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...

This paper emphasizes the properties of a family of inequality measures which extends the Atkinson indices and is axiomatically characterized by a multiplicative decomposition property where the withingroup component is a generalized weighted mean with weights summing exactly to 1. This family...
