Estimating Lorenz and concentration curves

Ben Jann

Stata Journal, 2016, vol. 16, issue 4, 837-866

Abstract: Lorenz and concentration curves are widely used tools in inequality research. In this article, I present a new command, lorenz, that estimates Lorenz and concentration curves from individual-level data and, optionally, displays the results in a graph. The lorenz command supports relative, generalized, absolute, unnormalized, custom-normalized Lorenz, and concentration curves. It also pro- vides tools for computing contrasts between different subpopulations or outcome variables. lorenz fully supports variance estimation for complex samples. Copyright 2016 by StataCorp LP.
