Proposed by the American economist Kenneth Arrow (1921- ), Hollis Chenery (1918- ), BAGICHA S. MINHAS, and Robert Solow (1924- ), CES production function is also known as the constant elasticity of substitution function.
This is a linearly homogenous production function with a constant elasticity of input substitution, which takes on forms other than unity.
It replaced the Cobb-Douglas Production Function model which looked at physical output as a product of labor and capital inputs.
The equation for the CES production function model is:
Q = A(ak – b-b + (1 – c)L – b-b) – 1/b
where Q is output, K capital and L labor and a, b, c are constants.
