy, transportation, and public health. 'What a great idea! Get 100 qualified individuals, or teams, to produce brief, 2-page analyses of urgent policy issues a nontechnical encyclopedia of current issues in climate, energy, ecology, and related topics. My suggestion: read one each day, and think about it all day. In a hundred days you'll be hugely enriched. Only RFF could do this.' Thomas C. Schelling, University of Maryland, Winner of the Nobel Prize in Economics 'This unique book offers an impressive set of brief, understandable, and authoritative analyses of 100 issues in the important policy areas on which recent RFF research has focused. It belongs on the bookshelf of everyone who has ever encountered an unfamiliar issue in this broad domain and wondered,What is the best thinking on this? It is a terrific source of readings for courses dealing with public policy.' Richard Schmalensee, Massachusetts Institute of Technology 'The short essays in this volume provide a treasure trove of interesting analyses of a variety of important economic policy issues. Instructors in economics and public policy courses will particularly value the clear, sensible, and student-friendly fashion in which microeconomic tools are employed.' Harvey S. Rosen, Princeton University 'In this refreshingly different approach to environmental policy, we hear from a very wide variety of the world's environmental economists and policy researchers, with short and pointed opinion pieces. This is great reading and should be valuable for anyone who wishes to appreciate the nuances of solving many of today's pressing environmental problems.' Charles D. Kolstad, University of California, Santa Barbara
