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...

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...

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...

This paper introduces tau-fairness as a compromise solution reconciling Pareto efficiency and equity in School Choice Problems. We show that, by considering a weak notion of equity that we refer to as lambda-equity, it is possible to contribute positively to solve an open debate, originated by...

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...

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...
