Yehuda Grunfeld

Yehuda Grunfeld (born Grünfeld; March 11, 1930 – July 16, 1960) was an Israeli economist. He created and used a well-known data set on firms' investment, which is one of the most widely used data sets in econometrics.

There are various versions/subsets of the data set used in economic papers and text books, some of which contain errors at some data points. Numerous variants of the original data sets are compared in Kleiber/Zeileis (2010).

He received his B.A. degree and his M.A. degree at the Hebrew University in 1953 and 1955, respectively. In 1958, he received his Ph.D. at the University of Chicago. His career ended abruptly when he drowned on July 16, 1960 at the age of 30.
