Also in 1926, Frisch published an article outlining his view that economics should follow the same path towards theoretical and empirical quantization that other sciences, especially physics, had followed. During the same year, he published his seminal article "Sur un problème d'économie pure" starting the implementation of his own quantization programme. The article offered theoretical axiomatizations which result in a precise specification of both ordinal and cardinal utility, followed by an empirical estimation of the cardinal specification. Frisch also started lecturing a course on production theory, introducing a mathematization of the subject.
