Valuation effect of ESG and its impact on capital structure: Evidence from Europe
Full text linkIn this study, we examine the valuation effect of ESG performance using a sample of 895 European companies. The misvaluation of the company is determined by the ratio of its market price to its true value. A true value calculation is based on two measures: first, on the analysts' forecasted price, and second, on residual income. We find that improvements in ESG profiles increase market prices in relation to their true value. An analysis of overvalued and undervalued stocks separately revealed that ESG performance further enhances the existing level of overvaluation. Conversely, it restores undervalued stocks to their true value for residual income measures of misvaluation. Alternatively, mispricing measured by analysts' forecasted price is significant only for undervalued stocks and the entire sample. Our analysis suggests that information asymmetry and market sentiment play a moderating role in the ESG-misvaluation nexus, suggesting that ESG is a friction to market efficiency. ESG-related misvaluations further impact capital structure through market timing practices, and the increased stability of CSR can be attributed to a marginal increase in equity issuance. We attribute this valuation effect to the demand effect associated with ESG investments. The findings are robust to alternative measures of estimation
Le imprese del territorio e i parametri Environmental, Social and Governance: un’analisi sul portafoglio d’investimenti di Friulia S.p.A.
No full textLa regolamentazione di sostenibilità, a livello europeo, sta divenendo sempre più ampia e stringente. Se da un lato vi è la Corporate Sustainability Reporting Directive (CSRD) che impone obblighi di rendicontazione di sostenibilità alle grandi imprese (GI) e alle piccole e medie imprese (PMI) quotate in Borsa, dall’altro la Corporate Sustainability Due Diligence Directive (CSDDD) introduce obblighi di due diligence Environmental, Social and Governance (ESG) sulle catene di fornitura. La conseguenza pratica è che le PMI, apparentemente escluse dall’applicazione di questa regolamentazione (salvo se quotate), ne vengono interessate quando parte della catena del valore delle GI, soggette a regolamentazione. Al contempo, il Regolamento Sustainable Finance Disclosure Regulation (SFDR) e il Banking Book Taxonomy Alignment Ratio (BTAR) (che misura il livello di allineamento del portafoglio bancario alla tassonomia dell’Unione Europea) possono impattare sulla capacità delle PMI di ottenere credito, così come sul suo costo. È quindi evidente come le PMI saranno sempre più chiamate a confrontarsi con le pratiche ESG (salvo non si modifichi il contesto politico nel quale queste regole si sono sviluppate). Questa ricerca si è posta l’obiettivo di esplorare il livello di conoscenza e di “preparazione” delle PMI presenti nel portafoglio d’investimenti di Friulia S.p.A. finanziaria della Regione Friuli Venezia Giulia
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
