We estimate capacity when firms produce both desirable and undesirable outputs using a directional distance function model, and a hyperbolic model. We impose different assumptions regarding disposability of undesirable outputs in both models, and vary the direction of vectors in the directional...

In this note we extend the standard DEA paradigm to address the question of how one can price DMUs (decision-making units). To do this we use an adjoint transformation to the technology generated by these DMUs which links to traditional linear programming theory of the firm and is similar to...
