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.

2 Of the many frustrations of any editor, surely, avoidable delay is the greatest. And this frustration is almost infinitely compounded when in the interim an unexpected death occurs. Professor Ferguson sent this manuscript as a draft; certain questions which he raised in the accompanying letter would normally have been resolved in the exchange of two or three letters or 'phone calls. I placed one call to learn he was ill; rather than press the query, I delayed. When next I 'phoned, I was shocked to learn of his completely unexpected and therefore all the more untimely death. Because the draft he sent contains so much of his own style and vigor, I have elected to print it in this incomplete form. The points he raised in his letter remain unclarified. In the face of this series of events, I have asked Professor Nell to undertake the task initially given to Ferguson. The two rarely saw things in the same way. Thus, the choice of Nell was not intended to finish Ferguson's incomplete assessment. I mention the foregoing simply to explain the unique treatment in these review essays. Of Charles Ferguson's death so little can be said-he was an ebullient souil, and a man of significant originality. -M. P.

The article studies the U.S. earning trends since 1950 and gives explanations for the inequality in earnings. Both slow growth and increased inequality appear in the comparison of adult male earnings distributions for 1979 and 1987. Trends in women's earnings paint a somewhat brighter picture. Women, like men, have experienced slow hourly wage growth and growing wage inequality. But in terms of annual earnings, both factors have been offset by changes in hours worked. The result is a significant increase in the proportion of women who earn $20,000 a year or more. A combination of shifts in supply and shifts in demand is necessary to explain the observed trends between these groups. A critical aspect of supply shifts was the entry into the labor market of the well-educated baby boom generation. Demand shifts can be characterized as a long-term trend toward increasing relative demand for highly skilled workers. The growth in within group earnings inequality has many potential explanations, but it is not well understood and contains opportunities for future research.
