What is the european social model? an aproximation based on Spanish case

The public perception of the EU in Spain varies greatly. The most positive aspects of Spanish membership are associated with the consolidation of democracy, economic growth, the introduction of the euro, the growth in employment and structural and cohesion funds, the increase in the female participation rate, and the equal opportunities policies. The analysts are in favour of common objectives in the employment policy and multi-level government. The less positive aspects of the EU are the risks of losing social protection and loss of employment in some sectors due to mergers of multinationals and delocalization of companies towards Eastern Europe. The continuous demands for reform of the welfare state, the toughening of the conditions of access to social benefit and the reform of the labour market are also seen as problematic issues. Risks of competitive cuts and social dumping.

Entradas y salidas de empresas: un contraste de las hipótesis de independencia, simetría y simultaneidad

En este trabajo se analiza una vía alternativa en el debate de la convergencia regional en España: el estudio de la dinámica industrial de sus Comunidades Autónomas. Para ello se analizan los flujos de entrada y salida de establecimientos industriales en las manufacturas delas regiones españolas y se abordan los factores de carácter sectorial o regional que inciden sobre la movilidad industrial. Las specificaciones econométricas adoptan la estructura de un sistema de ecuaciones y cubren las tres hipótesis fundamentales que se han abordado en laliteratura (independencia, simetría y simultaneidad) a partir de un panel de datos construido con informaciones procedentes del Registro de Establecimientos Industriales y la Encuesta Industrial. Palabras clave: demografía industrial, sistemas de ecuaciones, datos de panel

New business formation and employment growth: some evidence for the Spanish manufacturing industry

This paper explores the effects of new business formation on employment growth in Spanish manufacturing industries. New firms are believed to make an important contribution to economic growth but the extent of this contribution is unclear. We consider time lags of new firm formation as explanatory variables of employment change and identify how long the effect of new firm entries on employment lasts. Our main results show that the effects of new business formation are positive in the short term, negative in the medium term and positive in the long term, thus confirming the existence of indirect supply-side effects found in similar studies for other countries. Key words: regional growth, firm entry, time lags and Spanish economy. JEL classifications: L00, L60, R11, R12

The Determinants of pricing in pharmaceuticals: are U.S. prices really higher than those of Canada?

This paper studies price determination in pharmaceutical markets using data for 25 countries, six years and a comprehensive list of products from the MIDAS IMS database. We show that market power and the quality of the product has a significantly positive impact of prices. The nationality of the producer appears to have a small and often insignificant impact on prices, which suggests that countries which regulates prices have relatively little power to do it in a way that advances narrow national interest. We produce a theoretical explanation for this phenomenon based on the fact that low negotiated prices in a country would have a knock-on effect in other markets, and is thus strongly resisted by producers. Another key finding is that the U.S. has prices that are not significantly higher than those of countries with similar income levels. This, together with the former observation on the effect of the nationality of producers casts doubt on the ability of countries to purs

Multimarket contact in pharmaceutical markets

The purpose of this paper is to analyze the effect of multimarket contact on the behavior of pharmaceutical firms controlling for different levels of regulatory constraints using IMS MIDAS database. Theoretically, firms that meet in several markets are expected to be capable of sustaining implicitly more profitable out- comes, even if perfect monitoring is not possible. Firms may find it profitable to redistribute their market power among markets where they are operating. We present evidence for nine OECD countries with different degrees of regulation and show that regulation affects the importance of economic forces on firms' price setting behavior. Furthermore, our results confirms the presence of the predictions of the multimarket theory for more market friendly countries (U.S. and Canada) and less regulated ones (U.K., Germany, Netherlands), in contrast, for highly regulated countries (Japan, France, Italy and Spain) the results are less clear with some countries being

La polémica identidad de los valencianos: a propósito de las reformas de los Estatutos de Autonomía

La cuestión de las nacionalidades se ha reabierto en España al calor de las reformas de los Estatutos de Autonomía impulsadas por el gobierno socialista de José Luís Rodríguez Zapatero. Sin embargo, no todas las reformas emprendidas por las Comunidades Autónomas han reivindicado el mismo tratamiento identitario en sus Estatutos. Este trabajo pretende ofrecer alguna luz, desde la ciencia política, para explicar el diferente curso identitario que caracteriza a la Comunidad Valenciana en relación a otras comunidades, como es el caso de Cataluña o Andalucía. A tal fin se exponen los modelos de autopercepción identitaria y su distribución o anclaje entre los valencianos, junto con el análisis de la repercusión de esta dimensión en términos electorales. Esos datos permiten al autor sugerir algunas explicaciones sobre el pacto estatutario alcanzado en torno a la identidad de los valencianos y sobre el comportamiento de los principales actores políticos valencianos en el proceso de reforma estatutaria de 2006.

Disseny d'un acoblador direccional amb metamaterials

En aquest treball es descriu el disseny d’un acoblador direccional en anell de 1.5λ, habitualment anomenat rat-race, mitjançant metamaterials. S’utilitza una línia microstrip amb gap capacitiu en sèrie i una cel·la left-handed basada en un ressonador d’anells oberts complementari (CSRR), fent així possible una reducció de la longitud de la línia de 270º en un factor 5. Gràcies a aquesta disminució de longitud, l’àrea del dispositiu és 4 vegades menor que la del rat-race convencional. La mesura mostra que el comportament és el desitjat a la freqüència d’operació.

Recomanacions sobre pràctiques higièniques per embotits fermentats tradicionals

La seguretat i qualitat dels aliments és actualment una de les majors preocupacions dels consumidors europeus i una prioritat política en Estats Units i Europa, a través del Programa Agenda 2000 i el Llibre Blanc de seguretat alimentària (2000). Aquest llibre blanc va indicar 3 prioritats: 1. Crear una Agència Europea dels Aliments, 2. Implementar un enfocament coherent de la granja a la taula en termes de legislació alimentària, 3. Establir el principi a partir del qual la responsabilitat clau de la seguretat alimentària recau en els operadors alimentaris. Els estats membres són els encarregats de vigilar i controlar a aquests productors i la Comissió Europea comprova l’eficiència dels Estats per a controlar-los (subsidiari). La legislació comunitària estableix els objectius de les normes d’higiene (en vigor des del 20 de maig del 2004) a través de l’ús d’un enfocament integrat de tota la cadena alimentària (des de la granja a la taula), per a garantir un alt nivell de protecció en termes de seguretat sanitària dels productes alimentosos. A Europa, els productes artesanals i/o tradicionals gaudeixen d’una posició privilegiada als ulls dels consumidors que demanden productes autèntics, de qualitat i d’origen garantit.

Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MUSIASEM): an outline of rationale and theory

This paper presents an outline of rationale and theory of the MuSIASEM scheme (Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism). First, three points of the rationale behind our MuSIASEM scheme are discussed: (i) endosomatic and exosomatic metabolism in relation to Georgescu-Roegen’s flow-fund scheme; (2) the bioeconomic analogy of hypercycle and dissipative parts in ecosystems; (3) the dramatic reallocation of human time and land use patterns in various sectors of modern economy. Next, a flow-fund representation of the MUSIASEM scheme on three levels (the whole national level, the paid work sectors level, and the agricultural sector level) is illustrated to look at the structure of the human economy in relation to two primary factors: (i) human time - a fund; and (ii) exosomatic energy - a flow. The three levels representation uses extensive and intensive variables simultaneously. Key conceptual tools of the MuSIASEM scheme - mosaic effects and impredicative loop analysis - are explained using the three level flow-fund representation. Finally, we claim that the MuSIASEM scheme can be seen as a multi-purpose grammar useful to deal with sustainability issues.

An application of MSIASM to Chinese exosomatic energy metabolism

The methodology of Multi-Scale Integrated The methodology of Multi-Scale Integrated Analysis of Societal Metabolism (MSIASM) is applied to analyze the Chinese economy. This paper presents four tasks: (i) identifying a set of benchmarks that makes it possible to compare various characteristics of the Chinese economy with those of other country groups and the world (level) average; (ii) explaining the differences over the selected set of benchmarks, by looking at the characteristics of the various sub-sectors of the Chinese economy; (iii) understanding existing trends and future feasible future development paths for China by studying the existence of reciprocal constraints between the whole economy and its sub-sectors; and (iv) examining plausible future scenarios of development.

Different trajectories of exosomatic energy metabolism for Brazil, Chile and Venezuela: using the MSIASM approach

Economic development goes hand in hand with an increase in the consumption of natural resources. Some analysts use material flows to describe such relationship [Eurostat 2001, Weisz et al., 2006], or exergy [Ayres et al., 2003]. Instead this paper will use a characterisation of the exosomatic energy metabolism based on expected benchmark values to describe possible constraints to economic development posed by available human time and energy. The aim of the paper is to identify types of exosomatic energy metabolism of different societies to interpret its consequences for economic development. This is done with the application of the accounting methodology called Multi-Scale Integrated Analysis of Societal Metabolism (MSIASM) to the particular case of energy metabolism for the analysis of the economies of Brazil, Chile and Venezuela.

Planta de producción de ácido acético

El presente proyecto trata sobre el diseño de una planta química para la producción de 75000 toneladas al año de ácido acético. Para la consecución de este objetivo utilizamos la carbonilación en continuo de metanol con monóxido de carbono. No obstante, no comercializaremos un solo producto, si no que se ha de ofertar de dos formas. Por un lado, ácido acético glacial (60% de la producción total), que es una solución de acético que como mínimo ha de contener un 98% de ácido y una concentración de agua inferior al 1% y por otro lado, el resto de producción será una solución al 70% en ácido acético.
