Serrano Quintero, Rafael2023-06-162023-06-162023-02-010165-1765https://hdl.handle.net/2445/199363I revisit the productivity slowdown debate by estimating the capital-labor elasticity and the bias of technical change for the U.S. economy under four different models of technical change. One with constant growth rates, one with a structural break in the constant growth rates, one in which growth is linear, and one with flexible time-varying growth rates. I find evidence in support of non-constant growth rates of factor-augmenting technical change. Labor-augmenting technical change growth rates are decelerating, while capital-augmenting technical change is non negligible but vanishes quickly.4 p.application/pdfengcc-by-nc-nd (c) Elsevier B.V., 2023http://creativecommons.org/licenses/by-nc-nd/3.0/es/ProductivitatCapitalTreballCreixement econòmicProductivityCapitalLaborEconomic growthinfo:eu-repo/semantics/article7327852023-06-16info:eu-repo/semantics/openAccess
