After the beginning of his apprenticeship, Frisch’s mother feels that the trade would not be satisfactory for him. She insists that he should take up a university study. He chooses economics because at that time, it is the shortest and easiest course of study (which would later change). He passes his university degree in economics in Oslo, 1919.
Frisch receives a fellowship to visit the United States in 1927. There he seeks out other economists interested in the new mathematical and statistical approaches to economics. He writes a paper analyzing the role of investment in explaining economic fluctuations, introducing new advanced methods.
He completes an apprenticeship as a goldsmith, which he finishes in 1920.
Ragnar Frisch is born in Oslo, Norway, as the son of a gold- and silversmith.
Ragnar Frisch shares the 1969 Nobel Prize in Economics with Jan Tinbergen "for having developed and applied dynamic models for the analysis of economic processes". He has founded the discipline of econometrics and has helped introduce econometric modeling to government economic planning and accounting. He has done pioneering work on econometric model building, and has constructed theories for stabilization policy and long-term economic planning.
