Globalization, technology and inequality

What are the effects of international integration on inequality, both between and within countries? The growing evidence that technology is the main determinant of wage and income differences may seem to imply that the forces of globalization only play a secondary role. Such a conclusion is however premature, in that it neglects the effect of international integration on technology itself. This opuscle summarizes recent and ongoing research studying how two important aspects of globalization, trade in goods and offshoring of production, shape the distribution of income when technological progress is endogenous. It discusses the theoretical foundations and the empirical support for various mechanisms through which international integration may change the incentive to develop and adopt new technologies and how this affects wages and the return to skill around the world.

Judges' cognition and market order

We argue that during the crystallization of common and civil law in the 19th century, the optimal degree of discretion in judicial rulemaking, albeit influenced by the comparative advantages of both legislative and judicial rulemaking, was mainly determined by the anti-market biases of the judiciary. The different degrees of judicial discretion adopted in both legal traditions were thus optimally adapted to different circumstances, mainly rooted in the unique, market-friendly, evolutionary transition enjoyed by English common law as opposed to the revolutionary environment of the civil law. On the Continent, constraining judicial discretion was essential for enforcing freedom of contract and establishing a market economy. The ongoing debasement of pro-market fundamentals in both branches of the Western legal system is explained from this perspective as a consequence of increased perceptions of exogenous risks and changes in the political system, which favored the adoption of sharing solutions and removed the cognitive advantage of parliaments and political leaders.

Stakeholder activism, managerial entrenchment and the congruence of interests between shareholders and stakeholders

We argue that when stakeholder protection is left to the voluntaryinitiative of managers, concessions to social activists and pressuregroups can turn into a self-entrenchment strategy for incumbent CEOs.Stakeholders other than shareholders thus benefit from corporategovernance rules putting managers under a tough replacement threat. Weshow that a minimal amount of formal stakeholder protection, or the introduction of explicit covenants protecting stakeholder rights in thefirm charter, may deprive CEOs of the alliance with powerful socialactivists, thus increasing managerial turnover and shareholder value.These results rationalize a recent trend whereby well-known socialactivists like Friends of the Earth and active shareholders likeCalPERS are showing a growing support for each other s agendas.

High amplitude contractions in the middle third of the esophagus: a manometric marker of chronic alcoholism?

BACKGROUND--Oesophageal motor abnormalities have been reported in alcoholism. AIM--To investigate the effects of chronic alcoholism and its withdrawal on oesophageal disease. PATIENTS--23 chronic alcoholic patients (20 men and three women; mean age 43, range 23 to 54). METHODS--Endoscopy, manometry, and 24 hour pH monitoring 7-10 days and six months after ethanol withdrawal. Tests for autonomic and peripheral neuropathy were also performed. Motility and pH tracings were compared with those of age and sex matched control groups: healthy volunteers, nutcracker oesophagus, and gastro-oesophageal reflux disease. RESULTS--14 (61%) alcoholic patients had reflux symptoms, and endoscopy with biopsy showed oesophageal inflammation in 10 patients. One patient had an asymptomatic squamous cell carcinoma. Oesophageal motility studies in the alcoholic patients showed that peristaltic amplitude in the middle third was > 150 mm Hg (95th percentile (P95) of healthy controls) in 13 (57%), the ratio lower/ middle amplitude was < 0.9 in 15 (65%) (> 0.9 in all control groups), and the lower oesophageal sphincter was hypertensive (> 23.4 mm Hg, P95 of healthy controls) in 13 (57%). All three abnormalities were present in five (22%). Abnormal reflux (per cent reflux time > 2.9, P95 of healthy controls) was shown in 12 (52%) alcoholic patients, and was unrelated to peristaltic dysfunction. Subclinical neuropathy in 10 patients did not effect oesophageal abnormalities. Oesophageal motility abnormalities persisted at six months in six patients with ongoing alcoholism, whereas they reverted towards normal in 13 who remained abstinent; reflux, however, was unaffected. CONCLUSIONS--Oesophageal peristaltic dysfunction and reflux are frequent in alcoholism. High amplitude contractions in the middle third of the oesophagus seem to be a marker of excessive alcohol consumption, and tend to improve with abstinence.

The First privatization : selling SOEs and privatizing public monopolies in fascist Italy, 1922-1925

[cat] El primer govern feixista d’Itàlia va aplicar una política de privatització a gran escala entre 1922 i 1925. El govern va privatitzar el monopoli estatal de llumins, el monopoli estatal d’assegurances de vida, va vendre la major part de la xarxa i serveis de telefònica pública a empreses privades, va reprivatitzar el major productor de productes metàl·lics, i va atorgar concessions a empreses privades per construir i explotar autopistes de peatge. Tot i que algunes consideracions ideològiques van poder tenir alguna influència, la privatització va ser usada sobre tot com un instrument polític per construir confiança amb els grans industrials i per augmentar el suport al govern i al Partito Nazionale Fascista. La privatització també va contribuir a equilibrar el pressupost públic, qüestió aquesta que va ser el principal objectiu de la primera fase de la política econòmica feixista.

Evolutionary dynamics of molecular markers during local adaptation: a case study in Drosophila subobscura

Background: Natural selection and genetic drift are major forces responsible for temporal genetic changes in populations. Furthermore, these evolutionary forces may interact with each other. Here we study the impact of an ongoing adaptive process at the molecular genetic level by analyzing the temporal genetic changes throughout 40 generations of adaptation to a common laboratory environment. Specifically, genetic variability, population differentiation and demographic structure were compared in two replicated groups of Drosophila subobscura populations recently sampled from different wild sources. Results: We found evidence for a decline in genetic variability through time, along with an increase in genetic differentiation between all populations studied. The observed decline in genetic variability was higher during the first 14 generations of laboratory adaptation. The two groups of replicated populations showed overall similarity in variability patterns. Our results also revealed changing demographic structure of the populations during laboratory evolution, with lower effective population sizes in the early phase of the adaptive process. One of the ten microsatellites analyzed showed a clearly distinct temporal pattern of allele frequency change, suggesting the occurrence of positive selection affecting the region around that particular locus. Conclusion: Genetic drift was responsible for most of the divergence and loss of variability between and within replicates, with most changes occurring during the first generations of laboratory adaptation. We also found evidence suggesting a selective sweep, despite the low number of molecular markers analyzed. Overall, there was a similarity of evolutionary dynamics at the molecular level in our laboratory populations, despite distinct genetic backgrounds and some differences in phenotypic evolution.

Genome-wide DNA polymorphism analyses using VariScan

BACKGROUND: DNA sequence polymorphisms analysis can provide valuable information on the evolutionary forces shaping nucleotide variation, and provides an insight into the functional significance of genomic regions. The recent ongoing genome projects will radically improve our capabilities to detect specific genomic regions shaped by natural selection. Current available methods and software, however, are unsatisfactory for such genome-wide analysis. RESULTS: We have developed methods for the analysis of DNA sequence polymorphisms at the genome-wide scale. These methods, which have been tested on a coalescent-simulated and actual data files from mouse and human, have been implemented in the VariScan software package version 2.0. Additionally, we have also incorporated a graphical-user interface. The main features of this software are: i) exhaustive population-genetic analyses including those based on the coalescent theory; ii) analysis adapted to the shallow data generated by the high-throughput genome projects; iii) use of genome annotations to conduct a comprehensive analyses separately for different functional regions; iv) identification of relevant genomic regions by the sliding-window and wavelet-multiresolution approaches; v) visualization of the results integrated with current genome annotations in commonly available genome browsers. CONCLUSION: VariScan is a powerful and flexible suite of software for the analysis of DNA polymorphisms. The current version implements new algorithms, methods, and capabilities, providing an important tool for an exhaustive exploratory analysis of genome-wide DNA polymorphism data.

A study of the effects of PVAC on works of art on paper and wood: pH and colour change

This paper presents the preliminary findings of pH and colour measurements carried out on artworks on paperand on wood that had been treated with a poly(vinyl acetate) (PVAC) based adhesive in the 1980s. In both cases, areas treated with PVAC proved to be less acidic than untreated areas. Contrary to expectations, the conservation treatments have not, as yet, increased acidity levels in the objects under study. Colour measurements of the works on paper showed that those that had been backed with a cotton fabric using a mixture of methylcellulose and PVAC were less yellow than those from the same print run that had not been backed. This finding suggests that the backing somehow prevented the natural degradation of the support. In view of these preliminary results, further research is clearly needed. This study forms part of a broader ongoing project to assess the role of PVAC in the conservation of a range of cultural assets.

Catalan beauty and the transnational beast: Barcelona on screen

This article explores the case of Barcelona as paradigmatic global city in such transnational productions as Vicky Cristina Barcelona by Woody Allen (2008) and Biutiful by Alejandro González Iñárritu (2010). Allen"s film shows the extreme dilution that national and linguistic identity undergoes under foreign eyes in its rendition of a"hip Barcelona" for tourists"invaded" by transnational subjects in search of bourgeois pleasures. Maybe in pursuit of a more"real" city, Iñárritu"s Biutiful moves to the Barcelona of the immigrants and the undocumented, a transnational and paradoxical location inhabited by those who need to cross borders in order to survive. Through reference to the work of Manuel Castells, Saskia Sassen, Neil Smith and Michel De Certeau among others, we argue that neither of these representations of the city is more real or unreal than the other. In their drastically divergent ways, both films contribute their external perspectives to the imaginary construction of Barcelona as a fascinating global city and can be seen as a dyptich of a transnational Barcelona. Further, they contribute to the ongoing debate about the polarization between the local and the global, the construction of urban boarders inside cities through gentrification, the transformation of the places we (would like to) inhabit, and the translation of all these into visual terms.

Sectoral and occupational employment growth in Spain 1995-2005

Between 1995 and 2005, the Spanish economy grew at an annual average rate higher than 3,5%. Total employment increased by more than 4.9 millions. Most of this growth was in occupations related with university degrees (more than 890,000, 18% of the total employment increase) and vocational qualifications (more than 855,000, 17.5% of the total employment increase). From a sectoral perspective, the main part of this increase took place in “Real estate, renting and business activities” (K sector in NACE rev.1), “Construction” (F sector) and “Health and social sector” (N sector). This paper analyses this employment growth in an Input-output framework, by means of a structural decomposition analysis (SDA). Two kinds of results have been obtained. From a sectoral perspective we decompose employment growth into Labour requirements change, technical change and demand change. From an occupational perspective, we decompose the employment growth in substitutions effect, labour productivity effect and demand effect. The results show that, in aggregated terms, the main part of this growth is attributable to demand growth, with a small technical improvement. But the results also show that this aggregated behaviour hides important sectoral and occupational variation. The purpose of this paper is to contribute to the ongoing debate over productivity growth and what has been called the “growth model” for the Spanish economy.

El relato audiovisual publicitario del siglo XXI. Del medio televisión al medio internet. ¿Nuevos medios o nuevas formas de consumo audiovisual?

Estudiar la comunicación publicitaria del siglo XXI nos permite entender la importancia del desarrollo actual de este tipo de comunicación. Sin duda un desarrollo que afecta enormemente en el modo en que las marcas llevan a cabo sus estrategias de publicidad con su público. Pero sin duda el formato audiovisual sigue siendo el formato más utilizado por anunciantes y agencias para contactar con su público. El siglo XX estuvo definido por el desarrollo del medio televisión, el siglo XXI por el desarrollo del medio internet, pero la pregunta que realmente nos plantea este cambio mediático es conocer si estamos hablando de un cambio de medio o de un cambio en las estrategias y formatos publicitarios audiovisuales utilizados para llegar al receptor. Los mensajes publicitarios actuales resaltan por una mayor interactividad con el espectador, un contacto voluntario de éste, en muchos casos, con nuestra campaña e incluso una participación activa de nuestro consumidor en la distribución de la campaña. Los formatos evolucionan, también la relación del consumidor con el mensaje publicitario audiovisual y el producto

Predicting spinor condensate dynamics from simple principles

We study the spin dynamics of quasi-one-dimensional F=1 condensates both at zero and finite temperatures for arbitrary initial spin configurations. The rich dynamical evolution exhibited by these nonlinear systems is explained by surprisingly simple principles: minimization of energy at zero temperature and maximization of entropy at high temperature. Our analytical results for the homogeneous case are corroborated by numerical simulations for confined condensates in a wide variety of initial conditions. These predictions compare qualitatively well with recent experimental observations and can, therefore, serve as a guidance for ongoing experiments.
