As it is known, there is no rule satisfying Additivity in the complete domain of bankruptcy problems. This paper proposes a notion of partial Additivity in this context, to be called m-additivity. We find that m-additivity, together with two quite compelling axioms, anonymity and continuity,...

This paper explores an integrated taxation system. Taking as a premise the proposals by the Carter Commission Report, we find out that proportional tax is the unique system that allows to neutrally integrate the taxable income. This analysis leads to explore new tax rules combining the extreme...

An input-output model with non-constant returns to scale and externalities is presented, and it is shown that in this model the non-substitution theorem is still valid. More precisely, the quantity side of the theorem, i.e. the proposition on efficiency, remains valid, while there can be no...

This paper proposes a notion of partial Additivity in bankruptcy, -Additivity. We show that this property, together with Anonymity and Continuity, identifies the Minimal Overlap rule, introduced by O'Neill (1982).

This paper provides an ‘escape route’ from the efficiency-equity trade-off in the School Choice problem. We achieve our objective by presenting a weak notion of fairness, called τ-fairness, which is always satisfied by some allocation. Then, we propose the adoption of the Student Optimal...

We design a mechanism to allocate indivisible objects that combines procedural and distributive fairness. It associates each allocation problem a family of priorities to be used when determining how agents and objects should be matched. The selection of specific priorities, correlated with...

We explore the problem of distributing a group of indivisible objects, some of which incorporate a primitive assignment of use, or tenancy right. Within this framework we analyze the existence of rules always selecting an ex-ante efficient allocation, conditioned to a preservation of the...

Despite the popularity of auction theoretical thinking, it appears that no one has presented an elementary equilibrium analysis of the complete information first-price sealed-bid auction mechanism when the bidding space has a finite grid. This paper aims to remedy that omission. We show that...
