Trade, Extent of the Market, and Economic Growth 1960-1996

We find that trade and domestic market size are robust determinants of economic growth over the 1960-1996 period when trade openness is measured as the US dollar value of imports and exports relative to GDP in PPP US$ ('real openness'). When trade openness is measured as the US dollar value of imports and exports relative to GDP in exchange rate US$ ('nominal openness') however, trade and the size of domestic markets are often non-robust determinants of growth. We argue that real openness is the more appropriate measure of trade and that our empirical results should be seen as evidence in favor of the extent-of-the-market hypothesis.

Desarrollo de una matriz empleo-exposición (MEE) para describir la exposición de los trabajadores a plaguicidas en España (1996-2005)

Introducción: En 2005 se consumían en España más de 100.000 toneladas/año de plaguicidas, en actividades tan diversas como la agricultura y la ganadería o el tratamiento de la madera y la gestión de plagas estructurales. A pesar de los demostrados efectos negativos de estas sustancias sobre la salud de las personas, existe muy poca información relativa a los niveles y la frecuencia de exposición de los trabajadores expuestos, así como de las ocupaciones más afectadas. Este trabajo tiene como objetivo recopilar la información disponible sobre exposición laboral a plaguicidas en España, en forma de una matriz empleo-exposición (MEE), un sistema de información que permite ordenar de forma sistemática la información más relevante sobre ocupaciones, agentes, prevalencia y nivel/intensidad de exposición en un determinado contexto (país, periodo, etc.).

A territorial model of commuting in Catalonia, 1986-1996

Commuting consists in the fact that an important fraction of workers in developed countries do not reside close to their workplaces but at long distances from them, so they have to travel to their jobs and then back home daily. Although most workers hold a job in the same municipality where they live or in a neighbouring one, an important fraction of workers face long daily trips to get to their workplace and then back home.Even if we divide Catalonia (Spain) in small aggregations of municipalities, trying to make them as close to local labour markets as possible, we will find out that some of them have a positive commuting balance, attracting many workers from other areas and providing local jobs for almost all their resident workers. On the other side, other zones seem to be mostly residential, so an important fraction of their resident workers hold jobs in different local labour markets. Which variables influence an area¿s role as an attraction pole or a residential zone? In previous papers (Artís et al, 1998a, 2000; Romaní, 1999) we have brought out the main individual variables that influence commuting by analysing a sample of Catalan workers and their commuting decisions. In this paper we perform an analysis of the territorial variables that influence commuting, using data for aggregate commuting flows in Catalonia from the 1991 and 1996 Spanish Population Censuses.These variables influence commuting in two different ways: a zone with a dense, welldeveloped economical structure will have a high density of jobs. Work demand cannot be fulfilled with resident workers, so it spills over local boundaries. On the other side, this economical activity has a series of side-effects like pollution, congestion or high land prices which make these areas less desirable to live in. Workers who can afford it may prefer to live in less populated, less congested zones, where they can find cheaper land, larger homes and a better quality of life. The penalty of this decision is an increased commuting time. Our aim in this paper is to highlight the influence of local economical structure and amenities endowment in the workplace-residence location decision. A place-to-place logit commuting models is estimated for 1991 and 1996 in order to find the economical and amenities variables with higher influence in commuting decisions. From these models, we can outline a first approximation to the evolution of these variables in the 1986-1996 period. Data have been obtained from aggregate flow travel-matrix from the 1986, 1991 and 1996 Spanish Population Censuses

Mathematics in Catalonia: 1996-2002

The aim of this article is to present the main conclusions of the Report on research in Catalonia for the area of mathematics**. The report was prepared by Joaquim Bruna, Marta Sanz, Joan de Solà-Morales and the author of this text, and published by the Institute for Catalan Studies in 1998. In the report, scientific activity in the area of mathematics was measured essentially by examining two parameters: papers published in specialised journals and doctoral theses read. It should be recognised that a considerable amount of activity in the field of mathematics consists of applying existing knowledge to the resolution of practical technological problems that arise in particular companies. This kind of scientific activity was not measured in any way in the report due to the difficulty of obtaining objective data. This article is divided into the following sections: human resources, scientific production, funding, research publications, research centres, and conclusions.

A.A.V.V.: Montbarbat (1978-1986), Lloret de Mar, 1996

Debe reconocerse que en estos años próximos al fin del milenio la publicación de estudios sobre el mundo ibérico goza de excelente salud, cuando menos en volumen. Artículos, ponencias y comunicaciones amenazan con abrumar al lector más impenitente. Por ello resulta aleccionador acudir al meritorio trabajo de Fernando Quesada: "La cultura ibérica: una aproximación bibliográfica (1992-1993)", RE/b, 1, 1994, 335-377, que reúne la producción en revistas y series no excesivamente locales -imposibles de controlar, por otro lado-, y comprobar un balance de unos doscientos títulos anuales. Ahora bien, si consideramos el número de monografías, nos situaremos en un plano selectivo, que rondará la docena al año. Diversos factores -y entre ellos la desidia de diferentes niveles administrativos y académicos- parecen confabularse para que no se disponga de un conjunto de memorias impresas proporcional al volumen de excavaciones realizadas en las dos últimas décadas.

¿Merece la pena coligarse? La formación de gobiernos minoritarios en España, 1977-1996

Este trabajo trata de explicar los motivos que han llevado a los partidos políticos españoles a optar, en los procesos de formación de gobierno en situaciones parlamentarias minoritarias celebrados desde 1977, por la formación de gobiernos minoritarios. Contrariamente a lo sostenido por las teorías formales de las coaliciones políticas, la solución al proceso de formación de gobierno en el caso español responde a los cálculos estratégicos de los partidos políticos implicados en el fenómeno coalicional. Como se argumentará, la formación de gobiernos minoritarios en España se configura como soluciones racionales desde una óptica metodológica multidimensional.

Els eixos organitzadors de la informació hanestat les Àrees de Coneixement i les Universitats. La informació recollida s'ha articulat al voltant de diversesqüestions cabdals relatives als Grups de Recerca: Projectes de recerca obtinguts per part de diversos organismes subvencionants, la productivitat contemplada des de la vessant de la publicació d'articles científics, el finançament obtingut per part de diverses Administracions i entitats privades, la infrastructura amb la que compten, les característiques d'arranjament d'aquests Grups, i, finalment, les condicions, valoracions, expectatives i gestió dels recursos dels Grups de Recerca.

Estimacions hidrològiques i de moviment de sediment a la riuada del 7 d'Agost de 1996 a la conca del Barranco de Arás (Pirineu aragonès)

L'avinguda al Barranco de Arás a la vall de Biescas és un esdeveniment hidrològic de caràcter extrem de tipus catastròfic, amb un període de recurrència superior als 1000 anys. Es va produir com a conseqüència d'una tempesta plujosa associada al pas d'un front fred pel Pirineu central el 7 d'agost de 1996. La tempesta va descarregar 200 mm h-1 al fons de la vall de Biescas i 500 mm h-1 a Betés, el nucli de la tempesta, quantitats que corresponen a períodes de recurrència aproximats de 100 i 500 anys respectivament.
