An Assessment of CES and Cobb-Douglas Production Functions: Working Paper 2008-05
This paper surveys the empirical and theoretical literature on macroeconomic production functions and assesses whether the constant elasticity of substitution (CES) or the Cobb-Douglas specification is more appropriate for use in the CBO’s macroeconomic forecasts. The Cobb-Douglas’s major strengths are its ease of use and its seemingly good empirical fit across many data sets. Unfortunately, the Cobb-Douglas still fits the data well in cases where some of its fundamental assumptions are violated. This suggests that many empirical tests of the Cobb-Douglas are picking up a statistical artifact
