Claudia Goldin, professor of economics at Harvard University, program director for the Development of the American Economy, and research associate at the National Bureau of Economic Research, and Lawrence F. Katz, professor of economics at Harvard University and research associate at the National Bureau of Economic Research, conducted historical research into the impact of technological and educational developments on the American economy during the years 1910 to 1960. They explored the reasons for the tremendous increase in high school attendance and graduation through the mid-1930s, and addressed the economic consequences of rapid educational advances on productivity and wages. In the current era of renewed technological advances and a declining educational system, Goldin and Katz offered a fresh perspective on rising inequality by examining the historic interplay of technology, education, and human capital.
