Origins and efficiency of the electric industry regulation in Spain, 1910-1936

The aim of this paper is to discover the origins of utility regulation in Spain, and to analyse, from a microeconomic perspective, its characteristics and the impact of regulation on consumers and utilities. Madrid and the Madrilenian utilities are taken as a case study. The electric industry in the period studied was a natural monopoly2. Each of the three phases of production, generation, transmission and distribution, had natural monopoly characteristics. Therefore, the most efficient form to generate, transmit and distribute electricity was the monopoly because one firm can produce a quantity at a lower cost than the sum of costs incurred by two or more firms. A problem arises because when a firm is the single provider it can charge prices above the marginal cost, at monopoly prices. When a monopolist reduces the quantity produced, price increases, causing the consumer to demand less than the economic efficiency level, incurring a loss of consumer surplus. The loss of the consumer surplus is not completely gained by the monopolist, causing a loss of social surplus, a deadweight loss. The main objective of regulation is going to be to reduce to a minimum the deadweight loss. Regulation is also needed because when the monopolist fixes prices at marginal cost equal marginal revenue there would be an incentive for firms to enter the market creating inefficiency. The Madrilenian industry has been chosen because of the availability of statistical information on costs and production. The complex industry structure and the atomised demand add interest to the analysis. This study will also provide some light on the tariff regulation of the period which has been poorly studied and will complement the literature on the US electric utilities regulation where a different type of regulation was implemented.

"¡Mezquita No!: the origins of mosque opposition in Spain

This paper examines why mosque opposition has been more frequent in Catalonia than in other Spanish regions. A comparison is conducted between the metropolitan areas of Barcelona, where opposition has been most prevalent, and Madrid, where it has been strikingly absent. A relational approach is employed to highlight the factors in Barcelona that have complicated the reception of mosques and the populations they serve. These factors include pronounced socio-spatial divisions and a lack of confidence in the state's commitment to managing the challenges that accompany immigration. The prevalence of these factors in Barcelona has resulted in the integration of mosque debates into more general struggles over urban privilege and state recognition, explaining the high degree of opposition. These findings highlight the importance of studying conflicts related to religious and cultural diversification in context, as such conflicts are inextricably linked to the lived spaces and local structures in which they develop.

Persecution perpetuated: The medieval origins of anti-semitic violence in Nazi Germany

How persistent are cultural traits? This paper uses data on anti-Semitism in Germany and finds continuity at the local level over more than half a millennium. When the Black Death hit Europe in 1348-50, killing between one third and one half of the population, its cause was unknown. Many contemporaries blamed the Jews. Cities all over Germany witnessed mass killings of their Jewish population. At the same time, numerous Jewish communities were spared these horrors. We use plague pogroms as an indicator for medieval anti-Semitism. Pogroms during the Black Death are a strong and robust predictor of violence against Jews in the 1920s, and of votes for the Nazi Party. In addition, cities that saw medieval anti-Semitic violence also had higher deportation rates for Jews after 1933, were more likely to see synagogues damaged or destroyed in the Night of Broken Glass in 1938, and their inhabitants wrote more anti-Jewish letters to the editor of the Nazi newspaper Der Stürmer.

The network origins of aggregate fluctuations

This paper argues that in the presence of intersectoral input-output linkages, microeconomicidiosyncratic shocks may lead to aggregate fluctuations. In particular, itshows that, as the economy becomes more disaggregated, the rate at which aggregatevolatility decays is determined by the structure of the network capturing such linkages.Our main results provide a characterization of this relationship in terms of the importanceof different sectors as suppliers to their immediate customers as well as theirrole as indirect suppliers to chains of downstream sectors. Such higher-order interconnectionscapture the possibility of "cascade effects" whereby productivity shocks to asector propagate not only to its immediate downstream customers, but also indirectlyto the rest of the economy. Our results highlight that sizable aggregate volatility isobtained from sectoral idiosyncratic shocks only if there exists significant asymmetryin the roles that sectors play as suppliers to others, and that the "sparseness" of theinput-output matrix is unrelated to the nature of aggregate fluctuations.

On the origins of electoral systems and political parties. The role of elections in multi-member districts

The old, understudied electoral system composed of multi-member districts, open ballot and plurality rule is presented as the most remote scene of the origin of both political parties and new electoral systems. A survey of the uses of this set of electoral rules in different parts of the world during remote and recent periods shows its wide spread. A model of voting by this electoral system demonstrates that, while it can produce varied and pluralistic representation, it also provides incentives to form factional or partisan candidacies. Famous negative reactions to the emergence of factions and political parties during the 18th and 19th centuries are reinterpreted in this context. Many electoral rules and procedures invented since the second half of the 19th century, including the Australian ballot, single-member districts, limited and cumulative ballots, and proportional representation rules, derived from the search to reduce the effects of the originating multi-member district system in favor of a single party sweep. The general relations between political parties and electoral systems are restated to account for the foundational stage here discussed.

The colonial origins of Civil War

The dominant hypothesis in the literature that studies conflict is that poverty is the main cause of civil wars. We instead analyze the effect of institutions on civil war, controlling for income per capita. In our set up, institutions are endogenous and colonial origins affect civil wars through their legacy on institutions. Our results indicate that institutions, proxied by the protection of property rights, rule of law and the efficiency of the legal system, are a fundamental cause of civil war. In particular, an improvement in institutions from the median value in the sample to the 75th percentile is associated with a 38 percentage points reduction in the incidence of civil wars. Moreover, once institutions are included as explaining civil wars, income does not have any effect on civil war, either directly or indirectly.

The origins and impact of primate segmental duplications

Duplicated sequences are substrates for the emergence of new genes and are an important source of genetic instability associated with rare and common diseases. Analyses of primate genomes have shown an increase in the proportion of interspersed segmental duplications (SDs) within the genomes of humans and great apes. This contrasts with other mammalian genomes that seem to have their recently duplicated sequences organized in a tandem configuration. In this review, we focus on the mechanistic origin and impact of this difference with respect to evolution, genetic diversity and primate phenotype. Although many genomes will be sequenced in the future, resolution of this aspect of genomic architecture still requires high quality sequences and detailed analyses.

Defining the criteria for the evaluation of self-study multimedia language learning materials: do they facilitate or inhibit learner autonomy?

Durant els darrers anys, s’han publicat un gran nombre de materials multimèdia destinats a l’aprenentatge de llengües, la major part dels quals son CD-ROM dissenyats com a cursos per l’autoaprenentatge. Amb aquests materials, els alumnes poden treballar independentment sense l’assessorament d’un professor, i per aquest motiu s’ha afirmat que promouen i faciliten l’aprenentatge autònom. Aquesta relació, però, no es certa, com Phil Benson i Peter Voller 1997:10) han manifestat encertadament:(…) Such claims are often dubious, however, because of the limited range of options and roles offered to the learner. Nevertheless, technologies of education in the broadest sense can be considered to be either more or less supportive of autonomy. The question is what kind of criteria do we apply in evaluating them? En aquest article presentem una investigació conjunta on es defineixen els criteris que poden ser utilitzats per avaluar materials multimèdia en relació a la seva facilitat per permetre l’aprenentatge autònom. Aquests criteris son la base d’un qüestionari que s’ha emprat per avaluar una selecció de CD-ROM destinats a l’autoaprenentatge de llengües. La estructura d’aquest article és la següent: - Una introducció de l’estudi - Els criteris que s’han utilitzar per la creació del qüestionari - Els resultats generals de l’avaluació - Les conclusions que s’han extret i la seva importància pel disseny instructiu multimèdia

Un diàleg de sords: intentant donar sentit al debat sobre la publicació electrònica

Aquest article se centra en les implicacions de la difusió electrònica per al sistema de publicació de revistes basat en la revisió per parells [peer-reviewed]. Per donar sentit a un assumpte tan complex, és de molt ajut mirar-s'ho des de la perspectiva dels orígens del sistema i de les seves tres funcions nuclears: el rànquing en la recerca, facilitar la comunicació interactiva entre els estudiosos i crear un arxiu global del coneixement científic. Cadascuna d’aquestes funcions principals té requeriments diferents que, en certa mesura, se sobreposen però que també entren, d'alguna manera, en conflicte. Internet obre la possibilitat de desenvolupar una varietat de models distints de comunicació científica modulant la intensitat de cadascun d'aquests tres rols que les revistes en paper han desenvolupat i, possiblement, d'altres funcions que no eren ni tan sols imaginables abans del desenvolupament de les xarxes electròniques d'abast planetari. Les implicacions de la distribució electrònica per a la propietat i accés a la literatura científica són profundes i tendeixen a agreujar la ja seriosa crisi dels preus de les revistes que està frenant l'accés a la informació científica. La comunitat d'estudiosos, que és autora del material que aquestes publicacions contenen i, al mateix temps, n'és el principal consumidor, està en possessió de la clau per a solucionar aquesta crisi tot permetent a Internet ser un vehicle que faciliti la difusió d’una recerca finançada des del sector públic en comptes de crear una situació de propietat privada d'aquesta recerca.

La poética del desig: amor i bogeria a l'Orlando furioso

Aquesta tesina, amb el títol "La poètica del desig. amor i bogeria a l'Orlando furioso", proposa una nova lectura del poema de Ludovico Ariosto, prenent com a objectiu l'anàlisi de la bogeria del seu protagonista, el Comte Orlando, "che per amor venne in furore e matto / d'uom che sì saggio era stimato prima". Així doncs, pretenem esbrinar per què davant de la constatació de Matteo Maria Boiardo d'un "Orlando innmorato", Ariosto va respondre amb un "Orlando furioso", narrant així "cosa non detta in prosa mai né in rima". Per arribar fins al fons de la qüestió, ens hem preguntat quins són l'origen, la manifestació textual, la dimensió i el significat del concepte de "furor" en el text; interrogants que ens han conduït cap a una bogeria amorosa que és manifestació externa d'un desig insatisfet. Un concepte que, a més a més d'evocar l"Hercules furens" d'Eurípides i Sèneca, ens remet a la teoria dels humors de Galè, al concepte de 'melancholia' d'Aristòtil i a l'eròtica platònica, al mateix temps que reprodueix els models del que Cesare Segre anomena la 'follie littéraire' característica de l'època medieval. A partir d'aquesta anàlisi s'ha interpretat el text com una apologia de les passions en la que es destrona al savi com a paradigma i model ètic, acabant així amb la imatge de l'home com a "animal rationale", situant per contra la seva "humanitas" ja no en la racionalitat (tampoc en la irracionalitat), sinó en la passionalitat, oferint així un retrat de l'ésser humà com a "animal passionalis" , una criatura intermitja en la que haurien de confluir idealment raó i passió.

Hezbollah's identities and their relevance for cultural and religious IR

This working paper analyses the role of religious and resistance identities in Hezbollah’s transformation and foreign relations. It argues that this Islamist movement has privileged material concerns over the religious dogma when both factors have not been coincidental. To do so, it uses a theoretical framework that presents the main characteristics of the anthropological and political interpretations of the role of culture and religion in defining the behaviour of international actors. In the chapter dedicated to Hezbollah, close attention is paid to the domestic and regional levels of analysis. When assessing Hezbollah’s religious identity, this paper argues that the salience of the pan-Islamic religious identity in Hezbollah’s origins has been replaced by an increased political pragmatism. It also argues that the fight against Israel represents Hezbollah’s raison d’être and that its resistance identity has not suffered major transformations and has been easily combined with religious rhetoric. Linking Hezbollah’s case study with the theoretical framework, this paper argues that political conceptions of cultural and religious identities provide the best analytical tool to understand the evolution of this Islamist movement.

Regional value added in Italy over the long run (1891-2001): linking indirect estimates with official figures, and implications

This paper presents value added estimates for the Italian regions, in benchmark years from 1891 until 1951, which are linked to those from official figures available from 1971 in order to offer a long-term picture. Sources and methodology are documented and discussed, whilst regional activity rates and productivity are also presented and compared. Thus some questions are briefly reconsidered: the origins and extent of the north-south divide, the role of migration and regional policy in shaping the pattern of regional inequality, the importance of social capital, and the positioning of Italy in the international debate on regional convergence, where it stands out for the long run persistence of its disparities.

Pork Value Chains: A Comparison of Catalonia, Spain and Manitoba, Canada

The purpose of this paper is to provide a comparative analysis of pork value chains in Catalonia, Spain and Manitoba, Canada. Intensive hog production models were implemented in Catalonia in the 1960s as a result of agriculture crises and fostered by feedstuffs factories. The expansion of the hog sector in Manitoba is more recent (in the 1990s) and brought about in large part by the opening of the Maple Leaf Meats processing plant in Brandon, Manitoba. This plant is capable of processing 90,000 hogs per week. Both hog production models ‐ the ‘older’ one in Catalonia (Spain) and the ‘newer’ in Manitoba‐ have been, until recently, examples of success. Inventories and production have been increasing substantially and both regions have proven to have great export potential. Recently, however, tensions have been developing with the hog production models of both regions, particularly as they relate to environmental concerns. The purpose of the paper is to compare the value chains with respect to their origins (e.g. supply a growing demand for pork, ensure farm profitability) and present states (e.g. environmental concerns, profitability). Keywords: pork value chain, hog farms, agri‐food studies. JEL: Q10, Q13, O57
