Territorial tripolarization in Bolivia : genesis and current situation

2012

The Bolivian urban system is outstanding : three major cities concentrate about half of the nation’s population and employment. Their territories’ trajectories lead us to question their economic role in the face of the successful economic achievement of Potosi and Tarija, territories well endowed in natural resources. We wanted to highlight the Bolivian current territorial tripolarization, firstly by studying its emergence, through the study of their economical history; secondly, by investigating the most recent economical data in order to display the strengths and weaknesses of this tripolarized system. Each component of the tripole is situated in a different geographical setting. In the W…

The Bologna Process in France : Origin, Objectives and Implementation

2008

05010; In this paper, we will try to show why the evolution of the French higher education system has led to a deadlock and a deteriorating ranking on the world scene, how the new scheme has been effectively and rapidly adopted, but unfortunately, why this adoption has failed to achieve the initial objectives of transforming the French system into a more competitive one.

Emergence of statistically validated financial intraday lead-lag relationships

2014

According to the leading models in modern finance, the presence of intraday lead-lag relationships between financial assets is negligible in efficient markets. With the advance of technology, however, markets have become more sophisticated. To determine whether this has resulted in an improved market efficiency, we investigate whether statistically significant lagged correlation relationships exist in financial markets. We introduce a numerical method to statistically validate links in correlation-based networks, and employ our method to study lagged correlation networks of equity returns in financial markets. Crucially, our statistical validation of lead-lag relationships accounts for mult…

Is the Border Effect an Artefact of Geographical Aggregation?

2011

The existence of a large border effect is considered as one of the main puzzles of international macroeconomics. We show that the border effect is, to a large extent, an artefact of geographic concentration. In order to do so we combine international flows with intra-national flows data characterised by a high geographic grid. At this fine grid, intra-national flows are highly localised and dropping sharply with distance. The use of a small geographical unit of reference to measure intra-national bilateral trade flows allows to estimating correctly the negative impact of distance on shipments. When we use sector disaggregated export flows of 50 Spanish provinces in years 2000 and 2005 split…

Éléments de réflexion sur les impacts économiques du réchauffement climatique sur la filière vitivinicole en Bourgogne.

2007

Actes:CD-Rom et en ligne sur http://www.u-bourgogne.fr/chaireunesco-vinetculture/Actes%20clima/Actes/Actes.htm; Les différentes conséquences des modifications climatiques ont des aspectséconomiques sur la filière vitivinicole particulièrement complexes et extrêmement variablesselon les régions et les vignobles à travers le monde. En Bourgogne, quatre cépages (aligoté,chardonnay, gamay, pinot noir essentiellement), aux réactions spécifiques, sontparticulièrement concernés.La difficulté de l'analyse (puis de l'évaluation dans une étape ultérieure) tient àl'existence d'une multitude de situations spécifiques que l'on se propose de commencer àcaractériser ici.

On site consolidation of burnt and partially charred wood in dry conditions

2011

Abstract Forty years ago in a xx th-century church in Torino, a small fire partially burned some of the decorative external boards of the sound-box of the organ. The focus of this present work was to find a treatment able to consolidate partially burnt wood in dry conditions, in which the external charred layer would be lost if not well preserved because of its incoherence. The product had to be applied onsite on an architectural structure intended to be reused again (and not simply exhibited). This circumstance is rarely encountered in the conservation of wooden Cultural Heritage. The efficacy of treatments was evaluated on the basis of a suitable and original experimental methodology, whi…

How credit ratings affect sovereign credit risk: cross-border evidence in Latin American emerging markets

2017

This article builds upon previous literature by providing a better understanding of how contagion changes in bordering sovereign CDS emerging markets resulting from credit rating events. To that end, we follow the novel GVAR methodology using data from six Latin American emerging countries during an extensive sample period from 2004 to 2014. Our findings show evidence for the existence of significant and asymmetric cross-border effects. In particular, a competition effect is observed before the event occurs, indicating that non-event countries suffer (benefit) from upgrades (downgrades) in Brazil, Mexico and Chile (in Argentina and Brazil). In contrast, an imitation effect is observed after…
