A balanced panel of 10 observational units (firms) from 1935 to 1954
A data frame containing :
value of the firm
stock of plant and equipment
total number of observations : 200
observation : production units
country : United States
The Grunfeld data as provided in package
plm is the
same data as used in Baltagi (2001), see Examples below.
Various versions of the Grunfeld data circulate online. Also, various text books (and also varying among editions) and papers use different subsets of the original Grunfeld data, some of which contain errors in a few data points compared to the original data used by Grunfeld (1958) in his PhD thesis. See Kleiber/Zeileis (2010) and its accompanying website for a comparison of various Grunfeld data sets in use.
