Comment on “Structural transformation and the rise of information technology” by Gallipoli and Makridis

“Structural transformation and the rise of information technology” by Gallipoli and Makridis provides compelling evidence on the effects of increasingly productive IT-intensive occupations on within-sector productivity growth. I discuss their results and link them to patterns of aggregate productivity growth. While there are limits to aggregate conclusions from within-sector patterns, their findings provide rich empirical restrictions on equilibrium models of structural transformation.
