Distance Functions

Abstract

A distance function is a remarkably simple yet powerful concept. This function underpins nonparametric efficiency analysis, and is also the basis for a nonparametric approach for assessing productivity that we will discuss in Part III. The distance and cost function are linked via two, symmetric identities; knowledge of one function is sufficient to determine the other one.
