September 2017The Productivity Slowdown and the Declining Labor Share: A Neoclassical Exploration
with Gene M. Grossman, Elhanan Helpman, Ezra Oberfield: w23853
We explore the possibility that a global productivity slowdown is responsible for the widespread decline in the labor share of national income. In a neoclassical growth model with endogenous human capital accumulation a la Ben Porath (1967) and capital-skill complementarity a la Grossman et al. (2017), the steady-state labor share is positively correlated with the rates of capital-augmenting and labor-augmenting technological progress. We calibrate the key parameters describing the balanced growth path to U.S. data for the early postwar period and find that a one percentage point slowdown in the growth rate of per capita income can account for between one half and all of the observed decline in the U.S. labor share.
January 2016Balanced Growth Despite Uzawa
with Gene M. Grossman, Elhanan Helpman, Ezra Oberfield: w21861
The evidence for the United States points to balanced growth despite falling investment-good prices and an elasticity of substitution between capital and labor less than one. This is inconsistent with the Uzawa Growth Theorem. We extend Uzawa's theorem to show that the introduction of human capital accumulation in the standard way does not resolve the puzzle. However, balanced growth is possible if schooling is endogenous and capital is more complementary with schooling than with raw labor. We describe balanced growth paths for a variety of neoclassical growth models with capital-augmenting technological progress and endogenous schooling. The balanced growth path in an overlapping-generations model in which individuals choose the duration of their education matches key features of the U.S....
