The Cobb-Douglas production function was
proposed by Knut Wicksell (1851›1926), and tested
against statistical evidence by Charles Cobb and Paul
Douglas during the period from 1900 to 1928. Just
and Pope (1979) employed a Cobb-Douglas production
form and estimated the standard deviation of the
output. Doll and Orazem (1984) also applied the
Cobb-Douglas production function and suggested
independent variables, such as land, labor, and
capital.
