The book begins with a quote from J.H. Dales’ Pollution, Property, and Prices, "If it is feasible to establish a market to implement a policy, no policy-maker can afford to do without one." This book provides important evidence in support of Dales’ statement. The book is a thorough examination of the first several years of the U.S. Acid Rain Program. This innovative program uses a cap-and-trade approach, rather than the traditional command-and-control approach, to reduce sulfur dioxide (SO2) emissions. The book offers substantial evidence of the program’s success. The analysis is of both practical and scientific importance. From a practical viewpoint, the acid rain program is an ambitious effort to reduce a major pollutant. It is important for us to understand whether the program is successful and how it might be improved. From a scientific viewpoint, the authors’ analysis provides a framework and methodology for evaluating similar programs. There is much we can learn about effective regulation from the analysis

Many barriers to the international movement of capital across national boundaries have been dismantled over the course of the last 20 years. Financial integration was greatly enhanced by the removal of capital controls on the part of the United States, Germany, Canada, Switzerland, and the Netherlands after 1973; the recycling of surpluses to developing countries through the Euromarkets in the 1970's; the removal of capital controls in the United Kingdom and Japan beginning in 1979; financial integration among European Community countries, including France and Italy, in preparation for 1992; recent moves toward financial liberalization in smaller countries in the Pacific; and the steady process of technical and institutional innovation that has proceeded around the world. Some popular tests of international capital mobility, however, appear to show anomalous results. Martin Feldstein and Charles Horioka upset conventional wisdom in 1980 when they concluded that changes in countries' rates of national saving had very large effects on their rates of investment and interpreted this finding as evidence of low capital mobility. The argument
