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

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...

The paper applies a multidimensional and comparative approach to the assessment of wellbeing and deprivation among a panel of older people in Brazil and South Africa. It develops and justifies a counting approach to rank order wellbeing and deprivation distributions. An application of this...

An income inequality measure satisfies the Pigou-Dalton transfer principle if progressive transfers decrease income inequality. When transfers cause transaction costs, one can trace out the maximum leakage such that the transfer pays at the margin. An income inequality measure is leaky-bucket...

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...

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...
