Interplays Between Corporate Reputation And Media – A Bibliometric Analysis
2020
Abstract As strategic asset – determinant of sustained competitiveness – corporate/firm reputation has a very distinctive feature that sets it apart: although reflection of (better, worse or not at all performed) reputation management at a company’s level, it is rather a “representation” / “perception” – built on a business’s previous behaviors, but more precisely on the ways its different stakeholders have interacted (acknowledged, internalized, resonated) with them – in a (sometimes unconscious) process highly mediated and moderated by the media. Thus, the current study aims to explore the interplays between corporate/firm reputation and media as they are reflected in the scientific liter…
Forecast Output Coincidence and Biproportion: Two Criteria to Determine the Orientation of an Economy. Comparison for France (1980-1997)
2002
International audience; The method of forecast output coincidence used to determine if sectors are demand-sided or supply-sided in an input-output framework mixes two effects, the structural effect (choosing between demand and supply side models) and the effect of an exogenous factor (final demand or added-value). The note recalls that another method is possible, the comparison of the stability of technical and allocation coefficients, generalized by the biproportional filter: if for a sector, after biproportional filtering, column coefficients are more stable than row coefficients, then this sector is declared as not supply-sided (but one cannot decide that it is demand-sided anyway), and …
A comparative life-cycle assessment of asphalt mixtures for railway sub-ballast containing alternative materials
2018
Abstract Bituminous sub-ballast in railway track-bed can mitigate the variation of the moisture content in the subgrade and reduce vertical stiffness variations of the track leading to a more durable infrastructure. Nevertheless, durability is only one of the aspects that affects the sustainability of an infrastructure. Other relevant aspects are related to the environmental and economic issues. This research work joins the worldwide effort towards a paradigm shift in civil engineering devoted to assess the sustainability of infrastructures at the design stage. With this in mind, in this study different alternative bituminous sub-ballast mixtures containing recycled materials, namely crumb …
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…
The Border Effect in Spain
2005
This paper analyses the border effect in Spain using a unique dataset on intranational trade flows over the period 1995–98. The results indicate that, after controlling for market size and distance, Spanish regions trade around 22 times more with the rest of Spain than they do with OECD countries. Moreover, the size of the Spanish bias is lower in the case of the Spanish regions’ exports than in the case of imports, although the difference is not statistically significant in most cases. Finally, the border effect is not uniform across Spanish regions.
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…
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…
Efectos del desarrollo sostenible percibido por el consumidor. Una propuesta de modelo de hipermercados en Ecuador
2020
Resumen El objetivo de este trabajo fue analizar la incidencia del desarrollo sostenible sobre la cadena de efectos: valor percibido - capital de marca - lealtad. Para ello, se propone un modelo teórico de relaciones que se contrasta a partir de una muestra de 317 clientes de hiper mercados en Ecuador. Los resultados, aplicando una metodología exploratoria y confirmatoria, combinada con regresión por mínimos cuadrados parciales, mostraron que tanto las acciones de desarrollo sostenible como el valor percibido son pilares maestros sobre los que se puede apoyar la estrategia minorista. Ambas se muestran como variables clave por su naturaleza, en cuanto son multidimensio nales, y por su alcanc…
Executive remuneration determinants: New evidence from meta-analysis
2019
This meta-analysis takes stock of 121 C.E.O. pay studies published between 1998 and 2018 with the objective of identifying the main drivers of C.E.O. pay from a global perspective and contributing to the agency vs managerial debate on this ground. The meta-results disclose a positive C.E.O. pay–performance correlation (the highest correlation coefficient corresponds to Earnings per share with a 34%) as the agency theory prescribes and the governance policies promote. However, firm size still predominates as the main driver of C.E.O. pay (correlation coefficient is around 44%) according to managerial premises. Moreover, our results reconcile both approaches because results of the meta-regres…
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…
