The 1990s, particularly the last half of the decade, presented a special challenge to the conventional wisdom. Few would have asserted that unemployment could be pushed much below (or possibly even to) 5.5 or 6.0 percent without an unacceptable acceleration in the rate of price inflation. This consensus came from the acceptance of the Phillips curve and the NAIRU (nonaccelerating inflation rate of unemployment), and so ingrained was this orthodoxy that most policymakers accepted it. Is the NAIRU dead?

The Russell Sage Foundation and the Century Foundation believed that the 1990s required a closer examination to see what we could learn from this seemingly unusual period. They asked Robert Solow and Alan Krueger to assemble the set of topics and authors that resulted in this volume. The book is divided into four parts.
