The Two-Dimensional Projection

Abstract

Much of the conceptual understanding of DEA models of technology and their corresponding efficiency measures can be understood by examining a two-dimensional projection embedded in the technology. A two-dimensional projection is an example of a well-behaved single-input, single-output technology. We shall show how to compute this projection, thereby permitting a graphical determination of the input, output, and joint input-output efficiency measures from a single graph in the plane.
