In the problem of locating multiple public facilities studied by Barbera and Bevia [2, 3], we offer simple necessary and sufficient conditions for efficiency, decentralizability of efficient decisions in a game of community division and local public goods provision, and a constructive algorithm...

We establish the precise connections between progressive taxation andinequality reduction, in a setting where the level of tax revenue to be raised isendogenously fixed and tax schemes are balanced. We show that, in contrastwith the traditional literature on taxation, the equivalence between...

We investigate the implications and logical relations between progressivity (a principle of distributive justice) and merging-proofness (a strategic principle) in taxation.

Robert Nozick allegedly introduced his liberal theory of private ownership as an objection to theories of end-state justice. Nevertheless, we show that, in a stylized framework for the allocation of goods in joint ventures, both approaches can be seen as complementary. More precisely, in such a...
