Retired Economics Professor Robert Summers, who taught here at the University of Pennsylvania from 1960 to 1991, passed away on April 17.
In 1998 he was named an American Economics Association Distinguished Fellow for his path-breaking work on the measurement of consistent economic aggregates and prices across nations and over time. This project, produced in collaboration with fellow economists and faculty members Alan Heston and the late Irving Kravis, developed real product comparisons and estimated purchasing-power parities for an expanding number of countries.
