I don’t think it makes sense to compare America’s growth vs China or India’s growth over this period.
Yes, the countries were adopting similar technologies, but when America was adopting them, they were adopting those technologies at the technological frontier. When China and India were adopting them, they were not. It’s easier to grow by adopting already invented technologies than by inventing new ones. This is essentially the logic behind Solow-Swan convergence between rich and poor countries, which as an economic model has held up pretty well to what we observe in the real world.
As advocates of progress studies, we should be looking to see if it is possible to accelerate the rate of frontier growth. There are good reasons to think it might be. As others mentioned, J. Storrs Hall lays out some technologies that were not adopted for various reasons. AI could greatly accelerate technological and economic development. But also, we’ve also observed upshifts in economic growth in the past. Post-Industrial revolution, the economic growth rate, at the frontier and per capita, was about 1% a year, then about 1.5% a year after 1880, and about 2.5% a year after 1930 (I think—my memory is a little fuzzy on the exact numbers here). Thomas Philippon’s paper (summarized by the author in Tweet form here) offers some interesting insights into why this might be. We’ve seen the story of accelerating frontier growth before—the question is why haven’t seen it again in the past 50 years.
Hey folks, I’m Erik. I heard about Progress Studies through an interest in economic history. I’ve always been very interested in the Industrial Revolution, why development occurs or why it doesn’t, and what we could do to accelerate the rate of technological progress. Progress Studies appealed to me because it’s a group of people very interested in those same questions through a modern lens—what works and what doesn’t to increase industrial and technological advancement in the modern day?
As some might guess from my earlier comment, my background is in economics. My day job is in business intelligence, I also have a startup project related to zoning/real estate I’m working on the side. I’m based out of the Philly area, I encourage all other Philly area folks to join the community group! Once we have a few people, let’s find an evening we can do a happy hour or something. Looking forward to connecting with different people!
