Surplus measures and luenberger Hicks–Moorsteen productivity indicator
Résumé
This paper extends to production theory some notions of compensated and equivalent variation analyzed in Luenberger (Econ Theory 7:445-462, 1996) in a consumer context. Along this line the Luenberger-Hicks-Moorsteen productivity indicator introduced in Briec and Kerstens (Econ Theory 23:925-939, 2004) is derived from these concepts for multi-output production technologies. The dual properties of this productivity indicator are analyzed and an aggregate indicator is introduced inspired from the resource function proposed in Luenberger (1996). A connection to a suitable Slutsky matrix is established.
