Everything about Zvi Griliches totally explained
Hirsh Zvi Griliches (
12 September 1930 –
4 November 1999) was an
economist at
Harvard University. He was born in
Kaunas,
Lithuania in an
assimilated Jewish family that spoke
Russian at home. During
World War II he was sent to the
Dachau concentration camp. In 1947 he emigrated to
Palestine, where he served in the pre-state
Israeli army, learned
Hebrew, passed high school equivalence exam, and studied for a year at
Hebrew University. He then moved to the United States, where he earned a B.S. in Agricultural Economics from the
University of California, Berkeley, and then a Ph.D. in Economics at the
University of Chicago.
The works by Zvi Griliches mostly concerned the
economics of
technological change, including
empirical studies of
diffusion of innovations and the role of R & D, patents, and education.
In his classic 1957 Ph.D. dissertation,
Hybrid Corn: An Exploration in the Economics of Technological Change, published as an article in the October 1957 issue of
Econometrica, Griliches demonstrated that the penetration of corn seeds followed the
logistic curve. It was found later through multiple examples by
Edwin Mansfield and other researchers that this is a general rule for
technological change /
diffusion of innovations. The dissertation was one of the first scientific works that treated the development of new technology as an economic phenomenon. Previously, economists had treated it as exogenous.
Most innovations either make production more efficient, or improve the quality of goods. The analysis of measurement of the impact of innovations on economics led Griliches to his fundamental studies of
economic growth,
productivity,
production function,
consumption function, measurements of economic
input and
output,
hedonic prices, and their reflection in
price indices.
Griliches also published important works of
econometrics, including
distributed lags (
time series) and
aggregation. He was particularly interested in the measurements of hidden variables.
Griliches served as the President of the Econometric Society in 1975, and as the President of the American Economic Association in 1993. From 1969 to 1977 he was one of editors of the journal
Econometrica. He served on the
Stigler Commission in 1961 and the
Boskin Commission in 1996, both of which were convened by the
United States Senate to evaluate the measurement of
inflation.
In 1965, Zvi Griliches won the prestigious
John Bates Clark Medal. He was elected to the American Academy of Arts and Sciences in 1965 and to the National Academy of Sciences in 1975. He was also elected Distinguished Fellow of the American Economic Association, Fellow of the Econometric Society, Fellow of the American Statistical Association, Fellow of the American Association for the Advancement of Science, and Fellow of the American Agricultural Economics Association.
The
Zvi Griliches Research Data Center
was established in his memory at the Samuel Neaman Institute for Advanced Studies in Science and Technology in Israel. The
Zvi Griliches Excellence Award was established by the Economics Education and Research Consortium (EERC) in Russia and other former Soviet Union countries.
