David Card and Alan B. Krueger received the IZA Prize in Labor Economics in 2006 for their outstanding contributions to the field. This volume provides an overview of their most important work on school quality, differences in wages across groups in the US, and the effect of changes in the minimum wage on employment and wage setting. I found that the book offers a timely discussion regarding a much politicized debate around the responsibility of societies to invest more in education and on their young people. The book is a gold mine of data which can spark lively discussions among educationalists, sociologists and economists.
