41 p, 433.1 KB On obvious strategy-proofness and single-peakedness / Arribillaga, R. Pablo (Instituto de Matemática Aplicada San Luis (Argentina)) ; Massó, Jordi (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Neme, Alejandro (Instituto de Matemática Aplicada San Luis (Argentina))
We characterize the set of all obviously strategy-proof and onto social choice functions on the domain of single-peaked preferences. Since obvious strategy-proofness implies strategy-proofness, and the set of strategy-proof and onto social choice functions on this domain coincides with the class of generalized median voter schemes, we focus on this class. [...]

Preference restrictions for simple and strategy-proof rules : Local and weakly single-peaked domains / Bonifacio, Agustín G. (Instituto de Matemática Aplicada San Luis (Argentina)) ; Massó, Jordi (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Neme, Pablo (Instituto de Matemática Aplicada San Luis (Argentina))
We show that if a rule is strategy-proof, unanimous, anonymous and tops-only, then the preferences in its domain have to be local and weakly single-peaked, relative to a family of partial orders obtained from the rule by confronting at most three alternatives with distinct levels of support. [...]

We study social choice rules defined on the domain of semilattice single-peaked preferences. Semilattice single-peakedness has been identified as the condition that a set of preferences must satisfy so that the set can be the domain of a strategy-proof, tops-only, anonymous and unanimous rule.

31 p, 377.9 KB Individually rational rules for the division problem when the number of units to be allotted is endogenous / Bergantiños, Gustavo (Universidade de Vigo) ; Massó, Jordi (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Neme, Alejandro (Instituto de Matemática Aplicada San Luis (Argentina))
We study individually rational rules to be used toallot, among a group of agents, a perfectly divisiblegood that is freely available only in whole units. Arule is individually rational if, at each preferenceprofile, each agent finds that her allotment is at leastas good as any whole unit of the good. [...]

Departament d'Economia i d'Història Econòmica) ; Neme, Alejandro (Universidad Nacional de San Luis (Argentina))
For division problems with single-peaked preferences, we show that all sequential allotment rules, a large subfamily of strategy-proof and efficient rules, are also obviously strategy-proof. Although obvious strategy-proofness is in general more restrictive than strategy-proofness, this is not the case in this setting.

42 p, 422.0 KB On Strategy-proofness and the Salience of Single-peakedness / Catterji, Shurojit (Singapore Management University) ; Massó, Jordi (Universitat Autònoma de Barcelona)
We consider strategy-proof rules operating on a rich domain of preference profiles. We show that if the rule satisfies in addition tops-onlyness, anonymity and unanimity, then the preferences in the domain have to satisfy a variant of single-peakedness (referred to as semilattice single-peakedness).

40 p, 432.7 KB Comparing generalized median voter schemes according to their manipulability / Arribillaga, R. Pablo (Universidad Nacional de San Luis) ; Massó, Jordi (Universitat Autònoma de Barcelona)
We propose a simple criterion to compare generalized median voter schemes according to their manipulability. We identify three necessary and sufficient conditions for the comparability of two generalized median voter schemes in terms of their vulnerability to manipulation. [...]

55 p, 354.5 KB La moderna teoria de l'elecció social : de la impossibilitat a la possibilitat / Massó, Jordi (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica)
Es presenten els dos teoremes d'impossibilitat més importants de la moderna teoria de l'elecció social: el teorema d'Arrow per a funcions de benestar social no dictatorials que satisfan el principi de Pareto i la propietat de la independència d'alternatives irrellevants, i el teorema de Gibbard-Satterthwaite per a funcions d'elecció social no trivials i no manipulables. [...]
We present the two most important impossibility theorems of the modern social choice theory: Arrow's theorem for social welfare functions satisfying the Pareto principle and the independence of irrelevant alternatives property, and Gibbard-Satterthwaite's theorem for non-trivial and strategy-proof social choice functions. [...]

19 p, 213.5 KB Bribe-proof rules in the division problem / Massó, Jordi (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Neme, Alejandro (Universidad Nacional de San Luis (Argentina))
The division problem consists of allocating an amount of a perfectly divisible good among a group of n agents with single-peaked preferences. A rule maps preference profiles into n shares of the amount to be allocated. [...]

The division problem consists of allocating an amount M of a perfectly divisible good among a group of n agents. Sprumont (1991) showed that if agents have single-peaked preferences over their shares, the uniform rule is the unique strategy-proof, efficient, and anonymous rule. [...]

44 p, 565.3 KB Restricted environments and incentive compatibility in interdependent values models / Barberà, Salvador 1946- (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Berga, Dolors (Universitat de Girona) ; Moreno, Bernardo (Campus de El Ejido) ; Universitat Autònoma de Barcelona. Consorci Markets, Organizacions and Votes in Economics (MOVE)
We study mechanisms that operate in interdependent values environments. We show that when defined on knit and strict environments, only constant mechanisms can be ex post incentive compatible. Knitness is also necessary for this result to hold for mechanisms with two alternatives in the range. [...]

For the division problem with single-peaked preferences (Sprumont, 1991) we show that all sequential allotment rules, identifed by Barberà, Jackson and Neme (1997) as the class of strategy-proof, e¢ cient and replacement monotonic rules, are also obviously strategy-proof. [...]
