Abstract

DEA measures efficiency by means of a mere score. This is clearly useful, but there is a need to look further away into the context in which efficiency is achieved. It is argued that Scaling techniques provide a framework for the interpretation of DEA efficiency scores. A methodology is porposed and illustrated by means of a case study: the dot com business. This methodology has the advantage of visualising the main characteristics of the situation under investigation, and revealing aspects that would otherwise have remained hidden. It is shown that DEA model selection can greatly benefit from its inclusion in a scaling framework. It is also shown how the mehtodology proposed can highlight various strategic behaviours that firms follow in the path to efficiency.
