Knowledge that Transforms

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.

In this article, the book written by Juan Gabriel Valdes - entitled "Pinochet's Economists: The Chicago School in Chile" - serves as a point of departure. Valdes's account of the way in which University of Chicago economists came to be linked with the Catholic University in Chile in the mid-1950s is summarized, as is his characterization of the manner in which Chilean "Chicago Boys" subsequently won control of the economics faculty there. The centerpiece of Valdes's story is the behavior of the "Chicago Boys" in restructuring Chile's economy in the service of General Pinochet's military dictatorship (1973-89). The article concludes that Valdes's treatment of two additional themes - the cross-cultural transmission of economic ideas and the capacity of Chicago School economists to accommodate to authoritarian regimes - calls for qualification.

We review and critique the empirical literature on the links between investments in children and children's attainments. The primary theoretical perspectives that dominate this literature form the framework for our review. The potential effects on children of family choices and neighborhood characteristics are emphasized. The outcomes of interest include educational attainment, fertility choices, and work-related outcomes such as earnings and welfare recipiency. A set of tables provides details on the existing empirical literature. The focus is on the economics literature, but relevant studies from other social sciences are included as well.

A MONG THE BIG unsettled questions of modrem history and economic history, four loom large-the industrial revolution, the French revolution, the German inflation of the 1920s, and the world depression of the 1930s. All are still studied, debated giving rise to many theories, mostly mono-causal and conflicting. More unsettled questions may be on the way, for example the inflation of the 1980s and the stagnation of the early 1990s. But Gerald Feldman has written a big book that must be taken into account in any discussion of the German inflation, big in many senses, 1000 pages of double-column print (triple columns in the index), 4.48 pounds in weight at my local supermarket, and covering in the order of the subtitle the politics, economics, and sociology of this pathological episode. Specialists in any one discipline may find their own discipline relatively neglected, especially economists who tend to want more theory, as D. C. Coleman indicates, who asserts that theories are what economists make, while historians need evidence (1969, p. 8). The evidence here is prodigious: 49 tables, two-thirds that number of photographs and illustrations, 85 pages of endnotes, 24 pages of bibliography, and a 42-page index, the work of 15 years of study of the subject and 43 earlier publications of Feldman-books, articles, and edited work, some with colleagues, mostly his own. The feast is rich; some economists and economic historians may find it too rich for ready digestion. Feldman is aware of his problem in combining contradictory modes of analysis, but believes it necessary. Partly in a reaction to the work of Carl-Ludwig Holtfrerich whose The German Inflation, 1914-1923 (1986) concludes that the results of the inflation on balance were favorable in giving Germany years of investment and full employment in a largely depressed world and ridding it of private foreign and all internal debt, he asserts:

THE THICK VOLUME under review, by Richard Layard, Stephen Nickell, and Richard Jackman, is an extensive econometric and theoretical study, using time-series and cross section data, of the central tendency of the unemployment rate and its fluctuations in 19 OECD countries since the mid-50s. It thus joins the company of several recent macroeconometric studies of employment determination using international time-series data. Of these it is easily the most far-ranging study to date though in its microscopic examination of social legislation it has somehow neglected a range of macro factors right under its nose. Readers will find an abundance of arresting claims and provocative positions to keep the critical juices flowing. For me the volume is significant not (or hardly at all) as an assemblage of particular modelings and findings but primarily as an early econometric expression of the paradigm shift we are now witnessing in macroeconomics. Once nearly made extinct by a neoclassical winter, a school of economists are today furiously at work on unemployment considered as an equilibrium phenomenon' springing from en-
