Abstract(s)

This paper calls attention to the implications of using value data in efficiency measurement through Data Envelopment Analysis (DEA). The main contributions are twofold: (i) it provides a reconciliation of the previous literature on analysing issues of quantity and value data in efficiency measurement, (ii) it provides some guidelines on what to do, when these issues arise in a data set.
