Bayesian approach to disentangling technical and environmental productivity

Malikov, Emir; Kumbhakar, Subal; Tsionas, Efthymios G. - In: Econometrics : open access journal 3 (2015) 2, pp. 443-465

This paper models the firm's production process as a system of simultaneous technologies for desirable and undesirable outputs. Desirable outputs are produced by transforming inputs via the conventional transformation function, whereas (consistent with the material balance condition) undesirable...
