BOUNDING ESTIMATES OF WAGE DISCRIMINATION

Abstract

The Blinder Oaxaca decomposition method for defining wage differentials (generally referred to as discrimination) from the wage equations of two groups has had a wide degree of application. However, the decomposition measures can very dramatically depending on the definition of the non-discriminatory wage chosen for comparison. This paper uses a form of extreme bounds analysis to define the limits on the measure of discrimination that can be obtained from these decompositions. A simple application is presented to demonstrate the use of the bootstrap to define the distributions of the discrimination measure. © 2004.
