"Jorgenson and his talented coauthors Ho and Stiroh have been among the leaders in analyzing the post-1995 revival in American productivity growth. Notable in this volume is their pathbreaking analysis of human capital, with its prediction that the contribution of higher labor quality to U.S. economic growth will steadily diminish over the next few decades. Lovers of controversy will relish the authors' unique interpretation of 'the demise' of growth accounting." Robert J. Gordon, Stanley G. Harris Professor in the Social Sciences, Department of Economics, Northwestern University
