Neil Irwin reports via Axios: The dearth of productivity growth over the last couple of decades has held back incomes in the U.S. and other rich countries, according to a report out Wednesday from the McKinsey Global Institute, the research arm of the global consultancy. Productivity growth has been weak in the U.S. and Western Europe since the 2008 global financial crisis, but things looked better among many emerging markets. The McKinsey report finds that global labor productivity growth was 2.3% a year from 1997 to 2022, a rapid rate that has increased incomes and quality of life in large parts of the world. China and India account for the largest portion of that surge -- half of overall global productivity improvement, with other emerging markets accounting for another 25%, led by Central and Eastern Europe and emerging Asian economies. In the U.S., the report finds that the decline in capital investment following the 2008 financial crisis has resulted in a $4,500 lower per-capita GDP in 2022 than it would have if pre-crisis trends had continued. Rapid advances in manufacturing technology, especially for electronics, petered out in the same time period, subtracting another $5,000 from per-capita GDP. "Digitization was much discussed as the main candidate to rev up productivity again, but its impact failed to spread beyond" the tech sector, the authors write. The authors are optimistic that a confluence of factors will make the years ahead different. The rise in global interest rates and inflation are evidence of stronger global demand. Many countries are experiencing labor shortages that may incentivize more productivity-enhancing investment. And artificial intelligence and related technologies create big opportunities. "Inflationary pressure and rising interest rates could be signs that we are leaving behind secular stagnation and entering an era of higher demand and investment," the report finds. "In corporate boardrooms around the world right now, there's a tremendous amount of conversation associated with [generative] AI, and I think there's a broad acknowledgment that this could very much transform productivity at the company level," Olivia White, a McKinsey senior partner and co-author of the report, tells Axios. "Another thing that's happening right now is the conversation about labor. Labor markets in all advanced economies, and the U.S. is really sort of top of the heap, are very, very tight right now. So there's a lot of conversation around what do we do to make the people that we have as productive as they can be?" Read more of this story at Slashdot.
