This study investigates the water demand of Indian manufacturing plants. It adopts an input distance function approach … and approximates it by a translog form. Duality between cost function and input distance function is exploited to retrieve …

This paper proposes a constrained nonparametric method of estimating an input distance function. A regression function … estimated input distance function are derived, and thus the elasticities measuring input substitutability can be computed from … is estimated via kernel methods without functional form assumptions. To guarantee that the estimated input distance …
