Editing Ragnar Frisch (section)

===Early career and further education===
In 1921 Frisch received a fellowship from the university which enabled him to spend three years studying economics and mathematics in [[France]] and [[England]]. After his return to [[Norway]], in 1923, although the family's business was having difficulties, he continued his scientific activity, believing that research, not jewellery, was his real calling.<ref name=Bjerkholt>Olav Bjerkholt (2000), "A turning point in the development of Norwegian economics – the establishment of the University Institute of Economics in 1932". Memorandum No 36/2000, University of Oslo</ref> He published a few papers about [[probability theory]], started teaching at the University of Oslo during 1925 and, in 1926, he obtained the Dr. Philos. degree with a thesis in [[mathematical statistics]].

Also in 1926, Frisch published an article<ref>"Quantitative formulation of the laws of economic theory" (see Selected Publications)</ref> 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 utility|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.

Frisch received a fellowship from the [[Rockefeller Foundation]] to visit the [[United States]] in 1927. There, seeking other economists interested in the new mathematical and statistical approaches to economics, he associated with [[Irving Fisher]], [[Wesley Clair Mitchell]], [[Allyn Young]] and [[Henry Schultz]]. He wrote a paper analyzing the role of [[investment (macroeconomics)|investment]] in explaining [[economic fluctuations]]. Wesley Mitchell, who had just written a book on [[business cycle]]s, popularized Frisch's paper which was introducing new advanced methods.<ref name=Bjerkholt/>
