Robert Hall's 1978 paper turned consumption research upside down: if households are forward-looking, today's spending already contains everything they know, so changes in spending should be unpredictable. The video builds that intuition, shows how Hall tested it on US quarterly data from 1948 to 1977, and explains why it became a foundation of the New Keynesian models cited in the 2026 Prize in Economic Sciences.
