Productivity growth and levels in France, Japan, the United Kingdom and the United States in the Twentieth century

"This study compares labor and total factor productivity (TFP) in France, Japan, the United Kingdom and the United States in the very long (since 1890) and medium (since 1980) runs. During the past century, the United States has overtaken the United Kingdom and become the leading world economy. During the past 25 years, the four countries have also experienced contrasting advances in productivity, in particular as a result of unequal investment in information and communication technology (ICT).The past 120 years have been characterized by: (i) rapid economic growth and large productivity gains in all four countries; (ii) a long decline of productivity in the United Kingdom relative to the United States, and to a lesser extent also to France and Japan, a relative decline that was interrupted by the Second World War (WW2); (iii) the remarkable catching-up to the United States by France and Japan after WW2, that stopped in the case of Japan during the 1990s. Capital deepening (at least to the extent this can be measured) accounts for a large share of the variations in performance; increasingly during the past 25 years, this has meant ICT capital deepening. However, the capital contrib
