- real-valued ordinal utility functions of individuals (illustrated by indifference-curve maps) for commodities

Bergson was chief of the Russian Economic subdivision of the Office of Strategic Services during World War II. After the war he taught at Columbia University and Harvard University. He was elected a Fellow of the American Academy of Arts and Sciences in 1963. From 1964, he was director of the Harvard Russian Research Center and became chairman of the Social Sciences Advisory Board of the U.S. Arms Control and Disarmament Agency.
His main contribution to the study of the Soviet Union was the development and implementation of a method for the calculation of national output and economic growth in the absence of market valuation. The calculation is based on factor price.
