We examine the problem of measuring the extent to which students with different income levels attend separate schools. Unless rich and poor attend the same schools in the same proportions, some segregation will exist. Since income is a continuous cardinal variable, however, the rich-poor...

We show that it is possible to incorporate any appropriation technology available to thieves into a Walrasian economy so that in equilibrium more police induces more crime. This perverse effect could arise even if the level of police protection is the socially optimal one

In several economic fields, such as those related to health or education, the individuals’ characteristics are measured by bounded variables. Accordingly, these characteristics may be indistinctly represented by achievements or shortfalls. A difficulty arises when inequality needs to be...

A match is a recursive zero-sum game with three possible outcomes: player 1 wins, player 2 wins or there is a draw. Play proceeds by steps from state to state. In each state players play a "point game" and move to the next state according to transition probabilities jointly determined by their...

It is possible to partially order cities according to the informativeness of neighborhoods about their ethnic groups. It is also possible to partially order cities with two ethnic groups according to them Lorenz criterion. We show that a segregation order satisfies four well-established...

We provide a simple proof of Foster's (1983) characterization of the Theil inequality index.
