Capital Embodied Structural Change by Elisa Keller

Join us for this weeks Macroeconomics Research Seminar, Autumn Term 2023.

Elisa Keller, from the University of Exeter Business School, will present this weeks Macroeconomics seminar on Capital Embodied Structural Change.

Abstract

Structural change is one of the most robust features that characterize economic growth. Capital-embodied technological change (CETC), or the decline in the marginal consumption cost of investment, is a prominent source of economic growth. What is the role of CETC for structural change? We build new measures of CETC in the US from the decline in the price of new capital goods used in each sector between 1948 and 2020. We document faster CETC in services than in manufacturing than in agriculture; and show that CETC, when paired with the observed path of the labor share, can trace the dynamics of the price of output in agriculture relative to manufacturing, and to a less extent, that in services relative to manufacturing. To quantify the role of CETC for structural change we build a parsimonious model that accommodates sector-specific CETC through the usage of distinct bundles of equipment, as well as an endogenous sectoral labor share, which mediates the passthrough between CETC and structural change. Through counterfactuals, we find that CETC is the primary driver of the reallocation of output away from agriculture and accounts for a third of the reallocation towards services. These findings emphasize the importance of the composition of sectoral investment for structural change.

This seminar will be held on campus in the Economics Common Room at 1.30pm on Tuesday 5th December 2023. This event is open to all levels of study and is also open to the public. To register your place, please contact the seminar organisers.

This event is part of the Macroeconomics Research Seminar Series.
