Markos John Mamalakis (Greek: Μάρκος Μαμαλάκης; 30 October 1932 – 10 July 2024) was a Greek economist who specialised in development economics, particularly in Latin America.
Born in Salonika, he graduated from the Experimental High School of the Aristotle University of Thessaloniki in 1950, then attended the Law School of the University and received a B.A.
(1959), and Ph.D. (1962) with a dissertation entitled Inflation and Growth: An Asset Preference Analysis.
He has published widely on macroeconomics in developing economies and welfare and sector effects.
He argued for the fruitfulness of a mesoeconomic analysis of social interactions, rather than a strictly microeconomic or macroeconomic approach.
