|June 2020||Transatlantic Technologies: The Role of ICT in the Evolution of U.S. and European Productivity Growth|
with Robert J. Gordon: w27425
We examine the role of the ICT revolution in driving productivity growth behavior for the United States and an aggregate of ten Western European nations (the EU-10) from 1977 to 2015. We find that the standard growth accounting approach is deficient when it separates sources of growth between ICT capital deepening and TFP growth, because much of the effect of the ICT revolution was channeled through spillovers to TFP growth rather than being limited to the capital deepening pathway. Using industry-level data from EU KLEMS, we find that most of the 1995-2005 U.S. productivity growth revival was driven by ICT-intensive industries producing market services and computer hardware. In contrast the EU-10 experienced a 1995-2005 growth slowdown due to a paucity of ICT investment, a failure to capt...
|March 2019||The Industry Anatomy of the Transatlantic Productivity Growth Slowdown|
with Robert J. Gordon: w25703
By merging KLEMS data sets and aggregating over the ten largest Western European nations (EU-10), we are able to compare and contrast productivity growth up through 2015 starting from 1950 in the U.S. and from 1972 in the EU-10. Data are provided at the aggregate level, as well as for 16 industry groups within the total economy and 11 manufacturing sub-industries. The analysis focuses on outcomes over four time intervals: 1950-72, 1972-95, 1995-2005, and 2005-15. We interpret the EU-10 performance as catching up to the U.S. in stages, with its rapid growth of 1950-72 representing a delayed adoption of the inventions that propelled U.S. productivity growth in the first half of the 20th century, and the next EU-10 stage for 1972-95 as imitating the U.S. outcome for 1950-72. We show that both...
