Urbanización y consumo: la ingesta de proteínas animales en Barcelona durante los siglos XIX y XX.

Los procesos de urbanización en la Europa occidental han sido analizados desde diversas perspectivas. En unos casos, como resultado de un diverso conjunto de cambios económicos, políticos y sociales y en otros, como causa a su vez de otros procesos posteriores, que habrían reforzado la senda del crecimiento. A menudo estas perspectivas son complementarias, al diferenciarse por las variables dependientes e independientes elegidas en cada caso. Reconocer esta situación, sin embargo, no exime de precisar mejor dos cuestiones: cómo funcionaron los mecanismos de transmisión de los cambios observados entre unas y otras variables, y cómo evolucionaron en el tiempo estos mecanismos. En el presente artículo avanzaremos algunas respuestas a estas cuestiones. Con esta finalidad tomaremos como referencia aquellos razonamientos que ponen el acento en la evolución de los ingresos, para explicar dos aspectos del crecimiento económico: los cambios que se experimentaron en la dieta en los núcleos urbanos durante los siglos XIX y XX y los cambios que se experimentaron en la disponibilidad de sus componentes. En estos análisis también se consideran los cambios en los precios, pero en la medida que esta variable acostumbraba a tener valores más altos en las ciudades y que sus tendencias a escala espacial tendieron a confluir, su consideración acostumbra a ocupar un lugar secundario en los análisis mencionados. En este artículo discutiremos estas cuestiones, analizando el consumo de proteínas animales en la ciudad de Barcelona entre mediados del siglo XIX y 1935.

The Spanish cadet in the European military context a comparative analysis of the professional socialisation

Research on the attitudes, motivations and social and political behavior of European cadets have been made throughout the last decade. Nowadays Spain also joins those surveys. Thru the analysis of polling data, we can consider the different attitudes of Spanish cadets in relation with the other European ones. The conclusion is that although the Spanish political transition to democracy has not ended already in the military teaching system, there are a lot of similarities among Spanish and European cadets.

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.

Composition of Greenhouse Gas Emissions in Spain: an Input-Output Analysis

Extending the traditional input-output model to account for the environmental impacts of production processes reveals the channels by which environmental burdens are transmitted throughout the economy. In particular, the environmental input-output approach is a useful technique for quantifying the changes in the levels of greenhouse emissions caused by changes in the final demand for production activities. The inputoutput model can also be used to determine the changes in the relative composition of greenhouse gas emissions due to exogenous inflows. In this paper we describe a method for evaluating how the exogenous changes in sectorial demand, such as changes in private consumption, public consumption, investment and exports, affect the relative contribution of the six major greenhouse gases regulated by the Kyoto Protocol to total greenhouse emissions. The empirical application is for Spain, and the economic and environmental data are for the year 2000. Our results show that there are significant differences in the effects of different sectors on the composition of greenhouse emissions. Therefore, the final impact on the relative contribution of pollutants will basically depend on the activity that receives the exogenous shock in final demand, because there are considerable differences in the way, and the extent to which, individual activities affect the relative composition of greenhouse gas emissions. Keywords: Greenhouse emissions, composition of emissions, sectorial demand, exogenous shock.

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.

Auctions for government securities: a laboratory comparison of uniform, discriminatory and spanish designs

The Bank of Spain uses a unique auction format to sell government bonds, which can be seen as a hybrid of a uniform and a discriminatory auction. For winning bids above the average winning bid, buyers are charged the average winning bid, otherwise they pay their respective bids. We report on an experiment that compares this auction format to the discriminatory format, used in most other countries, and to the uniform format. Our design is based on a common value model with multi-unit supply and two-unit demand. The results show significantly higher revenue with the Spanish and the uniform formats than with the discriminatory one, while volatility of prices over time is significantly lower in the discriminatory format than in the Spanish and uniform cases. Actual price dispersion is significantly larger in the discriminatory than in the Spanish. Our data also exhibit the use of bid-spreading strategies in all three designs.

The effect of structural fund spending on the spanish regions: an assessment of the 1994-99 objective 1 CSF

This paper analyzes the growth and employment effects of the 1994-99 Community Support Framework (CSF) for the Objective 1 Spanish regions using a simple supply-side model estimated with a panel of regional data. The results suggest that the impact of the Structural Funds in Spain has been quite sizable, adding around a percentage point to annual output growth in the average Objective 1 region and 0.4 points to employment growth. Over the period 1994-2000, the Framework has resulted in the creation of over 300,000 new jobs and has eliminated 20% of the initial gap in income per capita between the assisted regions and the rest of the country.

How universal is behavior? A four country comparison of spite, cooperation and errors in voluntary contribution mechanisms

This paper studies behavior in experiments with a linear voluntary contributions mechanism for public goods conducted in Japan, the Netherlands, Spain and the USA. The same experimental design was used in the four countries. Our 'contribution function' design allows us to obtain a view of subjects' behavior from two complementary points of view. If yields information about situations where, in purely pecuniary terms, it is a dominant strategy to contribute all the endowment and about situations where it is a dominant strategy to contribute nothing. Our results show, first, that differences in behavior across countries are minor. We find that when people play "the same game" they behave similarly. Second, for all four countries our data are inconsistent with the explanation that subjects contribute only out of confusion. A common cooperative motivation is needed to explain the date.

Estructura metropolitana y funciones de densidad residencial. El caso de la región metropolitana de Barcelona

La relación que se establece entre el nivel de densidad residencial y la accesibilidad al lugar de empleo en el interior de una área urbana parece ser más compleja que la supuesta en el Modelo de Ciudad Monocéntrica. Las estimaciones de funciones de densidad residencial más simples, sustentadas en un modelo teórico que suponía una concentración total del empleo en el distrito central y que utilizaban como única medida de accesibilidad la distancia al centro, han dado paso a estimaciones más sofisticadas donde la distancia al centro no es la única medida de accesibilidad utilizada, la función de densidad es más flexible y la densidad no sólo se explica en función de la accesibilidad.

Recent trends in Spanish income distribution: a robust picture of falling income inequality

Income distribution in Spain has experienced a substantial improvement towards equalisation during the second half of the seventies and the eighties; a period during which most OECD countries experienced the opposite trend. In spite of the many recent papers on the Spanish income distribution, the period covered by those stops in 1990. The aim of this paper is to extent the analysis to 1996 employing the same methodology and the same data set (ECPF). Our results not only corroborate the (decreasing inequality) trend found by others during the second half of the eighties, but also suggest that this trend extends over the first half of the nineties. We also show that our main conclusions are robust to changes in the equivalence scale, to changes in the definition of income and to potential data contamination. Finally, we analyse some of the causes which may be driving the overall picture of income inequality using two decomposition techniques. From this analyses three variables emerge as the major responsible factors for the observed improvement in the income distribution: education, household composition and socioeconomic situation of the household head.

Impacto redistributivo desagregado del IVA actual en España: posibles vías de reforma

The VAT is the most revenue tax in the Spanish economy in the year 2000. The aim of this research is to develop an analysis dissintegrated of the distributional effect of the current VAT in Spain, that is to say, this paper assesses the capacity of redistribution of the tax treatment of each expenditure category. It proposes different approaches for the analysis of the redistributive impact differential of each expenditure concept, and it desires to advocate the method of total decomposition of isolated contribution to the global distributional effect of the VAT. In this sense, this study shows the possibilities to identify the guidelines for possible fiscal adjustments of the Value Added Tax to contribute positively to the objectives of social justice, and its respective consequences on the population's welfare.

Suburbanizacion, distribución espacial de la renta y segregación residencial en la región metropolitana de Barcelona

La región metropolitana de Barcelona ha experimentado durante los últimos veinte años un intenso proceso de suburbanización e integración metropolitana. La combinación de ambos procesos ha dejado una profunda huella en el territorio conformando una conurbación policéntrica a la vez que dispersa. Esta nueva realidad plantea algunas preguntas interesantes: (a) ¿cuáles son las características de los municipios que atraen población, (b) ¿cómo se ha redistribuido espacialmente la renta debido al proceso de suburbanización? y (c) ¿se ha intensificado el carácter especializado segregado- de los municipios de la RMB?.

Distribución de la actividad económica y estructura urbana: el caso de la región metropolitana de Barcelona

La RMB es una ciudad de tipo policéntrico en la que resaltan unas ciudades de tamaño medio con elevada presencia de actividad económica y que, en muchos casos, destacan por sus dinámicas de crecimiento endógeno. El objetivo de esta investigación era hallar evidencia empírica en la RMB acerca de los determinantes de la localización de la actividad económica. Un objetivo que, a la par, requería la inclusión del estudio de la estructura urbana de la región para poder evaluar el efecto que en ella ejercen los determinantes de la localización. Si bien los resultados obtenidos con la Exponencial son buenos, la inclusión de formas funcionales de tipo polinómico para capturar los grumos de densidad han demostrado su eficiencia. Aunque la Cubic-Spline obtiene buenos resultados, tiene el inconveniente de no poder interpretar sus coeficientes. No obstante, nuestra propuesta, la Spline-Lineal, nos permite detectar la presencia de los subcentros que constituyen la región en base a la existencia de gradientes de densidad positivos.
