Homotheticity, duality and efficiency measures

As a result of the duality of cost and distance functions the efficiency of cost-minimizing behaviour can be compared to shadow-prizing behaviour, and conversely. In this framework we outline the form that dual efficiency measures, Muro (1982), Muro and Vera (1983), adopt for homothetic and linearly homogeneous technologies. To illustrate the subject we provide a numerical example for a technology described by a translog cost function.
