What is slowing American innovation?
Core argument: The decline in American innovation is attributed to an unconstrained supply of cheap labor from China and Mexico, a surplus of domestic labor after the recession, and a long-term decline in research productivity.
The decline in American innovation is attributed to several factors, including an unconstrained supply of cheap labor from China and Mexico, a surplus of domestic labor post-recession, and a long-term decline in research productivity. Despite high off-trend productivity gains from the internet, these are unsustainable. A shortage of talent and the difficulty of achieving breakthroughs in general-purpose technologies like AI and quantum computing further hinder progress. The shift from centralized manufacturing to decentralized services has slowed productivity growth, while high real estate prices in growing cities limit medium-skilled migration. Despite these challenges, US productivity growth has accelerated relative to other high-wage countries, suggesting that innovation may not be entirely dead but rather evolving in new directions.



Ed Comment:What killed innovation? 1) unconstrained supply of cheap Chinese/Mexican/immigrant labor; 2) surplus of domestic labor and capacity coming out the recession (just now tightening); 3) long-term decline in research productivity interrupted by unusually high off-trend line productivity gains from internet; i.e., probably not sustainable; 4) shortage of talent; rest of world's talent contributing almost nothing 4) J-curve--next breakthrough of general purpose innovation (AI, quantum computing, driverless car, cure for cancer, etc.) have proven very hard to crack, i.e., progress is, in part, exogenously determined; 5) shift from centralized command and control manufacturing with productivity growth largely driven by engineered capital investment to decentralized, hard-to-manage services with much slower productivity growth; 6) low-skilled workforce has been largely left unsupervised as talent pursues more valuable opportunities. 7) sky-high real estate prices in fastest growing cities precludes medium-skilled migration.Like running a marathon, exogenously given hilly terrain has a big effect on the pace. Best measure is productivity gains relative to rest of high-wage world. By that measure, US productivity growth has accelerated.
