Virtually all of contemporary macroeconomics is underpinned by a Phillips curve of one variety or another, and this volume collects for the first time the major works of one of the great economists. In addition to twelve substantive pieces, twenty-nine economists including Lawrence Klein, James Meade, Thomas Sargent, Peter Phillips, David Hendry, William Baumol, Richard Lipsey and Geoffrey Harcourt highlight and interpret Phillips' ongoing influence. This volume also contains six of Phillips' previously unpublished essays, four of which were long thought to have been lost.
