In 1950, Nash's seminal paper introduced the axiomatic approach to the analysis of bargaining situations. Since then, many bargaining solutions have appeared and been axiomatically analyzed. The fact that agents, when face a bargaining problem, can come up with different solution concepts (that...

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...

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 old solution for bankruptcy problems, described by Ibn Ezra in the XII century. Particularly, we introduce a new way of extending the Ibn Ezra’s proposal, the Generalized Ibn Ezra solution, by imposing that the general distribution principle from which it is inspired...

type="main" xml:lang="en" <p>This paper studies a way of introducing affirmative action in the school choice problem to implement integration policies. The paper proposes the use of a natural two-step mechanism. The (equitable) first step is introduced as an adaptation of the deferred-acceptance...</p>

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...
