'This book of essays on the economics of regulation is comprehensive and authoritative, and is particularly noteworthy for its emphasis on European as well as American regulatory methods. The international perspective is important because of the long history of regulatory failures on both continents, the increasing integration of the economies of both continents, and the resulting need of both regulatory cultures to learn from each other.' - Richard A. Posner, Judge, United States Court of Appeals for the Seventh Circuit and University of Chicago Law School, US.
