[영문]AbstractUnemployment: Macroeconomic Performance and the Labour Marketby Richard Layard, Stephen Nickell, and Richard Jackman (Oxford University Press 2005) is the second edition of a book first published in 1991. The second edition is identical to the first except for a long introduction, which reviews the conclusions of the first edition in the light of the following fifteen years. I basically agree with the authors that the book's framework and conclusions have withstood the test of time very well. I then assess progress since 1991 and point to a number of directions in which progress needs to be achieved
