BackgroundDespite the intrinsic value of scientific disciplines, such as Economics, it is appropriate to gauge the impact of its applications on social welfare, or at least Health Economics (HE) case- its influence on health policy and management.MethodsThe three relevant features of knowledge (production, diffusion and application) are analyzed, more from an emic perspective the one used in Anthropology relying on the experience of the members of a culture- than from an etic approach seated on material descriptions and dubious statistics.ResultsThe soundness of the principles and results of HE depends on its disciplinary foundations,whereas its relevance than does not imply translation into practice- is more linked with the problems studied. Important contributions from Economics to the health sphere are recorded.HE in Spain ranks seventh in the world despite the relatively minor HE contents of its clinical and health services research journals.HE has in Spain more presence than influence, having failed to impregnate sufficiently thedaily events.ConclusionsHE knowledge required by a politician, a health manager or a clinician is rather limited; the main impact of HE could be to develop their intuition and awareness.

More and more academic journals adopt an open-access policy, by which articlesare accessible free of charge, while publication costs are recovered through authorfees. We study the consequences of this open access policy on a journal s qualitystandard. If the journal s objective was to maximize social welfare, open accesswould be optimal as long as the positive externalities generated by its diffusionexceed the marginal cost of distribution. However, we show that if an open accessjournal has a different objective (such as maximizing readers payoffs, the impactof the journal or its profit), it tends to choose a quality standard below the sociallyefficient level.

In this paper we study the relationship between labor market institutions and monetary policy. We use a simple macroeconomic framework to show how optimal monetary policy rules depend on labor institutions (labor adjustment costs, and nominal and real wage rigitidy) and social preferences regarding inflation, employment, and real wages. We also calibrate our model tocompute how the change in social welfare brought about by giving up monetary policy as a result of joining the Economic and Monetary Union (EMU) depends on institutions and preferences. We then use the calibrated model to analyze how EMU affects the incentives for labor market reform, both for reformsthat increase the economy's adjustment potential and for those that affect the long-run unemployment rate.

This PhD dissertation deals with the question of evaluating social welfare and public policy making through the works of William Stanley Jevons (1835-1882) and Léon Walras (1834-1910), two economists who lived in the 19th century. These authors, well-known for their analyses on pure economics, were also deeply interested in the social problems of their time and proposed solutions to remedy them. In accordance with utilitarianism, Jevons was convinced that the reforms implemented by public authorities should improve social welfare (viewed as dependant on individual utilities). As for Walras, he defined a justice criterion based on a particular definition of natural law, and the reforms he proposed had the objective of restoring the rights following from this definition. We have drawn two principal conclusions from our work. First, the analyses of Jevons and Walras, who are often considered marginalise, are different not only in pure economics (as suggested by Jaffé in the seventies), but also from the point of view of welfare economics (defined as a science dealing with the evaluation of different social states). Secondly, these authors propose two different ways of justifying social reforms which have similarities with modern theory even though neither Jevons nor Walras are considered pioneers of welfare economics or public economics. Based on these two conclusions, we claim that studying these authors' theories might be of interest for the evaluation of public projects by the economists of today. Not only were their problems similar to ours, but also the original ideas present in their analyses may lead to the refinement of modern methods.Résumé en françaisCette these de doctorat porte sur les manières dont deux économistes du XIXe siècle, William Stanley Jevons (1835-1882) et Léon Walras (1834-1910), abordent la question du bien- etre collectif et la prise de décision publique. Connus principalement pour leurs travaux en économie pure, ces auteurs s'intéressent également à la question sociale et proposent des solutions pour y remédier. Jevons, conformément à son adhésion à la tradition utilitariste, estime que les interventions des autorités publiques doivent avoir pour objectif l'amélioration du bien- être collectif. Quant à Walras, il adopte un critère de justice qui relève du « droit naturel » et les propositions sociales qu'il préconise sont justifiées sur la base de leur conformité avec ce dernier. A l'issue du travail effectué dans le cadre de cette thèse, nous avons abouti à deux résultats principaux : (1) Les analyses de Jevons et Walras, deux économistes qui sont souvent considérés comme des « marginalistes » diffèrent fondamentalement non seulement dans leur analyse de l'économie pure, comme Jaffé le soulignait (1976), mais également en termes d'économie du bien-être (comprise comme une science ayant pour objectif l'évaluation des différents états sociaux). (2) Il existe deux voies originales pour justifier les réformes sociales dans les oeuvres de Jevons et Walras qui partagent des similarités importantes avec les théories modernes bien que ces auteurs ne fassent pas partie des jalons généralement retenus de l'histoire de l'économie du bien-être et de l'économie publique. Ces deux résultats nous conduisent à avancer que l'étude des approches de Jevons et de Walras peut contribuer à la formulation de nouvelles solutions à des problèmes rencontrés dans l'évaluation des différentes politiques publiques, car non seulement les préoccupations de ces auteurs était similaires aux nôtres, mais vu les éléments originaux que leurs propositions comportent, elles peuvent permettre de nuancer certaines aspects des méthodes modernes.

The Iowa Award represents the state’s highest citizen award. The Iowa Centennial Memorial Foundation, established in 1948 by Governor Robert D. Blue and the Iowa General Assembly, created the award. The foundation wished “to encourage and recognize the outstanding service of Iowans in the fields of science, medicine, law, religion, social welfare, education, agriculture, industry, government, and other public service” and to recognize the “merit of their accomplishments in Iowa and throughout the United States.”

We study the determinants of political myopia in a rational model of electoral accountability where the key elements are informational frictions and uncertainty. We build aframework where political ability is ex-ante unknown and policy choices are not perfectlyobservable. On the one hand, elections improve accountability and allow to keep well-performing incumbents. On the other, politicians invest too little in costly policies withfuture returns in an attempt to signal high ability and increase their reelection probability.Contrary to the conventional wisdom, uncertainty reduces political myopia and may, undersome conditions, increase social welfare. We use the model to study how political rewardscan be set so as to maximise social welfare and the desirability of imposing a one-term limitto governments. The predictions of our theory are consistent with a number of stylised factsand with a new empirical observation documented in this paper: aggregate uncertainty, measured by economic volatility, is associated to better fiscal discipline in a panel of 20 OECDcountries.

Dins del 7è Programa marc de la Unió Europea, s'ha endegat un estudi, que va del 2008 al 2010 a cinc països –Regne Unit, Dinamarca, Hongria, Suècia i Espanya (centrat a Catalunya)– que té per objectiu explorar els factors que afavoreixen i ajuden els joves tutelats i extutelats a continuar els seus estudis després de l'escolaritat obligatòria. Cada equip de recerca esta duent a terme un estudi de casos que consisteixen a fer, d'una banda, entrevistes amb responsables de serveis socials i de protecció a la infància, i, d'altra banda, entrevistes en profunditat amb joves d'entre 19 i 21 anys que han estat tutelats almenys un any de la seva vida i que ho estaven a l'edat de 16 anys, i, finalment, entrevistes amb educadors, acollidors o persones que han estat claus a les seves vides. Els joves seleccionats seran entrevistats de nou un any més tard per veure en quina mesura s'han pogut fer els seus plans. L'objectiu del present article és doble: d'una banda, aportar algunes de les dades que s'han obtingut de la primera fase ja conclosa sobre revisió dels estudis existents en aquest àmbit i, de l'altra, obrir un debat, poc present encara al nostre país, que pot culminar el proper març del 2010 amb motiu d'unes jornades a Catalunya on es podran presentar, compartir i debatre els primers resultats de la investigació

Over the last few years, most OECD countries have extended their activation policy to new groups of non-working people, including the long-term unemployed (LTU). However, it is widely known that employers tend to regard LTU people as potentially problematic persons. This is likely to constitute a major obstacle for long-term unemployed jobseekers. On the basis of a survey among employers in a Swiss canton (N = 722), this article aims to shed light on the perception employers have of the long-term unemployed and whether this may matter for their recruitment practices. It also asks what, from the employer point of view, may facilitate access to employment for an LTU person. A key finding is that large companies have a worse image of the long-term unemployed and are less likely to hire them. Furthermore, independent of company size, a test period or the recommendation of a trustworthy person is seen as the factors most likely to facilitate access to jobs for LTU people.

En el presente artículo hemos tratado de analizar las características de las almazaras cooperativas catalanas con la finalidad de destacar no solamente sus elementos más importantes de gestión sino también sus principales debilidades.Las cooperativas se consideran instrumentos útiles para acometer políticas de desarrollo económico y bienestar social. A pesar de ello hay un gran debate abierto acerca de la eficiencia de estas organizaciones, que plantean el interrogante de si están en condiciones de competir con éxito en una economía cada vez más abierta, liberalizada y global. A través de las encuestas que hemos realizado al conjunto de las cooperativas oleícolas de Catalunya, hemos podido averiguar sus características distintivas, así como las principales desventajas y problemas a los que se enfrentan. Creemos puede ser de interés analizar las características de estas organizaciones, que tanto desde el punto de vista organizativo como de recursos humanos, como financiero, las hace diferentes de otro tipo de organizaciones pero que sin embargo, han de hacer frente a un mercado cada día más exigente y competitivo.

Fundamento: La prevalencia de discapacidad en la población general presenta una gran variabilidad geográfica, de manera que identificar aquellos factores que pudieran explicarla será importante para la planificación de políticas sociales. En este trabajo se analiza la variabilidad de la discapacidad por comunidades autónomas desde una doble vertiente, los factores individuales y del entorno. Métodos: Los datos proceden principalmente de la Encuesta de Discapacidad, Deficiencias y Estado de Salud de 1999 y del Inebase, ambas del Instituto Nacional de Estadística (INE). Se calculó la prevalencia de discapacidad simple y ajustada por edad de las CCAA. Se analizan los factores individuales asociados a la discapacidad mediante una regresión logística y los factores individuales y de la comunidad autónoma conjuntamente con una regresión logística de dos niveles. Resultados: La prevalencia de discapacidad muestra una diferencia máxima de 5,75 puntos entre las comunidades autónomas. En la regresión logística la comunidad de residencia fue estadísticamente significativa (OR: 3,35 en la de mayor prevalencia respecto a la de menor) junto con otras variables individuales: edad (OR de 40-64= 1,78 OR de 65-79= 1,87 y OR de >79= 3,34), sexo (OR mujer= 0,66), situación laboral (OR sin trabajo=2,25 OR amas casa/estudiante=1,39 y OR otros=2,03), estado de salud (OR regular= 1,69 OR malo/muy malo= 2,05) y enfermedades crónicas (OR 1-3=1,56 OR4-6=1,82 OR>6=2,59). En la regresión de dos niveles las variables individuales explican poca varianza (s=0,261) y ninguna de las variables relativas a las CCAA mejora el modelo. Conclusiones: Las características individuales no explican suficientemente la variabilidad de la discapacidad entre CCAA y no se han identificado variables del entorno que sean significativas.

The private sector plays an increasing and relevant role in highway funding and management. For that reason, the regulation designed and enforced by public authorities becomes even more important for the social welfare results generated by this process. In this study, we analyze the current trends in highway funding and management paying special attention on the recent process of privatization and its motivations. Since public ownership and regulation are substitutes for government intervention, we check the hypothesis that highways privatization induces more strict regulation. Indeed, we observe that as the private sector increases its size, toll regulation becomes more detailed.

Some bilingual societies exhibit a distribution of language skills that can- not be explained by economic theories that portray languages as pure commu- nication devices. Such distribution of skills are typically the result of public policies that promote bilingualism among members of both speech commu- nities (reciprocal bilingualism). In this paper I argue that these policies are likely to increase social welfare by diminishing economic and social segmenta- tion between the two communities. However, these gains tend to be unequally distributed over the two communities. As a result, in a large range of circum- stances these policies might not draw su¢ cient support. The model is built upon the communicative value of languages, but also emphasizes the role of linguistic preferences in the behavior of bilingual individuals.
