Robert Alexander Mundell, CC (October 24, 1932 – April 4, 2021) was a pioneer of international macroeconomics and probably the most prominent Canadian economist. He was a Professor of Economics at Columbia University and the Chinese University of Hong Kong.
He received the Nobel Memorial Prize in Economic Sciences in 1999 “for his analysis of monetary and fiscal policy under different exchange rate regimes and his analysis of optimum currency areas.”.
His adaptation of the keynesian model to allow for perfect capital mobility in the early 1960s is known as the Mundell–Fleming model and still serves as the basis for the analysis of short run stabilization policy in open economies.
