Until not much more than 20 years ago, economists frequently lamented the fact that they were limited in their empirical analyses to statistical assessments of market behavior, because controlled economic experiments were (thought to be) infeasible, unethical, or both. Much has changed in the intervening years! In this new volume, John List, Michael Price, and their co-authors provide a diverse set of applications of experimental approaches to the environmental economics realm. This is among the most promising of new areas of research in the economics of the environment, and this book provides a superb point of entry for experts and novices alike.' - Robert Stavins, Harvard University, US.
