In the two decades before World War I, Irving Fisher and his French contemporary Adolphe Landry presented and extended Boehm-Bawerk’s theory capital and interest, although both of them criticized Boehm-Bawerk’s concept of an average period of production. They analyzed each other’s work on interest theory in books reviews and books. They both attempted to construct an operationally meaninful version of the quantity theory of money, with Fisher building explicitly on early studies by Landry and Pierre des Essars in France and by Edwin Kemmerer and David Kinley in the US.
