Directional output distance functions: endogenous directions based on exogenous normalization constraints

Färe, R.; Grosskopf, S.; Whittaker, G. - In: Journal of Productivity Analysis 40 (2013) 3, pp. 267-269

In response to a question raised by Knox Lovell, we develop a method for estimating directional output distance functions with endogenously determined direction vectors based on exogenous normalization constraints. This is reminiscent of the Russell measure proposed by Färe and Lovell (J Econ...
