The authors introduce a procedure for transforming any homogeneous technology into a nonhomothetic one. This procedure is particularly useful when applied to a nonseparable two-stage constant elasticity of substitution technology since the number of additional parameters to be estimated is small and since imposing regularity conditions in the estimation of these technologies is straightforward. The authors illustrate the technique by estimating the nonseparable two-stage Leontief constant elasticity of substitution cost function using the familiar Berndt-Wood-Khaled time-series data on U.S. manufacturing output, and compare their results with the familiar (single-stage) translog cost function.
