A queuing-based model for optimal dimension of service firms

Parra-Frutos, Isabel - In: SERIEs - Journal of the Spanish Economic Association 1 (2010) 4, pp. 459-474

This paper examines a stochastic model to determine optimal pricing, waiting time, output, and sizing decisions for service firms which compete on time in an uncertain environment. Sizing decisions concern optimal service capacity and maximum physical waiting room (with a given probability)....

All but one free ride when wealth effects are small

Silvestre, Joaquim - In: SERIEs - Journal of the Spanish Economic Association 3 (2012) 1/2, pp. 201-207

Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common...

A unified approach to strategy-proofness for single-peaked preferences

Weymark, John A. - In: SERIEs - Journal of the Spanish Economic Association 2 (2011) 4, pp. 529-550

This article establishes versions of Moulin's (Public Choice 35:437-455, 1980) characterizations of various classes of strategy-proof social choice functions when the domain consists of all profiles of single-peaked preferences on an arbitrary subset of the real line. Two results are established...

An individual manipulability of positional voting rules

Aleskerov, Fuad; Karabekyan, Daniel; Sanver, M. Remzi; … - In: SERIEs - Journal of the Spanish Economic Association 2 (2011) 4, pp. 431-446

We study a problem of individual manipulation in an impartial culture (IC) framework using computer modeling. We estimate the degree of manipulability of ten positional voting rules in the case of multiple choice for 3 and 4 alternatives.

The political economy of income taxation under asymmetric information: The two-type case

Roemer, John E. - In: SERIEs - Journal of the Spanish Economic Association 3 (2012) 1/2, pp. 181-199

The apparent ubiquity of progressive taxation in advanced democracies has animated research by political economists in the past decade, but little progress has been made in modeling political equilibria over tax policy when labor supply is elastic with respect to taxation. Here, we postulate an...

On the optimal allocation of students when peer effects are at work: tracking vs. mixing

Hidalgo-Hidalgo, Marisa - In: SERIEs - Journal of the Spanish Economic Association 2 (2011) 1, pp. 31-52

The belief that both the behavior and outcomes of students are affected by their peers is important in shaping education policy. I analyze two polar education systems -tracking and mixing- and propose several criteria for their comparison. I find that tracking is the system that maximizes...

Strategy-proof voting rules on a multidimensional policy space for a continuum of voters with elliptic preferences

Peters, Hans; Roy, Souvik; Storcken, Ton - In: SERIEs - Journal of the Spanish Economic Association 2 (2011) 4, pp. 485-496

We consider voting rules on a multidimensional policy space for a continuum of voters with elliptic preferences. Assuming continuity, gamma -strategy-proofnessmeaning that coalitions of size smaller or equal to a small number gamma cannot manipulateand unanimity, we show that such rules are...

Euclidean preferences, option sets and strategyproofness

Bordes, Georges; Laffond, Gilbert; Le Breton, Michel - In: SERIEs - Journal of the Spanish Economic Association 2 (2011) 4, pp. 469-483

In this note, we use the technique of option sets to sort out the implications of coalitional strategyproofness in the spatial setting. We also discuss related issues and open problems.
