On the problem of the purchasing power of money by A. A. Konüs and S. S. Byushgens: translation and commentary

Abstract

AbstractIn 1939, Econometrica published an English translation of Konüs (1924). Since then, Konüs (1924 [1939]) has become a classic work on the theory of the cost of living index, inspiring many other studies in the field. On the other hand, very few scholars have had the opportunity to read another, equally important, work by Konüs (co-authored with Byushgens) published in 1926 by the same Institute. This other paper of Konüs also pioneered several fundamental concepts and results in economics (including duality theory, the theory of inverse demand functions and the theory of exact index numbers), yet somehow it appears that it has never been translated into English (or any other language). We bridge this gap by offering a translation and a commentary on this important paper.
