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...

Reverse auctions are considered a fast and inexpensive price discovery tool to award procurement contracts and it is often desirable to award contracts to more than one supplier. We propose a new procurement procedure that is based on a reverse auction. Shares are allocated endogenously,...

We study the effects of affirmative action through endogenous set-asides. We propose a share auction for dual sourcing in which more intensive affirmative action strengthens the favoured provider. This has the potential to level the playing field and induce more competitive procurement overall....

This paper studies the sequential mechanisms which mimic matching procedures formany-to-one-real-life matching markets. We provide a family of mechanisms implementing thestudent´ optimal allocation in subgame perfect equibrium.

This paper introduces a property over agents' preferences, called Tops Responsiveness Condition. Such a property guarantees that the core in Hedonic Coalition Formation games is not empty. It is also shown that a mechanism exists that selects a stable allocation. It turns out that this...

This paper studies simple hiring procedures for job markets. We show that when agents act strategically only individually rational outcomes should be expected. Moreover, If agents can form unions, thereby gaining the possibility to commit on the decision to be chosen, only stable allocations are...

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...

We analyze (non-deterministic) contests with anonymous contest success functions. There is no restriction on the number of contestants or on their valuations for the prize. We provide intuitive and easily verifiable conditions for the existence of an equilibrium with properties similar to the...
