Liquidity pressure and the sovereign-bank diabolic loop
No full textWe study the sovereign-bank nexus through the liquidity channel. Using a sample of 22 European economies during 2012–2021, we find that an increase in banking liquidity pressures leads to a significant widening of SCDS spreads as banks are encouraged to purchase sovereign bonds for liquidity management purposes, consistent with the "flight to liquidity" phenomenon. This excessive exposure increases the probability of sovereign default in the long run by reducing the sustainability of sovereign debt and evoking a diabolic loop scenario. The results also suggest that ECB intervention can reinforce the feedback loop by lowering funding costs and triggering collateral trading
Do ESG strategies enhance bank stability during financial turmoil? Evidence from Europe
Full text linkThis paper investigates the joint and separate effects of Environmental (E), Social (S), and Governance (G) scores on bank stability. Using a sample of European banks operating in 21 countries over 2005–2017, we find that the total ESG score, as well as its sub-pillars, reduces bank fragility during periods of financial distress. This stabilizing effect holds strongly for banks with higher ESG ratings. These results are confirmed by a differences-in-differences (DID) analysis built around the introduction of the EU 2014 Non-Financial Reporting Directive (NFRD). Our evidence also reveals that, in times of financial turmoil, the longer the duration of ESG disclosures, the greater the benefits on stability. Finally, we show that the ESG–bank stability linkages vary significantly across banks’ characteristics and operating environments. Our findings are robust to selection bias and endogeneity concerns. Overall, they support the regulatory effort in requiring an enhanced disclosure of non–financial information

Are Islamic investments still safe assets during the COVID-19 pandemic?
No full textWhile looking for safe-haven assets, the literature obtained mixed and varying results, changing from one period to the next, or one geographical area to another. Recently, this field of research grew even more, motivated by the changing environment resulting from the global financial crisis and the current COVID-19 pandemic. We compare five Islamic and five conventional leading financial indexes for the period 2004–2020, covering both global and regional data (Asia-Pacific, Europe, GCC, and the United States). By employing DCC GARCH and extended GARCH (1,1) models, we find a lower volatility and higher persistence in Islamic indexes when compared to their conventional alternatives, holding also when traditional safe-haven assets are included in comparative terms and across geographical areas. We therefore provide robust evidence on the consistent behavior of Islamic assets: Their defensive properties remain and are even stronger in the current unprecedented and ongoing crisis
Mergers and acquisitions in the financial industry: A bibliometric review and future research directions
No full textThe growing application of bibliometric reviews in Finance, as well as the ongoing consolidation processes across firms and countries, motivated this study on mergers and acquisitions (M&A) in the Financial Industry. From a starting count of around 4500 papers, we refine our database accordingly to keywords and journal quality, reviewing a final sample of 174 papers. By combining bibliometric and content analysis, we identify leading journals, countries, institutions, authors, articles, and related research questions that mostly contributed to this field. Moreover, we provide a keyword/cartographic analysis identifying five leading research streams and their evolution over time, that we extensively discuss. Finally, we summarize the main questions proposed by the literature as a suggestion for future research
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
