We consider a monopolist producer of information goods that may be subject to unauthorized copying. The key feature of our model is that we allow consumers to have ethical concerns based on equity theory that may reduce their utility of such a copy. We derive the formulas describing demand for...

We present a class of decomposable inequality indices for ordinal data (e.g. self-reported health survey). It is characterized by well-known inequality axioms (e.g. scale invariance) and a decomposability axiom which states that an index can be represented as a function of inequality values in...

In this paper we present the results of multidimensional poverty analysis in five Polish gminas: Zgierz, Gliwice, Gostyń, Małogoszcz and Manowo. Income and educational attainment are two dimensions of well-being we consider. The analysis is based on the concept of stochastic dominance known in...

Decomposability of multidimensional inequality indices by attributes is considered a highly desired property. Naga and Geoffard (2006) provided for it in case of three bivariate indices. To this end, they introduced the notion of a copula function into inequality measurement theory which, as a...
