Economic impacts of alternative water policy scenarios in the Spanish production system: an input-output analysis

The objective of this paper is to analyse the economic impacts of alternative water policies implemented in the Spanish production system. The methodology uses two versions of the input-output price model: a competitive formulation and a mark-up formulation. The input-output framework evaluates the impact of water policy measures on production prices, consumption prices, intermediate water demand and private welfare. Our results show that a tax on the water used by sectors considerably reduces the intermediate water demand, and increases the production and consumption prices. On the other hand, according to Jevons' paradox, an improvement in technical efficiency, which leads to a reduction in the water requirements of all sectors and an increase in water production, increases the amount of water consumed. The combination of a tax on water and improved technical efficiency takes the pressure off prices and significantly reduces intermediate water demand. JEL Classification: C67 ; D57 ; Q25.

Spanish pension system: population aging and immigration policy

There is a widespread consensus in the literature that, as consequence of the demographic transition, the current Spanish pension system will become unsustainable in the next decades. In this article we evaluate the sustainability of the contributory pensions' sub-system, taking into account the demographic projections by the Spanish Statistical Office (INE). A baseline scenario is projected as well as several reforms are simulated, focusing on: (i) selective immigration policy, (ii) changes in the way of setting the pensions and (iii) increase of the legal age of retirement up to 68. The main results are the following. The current system would not incur deficits until 2018, from then deficits will begin to be accumulated. The expenditure in pensions practically would double (from 8.3 % in 2005 to 17.2 % in 2050). A selective immigration policy -towards foreign young people- would help, but does not solve the long-term sustainability of the current system. A policy that combines a pensions' growth at a pace lower than productivity growth and extends the legal age of retirement up to 68 would give solvency to the system beyond 2029

Chemical composition of the small coastal lagoons of the Mediterranean Spanish littoral

About sixty small water bodies (coastal lagoons, marshes, salt pans, channels, springs, etc.) of the Spanish Mediterranean coast were sampled seasonally for one year (1979-1980), in order to study different aspects of their chemical composition. The concentrations of major ions (alkalinity, Cl-, Ca2+, Mg2+, Na+, and K+), nutrients (N.NO-3, N.NO2-, TRP and Si), oxygen and pH were determined for this purpose. The salt concentrations measured range between 0.4 and 361.3 g l-1. The samples have been divided into four classes of salinity (in g l-1): Cl, S < 5; C2, 5 40. Within these classes, the pattern of ionic dominance recorded is remarkably constant and similar to that found in most coastal lagoons (Cl- > So42- > Alk., for the anions, and Na+ > Mg2+ > Ca2+ > K+, for the cations), although other models occur especially in the first class. The dominance of Na+ and Cl-, as well as the molar ratios Mg2+/Ca2+ and Cl- / SO42- ,clearly increase from class Cl to class C4. The hyperhaline waters include different subtypes of the major brine type"c",, of EUGSTER & HARDIE (1978), the Na+ - (Mg2+) - Cl- - (SO42-) being the most frequent. Nutrient concentrations fall within a wide range (N.NO3 from 0.1 to 1100 mg-at 1-1; PRT from 0.01 to 23.56 mg-at l-1 and Si from 1.0 to 502.0 mg-at l-1). The oxygen values are very variable too, ranging between 0 and 14.4 ml l-1. Four different patterns of nutrient distribution have been distinguished based on the mean concentrations of N.NO3-, and TRP (mean values in mg-at l-1): A, N.NO3- < 10, TRP > l ; B, N.NO3- > 100, TRP < 1; C, 10 < N.NO3- < 100, TRP < 1; C, D, N.NO3- < 10, TRP < 1. As a rule, lagoons of low salinity (C1 and C2 classes) display the nutrient pattern C, and lagoons of high salinity (C3 and C4) show the nutrient pattern D. Model A only appears in waters of very low salinity, whereas model B does not seem to be related to salinity.

Psychometric Properties of the Spanish Human System Audit Short-Scale of Transformational Leadership

The aim of this research is to examine the psychometric properties of a Spanish version of the Human System Audit transformational leadership short-scale (HSA-TFL-ES). It is based on the concept of Bass developed in 1985. The HSA-TFL is a part of the wider Human System Audit frame. We analyzed the HSA-TFL-ES in five different samples with a total number of 1,718 workers at five sectors. Exploratory Factor Analysis corroborated a single factor in all samples that accounted for 66% to 73% of variance. The internal consistency in all samples was good (α = .92 - .95). Evidence was found for the convergent validity of the HSA-TFL-ES and the Multifactor Leadership Questionnaire. These results suggested that the HSA-TFL short-scale is a psychometrically sound measure of this construct and can be used for a combined and first overall measurement.

The Catalan Parliament and the Mediterranean: a preliminary assessment

This study consists of four parts. It begins with an overview of the Spanish political system and how Catalonia fits into it, with an emphasis on Spain’s foreign policy decision-making process (section 1). The following sections cover Catalonia and the Mediterranean (section 2), before concentrating on the Catalan Parliament (section 3). This study then concludes with a summary of the main findings and a set of guidelines for possible future research.

Diversity and regional inequalities: Assessing the outcomes of the Spanish 'System of Health Care Services'

The consolidation of a universal health system coupled with a process of regionaldevolution characterise the institutional reforms of the National Health System(NHS) in Spain in the last two decades. However, scarce empirical evidence hasbeen reported on the effects of both changes in health inputs, outputs andoutcomes, both at the country and at the regional level. This paper examinesthe empirical evidence on regional diversity, efficiency and inequality ofthese changes in the Spanish NHS using cross-correlation, panel data andexpenditure decomposition analysis. Results suggest that besides significantheterogeneity, once we take into account region-specific needs there is evidenceof efficiency improvements whilst inequalities in inputs and outcomes, althoughmore visible , do not appear to have increased in the last decade. Therefore,the devolution process in the Spanish Health System offers an interesting casefor the experimentation of health reforms related to regional diversity butcompatible with the nature of a public NHS, with no sizeable regionalinequalitiest.

Urban spatial structure and suburbanisation. The case of the Barcelona Metropolitan

The metropolitan spatial structure displays various patterns, sometimes monocentricity and sometimes multicentricity, which seems much more complicated than the exponential density function used in classic works such as Clark (1961), Muth (1969) or Mills (1973) among others, can effectively represent. It seems that a more flexible density function,such as cubic spline function (Anderson (1982), Zheng (1991), etc.) to describe the density-accessibility relationship is needed. Also, accessibility, the fundamental determinant of density variations, is only partly captured by the inclusion of distance to the city centre as an explanatory variable. Steen (1986) has proposed to correct that miss-especification by including an additional gradient for distance to the nearest transportation axis. In identifying the determinants of urban spatial structure in the context of inter-urban systems, some of the variables proposed by Muth (1969), Mills (1973) and Alperovich (1983) such as city age or population, make no sense in the case of a single urban system. All three criticism to the exponential density function and its determinants apply for the Barcelona Metropolitan Region, a polycentric conurbation structured on well defined transportation axes.

Inmigrantes en formación: desplazamientos y fijaciones de la cohesión social promovida por el Estado del Bienestar en la formación para la inserción laboral de las personas migrantes en Barcelona

En la investigación llevada a cabo nos hemos aproximado, desde un punto de vista cualitativo, a los recursos de formación para la inserción sociolaboral dirigidos a personas inmigrantes en la ciudad de Barcelona. Dicha formación forma parte de los recursos del sistema de bienestar español, caracterizado como mediterráneo (Esping-Andersen, 1990; Ferrara 1996; Moreno, 2002); y responde a los lineamientos de las políticas de integración dirigidas al mencionado colectivo. Para llevar a cabo el trabajo hemos adoptado la perspectiva metodológica de Antropología de las Políticas (Shore y Wright, 1997). La construcción del marco teórico bebió de los aportes que enfatizan el papel político de los Estados-nación en relación con los procesos migratorios (Sayad, 2010), señalando que la inmigración, lejos de ser un proceso que les “sucede” a las sociedades de recepción, es un fenómeno conformado por éstas (Geddes, 2006). La profunda transformación en los modos de la cohesión social (Castel, 1997) en las sociedades de recepción de personas inmigradas constituyen el contexto en el cual actúan las políticas de integración. A través de las condiciones de acceso a los recursos de formación para la inserción sociolaboral, mediante los contenidos impartidos y las maneras en que lo hacen, se configuran los inmigrantes “deseados” e “indeseados” funcionando como “fronteras organizativas”. Los resultados del análisis, indican que se espera que las personas inmigradas sean sujetos disponibles y activos, donde la formación emerge más que como un derecho que favorece y consolida la cohesión social o la “integración”, como un recurso que hay que “merecer”. Paralelamente a dicha emergencia, la formación se perfila como un dispositivo que antes que servir para la promoción social es un débil sustituto del empleo, fatigosamente anhelado por las personas que llevan a cabo los procesos formativos.

What explains productivity differentials across spanish cities?

This paper estimates the determinants of productivity differentials across urban areas in Spain. To do so we resort to Spanish Social Security administrative data (MCVL) matched with workers’ fiscal information. We use two-step approach that allows us to control for the confounding effects due to the sorting of more productive workers and more productive firms in bigger cities. Our results indicate that city size is a significant determinant of productivity differentials across Spanish urban areas. We estimate an elasticity of urban agglomeration of 3.3%, which is within the range of values already observed in other countries. We also find that the level of human capital, firm size and the level of industrial specialization also matters in order explain productivity differentials across Spanish cities.

Una estimación del coste marginal en bienestar del sistema impositivo en España

Actual tax systems do not follow the normative recommendations of yhe theory of optimal taxation. There are two reasons for this. Firstly, the informational difficulties of knowing or estimating all relevant elasticities and parameters. Secondly, the political complexities that would arise if a new tax implementation would depart too much from current systems that are perceived as somewhat egalitarians. Hence an ex-novo overhaul of the tax system might just be non-viable. In contrast, a small marginal tax reform could be politically more palatable to accept and economically more simple to implement. The goal of this paper is to evaluate, as a step previous to any tax reform, the marginal welfare cost of the current tax system in Spain. We do this by using a computational general equilibrium model calibrated to a point-in-time micro database. The simulations results show that the Spanish tax system gives rise to a considerable marginal excess burden. Its order of magnitude is of about 0.50 money units for each additional money unit collected through taxes.

Employment descentralisation: polycentric compaction or sprawl? The case of the Barcelona Metropolitan Region 1986-1996

The Barcelona Metropolitan Region (BMR) has been repeatedly characterised as a polycentric-type urban system. The aim of this study is to corroborate this affirmation by making use of a methodology that enables the identifying of employment subcentres and valuing of the degree of polycentrism of the BMR in 1986 and 1996. The results obtained in the two years confirm the existence and extension of the polycentrism.

El control electrònic com a pena

El control electrònic s'ha aplicat a l'àmbit comparat, principalment, com a instrument de control de l'arrest domiciliari com a mesura cautelar i com a pena, i també en l'àmbit penitenciari junt a formes de compliment de la pena de presó en semillibertat. Des d'una justificació retribucionista de la pena es pot acceptar el control electrònic perquè té suficiència punitiva, pot aplicar-se de forma proporcional i no es degradant. D'altra banda, una justificació utilitarista de la pena accepta el control electrònic perquè redueix la delinqüència. Tot i que la seva aplicació a l'àmbit comparat no ha estat majoritàriament com a alternativa a la presó, es tracta d'un instrument que pot conferir credibilitat i potencial reduccionista a un sistema de penes alternatives. A l'ordenament espanyol pot considerar-se una mesura susceptible de ser aplicada dins el marc constitucional, malgrat afecti a determinats drets fonamentals. La seva previsió normativa com a pena i a l'àmbit penitenciari es molt escassa i presenta diversos problemes interpretatius. Quant a la seva aplicació a España, es reduïda a l'àmbit penitenciari i pràcticament inexistent com a pena. La credibilitat i potencial reduccionista que pot aportar el control electrònic a un sistema de penes alternatives permet defensar l'ampliació del seu ús al nostre ordenament en els supòsits ja previstos normativament i en d'altres de nous.

Programa d'introducció al dret espanyol per a estudiants d'intercanvi

El projecte "Programa d'introducció al dret espanyol per a estudiants d'intercanvi" s'ha dut a terme a la Facultat de dret de la Universitat de Barcelona des del mes de juny de 2007 al mes de setembre de 2008. Ha consistit en iniciar l’esmentat programa que suposava, pels estudiants d’intercanvi sol·licitants, la consecució d’un Diploma d’Introducció al Dret espanyol, expedit per la Facultat de Dret de la UB, a banda del reconeixement dels crèdits cursats a Barcelona. L’objectiu va ser proposar canvis en el plantejament curricular, en concret la posada en marxa de les assignatures del Diploma: Introducció al Dret Privat, Introducció al Dret públic, Introducció al sistema processal espanyol, i Bases del sistema legal espanyol. Com a tasca prèvia que havia de garnatir l’èxit es va fer una difusió del programa a les universitats d’origen i es va articular un sistema d’acollida als estudiants que es va demostrar molt útil al principi de curs per a informacions diverses, però que després va ser infrautilitzat. Pel que fa a les assignatures, es van plantejar com un anàlisi dels trets fonamentals i diferencials del nostre dret, utilitzant elements de comparació amb els ordenaments dels països dels alumnes, però sense fer un exercici estricte de dret comparat. La taxa de rediment va ser alta – 75% - però es va detectar un problema, la insuficient preparació idomàtica, que depassa l’organització del programa. També es va considerar un repte pedagògic important: la heterogeneïtat dels estudiants tant en la seva formació jurídica prèvia –assignatures cursades en la seva Universitat-, com en relació al sistema legal del país del qual provenien, en relació al sistema espanyol. Per aquest motiu, el plantejament del curs i els materials a utilitzar va dependre en bona mesura del conjunt del grup al qual es va dirigr cada assignatura en concret.

Work, risk and health: differences between immigrants and natives in Spain

We analyze the impact of working and contractual conditions, particularly exposure to job risks, on the probability of acquiring a disability. We postulate a model in which this impact is mediated by the choice of occupation, with a level of risk associated to it. We assume this choice is endogenous, and that it depends on preferences and opportunities in the labour market, both of which may differ between immigrants and natives. To test this hypothesis we use data from the Continuous Sample of Working Lives of the Spanish SS system. It contains individual, job and firm information of over a million workers, including a representative sample of immigrants. We find that risk exposure increases the probability of permanent disability by 5.3%; temporary employment also influences health. Migrant status -with differences among regions of origin- significantly affects both disability and the probability of being employed in a risky occupation. Most groups of immigrants work in riskier jobs, but have lower probability of becoming disabled. Nevertheless, our theoretical hypothesis that disability and risk are jointly determined is not valid for immigrants: i.e. for them working conditions is not a matter of choice in terms of health.
