In a bankruptcy situation, not all claimants are affected in the same way. In particular, some depositors may enter into a situation of personal bankruptcy if they lose part of their investments. Events of this kind may lead to a social catastrophe. We propose discrimination among the claimants as a possible solution. A fact considered in the American bankruptcy law (among others) that establishes some discrimination on the claimants, or the Santander Bank that in the Madoff’s case reimbursed only the deposits to its particular customers. Moreover, the necessity of discriminating has already been mentioned in different contexts by Young (1988), Bossert (1995), Thomson (2003) and Pulido et al. (2002, 2007), for instance. In this paper, we take a bankruptcy solution as the reference point. Given this initial allocation, we make transfers from richer to poorer with the purpose of distributing not only the personal incurred losses as evenly as possible but also the transfers in a progressive way. The agents are divided into two groups depending on their personal monetary value (wealth, net-income, GDP or any other characteristic). Then, we impose a set of Axioms that bound the maximal transfer that each net-contributor can make and each net-receiver can obtain. Finally, we define a value discriminant solution, and we characterize it by means of the Lorenz criterion. Endogenous convex combinations between solutions are also considered.

This paper studies the limits of discrete time repeated games with public monitoring. We solve and characterize the Abreu, Milgrom and Pearce (1991) problem. We found that for the "bad" ("good") news model the lower (higher) magnitude events suggest cooperation, i.e., zero punishment probability, while the highrt (lower) magnitude events suggest defection, i.e., punishment with probability one. Public correlation is used to connect these two sets of signals and to make the enforceability to bind. The dynamic and limit behavior of the punishment probabilities for variations in ... (the discount rate) and ... (the time interval) are characterized, as well as the limit payo¤s for all these scenarios (We also introduce uncertainty in the time domain). The obtained ... limits are to the best of my knowledge, new. The obtained ... limits coincide with Fudenberg and Levine (2007) and Fudenberg and Olszewski (2011), with the exception that we clearly state the precise informational conditions that cause the limit to converge from above, to converge from below or to degenerate.

Un any després de la segona volta de les eleccions presidencials, i a pocs dies de les eleccions legislatives (11 de desembre de 2011), la Costa d’Ivori es troba en un moment especialment important. Després d’intensos enfrontaments armats, el país sembla estar passant cap a una nova etapa de la seva història. Per aquest motiu, ara és un bon moment per establir una retrospectiva crítica de les causes de la crisi postelectoral que, a la vegada, serveixi per construir un escenari per a una construcció pacífica de l’estat. En coherència, aquest policy paper fa una sèrie de recomanacions a curt, mig i llarg termini i pensades a partir d’una premissa: construir la pau i el desenvolupament depèn exclusivament de decisions nacionals, ivorianes, però les responsabilitats i deures són, en alguns casos, compartits per actors nacionals i internacionals. Hom continua així el compromís de l’ICIP amb la construcció de la pau a la Costa d’Ivori.

Taking as an example three study cases in the Costa Brava area, this paper examines the social perceptionof floods through surveys, interviews and Focus Group sessions. Perception is then related to vulnerability, flood management, and citizen’s preferences regarding alternatives to curb flood losses in the future. The study concludes that flood awareness and the willingness to take actions regarding this hazard are clearly related to the degree of social involvement with the affairs of the local community. Furthermore, participatory settings such as Focus Group sessions appear to enable a better environment for assessing and implementing flood management options that attempt to modify human activities rather than modify natural processes as has been frequently the case in the past

Treball sobre la percepció que tenen els turistes dels principals factors que fan possible la seva estada al lloc de destinació. Es pretén saber com és la percepció que tenen quan se’ls acaben les vacances i observar si tenen intenció de tornar a visitar la destinació, en aquest cas la Costa Brava, per poder relacionar les seves opinions amb la intencionalitat

In this paper we relax the Colonel Blotto game assumption that for a given battle the player who allocates the higher measure of resources wins that battle. We assume that for a given battle, the Colonel who allocates the higher measure of resources is more likely to win that battle. We have a simpler model for which we are able to compute all Nash equilibria in pure strategies for any valuations pro le that players might have. Something that is not possible for the original Blotto game. JEL: C72, D74, H56. KEYWORDS: Colonel Blotto game; lottery contest function.

Is it important to negotiate on proportions rather than on numbers? To answer this question, we analyze the behavior of well-known bargaining solutions and the claims rules they induce when they are applied to a "proportionally transformed" bargaining set SP -so-called bargaining-in-proportions set. The idea of applying bargaining solutions to claims problems was already developed in Dagan and Volij (1993). They apply the bargaining solutions over a bargaining set that is the one de ned by the claims and the endowment. A comparison among our results and theirs is provided. Keywords: Bargaining problem, Claims problem, Proportional, Constrained Equal Awards, Constrained Equal Losses, Nash bargaining solution. JEL classi fication: C71, D63, D71.

“El coneixement condueix a la unitat, com la ignorància a la diversitat” Ramakrishna.Fins a quin punt les nostres opinions estan realment ben fonamentades? És la diversitat d’opinió, fruit de la ignorància col·lectiva?Tants punts a tractar sobre la Monarquia o la República, i tan difícils cada un d’ells. En aquest cas, pretenem saber si hi ha o no grans diferències econòmiques entre un sistema i altre, donant un repàs als conceptes i magnituds importants per entendre bé el significat de les dades resultants.Si bé pensàvem que seria difícil arribar a una conclusió clara, i ens sorprèn haver-ho aconseguit, més ens sorprèn el fet d’haver-nos adonat, durant la realització de la investigació, de la carència d’informació que tenim. I no només els ciutadans, sinó els propis governs sobre les seves pròpies dades i sobre el que reflecteixen les mateixes. Conceptes entremesclats, dades poc clares, diferències en les informacions dins llocs oficials d’un mateix país... La República és més cara. Ho sabien? Però...ara que ho saben...és aquest un resultat que podria variar les seves preferències? O necessiten saber més?Tots tenim dret a opinar sobre aquest tema, a triar el que ens agrada més,però, com bé diu Ramakrishna, el resultat de la diversitat d’opinions sobre eltema és, probablement, conseqüència de la poca informació que tenim sobre laglobalitat de factors que influencien en la execució d’una d’aquestes formes d’estat.

O presente trabalho científico enquadra-se no âmbito da elaboração de uma investigação a ser apresentada ao Instituto Superior da Educação (ISE), como requisito à obtenção do grau de licenciatura do Curso de Gestão e Planeamento da Educação, na vertente Gestão e Direcção Escolar. De entre os mais diversos temas, o que mais me despertou a atenção foi, a participação dos pais e encarregados de educação, na gestão escolar, dado que na escola, onde realizei o meu estágio, muito se falava da falta de engajamento ou de participação dos pais na gestão escolar, e da necessidade de participação destes na organização e gestão da escola, como condição indispensável para o processo de desenvolvimento e melhoria da qualidade da educação.
