Human Capital and the World Technology Frontier
研究了1870-2009年21个工业化国家教育程度及其与世界技术前沿距离的交互作用对生产率增长的影响，发现教育变化和与前沿距离的交互作用显著影响生产率增长。
This paper examines the productivity growth effects of educational attainment and its interaction with the distance to the world technology frontier, which is the percentage distance to the country with the highest total factor productivity (TFP) (the United Kingdom or United States), while allowing for the endogeneity of educational attainment in some of the estimates. For this purpose, a new annual data set for educational attainment is constructed for 21 industrialized countries over the period from 1870 to 2009. The results show that changes in educational attainment and the interaction between education and the distance to the frontier, as predicted by Schumpeterian growth theory, have been influential for productivity growth over the past 140 years. © 2014 The President and Fellows of Harvard College and the Massachusetts Institute of Technology
