Norwegian economist. Born in Skedsmo. Graduated from the University of Oslo in 1933, he became an assistant to R. A. K. Frisch at the university's Institute of Economics, but left for the United States in 1939. As the Second World War intensified, he stayed in the United States, earned his doctorate at Harvard University, and took up a teaching position at the University of Chicago. Returning to Norway in 1947, he became a professor at the University of Oslo in 1948, and became a professor emeritus in 1979. Under the tutelage of Frisch, the founder of econometrics, Haubermo constructed an econometric model that applied probability theory. He believed that no matter how precise the model, it would be impossible to accurately represent real economic development because of the complex factors involved, and improved the accuracy of econometric models by introducing the statistical concept of multicollinearity (the probability that several causal variables in a relationship are actually linked in some way and rise or fall together) into econometrics. He is also known for his research on the development of domestic investment ( A Study in the Theory of Investment , published in 1960). Haubermo was awarded the Nobel Prize in Economic Sciences in 1989 for "establishing a methodological foundation for econometrics through a probabilistic approach."

ノルウェーの経済学者。スケトスモに生まれる。1933年にオスロ大学を卒業、同大学経済研究所でR・A・K・フリッシュの助手となったが、1939年にアメリカに渡った。第二次世界大戦の戦火が激しくなったため、アメリカに滞在し、ハーバード大学で博士号を取得、シカゴ大学で教職についた。1947年にノルウェーに戻り、1948年オスロ大学教授に就任、1979年に名誉教授となった。 ホーベルモは、計量経済学を創始したフリッシュの教えを受け、確率論を応用した計量経済モデルを構築した。どのような精密なモデルでも現実の経済発展は複雑な要因がからんでいるため正確なものを表すことはできないとし、統計学の多重共線性(ある関係における原因変数のいくつかが実際になんらかの方法で連係し、ともに上昇したり下降したりする確率)を計量経済学に導入することにより、計量経済モデルの精度を高めた。そのほか、国内の投資の発展に関する研究(1960年発表の『A Study in the Theory of Investment』)でも知られる。ホーベルモは1989年にノーベル経済学賞を受賞したが、その受賞理由は「計量経済学における確率論的アプローチによる方法論的基礎の確立」であった。 [金子邦彦] 『山田勇編・訳『計量経済学の確率的接近法』(1955・岩波書店)』 [参照項目] | | | | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
