This note provides a useful property of the Allen-Uzawa partials for the translog cost function. It also suggests how the main results extend to any functional form with certain properties. The curvature of the Allen-Uzawa matrix is the same as the curvature of the Hessian matrix. Intuitively...

This study examined whether the cost efficiency measures were invariant to the choice of parametric and nonparametric methods for a sample of 183 wheat farms. In the deterministic nonparametric method, the economic, scale and overall efficiency results were invariant to the dimensionality. Only...
