Hassett: US Productivity Growth Currently Seen Around 2.5%

The significance here is less the productivity figure itself than its use as an official baseline: it anchors the administration's growth math and, by extension, how it frames fiscal and policy headroom. Productivity is the variable that determines whether faster GDP growth is disinflationary or simply demand outpacing supply, so the pairing of these two numbers is what gives the item weight. The open question is whether the productivity assumption holds up in subsequent data, since that is what would validate or undermine the growth baseline.
