What did Robert Hall change about modern macroeconomics?

Comment “Flat Taxes” and we’ll send you an article on a topic Robert Hall has studied and advocated extensively. In Part I of our series on the 2026 Nobel Prize in Economics, we look at Robert Hall, one of 2026’s Nobel laureates in Economics, whose work helped transform how economists think about consumption, expectations, and fiscal stimulus. Building on ideas associated with Milton Friedman and Robert Lucas, Hall found evidence that households smooth consumption over time and respond to expected lifetime resources, not simply current income. Hall also became a prominent advocate of a flat tax designed to simplify taxation and reduce penalties on saving and investment. Stay tuned for Part II, where we’ll look at Michael Woodford’s contributions to modern macroeconomics.
