• TITLE: A Note on Separability of the Profit Function

  AUTHORS: Rolf Färe, Giannis Karagiannis

  KEYWORDS: Separability, Profit Function, Directional Distance Function, Graph Translation Homotheticity, Simultaneous Input-and-Output Translation Homotheticity

  ABSTRACT: Based on the concept of translation elasticity we restate in this note theFare and Grosskopf’s [1] conditions for additive separability of the profit function. We show that for the profit function to be additively separable, the technology must satisfy both simultaneous input-and-output translation homotheticity and graph translation homotheticity.
