Robert Mundell
Canadian Nobel laureate (1932–2020) associated with optimal currency areas, open-economy monetarist ideas, and intellectual roots of supply-side tax debates.
Mundell modeled how countries with different shocks and labor mobility might (or might not) share a currency advantageously—frameworks later applied to the euro. His work on policy mix under fixed and floating rates shaped textbook macro.
He also advised on low-tax, stable-money narratives embraced politically in the 1980s—linking technical tradeoffs to supply-side branding.

Mundell’s policy-mix insights and optimal-currency-area logic sit behind modern arguments about independent currencies versus pegs—context for exchange-rate and Bretton Woods material without requiring every reader to trace the algebra.
