The Moynihan Institute of Global Affairs’ Trade, Development and Political Economy Series presents Julieta Caunedo speaking on Occupational Exposure to Capital-Embodied Technical Change.

Factor-biased technical change is at the core of the US labor market dynamics in the post-war era. Concurrently, workers’ occupations have become a key dimension for the anatomy of labor reallocation and inequality. This paper furthers our understanding of the heterogeneity in factor-biased technical change across occupations by providing the first direct measures of capital-embodied technical change (CETC) as well as of the elasticity of substitution between labor and capital at the occupational level. We find that CETC vary substantially across occupations and over time, but it is the heterogeneity in the elasticity of substitution that fuels differences in workers’ exposure to technical change and ultimately sets the direction of the labor reallocation triggered by CETC. We evaluate the impact of CETC in a general equilibrium model of endogenous sorting of workers across occupations of different CETC and substitutability between capital and labor. CETC explains 87% of labor reallocation in the US between 1984 and 2015. In an economy with a common elasticity of substitution between capital and labor, measured differences in CETC can only explain 14.5% of the observed labor reallocation.

We’re Turning 100!

To mark our centennial in the fall of 2024, the Maxwell School will hold special events and engagement opportunities to celebrate the many ways—across disciplines and borders—our community ever strives to, as the Oath says, “transmit this city not only not less, but greater, better and more beautiful than it was transmitted to us.”

Throughout the year leading up to the centennial, engagement opportunities will be held for our diverse, highly accomplished community that now boasts more than 38,500 alumni across the globe.
