SMU SOE Seminar Series (March 20, 2024): Technological Waves and Local Growth

Please click here if you are unable to view this page.

ABSTRACT We develop a spatial model of endogenous growth via frictional knowledge diffusion to examine the effect of technological waves—defined as long-term shifts in the importance of specific knowledge fields—on local population dynamics. We calibrate the model using a new dataset of historical geolocated patents spanning over one hundred years. We find that frictions to idea diffusion across locations and technological fields account for more than half of the empirical relationship between exposure to technological waves and local growth in the United States during the twentieth century. Counterfactual experiments suggest that future technological scenarios may have large geographical effects. Keywords: Cities, Population Growth, Technology Diffusion, Innovation, Patents. JEL Codes: R12, O10, O30, O33, O47. Click here to view the CV. Click here to view the paper.
