I study the effects of a linear tax schedule on educational decisions and welfare in a two period model where the educational decision is discrete and its return is uncertain. I find that a linear tax rate has a positive effect on the number of agents who decide to acquire higher education. This...

The popular support obtained by two parties who propose two qualitatively different tax schernes is analyzed. We show that if the median voter is below the mean, then any progressive proposal always wins over a regressive one, provided it leaves the poorest agent at least as well off as the...

In this paper we study the problem of fair allocation in economies with indivisible goods, dropping the usual restriction that one agent receives at most one indivisible good. We show that most of the results obtained in the literature do not hold when the above mentioned restriction is dropped.

Choice functions on tournaments always select the maximal element (Condorcet winner), provided they exist, but this property does not hold in the more general case of weak tournaments. In this paper we analyze the relationship between the usual choice functions and the set of maximal elements in...

This paper studies convergence and stability properties of Sjöström's (1994) mechanism, under the assumption that boundedly rational players find their way to equilibrium using monotonic learning dynamics and best-reply dynamics. This mechanism implements most social choice functions in...

The literature on vouchers often concludes that a voucher-based system cannot be the outcome of a majority vote. This paper shows that it is possible to propose selective vouchers (of exogenous value) such that the majority of voters are in favour of selective vouchers. As long as the...

We develop a model of team formation in which workers learn about their level of ability. We show that insufficient cooperation may arise as workers learn positively about their own skills. We then build a model for team managers and establish that their objectivity in assessing coworkers'...
