Query: The Allen--Uzawa elasticity of substitution for nonhomogeneous
  production functions   This note proves that the representation of the Allen elasticity of
substitution obtained by Uzawa for linear homogeneous functions holds true for
nonhomogeneous functions. It is shown that the criticism of the Allen-Uzawa
elasticity of substitution in the works of Blackorby, Primont, Russell is based
on an incorrect example.
