In neoclassical models, workers are classified a priori into discrimination groups. We develop a probabilistic model of wage discrimination in which workers need not be classified a priori. Our model is a generalization of the standard framework, whereas Becker's model is an extreme case. A...

Standard wage discrimination models assume that independent observers are able to distinguish a priori which workers are suffering from discrimination. However, this assumption may be inadequate when severe penalties can be imposed on discriminatory employers. Antidiscrimination laws will induce...

Let us assume a revenue- and inequality-neutral flat tax reform shifting from a graduated-rate tax. Is this reform really distributional neutral? Traditionally, there has been a bias toward the inequality analysis, forgetting other relevant aspects of the income distribution. This kind of...

We provide a partial ordering view of horizontal inequity (henceforth HI), based on the Lorenz criterion, associated with different post-tax income distributions and a (bistochastic) nonparametric estimated benchmark distribution. As a consequence, several measures consistent with the Lorenz...

In this article, polarization measurement is presented as a useful tool for characterizing the net transfers of income between individuals caused by a tax reform. The bipolarization measure, which considers just two poles and involves the disappearance of the middle class, may complement...

In this paper we provide a connection between concentration and inequality by showing that the inequality measures consistent with the whole class of Hannah-Kay concentration indices are the general entropy inequality indices. We isolate the inequality component underlying the concentration...
