Ñopo, Hugo (2008). An extension of the Blinder-Oaxaca decomposition to a continuum of comparison groups. Economics Letters, Elsevier, vol. 100(2), pages 292-296, August.

This paper proposes an extension of the Blinder-Oaxaca decomposition from two to a continuum of comparison groups. The proposed decomposition is then estimated for racial wage differences in urban Peru, exploiting a novel data set that allows the capturing of different degrees of mestizaje (racial mixtures).
