Looking for orders of magnitude : five essays in trade and the environment and economic geography

General Summary Although the chapters of this thesis address a variety of issues, the principal aim is common: test economic ideas in an international economic context. The intention has been to supply empirical findings using the largest suitable data sets and making use of the most appropriate empirical techniques. This thesis can roughly be divided into two parts: the first one, corresponding to the first two chapters, investigates the link between trade and the environment, the second one, the last three chapters, is related to economic geography issues. Environmental problems are omnipresent in the daily press nowadays and one of the arguments put forward is that globalisation causes severe environmental problems through the reallocation of investments and production to countries with less stringent environmental regulations. A measure of the amplitude of this undesirable effect is provided in the first part. The third and the fourth chapters explore the productivity effects of agglomeration. The computed spillover effects between different sectors indicate how cluster-formation might be productivity enhancing. The last chapter is not about how to better understand the world but how to measure it and it was just a great pleasure to work on it. "The Economist" writes every week about the impressive population and economic growth observed in China and India, and everybody agrees that the world's center of gravity has shifted. But by how much and how fast did it shift? An answer is given in the last part, which proposes a global measure for the location of world production and allows to visualize our results in Google Earth. A short summary of each of the five chapters is provided below. The first chapter, entitled "Unraveling the World-Wide Pollution-Haven Effect" investigates the relative strength of the pollution haven effect (PH, comparative advantage in dirty products due to differences in environmental regulation) and the factor endowment effect (FE, comparative advantage in dirty, capital intensive products due to differences in endowments). We compute the pollution content of imports using the IPPS coefficients (for three pollutants, namely biological oxygen demand, sulphur dioxide and toxic pollution intensity for all manufacturing sectors) provided by the World Bank and use a gravity-type framework to isolate the two above mentioned effects. Our study covers 48 countries that can be classified into 29 Southern and 19 Northern countries and uses the lead content of gasoline as proxy for environmental stringency. For North-South trade we find significant PH and FE effects going in the expected, opposite directions and being of similar magnitude. However, when looking at world trade, the effects become very small because of the high North-North trade share, where we have no a priori expectations about the signs of these effects. Therefore popular fears about the trade effects of differences in environmental regulations might by exaggerated. The second chapter is entitled "Is trade bad for the Environment? Decomposing worldwide SO2 emissions, 1990-2000". First we construct a novel and large database containing reasonable estimates of SO2 emission intensities per unit labor that vary across countries, periods and manufacturing sectors. Then we use these original data (covering 31 developed and 31 developing countries) to decompose the worldwide SO2 emissions into the three well known dynamic effects (scale, technique and composition effect). We find that the positive scale (+9,5%) and the negative technique (-12.5%) effect are the main driving forces of emission changes. Composition effects between countries and sectors are smaller, both negative and of similar magnitude (-3.5% each). Given that trade matters via the composition effects this means that trade reduces total emissions. We next construct, in a first experiment, a hypothetical world where no trade happens, i.e. each country produces its imports at home and does no longer produce its exports. The difference between the actual and this no-trade world allows us (under the omission of price effects) to compute a static first-order trade effect. The latter now increases total world emissions because it allows, on average, dirty countries to specialize in dirty products. However, this effect is smaller (3.5%) in 2000 than in 1990 (10%), in line with the negative dynamic composition effect identified in the previous exercise. We then propose a second experiment, comparing effective emissions with the maximum or minimum possible level of SO2 emissions. These hypothetical levels of emissions are obtained by reallocating labour accordingly across sectors within each country (under the country-employment and the world industry-production constraints). Using linear programming techniques, we show that emissions are reduced by 90% with respect to the worst case, but that they could still be reduced further by another 80% if emissions were to be minimized. The findings from this chapter go together with those from chapter one in the sense that trade-induced composition effect do not seem to be the main source of pollution, at least in the recent past. Going now to the economic geography part of this thesis, the third chapter, entitled "A Dynamic Model with Sectoral Agglomeration Effects" consists of a short note that derives the theoretical model estimated in the fourth chapter. The derivation is directly based on the multi-regional framework by Ciccone (2002) but extends it in order to include sectoral disaggregation and a temporal dimension. This allows us formally to write present productivity as a function of past productivity and other contemporaneous and past control variables. The fourth chapter entitled "Sectoral Agglomeration Effects in a Panel of European Regions" takes the final equation derived in chapter three to the data. We investigate the empirical link between density and labour productivity based on regional data (245 NUTS-2 regions over the period 1980-2003). Using dynamic panel techniques allows us to control for the possible endogeneity of density and for region specific effects. We find a positive long run elasticity of density with respect to labour productivity of about 13%. When using data at the sectoral level it seems that positive cross-sector and negative own-sector externalities are present in manufacturing while financial services display strong positive own-sector effects. The fifth and last chapter entitled "Is the World's Economic Center of Gravity Already in Asia?" computes the world economic, demographic and geographic center of gravity for 1975-2004 and compares them. Based on data for the largest cities in the world and using the physical concept of center of mass, we find that the world's economic center of gravity is still located in Europe, even though there is a clear shift towards Asia. To sum up, this thesis makes three main contributions. First, it provides new estimates of orders of magnitudes for the role of trade in the globalisation and environment debate. Second, it computes reliable and disaggregated elasticities for the effect of density on labour productivity in European regions. Third, it allows us, in a geometrically rigorous way, to track the path of the world's economic center of gravity.

La passió segons Renée Vivien i el miratge-miracle del mirall

In this article, Rosa Cabré discusses Marçal¿s novel and illustrates how, according to the author, the desire of love, which is a source of pleasure often accompanied by guilt and distress, can lead to the creation or the illusion of an absolute beauty, like poetry. She explains in what way the mirror and the mask, recurring motifs in Marçal¿s work, symbolise identity and ¿otherness¿ and how these unite the real and the symbolic level. The novel contains an infinite number of mirrors, both external and internal ones, which enable the characters to see themselves reflected. This reflection is linked to feminity and to the possibilities of discovering one¿s own identity.

El consum de drogues i cocaïna dels joves de l’IES Miquel Martí i Pol de Roda de Ter

En l’actualitat, l’ús i el consum de substàncies il·legals pels joves de l’IES Miquel Martí i Pol de Roda de Ter és un fenomen associat a l’oci, per tant es tracta d’un consum recreatiu per fer referència al consum que fan els joves que el que busquen és diversió i plaer, moltes vegades, sense percebre’n el risc. Pel que fa a les drogues legals, alcohol i tabac són les substàncies psicoactives de major consum. La cocaïna és pels joves la segona substància consumida, rere el cànnabis, que és la més estesa entre la població adolescent i joves de l’IES. Es pot dir que existeixen una sèrie de situacions de caràcter personal i social que poden predisposar certes persones a consumir drogues. Aquestes circumstàncies són els anomenats factors de risc, com són l’autoestima, absència de normes i límits, manca d’informació, manca de comunicació, entre d’altres. També hi ha d’altres situacions socioculturals i característiques individuals que fan que se’n redueixi la possibilitat de consum, aquests serien els anomenats factors de protecció com són l’economia, tenir aficions, disposar d’adults de referència, etc. Conèixer i comprendre aquests factors és fonamental per poder realitzar un abordatge educatiu i preventiu basat en la reducció de riscos i en la responsabilitat i l’autonomia de les persones usuàries de drogues.

Obrim la biblioteca : fem bibliopati !

Aquest treball pretén analitzar la importància de la lectura a l’escola tot posant èmfasi en el fet de llegir per plaer. Partint d’una base teòrica que ho fonamenti s’ha realitzat i analitzat una experiència innovadora: un bibliopati. Durant quatre sessions la biblioteca ha tret una part dels seus materials a fora el pati, de manera que han sigut els llibres qui han anat a buscar els alumnes i no al revés. Aquesta activitat, totalment voluntària, pretenia fomentar l’hàbit lector i donar a conèixer el potencial que té la biblioteca escolar.

Lorsque le patient obèse ne perd pas de poids ou continue a en prendre... [When the obese patient can't lose any weight or keeps putting some on].

The traditional obesity treatments have proven to be ineffective in the long-term. The presence of eating disorders frequently explains this phenomena. Eating educational and behavioral aspects must be addressed in a practical way so that patients could gradually become aware of their behavior towards food as well as internal sensations associated with hunger, satiety, craving and pleasure. Finally, the link between emotions and compulsive eating behaviors during and between meals is an essential aspect that the general practitioner can help the patient to understand. A specialized psychological treatment can then be considered when the patient shows sufficient motivation and consciousness.

Concentrative nucleoside transporter 1 (hCNT1) promotes phenotypic changes relevant to tumor biology in a translocation independent manner

Nucleoside transporters (NTs) mediate the uptake of nucleosides and nucleobases across the plasma membrane, mostly for salvage purposes. The canonical NTs belong to two gene families, SLC29 and SLC28. The former encode equilibrative nucleoside transporter proteins (ENTs), which mediate the facilitative diffusion of natural nucleosides with broad selectivity, whereas the latter encode concentrative nucleoside transporters (CNTs), which are sodium-coupled and show high affinity for substrates with variable selectivity. These proteins are expressed in most cell types, exhibiting apparent functional redundancy. This might indicate that CNTs play specific roles in the physiology of the cell beyond nucleoside salvage. Here, we addressed this possibility using adenoviral vectors to restore tumor cell expression of hCNT1 or a polymorphic variant (hCNT1S546P) lacking nucleoside translocation ability. We found that hCNT1 restoration in pancreatic cancer cells significantly altered cell-cycle progression and phosphorylation status of key signal-transducing kinases, promoted poly-(ADP ribose) polymerase hyperactivation and cell death, and reduced tumor growth and cell migration. Importantly, the translocation-defective transporter triggered these same effects on cell physiology. These data predict a novel and totally unexpected biological role for the nucleoside transporter protein hCNT1 that appears to be independent of its role as mediator of nucleoside uptake by cells, thereby suggesting a transceptor function.

Carme Serrallonga, el plaer de traduir

Carme Serrallonga (Barcelona, 1909-1997) començà a traduir als anys seixanta, en moments de represa de consciència ideològica i literària. Bona coneixedora de diversos idiomes, especialment l’alemany, l’anglès, el francès i l’italià, girà al català unes vint obres del teatre universal dels grans autors. Serrallonga explicava que havia començat a aprendre alemany per poder conèixer a fons l’obra de Brecht, del qual el 1966 traduí La bona persona de Sezuan, a proposta de Ricard Salvat, i cinc obres més. De l’alemany també portà al català autors com Georg Büchner, Heinrich Böll, Friedrich Dürrenmatt, Peter Handke, György Lukács, Goethe, Mozart o Alfred Döblin. A més de l’alta literatura alemanya, Serrallonga féu petites incursions en la literatura anglesa i nord-americana, la italiana i, fins i tot, la sud-africana. El 1983 l’editorial La Galera li encarregà la traducció d’En Jim Botó i en Lluc el maquinista de Michael Ende. En sis anys traduí més de trenta títols de literatura infantil. Ja jubilada, a vuitanta-quatre anys, es posà a estudiar rus pel plaer de poder llegir Anna Akhmàtova i Txèkhov en la seva llengua originària. Abans de morir, treballava en la traducció d’un llibre de poemes de l’autora russa.

Budjettitaloudesta ansaintatalouteen – muutosjohtamisen haasteet Tieliikelaitoksessa

Tutkielman tavoite: Tutkielman tavoitteena on kuvata ja arvioida erään organisaation muutosprosessia, jonka seurauksena virastomallista organisaatiota ollaan muuttamassa paremmin kilpailuille markkinoille sopivaan liikelaitosmuotoon. Tutkielmassa selvitetään, miten siirtyminen budjettitaloudesta ansaintatalouteen vaikuttaa tutkittavan organisaation johtamiseen, henkilöstön asenteisiin ja työtapoihin sekä koko organisaation toimivuuteen. Tutkielman ongelma on muotoiltu seuraavasti: Mikä motivoi ja sitouttaa virastoaikana työssä ollutta henkilöstöä muutokseen, jossa ”turvallisesta” virastomallista ollaan siirtymässä asteittain kilpailtujen markkinoiden epävarmuuteen? Tutkimusmenetelmä: Tutkielman tutkimusstrategiaksi valittiin kvantitatiivinen survey –tutkimus ja aineistonkeruumenetelmäksi lomakekysely. Tutkielman teoreettinen viitekehys muodostuu aikaisemmista tutkimuksista, jotka käsittelevät: muutoksen vaikutuksia liiketoimintaan, muutokseen sitoutumisista, muutoksen johtamista, yksilön asemaa muutoksessa sekä muutosta julkisella sektorilla. Tutkielman tulokset ja johtopäätökset: Tutkittavan organisaation virastoaikainen henkilöstö on tämän tutkielman perusteella erittäin sitoutunut organisaatioonsa ja erittäin motivoitunut tekemään työtä organisaation menestyksen eteen myös tulevaisuudessa. Eniten virastoaikaista henkilöstöä motivoi tekemään työtä uusissa olosuhteissa mahdollisuus oppia uusia asioita sekä onnistuneesti tehdyn työn tuottama hyvän olon tunne. Tutkielmassa myös selvisi, että organisaatioon sitoutumisen aste sekä suhtautuminen muutokseen ovat suoraan verrannollisia organisaatioasemaan. Mitä korkeammassa asemassa henkilö organisaatiossa on, sitä sitoutuneempi hän organisaatioon on ja sitä positiivisemmin hän muutokseen suhtautuu. Organisaatiomuutos on tutkittavassa organisaatiossa ollut vaikea prosessi ja se on vaikuttanut jokaiseen organisaation yksilöön. Henkilöstön työmäärä, vaatimukset työtä kohtaan, sisäinen kilpailu, kiire ja näistä kaikista johtuen myös stressi ovat lisääntyneet virastoajasta. Myös henkilöstöresursseja on muutoksen seurauksena jouduttu karsimaan. Kokonaisuudessaan organisaatiomuutos on henkilöstön mielestä ollut melko positiivinen asia ja sen on nähty parantaneen organisaation toiminnan tehokkuutta.

Analysis of the process of inspection in recreational craft in Spain. Suggestions for safety improvement

Inspections of pleasure boats in Spain can be carried out by collaborating entities of inspection, entities that must be authorized by the Maritime Administration. This authorization allows to perform effective inspections and technical controls of recreational crafts. Recreational crafts are subjected to surveys that are based on the registration list and on the material used in the hull. In addition, required safety equipment of the recreational boat depends on the distance that the recreational boat is authorized to navigate. Following data obtained from inspections of recreational craft, this paper aims to analyze information about hulls within dry and afloat conditions, about the equipment for rescue and safety, and about other nautical equipment; as well as to perform and improve different verifications during the inspections. All this information points to several aspects relevant for the optimization of the inspection process, the ultimate target being increasing efficiency and effectiveness, and ensuring more safety in recreational craft.

Greek de Steven Berkoff (1980): L’arriscada conversió de l’Èdip rei de Sòfocles en una love story

[cat] ¿Podem convertir l’Èdip rei de Sòfocles en una història d’amor com ho fa Berkoff a Greek?. Tot i que alguns crítics llegeixen Greek només com un drama provocador que de cap manera intenta justificar l’incest, directors, actors i crítics resten finalment captivats per la impactant història d’amor entre Eddy i la seva esposa-mare. Això demostraria que l’adaptació de Berkoff, pensada per a il·lustrar la degradació social de la Gran Bretanya dels 80s, esdevé una proposta arriscada, car significa negar de fet la consciència tràgica dels homes i dones contemporanis. Tanmateix, si aquest és el cas, lectors i espectadors, a banda de l’indubtable plaer d’assistir a la representació de Greek, poden preguntar-se, fins i tot des d’una perspectiva no fonamentalista de la tradició clàssica, si té sentit inspirar-se en el text de Sòfocles, el qual mostra precisament la gran consciència tràgica dels grecs.
