A Vision of the Growth Process in a Technologically Progressive Economy: the United States, 1899-1941.
257/2015 Gerben Bakker, Nicholas Crafts and Pieter Woltjer
We develop new aggregate and sectoral Total Factor Productivity (TFP) estimates for the United States between 1899 and 1941 through better coverage of sectors and better measured labour quality, and show TFP-growth was lower than previously thought, broadly based across sectors, strongly variant intertemporally, and consistent with many diverse sources of innovation. We then test and reject three prominent claims. First, the 1930s did not have the highest TFP-growth of the twentieth century. Second, TFP-growth was not predominantly caused by four leading sectors. Third, TFP-growth was not caused by a ‘yeast process’ originating in a dominant technology such as electricity.
