# Cobb Douglas Production: Identification issues for technical change

(Asked by: username_0 on 2022-01-10)

It's well know that under a Cobb Douglas production function, capital and labor augmenting technical progress cannot be individually identified. Accordingly, people usually assume Hicks or Harrod neutrality.

But does anyone know if there is a single academic source paper that proved or pointed out this identification issue under Cobb Douglas.
