Spinning welfare: The gains from process innovation in cotton and car production

Economists and economic historians want to know how much better life is today than in the past.Fifty years ago economic historians found surprisingly small gains from 19th century US railroads,while more recently economists have found relatively large gains from electricity, computers and cellphones. In each case the implicit or explicit assumption is that researchers were measuring the valueof a new good to society. In this paper we use the same techniques to find the value to society ofmaking existing goods cheaper. Henry Ford did not invent the car, and the inventors of mechanisedcotton spinning in the industrial revolution invented no new product. But both made existing productsdramatically cheaper, bringing them into the reach of many more consumers. That in turn haspotentially large welfare effects. We find that the consumer surplus of Henry Ford s production linewas around 2% by 1923, 15 years after Ford began to implement the moving assembly line, while themechanisation of cotton spinning was worth around 6% by 1820, 34 years after its initial invention.Both are large: of the same order of magnitude as consumer expenditure on these items, and as largeor larger than the value of the internet to consumers. On the social savings measure traditionally usedby economic historians, these process innovations were worth 15% and 18% respectively, makingthem more important than railroads. Our results remind us that process innovations can be at least asimportant for welfare and productivity as the invention of new products.

Subcontracting and vertical integration in the Spanish cotton industry

This paper examines changes in the organization of the Spanish cotton industry from 1720 to 1860 in its core region of Catalonia. As the Spanish cotton industry adopted the most modern technology and experienced the transition to the factory system, cotton spinning and weaving mills became increasingly vertically integrated. Asset specificity more than other factors explained this tendency towards vertical integration. The probability for a firm of being vertically integrated was higher among firms located in districts with high concentration ratios and rose with size and the use of modern machinery. Simultaneously, subcontracting predominated in other phases of production and distribution where transaction costs appears to be less important.

Labour market in the Catalan cotton textile sector: Employment and fertility (1850-1913)

This paper deals whit the dynamics of the Catalan textile labour market (theSpanish region that concentrated most of the industrial and factory activity duringthe 19 Century) and offers hypotheses and results on the impact it had on livingstandards and fertility levels. We observe the formation of an uneven labourmarket in which male supply for labour (excluding women and children) grewmuch faster than the demand. We stress the fact that labour supply is verydependant on institutional factors liked to the transmition of household propertybetween generations. Instead the slow path of growth of adult males demand forlabour is witnessing the limits of this industry to expand and to compete ininternational markets. The strategy of working class families to adapt to scarceopportunities of employment we document here is the diminution of legitimatefertility levels. Fertility control is the direct instrument we think workers have tocontrol their number in a situation that was likely to create labour surpluses in theshort and mid run.

Vertical integration or specialisation: producing and commercialising cotton goods (1815-1913)

This article describes the ways in which cotton goods were commercialised during the nineteenth century and the first third of the twentieth. Several national cases are analysed: Britain, as the Workshop of the World; France, Germany, Switzerland and the US, as core economies; and Italy and Spain as countries on the European periphery. The main question that we address is why some cotton industries vertically integrated their production and commercialisation processes, but others did not. We present a model that combines industrial district size and product differentiation to explain why vertical integration was present in most cases and why there was vertical specialisation in Lancashire and Lowell.

Cotton manufacturers as bankers: the textile trade and credit in spain, 1840-1913

[cat] La historiografia ha assenyalat que en el segle XIX el crèdit que els fabricants cotoners catalans oferien als seus clients era de caràcter informal i, per tant, impossible de ser transferit al sistema bancari. Això hauria tingut un efecte negatiu en la rendibilitat de les empreses cotoneres. A partir de l’anàlisi de diversos arxius empresarials, així com de fonts judicials i notarials, aquest treball confirma aquesta descripció dels fets però proposa una interpretació més optimista. Els fabricants feien de banquers dels seus clients perquè eren els millor situats per a exercir aquesta funció. Havien construït una bona estructura d’informació, gestionaven eficientment el risc creditici i obtenien beneficis d’aquesta activitat.

Degradation of pheromone and plant volatile components by a same Odorant-Degrading Enzyme in the cotton leafworm, Spodoptera littoralis

Background: Odorant-Degrading Enzymes (ODEs) are supposed to be involved in the signal inactivation step within the olfactory sensilla of insects by quickly removing odorant molecules from the vicinity of the olfactory receptors. Only three ODEs have been both identified at the molecular level and functionally characterized: two were specialized in the degradation of pheromone compounds and the last one was shown to degrade a plant odorant. Methodology: Previous work has shown that the antennae of the cotton leafworm Spodoptera littoralis , a worldwide pest of agricultural crops, express numerous candidate ODEs. We focused on an esterase overexpressed in males antennae, namely SlCXE7. We studied its expression patterns and tested its catalytic properties towards three odorants, i.e. the two female sex pheromone components and a green leaf volatile emitted by host plants. Conclusion: SlCXE7 expression was concomitant during development with male responsiveness to odorants and during adult scotophase with the period of male most active sexual behaviour. Furthermore, SlCXE7 transcription could be induced by male exposure to the main pheromone component, suggesting a role of Pheromone-Degrading Enzyme. Interestingly, recombinant SlCXE7 was able to efficiently hydrolyze the pheromone compounds but also the plant volatile, with a higher affinity for the pheromone than for the plant compound. In male antennae, SlCXE7 expression was associated with both long and short sensilla, tuned to sex pheromones or plant odours, respectively. Our results thus suggested that a same ODE could have a dual function depending of it sensillar localisation. Within the pheromone-sensitive sensilla, SlCXE7 may play a role in pheromone signal termination and in reduction of odorant background noise, whereas it could be involved in plant odorant inactivation within the short sensilla.

La formació d'una política exterior per a l'Índia. La visita de Nehru a l'Espanya republicana durant la Guerra Civil

L'objectiu ha estat posar en relació dues realitats que fins al moment havien estat considerades completament alienes, com són l’Índia i Espanya. La recerca de fonts per a les relacions bilaterals de tot tipus es va iniciar al segle XIX. A partir d’aquest moment apareixen tres camps fonamentals on aprofundir. D’una banda tenim les relacions diplomàtiques i la seva vessant política a partir del segle XX. El desenvolupament de representacions consulars té a veure amb el creixement de l’activitat econòmica amb l’Índia britànica, especialment en el camp del proveïment de primeres matèries (cotó i jute). En aquest sentit, la recuperació de les relacions econòmiques va ser clau per al posterior mutu reconeixement diplomàtic el 1957 quan l’Índia ja era un estat independent. Entre mig queden anys de malvolença degut a la vinculació de Nehru amb el govern republicà durant la Guerra Civil i la posició de l’Índia en el cas d’Espanya a l’ONU. Un altre camp d’interès per a les relacions bilaterals es centra en la missió de Bombay que a partir de 1920 fou administrada per jesuïtes catalans, valencians i aragonesos. Finalment, un seguiment de la premsa i la intel•lectualitat espanyola mostra com l’Índia es va convertir a partir de 1920 en un nou focus d’interès informatiu i pel món acadèmic, com no ho havia estat fins llavors. Aquest descobriment de l’Índia per part de viatgers, artistes i periodistes obra una nova via d’intercanvi que es veurà trucada per la Guerra Civil i el posterior establiment d’un règim que destruí el teixit intel•lectual del país.

How The 1996 Hotel Majestic agreement may explain a future PP/CiU relationship in Madrid

Some historians have argued that 1996 marked a ‘second transition’ for Spain because of the return to power of the political right in Madrid and that the relationship and eventual pact between the Partido Popular (PP) and Convergència i Unió (CiU) meant that the state could finally escape the ghosts of its Francoist past. For this research, face-to-face interviews were conducted with Catalan Members of Parliament who served under either José María Aznar or Jordi Pujol in Madrid or Barcelona. Drawing upon both interviews and other evidence, including the analysis of election results and the 1996 Hotel Majestic Agreement, the research seeks to provide a better understanding of the previous relationships between the PP and CiU and their leaders in order to understand what lessons might be learnt that would contribute to anticipating and explaining possible future negotiations between the two parties. This is attempted by first examining the potential costs and benefits of political pacts between centre (Madrid) and periphery (Barcelona). Secondly, due to many interviewees making reference to Salvador Espriu’s work La Pell de Brau, the three routes of Espriu’s Catalan nationalism are put into the context of the political pacts. Finally, the likelihood of future agreements between PP and CiU are hypothesized, not only how those agreements may (or may not) come about, but also, what might the result of those negotiations be. Ultimately, it is concluded that the benefits of the Hotel Majestic Agreement outweighed the costs, thus leaving the door open for future negotiations, even if some of those interviewed disagreed.

Fabricants, comerciants i banquers. Les estructures comercials de la indústria cotonera catalana en el mercat español (1840-1936)

Aquesta tesi analitza la integració vertical entre fabricació, comercialització i finançament a la indústria catalana del període 1840-1936. L¿evidència obtinguda de les fonts arxivístiques confirma la visió tradicional quant a la descripció dels fets, però ofereix una interpretació alternativa, més optimista, de les causes i de les conseqüències. Els fabricants s¿implicaren en la comercialització perquè ells eren els coordinadors entre oferta i demanda (no com en el cas britànic, on ho eren els comerciants), i per tant havien de tenir un peu a cada banda. A més, els fabricants eren els més ben situats per a ser uns banquers eficients dels seus clients.
